1. A surgical instrument, comprising:
a housing;
an ultrasonic transducer contained in the housing and capable of acting as an ultrasonic receiver, wherein the ultrasonic transducer is a first ultrasonic transducer optimized for cutting and the surgical instrument further comprises a second ultrasonic transducer, separate from the first ultrasonic transducer optimized for sensing;
an output member at least partially received in the housing and configured to be driven by the ultrasonic transducer;
a dissection head having an attachment portion configured to be selectively driven by the ultrasonic transducer; and
a controller operable to initiate and stop the first ultrasonic transducer and the second ultrasonic transducer according to an alternating duty cycle.
