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: The disclosed technology is directed to an ultrasonic probe comprises a probe main portion configured to transmit ultrasonic vibration generated by an ultrasonic transducer. A treatment portion is configured on a distal side of the probe main portion along a longitudinal axis thereof. The treatment portion includes first direction surfaces disposed in a first direction intersecting the longitudinal axis and second direction surfaces that are adjacent to the first direction surfaces and are disposed in a second direction different from the first direction surfaces. The first direction surfaces further includes a plurality of surfaces formed into a staircase shape when being viewed from the treatment portion and one or more surfaces formed into a staircase shape when being viewed from a side opposed to the distal side of the treatment portion. The second direction surfaces further includes a plurality of surfaces formed into a staircase shape toward the distal side.

Abstract: An ultrasound probe includes a probe body, and a treatment unit. The treatment unit includes: a cutter that is provided at a distal end part of the treatment unit and that cuts the bone according to move of the treatment unit along a longitudinal axis in a state where ultrasonic vibration is being transmitted to the probe body; and a path that is provided in the treatment unit and through which debris of a bone that is cut by the cutter are discharged along the longitudinal axis toward a proximal end side with respect to the cutter. The path includes a first opening that is provided in a distal end surface of the cutter; and a second opening that is provided in a side surface part of the treatment unit, wherein the path allows the first opening and the second opening to communicate.

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 ultrasonic probe includes a first bent extending portion provided on a distal side with respect to a narrowed portion and extending in such a state as to bend toward a first crossing direction side crossing a longitudinal axis, and a second bent extending portion continuous with the distal side of the first bent extending portion and extending in such a state as to bend toward second crossing direction side opposite to the first crossing direction. The second bent extending portion includes a blade portion, and in a projection seen from the distal side, the first bent extending portion and the second bent extending portion are located within a minimum inside diameter of a sheath.

Abstract: An ultrasonic probe includes a probe main body section; and a curved extending section which is extended in a state of curving relative to the probe main body section toward a first intersecting direction side. The curved extending section includes a first curved outer surface facing the first intersecting direction side, and a second curved outer surface facing a second intersecting direction side. A first curve start position at which the first curved outer surface starts curving relative to the longitudinal axis toward the first intersecting direction side is positioned on the distal side with respect to a second curve start position at which the second curved outer surface starts curving relative to the longitudinal axis toward the first intersecting direction side.

Abstract: An ultrasonic probe treating a shoulder joint includes a probe main body section extended along a longitudinal axis, and a curved extending section extended in a state of curving relative to the probe main body section toward a first intersecting direction side when a certain direction intersecting the longitudinal axis is defined as the first intersecting direction. The curved extending section includes a first curved outer surface facing the first intersecting direction side, and a second curved outer surface facing a second intersecting direction side when an opposite direction of the first intersecting direction is defined as the second intersecting direction. An acute angle of a tangent line at a distal end of the second curved outer surface relative to the longitudinal axis direction is 20° or more and 25° or less.

Abstract: An energy supplier of an ultrasonic treatment system can output an electric power in a first output mode and a second output mode in which the electric power supplied to a drive force generation unit during a unit time is higher than in the first output mode. A controller maintains an output state of the electric power in the first output mode when a judgment section judges that a load on an ultrasonic probe is less than or equal to a threshold, and switches the output state of the electric power to the second output mode when the judgment section judges that the load is more than the first threshold.

Abstract: A vibration transmitter includes: a proximal end extending portion; a supported portion; a distal end extending portion; a first relay unit provided between the supported portion and the proximal end extending portion; and a second relay unit provided between the supported portion and the distal end extending portion. The second relay unit includes a horn that is constructed such that an outer diameter at a position continuously adjacent to the supported portion is larger than: (i) an outer diameter of the first relay unit at a position continuously adjacent to the supported portion, and (ii) the outer diameter of the distal end extending portion. The horn expands amplitude of vibration output from a distal end of the distal end extending portion to be larger than a maximum amplitude at an antinode of vibration in the first relay unit or the proximal end extending portion.

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.
