Abstract: An ankle arthrodesis of this embodiment performs a cartilage the ultrasonic treatment procedure using an ultrasonic treatment tool. As one condition, when wear of cartilage has attained to the whole of an ankle, it carries out. A method for ankle arthrodesis is disposal which excises the cracked organization which exists in an ankle using the ultrasonic treatment tool, and fixes a tibia and a talus under it with a screw.

Abstract: An ultrasonic vibration transmittable probe includes a probe body configured to transmit ultrasonic vibration generated by an ultrasonic transducer. A treatment section is provided on a distal end side of the probe body along its longitudinal axis and is configured to cut a treatment object with the ultrasonic vibration. The treatment section includes first to third cutting surfaces disposed at progressively proximal positions. A portion of the first cutting surface has a dimension along a first orthogonal direction orthogonal to the longitudinal axis that is smaller than a dimension of the second cutting surface along the first orthogonal direction.

Abstract: A method of performing a procedure on a meniscus, via an ultrasonic surgical tool. The ultrasonic tool includes a probe capable of transmitting ultrasonic vibration from a proximal end toward a front end. The probe includes a bent portion that is inclined with respect to a longitudinal axis of the probe, and a procedure portion that is disposed at the front end of the probe and has a plurality of cutting surfaces. The method includes: inserting the probe in a body; moving the probe through a space in between the femur and the tibia to position the procedure portion adjacent to the horizontal rupture in the meniscus; positioning a cutting surface of the procedure portion on a posterior portion of the meniscus; and resecting the horizontal rupture along an inclination of the meniscus to form an inclined resection plane.

Abstract: An ultrasound probe includes: a probe main body section to which ultrasonic vibration generated by an ultrasound transducer is transmitted; a controller that is connected to the ultrasound transducer and controls generation of the ultrasonic vibration; and a treatment section that is provided on a distal side of the probe main body section and forms a hole in a bone, which is a treatment target, with the ultrasonic vibration. The treatment section has a distal end and a proximal end and includes a columnar portion, a cutting portion that cuts the bone by crushing the bone with the ultrasound vibration and forms the hole, and a discharge portion that discharges cutting debris of the bone cut by the cutting portion toward the proximal end from the cutting portion, the discharge portion including a recessed portion formed in a groove shape inclined with respect to the longitudinal axis.

Abstract: An endoscopic treatment instrument includes a guide sheath. The guide sheath includes a second distal end, which has an inside diameter to insert the insertion portion therethrough so that the distal end of the insertion portion is configured to protrude relative to the second distal end. The guide sheath is inserted through the guide pipe so that the second distal end is configured to protrude relative to the first distal end of the guide pipe.
