Abstract:
1. A surgical stapling device for joining tissue portions, comprising: a handle assembly; an elongate body extending from the handle assembly; a cartridge assembly supported on a distal end of the elongate body, the cartridge assembly including a staple cartridge containing a plurality of surgical staples in an annular array; an anvil assembly at a distal end of the surgical stapling device, the anvil assembly having a shaft for removably coupling the anvil assembly to the cartridge assembly and a head pivotally mounted to a distal end of the shaft, the anvil assembly translatable relative to the cartridge assembly between a first position, where the anvil assembly is spaced from the cartridge assembly, and a second position, where the anvil assembly is approximated relative to the cartridge assembly for clamping tissue therebetween, the head of the anvil assembly transitionable between a first condition, where a tissue contacting surface of the head is substantially perpendicular to the shaft, and a second condition, where the tissue contacting surface of the head is tilted relative to the shaft; and a sleeve member slidably disposed about the shaft of the anvil assembly, the sleeve member transitionable between a first position, where the sleeve member engages the head of the anvil assembly to secure the head in the first condition, and a second position, where the sleeve member is disengaged from the head of the anvil assembly to allow the head to transition to the second condition.
