ABSTRACT:
The present invention provides a system for implementing surgical procedures which includes an ultrasonic surgical hand piece having an end-effector, a console having a digital signal processor (DSP) for controlling the hand piece, an electrical connection connecting the hand piece and the console, and a memory, such as an EEPROM (Electrically Erasable Programmable Read Only Memory), disposed in the electrical connection. The console sends a drive current to drive the hand piece which imparts ultrasonic longitudinal movement to the blade. The console reads the memory and authenticates the hand piece for use with the console if particular or proprietary data are present in the memory. Moreover, to prevent errors in operating the hand piece, the memory can store certain diagnostic information which the console can utilize in determining whether the operation of the hand piece should be handicapped or disabled. Furthermore, the memory can be used to reprogram the console, if needed.
