Abstract: A surgical instrument system comprising a motor system and a control circuit is disclosed. The motor system comprises a motor and a drive train coupleable to the motor and configured to actuate a firing member through a staple firing stroke. The control circuit is coupled to the motor, wherein the control circuit comprises a motor controller configured to control the motor, and wherein, during the staple firing stroke, the control circuit is configured to actuate the firing member through the staple firing stroke, monitor a parameter of the motor system during the staple firing stroke, identify when the firing member is within an active adjustment portion of the staple firing stroke; and automatically adjust, at a frequency, tuning parameters of the motor controller with based on the monitored parameter of the motor system during the active adjustment portion of the staple firing stroke.

Abstract: Methods, devices, and systems for controlling a tissue-treatment motion by a surgical instrument are disclosed.

Abstract: A surgical stapling system includes a motor, a gear reducer assembly, a drive train, and a motor controller. A method of controlling the motor includes applying a first signal to the motor, receiving drive train operational data, comparing the drive train data to baseline data, and applying a signal having a different shape than the first signal to the motor. A method of characterizing the motor includes transmitting a perturbation signal, receiving motor function parameters, determining stapler system characteristics, and adjusting a controller function. A method of controlling a stepper motor includes applying a signal to the stepper motor, receiving stepper motor operational data, comparing the data to baseline data, and adjusting the signal. Another method of controlling the motor includes receiving motor rotational data, receiving gear rotation data, calculating a mechanical transfer function, determining non-idealities of the stapling system, and modifying a control signal based on the non-idealities.

Abstract: Embodiments of the presently described device, system and method support upper extremity therapy through a control device. In various embodiments, the control device is provided as a central hub with atomic elements extending outwardly thereof, and the control device can incorporate a movement interpretation circuit, a touch detection circuit and/or one or more sensory transducers.
