摘要

An apparatus includes an end effector including an anvil and lower jaw. The anvil is pivotable toward the lower jaw to capture tissue. The apparatus further includes a stapling and severing assembly configured to sever and staple tissue clamped between the anvil and the lower jaw. A staple cartridge is coupled with the lower jaw. The staple cartridge includes a deck facing the anvil, a plurality of staples positioned in a plurality of staple openings formed through the deck, and a cinching feature positioned on the deck. At least a portion of the cinching feature is configured to be captured by the staples as the staples are driven out of the staple openings in response to activation of the stapling and severing mechanism.
