Abstract
An ultrasonic surgical system enables connection of a hand switch as well as a foot switch, which is used to operate a driving signal generator, without the necessity of retrofitting a main unit including the driving signal generator used to drive an ultrasonic transducer incorporated in a connected handpiece. An extension unit is included for connecting the foot switch and hand switch to the main unit. The foot switch and hand switch are connected to the main unit via the extension unit.
