Surgical instrument having an asymmetric dynamic clamping member
First Claim
1. A surgical instrument for surgically joining tissue comprising:
- a handle assembly including a movable handle;
a drive assembly disposed in mechanical cooperation with the movable handle;
an endoscopic portion extending distally from the handle assembly and defining a first longitudinal axis;
a pair of jaw members disposed adjacent a distal end of the endoscopic portion and extending generally distally therefrom, each of the jaw members being curved with respect to the first longitudinal axis, at least one of the jaw members being movable with respect to the other between an open position and an approximated position for engaging body tissue therebetween, the pair of jaw members including a first jaw member and a second jaw member;
an asymmetrical dynamic clamping member disposed in mechanical cooperation with a distal portion of the drive assembly, wherein the dynamic clamping member is advanced distally through at least a portion of the length of the jaw members in response to at least a partial actuation of the movable handle, the dynamic clamping member including an upper beam, a lower beam, and a vertical portion, the vertical portion connecting the upper beam and the lower beam and including a cutting edge; and
a tissue stop disposed adjacent a distal portion of the first jaw member and configured to impede tissue from escaping the jaw members.

Abstract
A surgical instrument is disclosed. The surgical instrument includes a handle assembly, a drive assembly, an endoscopic portion, a pair of jaw members, a dynamic clamping member, and a tissue stop. The drive assembly is disposed in mechanical cooperation with a movable handle of the handle assembly. The endoscopic portion defines a first longitudinal axis. The jaw members are each longitudinally curved with respect to the longitudinal axis. The dynamic clamping member is disposed in mechanical cooperation with a distal portion of the drive assembly and includes an upper beam, a lower beam, and a vertical beam having a cutting edge on a distal portion thereof. At least a portion of the dynamic clamping member is longitudinally curved with respect to the longitudinal axis. The tissue stop is disposed adjacent a distal portion of the first jaw member and configured to impede tissue from distally escaping the jaw members.
