Abstract: A guiding device can include a guide including a through hole for insertion of an ultrasound probe that forms a tunnel to a bone. The guide can be configured to guide movement of the ultrasound probe inserted through the through hole; an offset portion offset from an axis of the through hole. The guiding device can also include an offset portion with an abutment portion configured to abut to an outer wall of the bone, on a side on which the through hole is located, in a direction orthogonal to the axis and a bone-tunnel introduction portion provided on an opposite side to the side on which the through hole is located and being configured to be inserted into the tunnel. The bone-tunnel introduction portion can have a sectional polygon shape smaller than a polygon on an inner circumferential face of the through hole.

Abstract: A guiding device includes: a guide having a tubular shape. The guide can include a first through hole for insertion of an ultrasound probe. The guide can be configured to guide movement of the ultrasound probe inserted through the first through hole. A protrusion can protrude from one end of the guide and can have a sectional shape that corresponds to a sectional shape of the distal portion of the ultrasound probe, the sectional shape of the protrusion being orthogonal to an axis of the first through hole, and the sectional shape of the distal portion of the ultrasound probe being orthogonal to the axis of the first through hole.

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.
