Abstract: In an ultrasonic probe a tapered section in which a sectional area perpendicular to a longitudinal axis decreases from a proximal side toward a distal side is provided on the distal side with respect to a probe main body section. When the probe main body section and the tapered section vibrate in an established frequency range, a most distal vibration node positioned most distally among vibration nodes is positioned on the proximal side with respect to a proximal end of the tapered section, and a ⅛ wavelength of the vibration is smaller than a taper dimension from the proximal end the tapered section to a distal end of the tapered section in a longitudinal axis direction.

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.

The through-hole extends from a first outer surface to a second outer surface facing in an opposite direction to that of the first outer surface. The concave portions include a first concave portion on the first outer surface, and a second concave portion on the second outer surface. The treatment portion includes a blade formed along an edge of an opening of the through-hole or the first concave portion.

Abstract: A vibrating body unit includes a vibration generator, a vibration transmitter and first amplitude enlarger. The vibration generator generates ultrasonic vibration whose amplitude has a predetermined correlation with a frequency. The vibration transmitter has a proximal end and a distal end while the vibration generator is attached from a proximal side, and transmits the ultrasonic vibration to a distal side in a longitudinal axis direction. At least one first amplitude enlarger is provided in the vibration transmitter, and enlarges the amplitude of the ultrasonic vibration at a first amplitude enlargement rate in a direction of transmission of the ultrasonic vibration, the first amplitude enlargement rate having a correlation with the frequency opposite to the predetermined correlation.
