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.

Abstract: A surgical stapler instrument includes a stapling head assembly that receives a plurality of staples. The staples are configured with features that allow the staples to expand after deployment so that an anastomosis created by the instrument can increase in size after forming. In some versions the staples expand automatically after deployment, and in other versions the staples expand in response to tissue forces imparted upon the staples after deployment. In some versions the staples are configured to be deployed in various patterns that promote expandability of the circular staple line.
