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 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.

Abstract: An arthroscopic surgery method for ankle ligament reconstruction of this embodiment is removed using an ultrasonic treatment tool, blowing away a synovial membrane, and secures the view for a remnant ligament. Then, bone holes are produced to a fibula, a talus and a calcaneus using the ultrasonic treatment tool.

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: A joint surgical treatment includes bringing a treating portion of an ultrasonic device into contact with a damaged region of a cartilage that is a treated object region in the joint, and transmitting an ultrasonic vibration to the treating portion in contact with the treated object region while observing the treated object region with the arthroscope to remove the treated object region of the cartilage. The ultrasonic vibration is used to remove the treated object so as to smoothly continue a removed surface from which the treated object region is removed and a non-removed surface adjacent to the removed surface without forming any corners between the surfaces in the cartilage.

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.
