This is an ultrasonic surgical device consisting of a generator, a foot switch, and a handpiece. 

Generator is activated when an electric current flow through the piezo-ceramic piece installed inside the handpiece of the generator, and the piezo-ceramic piece converts electrical energy into vibrational mechanical energy, amplifying and transmitting this energy to the electrode. 

The tip of the electrode vibrates in high frequency at a rate of 55.5 kHz. This energy is used to incise or stop bleeding. 

Generator is used with disposable hand-controlled electrosurgical electrodes.
