An apparatus 10 is provided for applying surgical clips which includes provisions for applying a partially closed clip to ducts or shunts during a surgical procedure such as cholecystectomy procedures. The apparatus includes means 40 for effecting a partial closing stroke of the handle mechanism to correspond to a partial closure of the jaw members, and permits a partial opening stroke to release the partially closed clip in the jaw mechanism. Other features of the invention include means 156 for preventing over-advancement of a clip to the jaw mechanism, means 60 for cradling the clip as it is advanced from the clip supply to the jaw mechanism, means 74 for preventing splaying of the jaws in the event of a clip-over-clip application, and a novel rotation collar 22. The instrument of the present invention provides the surgeon with visual, audible, and tactile indication of the positioning of the jaw members to effect the application of a partially closed clip.
