Abstract: A medical ultrasound device includes: an ultrasound generator and an elongated probe. A cross-sectional surface of the probe at a distal end to which ultrasound oscillation is propagated is perpendicular to a longitudinal direction of the probe, and the cross-sectional surface has a shape identical to a shape of a cross-sectional surface of an anchor to form, in a bone, a bottomed hole for placing the anchor and having a shape to prevent rotation of the anchor in the bottomed hole. An area of the cross-sectional surface of the probe at the distal end is larger than an area of a cross-sectional surface of the probe at a proximal end. The distal end includes a treatment portion that expands outward relative to the proximal end and that is formed in a first direction perpendicular to the longitudinal direction and in a second direction different from the first direction.

Abstract: An ultrasonic probe includes a treatment portion that has a through-hole or concave portions. The through-hole extends from a first outer surface to a second outer surface facing in an opposite direction to that of the first outer surface. The concave portions include a first concave portion on the first outer surface, and a second concave portion on the second outer surface. The treatment portion includes a blade formed along an edge of an opening of the through-hole or the first concave portion. An outer relay surface extends from the blade to the second outer surface and faces away from a center axis of the through-hole or the concave portions. A distance from the center axis to the blade is greater than or equal to a distance from the center axis to the outer relay surface at a position between the blade and the second outer surface.

Abstract: An ultrasound probe includes a probe body, and a treatment unit. The treatment unit includes: a cutter that is provided at a distal end part of the treatment unit and that cuts the bone according to move of the treatment unit along a longitudinal axis in a state where ultrasonic vibration is being transmitted to the probe body; and a path that is provided in the treatment unit and through which debris of a bone that is cut by the cutter are discharged along the longitudinal axis toward a proximal end side with respect to the cutter. The path includes a first opening that is provided in a distal end surface of the cutter; and a second opening that is provided in a side surface part of the treatment unit, wherein the path allows the first opening and the second opening to communicate.

Abstract: An arthroscopical surgical method using an ultrasonic treatment device for a joint includes: transmitting ultrasonic vibration to a treatment portion of the ultrasonic treatment device, removing an injured region of an articular cartilage so that a subchondral bone is exposed, and forming a cartilage edge which is nearly angled at 90° with the exposed surface of the subchondral bone to form a pool-shaped depression; forming a hole which pierces up to a cancellous bone of the subchondral bone through the depression, and scratching blood vessels in the cancellous bone; causing bleeding from the blood vessels so that blood is retained in the depression via the hole.

Abstract: A guiding device can include a guide including a through hole for insertion of an ultrasound probe that forms a tunnel to a bone. The guide can be configured to guide movement of the ultrasound probe inserted through the through hole; an offset portion offset from an axis of the through hole. The guiding device can also include an offset portion with an abutment portion configured to abut to an outer wall of the bone, on a side on which the through hole is located, in a direction orthogonal to the axis and a bone-tunnel introduction portion provided on an opposite side to the side on which the through hole is located and being configured to be inserted into the tunnel. The bone-tunnel introduction portion can have a sectional polygon shape smaller than a polygon on an inner circumferential face of the through hole.

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 guiding device includes: a guide having a tubular shape. The guide can include a first through hole for insertion of an ultrasound probe. The guide can be configured to guide movement of the ultrasound probe inserted through the first through hole. A protrusion can protrude from one end of the guide and can have a sectional shape that corresponds to a sectional shape of the distal portion of the ultrasound probe, the sectional shape of the protrusion being orthogonal to an axis of the first through hole, and the sectional shape of the distal portion of the ultrasound probe being orthogonal to the axis of the first through hole.
