Apparatus for applying surgical clips
First Claim
1. An apparatus for application of surgical clips to body tissue, which comprises:
- a) a handle assembly;
b) an elongated body portion extending distally from the handle assembly;
c) a jaw assembly mounted at a distal end portion of the elongated body portion, the jaw assembly including first and second jaws movable between an open position and a closed position;
d) an actuator slidable within the elongated body portion in response to actuation of the handle assembly, the actuator having camming structure at a distal portion thereof for moving the first and second jaws between the open position and the closed position; and
e) a loading unit releasably mounted to the elongated body portion and storing a plurality of surgical clips therein;
the loading unit including;
i) a clip advancer having a portion engageable with the actuator and movable therewith for advancing a distalmost surgical clip; and
ii) a ratchet assembly positioned adjacent to the clip advancer, the ratchet assembly being in operative engagement with the clip advancer to index progressive movement thereof.

Abstract
An apparatus for application of surgical clips to body tissue is disclosed having a handle assembly and an elongated body portion extending distally from the handle assembly. A jaw assembly is mounted at a distal end portion of the elongated body portion and includes first and second jaws movable between an open position and a closed position. An actuator is disclosed which is slidable within the elongated body portion in response to actuation of the handle assembly. The actuator has camming structure at a distal portion thereof for moving the first and second jaws between the open position and the closed position. A loading unit is releasably mounted to the elongated body portion and stores a plurality of surgical clips therein. The loading unit includes a clip advancer having a portion engageable with the actuator and movable therewith for advancing a distalmost surgical clip and a ratchet assembly associated with the clip advancer to index progressive movement thereof.
