Abstract:
1. An ultrasonic treatment apparatus comprising: an ultrasonic instrument configured to treat a living-body tissue through ultrasonic vibrations; a fluid irrigation unit configured to irrigate a cooling fluid for cooling the ultrasonic instrument to the ultrasonic instrument; a fluid suction unit configured to suck the cooling fluid irrigated by the fluid irrigation unit to the ultrasonic instrument; an ultrasonic driving control unit configured to control the driving of ultrasonic vibrations of the ultrasonic instrument; a mode switching unit configured to select either an irrigation/suction interlocking mode or an irrigation/suction non-interlocking mode; and an irrigation/suction control unit configured to sequentially control the driving of the fluid irrigation unit and the driving of the fluid suction unit after a driving output from the ultrasonic driving control unit has stopped when the irrigation/suction interlocking mode is selected, or when the ultrasonic instrument is an instrument capable of irrigating and sucking the cooling fluid, and configured to not perform the driving of the fluid irrigation unit and the driving of the fluid suction unit after a driving output of the ultrasonic driving control unit has stopped when the irrigation/suction non-interlocking mode is selected, or when the ultrasonic instrument is an instrument incapable of irrigating and sucking the cooling fluid.
