Abstract
A jaw mechanism for an endoscopic instrument is provided. The mechanism includes a drive rod having at least one boss radially protruding from a distal portion of the drive rod. A portion of the jaw mechanism has at least one groove that slidingly engages the at least one boss. A proximal portion of the drive rod is adapted to interface with an actuation mechanism. When actuated, the drive rod moves axially through a tubular member. The at least one boss travels through the at least one groove, causing the jaw mechanism to pivot around a pivot point connected to the distal portion of the tubular member.
