<p>An endoscopic clip applier (10) for the temporary as well as permanent occlusion of vessels and the clipping of other tissues. The clip applier (10) includes an elongated outer body (12) having a proximal (14) end attached to an actuating mechanism (16) and a distal end (18). An elongated inner member (50) is slidably positioned within the outer body and has a proximal end (52) coupled to the actuating mechanism and a distal (54) end coupled to a pair of generally opposing jaws (30). Movement of the inner member relative to the outer body pivots the jaws open and closed. The jaws are configured for receiving and supporting a malleable surgical clip (24) which is insertable within the internal retention groove (36) of each jaw (30). Each groove has an undercut portion (40) at its distal end which is configured to mate with an outwardly tapering portion at the distal end of each clip. The clip is forced distally into the grooves, the distal ends of the clip are moved into the undercut portion, and the clip is retained within the groove.</p> |
