Abstract

A surgical stapling instrument includes an anvil defining a plurality of staple forming pockets and a stapling head assembly configured to drive a plurality of staples against the staple forming pockets of the anvil. The stapling head assembly comprises a coupling member configured to actuate the anvil relative to the stapling head assembly, a firing assembly configured to drive the plurality of staples against the staple forming pockets of the anvil, and a deck member. The deck member includes a deck surface extending radially between an inner circular edge and an outer circular edge, and a plurality of staple openings extending through the deck surface. The plurality of staple openings define at least one cross shape.
