ABSTRACT:
In a surgical applicator for U-shaped clips comprising a handle, a tubular shaft adjoining the handle, a forceps-type applicator tool at the free end of the tubular shaft and a clip magazine in the tubular shaft, a closing mechanism arranged in the tubular shaft for the applicator tool, the closing mechanism being actuatable from the handle, and an advancing mechanism arranged in the tubular shaft for the clips, the advancing mechanism likewise being actuatable from the handle and pushing the clips forwards in a path of advance leading into the applicator tool, in order to prevent unintentional pushing-back of the clips in the applicator before the final application, it is proposed that a restraining nose project resiliently between the forceps-type legs of the applicator tool and into the path of advance of the clips, the restraining nose being resiliently displaced by the forwardmost clip out of the path of advance thereof when the forwardmost clip is pushed past into the applying position, and the restraining nose resiliently returning into the path of advance and resting against the rear side of the clip upon arrival of the clip in the applying position.
