Description
RELATED U.S. APPLICATIONS
[0001] The present application is a continuation-in-part of U.S.
patent application Ser. No. 09/675,436 filed on Sep. 29, 2000 and
entitled, "PROSTATE MASSAGE APPARATUS", presently pending.
STATEMENT REGARDING FEDERALLY SPONSORED RESEARCH OR DEVELOPMENT
[0002] Not applicable.
REFERENCE TO MICROFICHE APPENDIX
[0003] Not applicable.
FIELD OF THE INVENTION
[0004] The present invention relates to apparatus for the treatment
of hemorrhoids. More particularly, the present invention relates to
devices for massaging internal and external hemorrhoids by the
self-movement of the device. The present invention also relates to
devices that are held within the anal canal and are driven by the
pressure of the anal sphincter and by peristaltic activity of the
surface of the anal canal for the purpose of massaging the internal
and external hemorrhoids.
BACKGROUND OF THE INVENTION
[0005] A hemorrhoid is a protrusion of the internal intestinal
mucosa into the lumen of the rectum and, at times, outside the
body. If untreated, a hemorrhoid can be painful and can cause
irritation, discomfort and a soiling of clothing (typically
underwear). Further, the untreated hemorrhoid can become thrombose,
ulcerate and be prone to infection.
[0006] One current technique for treating external hemorrhoids
involves the topical application of emollients, prescription and
other over-the-counter medications. However, it is generally well
accepted within the medical community that the key to proper
hemorrhoidal care is to keep the area clean and to minimize
inflammation. Emollients and creams tend to trap fecal film minutia
on the surface of the skin. This fecal film and minutia can serve
as an additional source of irritation and inflammation.
Additionally, sitz baths are the currently preferred technique for
treating uncomplicated hemorrhoids.
[0007] Sitz bath treatment involves soaking the affected area in a
warm water bath three to four times per day. However, frequent
bathing is impractical and inefficient for the average patient.
Further, cold water is now recognized as being more effective in
treatment of hemorrhoids than warm water. The obvious discomfort of
a cold water bath is a significant limitation on the efficacy of
the sitz bath treatment technique.
[0008] Anal-treatment dilators in the form of a hollow, relatively
thin-walled, rotationally symmetrical cone are known. The cone is
dimensioned to dilate the anus. Ointment can then be applied
through the dilator to the hemorrhoidal tissues. However, it is
often difficult to properly apply the ointment to the hemorrhoidal
tissues since the ointment is often wiped off the instrument as it
is introduced into the outer region of the anus.
[0009] In contrast to the ointment-type hemorrhoidal treatment
devices, there are several anal treatment dilators and mechanical
devices that are intended to facilitate the treatment of
hemorrhoidal tissues. For example, U.S. Pat. No. 3,675,642, issued
on Jul. 11, 1942, describes a stationary device having a shoulder
at the bottom thereof which restricts free movement of the device
within the rectum. The device has a diameter of greater than one
inch. This large diameter will serve to induce the evacuative
response of the anorectal area. The diameter of this device narrows
by less than 1.5 inches from the base flange toward the top of the
device. This large area of the narrowing tapered surface receives a
downward thrust force from the lateral pressure of the anorectal
area.
[0010] U.S. Pat. No. 4,263,914 describes a device which massages
the anal canal manually. U.S. Pat. No. 4,583,542, issued on Apr.
22, 1986 to Z. R. Boyd, describes a stationary device with free
self-movement which is restricted by a circumferential shoulder of
the head and a large flange associated with the shaft. This device
is intended to stay in a stationary position. U.S. Pat. No.
5,797,950, issued to the present inventor, utilizes the anal
sphincter contraction to massage the prostate by reciprocal linear
movement of the apparatus. The device is held by a rod set against
the perineum region. U.S. Pat. No. 6,589,193, to the present
inventor, utilizes the entire anal canal's static and dynamic
lateral pressure, along with the peristaltic activity of the anal
canal, in order to massage the internal and external hemorrhoids.
With the exception of U.S. Pat. No. 6,589,193, none of the prior
art patents mobilizes the device in order to message the internal
and external hemorrhoids substantially by the activity of the
pecten within the anal canal.
[0011] It is an object of the present invention to provide a
hemorrhoidal treatment apparatus that induces peristaltic movement
within the anal canal.
[0012] It is another object of the present invention to provide a
hemorrhoidal treatment device which effectively massages the
internal and external hemorrhoids without aggravating the
condition.
[0013] It is still a further object of the present invention to
provide a hemorrhoidal treatment device which utilizes the
peristaltic activity within the anal canal for back-and-forth
movement.
[0014] It is a further object of the present invention to provide a
hemorrhoidal treatment device which relies on the peristaltic
movement of the anal canal to consume a large amount of energy and
increase fresh blood circulation to the anorectal area for
improving hemorrhoidal conditions.
[0015] It is another object of the present invention to provide a
small diameter device having smooth curved surfaces so as to avoid
aggravating the hemorrhoidal condition.
[0016] It is still a further object of the present invention to
provide a hemorrhoidal treatment device which is easy to use,
inexpensive, and easy to manufacture.
[0017] These and other objects and advantages of the present
invention will become apparent from a reading of the attached
specification and appended claims.
BRIEF SUMMARY OF THE INVENTION
[0018] The present invention is a device for gently and naturally
massaging the internal and external hemorrhoids without using
external forces applied to the device. The device is movably held
by the pecten within the anal canal so as to slightly move backward
and forward, by itself, by way of the peristaltic activity of the
pecten wall. The pecten is a narrow, concave portion of the anal
canal. These slight movements of the device massage the internal
and external hemorrhoids without aggravating the condition. The
peristaltic movement within the pecten consumes a large amount of
energy so as to increase fresh blood circulation to the anorectal
area to improve the hemorrhoidal conditions.
[0019] The present invention comprises a shaft having a first end
section, a middle section, and a narrow section. The first end
section has a curved surface formed at the end thereof. This first
end section has a cylindrical or narrowly tapering surface
extending toward the middle section. The middle section is formed
from a cylindrical shaft portion. The cylindrical shaft portion can
have either a concave or a convex surface with an almost equal
diameter at the ends thereof. This will avoid the influence of the
lateral pressure of the internal hemorrhoidal area. The average
diameter of the middle section will be between 3/8 inch to 5/8
inch. This small diameter will serve to optimize the activity of
the pecten and to decrease the influence of the lateral pressure of
the internal hemorrhoidal area. The middle section has a length of
no more than one inch. The narrow section is located on an end of
the middle section opposite the first end section. This narrow
section has an area between a first end thereof and a second end
thereof. This narrow section is provided so that the pecten can
grip the device. The narrow section has a length of no more than
one inch. The diameter of the device at the first end of the narrow
section and at the second end of the narrow section is equal. The
distance between the end of the first end section and the second
end of the narrow section is between one and a half inches and four
inches.

DETAILED DESCRIPTION OF THE INVENTION
[0024] FIG. 1 shows a hemorrhoid treatment device 10 in accordance
with the preferred embodiment of the present invention. The device
10 is utilized so as to work with the pecten within the anal canal.
This pecten is a narrow concave portion of the anal canal.
[0025] The device 10 has a shaft with a first end section 11, a
middle section 20 and a narrow section 17. The first end section 11
extends between the end 7 of the device and the end 15 of the
middle section 20 (designated with broken line "h"). The middle
section 20 is located between first end 15 and opposite end 16. The
narrow section 17 is located between the opposite end 16 of the
middle section 20 and an opposite end 18 of the narrow section 17
(indicated by broken line "g").
[0026] The first end section 11 has a curved surface 12 at end 7.
The curved surface 12 extends outwardly and downwardly from the end
7 in a direction toward the middle section 20. This curved surface
12 terminates in area 13 of the first end section 11. A cylindrical
surface 14 extends from area 13 to the end 16 of the narrow section
17. The narrow section 17 is illustrated as extending in a concave
manner between the ends 16 and 18 thereof. The device 10 can be
terminated at the end 18 of the narrow section 17, if desired.
However, in the preferred embodiment of the present invention, a
handle shaft 21 is secured to the end 18 of the narrow section 17.
Handle 22 is attached to the end of the handle shaft 21 opposite
the middle section 17. The length from the end 7 of the first
section 11 to the end 18 of the narrow section 17 is between one
and a half inches and four inches.
[0027] Similarly, the distance between the broken line (h) at the
end 15 of the middle section 20 and the broken line (g) at the end
18 of the narrow section 17 is between one inch and one and a half
inches, inclusive. This distance represents an entire length of the
human anal sphincter. The human sphincter includes the internal
hemorrhoid area, the pecten, and the subcutaneous external
sphincter. The subcutaneous external sphincter includes the
external hemorrhoids. The length between the end 15 of the middle
section 20 and the end 16 of the narrow section 17 is between
one-half inch to three-quarters inch. This distance represents the
length of the internal hemorrhoid area. The length between the end
16 and the end 18 of the narrow section 17 is between one-half inch
and three-quarters inch inclusive. This distance represents the
length of the pecten. The diameters of the end 15 of the middle
section 20 and the end 16 and the middle section 20, and the end 18
of the narrow section 17, are almost equal. Typically, these
diameters will be between three-eighths inch and three-quarters
inch. In the preferred embodiment of the present invention, the
optimum diameters would be between three-eighths inch to one-half
inch.
[0028] The area between the area 13 of the first end section 11 and
the opposite end 15 of the first end section 11 can be eliminated
or replaced with various shapes of surfaces. Since this first end
section 11 is outside the territory of the sphincter, the lateral
pressure of the sphincter will not influence the first end section
11.
[0029] The cylindrical surface of the middle section 20 can include
a slightly narrowing or widening tapered surface. If such a tapered
surface is used, then the angle of taper should be less than eight
degrees as extending from the end 15 of the middle section 20 to
the end 16 of the narrow section 17. When the middle section 20 has
a widening tapered surface from the end 15 of the middle section to
the end 16 of the narrow section 17, the diameter of the narrowest
cross section of the narrow section 17 is no more than the diameter
of a cross section of the end 15 of the middle section 20.
[0030] FIG. 2 shows the relationship between the hemorrhoid
treatment device 10 and components of the anal canal. The main
components of the anal canal are the internal hemorrhoid area 80,
the pecten 81 and the subcutaneous external sphincter 83. This
subcutaneous external sphincter 83 contains the external
hemorrhoids. The upper portion 85 of the internal hemorrhoid area
80 shows the ampulla of the rectum. When the device 10 is in use,
it is inserted into the anal canal as the narrow section 17 of the
device 10 fits to match the contours of the pecten 81. The device
10 is constructed so that the length of the narrow section 17 of
the device 10 is between one-half inch to three-quarters inch in
order to fit the typical length of the pecten 81.
[0031] The pecten 81 spans more than the middle third of the anal
canal. The pecten 81 will have a length of about one-half inch to
three-quarters inch. The pecten 81 is characterized by the
formation of a thick hardened ring of fibrous tissue with resulting
stenosis and contracture to form a narrow passage. The pecten 81
serves as a divider for the anal canal. When a small object is
located in the upper section of the pecten, the pecten 81 retrieves
the object within the rectum 85. When the object is at the lower
section of the pecten 81, the pecten 81 serves to push the object
out of the anus.
[0032] When the pecten 81 accommodates to the narrow section 17 of
the device 10, the peristalistic motion of the pecten alone cannot
clear out the device 10 from the pecten 81. This is because the
ends 16 and 18 of the narrow section 17 serves as a bulwark. In
other words, these ends 16 and 18 of the narrow section 17 send
conflicting messages to the pecten 81 on whether to retrieve or
evacuate the device from the anal canal. As the peristalistic
motion within the pecten 81 continues to try to remove the device
10 from the pecten 81, the device 10 slightly moves backward and
forward for a short distance within the pecten 81. Additionally,
since the diameter of the cylindrical surface of the shaft
throughout the middle section 20 is constant, there will be no
thrust force caused by the lateral pressure of the internal
hemorrhoidal area to the middle section 20 and will not interfere
the gripping ability of the pecten 81.
[0033] In those circumstances when the diameter of the middle
section 20 is less than one-half inch and in those circumstances
when the middle section 20 has a small tapered surface, the thrust
force caused by the lateral pressure of the internal hemorrhoidal
area has a nominal effect on the device in comparison to the
gripping power of the pecten 81. The ideal diameter of the end 16
and the end 18 of the narrow section 17 is less than three-quarters
of the length of the pecten 81.
[0034] When the surface between the points 30 and 31 adjacent to
the bottom 18 of the narrow section 17 has an average radius of
less than three-eighths inch, this surface will perform a strong
massage effect to the external hemorrhoidal area. The peristalistic
motion of the pecten will consume a large amount of energy. This
causes increased blood circulation and will cause an increased
temperature of the hemorrhoidal area. As a result, it can serve to
cure the hemorrhoidal condition.
[0035] FIG. 3 shows first alternative embodiment of the
hemorrhoidal treatment device 700 of the present invention. The
device 700 has an first end section 711, a middle section 720 and a
narrow section 717. The end section 711 has a curved top surface
712 extending from end 707 to an area 713. A narrowing tapered
surface 714 extends from the area 713 to the end 715 of the middle
section 720, indicated by broken line (h) in the illustration of
FIG. 3.
[0036] In the alternative embodiment of FIG. 3, the middle section
720 is illustrated as extending in a convex manner between the end
715 of the middle section 720 and the end 716 of the narrow section
717. The narrow section 717 is illustrated as extending in a
concave manner between the end 716 and the end 718. End 718 of the
narrow section 717 is illustrated with broken line (g). The device
700 can be terminated at the end 718 of the narrow section 717.
However, as illustrated in FIG. 3, a handle shaft 721 can be
attached to the end 718 of the narrow section 717. The length from
the area 713 of the first end section 711 to the end 718 of the
narrow section 717 is between one inch and four inches. The
distance between the end 715 of the middle section 720 and the end
718 of the narrow section 717 is between one inch and one and a
half inches inclusive. The length between the end 715 of the middle
section 720 and the end 716 of the narrow section 717 is between
one-half inch and three-quarters inch, inclusive. The length
between the end 716 and the end 718 of the narrow section 717 is
between one-half inch and three-quarters inch, inclusive.
[0037] The diametric difference between the end 715 of the middle
section 720 and the end 716 of the narrow section 717 is .+-.20%.
As a result, the convex surface of the middle section 720 will not
yield significant thrust forces caused by the lateral pressure of
the internal hemorrhoid area and will not interrupt or interfere
with the gripping ability of the pecten. The diameters of a cross
section of the end 716 and the end 718 of the narrow section 717
are almost equal. This diameter can be between three-eighths inch
to three-quarters inches, inclusive.
[0038] In the alternative embodiment shown in FIG. 3, the end
section 711 can be replaced by various shapes of surfaces extending
from the area 713 to the end 715 of the middle section 720.
[0039] FIG. 4 shows a second alternative embodiment of the
hemorrhoid treatment device 900 of the present invention. The
device 900 has an end section 911, a middle section 920 and a
narrow section 917. The end section 911 has a curved surface 912
extending from area 913 to end 907 of the device 900. A cylindrical
surface 914 will extend from the area 913 to the end 915 of the
middle section 920 at the area designated with a broken line (h) in
FIG. 4. The middle section 920 is illustrated as extending in a
concave manner between the end 915 of the middle section 920 and
the end 916 of the narrow section 917. The narrow section 917 also
extends in a concave manner between the end 916 and the end 918
thereof. The device 900 can be terminated at the bottom 918 of the
narrow section 917, as illustrated by broken line (g) in FIG. 4. In
the preferred form of this alternative embodiment, a handle shaft
921 is secured to the end 918 of the narrow section 917 of the
device 900. The length between the area 913 to the end 918 of the
narrow section 917 is between one inch and four inches,
inclusive.
[0040] The length between the end 915 of the middle section 920 and
the end 918 of the narrow section 917 is between one inch and
one-half inches, inclusive. The length between the end 915 of the
middle section 920 and the end 916 of the narrow section 917 is
between one-half inch and three-quarters inch, inclusive. The
length between the end 916 and the end 918 of the narrow section
917 is between one-half inch and three-quarters inch, inclusive.
The diametric difference between the end 915 of the middle section
920 and the end 916 of the narrow section 917 is .+-.20%. As a
result, the concave surface of the shaft at this middle section 920
does not yield significant thrust force effects caused by the
lateral pressure of the internal hemorrhoidal area and does not
interfere with or interrupt the gripping ability of the pecten. The
diameters of the end 916 and the end 918 of the narrow section 917,
at a cross sections thereof, is of almost equal. This diameter can
be between three-eighths inch to three-quarters inch, inclusive.
The diameter of the narrowest portion of the narrow section 917 is
no more than the diameter of the end 915 of the middle section
920.
[0041] In the present invention, it should be noted that the upper
portion 911 can be replaced by various shapes of surfaces that
