  • Patent number: 5439468
    Abstract: The rod system consists of an outer guide tube in which there is arranged an inner sliding sleeve, displaceable coaxially to the outer guide tube, in which are located an elongated support rod fixed relative to the outer guide tube an elongated slide displaceable on the support rod. The holding and shaping mechanism comprised by sliding sleeve, support rod and slide, project from the distal end of the outer guide tube in a manner guaranteeing the holding and shaping function of the clip or staple applying apparatus. After the distal end of the slide, designed as a tip, has struck the anvil, it displaces the sliding sleeve in the same direction beyond the distal end of the support rod and of the slide. The sliding sleeve and the slide return to the starting position in the proximal direction upon release of the actuating lever.
