摘要
A clip pusher and stop system for a surgical ligator has first and second clip-clamping jaws (3,5), a pair of handles (2,4) to actuate the jaws, a magazine of ligating clips, (8) a pusher track, (7) extending to the forward ends of the jaws, a pusher. (6) to transfer a clip along the pusher track from the magazine to a forward position between the jaws, and a stop, (17) to prevent rearward movement of the clip in the pusher track during the clip-applying and clamping procedure. The stop comprises a substantially L-shaped resilient member having a long leg (18) and a short leg (19). The long stop leg lies along a depression (20) in the first jaw (3) and affixed (24), near its free end to the first jaw. (3) The short leg, (19) extends between the first and second jaws and is receivable in a perforation, (28) in the second jaw when the jaws are actuated to clamp a clip. The short leg has an intermediate clip-contacting portion, (19d) normally extending across the pusher track. The clip-contacting portion is shiftable by an advancing clip out of the pusher track, and returns into the pusher track behind a fully advanced clip to prevent rearward movement of the clip during the clip-applying and clamping procedure and to dislodge the clip from the pusher if adhered thereto by body fluids or the like.
