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.

Abstract
In one general aspect, various embodiments are directed to systems and methods for controlling a surgical instrument. The surgical instrument may comprise an ultrasonic transducer, a blade extending distally from the ultrasonic transducer along a longitudinal axis, and a motor coupled to the ultrasonic transducer. The motor, when activated, may rotate the ultrasonic transducer and the blade about the longitudinal axis. A control system may receive an indication to operate the surgical instrument according to an ultrasonic-only mode. The control system may instruct the motor to rotate the blade to a park position, and activate the ultrasonic transducer to longitudinally vibrate the blade.
