Abstract: A surgical procedure of preparing bone holes to dispose an implanted tendon to a femur when performing reconstruction of a ligament in a knee joint, includes: forming a first bone hole in the femur; and applying ultrasonic vibration from a treatment portion of an ultrasonic treatment instrument to the femur, thereby cutting and expanding the first bone hole from the inside of the knee joint to the first bone hole of the femur along a predetermined depth, and forming a second bone hole having a polygonal shape, an approximately polygonal shape, an elliptical shape or an approximately elliptical shape to receive the implanted tendon.

Abstract: An ultrasound device includes: an ultrasound generator; an ultrasound probe; and a distal end treatment portion capable of forming a bone hole when pressed against a bone. The distal end treatment portion includes a base portion, and a distal end portion. The distal end portion includes projections and a valley portion between adjacent projections. Each projection is formed of at least one excision surface that is inclined from a base of the projection to a distal top of the projection. The excision surface is capable of finely crushing the bone. The valley portion includes a valley peak at a distal-most meeting point of adjacent projections such that a surface of the valley extending distally from a point at which the valley meets an outer surface of the base portion to the valley peak is inclined.

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 ultrasound probe includes a treatment portion that is formed at a distal end of a probe body that can transmit input vibration energy. The treatment portion can vibrate with a predetermined amplitude to cut a treatment target object. The treatment portion includes: a first striking face that faces in a distal direction along an axial direction of the ultrasound probe; a second striking face that faces in the distal direction at a position on a proximal end side of the first striking face in the axial direction; and a first side surface that connects the first striking face and the second striking face in the axial direction and that has a predetermined length in the axial direction. The first side surface has a length that is equal to or less than an amplitude of vibration of the treatment portion caused by the input vibration energy.

Abstract: An ultrasound treatment tool that includes: a probe that includes a main body and a treating portion; and a first tubular portion. The first tubular portion includes at least one through hole that is formed in a wall of the first tubular portion so as to be in fluid communication with a liquid channel in the first tubular portion, and an opening that is formed at a distal end of the first tubular portion. A total opening area of the through hole(s) is larger than a cross-sectional opening area of the liquid channel at the opening.

Abstract: Ultrasound oscillation can be propagated to a distal end of an elongated probe. A cross-sectional surface of the probe is perpendicular to the length of the probe, and has to the same shape as a shape of a cross-sectional surface of an anchor. The probe is configured to forma bottomed hole in a bone for placing the anchor and the shape of its cross-sectional surface can prevent rotation of the anchor in the bottomed hole. An area of the cross-sectional surface of the probe at the distal end can be larger than an area of a cross-sectional surface of the probe at a proximal end. The distal end of the probe includes a treatment portion that extends outward from a center of the proximal end of the probe in a first direction perpendicular to the longitudinal direction and in a second direction different from the first direction.

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.
