Abstract

A disposable ligator for applying clamping clips to veins, arteries and blood vessels. The ligator comprises a first handle terminating at its forward end in a first jaw and a second jaw and a second handle, both pivotally mounted on the first handle near the forward end thereof. The handles are shiftable between open and closed positions and shift the jaws between open and closed clip-clamping positions. A clip tube containing a plurality of clips and a spring biased feeder shoe to constantly urge the clips forwardly therein is mounted in the first handle. A pusher is mounted in the first handle parallel to the clip tube in a pusher track which extends to the forward ends of the jaws. The pusher is shiftable by the first and second handles between a retracted position when the handles are closed and an extended position to locate a clip in the pusher track at the forward ends of the jaws when the handles are open. The first handle provides a ramp structure leading to the pusher track at the forward end of the clip tube which is covered by the pusher when in its extended position and exposed by the pusher when in its retracted position, thus enabling the forwardmost clip to be transferred to the pusher track in front of the pusher due to the forward urging of the clips in the clip tube, and without the necessity of moving transfer parts.
