摘要：
An ultrasound probe includes: a probe main body section to which ultrasonic vibration generated by an ultrasound transducer is transmitted； a controller that is connected to the ultrasound transducer and controls generation of the ultrasonic vibration； and a treatment section that is provided on a distal side of the probe main body section and forms a hole in a bone, which is a treatment target, with the ultrasonic vibration. The treatment section has a distal end and a proximal end and includes a columnar portion, a cutting portion that cuts the bone by crushing the bone with the ultrasound vibration and forms the hole, and a discharge portion that discharges cutting debris of the bone cut by the cutting portion toward the proximal end from the cutting portion, the discharge portion including a recessed portion formed in a groove shape inclined with respect to the longitudinal axis.
