    摘要： 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.

    摘要： A tool assembly for a surgical stapling device includes a channel member for supporting a staple cartridge therein and an anvil to deform a plurality of staples ejected from the staple cartridge thereagainst. The tool assembly also includes a sled which is movable to force the staples from the cartridge against the anvil to staple tissue disposed between the anvil and the staple cartridge. A dynamic clamping member is included which has a pin which movably engages the anvil and a flange which movably engages the channel assembly. The dynamic clamping member is mounted to and movable with the sled. The pin and the flange of the dynamic clamping member cooperating to oppose the forces associated with clamping and stapling tissue and also to maintain a substantially uniform gap between the anvil and the staple cartridge during stapling of the tissue.

    摘要： A surgical device is disclosed which includes a handle portion, a central body portion and a SULU. The SULU includes a proximal body portion, an intermediate pivot member and a tool assembly. The intermediate pivot member is pivotally secured to the proximal body portion about a first pivot axis and the tool assembly is pivotally secured to the intermediate pivot member about a second pivot axis which is orthogonal to the first pivot axis. The SULU includes a plurality of articulation links which are operably connected to the tool assembly by non-rigid links. The articulation links are adapted to releasably engage articulation links positioned in the central body portion. The body portion articulation links are connected to an articulation actuator which is supported for omni-directional movement to effect articulation of the tool assembly about the first and second axes. The handle portion includes a spindle and barrel assembly drive mechanism for advancing and retracting a drive member positioned in the tool assembly. In one embodiment, the tool assembly includes a cartridge assembly having a plurality of staples and an anvil assembly.
