  • Publication number: 20160228145
    Abstract: An end effector includes first and second jaws, first and second buttresses, and an ultrasonic blade. The first jaw includes a fastener cartridge having a first tissue contacting surface and a plurality of fasteners arranged in rows parallel to a longitudinal axis of the first jaw. The first buttress is attached to the first tissue contacting surface and the second buttress is attached to a second tissue contracting surface of the second jaw. The first and second jaws are movable relative to one another and are configured to grasp tissue therebetween. The ultrasonic is activatable to weld the first buttress to the second buttress and to subsequently cut the welded first and second buttresses and tissue grasped between the first and second jaws.

  • Publication number: 20150157323
    Abstract: A surgical stapler is provided. The stapler includes a tubular body portion. A cartridge assembly is disposed at a distal end of the body portion for expelling an annular array of staples. Each of the staples of the annular array of staples has a generally bent backspan. An anvil member disposed at the distal end of the tubular body portion is positioned opposite the cartridge assembly to clinch the staples in tissue upon expulsion of the staples from the cartridge assembly. The anvil member has a corresponding annular array of staple forming buckets. Each of the buckets is configured to accommodate the generally bent configuration of the staples to facilitate formation thereof.

  • Publication number: 20150133740
    Abstract: A gastrectomy device includes an elongated member and a tube. The elongated member has a proximal end and a distal end and defines a longitudinal side window disposed adjacent the distal end. The elongated member defines a first longitudinal channel, a second longitudinal channel, and a plurality of side apertures. The first longitudinal channel is in communication with the longitudinal side window and the plurality of side apertures is in communication with the second longitudinal channel. The tube extends through the first longitudinal channel. An array of lights is associated with the tube to provide illumination. The tube is movable through the elongated member between a first state, in which the tube is disposed within the first longitudinal channel of the elongated member, and a second state, in which a portion of the tube extends through the longitudinal side window of the elongated member.

  • Patent number: 9016545
    Abstract: An end effector includes a first jaw member, a second jaw member, a drive beam, and a drive screw. The second jaw member is pivotally movable relative to the first jaw member between an open position and a closed position. The drive beam is positioned to engage the second jaw member and is longitudinally movable through the first and second jaw members. The drive screw is supported within the first jaw member and includes a threaded portion coupled to the drive beam such that rotation of the drive screw imparts longitudinal movement of the drive beam along the second jaw member to move the first and second jaw members from the open position to the closed position.

  • Publication number: 20150105823
    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.
