Sliding sleeve for circular stapling instrument reloads
First Claim
1. An anvil assembly configured to attach to a surgical stapling device, comprising:
- a shaft defining a longitudinal axis;
a head pivotally mounted to a distal end of the shaft, the head transitionable between a first condition, where a tissue contacting surface of the head is substantially perpendicular to the longitudinal axis, and a second condition, where the tissue contacting surface of the head is tilted relative to the longitudinal axis; and
a sleeve member slidably disposed about the shaft, the sleeve member including a proximal end including a nub for engagement with a locking sleeve of a cartridge assembly of a surgical stapling device, the sleeve member being transitionable between a first position, where the sleeve member engages the head to secure the head in the first condition, and a second position, where the sleeve member is disengaged from the head to allow the head to transition to the second condition.

Abstract
A surgical stapling device and method for joining tissue portions are provided including a handle assembly, an elongate body extending from the handle assembly, a cartridge assembly supported on a distal end of the elongate body, and an anvil assembly at a distal end of the surgical stapling device. The anvil assembly includes a shaft for removably coupling the anvil assembly to the cartridge assembly and a head pivotally mounted to a distal end of the shaft. A sleeve member is slidably disposed about the shaft of the anvil assembly and is transitionable between a first position, where the sleeve member engages the head of the anvil assembly to secure the head in an un-tilted condition, and a second position, where the sleeve member is disengaged from the head of the anvil assembly to allow the head to tilt.
