Abstract

A treatment method which treats a living tissue using an ultrasonic device includes making the ultrasonic device come in contact with the living tissue in a state where the product of a pressing force of the ultrasonic device to the living tissue, an amplitude of an ultrasonic vibration caused by the ultrasonic device, and a resonance frequency of the ultrasonic device becomes a predetermined value, and excising the living tissue in a state where the ultrasonic device is in contact with the living tissue.

First claim

What is claimed is:

1. A treatment method for treating a living tissue by using an ultrasonic device, comprising:
making the ultrasonic device come in contact with the living tissue in a state where a product of a pressing force of the ultrasonic device to the living tissue, an amplitude of an ultrasonic vibration caused by the ultrasonic device, and a resonance frequency of the ultrasonic device becomes a predetermined value;
notifying a user when a product of the pressing force, the amplitude, and the resonance frequency is equal to or more than 4700 (N μm kHz); and
excising the living tissue in a state where the ultrasonic device is in contact with the living tissue.

2. The treatment method according to claim 1 , wherein the predetermined value is 4700 (N μm kHz).

3. The treatment method according to claim 1 , wherein the ultrasonic device comprises a sensor for detecting the pressing force, the method further comprising:
adjusting a magnitude of the amplitude or the resonance frequency in accordance with the pressing force detected by the sensor so that a product of the pressing force, the amplitude, and the resonance frequency becomes equal to or more than 4700 (N μm kHz).
