Abstract
A surgical stapling device includes an anvil assembly having a center rod and an anvil head that is pivotally coupled to the center rod. The anvil head supports a cut ring assembly that is movable between a pre-fired or retracted position in which the cut ring is positioned to retain the anvil head in an operative position and an advanced position in which the cut ring assembly is positioned to allow movement of the anvil head to a tilted position. The anvil assembly also includes at least one support member that is movable from a pre-fired position extending into the anvil head to an advanced position extending from the distal end of the anvil head to allow the cut ring assembly to move from the first position to the second position. The at least one support member can be returned to the pre-fired position after the stapling device is fired and the anvil head has tilted to reset the anvil head to the operative position.
