Abstract

A circumcision instrument includes a pair of body members displaceable toward each other to simultaneously cut the foreskin along a longitudinal or circumferential line of cut while simultaneously stapling together the skin and mucous layers of the foreskin along at least one stapling line generally parallel with the cut, thereby to reduce bleeding from a cut. In a first embodiment, a generally straight cutting blade is carried by a body member at one end of a pair of scissors-type arms for longitudinally cutting the foreskin, cooperating male and female staple members being removably mounted on opposed body members for simultaneously producing stapling lines on both sides of the cut. In a second embodiment, a pair of annular body members arranged concentrically about a penis are displaced together on opposite sides of the foreskin when folded concentrically back around one of the annular members, a circular stapling line being defined concentrically between a circular cut and the penis. In a third embodiment, a cutting blade is arranged on a body member at one end of an arm of a scissors-type device for intermittently snipping and simultaneously stapling the foreskin along a line extending circumferentially of the penis.

Claims

1. A circumcision instrument for use during the removal of the foreskin from the penis of a patient, said foreskin including an outer layer of skin, and a mucous membrane inner layer intermediate the skin layer and the penis, comprising:

(a) first and second body members adapted for arrangement on opposite sides of the foreskin;

(b) means for displacing said body members alternately toward and away from each other, respectively; and

(c) means carried by said body members and operable when said body members are displaced together for simultaneously cutting the foreskin to define a line of cut and stapling together the mucous membrane and skinlayers of the foreskin adjacent said line of cut, thereby to reduce bleeding from the cut,

(1) said cutting means including a knife blade mounted on said first body member adjacent said second body member;

(2) said stapling means including a plurality of male staple members removably carried by at least one of said body members, said staple members including straight parallel pointed arms extending toward the other body member, and a plurality of cooperating female staple members at least some of which are carried by said other body member opposite said male staple members, respectively, said female members being generally inperforate and being formed of a synthetic plastic material having such a coefficient of hardness as to permit initial penetration thereof by the pointed extremities of said arms without bending of the arms, and subsequent retention of the unbent pointed arms to clamp together the male and female members on opposite sides of the foreskin.

2. Apparatus as defined in claim 1, wherein said knife blade has a straight cutting edge.

3. Apparatus as defined in claim 1, wherein said knife blade has a curved cutting edge.

4. Apparatus as defined in claim 1, wherein said body members are annular, colinearly arranged, and contain a central opening for receiving a penis to be circumcised, said knife blade being generally circular, whereby when the foreskin is longitudinally cut and rolled back concentrically about the outer circumferential surface of said second body member, displacement of said body members together causes the foreskin to be cut and stapled along concentric lines of cut and stapling, respectively, circumferentially of the penis.

5. Apparatus as defined in claim 4, wherein each of said body members includes a pair of hingedly connected longitudinally divided sections, the sections of one of said body members having end faces adjacent corresponding end faces of the sections of the other body member, respectively, and further wherein said knife blade includes a pair of generally semi-circular cutting edges arranged on the end faces of the sections of the first body member adjacent the corresponding section end faces of said second body member, said cutting edges defining a circular cutting line concentrically arranged about said central openings.

6. Apparatus as defined in claim 5, and further including means on each of said body members for fastening together the associated body sections.

7. Apparatus as defined in claim 5, wherein said staple means includes a plurality of said cooperating male and female staple members arranged on said adjacent end faces of said body member sections to define a circular stapling pattern concentrically within said cutting edges.

8. Apparatus as defined in claim 1, wherein said second body member contains a groove for receiving said knife blade.

9. Apparatus as defined in claim 1, wherein said scissors each of said male staple members includes a synthetic plastic support block, and at least one U-shaped metal staple having a transverse portion connected with said support block, and a pair of parallel arm portions that define said pointed arms.

10. Apparatus as defined in claim 9, wherein said body members include parallel adjacent faces containing opposed recesses for receiving cooperating male and female staple members, respectively.

11. Apparatus as defined in claim 9, wherein said body members include parallel adjacent faces containing opposed recesses, and further including cartridge members removably mounted in said recesses, said cartridge members containing recesses for removably receiving said male and female staple members, respectively.

12. Apparatus as defined in claim 1, wherein said body member displacing means comprises scissors means including a pair of scissors arms, said body members being mounted on corresponding first ends of said scissors arms, respectively, and finger-receiving portions at the other ends of said scissors arms, respectively, said arms being pivotally connected intermediate their ends.

13. Apparatus as defined in claim 12, wherein said members are arranged generally longitudinally of said scissors arms, respectively.

14. Apparatus as defined in claim 13, wherein said knife blade has a generally straight cutting edge extending generally longitudinally of the associated scissors arm for cutting the foreskin longitudinally.

15. Apparatus as defined in claim 14, wherein said stapling means defined lines of stapling on opposite sides of, and parallel with, the line of cut of said knife blade.

16. Apparatus as defined in claim 12, wherein said body members are generally parallel and are arranged at an angle relative to the associated scissors arms, respectively.

17. Apparatus as defined in claim 12, wherein said knife blade has a curved cutting edge, thereby to permit circumferential cutting and stapling of the foreskin adjacent the penis.

18. Apparatus as defined in claim 12 wherein said body members are annular, colinearly arranged, and contain aligned central openings for receiving the penis.

19. Apparatus as defined in claim 18, wherein said body member displacing means includes screw thread means.

20. Apparatus as defined in claim 19, and further including guide means guiding said body member for displacement toward and away from each other.

21. Apparatus as defined in claim 20, wherein said guide means includes a pair of parallel spaced guide rods upon which said second body member is slidably guided, and further wherein said screw thread means includes displacing nuts threadably connected with said guide rods, respectively.

22. Stapling means for reducing the bleeding from cut skin, such as a cut foreskin during the circumcision of a penis, which foreskin has a mucous membrane layer and a skin layer, comprising:

(a) a male staple member adapted for arrangement on one side of the foreskin, said male member including a synthetic plastic support block, and a generally U-shaped metal staple including a transverse portion connected with said support block, and a pair of parallel pointed arm portions that are adapted to extend toward the foreskin; and

(b) a female staple member adapted for arrangement on the other side of the foreskin from said male member, said female staple member comprising a generally imperforate synthetic plastic block having a coefficiency of hardness such as to permit penetration thereof by the pointed arm portion of said male staple members without bending thereof as said male and female staple members are displaced together to cause said staple arm portion to pierce the foreskin, said female plastic block being operable to retain said staple arm portion to clamp said blocks together on opposite sides of the foreskin, thereby to clamp together the mucous membrane and skin layers to prevent bleeding from the cut foreskin.

23. Apparatus as defined in claim 22, and further including a plurality of cartridge means supporting a plurality of said male and female staple members to define a given line of stapling, each of said cartridge means being adapted for mounting within a corresponding recess contained in the face of a circumcision instrument body member.

24. Apparatus as defined in claim 23, wherein said cartridge means includes a cartridge body containing a plurality of openings within which said staple members are removably supported, respectively.

25. Apparatus as defined in claim 22, and further including first and second body members carrying said male and female staple members opposite each other, respectively, and means for displacing said body members toward and away from each other, respectively.

26. Apparatus as defined in claim 25, and further including cutting means mounted on said first body member adjacent said second body member.
