Patent Images
1. An apparatus for applying surgical staples, which comprises:
- a) a first frame having a proximal end portion and a distal end portion, and including a support connected to a first handle; and
b) a second frame releasably engaged with the first frame, the second frame including an elongated anvil and a bracket fixedly attached to the anvil, a second handle pivotally mounted to the bracket, the anvil having a proximal end portion and a distal end portion, the proximal end portion of the anvil having a trunnion portion which includes two spaced apart walls, each wall having an outward facing surface and a laterally projecting protuberance on a portion of the planar surface, and wherein the anvil includes at least one planar lateral side and the bracket includes at least one planar lateral side parallel to and in flush contact with the planar lateral side of the anvil and fixedly attached thereto.

Abstract
A surgical stapling apparatus includes an anvil having a trunnion with outward facing protuberances. The anvil has planar lateral sides. A mounting bracket for attaching a handle to the anvil has planar lateral sides which are flush against the planar lateral sides of the anvil by and fixedly attached thereto by, for example, a plurality of spot welds.

12. An apparatus for applying surgical staples which comprises:
-
a) a first frame having a proximal end portion and a distal end portion; b) a transverse pin supported at the proximal end portion of the first frame; and c) a second frame removably mountable to the first frame and having a proximal end portion and a distal end portion, the proximal end portion including a pair of spaced apart downwardly extending surfaces, each surface being bifurcated to form a notch to engage the transverse pin, and each surface including a laterally projecting protruberance configured to engage an inner surface of the first frame. - View Dependent Claims (13, 14, 15)
