The present disclosure provides a circular stapler. The circular stapler includes a stapling head assembly, an anvil detachably attachable to the stapling head assembly, and a handle assembly. The handle assembly includes a handle controller, a connector, and handle transceiver configured to wirelessly transmit a first signal to an external hub. The handle transceiver is separated from the handle controller and is in electrical communication with the handle controller via the connector.

Wireless arrays for surgical staplers

The present disclosure provides a stapling apparatus. The apparatus includes a trocar, a stapling head assembly, and an anvil. The stapling head assembly includes one or more lights positioned on a surface of a tubular casing of the stapling head assembly, the lights extending parallel to a longitudinal axis of the stapling head assembly. The row of lights provide an illumination system to provide indicators of device orientation or location.

Illumination systems for surgical staplers

A powered surgical instrument disclosed. The instrument includes a first circuit portion operable at a first voltage level, a second circuit portion operable at a second voltage level, a voltage source to supply the first voltage level to supply power to electrical components in the first circuit portion; a transistor comprising a control terminal, a first conduction terminal, and a second conduction terminal, and a control circuit coupled to the control terminal of the transistor. The second voltage level is different from the first voltage level. The first conduction terminal is coupled to the voltage source. The control circuit is to set the transistor in a linear mode and control the transistor to set a current for operating the motor.

Motor optimization by minimization of parasitic losses and tuning motor drive configuration

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.
