    Abstract: 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.

    Abstract: An end effector includes a cartridge assembly having a first tissue contact surface, an anvil assembly having a second tissue contact surface, and one or more tissue pockets defined in one of the first or second tissue contact surfaces. The anvil and the cartridge assemblies are moveable between an open position and a closed position to selectively clamp tissue between the first and second tissue contact surfaces. Each tissue pocket is configured to capture tissue therein while the anvil and the cartridge assemblies are disposed in the closed position. Each tissue pocket is configured to prevent the tissue from migrating away from the first and second tissue contact surfaces while the tissue is clamped between the first and second tissue contact surfaces.

    Abstract: A joint assembly of an adapter defines a first longitudinal axis and includes first and second hinges, first and second rings, a joint cover, and a biasing mechanism. The joint cover has first and second cover portions. The first ring is pivotally coupled to the first hinge and the first cover portion is pivotally coupled to the first hinge to define a first joint center. The second ring is pivotally coupled to the second cover portion and the second hinge is pivotally coupled to the second ring to define a second joint center that is spaced from the first joint center. The first and second joint centers define a cover axis of the joint cover. The biasing mechanism is engaged with the first ring and the joint cover to bias the joint cover towards an aligned configuration in which the cover axis is aligned with the first longitudinal axis.

    Abstract: A surgical device comprising a first jaw member, a second jaw member, a clamping member and a clamp apparatus is disclosed. The clamping member is slidably positioned to translate at least partially through the first jaw member. The clamping member engages the first jaw member and the second jaw member, and has a knife blade for cutting tissue. A flange of the clamping member is configured to engage a cam surface to pivot the second jaw member with respect to the first jaw member from an open position toward an approximated position. The clamp apparatus is movable from a retracted position to an advanced position for preventing a gap between proximal portions of the first jaw member and the second jaw member from exceeding a predetermined distance. The clamping member and the clamp apparatus are separately movable.

    Abstract: A hand-held electromechanical surgical device is configured to selectively connect with a surgical accessory. The surgical device includes a power-pack, an outer shell housing, and a gasket. The power-pack is configured to selectively control a surgical accessory. The outer shell housing includes a distal half-section and a proximal half-section, the distal half-section and the proximal half-section together defining a cavity configured to selectively encase substantially the entire power-pack therein. The gasket is located between the distal half-section and the proximal half-section of the outer shell housing. The gasket is configured to create a seal between the distal half-section and the proximal half-section and to provide a sterile barrier between the power-pack and an outside environment outside the outer shell housing.
