A surgical clip applier and methods for applying surgical clips to a vessel, duct, shunt, etc., during a surgical procedure are provided. In one exemplary embodiment, a surgical clip applier is provided having a housing with a trigger movably coupled thereto and a shaft extending therefrom with opposed jaws formed on a distal end thereof. The trigger is adapted to advance a clip to position the clip between the jaws, and to move the jaws from an open position to a closed position to crimp the clip positioned therebetween. The surgical clip applier can include a variety of features to facilitate use of the device, including features to align a clip with the jaws, features to prevent unintentional migration of a clip, and features to prevent clip fallout during formation.
What is claimed is: 1. An improved endoscopic surgical clip applier having jaws which close together to approximate tissues to be clipped, a push rod adapted to close the jaws, a trigger adapted to actuate the push rod, and a ratchet mechanism adapted to prevent the trigger from opening during at le
What is claimed is: 1. An improved endoscopic surgical clip applier having jaws which close together to approximate tissues to be clipped, a push rod adapted to close the jaws, a trigger adapted to actuate the push rod, and a ratchet mechanism adapted to prevent the trigger from opening during at least a portion of a closing stroke, the improvement comprising:a preloaded rotary joint formed between the push rod and a linkage coupling the push rod to the trigger, the preloaded rotary joint being effective to maintain the jaws in a substantially fixed partially closed position when the trigger is partially opened during a closing stroke to retain a partially formed clip between the jaws, wherein the preloaded rotary joint includes a biasing element disposed in a recess that includes at least one ridge formed therein configured to maintain the biasing element at a substantially constant load during a closing stroke and up through full closure of the jaws.
