Abstract
An electrosurgical apparatus in the present invention has a high frequency power generation section which generates high frequency power to be applied to a living tissue, a voltage detection section which detects the voltage of the high frequency power, a current detection section which detects the current of the high frequency power, an impedance computation section which computes the impedance of the living tissue on the basis of the voltage and the current, and a control section which, when the impedance exceeds a predetermined threshold value, performs control for increasing the frequency of the high frequency power stepwise on the high frequency power generation section.
