Abstract
A surgical instrument includes a first and second jaw actuatable between an open and closed position, a buttress assembly having a compressible material, and a fastener assembly associated with the second jaw. The fastener assembly and the buttress assembly may cooperatively grasp tissue while the first and second jaws are in the closed position. The fastener assembly includes a deck defining a plurality of openings and a plurality of fasteners each housed within a respective opening of the plurality of openings. Each fastener can actuate out of the respective opening and into the buttress assembly. Each fastener includes a first leg having a piercing tip, and an attachment feature associated with the first leg. The attachment feature can engage the buttress assembly to couple the first leg with the buttress assembly without bending a portion of the first leg associated with the piercing tip.
