Abstract
A surgical device comprising an anvil, a cartridge assembly, a dynamic clamping member, a clamp ring and a drive mechanism is disclosed. The cartridge assembly is configured to house a plurality of fasteners at least partially therein. The anvil and cartridge assembly are movable in relation to each other between open and approximated positions. The dynamic clamping member is slidably positioned to translate at least partially through the cartridge assembly to eject fasteners therefrom. The dynamic clamping member engages the anvil and the cartridge assembly. The clamp ring is movable from a retracted position to an advanced position at least partially encircling proximal portions of the anvil and cartridge assembly for preventing a gap between proximal portions of the anvil and cartridge assembly from exceeding a predetermined distance. The drive mechanism includes a single actuator for driving both the clamp ring and the dynamic clamping member.
