Abstract

An ultrasonic instrument includes a housing, an ultrasonic transducer support by the housing, and an integrated usage indicator. The housing is configured to removably connect to a shaft assembly. The ultrasonic transducer is configured to be acoustically connected to a waveguide and operated a predetermined number of use cycles. The integrated usage indicator is operatively connected to the housing and includes a used state indicator. The used state indicator is configured to indicate to a clinician in a used state when the ultrasonic transducer has been operated at least the predetermined number of use cycles for limiting usage of the ultrasonic transducer to the predetermined number of use cycles.
