CIRCUMCISION INSTRUMENT
Abstract
This surgical instrument has a clamping and holding member of
special construction especially suited for use in circumcision
operations involving the use of conventional hospital instruments
such as a probe, scalpel, and hemostat, for completing the
circumcision operation, while in the preferred form the instrument
will involve the use in combination of two main portions, with one
of these being the clamping and holding member, and the other a
cutting member, with the two members pivotally connected together
and guided in cooperative operating position, and when the two main
portions are principally formed of plastic, same can be discarded
at the end of the operation without need of sterilization for
reuse.

Description
BACKGROUND OF THE INVENTION
The present invention deals broadly with a surgical instrument, and
in its more specific phases with a disposable circumcision
apparatus which may be in the form of a clamping and holding member
alone, or in combination with a cutting member cooperatively and
pivotally joined to same.
In carrying out circumcision operations the common practice is to
use surgical scissors to shorten the boy baby's foreskin, a thing
which almost invariably causes not only a rough and crude finished
job, but often leads to bleeding and the need of stitches along the
cut edge. A recognition that this was far from an ideal procedure
led to the development of the circumcision instrument covered in
U.S. Pat. No. 2,212,133 133 which was and has been up to the
present time the most satisfactory instrument devised, although
several other nondisposable steel instruments have been proposed.
That instrument, however, was expensive to produce and keeping the
blade sharp presented problems. The present invention is an
improvement on the noted instrument and was devised with a view to
solving the noted circumcision problems as well as others which are
well known but for which there have been no instruments providing
wholly satisfactory commercial solutions wherein the trimming is
perfectly smooth and appears when healed, aside from a shortened
foreskin and mucosa, to be the same as though no operation had been
performed.
SUMMARY OF THE INVENTION
Accordingly, among the objects of the present invention is the
provision of a wholly satisfactory, highly simplified, and easy to
use circumcision instrument.
Another object is to produce a circumcision instrument which is
capable of being manufactured at such a low cost, and easy initial
sterilizability, that same can be used once and then discarded.
Another object is to provide a circumcision instrument with a
portion which can be clamped shut to crush the foreskin at the
desired point and seal the veins and arteries so as to eliminate
bleeding and the need of using stitches, while at the same time the
cutting portion, which is preferably part of the instrument, is
pivotally mounted on the clamping portion, may be moved in like
manner to the operation of the clamping portion and in doing so
will sever the foreskin along the adjacent surface of the clamping
portion at and outward of the crushed area.
A further object of this invention is to provide breakable latch
means for the clamping and holding portion so that removing the
instrument at the end of the circumcision operation will preferably
require breaking this latch and thus destroying the instrument so
that for the next circumcision operation a new and thoroughly
sterile instrument assembly will be used, thus doing away with
cleaning and resterilizing of the used instrument assembly, and
wherein the blade of a new instrument assembly will always be
unused and sharp.
A further object of the invention is to provide the cutting portion
of the instrument at its end remote from its hinge end with guide
means which hold same in proper shearing position relative to the
clamping and holding portion.
A further object is to provide the hinged end of the cutting
portion with an extension which closely fits and passes through the
hinge end of the clamping portion, and wherein the outer end of
said extension has an outward tapering wedge portion which binds
the hinge end of the cutting portion onto the adjacent side of the
clamping portion for improved, close fit, cutting action.
A further object of this invention is to provide the hinge end of
the clamping and cutting portions with means for normally holding
them in symmetrical relation to each other for stability and ease
of efficiently operating the surgical instrument.
A further object of this invention is to provide the clamping and
holding portion with a central depression or beveled portion on its
under side for the reception of the end of the glans penis while
avoiding any injury to same during the foreskin clamping and
holding step.
A further object of this invention is to provide the clamping
portion with means adjacent its hinge end to hold the side members
in alignment while at the same time stopping the side edge of the
foreskin from flowing under clamping pressure into the hinge
portion out of shearing position.
Still further objects and advantages of the invention will appear
as the description proceeds.

DESCRIPTION OF THE SPECIFIC EMBODIMENTS
Referring more particularly to FIGS. 1, 2 and 3, it will be noted
that this is a preferred form of the surgical instrument assembly
15 which has a clamping and holding member 16 with a cutting member
17 mounted on top of same. Clamping member 16, which is preferably
made from a tough but resilient plastic, has a pair of side members
18 and 19 unit joined together by means of an open side ring-shaped
hinge member 20, while at the opposite end of side member 18 there
is a hook latch member 21, FIGS. 2 and 5, adapted to engage latch
member 22 on the outer end of side member 19, which is shorter than
side member 18 to facilitate hooking engagement of latching members
21 and 22, FIG. 5. Hook latch member 21 is part of an extension of
side member 18, FIG. 2, and is provided with a weakening notch 23
and a breaking ear 24 so that the portion carrying hook latch 21
can be broken off to remove the clamping member at the end of the
operation as will be hereinafter set forth in further detail. At
least one of the adjacent faces of side members 18 and 19 is
preferably slightly bowed, preferably full length of same, toward
the other side member to provide a strong clamping action
offsetting any tendency for the side members to twist or spring
outward under conditions of use and not provide a firm clamping or
tissue crushing action. At the latching end of the clamping member
16 side members 18 and 19 are provided with oppositely disposed
enlarged and preferably corrugated finger grip members 25 and 26,
FIG. 2, to facilitate applying pressure for locking latch members
21 and 22 together under conditions of use. To stabilize side
members 18 and 19 as they closely approach each other and are
locked together, side member 19 is preferably provided with a pair
of opposite guide ears 27 and 28, FIG. 6. At the opposite end of
side members 18 and 19 adjacent ring-shaped hinge member 20, one of
the side members is preferably provided with a short recess 29,
FIG. 8, and the other with an aligned short tongue 30, to stabilize
the positioning of that end of side members 18 and 19 relative to
each other while at the same time forming a stop for a purpose to
be hereinafter explained. A recess and tongue combination 47,
similar to 29--30, is preferably used at the opposite side of
conical recess 46, FIG. 2, as a stop member, especially when
foreskin severing with a scalpel is to be done, as hereinafter
described.
The cutting member 17, except for the cutting blade, is preferably
made from a tough but resilient plastic and has a pair of side
members 31 and 32 connected together at one end with a partial
ring-shaped member 33, FIGS. 1, 2 and 4, with this ring-shaped
member having an extension 34, FIG. 9, closely fitting within the
open side, ring-shaped, member 20, and having on its lower or free
end an outward tapering wedge portion 35, which holds cutting
member 17 tight against the top or cutting member-engaging face of
clamping member 16. The upper end of extension 34 ends at shoulder
36 of member 33 and cooperates with said wedge portion 35 in
accomplishing said tight and stabilized fit. Preferably said open
side, ring-shaped, hinge member 20 is provided at its midpoint with
a radial upstanding rib 37, FIG. 10, fitting into a radial groove
38 in partial ring-shaped member 33. This combination of rib and
groove substantially symmetrically centers cutting member 17 on
clamping member 16 to facilitate operation of the surgical
instrument assembly 15 of the clamping and cutting members as will
be hereinafter set forth. At the outer end of side members 31 and
32, FIGS. 1 and 2, they are preferably provided with enlarged
finger grip members 39 and 40, respectively, which are preferably
corrugated to facilitate stabilized gripping under conditions of
use. Side member 32 has on its under face a cutting knife 41,
fastened thereto in conventional manner such as by the use of
plastic rivets 42, FIG. 11, together, if desired, with any suitable
adhesive. To hold cutting knife 41, which may be in the form of a
single edged razor blade, in shearing position tight against the
top face of side members 18 and 19 of clamping member 16 under
conditions of operation, FIG. 3, a support arm 43 for a guide ear
44 of side member 32 is preferably provided and passes and closely
fits under side member 19. For ease of use, clamping member 16, in
its free unlatched position, will stand open preferably in the
range of 40.degree. to 55.degree., and cutting member 17 in its
free open position is preferably about 5.degree. to 10.degree. more
open than the actual opening of clamping member 16 as shown
typically in FIG. 1.
Side members 18 and 19 of clamping member 16 are preferably
provided on their gripping adjacent edges with close spaced
interengaging longitudinal grooves 45, FIGS. 1, 2 and 7. Also at
the central portion of side members 18 and 19 of clamping member
16, as shown in FIGS. 2 and 7, the under portion of said side
members is provided with a relatively wide angle, preferably about
40.degree. to 60.degree. flaring substantially conical recess 46
for reception of the end of the glans penis for a purpose to be
hereinafter set forth.
OPERATION OF THE CIRCUMCISION INSTRUMENT
A disposable paper draping kit (not shown) including an outside
protective wrapper is preferably used, with this outside wrapper
used to drape the instrument table (not shown) with the sterile
inside face of same up. Inside the draping kit is a first sterile
sheet (not shown) which is used to drape the baby receiving table
(not shown). The baby boy is placed back down on this sheet and is
held on the table by the nurse who lightly keeps her elbows on the
baby's shoulders with the baby's head between them. Her hands hold
the baby's legs down and spread so that the operator can readily
perform the circumcision procedure. The hospital circulating nurse
adds the "preparation" solution to the disposable medicine cup (not
shown), which is part of the draping kit components along with the
circumcision instrument. She also supplies the necessary hospital
instruments to the instrument table, namely a probe, a hemostat,
and scissors; optionally there may be tissue forceps, and a needle
holder, as well as a suture and needle.
The operator then prepares the baby's penis with the sterile
solution and drapes the baby using a second sterile circumcision
sheet (not shown) having a suitable hole, through which the penis
is passed and the baby is then ready for the actual circumcision
operation which is carried on as follows: The operator grasps the
penis and with the probe separates the excess prepuce from the
glans penis. If necessary, a small dorsal slit is made in the
foreskin anteriorly in order to facilitate the separation from the
glans and pushing it back over the corona. After this has been
done, the foreskin is returned to its previous extended position. A
light is preferably used behind the penis so as to reflect the
shadow of the glans penis in the foreskin. The foreskin is then
grasped at right angles to the penis with a hemostat (not shown)
and stretched anteriorly. With the foreskin thus stretched the
clamping member 16 is applied with the glans penis fitting into the
conical recess 46 but not extending above it, whereupon the
clamping member 16 is closed and latched in that position. This
conical recess 46 pockets and prevents injury to the glans penis.
Then the cutting member 17 is manually closed, and in so doing the
cutting knife or blade 41 severs the excess foreskin without
injuring the glans penis which safely fits in the conical recess 46
on the underside of the clamping member 16. The cutting member 17
is then allowed to return to its open position, and if desired may
be broken at its hinge and removed. After about a minute the
clamping member 16 is released, preferably by breaking off the hook
latch member 21 at the weakening notch 23, whereupon the whole
surgical instrument assembly 15 is free to be discarded.
In carrying out this procedure the skin, mucus membrane, and all
blood vessels of the foreskin over the glans penis have been sealed
together by the crushing action of the clamping member, with
resultant sealing preventing bleeding. The sealed edge foreskin,
after the circumcision instrument has been removed, is then pushed
back over the corona by using the index finger and thumb of both
hands. It is held in this position for a moment until the mucus
membrane swells slightly causing the foreskin to remain in this
position. Whether a circumcision dressing is applied, or a small
piece of gauze is placed on the penis on which baciguent, or other
sterile ointment, has been applied, is optional. Actually no
dressing is required as there is very little, or no, bleeding.
However, ointment is desirably used since it prevents the cut edge
of the foreskin and the glans penis from adhering to the baby's
diaper. Stitches are seldom necessary, and the entire procedure
normally takes less than three minutes and all materials are
disposable except for the sterilizable instruments which have been
supplied by the hospital.
By omitting cutting member 17, the clamping member 16 can be used
alone, in the manner described above, and the severing of the
extending foreskin can be done by the surgeon by passing a sharp
scalpel along the upper face of the clamping member 16 while
stretching the foreskin with the hemostat. The clamping member is
removed about a minute later and the other steps followed as
previously described. This provides a less costly instrument which
may appeal to some producers, although it does not provide the same
fully disposable instrument and requires sharpening of the scalpel
and autoclaving of same for sterilization between times of use.
While but two forms of the invention have been shown and described,
other forms within the spirit and scope of the invention will now
be apparent to those skilled in the art. Therefore, the embodiments
shown in the drawings are to be considered as merely setting forth
the surgical instrument invention for illustrative purposes, and
are not intended to limit the scope of the invention herein
described, shown and claimed. It is further to be noted that while
directional terms have been used, same are not to be construed as a
limitation of the invention since such use has been availed of to
better describe the invention as used and illustrated in the
drawings.
