CIRCUMCISION CLAMP Filed Aug. 12, 1960 2 Sheets-Sheet 2 INVENTOR. MARTIN H. CHESTER AGENT United States This invention relates to a circumcision clamp and more particularly to such a clamp especially suitable for use in adult circumcisions.
It is well known to those skilled in the medical art that a correct and effective circumcision operation requires that an adequate amount of prepuce or foreskin be excised. On the other hand, excision of an excessive amount of foreskin or prepuce could result in a painful scar. Additional hazards such as accidental amputation of glans penis and injury to the urethra have been reported in the surgical literature.
Several circumcision clamps are now in use for the so called bloodless circumcision operation. These include the Sheldon Clamp, the Yellen Clamp, the AL AKL Preputome, and the Ross Circumcision Clamp, all of which produce hemostasis by crushing the layers of the prepu ce. These clamps produce the desired results in most infant circumcisions. Their use, however, in adult circumcisions will increase the risk of post operative hemo'rrhage. As noted on page 411 of Surgery for General Practice by Victor Richards published by C. V. Mosby Company, St. Louis, 1956, except in infants the advantages of bloodless type circumcision clamps is more apparent than real.
Consequently, in performing adult circumcisions, most surgeons prefer to use a technique which includes dorsal and ventral slitting of the prepuce followed by excising with circumscribing incisions. Active bleeding from small arteries is controlled by conventional surgical technique, the artery being clamped and a ligature applied.
The device of this invention facilitates and increases the safety of this type of operation. This is accomplished by providing means for clamping the inner and outer layer of the lateral flaps prepuce and means for guiding the scalpel or dissecting scissors. In this manner, the circumscribing incision of the prepuce is greatly facilitated with on optimum excision of skin readily achieved. Using the device of this invention, the operating surgeon can easily make an adequate excision of skin with a sufiicient amount of prepuce being removed to produce the maximum benefits from the circumcision surgery. At the same time, the excision of excessive amounts of the prepuce is prevented so that enough prepuce is available to cover the corona and consequently increase the ease of suturing.
It is therefore an object of this invention to provide an improved circumcision clamp especially suited to adult circumcisions.
It is a further object of this invention to facilitate circumcision operations.

FIG. 5 is a perspective view illustrating how the device of the invention is utilized in a circumcision operation; and
FIG. 6 is a second perspective view illustrating how the device of the invention is utilized in performinga circumcision operation.
Referring now to FIGS. 1 and 3, a plan and aperspective view of a preferred embodiment of the device of the invention are illustrated. The device comprises a first member 12 and a second member 14 mounted pivotally with respect to each other on pivot pin 22. These members are mounted so that they are capable of scissorlike motion about pin 22. Each member has a similar elongated arm 34 and 33 respectively. Attached to each of arms 34 and 33 is a respective finger grip 31 and 30. These finger grips may be integrally formed with their associated arms. Extending from finger grip 30 is a ratcheted piece 28. A similar ratcheted piece 27 extends from finger grip 31. Ratcheted pieces 27 and 28 are positioned so that they will mate with each other when finger grips 3i? and 31 are drawn together to lock members 12 and 14 in clamping engagement. FIGS. 1 and 2 show members 12 and 14 in such clamping engagement.
Referring now to FIG. 4, in addition to FIGS. 1 and 3, the details of the holding and guiding portions of members 12 and 14 are shown. A holding member 29 is fixedly attached to arm 33 and pivotally mounted on Holding member29 comprises a support portion 35, a pair of forked arms 37 and 38 extending therefrom, and a curved holding plate 16 attached to forked arms 37 and 38. Plate 16 has serrations 19 on It is still a further object of this invention to lessen the hazards attendant to circumcision operations.
It is another object of this invention to lessen the time required for circumcision operations.
It is still another object of this invention to enable an operating surgeon in a circumcision operation to easily excise an optimum amount of skin with smooth even incisions.
Other objects of the invention will become apparent as the description proceeds in connection with the accompanying drawings in which:
FIG. 1 is a plan view of a preferred embodiment of the device of the invention; i
' FIG. 2 is a cross-sectional view of the embodiment illustrated in FIG. 1 taken along a plane as indicated by the line 22 in FIG. 1;
the inner curved surface thereof.
A guide member 32 is fixedly attached to arm 34 and pivotally mounted on pivot pin 22. Guide member 32 has an elongated aperture 39 therein through which holding member 29 fits and is free to, pivot relative to .guide member 32. Guide member 32 includes a support portion 36, and a curved guide plate 15 attached thereto. Guide plate 15 has a serrated portion 20 on the outer curved surface thereof. The curvature of plate 15 must be similar to that of plate 16 so that the two plates will mate with each other when finger grips 3d and 31 are drawn together. This mating relationship is indicated in FIGS. 1 and 2 which shows plates 15 and 16 drawn together with serrated surface 19 mating with serrated portion 20 of the top surface of plate 15.
Plate 15 has a groove 18 in its outer circumferential surface running substantially parallel to the extreme edge of this plate. When plates 15 and 16 are drawn together, groove 18 is positioned adjacent to the extreme edge 41 of plate 16. The curvature of groove 18 and the extreme edge 41 of plate 16 approximates the curvature of one-half the corona of the human penis starting at the frenulum. The operation, as to be explained further on in the specification, is performed with a matched pair of circumcision clamps, one of these clamps having a plate 15 with a groove 18 and a plate 16 with an edge 41 having a curvature to match the shape of the corona of the penis on one side of the frenulurn, the other of these clamps having such portions to match the shape of the corona on the other side of the frenulum. The device of the invention may be made with plates 15 and 16 of various sizes and curvatures to accommodate individual physical differences in patients.
Referring now to FIGS. 5 and 6, the use of the device of the invention in performing a circumcision operation is illustrated. Prior to the application of the clamps of the device of the invention, the glans andlayers of the prepuce are prepared in the standard manner. Adhesions between the. glans and prepuce are freed and a dorsal and ventral slit is made by cutting between conventional surgical clamps. Theventral 'slit is made in a line with the fre'uulum while the dorsal slit is made directly opposite this. This produces two lateral flaps of the prepuce. The surgeon now applies the clamps of the device of the invention as shown in FIGS. and 6. A pair of clamps,
one to hold the right lateral flap 45 and the other to hold the left lateral flap 46 is used. Each of these clamps should have a plate 16 with an edge portion 41 and a plate 15 with a groove 18 (see FIG. 4) having a curvature to match the'associated left or right hand portion of the corona, as already noted. In inserting each lateral flap in its respective clamp, curved guide Plate 15 is placed lateral to the glans with the clamp opened. The lateral flap is then pulled over this guide plate with care being taken not to produce undue tension on the prepuce. With the lateral flap placed in position on guide plate 15, the clamp is closed, and the inner and outer layers of the prepuce are fixedly held between serrated surfaces 19 and 20. Care must be taken not to injure the frenulum in this step. A scalpel 50 may then be used to excise the foreskin, the edge 41 of holding plate 16 and the groove 18 in guide plate 15 (see FIGS.
1, 3, and 4) being used as guides. The scalpel will be guided by the contours of edge 41 and groove 18 to make it relatively easy toaccomplish a smooth even incision. After the incision has been completed, the bleeding points are clamped with standard surgical clamps, and the wound is closed in accordance with standard surgical technique. It so desired, dissecting scissors may be used in place of a scalpel for making the incision.
It is readily noted that the guide plate 15 of the device of the invention functions as measuring means so that a constant and sufiicient amount of prepuce will be excised from the right and left lateral flaps. guide plate 15 serves to protect the glans and urethra from injury by the dissecting instrument. Furthermore, the curvature of the guide plate is such as to enable the operator to easily avoid cutting the frenulumand the frenular artery which is a common source of post operative bleeding.
The device of the invention, as can be seen, greatly facilitates a circumcision operation and considerably lessens the hazards attendant thereto. A smooth ideal excision of the prepuce'is made readily achievable. Post operative complications such as urethral fistula, lacerations or amputation of the glans, lacerations or amputation of the urethral meatus, and partial removal of the prepuce are readily avoided. At the same time, excessive removal ofthe prepuce is prevented, thereby avoiding residual painful scars.
While the device of the invention has been explained and illustrated in detail, it is to be clearly understood that this is intended by way of illustration and example only, the scope of the invention being limited only by the terms of the appended claims.
