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: 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: Provided is a scanning endoscope system including: an illumination-light emitting portion that is inserted into a body of a patient and that emits illumination light emitted from a light-source portion toward an imaging subject in the body in a spot-like manner; a light scanner that scans the illumination light on the imaging subject; and a light detector that is disposed at a body surface of the patient, and that detects reflected light coming from the scanning position in the imaging subject, at which the illumination light is scanned by the light scanner.

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 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: In an arthroendoscopical surgical method, a resection target area, which is emphasized by fluorescence with use of a fluorescent agent under excitation light, is identified on a meniscus, and a resection line or an imaginary resection line is drawn. Using an ultrasonic treatment tool and an arthroscope, the resection target area is resected by a probe which generates ultrasonic vibrations, based on the resection line or imaginary resection line under visible-light illumination, and an inclined resection surface is formed.
