Abstract
Abstract Surgical instruments, particularly rectal hemo-clip applicators have a handle consisting of two parts which are interconnected pivotally and resiliently. The two handle parts are connected to two elongated members located one within the other and movable relatively to each other when the handle is actuated. The outer ends of the two members have jaws which are movable toward and away from each other to carry out surgical operations.
