An ultrasonic surgical instrument that comprises a handpiece configured to treat living tissue with at least one of an ultrasonic vibration and a high-frequency current, a first generation unit configured to generate a drive current for producing the ultrasonic vibration, a second generation unit configured to generate the high-frequency current, a suction device configured to draw mist produced at the living tissue when the handpiece treats the living tissue with the ultrasonic vibration, and a control unit configured to control the suction device, causing the section device to draw the mist when outputs of both the first generation unit and the second generation unit are detected or when only the output of the first generation unit is detected. The apparatus further comprises a suction tube connected to the suction device, a suction path communicating with the suction tube, and a suction port made in the suction path.
