Abstract: An ultrasonic probe can include a probe main body that receives ultrasonic vibration generated by an ultrasonic transducer and a treatment unit disposed on a distal end of the probe main body. The treatment unit can include a resection portion and a guide unit that each have a projected shape when viewed along a longitudinal axis of the ultrasonic probe. The resection portion can resect a bone that needs to be treated along a resection direction. The guide unit can protrude from the resection portion on a distal end of the treatment unit. The guide unit can also help to maintain the resection direction relative to a central axis of the hole.

Abstract: A surgical procedure of preparing bone holes to fix an implanted tendon to a femur when performing reconstruction of a ligament in a knee joint, includes: bringing a treatment portion of an ultrasonic treatment instrument into contact with the femur in the knee joint, and applying ultrasonic vibration from the treatment portion to the femur, thereby cutting and forming a first bone hole from the inside of the knee joint to the femur in a predetermined depth.

Abstract: A surgical procedure of preparing bone holes to dispose an implanted tendon to a femur when performing reconstruction of a ligament in a knee joint, includes: forming a first bone hole in the femur; and applying ultrasonic vibration from a treatment portion of an ultrasonic treatment instrument to the femur, thereby cutting and expanding the first bone hole from the inside of the knee joint to the first bone hole of the femur along a predetermined depth, and forming a second bone hole having a polygonal shape, an approximately polygonal shape, an elliptical shape or an approximately elliptical shape to receive the implanted tendon.

Abstract: An ultrasound device includes: an ultrasound generator; an ultrasound probe; and a distal end treatment portion capable of forming a bone hole when pressed against a bone. The distal end treatment portion includes a base portion, and a distal end portion. The distal end portion includes projections and a valley portion between adjacent projections. Each projection is formed of at least one excision surface that is inclined from a base of the projection to a distal top of the projection. The excision surface is capable of finely crushing the bone. The valley portion includes a valley peak at a distal-most meeting point of adjacent projections such that a surface of the valley extending distally from a point at which the valley meets an outer surface of the base portion to the valley peak is inclined.
