Title: ULTRASONIC PROBE
Abstract:
This ultrasonic probe has a treatment unit. The treatment unit has a polygonal, substantially polygonal, elliptical or substantially elliptical projected shape when the base side is observed from the tip side along the longitudinal axis of the treatment unit, and comprises: a cutting unit which, by the treatment unit being moved in a direction along the longitudinal axis in a state in which ultrasonic vibration is transmitted to the probe main body, forms a hole based on the aforementioned projected shape in a bone, and a discharge unit which discharges cutting debris of the bone cut by the cutting unit towards the base side from the cutting unit.
