Disclosed herein is a surgical operation apparatus which comprises a tip member for outputting ultrasound vibration and/or high-frequency coagulation current, a handpiece provided with the tip member, a circuit for supplying the high-frequency coagulation current to the tip member and a circuit for supplying the ultrasound vibration to the tip member. The surgical operation apparatus includes an ultrasound vibration mode for mainly fragmenting tissue in a surgical operation region by outputting the ultrasound vibration from the tip member, and a coagulation mode for mainly performing hemostasis of the tissue by outputting the high-frequency coagulation current from the tip member. The ultrasound vibration mode and the coagulation mode are switchable by a control device, wherein during the coagulating mode, a predetermined coagulation mode ultrasound vibration is also supplied to the tip member, thereby suppressing the tissue from being burnt to be stuck to the tip member.
