Patent ID: 8574228

Claim:
An ultrasonic incision or coagulation apparatus comprising: an ultrasonic transducer for generating ultrasonic vibrations; an ultrasonic-transducer-driving power supply that supplies an ultrasonic-transducer-driving current to the ultrasonic transducer, thereby driving the ultrasonic transducer; a probe having conductivity and extended in an axial direction, the probe being operatively coupled to the ultrasonic transducer to allow transmission of ultrasonic vibrations generated by the ultrasonic transducer; a clamp member having conductivity and disposed to be operable to open and close with respect to the probe to hold a living tissue between the clamp member and the probe to incise or coagulate the living tissue; an operating handle adapted to operate opening or closing actions of the clamp member; a transmitter that transmits an operating force, in accordance with an operation amount of the operating handle, to the clamp member; and a high-frequency power supply which is electrically coupled to the probe and the clamp member, and which supplies a high-frequency current between the probe and the clamp member to perform treatment to the living tissue; a signal output section which outputs an operation signal to the ultrasonic-transducer-driving power supply and the high-frequency power supply; and a control section which controls, based on the operation signal outputted from the signal output section, the ultrasonic-transducer-driving power supply, and the high-frequency power supply so as to provide one of (I) a first state of simultaneously supplying both of the ultrasonic-transducer-driving current and the high-frequency current, or (ii) a second state of supplying only one of the ultrasonic-transducer-driving current and the high-frequency current.
