Abstract

An applicator instrument for dispensing surgical fasteners includes a housing, a firing system disposed in the housing, an actuator coupled with the housing for activating the firing system, an elongated shaft extending from the housing, the elongated shaft having a proximal end secured to the housing, a distal end, and a first axis extending between the proximal and distal ends, one or more surgical fasteners disposed in the elongated shaft, and a distal end cap secured to the distal end of the elongated shaft. The distal end cap has a surgical fastener dispensing window for dispensing the one or more surgical fasteners from the distal end cap. The firing system includes a firing rod that extends through the elongated shaft for dispensing the one or more surgical fasteners from the distal end cap. The firing rod has a proximal section that moves along the first axis of the elongated shaft and a distal section that moves along a second axis that defines an angle with the first axis.
