Surgical operation system and surgical operation method

摘要

The surgical operation system includes a treatment section for treating a living tissue of a treatment target; an ultrasound generation section for providing ultrasound to the treatment section; an ultrasound drive power supply section for supplying ultrasound drive power to generate ultrasound to the ultrasound generation section; a high-frequency power supply section for supplying high-frequency power to the treatment section; an impedance detection section for detecting the impedance of the ultrasound provided to the living tissue and the impedance of the high-frequency power supplied to the living tissue; and a control section for controlling the ultrasound energy amount and the amount of high-frequency power or a crest factor value thereof in response to the detected impedance values of ultrasound and high-frequency wave.
