Abstract
Abstract Apparatus (10) is disclosed for applying two-part surgical fasteners during endoscopic or laparoscopic procedures. The apparatus includes a handle assembly (12), an endoscopic portion (16) which extends from the handle assembly, and a tool assembly (18) pivotally associated with a distal end of the endoscopic portion for applying a two-part surgical fastener. A mechanism is provided for effectuating articulated pivotal movement of the fastener applying tool assembly within an angular sector of rotation to increase the operational range of the instrument.
