    Abstract: A surgical tool that comprises a surgical end effector comprising opposing jaws, an elongate shaft extending distally to the surgical end effector, and a housing defining a passage therethrough, wherein the elongate shaft extends through the passage. The surgical tool further comprises an actuation mechanism configured to selectively move the housing along the elongate shaft relative to the surgical end effector. The actuation mechanism comprises a pulley, a cable engaged with the pulley, and a lock arrangement configured to releasably lock the housing relative to the elongate shaft. The lock arrangement comprises a washer positioned around the elongate shaft. The cable is engaged with the washer. An actuation of the pulley is configured to apply a tension to the cable to pivot the washer relative to the elongate shaft from a locked orientation to an unlocked orientation.

    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.

    Abstract: Various embodiments of tool assemblies are provided having at least one rotary input coupling and at least one linear input coupling for allowing either a rotary output or a linear output (e.g., from a tool driver on a surgical robot) to activate at least one mechanism of the tool assembly. For example, mechanisms of the tool assembly can include a clamping assembly, a firing assembly, an articulation assembly, and a roll assembly. The clamping assembly can open and close jaws of an end effector, the firing assembly can translate a knife assembly through the end effector to fire staples and cut tissue, the articulation assembly can articulate the end effector, and the roll assembly can rotate the elongate shaft and/or the end effector.
