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 including administering a fluorescent chemical agent into a joint, which is a treatment target, allowing the fluorescent chemical agent to be adsorbed by a degenerated region that has degenerated from a normal region in a cartilage inside the joint, which is the treatment target, displaying and observing an emission of fluorescence from the degenerated region, which has adsorbed the fluorescent chemical agent, by infrared excitation light on a display through an arthroscope, and allowing a surgeon to recognize the degenerated region in the cartilage inside the joint, which is the treatment target.

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: An ultrasonic transmitter unit includes: a sheath that forms a cylindrical shape and is having a proximal end and a distal end; an ultrasonic transmitter configured to be inserted into the sheath; and a cover member that covers a part of the ultrasonic transmitter and has an inner surface and an outer surface. The ultrasonic transmitter includes: a first area surrounded by the sheath; a second area protruding from the distal end of the sheath; and a distal-end treatment portion provided in a distal end of the second area. The cover member covers the second area of the ultrasonic transmitter, and exposes the distal-end treatment portion of the ultrasonic transmitter to an outside, and is made of fluorine-based resin.

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 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 ultrasound probe includes: a probe main body section to which ultrasonic vibration generated by an ultrasound transducer is transmitted; a controller that is connected to the ultrasound transducer and controls generation of the ultrasonic vibration; and a treatment section that is provided on a distal side of the probe main body section and forms a hole in a bone, which is a treatment target, with the ultrasonic vibration. The treatment section has a distal end and a proximal end and includes a columnar portion, a cutting portion that cuts the bone by crushing the bone with the ultrasound vibration and forms the hole, and a discharge portion that discharges cutting debris of the bone cut by the cutting portion toward the proximal end from the cutting portion, the discharge portion including a recessed portion formed in a groove shape inclined with respect to the longitudinal axis.
