20. A method of reusing an ultrasonic transducer of a surgical instrument, the method comprising:
(a) connecting a shaft assembly to a housing;
(b) recording the connection of the shaft assembly to the housing on a memory;
(c) preventing electrical powering of the ultrasonic transducer while a first use indicator remains selectively unmoved relative to the housing; and
(d) selectively moving the first use indicator relative to the housing to a first used state thereby enabling electrical powering of the ultrasonic transducer for reuse of the ultrasonic transducer.
