Title:
VIBRATION TRANSMITTING MEMBER AND ULTRASONIC TREATMENT TOOL
Document Type and Number:
WIPO Patent Application WO/2018/087841
Kind Code:
A1
Abstract:
This vibration transmitting member transmits ultrasonic vibration, and is provided with a straight part which extends along a longitudinal axis, and a curved part which curves with respect to the straight part in a direction crossing the longitudinal axis. The outer surface of the curved part comprises a first curved surface facing the direction of curvature of the curved part, and a second curved surface facing the direction opposite of the direction of curvature of the curved part. The first curved surface has a first section which extends in the direction opposite of the direction of curvature of the curved part with respect to an imaginary curved surface defined to pass through the first curved surface at the curve start position of the curved part and to be parallel to the second curved surface. In the first section, the distance between first curved surface and the imaginary curved surface increases from the base side towards the distal side.
