1. An apparatus for applying surgical clips to body tissue, comprising:

  • a handle portion; and

    a trigger rotatably coupled to the handle portion, the handle portion including;

    a rack slidably supported within the handle portion and in mechanical communication with the trigger, the rack configured to translate from a first, proximal position, to a second, distal position;

    a pawl slidably and rotatably supported within the handle portion, the pawl being in selective engagement with the rack; and

    a biasing element supported by the handle portion and in mechanical communication with the pawl, the biasing element having a biasing force configured to bias the pawl towards the rack such that the rack is permitted to translate in a distal direction, but is selectively inhibited from translating in a proximal direction until the rack is in the second, distal position,wherein actuation of the trigger in a proximal direction causes the rack to translate in a distal direction and actuation of the trigger in a distal direction urges the rack in a proximal direction and causes the pawl to exert a force on the biasing element, wherein when the force exerted on the biasing element is greater than the biasing force, the biasing element deflects allowing the pawl to disengage from the rack and permit the rack to translate in a proximal direction to the first, proximal position.
