1. A surgical system, comprising:

  • a surgical instrument, comprising;

    an ultrasonic transducer;

    a blade extending distally from the ultrasonic transducer along a longitudinal axis;

    a motor coupled to the ultrasonic transducer to rotate the ultrasonic transducer and the blade about the longitudinal axis; and

    a sheath extending distally along the longitudinal axis, wherein the blade is rotatable by the motor about the longitudinal axis between an unexposed orientation within the sheath and an exposed orientation;

    a power supply; and

    a control module, wherein the control module is configured to;

    receive an indication to operate the surgical instrument according to an ultrasonic-only mode;

    instruct the motor to rotate the blade to a park position corresponding to the exposed orientation; and

    activate the ultrasonic transducer to longitudinally vibrate the blade at the park position.
