ABSTRACT:
A ligating clip is provided with first and second legs joined at their proximal ends by a hinge and terminating at their distal ends by a latch means for holding the clip latched closed when the legs are squeezed together. One of the legs is provided with a base defining guide means for engaging portions of an instrument that may be used to apply the clip. An instrument is provided to apply the clip and includes first and second handles mounted together for pivotal movement. Each handle extends beyond the pivot axis to form a clip closing jaw. The first handle includes a guideway for receiving a plurality of the open clips. A pusher member is provided within the first handle to push the clips to the jaw region. A spool is mounted for rotation in the first handle jaw and includes a forward flange and a rearward flange between which the front clip of the row of clips may be positioned. An L-shaped rod extends from the spool and is pivoted in one direction by one of the handles when the handles are closed to rotate the spool to permit passage of the closed clip from the jaws after the jaws are subsequently partially opened. The rod is also pivoted in a second, opposite direction after the handles are partially opened to orient the spool to block feeding of the next clip beyond the jaw region.
