  • Patent number: 10517595
    Abstract: A surgical end effector including a first jaw that is configured to operably support a surgical staple cartridge therein and a second jaw that is movably supported relative to the first jaw between open and closed positions. A firing member is supported for axial movement within the first jaw along a shaft axis between a starting position and an ending position. A firing member lockout system is movable between an unlocked position wherein the firing member lockout system is out of engagement with the firing member and a locked position wherein the firing member lockout system is configured to prevent the firing member from being distally advanced from the starting position unless an unfired staple cartridge comprising a cam assembly that is located in an unfired position is supported within the first jaw. The firing member lockout system is configured to be moved from the unlocked position to the locked position when the second jaw is moved to the closed position.

  • Publication number: 20190328416
    Abstract: Various exemplary systems, devices, and methods are provided for resisting torque in articulating surgical tools. In general, a surgical tool can include an elongate shaft having at a distal end thereof an end effector configured to engage tissue. The end effector can be configured to articulate relative to the elongate shaft. The surgical tool can include a cutting element configured to translate longitudinally along the end effector to cut the engaged tissue. When the end effector is articulated, the longitudinal translation of the cutting element along the end effector exerts a torque force on the end effector that urges the end effector away from its current angled orientation. The surgical tool can be configured to have a corrective tension or force applied thereto that counteracts the torque force.
