ABSTRACT:
A pistol for setting surgical clamps has a clamp magazine disposed at the distal end of a tubular endoscopic shaft, a feeding mechanism for the clamps, and forceps with an associated forceps closing mechanism for setting the clamps. The feeding mechanism and the forceps closing mechanism are operated using a hand grip of the pistol. The clamp magazine has a lower magazine part and an upper magazine part permanently disposed on the lower magazine part. The clamp magazine is insertable over guiding elements into the endoscopic shaft with the feeding mechanism and the clamps are contained in the clamp magazine. The forceps and the forceps closing mechanism are disposed below the clamp magazine with the forceps being exchangeable. The clamp magazine is open at an end facing the grip for introducing a push rod for a feeding slide with the feeding slide having a connecting piece into which the push rod is disposed and locked. An elastic latch locks the clamp magazine in the endoscopic shaft. The forceps closing mechanism has a leading incline engageable with a leading incline on the elastic latch to permit release of the elastic latch simultaneous with displacement of a filler piece on said forceps closing mechanism to permit release of the forceps.
