    摘要： A staple driver actuator for a surgical stapler includes a base having at least one bottom surface. The bottom surface defines a plane and is configured to slide longitudinally relative to a stapling assembly of the surgical stapler. The staple driver actuator also includes at least one rail extending upwardly from the base. The at least one rail includes at least one rail cam surface, and the rail cam surface is inclined relative to the plane. The staple driver actuator further includes a first surface texture on a first portion of the staple driver actuator, and a second surface texture on a second portion of the staple driver actuator. The second surface texture is smoother than the first surface texture.

    摘要： A surgical instrument system that includes a housing and a rotatable drive shaft, a motor operably coupled to the drive shaft, and a plurality of replaceable end effectors that can be connected to the housing. Each replaceable end effector includes a drive screw that is turned a fixed number of revolutions by the motor-driven rotatable drive shaft when the end effector is connected to the housing. Each end effector further comprises a firing member operably coupled with the drive screw of the end effector. The drive screw is configured to displace the firing member over a firing length as a result of the fixed number of revolutions. In certain embodiments, each replaceable end effector can include a drive screw with a thread pitch set to the firing length divided by the fixed number of revolutions.

    摘要： A surgical instrument comprising a handle, an elongate shaft, an end effector, an articulation joint, an articulation knob, an articulation member, and an articulation lock is disclosed. The end effector is rotatably coupled to the elongate shaft by the articulation joint. The articulation knob is rotatable between an un-rotated position and rotated positions. The articulation lock comprises a lock member configured to move between a locked position where the lock member is engaged with a detent of the end effector and an unlocked position where the lock member is disengaged from the end effector. The lock member is movable between the locked position and the unlocked position by the articulation knob. The articulation member is moved from a proximal position toward a distal position to articulate the end effector when the articulation knob is moved from the un-rotated position toward a rotated position.
