[0002] Not Applicable.
REFERENCE TO A MICROFICHE APPENDIX
[0003] Not Applicable.
BACKGROUND OF NON-LIMITING EXEMPLARY EMBODIMENT(S) OF THE PRESENT
DISCLOSURE
Technical Field
[0004] These non-limiting exemplary embodiment(s) relates to
medical instrument handles and, more particularly, to an ergonomic
multi-functional handle used to manipulate a medical instrument
such as an electrosurgical, monopolar, laparoscopic instrument, for
example, while reducing user fatigue.
Prior Art
[0005] Surgery is a learned skill requiring many years of training
to develop an understanding of medical procedures, disease
processes and healing that far exceed the basic medical principles.
The surgeon must develop hand-to-eye coordination and acquire
skills utilizing a variety of highly specialized medical
instruments. The medical instruments and tools are an extension of
the surgeon's hand. The surgeon's ability to perform the medical
procedures with instruments and tools designed to benefit skill is
paramount to the successful outcome for the patient. To enhance the
medical performance to better serve the patient means developing
instrument handles which are responsive, sensitive and
ergonomically designed to benefit the natural motions of the human
hand.
[0006] For example, laparoscopic instruments have been heavily
developed for use by surgeons during medical procedures since
around 1980s. There are many advantages of laparoscopic surgery
compared with open procedure. These advantages include: reduced
hemorrhaging which reduces needing a blood transfusion, smaller
incision which reduces pain and shortens the recovery time of the
patient, reduced scarring, reduced chances of needing pain
medication, reduced hospital stays and quicker return to everyday
life, and reduced risk of contamination and infection.
Disadvantages of a laparoscopic procedure include: limited range of
motion in the medical site, poor depth perception by the surgeon,
and often laparoscopic tools are not perceived as moving in the
same direction as the surgeon's hands.
[0007] In a variety of medical devices used for a diversity of
medical or non-medical procedures, devices are designed with a
dedicated handle or proximal end and a distal or actuation end.
Typically medical device handles prescribe how they will be held in
the hand by the layout of their handle shape or position of digit
retaining portions. In instruments that contain loops, such as can
be found in scissors type devices or grasping type devices, the
loops are used for opening and closing the end effector, whether
that is a scissors, grasper, clamp or similar device. In medical
devices and more specifically minimally invasive or laparoscopic
devices, a wide variety of angles of use can be generated.
Typically a digit-looped device locks the digits and hand into a
single orientation that can only function comfortably across a
limited range of angles. Both in angles distal or away from the
user and oblique angles or angles acutely to the side of the user,
devices with digit loops move beyond their effective comfort range
and promote hand stress and fatigue. This stress and discomfort is
the result of creating unnatural hand postures. These hand postures
can create severe wrist adduction or flexion causing discomfort and
a loss of strength or leverage to operate the device. In certain
instruments such as instruments used for minimally invasive or
laparoscopic dissection, a surgeon may operate a looped device for
long periods of time, across a wide range of angles.
[0008] In other conventional instruments, the handle comprises two
holes for insertion of middle digit in one ring and digit in the
other ring. The sizes of these rings are often small and not
optimized for all types of hand sizes. This method in which the
whole instrument is supported by only a thumb and finger and in
which case, the hand and wrists make a very awkward and unnatural
angle with respect to the angle of use is often very cumbersome to
the surgeon and extended use of instrument in this position causes
severe fatigue and hand pain. This results in painful situations
during extended surgeries.
[0009] Accordingly, a need remains for an ergonomic medical
instrument handle to overcome at least one of the above-noted
shortcomings. The non-limiting exemplary embodiment(s) satisfies
such a need by providing an ergonomic medical instrument handle
that is convenient and easy to use, lightweight yet durable in
design, versatile in its applications, and designed for easily and
conveniently enabling a user to articulate his/her digit while
operating the medical instrument handle and thereby reduce fatigue
and discomfort during extended medical procedures.
BRIEF SUMMARY OF NON-LIMITING EXEMPLARY EMBODIMENT(S) OF THE
PRESENT DISCLOSURE
[0010] In view of the foregoing background, it is therefore an
object of the non-limiting exemplary embodiment(s) to provide an
ergonomic multi-functional handle used to manipulate a medical
instrument such as an electrosurgical, monopolar, laparoscopic
instrument, for example, while reducing user fatigue. These and
other objects, features, and advantages of the non-limiting
exemplary embodiment(s) are provided by a multi-functional handle
for manipulating a medical instrument. Such a multi-functional
handle includes a body capable of being gripped by a hand of a user
and capable of being in communication with a medical instrument.
Such a body includes a first portion and a second portion coupled
thereto such that the second portion is displaced relative to the
first portion. In this manner, one of the first portion and the
second portion is capable of manipulating the medical
instrument.
[0011] In a non-limiting exemplary embodiment, the multi-functional
handle further includes a first trigger assembly. Such a first
trigger assembly preferably includes an actuation arm, and a
primary digit-receiving member coupled to the actuation arm. The
first trigger assembly is pivotally coupled to the body in such a
manner that the actuation arm is capable of actuating the medical
instrument independently from movement of the primary
digit-receiving member. In this manner, the primary digit-receiving
member is selectively displaced between alternate orientations
relative to a position of the body and relative to a position of
the actuation arm, respectively.
[0012] In a non-limiting exemplary embodiment, when each of the
first portion, second portion and first trigger assembly are
present, both the first trigger assembly as well as one of the
first portion and second portion operates the medical
instrument.
[0013] In a non-limiting exemplary embodiment, when each of the
first portion, second portion and first trigger assembly are
present, either the first trigger assembly operates the medical
instrument or one of the first portion and second portion operates
the medical instrument.
[0014] In a non-limiting exemplary embodiment, the primary
digit-receiving member is selectively displaced between alternate
orientations relative to a position of the body and relative to a
position of the actuation arm, respectively.
[0015] In a non-limiting exemplary embodiment, the primary
digit-receiving member is linearly reciprocated along a linear
travel path extending outwardly from a proximal end of the
actuation arm.
[0016] In a non-limiting exemplary embodiment, the primary
digit-receiving member is freely articulated about an x-axis,
y-axis and z-axis.
[0017] In a non-limiting exemplary embodiment, the multi-functional
handle further includes a secondary digit-receiving member attached
to the body.
[0018] In a non-limiting exemplary embodiment, the secondary
digit-receiving member is fixedly coupled to the body.
[0019] In a non-limiting exemplary embodiment, the multi-functional
handle further includes a tertiary digit-supporting member attached
to the body.
[0020] In a non-limiting exemplary embodiment, the tertiary
digit-supporting member is fixedly coupled to the body.
[0021] In a non-limiting exemplary embodiment, the tertiary
digit-supporting member is pivotally coupled to the body.
[0022] In a non-limiting exemplary embodiment, the tertiary
digit-supporting member is pivotally coupled to the second portion
and extends proximally away therefrom.
[0023] In a non-limiting exemplary embodiment, the tertiary
digit-supporting member is resiliently coupled to the second
portion thereby returning to an equilibrium position after being
biased to an offset position.
[0024] The present disclosure further includes a method of
utilizing a multi-functional handle for manipulating a medical
instrument. Such a method includes the steps of: obtaining and
gripping a body in a hand of a user wherein the body includes a
first portion and a second portion coupled thereto; and displacing
the second portion relative to the first portion such that one of
the first portion and the second portion manipulates a medical
instrument.
[0025] There has thus been outlined, rather broadly, the more
important features of non-limiting exemplary embodiment(s) of the
present disclosure so that the following detailed description may
be better understood, and that the present contribution to the
relevant art(s) may be better appreciated. There are additional
features of the non-limiting exemplary embodiment(s) of the present
disclosure that will be described hereinafter and which will form
the subject matter of the claims appended hereto.

is disclosed. Such a handle 100 includes a body 150 having a
plurality of digit-receiving members (primary digit-receiving
member 131, secondary digit-receiving members 155, 156 and tertiary
digit-supporting member 157) and a first trigger assembly 120
operatively coupled to second trigger assembly 130. A third trigger
assembly 140 locks the primary digit-receiving member 131 at a
desired position relative to the body 150.
[0090] The term digit, as used in the present disclosure, is
intended to mean any portion(s) of a user's hand, thumb,
metacarpals, phalanges, fingers, etc. The terms "first position"
and "second position" mean both up and down positions relative to
each other for permitting and prohibiting movement of the first
trigger assembly 120. For example, the "first position" can be
either the up position or down position. The "second position" can
be either the up position or down position, so long as it is not
the same as the "first position."
[0091] In preferred embodiments, as shown in FIGS. 1-26A, the
ergonomic multi-functional handle 100 may be operated with a second
trigger assembly 130 (described herein below).
[0092] In a preferred embodiment, as shown in FIGS. 27-28A, the
ergonomic multi-functional handle 100 may be operated without the
second trigger assembly 130 (described herein below).
[0093] FIGS. 1-28A illustrate various embodiments of a
multi-functional handle 100 for manipulating a medical instrument
180. Such a multi-functional handle 100 includes a body 150 capable
of being gripped by a hand of a user and further capable of being
in communication with a medical instrument 180 via a distal end 101
equipped with a rotation knob 102 as well as a first trigger
assembly 120 (described in more detail herein below). The secondary
digit-receiving members 155, 156 may include a curvilinear distal
outer surface 108 having a concave radius of curvature suitable
sized and shaped to receive a user digit thereagainst. Curvilinear
surfaces 109, 110 may be ribbed or otherwise corrugated to receive
one or more user digits. Such surfaces 108, 109, 110 may be
portions of complete loops and/or incomplete loops. Body 150
includes a first portion 151 and a second portion 152 coupled
thereto such that the second portion 152 is displaced relative to
the first portion 151. In this manner, one of the first portion 151
and the second portion 152 is capable of manipulating the medical
instrument 180. The terms "first portion" 151 and "second portion"
152 may include upper and lower portions of the body 150, which may
include one or more of the primary digit-receiving member 131,
secondary digit-receiving member 155, 156, and tertiary
digit-supporting member 157. Also, the "first portion" 151 and/or
the "second portion" 152 may be formed from deformably resilient
material and/or rigid plastic.
[0094] In a non-limiting exemplary embodiment, as shown FIGS.
1-26A, the multi-functional handle 100 further includes a first
trigger assembly 120. Such a first trigger assembly 120 preferably
includes an actuation arm 129, and the primary digit-receiving
member 131 coupled to the actuation arm 129. The first trigger
assembly 120 is pivotally coupled to the body 150 in such a manner
that the actuation arm 129 is capable of actuating the medical
instrument 180 independently from movement of the primary
digit-receiving member 131. In this manner, the primary
digit-receiving member 131 is selectively displaced between
alternate orientations relative to a position of the body 150 and
relative to a position of the actuation arm 129, respectively.
[0095] In a non-limiting exemplary embodiment, when each of the
first portion 151, second portion 152 and first trigger assembly
120 are present, both the first trigger assembly 120 as well as one
of the first portion 151 and second portion 152 operates the
medical instrument 180.
[0096] In a non-limiting exemplary embodiment, when each of the
first portion 151, second portion 152 and first trigger assembly
120 are present, either the first trigger assembly 120 or at least
one of the first portion 151 and second portion 152 operates the
medical instrument 180.
[0097] In a non-limiting exemplary embodiment, the primary
digit-receiving member 131 is selectively displaced between
alternate orientations relative to a position of the body 150 and
relative to a position of the actuation arm 129, respectively.
[0098] In a non-limiting exemplary embodiment, the primary
digit-receiving member 131 is linearly reciprocated along a linear
travel path extending outwardly from a proximal end of the
actuation arm 129.
[0099] In a non-limiting exemplary embodiment, the primary
digit-receiving member 131 is freely articulated about an x-axis,
y-axis and z-axis.
[0100] In a non-limiting exemplary embodiment, the multi-functional
handle 100 further includes at least one secondary digit-receiving
member 155, 156 attached to the body 150.
[0101] In a non-limiting exemplary embodiment, the secondary
digit-receiving member 155, 156 is fixedly coupled to the body
150.
[0102] In a non-limiting exemplary embodiment, the multi-functional
handle 100 further includes a tertiary digit-supporting member 157
attached to the body 150.
[0103] In a non-limiting exemplary embodiment, the tertiary
digit-supporting member 157 is fixedly coupled to the body 150.
[0104] In a non-limiting exemplary embodiment, the tertiary
digit-supporting member 157 is pivotally coupled to the body
150.
[0105] In a non-limiting exemplary embodiment, the tertiary
digit-supporting member 157 is pivotally coupled to the second
portion 152 and extends proximally away therefrom.
[0106] In a non-limiting exemplary embodiment, the tertiary
digit-supporting member 157 is resiliently coupled to the second
portion 152 thereby returning to an equilibrium position after
being biased to an offset position.
[0107] The present disclosure further includes a method of
utilizing a multi-functional handle 100 for manipulating a medical
instrument 180. Such a method includes the steps of: obtaining and
gripping a body 150 in a hand of a user wherein the body 150
includes a first portion 151 and a second portion 152 coupled
thereto; and displacing the second portion 152 relative to the
first portion 151 such that one of the first portion 151 and the
second portion 152 manipulates a medical instrument 180.
[0108] In a non-limiting exemplary embodiment, as perhaps best
shown in FIGS. 1 and 14, the first trigger assembly 120 is
operatively coupled to the medical instrument 180 (e.g.,
laparoscopic tool 180). The medical instrument 180 includes a
rectilinear drive rod 113 having a proximal end operatively coupled
to the handle 100, as will be explained in more detail hereinbelow.
A distal end of the drive rod 113 contains a linkage assembly 111
operatively coupled to a conventional jaw assembly 104. One skilled
in the art understands the conventional operation of such
components. The linkage assembly 111 includes a first link lever
163 and a second link lever 169 pivotally coupled to opposite sides
of the distal end of the drive rod 113. Manipulation of the drive
rod 113--via first trigger assembly 120--causes articulated of the
first and second link levers 163, 169 about a common fulcrum axis
162 at the distal end of the drive rod 113. Such first and second
link levers 163, 169 are also pivotally coupled to first jaw 166
and second jaw 167, at joints 164, 168, respectively. First and
second jaws 166, 167 are pivotally coupled to each other via a jaw
pin 165. In this manner, when the distal end of the drive rod 113
is linearly urged--along distance 161--towards the first and second
jaws 166, 167, the first and second link levers 163, 169 are caused
to pivot along first rotational directions, away from a
longitudinal axis 190 of the drive rod 113. Such pivotal movement
urges apart the first and second jaws 166, 167 to an open position.
Retraction of the drive rod 113--along distance 161--away from the
jaw pin 165 causes the first and second link levers 163, 169 to
articulate towards the longitudinal axis 190 of the drive rod 113
and thereby articulate the first and second jaws 166, 167 towards a
closed position.
[0109] Referring to FIG. 2, in a non-limiting exemplary embodiment,
a partially exposed side elevational view illustrating the
interrelationship between the internal components of the
multi-functional handle 100 shown in FIG. 1, is disclosed. The
first trigger assembly 120 operates the medical instrument 180
wherein the rectilinear drive rod 113 is housed within the shaft
103. A proximal end of the drive rod 113 is attached to a distal
end of the actuation arm 129. Such a drive rod 113 may be connected
to the actuation arm 129 via a ball/socket joint 128, 142 or other
fastener suitable for reciprocating the drive rod 113 along a
linear travel path 161 defined parallel to the longitudinal axis
190 of the shaft 103 (as perhaps best shown in FIG. 14). FIGS. 6
and 8 illustrate the drive rod ball joint 128 and actuation arm 129
ball socket 142. Articulation of the first trigger assembly 120 is
effectuated by manual manipulation of the actuation arm 129 along
the arcuate path illustrated by the arrow 112. Connection between
the actuation arm 129 and drive rod 113 is spaced from the first
pivot axis 126 about which the first trigger assembly 120 pivots. A
rotation knob joint 105 is attached to the drive rod 113 at a
distal location of the body 150 so that the medical instrument 180
can be selectively articulated via rotation of the actuation arm
129 at a proximal end of the body 150. Of course, alternately, the
position of the actuation arm 129 may be located at a distal end of
body 150.
[0110] Referring to FIG. 2, in a non-limiting exemplary embodiment,
an electrical current may be supplied to the medical instrument 180
via a high-frequency (HF) connector plug 107 extending outwardly
and away from a top of the body 150. A HF connector lead 106 is
communicatively coupled to the connector plug 107 and travels
downward into a hollow cavity of the body 150 wherein it maintains
electrical communication with the drive rod 113.
[0111] In a non-limiting exemplary embodiment, an energy source
such as a tissue-altering energy source may be communicatively
coupled to the handle 100. Exemplary tissue-altering energy sources
may generate a heat signal, acoustic signal, microwave signal,
light signal, etc., as well-understood by one of ordinary skill in
the art. Each tissue-altering energy source may include different
components for interfacing with the body 150 and/or the medical
instrument 180. Thus, the HF connector plug 107 and lead 106 are
not a necessity and are merely provided as an illustrative example;
not restrictive.
[0112] Referring to FIG. 3, in a non-limiting exemplary embodiment,
an enlarged view of the second trigger assembly 130, taken in FIG.
2, is disclosed. As noted above, the second trigger assembly 130
permits selective articulation of a portion--actuation arm 129--of
the first trigger assembly 120 along the arcuate path 112 for
manipulating the medical instrument 180 (e.g., jaws). Of course,
one skilled in the art understands a variety of medical instruments
180 may be manipulated by movement of the first trigger assembly
120.
[0113] In a non-limiting exemplary embodiment, the second trigger
assembly 130 is employed to selectively lock the actuation arm 129
at alternate positions, as desired. Thus, while the first trigger
assembly 120 permits operation of the medical instrument 180, the
second trigger assembly 130 enables the user to lock the first
trigger assembly 120 at a desired position thereby preventing
further manipulation of the medical instrument 180.
[0114] In a non-limiting exemplary embodiment, as perhaps best
shown in FIGS. 3, 4 and 7, the second trigger assembly 130
preferably includes a ratchet cam shaft 119 formed at the second
pivot axis 127. A ratchet trigger 153 is statically coupled to the
ratchet cam shaft 119 and is disposed exterior of the body 150. The
ratchet trigger 153 pivots about the second pivot axis 127 thereby
causing a ratchet cam shaft arm 116 to articulate in a
corresponding direction. For example, when the ratchet trigger 153
is rotated clockwise, the ratchet cam shaft arm 116 also rotates
clockwise; and visa-versa.
[0115] In a non-limiting exemplary embodiment, a ratchet cam shaft
snap fit 117 is formed at an end of the ratchet cam shaft arm 116
and locks to a snap fit anchor bracket 117 statically housed within
the body 150. For example, the snap fit anchor bracket 117 may be
friction locked, magnetically locked, or locked via other suitably
ways, without departing from the true spirit and scope of the
present disclosure. A ratchet pawl cam 121 is statically mated to
the ratchet cam shaft 119 and remains angled away from the ratchet
cam shaft arm 116 such that it selectively displaces one end of a
ratchet pawl 122. The ratchet pawl 122 has an opposite end anchored
to a ratchet pawl attachment boss 123 located distally of the first
pivot axis 126. In this manner, articulation of ratchet trigger 153
along a first rotational direction causes ratchet pawl cam 121 to
urge ratchet pawl 122 towards a ratchet arm 147 having a serrated
surface. A proximal end of the ratchet pawl 122 engages the ratchet
arm 147 teeth 118 and the ratchet cam shaft snap fit 117 locks the
ratchet trigger 153 at a locked position. Such cooperation between
the ratchet pawl 122, ratchet arm 147 and ratchet cam snap fit 117
prohibit premature or undesirable movement of the ratchet trigger
153, thereby maintaining the medical instrument 180 at a desired
orientation.
[0116] In a non-limiting exemplary embodiment, rotation of ratchet
trigger 153 in an opposite direction releases the ratchet cam snap
fit 117 and disengages the ratchet pawl 122 from the ratchet arm
147. Such disengagement permits the ratchet arm 147 to articulate
in sync with the actuation arm 129 of the first trigger assembly
120 thereby permitting manipulation of the medical instrument 180
as desired.
[0117] In a non-limiting exemplary embodiment, FIG. 4 illustrates
an enlarged side elevational view of the multi-functional handle
100 for articulation of the first trigger assembly 120 about the
first pivot axis 126. During manipulation of the medical instrument
180, the first trigger assembly 120 articulates about the first
pivot axis 126 and along a first arcuate path 112 while the ratchet
trigger 153 is at a lowered position (e.g., unlocked position). To
prohibit manipulation of the medical instrument 180, the ratchet
trigger 153 articulates along a second arcuate travel path 124, and
about a second pivot axis 127 offset from the first pivot axis 126.
When the ratchet trigger 153 is articulated to a raised position
(e.g., locked position), the actuation arm 129 is prohibited from
rotating along the arcuate path 112. As noted herein above,
raised/lowered positions maybe first/second positions and
visa-versa.
[0118] In a non-limiting exemplary embodiment, FIGS. 5 and 6 are
cross-sectional views showing the interrelationship between the
first trigger assembly 120, second trigger assembly 130 and third
trigger assembly 140. FIG. 8 is an enlarged perspective view
illustrating the interrelationship between the third trigger
assembly 140 and the actuation arm 129. FIG. 9 is an enlarged
perspective view illustrating the receiving aperture 146 of the
primary digit-receiving member 131. With reference to FIGS. 5-6 and
8-9, the digit locking switch is referred to as the third trigger
assembly 140. Such a mechanism permits selective movement of the
primary digit-receiving member 131, which may be a loop, for
example. Of course, the primary digit-receiving member 131 may be a
variety of shapes and should not be construed as limited to only a
loop shape.
[0119] In a non-limiting exemplary embodiment, the third trigger
assembly 140 is operably coupled to the actuation arm 129 and
primary digit-receiving member 131 of the first trigger assembly
120. The third trigger assembly 140 includes a switch 149 that is
linearly reciprocated along a slot 145 formed in the actuation arm
129. The switch 149 is partially inserted into the actuation arm
129 and has a switch follower 133 statically mated thereto. A
switch snap fit arm 134 extends downwardly and distally from the
switch follower 133, traveling along a path 141 aligned
substantially parallel to the reciprocating motion of the switch
149 above. A switch snap fit 135 is formed at a distal end of
switch arm 134. Grooves 137, 138 are formed within an interior wall
of the actuation arm 129. Such grooves 137, 138 are aligned
substantially parallel to the linear path 141 wherein, when the
switch snap fit 135 is positioned in a proximal groove 137, the
switch arm 134 is locked and prohibited from movement. When the
switch snap fit 135 is slidably inserted in the distal groove 138,
a locking shaft 132 is displaced outwardly from a receiving
aperture 146 thereby permitting movement of the primary
digit-receiving member 131. Although, the locking shaft 132 has a
hexagonal shape with a corresponding hexagonally shaped receiving
aperture 146, any number of interlocking shapes may be used to
prohibit movement of primary digit-receiving member 131. The
primary digit-receiving member 131 is coupled to the actuation arm
129 via a joint for maintaining the receiving aperture 146 within
the actuation arm 129 during movement of the primary
digit-receiving member 131; prevents primary digit-receiving member
131 from disengaging the locking shaft 132.
[0120] In a non-limiting exemplary embodiment, with reference to
FIGS. 4 and 7, an enlarged perspective view illustrating
articulation of the ratchet arm 153 about the second pivot axis 127
is disclosed. Also, a reference line 191 is shown passing through
the secondary digit-receiving members 155, 156 located along a
medial portion of the body 150. Such illustration in FIG. 7 shows
an optional movement of the medical instrument 180 along
approximately a 100 degree arcuate path. See also FIGS. 21 and 21A
for further illustration of the medical instrument 180 movement
relative to the medial portion of the body 150.
[0121] In a non-limiting exemplary embodiment, FIG. 10 is an
exploded view of the third trigger assembly 140 (e.g., locking
switch) communicatively coupled to the primary digit-receiving
member 131--of the first trigger assembly 120--shown in FIG. 1.
FIG. 10A is a perspective view of the third trigger assembly 140
illustrated in FIG. 10, wherein the primary digit-receiving member
131 is oriented at an aligned position. FIG. 10B is a perspective
view of the third trigger assembly 140 illustrated in FIG. 10,
wherein the primary digit-receiving member 131 is oriented at an
angularly offset position. While FIG. 10B illustrates partial
articulation of the primary digit-receiving member 131, it is
understood that the primary digit-receiving member 131 can be
articulated along 360 degree clockwise and counter clockwise paths
defined about longitudinal axis 192 passing through the actuation
arm 129.
[0122] FIG. 11 is an exploded view illustrating a non-limiting
exemplary embodiment of a linearly adjustable primary
digit-receiving member 231 (e.g., along linearly reciprocating path
295 extending from actuation arm 229). FIG. 11A is a perspective
view of the first trigger assembly 220 illustrated in FIG. 11,
wherein the primary digit-receiving member 231 is oriented at a
retracted position. FIG. 11B is a perspective view of the first
trigger assembly 220 illustrated in FIG. 11, wherein the primary
digit-receiving member 231 is oriented at an extended position. The
third trigger assembly 240 may include a detent or other fastener
to frictionally engage a tab 241 with a plurality of indentations
242 formed along a neck of the primary digit-receiving member
231.
[0123] FIG. 12 is an exploded view illustrating a non-limiting
exemplary embodiment of an angularly adjustable primary
digit-receiving member 331. FIG. 12A is a perspective view of the
first trigger assembly 320 illustrated in FIG. 12, wherein the
primary digit-receiving member 331 is oriented at a longitudinally
aligned position. FIG. 12B is a perspective view of the first
trigger assembly 320 illustrated in FIG. 12, wherein the primary
digit-receiving member 331 is oriented at an angularly offset
position. Thus, the third trigger assembly 340 may include a
ball/socket joint 341. While FIG. 12B illustrates partial
articulation of the primary digit-receiving member 331, it is
understood that the primary digit-receiving member 331 can be
articulated about x, y and z axes (e.g., ball/socket joint
341).
[0124] FIG. 13 is an exploded view illustrating a non-limiting
exemplary embodiment of tertiary digit-supporting member 1757
employed by the multi-functional handle 1700 shown in FIG. 1. FIG.
13A is a perspective view of the tertiary digit-supporting member
1757 illustrated in FIG. 13, wherein the digit-supporting member
1757 is oriented at an equilibrium position relative to the body
1750. FIG. 13B is a perspective view of the tertiary
digit-supporting member 1757 illustrated in FIG. 13, wherein the
tertiary digit-supporting member 1757 is oriented at an articulated
offset position. While FIG. 13B illustrates partial articulation of
the tertiary digit-supporting member 1757, it is understood that
the tertiary digit-supporting member 1757 can be selectively
articulated along clockwise and counter clockwise paths relative to
the secondary digit-receiving members 1755, 1756 of body 1750. A
snap fit fastener 1758 may be employed to selectively lock the
tertiary digit-supporting member 1757 at desired locations.
[0125] FIG. 15 is a side elevational view illustrating a
non-limiting exemplary embodiment of the handle 400 including a

to an upper portion 451 thereof. FIG. 15B is a rear elevational
view of the displaced lower portion 452 illustrated in FIG. 15.
FIG. 15A is a side elevational view illustrating the lower portion
452 angularly displaced relative to the upper portion 451. FIG. 15C
is a rear elevational view of the angularly displaced lower portion
452 illustrated in FIG. 15A. In such an embodiment, the bifurcated
region of the body 450 is located intermediately of the second
trigger assembly 430 and secondary digit-receiving members 455,
456. The connection between the upper portion 451 and lower portion
452 of the body 450 may be friction fitted, such as a snap-fit
arrangement or via a detent, for example. A resilient coupling may
also be employed for causing the lower portion 452 to automatically
return to an equilibrium position from a tensioned position. It is
noted that the lower portion 452 of the body 450 can be articulated
about x, y and z axes (e.g., ball/socket joint). Of course, the
upper portion 451 may move relative to a stationary lower portion
452 as well.
[0126] FIG. 16 is a side elevational view illustrating a

552 illustrated in FIG. 16A. In such embodiments, the bifurcated
region of the body 550 separates the secondary digit-receiving
members 555, 556 from each other. The connection between the upper
portion 551 and lower portion 552 of the body 550 may be friction
fitted, such as a snap-fit arrangement or via a detent, for
example. A resilient coupling may also be employed for causing the
lower portion 552 to automatically return to equilibrium from a
tensioned position. It is noted that the lower portion 552 of the
body 550 can be articulated about x, y and z axes (e.g.,
ball/socket joint). Of course, the upper portion 551 may move
relative to a stationary lower portion 552 as well.
[0127] FIG. 17 is a side elevational view illustrating a

illustrated in FIG. 17A. In such embodiments, the bifurcated region
is located intermediately of the secondary digit-receiving members
655, 656 and the tertiary digit-supporting member 657. Thus, the
tertiary digit-supporting member 657 is moved relative to
stationary secondary digit-receiving members 655, 656. The
connection between the upper portion 651 and lower portion 652 of
the body 650 may be friction fitted, such as a snap-fit arrangement
or via a detent, for example. A resilient coupling may also be
employed for causing the lower portion 652 to automatically return
to an equilibrium position from a tensioned position. It is noted
that the lower portion 652 of the body 650 can be articulated about
x, y and z axes (e.g., ball/socket joint). Of course, the upper
portion 651 may move relative to a stationary lower portion 652 as
well.
[0128] FIG. 18 is a perspective view illustrating a non-limiting
exemplary embodiment of the handle 700 including a bifurcated body
750 having a lower portion 752 pivotally coupled to an upper
portion 751 thereof. FIG. 18A is a perspective view illustrating
the lower portion 752 of FIG. 18 angularly offset relative to the
upper portion 751. In such an embodiment, the bifurcated region is
located intermediately of the second trigger assembly 730 and
secondary digit-receiving member 755, 756. The connection between
the upper portion 751 and lower portion 752 of the body 750 may be
friction fitted, such as a snap-fit arrangement or via a detent,
for example. A resilient coupling may also be employed for causing
the lower portion 752 to automatically return to an equilibrium
position from a tensioned position. It is noted that the lower
portion 752 of the body 750 can be articulated about x, y and z
axes (e.g., ball/socket joint). Of course, the upper portion 751
may move relative to a stationary lower portion 752 as well.
[0129] FIG. 19 is a perspective view illustrating a non-limiting
exemplary embodiment of the handle 800 including a bifurcated body
850 having a lower portion 852 pivotally coupled to a upper portion
851 thereof. FIG. 19A is a perspective view illustrating the lower
portion 852 of FIG. 19 angularly offset relative to the upper
portion 851. In such an embodiment, the bifurcated region separates
the secondary digit-receiving members 855, 856 from each other. The
connection between the upper portion 851 and lower portion 852 of
the body 850 may be friction fitted, such as a snap-fit arrangement
or via a detent, for example. A resilient coupling may also be
employed for causing the lower portion 852 to automatically return
to an equilibrium position from a tensioned position. It is noted
that the lower portion 852 of the body 850 can be articulated about
