Apparatus for applying surgical fasteners
First Claim
1. Apparatus for driving surgical fasteners comprising:
- a) a body having a proximal portion and an articulating distal portion;
b) linkage structure extending between said proximal portion and said distal portion of said body and operatively associated with said proximal portion of said body for moving said distal portion relative to a longitudinal axis of said proximal portion;
c) a cartridge assembly mounted adjacent said articulating distal portion and having a tissue engaging surface thereon;
d) an anvil member having a fastener forming surface thereon, said anvil member mounted adjacent said cartridge assembly for relative movement between an open position wherein said fastener forming surface is spaced from said tissue engaging surface and a closed position wherein said fastener forming surface is in close cooperative alignment with said tissue engaging surface;
e) camming means associated with said articulating distal portion for moving said anvil member between said open position and said closed position; and
f) means for ejecting said surgical fasteners from said cartridge assembly to form against said fastener forming surface of said anvil member.

Abstract
Surgical apparatus is provided for placing lateral lines of surgical fasteners into body tissue. The apparatus includes an endoscopic body having an elongated proximal portion and an articulating distal portion which moves relative to the proximal portion. A cartridge assembly and an anvil member are detachably mounted adjacent the articulating distal portion which move relative to one another between an open position and a closed position. A camming mechanism is associated with the articulating portion of the apparatus for moving the anvil member relative to the cartridge assembly, and a linkage system is provided for effectuating the articulation of the distal portion of the endoscopic body to increase the range of operability of the apparatus. In addition, a driving mechanism is provided for ejecting the surgical fasteners from the cartridge assembly.

18. Apparatus for driving surgical fasteners comprising:
-
a) a body having a proximal portion and an articulating distal portion; b) linkage structure extending between said proximal portion and said distal portion of said body and operatively associated with said body for remotely moving said distal portion relative to a longitudinal axis of said proximal portion; c) a cartridge assembly mounted adjacent said articulating distal portion and having a tissue engaging surface thereon; d) an anvil member having a fastener forming surface thereon, said anvil member mounted adjacent said cartridge assembly for relative movement between an open position wherein said fastener forming surface is spaced from said tissue engaging surface and a closed position wherein said fastener forming surface is in close cooperative alignment with said tissue engaging surface; e) camming means associated with said distal portion for moving said anvil member between said open position and said closed position; f) means positioned adjacent a proximal end of said body for remotely moving said camming means between a first position corresponding to said anvil member being in an open position and a second position corresponding to said anvil member being in a closed position; and g) means positioned adjacent a proximal end of said body for remotely ejecting said surgical fasteners from said cartridge assembly to form against said fastener forming surface of said anvil member. - View Dependent Claims (19, 20, 21, 22, 23, 24, 25)
