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.

Claims26

Dependent claims

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.

3 more elements

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.
