1. A surgical fastener applying apparatus, comprising:
- an anvil half-section defining a longitudinal axis and a tissue contacting surface, the anvil half-section including a distal end, a proximal end, and side walls having a height;
a cartridge receiving half-section including a distal end, the cartridge receiving half-section being operatively couplable with the anvil half-section such that the distal end of the anvil half-section is in juxtaposed relation to the distal end of the cartridge receiving half-section;
a deflection control system operatively associated with the anvil half-section, wherein the deflection control system reinforces the distal end of the anvil half-section when a force is applied to the distal end of the anvil half-section in a direction transverse to the longitudinal axis and normal to a plane defined by the tissue contacting surface of the anvil half-section, a proximal end of the deflection control system extending proximally to at least a pivot point for the anvil half-section and the cartridge receiving half-section, the deflection control system including at least one reinforcing member defining a height and being disposed in the distal end of the anvil half-section, the reinforcing member including a plurality of plates each defining a thickness wherein the thickness of at least one of the plurality of plates is different from the thickness of at least one other plate; and
a pair of juxtaposed shoulders each extending from an inner surface of the side walls of the anvil half-section at the distal end thereof, each shoulder including a body portion defining a height that is different from the height of the at least one reinforcing member.

Abstract
A surgical fastener applying apparatus including an anvil half-section having a distal end and a longitudinal axis; a cartridge receiving half-section having a distal end and operatively couplable with the anvil half-section such that the distal ends of the half-sections are in juxtaposed relation; and a deflection control system operatively engaged with and reinforcing the distal end of the anvil half-section when a force is applied to the distal end of the anvil half-section in a direction transverse to the longitudinal axis.

5. A surgical fastener applying apparatus, comprising:
-
an anvil half-section defining a tissue contacting surface, the anvil half-section including a distal end, a proximal end that defines a longitudinal axis, and an anvil half-section channel member defining a length and having a substantially U-shaped configuration, the channel member including a first pair of side walls interconnected by a first base wall; a cartridge receiving half-section including a distal end, the cartridge receiving half-section being operatively couplable with the anvil half-section such that the distal end of the anvil half-section is in juxtaposed relation to the distal end of the cartridge receiving half-section; and a deflection control system operatively associated with the anvil half-section channel member, the deflection control system including a channel section having a substantially U-shaped configuration and including a second pair of side walls defining a length and being interconnected by a second base wall, the first pair of side walls of the anvil half-section and the second pair of side walls defining a reveal having a height therebetween, a proximal end of the deflection control system extending proximally to at least a pivot point for the anvil half-section and the cartridge receiving half-section. - View Dependent Claims (6, 7, 8, 9, 10, 11)
