L. C. DWOYER SURGICAL INSTRUMENT Filed Dec. 7, 1942 INVENTOR. (I DWQYER Patented Aug. 8, 1944 v OFFICE SURGICAL INSTRUMENT Leon 0. Dwoyer, Linden, NJ. Application December 7, 1942, Serial No. 468,031

. 3 Claims. (01. 128-346) The present inventionrelates to improvements in surgical instruments and more particularly to improvements for use in performing circumcisions.

An object of my invention is to provide a novel circumcision instrument which is of simple and durable design and is easily manipulated.

Another object of my invention is to provide a novel circumcision instrument which will apply a firm clamping pressure to an intended circumferential area of the prepuce, thus xpediting the labor of the surgeon and yet will not subject the prepuce to a rupturing action.

Another object of my invention is to provide a surgical instrument wherein the prepuce is held in a position for operation in such a manner that there will be no appreciable loss of blood by the severing of the prepuce.

Another object of my invention is to provide a surgical instrument which can be locked in any desired position, thus facilitating the handling of the device and hence the operation.

Other objects and advantages of my invention will be hereinafter described and the novel features thereof defined by the appended claims.

In the accompanying drawing an embodiment of my invention is shown.

Fig. 1 is an elevational side View of a surgical instrument according tomy invention for use in performing circumcisions.

Fig. 2 is a plan view of the instrument of Fig. 1.

Fig. 3 is a longitudinal section of a part of a surgical instrument according to Fig. 1 on an enlarged scale; and

Fig. 4 is a longitudinal section of a part of a surgical instrument according to Fig, 1 illustrating the position of the various members when applying a clamping pressure to the prepuce.

With reference to the drawing, wherein like reference characters indicate like parts throughout the several figures thereof, my device comprises an arm I in which a circular opening It is formed. The opening II is provided with a frusto-conical wall I2 which constitutes a clamping edge or seat. Arm I0 may be made of any suitable material, for example, metal, plastic or the like. A lever or member I3 is pivotally connected to arm II] by means of a pivot I4. Member I3 carries a stem I5 which may be integral with member I3 or be secured to it by any suitable means. Stem I5 serves as carrier for a cupshaped clamping portion I6 which may be hollow as shown in Fig. 4. The lower end of cup I B may be formed as the frustrum of a cone and sets through opening II andis arched to form a section of the .periphery of alcircle drawn about pivot point I4; I hereby accomplish that lever I3 will pull clamping portion I6 supported by stem I5 in such direction as to draw the clamping portion evenly toward the clamping seat when lever I3 is pivoted around pivot I 4.

In order to pivot the arm I0, I have provided a scissor type handle I1 ending in a loop I8 for receiving the digits of the hand and a second scissor type handle IS'ending in a loop 20. Handle I1 is integral with arm I0 but, of course, it is also possible to provide a separate handle fastened by any suitable means to arm [0. Handle I 9 is integral with lever I3 but a separate handle secured to the lever may be used. It is obvious from the drawing that handles IT and I9 cooperate in such a manner that a relative movement of those handles will cause clamping portion I6 to move toward its clamping edge or away from it, depending upon whether handles I! and I9 are moved outwardly or inwardly. Due to the arched shape of stem l5, clamping portion I ii will sit evenly upon its clamping seat when the surgical device is closed as illustrated in Fig. 4.

Handle I! is provided with an extension 2| having several notches 22. These notches 22 cooperate with a nose 23 provided on an extension 24 of handle I9. Notches 22 and nose 23 serve to lock the handles I I and I9 and hence the clamping portion of the device in any desired position. I have found that such locking means facilitate the labor of the surgeon and thus shorten the period of pain and inconvenience of the patient caused by the operation.

A surgical device according to my invention is to be used as follows:

The prepuce as shown in dotted lines in Figures 3 and 4 is slipped over a cup I6 while the glans penis (not shown) is resting in the cup. Then the clamping device is gently closed whereby the prepuce is pulled toward the clamping seat until finally a circumferential area of the prepuce is firmly and uniformly held between the walls I2 of the opening 5 I and clamping portion I 6 as illustrated in Fig. 4. The prepuce is now in a position in which the operation can be conveniently carried out.

The invention may be embodied in other specific forms without departing from the spirit of the invention or the essential characteristics thereof. The present embodiment is to be considered in all respects as illustrative and not restrictive, the scope of the invention being indiinto clamping seats II and I2. stem I5 extends cated by the appended claims.

What is claimed to be desired and secured by Letters Patent is:

1. In a surgical instrument for use in performing circumcisions, in combination an arm having an opening providing a clamping seat, a clamping element extending through said opening and having a portion cooperating with said clamping seat for applying a clamping pressure to a circumferential area of the prepuce and means for pulling said clamping element in such a direction as to draw the clamping portions thereof evenly toward said clamping seat, said means comprising a member pivotally c-onnectedto said arm having said clamping seat and carrying said clamping element and a handle for pivoting-said member about its pivot point.

2. In a surgical instrument for use "in performing circumcisions, in combination an am having an opening providing a clamping seat, a member pivotally connected to said arm having said clamping seat a clamping element having a portion cooperating with said clamping seat and a stem extending through the opening of said arm, one end of said stem being fastened to said portion and the other to said member and a handle for pivoting said member about its pivot point thus pulling said clamping element in such direction as to draw the clamping portion thereof evenly toward said clamping seat.

3. In a surgical instrument for use in performing circumcisions, in combination an arm having an opening providing a clamping seat, a member pivotally connected to said arm having said clamping seat, a clamping element having a portion cooperating with said clamping seat and an arched stem extending through said opening of said arm, one end of said arched stem being fastened to said portion and the other to said member, a scissor-type handle fastened to said member and a second scissor-type handle cooperating with said first handle fastened to said arm for pivoting said member about its pivot point thus pulling said clamping element in such direction as to draw the clamping portion thereof evenly toward said clamping seat.
