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.

49. 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; and
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. - View Dependent Claims (50, 51, 52, 53, 54, 55, 56, 57)

58. 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 (59, 60, 61, 62, 63, 64)

65. A method of assembling a surgical fastener applying apparatus comprising the steps of:
-
providing an anvil half-section defining a longitudinal axis and a tissue contacting surface;
providing a cartridge receiving half-section being operatively connectable with the anvil half-section such that a distal end of the anvil half-section is in juxtaposed relation to a distal end of the cartridge receiving half-section;
providing a deflection control system operatively connectable with 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 disposed in the distal end of the anvil half-section; and
connecting the deflection control system with the anvil half-section such that the deflection control system reinforces the distal end of the anvil half-section when a force is applied thereto in a direction transverse to the longitudinal axis defined by the anvil half-section and normal to a plane defined by the tissue contacting surface thereof.
