A surgical instrument and method of operating same includes an end effector and a shaft assembly. The shaft assembly has proximal and distal shaft portions respectively extending along proximal and distal axes, a first elongate member, and an articulation section. The articulation section extends between the proximal and distal shaft portions and is configured to articulate about a first articulation axis and about a second articulation axis to thereby respectively deflect the end effector along a first plane and a second plane. The articulation section has a first lumen radially offset from the proximal and distal axes that longitudinally intersects the first and second articulation axes. The first lumen movably supports the first elongate member such that the radial spacing of the first elongate member is maintained relative to the proximal and distal axes at each of the first and second articulation axes during deflection of the end effector.
A method includes grasping a user input device in communication with a surgical tool of a robotic surgical system, the surgical tool including an end effector with opposing jaws, squeezing the user input device and thereby actuating a motor that closes the jaws and clamps down on tissue at a surgical site, and calculating with a computer system in communication with the surgical tool work completed by the motor to close the jaws and clamp down on the tissue. The computer system generates one or more effort indicators when the work completed by the motor meets or exceeds one or more predetermined work increments corresponding to operation of the motor, and communicates the one or more effort indicators to an operator.

METHOD FOR CONTROLLING CUTTING MEMBER ACTUATION FOR POWERED SURGICAL STAPLER
A powered surgical stapler includes a motor unit, a movable member, a controller, a sensor assembly, an anvil, and an opposing deck surface. A method of operating the stapler includes controlling the motor unit to actuate the movable member to move from the open position towards the closed position. The method also includes sensing closure data using the sensor assembly. The closure data includes an initial tissue contact position, a gap formed between the anvil and the opposing deck surface, and an axial force on the anvil. The method also includes communicating the closure data to the controller. The method also includes determining at least one of an adjusted closure rate or an adjusted closure stroke using the closure data. The method also includes controlling the motor unit using at least one of the adjusted closure rate or the adjusted closure stroke.

A surgical tool includes a drive housing, a shaft extending from the drive housing, an end effector at an end of the shaft and having opposing jaws and a cutting element, and an articulable wrist configured to rotate the end effector within a plane. The wrist is articulated via antagonistic translation of a pair of drive members. Various systems are provided for homing one or more drive inputs that cause movement in the wrist and/or the end effector, or for controlling articulation of the drive inputs.
An articulable wrist for an end effector includes a first linkage rotatably coupled to a second linkage at a first articulation joint, a flexible member extending at least partially through a central channel cooperatively defined by the first and second linkages, and a first pair of roller supports arranged at the first articulation joint and laterally offset from each other, each roller support extending parallel to a first pivot axis extending through the first articulation joint. A drive cable extends through a first axially-extending conduit defined in the flexible member and through a gap defined between the first pair of roller supports. The drive cable is supported at the first articulation joint by the first pair of roller supports during articulation and the first pair of roller supports prevents a centerline of the drive cable from moving past the first pivot axis during actuation of the end effector.
A surgical tool includes a drive housing, a closure tube that extends from the drive housing, an end effector arranged at an end of the closure tube and having opposing jaws, and a closure yoke mounted to the closure tube and having a projection extending therefrom. A gearing assembly includes one or more spur gears attached to a corresponding one or more drive shafts such that rotation of the one or more drive shafts correspondingly rotates the one or more spur gears, and a closure cam gear positioned to intermesh with the one or more spur gears and defining a profile that receives the projection. Rotating the one or more spur gears causes the closure cam gear to rotate, which causes the projection to traverse the profile, and the projection traversing the profile urges the closure yoke and the closure tube to linearly displace and thereby actuate the jaws.
A surgical instrument includes an end effector, and a shaft assembly. The end effector includes an ultrasonic blade, a rotating body, and a clamp arm movable between an open and a closed position. The shaft assembly extends along an axis and includes clamp arm clocking assembly and a clamp arm pivot assembly. The clamp arm clocking assembly can drive the rotating body and the clamp arm between a first clocked position and a second clocked position. The clamp arm pivot assembly includes an actuator body defining a track, where the actuator body can actuate to drive the clamp arm between the open position and the closed position while the actuator body is in a rotational position relative to the ultrasonic blade. The track houses a portion of the clamp arm in the first clocked position and the second clocked position while the actuator body is in the rotational position.
