  • Patent number: 11331097
    Abstract: A surgical stapling apparatus includes an actuating device including an elongated shaft. A tool assembly is disposed on a distal end of the shaft. The tool assembly includes a first jaw member supporting a cartridge assembly having a plurality of surgical fasteners, and a second jaw member supporting an anvil. The first jaw member is movable in relation to the second jaw member between a spaced position and an approximated position. One of the first or second jaw members includes a cantilever at a proximal end thereof. A firing cam bar assembly is slidably disposed within the tool assembly and includes a cam surface configured to engage the cantilever to move the first and second jaw member towards the approximated position and a distal end configured to deploy the plurality of surgical fasteners from the cartridge assembly.

  • Publication number: 20200138432
    Abstract: A surgical stapling apparatus includes a handle assembly, a shaft assembly extending distally from the handle assembly, and an end effector selectively detachable from the shaft assembly. The end effector includes a first jaw member and a second jaw member. The first jaw member supports a lever that is pivotally movable relative to the first jaw member between an extended position and a retracted position. The lever is in contact with a leaf spring to spring bias the lever to the extended position. The second jaw member supports a drive beam that is selectively engagable with the lever to facilitate a pivotal movement of the second jaw member relative to the first jaw member between an unapproximated state and an approximated state.

  • Publication number: 20200121320
    Abstract: A surgical stapler has a tool assembly including an anvil and a staple cartridge having a series of staples which are supported and configured to be rotatably ejected from the staple cartridge into the anvil to suture tissue. In embodiments, the surgical stapler includes a cartridge that supports a plurality of rotatable pushers. Each pusher supports a curved, substantially U-shaped staple having a single tissue penetrating distal leg portion and a proximal leg portion. The pusher is rotatable to drive the distal leg portion into an anvil to deform the staple into a substantially D-shaped configuration.

  • Publication number: 20200015822
    Abstract: A surgical stapler includes a body portion and a tool assembly. The body portion includes a large diameter portion and a small diameter portion extending distally from the large diameter portion. The large diameter portion supports larger internal components of the device including a lockout assembly adapted to prevent refiring of the stapler to allow the diameter of the small diameter portion of the device to be minimized to facilitate passage of the small diameter portion of the stapler and the tool assembly through an 8 mm trocar.
