  • Patent number: 10959727
    Abstract: A surgical tool assembly. A surgical end effector is movably coupled to a shaft assembly by an articulation joint that is configured to facilitate selective articulation of the surgical end effector relative to the shaft assembly. The shaft assembly includes a proximal end portion and a distal end portion. The distal end portion is operably coupled to the articulation joint. An elongate notch is provided in the distal end portion and is located on one lateral side of a shaft axis that is defined by the shaft assembly. The shaft assembly may be configured to prevent the distal end portion from buckling when an axial actuation motion is applied to the proximal end.

    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.

  • Patent number: 10245029
    Abstract: A surgical instrument comprising an elongate shaft assembly that defines a shaft axis. The surgical instrument includes a surgical end effector that has a distal end and a proximal end. The proximal end is pivotally coupled to the elongate shaft assembly for selective pivotal travel about an articulation axis that extends transversely relative to the shaft axis. The surgical end effector is selectively pivotable about the articulation axis from an unarticulated position wherein the distal end of the surgical end effector is located an unarticulated distance from the articulation axis to articulated positions wherein the distal end of the surgical end effector is located a corresponding articulated distance from the articulation axis that is less than the unarticulated distance.

  • Patent number: 10245030
    Abstract: A surgical instrument comprising an elongate shaft assembly that defines a shaft axis. A surgical end effector is pivotally coupled to the elongate shaft assembly for selective articulation relative to the elongate shaft assembly about an articulation axis that is transverse to the shaft axis. An articulation cable is coupled to the surgical end effector at a point of attachment and is journaled on a proximal pulley that is supported on the elongate shaft assembly. The proximal pulley defines a proximal pulley axis that is located a tension distance from the point of attachment. An articulation driver is coupled to the articulation cable for selectively causing the articulation cable to rotate about the proximal pulley in first and second articulation directions. An adjustable tensioning assembly interfaces with the proximal pulley to selectively adjust the tensioning distance.
