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: 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: 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.
