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.

First claim

What is claimed is:

1. An ultrasonic transmitting unit which extends along a longitudinal axis and which is configured to transmit an ultrasonic vibration from a proximal direction toward a distal direction and thereby configured to vibrate at a predetermined resonance frequency, the ultrasonic transmitting unit comprising:
a vibration generating portion which is configured to generate the ultrasonic vibration;
a proximal side transmitting member to which the vibration generatin…
