Surgical fastening apparatus with alignment pin
First Claim
1. A surgical apparatus for sequentially applying a plurality of surgical fasteners to body tissue, which comprises:
- a) holding means for holding a plurality of surgical fasteners in at least two parallel rows oriented along a lengthwise axis of the apparatus;
b) anvil means for closing said fasteners;
c) drive means movable along said lengthwise axis of the apparatus between a proximal position and a distal position for sequentially driving said fasteners from said holding means and into contact with said anvil means to effect closure of said fasteners; and
,d) alignment means located distally to said rows of fasteners for facilitating and indicating alignment between said holding means and said anvil means, said alignment means comprising at least one pin slidably mounted within a slot in one of said holding means or said anvil means and movable into engagement with an aperture in the other of said holding means or said anvil means in response to movement of said drive means from said proximal position toward said distal position.

Abstract
An apparatus for applying surgical fasteners to body tissue includes an alignment pin assembly having an alignment pin and a corresponding retainer. In a preferred embodiment the alignment pin has a flange with a tissue abutment surface and a circumferential detent. The retainer is preferably a ring shaped member having a tissue abutment surface and which engages with the alignment. The pin and retainer are releasably held in proximity to the distal end of the apparatus within one or the other of the cartridge or anvil member of the apparatus and are simultaneously engaged with each other and applied to body tissue upon firing of the apparatus. Visual inspection of the body tissue after the operation provides an indication as to whether the apparatus was properly aligned during firing.
