Abstract

A surgical stapling assembly comprising a staple cartridge carrier, an anvil, an outer surface, a closure member, a staple cartridge, and a firing system is disclosed. The anvil is rotatable between a first position and a second position. The closure member is slideable along the outer surface to hold the anvil in the second position. The closure member comprises a clearance opening. The staple cartridge is positioned within the staple cartridge carrier. The staple cartridge comprises staples removably stored therein. The staple cartridge and the anvil define a tissue gap therebetween when the anvil is in the second position. The clearance opening is aligned with the tissue gap when the anvil is in the second position. The firing system is configured to eject the staples from the staple cartridge during a staple firing stroke. The firing system engages the staple cartridge carrier and the anvil during the staple firing stroke.
