1. A surgical instrument, comprising:
a housing;
an ultrasonic transducer contained in the housing, including a first ultrasonic transducer optimized for cutting and a second ultrasonic transducer, separate from the first ultrasonic transducer and optimized for sensing;
a collet assembly arranged on a distal end of the housing;
a dissection head having an attachment portion configured to be selectively driven by the ultrasonic transducer, the dissection head configured to be received by the collet assembly; and
a controller operable to initiate and stop the ultrasonic transducer according to an alternating duty cycle such that the second ultrasonic transducer is on when the first ultrasonic transducer is off,
wherein the ultrasonic transducer is configured to operate the first ultrasonic transducer at a cutting frequency or the second ultrasonic transducer at a sensing frequency according to the alternating duty cycle.
