Title: ULTRASONIC TREATMENT TOOL FOR JOINTS AND ULTRASONIC TREATMENT SYSTEM FOR JOINTS
Abstract:
An ultrasonic treatment tool for joints that has: a bone cutting mode wherein the treatment tool vibrates at a first frequency and a first amplitude; and a cartilage dissolving mode wherein the treatment tool vibrates at a second frequency that is higher than the first frequency and a second amplitude that is smaller than the first amplitude. A first vibration speed that is the product of the first frequency and the first amplitude coincides or substantially coincides with a second vibration speed that is the product of the second frequency and the second amplitude.
