Abstract
A surgical system includes a surgical instrument having a body, an ultrasonic transducer, a shaft extending distally from the body, and an end effector at a distal end of the shaft and being operable to treat tissue with ultrasonic energy. An accessory device is configured to operatively couple the surgical instrument with a generator operable to power the surgical instrument to provide ultrasonic energy. A primary EEPROM is provided within the instrument body and is operable to track usage of the surgical instrument. The system further includes at least one of: an accessory EEPROM integrated into the accessory device and being operable to track usage of the accessory device; a transducer EEPROM integrated into the ultrasonic transducer and being operable to track usage of the ultrasonic transducer; or an ASIC integrated into the accessory device and being operable to communicate with the generator regarding a state of the surgical instrument.
