    Abstract: 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 unclamp lockout mechanism. The unclamp lockout mechanism including a pawl rotatably mounted to the shaft and positioned proximal to a closure yoke operatively coupled to the shaft, the pawl being pivotable between a stowed position, where the pawl is received within an aperture of the shaft, and a deployed position, where the pawl protrudes out of the aperture, and a biasing device that biases the pawl toward the stowed position. When the pawl is in the stowed position, the closure yoke is movable to a proximal position over at least a portion of the pawl to open the opposing jaws. When the pawl is in the deployed position, the closure yoke is prevented from moving to the proximal position.

    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.

    Abstract: Systems and methods for articulation calibration of a surgical tool configured to be coupled to a robotic surgical system are provided. The tool including a tool shaft with an end effector has at least one linkage member extending along the shaft and operably coupled to the end effector such that force selectively applied to the linkage member is able to cause articulation of the end effector. The tool can also include a homing mechanism. To perform articulation calibration of the end effector, it can be constrained, force can be applied to the linkage member to attempt articulation of the end effector until a resistance against further articulation exceeds a threshold, and a home position of the end effector can be determined based on a force at which the resistance has exceeded the threshold.

    Abstract: Robotic surgical systems are provided for control of an end effector in response to actuation of a user interface device based upon different control states. In each control state, selected movement directions of the user interface device are either coupled to or decoupled from corresponding movements directions of the end effector. Decoupled movement directions can be recoupled by positioning the user interface device within a range of where the user interface device and the end effector were decoupled. To assist with such recoupling, a graphical image estimating a position of the end effector that would be achieved, based upon a current position of the user interface device, if the decoupled movement direction was recoupled can be overlaid upon a current position of the end effector.

    Abstract: Various systems and methods of selecting a display language for a surgical instrument are disclosed. The surgical instrument includes a handle assembly and a module, such as a shaft assembly, that is interchangeably connectable to the handle assembly. The handle assembly includes a first memory configured to store a language parameter and a control circuit that is operably coupled to the memory. The module includes a second memory configured to store a textual phrase in a plurality of languages. When the module and the handle assembly are connected together, the control circuit is configured to retrieve, from the second memory, the textual phrase in a language corresponding to the language parameter.

    Abstract: A powered surgical instrument is disclosed comprising a housing, an elongate shaft extending from the housing, and an end effector extending from the elongate shaft. The end effector is configured to perform at least one end effector function. The powered surgical instrument further comprises a motor and a segmented circuit. The segmented circuit comprises a plurality of circuit segments configured to control the powered surgical instrument. The powered surgical instrument further comprises a power source configured to supply each one of the plurality of circuit segments with a different voltage. The powered surgical instrument further comprises a boost converter configured to provide an increased voltage to one of the plurality of circuit segments when current draw in another of the plurality of circuit segments exceeds a predetermined value.
