Abstract
A treatment device includes a vibrator capable of ultrasonically vibrating, a front mass portion having a first resonance frequency and connected to the vibrator in a manner capable of transmitting ultrasonic vibration, a treatment probe configured to treat a subject and having a second resonance frequency that is higher than the first resonance frequency of the front mass portion, and a connection portion connecting a distal end surface of the front mass portion and a proximal end surface of the treatment probe by a pressing force, and serving as an antinode position when vibrating at the first resonance frequency.

A treatment device comprising:
- a vibrator capable of ultrasonically vibrating;
- a front mass portion having a first resonance frequency and connected to the vibrator in a manner capable of transmitting ultrasonic vibration;
- a treatment portion probe for treating a subject and having a second resonance frequency that is higher than the first resonance frequency of the front mass portion;
- and
- a connection portion connecting a distal end surface of the front mass portion and a proximal end surface of the treatment portion probe in a non-threaded manner by a pressing force, and serving as an antinode position when vibrating at the first resonance frequency, wherein
- the treatment device satisfies a relationship of the first resonance frequency<the second resonance frequency<the first resonance frequency+1.5 kHz.
A treatment portion probe for treating a subject, which, in a manner capable of transmitting ultrasonic vibration, is connected to a vibrator capable of ultrasonically vibrating, and has a second resonance frequency that is higher than a first resonance frequency of a front mass portion having the first resonance frequency, wherein
- a proximal end surface of the treatment portion probe is connected to a distal end surface of the front mass portion in a non-threaded manner by a pressing force, and serves as an antinode position when vibrating at the first resonance frequency.
