Abstract

An applicator instrument for dispensing surgical fasteners includes a housing, an elongated shaft, and an elongated conduit extending through the elongated shaft. A firing system is disposed within the housing. The firing system has an insertion tool having a top surface that extends proximal and distal ends thereof and a stripper ramp that projects above the top surface. An actuator activates the firing system to commence a firing cycle. During the firing cycle, the firing system drives the insertion tool toward the distal end of the elongated shaft. The elongated conduit has a top wall with a top notch formed therein. The stripper ramp slides through the top notch for guiding movement of the insertion tool as the firing system drives the insertion tool toward the distal end of the elongated shaft.
