Abstract
A high-frequency operation apparatus includes a grasping portion for grasping a treatment target living tissue, an electrode for supplying a high-frequency current to the living tissue, a high-frequency current supplying section that generates the high-frequency current necessary for treatment, a cable section that transmits the high-frequency current, an impedance measuring section for measuring an impedance value of the living tissue, a detecting section that detects that the impedance value reaches an impedance threshold at a time when moisture in the living tissue starts to evaporate, a measuring section that measures an output time of the high-frequency current after the detection, a storing section that stores a set time, and an output control section that performs control for stopping an output when the output time of the high-frequency current reaches the stored set time.
