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; characterized in that the cartridge assembly includes a locking member, the locking member translatable relative to the sleeve member to engage a protrusion of the sleeve member when the anvil assembly is in the second position, the locking member configured to axially maintain the sleeve member relative to the cartridge assembly and to disengage the sleeve member from the head of the anvil assembly when the anvil assembly transitions from the second position to the first position. 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; characterized in that the cartridge assembly includes a locking member, the locking member translatable relative to the sleeve member to engage a protrusion of the sleeve member when the anvil assembly is in the second position, the locking member configured to axially maintain the sleeve member relative to the cartridge assembly and to disengage the sleeve member from the head of the anvil assembly when the anvil assembly transitions from the second position to the first position.
