Abstract: A ligament fixation method can include forming a bone tunnel to a predetermined depth from a surface of a bone; mounting a reconstruction ligament to the ligament fixation device. The reconstruction ligament can be disposed along outer surfaces of plate-like pressing segments of a ligament fixation device and an outer surface of a connection segment that connects the pressing segments. The method can also include inserting the ligament fixation device into the bone tunnel from the connection-segment side; fastening a screw to a receiving section of the ligament fixation device from an opening of the ligament fixation device to increase a distance between the pair of pressing segments and to compress the reconstruction ligament between each pressing segment and an inner surface of the bone tunnel; and fixing the reconstruction ligament to the bone by causing a part of the screw to dig into the bone.

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.

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 elbow joint surgical treatment includes transmitting an ultrasonic vibration to a treating portion of an ultrasonic device to excise the treated object region of the synovial membrane, and bringing the treating portion of the ultrasonic device, used in excising the synovial membrane, to come in contact with an osteophyte positioned in one of a coronoid fossa of a humerus, an olecranon fossa of the humerus, a coronoid process of an ulna, and an olecranon. The surgical treatment includes transmitting an ultrasonic vibration to the treating portion in contact with the osteophyte to remove the osteophyte.

Abstract: In an arthroendoscopical surgical method, a resection target area, and a freshening treatment area which becomes repair surfaces with bleeding, are identified, and a resection line and a freshening line are drawn on a tear site in a meniscus, which is emphasized by fluorescence with use of a fluorescent medicine under excitation light. 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 and freshening line under visible-light illumination. Thus, an inclined resection surface is formed, and planar repair surfaces with bleeding are joined and repaird.

Abstract: A contact portion, provided in an exposed surface of the treating section, treats a treated object by a transmitted ultrasonic vibration while intruding into the treated object toward an intruding direction from a state being in contact with the treated object. An index portion is disposed on an anti-intruding direction side with respect to the contact portion in the exposed surface. The index portion becomes an index indicating an intruding amount of the contact portion into the treated object toward the intruding direction. The index portion includes index surfaces arranged in the intruding direction, and each of the index surfaces has an angle relative to the intruding direction which is different from the angle of the adjacent index surface.
