the clamp includes a passage adjacent to a pivot connection and into which a corresponding pivot pin is at least partially displaced from its original position into a position in which the circumcision clamp becomes inoperative . in one embodiment , the passage is located at one end of the latching member having a notch that is adjacent to a spur so that , when the clamp is moved to a closed position , the spur slips into the notch . the spur and notch resist movement of the latching member thereby causing the pivot pin to be forcibly displaced from its original position into an inoperative position . select elements of the clamp may be formed of transparent plastic material for allowing a circumcision operator to monitor the glans penis therebeneath so that same is not damaged during a circumcision . alternately , the clamp may be formed of aluminum and stainless steel . in such an embodiment , the passage is located at one end of the handle . as the handle moves to an open position from a closed position , the corresponding pivot pin at the end of the handle is forcibly displaced at least partially into the passage and thereby rendering the clamp inoperative . such an embodiment of the clamp may be sent back to the manufacturer to be refurbished and resterilized for reuse .
