ABSTRACT:
An ultrasound treatment system in accordance with the present invention comprises: ultrasonic transducers for generating ultrasonic vibrations; a handpiece including the ultrasonic transducers and serving as an operation unit; a probe connected to the ultrasonic transducers and serving as a vibration conveyer for conveying ultrasonic transducers to a distal member constituting a stationary section of a treatment unit used to treat a living tissue; a sheath serving as a protective member for shielding the probe; a holding member opposed to the distal member at the distal end of the sheath and constituting a movable section of the treatment unit which clamps a living tissue in cooperation with the distal member; a manipulator to be handled for clamping or freeing a living tissue using the holding member and distal member; an operation member for driving the holding member responsively to a movement of the manipulator; and a turning mechanism for turning the treatment unit relative to the manipulator with the axial direction of the ultrasonic transducers as a center.
