摘要： The electric surgical operation apparatus of the present invention easily and securely shortens the rising time until incision and coagulation effects appear even if electrodes having different volumes or surface areas are used for the treatment tool. Cutting sharpness and safety are improved and the operation time is shortened. In the electric surgical operation apparatus, contact of a monopolar electrode of a monopolar treatment tool with organic tissue is detected by a voltage or current sensor. Based on a detection signal therefrom, a high-frequency output is supplied at a predetermined value from a high-frequency cautery power source device, and a high-frequency output is supplied at a higher initial setting value than the predetermined value during an initial period at a rising time. Setting of at least one of the initial period and the initial setting value can be changed.

摘要： In an electrosurgery apparatus for treating a living tissue, while the living tissue is being treated, a variation in state of energy supplied from a cautery power supply to a monopolar treatment device is detected on the basis of detection data obtained from a current sensor and a voltage sensor. Based on the detected variation, living body information on the living tissue to be treated is obtained.
