1. An ultrasonic operating apparatus comprising:
- an ultrasonic oscillator to generate ultrasonic oscillation;
an oscillation transmitting member for transmitting ultrasonic oscillation, which is made by a bar-like body having a distal end and a proximal end, the proximal end connected to the ultrasonic oscillator;
a sheath which is made by a cylindrical body having a distal end and a proximal end, and inserted onto the oscillation transmitting member;
a jaw which is provided at the distal end of the sheath, and grasps a living tissue in a clearance to the distal end of the oscillation transmitting member;
a control unit which is provided at the proximal end of the sheath, and opens/closes the jaw with respect to the distal end of the oscillation transmitting member; and
an instruction unit which detects that the jaw is closed by the control unit, and instructs the ultrasonic oscillator to output oscillation energy to generate ultrasonic oscillation when the jaw is closed.

4. An ultrasonic operation apparatus comprising a medical ultrasonic handpiece to cut and coagulate by using ultrasonic oscillation, the handpiece comprising:
-
an ultrasonic oscillator to generate ultrasonic oscillation; an oscillation transmitting member for transmitting ultrasonic oscillation, which has a proximal end connected to the ultrasonic oscillator; a grasping unit held openable\closable in a clearance to the distal end of the oscillation transmitting member; a grasping control unit which opens/closes the grasping unit, and grasps a living tissue between the grasping unit and the distal end of the oscillation transmitting member by closing the grasping unit with respect to the distal end of the oscillation transmitting member; and an instruction unit which corresponds to the states of the grasping control unit, and instructs to output oscillation energy from the ultrasonic oscillator in the state that a living tissue is grasped between the grasping unit and the distal end of the oscillation transmitting member. - View Dependent Claims (5)
