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 optical-scanning-type observation probe is provided with: an imaging optical system that illumination light scanned by an optical scanner enters and that focuses the illumination light in the form of a spot, multiple times; a projection optical system that emits illumination light coming from a focus position focused by the imaging optical system, toward a subject in the form of a spot; and a light-receiver that is provided independently of the imaging optical system and the projection optical system and that receives reflected light of the illumination light, the reflected light coming from the subject, via a light path different from that of the imaging optical system and the projection optical system.

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 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: An ultrasonic vibration transmittable probe includes a probe body configured to transmit ultrasonic vibration generated by an ultrasonic transducer. A treatment section is provided on a distal end side of the probe body along its longitudinal axis and is configured to cut a treatment object with the ultrasonic vibration. The treatment section includes first to third cutting surfaces disposed at progressively proximal positions. A portion of the first cutting surface has a dimension along a first orthogonal direction orthogonal to the longitudinal axis that is smaller than a dimension of the second cutting surface along the first orthogonal direction.

Abstract: A method of performing a procedure on a meniscus, via an ultrasonic surgical tool. The ultrasonic tool includes a probe capable of transmitting ultrasonic vibration from a proximal end toward a front end. The probe includes a bent portion that is inclined with respect to a longitudinal axis of the probe, and a procedure portion that is disposed at the front end of the probe and has a plurality of cutting surfaces. The method includes: inserting the probe in a body; moving the probe through a space in between the femur and the tibia to position the procedure portion adjacent to the horizontal rupture in the meniscus; positioning a cutting surface of the procedure portion on a posterior portion of the meniscus; and resecting the horizontal rupture along an inclination of the meniscus to form an inclined resection plane.

Abstract: An implant including a screw body composed of pure magnesium or a magnesium alloy and having a male thread, and the implant further including an anodized membrane covering an outer surface of the screw body. The male thread has a clearance flank and a pressure flank. The clearance flank faces forward in a traveling direction and the pressure flank faces rearward in the traveling direction during a screwing process of the screw body. The biodegradation period of the anodized membrane on the clearance flank is shorter than the biodegradation period of the anodized membrane on the pressure flank.

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.
