Abstract: In an ultrasonic probe, a curved portion gravity center of a probe curved portion located on a first perpendicular direction side with respect to a longitudinal axis. A boundary position between a probe relay portion and a probe main body portion is located on a distal side with respect to a reference antinode position which is located most distally among antinode positions of a longitudinal vibration located on a proximal direction side with respect to the probe curved portion. By a cross-section changing portion located at the boundary position, a cross section gravity center in a cross section of the probe relay portion perpendicular to the longitudinal axis is away from the longitudinal axis toward a second perpendicular direction opposite to the first perpendicular direction.

Abstract: Provided is a method of manufacturing a vibration transmission member for an ultrasonic treatment tool. The method includes: applying a release agent between a surface of a vibration transmission member configured to transmit ultrasonic vibration and a die for hot forging; performing hot forging to form the vibration transmission member after the applying of the release agent; removing, after the performing of the hot forging, a part of an oxide film formed in the performing of the hot forging by a first surface treatment; performing pickling to remove the oxide film after the removing of the part of the oxide film by a blasting treatment; and performing coating with a resin after the performing of the pickling.

Abstract: A vibration transmission member includes a main body, a treatment portion that is provided at the distal end of the main body, a first covering formed of a material that has an electrical insulating property and has a thermal conductivity lower than a thermal conductivity of the main body, which covers a part of a surface of the treatment portion, and a second covering formed of a material that has an electrical insulating property and has a thermal conductivity lower than the thermal conductivity of the main body. The second covering is integrally formed with at least a part of the first covering and varies in thickness in a circumferential direction of the main body. The second covering includes a first area and a second area in the circumferential direction, such that a thickness dimension of the first area is smaller than a thickness dimension of the second area.

Abstract: Each of segments of a vibration transmitting member has a dimension of a half-wave length between mutually neighboring vibration anti-nodes and sets a vibration node as a center. In each of recess segments included in the segments, the vibration node is located in a groove, and an intermediate extension extends from a proximal end to a distal end in the groove in a longitudinal direction. At least two of the recess segments are different from each other with respect to at least one of a dimension in the longitudinal direction of the intermediate extension and a cross-sectional area perpendicular to the longitudinal direction of the intermediate extension.

Abstract: An insertion instrument includes a shaft projecting, by being inserted through a hole of a fixing instrument, from a distal end of the fixing instrument toward a distal side, and a gas supply channel formed in the shaft section and having a jet port, which jets a gas, in a distal portion of the shaft section. The gas is supplied from a proximal side to the distal side toward the jet port in the gas supply channel, and an extension dimension along the longitudinal axis from the jet port toward the proximal side is greater than an extension dimension of the hole of the fixing instrument.
