<p>A Clip-inducing apparatus for omega clips (12), in particular for laparoscopic operations, consists of a tube-like rod system (1) at whose proximal end an operating device (2) and at whose distal end a clip-holding and clip-shaping mechanism are provided. The rod system (1) comprises an outer guide tube (16) in which there is arranged an inner sliding sleeve (17), displaceable coaxially to the outer guide tube (16), in which are located an elongated support rod (18) fixed relative to the outer guide tube (16) and an elongated slide (19) displaceable on the support rod (18). The proximal end of the outer guide tube (16) is firmly connected to the handle (3) of the operating device (2). The movable actuating lever (5) of the operating device (2) is in operational connection with the slide (19) and the sliding sleeve (17) at their proximal ends in such a way that, firstly, the sliding sleeve (17) and the slide (19) running ahead of the sliding sleeve (17) are displaced in the direction of the distal end, designed as an anvil (27), of the fixed support rod (18) and that, after the distal end of the slide (19), designed as a tip, has struck the anvil (27), a displacement of the sliding sleeve (17) in the same direction beyond the distal end of the support rod (18) and of the slide (19) is executed. <IMAGE> <IMAGE></p> |
