摘要： An instrument assembly can comprise a shaft comprising a first drive portion of a drive system, an end effector comprising a second drive portion of the drive system, and an articulation joint rotatably connecting the end effector to the shaft. The end effector is rotatable between a first position and a second position about the articulation joint, wherein the first drive portion is not operably engaged with the second drive portion when the end effector is in the first position, and operably engaged with the second drive portion when the end effector is in the second position. The end effector can comprise a first jaw and a second jaw, wherein the first jaw is movable relative to the second jaw between an open position and a closed position within a closure plane, and wherein the end effector is rotatable within an articulation plane which is co-planar with the closure plane.

摘要： A surgical clip applier and methods for applying surgical clips to a vessel, duct, shunt, etc., during a surgical procedure are provided. In one exemplary embodiment, a surgical clip applier is provided having a housing with a trigger movably coupled thereto and a shaft extending therefrom with opposed jaws formed on a distal end thereof. The trigger is adapted to advance a clip to position the clip between the jaws, and to move the jaws from an open position to a closed position to crimp the clip positioned therebetween. The surgical clip applier can include a variety of features to facilitate use of the device, including features to prevent misalignment of the jaws and clip therebetween, features to protect the jaws, and features to ensure proper closure of the jaws and clip therebetween.

摘要： A surgical instrument, operable to compress, staple, and cut tissue, includes a body, a shaft, and an end effector with a pair of jaws. A placement tip that is bent, angled, or curved and extends distally from one of the jaws of the end effector. The placement tip is elastically deformable when the placement tip is subject to a clamping force, such as when the end effector is closed with the jaws in contact or when tissue is clamped between the jaws of the end effector. When the placement tip deflects, relative angles defined in part by the placement tip vary compared to an initial state without the clamping force. Furthermore, a distal end of the placement tip may change position based on the state of deflection of the placement tip in response to the clamping force.

摘要： A surgical instrument includes a body assembly, a shaft assembly extending distally from the body assembly along a shaft axis, and an end effector at a distal end of the shaft assembly. The shaft assembly includes an outer tube configured to rotate relative to the body assembly about the shaft axis. The surgical instrument further includes a slip ring assembly configured to enable electrical communication between the shaft assembly and the body assembly while permitting relative rotation therebetween. The slip ring assembly includes a first electrical contact supported by the outer tube, and a second electrical contact electrically coupled with the first electrical contact and positioned radially outward of the outer tube. The first electrical contact is configured to rotate with the outer tube about the shaft axis relative to the second electrical contact while the first and second electrical contacts remain electrically coupled.

摘要： A surgical stapling assembly is disclosed. The assembly can include a cartridge body having cavities defined therein forming a pattern of openings in the deck of the cartridge body. The pattern can include longitudinally-repeating clusters of cavity ends. The assembly can also include fasteners removably positioned in the cavities. The pattern of openings can comprise openings on a first side of the cartridge body comprising inner openings each defining an inner proximal-to-distal axis oriented parallel to the longitudinal axis, outer openings each defining an outer proximal-to-distal axis obliquely-oriented relative to the longitudinal axis at an outer angle, and intermediate openings each defining an intermediate proximal-to-distal axis obliquely-oriented relative to the longitudinal axis at an intermediate angle, wherein the intermediate angle is different than the outer angle. The assembly can include a sled having offset ramps and/or an anvil comprising an arrangement of forming pockets proximal to the tissue stop.
