Abstract: An ultrasonic probe transmits vibration along longitudinal axis from the proximal toward the distal end, including: first area including proximal and distal end portions, a center axis parallel to the longitudinal axis, the first area having a vibration antinode position at the distal end, wherein maximum distance from the center axis to an outer peripheral surface in radial direction orthogonal to the center axis is a first distance; a treatment section located on a distal end side's barycenter position displaced from the center axis; a second area located between the first area and treatment section continuous with the distal end of the first area and gravity center axis parallel to the center axis to pass through the barycenter, wherein maximum distance from the center axis to the outer surface in the radial direction orthogonal to the center axis is a second distance equal to or shorter than the first distance.

Abstract: An ultrasonic probe that transmits an ultrasonic vibration, generated in an ultrasonic vibrator, from a proximal end to a distal end so that the ultrasonic probe performs a longitudinal vibration in a vibrating direction. The ultrasonic probe including a probe body, a distal asymmetric portion, and a proximal side probe component. The distal asymmetric portion is asymmetric about an X-axis so that a center of gravity of the distal asymmetric portion is deviated from the X-axis and a first lateral vibration of the distal asymmetric portion is superposed on the longitudinal vibration of the ultrasonic probe. The proximal side probe component is bent relative to the probe body at a bending position so that a center of gravity of the proximal side component is deviated from the X-axis and a second lateral vibration of the proximal side component is superposed on the longitudinal vibration of the ultrasonic probe.

Abstract: A distal side transmitting member of an ultrasonic transmitting unit includes a projecting portion protruding from a distal side abutment portion toward a proximal direction, and a proximal side transmitting member includes a depressed portion depressed from a proximal side abutment portion toward the proximal direction. A cavity portion having a space is formed between a protruding end of the projecting portion and a bottom portion of the depressed portion inside the proximal side transmitting member when the depressed portion is engaged with the projecting portion, and one of antinode positions of an ultrasonic vibration is located within a range from the protruding end to the bottom portion.
