A surgical instrument is disclosed. The surgical instrument includes a drive system and a control circuit. The drive system includes an electric motor. The control circuit includes an acoustic sensor, and is configured to utilize a parameter of the drive system measured by the acoustic sensor to control a speed of the electric motor.

A surgical instrument is disclosed comprising a plurality of drive systems and one or more shifting systems. The functionality of the surgical instrument is controlled by the shifting systems.

A surgical instrument is disclosed. The surgical instrument includes an electric motor and a control circuit. The control circuit includes a plurality of logic gates and a monostable multivibrator. The monostable multivibrator is connected to a first one of the logic gates. The control circuit is configured to alter a rate of action of a function of the surgical instrument by controlling a speed of rotation of the electric motor based on a sensed parameter.

A surgical instrument is disclosed. The surgical instrument includes a body, a shaft and a control circuit. The control circuit includes at least one sensing device and is to determine a presence of another surgical instrument proximate to the surgical instrument within an environment of a surgical procedure.

A surgical instrument is disclosed comprising a housing and a control circuit mounted to and/or embedded in the housing.

A surgical instrument is disclosed comprising an actuator and circuitry mounted on and/or embedded in the actuator.

A surgical instrument is disclosed comprising a control system and a strain gage circuit. The operation of the control system is modifiable by an input from the strain gage circuit.

A surgical hub is disclosed. The surgical hub includes a processor and a memory coupled to the processor. The memory stores instructions executable by the processor to receive image data from an image sensor, generate a first image based on the image data, display the first image on a surgical hub display coupled to the processor, receive a signal from a non-contact sensor, the signal indicative of a position of a surgical device, generate a second image based on the signal indicative of the position of the surgical device, and display the second image on the surgical hub display coupled to the processor.

A method for controlling a surgical instrument is disclosed. In at least one instance, the surgical instrument comprises a shroud and the operation of the surgical instrument is modified based on input from a sensing circuit configured to sense a parameter of the shroud. In certain instances, the surgical instrument comprises a strain gage circuit and the operation of the surgical instrument is modified based on input from the strain gage circuit.

A surgical instrument is disclosed. The surgical instrument includes a shaft, a sensing array and a fluid detection circuit. The sensing array is positioned within the shaft. The fluid detection circuit is electrically coupled to the sensing array, and is configured to determine when a fluid originating from an environment external to the shaft is present within the shaft.
