Abstract: An ultrasonic treatment instrument for articulations has a bone abrasion mode in which vibration is performed at a first frequency and a first amplitude, and a cartilage dissolution mode in which vibration is performed at a second frequency which is higher than the first frequency, and a second amplitude which is less than the first amplitude, wherein a first vibration velocity, which is a product of the first frequency and the first amplitude, and a second vibration velocity, which is a product of the second frequency and the second amplitude, coincide or substantially coincide.

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 surgical system for treating cartilage includes an output unit, a transducer, an excision unit, and a controller. The output unit generates a driving power. The transducer is connected to the output unit. The transducer converts the driving power into ultrasonic vibration. The excision unit is in contact with a predetermined portion of the cartilage. The excision unit heats the predetermined portion of the cartilage by energy converted based on the driving power. The excision unit excises the cartilage by receiving pressure by an operator while being in contact with the cartilage. The controller controls the driving power output from the output unit so that the predetermined portion of the cartilage is heated to a temperature of 120° C. or higher within 2.2 seconds.

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.
