Abstract
A surgical stapling device includes an end effector configured to accommodate prolapsed tissue to perform an anastomosis externally of a body cavity. The surgical stapling device has an anvil assembly and a shell assembly. The anvil assembly includes an anvil plate and anvil rods that extend proximally from the anvil shaft and are positioned about the shell assembly. The anvil plate has a proximally facing surface that defines staple forming pockets. The shell assembly includes a shell housing that defines a cavity, an annular pusher that is movable within the cavity from a retracted position to an advanced position, an annular staple cartridge, and an annular knife blade. The staple cartridge includes staple receiving pockets that receive staples, and the knife blade is secured to the pusher radially outwardly of the staple receiving pockets.
