Surgical instrument and loading unit for use therewith
First Claim
1. A loading unit configured for releasable engagement with a surgical instrument, the loading unit comprising:
- a body portion defining a longitudinal axis, a proximal portion of the body portion configured for releasable engagement with an endoscopic portion of the surgical instrument;
a drive assembly slidingly disposed at least partially within the proximal body portion;
a pair of jaw members extending generally distally from the proximal body portion, each of the jaw members being longitudinally curved with respect to the longitudinal axis, the pair of jaw members including a first jaw member and a second jaw member;
an asymmetrical dynamic clamping member disposed adjacent a distal portion of the drive assembly, the dynamic clamping member including an upper beam, a lower beam, and a vertical beam, the vertical beam connecting the upper beam and the lower beam and including a cutting edge on a distal portion thereof; and
a tissue stop disposed adjacent a distal portion of the first jaw member and configured to impede tissue from distally 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.

16. A loading unit configured for releasable engagement with a surgical instrument, the loading unit comprising:
-
a body portion defining a longitudinal axis, a proximal portion of the body portion configured for releasable engagement with an endoscopic portion of the surgical instrument; a drive assembly slidingly disposed at least partially within the proximal body portion; a pair of jaw members extending generally distally from the proximal body portion, 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 in response to at least partial linear translation of the drive assembly, the pair of jaw members including a first jaw member and a second jaw member; an asymmetrical dynamic clamping member disposed adjacent a distal portion of the drive assembly, wherein the dynamic clamping member includes an upper beam, a lower beam, and a vertical portion, the vertical portion connecting the upper beam and the lower beam; and a tissue stop disposed adjacent a distal portion of the first jaw member and configured to impede tissue from distally escaping the jaw members. - View Dependent Claims (17, 18)
