Abstract
Abstract A surgical device is described herein that can be used to fire different types and sizes of disposable loading units. In a preferred embodiment, the device applies parallel rows of surgical fasteners to body tissue and concomitantly forms an incision between the rows of staples during an endoscopic or laparoscopic surgical procedure. The device can be utilized with disposable loading units configured to apply linear rows of staples measuring from about 15 mm in length to about 60 mm in length and can be used to fire disposable loading units containing surgical clips and individual staples.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
198 words
A surgical device comprising: a handle assembly including a manually actuated pivotable handle mounted for manipulation through an actuating stroke; an elongated body extending distally from the handle assembly and defining a longitudinal axis; an actuation member supported within the handle assembly and mechanically coupled with the pivotable handle during the actuating stroke, the actuation member being mounted for linear movement in response to manipulation of the movable handle through the actuating stroke; a tool assembly supported on the distal end of the elongated body, the tool assembly including a first jaw and a second jaw, the second jaw having a proximal end defining a cam surface and being pivotal in relation to the first jaw from an open position to a closed position; and a drive member secured to a distal end of the actuation member, a distal end of the drive member supporting a knife blade and a cam member; wherein the cam member is positioned to engage the cam surface of the second jaw and translate along the cam surface of the second jaw to move the first and second jaws from the open position to the closed position and to progressively clamp body tissue.
