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 ultrasonic surgical includes an output unit, a transducer, a probe, 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 probe transmits the ultrasonic vibration. The excision unit is provided in the probe. The excision unit is in contact with a predetermined portion of the cartilage. The excision unit heats the predetermined portion of the cartilage by ultrasonic vibration 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, 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 repaired.

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 ultrasonic surgical system includes an ultrasonic transducer, a probe, and at least one circuit. The ultrasonic transducer is designed to ultrasonically vibrate. The probe is coupled to the ultrasonic transducer and is designed to treat a living tissue by the ultrasonic vibration. The circuit performs functions including detecting a pressing force of the probe against the living tissue, calculating a value of a product of the pressing force, an amplitude of the ultrasonic vibration, and a resonance frequency of the probe, comparing the calculated value with a predetermined product value, and generating a predetermined signal based on a result of the comparison.
