    Abstract: A control circuit for use with a robotic surgical system. The control circuit is configured to receive a parameter indicative of a rotary position of an articulation motor. The articulation motor is configured to drive an articulation joint of a robotic surgical tool, wherein the articulation motor is configured to move through a first range of positions and a second range of positions. The control circuit is further configured to implement a first operating state, and implement a second operating state when the parameter corresponds to a transition of the articulation motor from the first range of positions to the second range of positions. The control circuit is further configured to re-implement the first operating state when the parameter corresponds to a return of the articulation motor from the second range of positions into the first range of positions by a threshold anti-dither angle.

    Abstract: Surgical instruments and control systems therefor are disclosed. A surgical instrument can comprise: a power circuit comprising a power source and a switch, a microcontroller coupled to the power circuit, a handle comprising an attachment portion, and a control circuit in signal communication with the microcontroller. The attachment portion can comprise a first electrical contact in signal communication with the microcontroller. The control circuit can comprise a sensor configured to detect an attachment state of the attachment portion. The control circuit can communicate the detected attachment state to the microcontroller, and the microcontroller can ignore signals from the first electrical contact when the control circuit communicates a detached state. The attachment portion can comprise a second electrical contact coupled to a second power circuit, and the second power circuit can decouple the second electrical contact and the second power source when the sensor detects the detached state.

    Abstract: A surgical stapler. The surgical stapler includes a drive system, an electric motor, a battery and a control system. The electric motor is mechanically coupled to the drive system. The battery is electrically couplable to the electric motor. The control system is electrically connected to the electric motor and includes an H-bridge circuit, an electrically resistive element and an electrically inductive element. The H-bridge circuit includes a high side and a low side. The low side of the H-bridge circuit includes first and second switching devices. The electrically resistive element is electrically connected in series with the first switching device. The electrically inductive element is electrically connected to the electrically resistive element. The control system is configured to control a force applied to the drive system based on a current downstream of the electrically resistive element.

    Abstract: A surgical instrument can comprise a handle, a shaft extending from the handle, and an end effector rotatably coupled to the shaft by an articulation joint. The surgical instrument can further include a staple cartridge positioned within the end effector and a firing drive operably coupled with a trigger wherein the operation of the trigger can advance and/or retract a firing member of the firing drive relative to the end effector. The surgical instrument can further comprise an articulation drive which is selectively engageable with the firing drive. When the articulation drive is engaged with the firing drive, the operation of the firing drive can operate the articulation drive and articulate the end effector. When the articulation drive is not engaged with the firing drive, the firing drive can be operated independently of the articulation drive.

    Abstract: A robotic surgical tool includes a tool driver, a drive housing mountable to the tool driver and including one or more component parts made of or including a magnetically responsive material, a first inductor coil included on the tool driver and configured to generate a magnetic field, and a second inductor coil included on the drive housing and configured to measure an intensity of the magnetic field and a field distortion caused by the one or more component parts. A change in the field distortion provides an indication of movement of the one or more component parts.

    Abstract: A surgical instrument comprises an end effector, a shaft, and a housing extending proximally from the shaft. The surgical instrument includes an articulation assembly configured to articulate the end effector relative to the shaft, a firing assembly configured to fire a plurality of staples, for example, and a locking member movable between a locked configuration and an unlocked configuration. The housing is removably couplable to the shaft when the locking member is in the unlocked configuration and the housing includes a motor configured to drive at least one of the firing assembly and the articulation assembly. The housing also includes a controller in communication with the motor, wherein the controller is configured to activate the motor to reset at least one of the firing assembly and the articulation assembly to a home state when the locking member is moved between the locked configuration and the unlocked configuration.
