Articulating apparatus for applying surgical fasteners to body tissue
First Claim
1. An apparatus for applying a plurality of surgical fasteners to body tissue comprising:
- a) a handle assembly;
b) an elongated body extending from the handle assembly and defining a longitudinal axis;
c) a cartridge housing pivotably connected to a distal end portion of the elongated body;
d) a fastener cartridge containing a plurality of surgical fasteners and positionable in the cartridge housing;
e) an anvil pivotally mounted adjacent relative to the cartridge housing and defining a fastener forming surface against which surgical fasteners are driven when ejected from the fastener cartridge, the anvil being pivotable relative to the cartridge housing between a first position in longitudinal alignment with the cartridge housing and a second position skewed relative to a longitudinal axis of the cartridge housing;
f) a fastener driving mechanism operatively associated with the fastener cartridge and actuatable from the handle assembly to eject fasteners from the fastener cartridge;
g) a single rod link member in direct operative association with the cartridge housing, which pivotably moves the cartridge housing between a first position in alignment with the longitudinal axis of the elongated body, and a second position out of alignment with the elongated body longitudinal axis; and
h) a pivotable control lever in direct operative association with the single rod link member and pivotable between a position corresponding to the first position of the cartridge housing and a position corresponding to the second position of the cartridge housing, the relative pivotable position of the control lever providing visual indication of the position of the cartridge housing relative to the elongated body.

Abstract
Apparatus for applying a plurality of surgical fasteners to body tissue includes an elongated body extending from a handle assembly. A fastener cartridge housing pivotably connected to a distal portion of the elongated body receives a fastener cartridge containing a plurality of surgical fasteners. A fastener driving mechanism actuatable from the handle assembly ejects fasteners from the fastener cartridge to form them against an anvil mounted adjacent the cartridge housing. The fastener cartridge is pivotably movable from a position in alignment with a longitudinal axis of the elongated body to a position out of alignment with the elongated body. Visual indication of the relative position of the fastener cartridge is provided by a control lever which is movable toward and away from the handle assembly to correspond with movement of the fastener cartridge. A clamp mechanism is also provided to move the anvil relative to the cartridge housing to clamp tissue therebetween.
