15. A high frequency surgery apparatus comprising:
-
a high frequency current generation section that generates a high frequency current to be transmitted to a living tissue to be operated on; an impedance detection section that detects an electric impedance of the living tissue to which the high frequency current is transmitted via a high frequency treatment instrument; an impedance variation calculation section that calculates an electric impedance variation per predetermined time from the electric impedance value detected by the impedance detection section; an output control section that performs output control on the high frequency current transmitted to the living tissue; and a time measuring section that measures an output time of the high frequency current to the living tissue from the high frequency current generation section, wherein the output control section performs output control of the high frequency current so that the impedance variation calculated by the impedance variation calculation section falls within a predetermined range and stops the output of the high frequency current upon judging that the output time measured by the time measuring section exceeds a first threshold and judging that the electric impedance value detected by the impedance detection section exceeds a second threshold. - View Dependent Claims (16)
