Abstract: A medical ultrasound device includes: an ultrasound generator and an elongated probe. A cross-sectional surface of the probe at a distal end to which ultrasound oscillation is propagated is perpendicular to a longitudinal direction of the probe, and the cross-sectional surface has a shape identical to a shape of a cross-sectional surface of an anchor to form, in a bone, a bottomed hole for placing the anchor and having a shape to prevent rotation of the anchor in the bottomed hole. An area of the cross-sectional surface of the probe at the distal end is larger than an area of a cross-sectional surface of the probe at a proximal end. The distal end includes a treatment portion that expands outward relative to the proximal end and that is formed in a first direction perpendicular to the longitudinal direction and in a second direction different from the first direction.

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: 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.
