Abstract

An ultrasonic surgical operation instrument characterized by comprising a treating section for treating living tissues using ultrasonic vibrations, a heat sensor disposed in the treating section for detecting the temperature of the treating section, and a control unit for controlling the temperature of the treating section on the basis of temperature information detected by the heat sensor.

Claims

1. An ultrasonic surgical operation instrument, comprising:

a treatment unit for performing treatments on a living tissue using ultrasonic vibrations;

a heat sensor that is disposed in the treatment unit and that detects a temperature of the treatment unit; and

a control unit for controlling the temperature of the treatment unit on the basis of the temperature information detected by the heat sensor.

2. The ultrasonic surgical operation instrument according to claim 1, wherein:

on the basis of the temperature information detected by the heat sensor, the control unit controls the temperature of the treatment unit such that the temperature is kept at the prescribed temperature at which living tissue coagulates.

3. The ultrasonic surgical operation instrument according to claim 2, wherein:

on the basis of the temperature information detected by the heat sensor, the control unit controls the temperature of the treatment unit by controlling an amplitude of the ultrasonic output provided to the treatment unit, by controlling cooling by feeding air or water to the treatment unit, or by controlling a grasping force of the treatment unit.

4. An ultrasonic surgical operation instrument, comprising:

a treatment unit that includes an ultrasonic probe for giving treatment to a living tissue using ultrasonic vibrations and a jaw for grasping the living tissue between the jaw and the ultrasonic probe;

a heat sensor that is disposed in the treatment unit and that detects a temperature of the treatment unit; and

a control unit for controlling the temperature of the treatment unit on the basis of the temperature information detected by the heat sensor.

5. The ultrasonic surgical operation instrument according to claim 4, wherein:

the control unit controls the temperature of the treatment unit such that the temperature is kept at the prescribed temperature at which a living tissue coagulates on the basis of the temperature information detected by the heat sensor.

6. The ultrasonic surgical operation instrument according to claim 5, wherein:

on the basis of the temperature information detected by the heat sensor, the control unit controls the temperature of the treatment unit by controlling an amplitude of the ultrasonic output for driving the ultrasonic probe, by controlling cooling by feeding air or water to the treatment unit, or by controlling the grasping force between the ultrasonic probe and the jaw for grasping living tissue.
