Abstract
A surgical instrument comprises an elongated body provided with a hand lever. At a distal end of said body there is secured a female die having a pit for bending the legs of staples. A clamping jaw provided with a driver for inserting staples is mounted on said body for reciprocating travel in the direction of said female die. Within the clamping jaw there is provided a passage for feeding a wire, and on the clamping jaw there is mounted a knife capable of reciprocating in the direction perpendicular to the outlet end of the conduit, and adapted for cutting wire lengths. On the body there is also mounted a device for forming staples from wire lengths.
