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.
Stapling assemblies for use with a surgical stapler are provided. In one exemplary embodiment, the stapling assembly includes a cartridge having a plurality of staples disposed therein and a non-fibrous adjunct formed of at least one fused bioabsorbable polymer and configured to be releasably retained on the cartridge. Adjunct systems for use with a surgical stapler are also provided. Surgical end effectors using the stapling assemblies are also provided. Methods for manufacturing stapling assemblies and using the same are also provided.

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.
