Abstract
A circular stapling device includes a handle assembly, an elongate body portion that extends distally from the handle assembly, a shell assembly supported on a distal end of the elongate body portion, an anvil retainer assembly extending through the shell assembly, and an anvil assembly supported on the anvil retainer assembly. The anvil retainer assembly includes a retainer member including a retainer body and an engagement member that is pivotally supported on the retainer body. The engagement member is movable axially in relation to the retainer body from a retracted position to an advanced position to move the engagement member to from a locked position to an unlocked position in relation to the retainer body. In the unlocked position, the engagement member is movable from a non-articulated position to an articulated position in relation to the retainer body.
