Abstract
Abstract A bloodless circumcision clamp having a C-shaped frame comprising two members that are rotatably engaged. A rod goes through a slot in the upper member and an opening in a clamping ring which is located in a lower member. A bell-shaped member on the rod is adapted to receive the glans of a penis and the foreskin goes over the bell. When the clamping element is drawn upward, the bell-shaped member and the opening in the clamping ring are brought into cooperative arrangement, thereby constricting the blood vessels in the foreskin and allowing it to be cut away.
