Abstract

A treatment apparatus for operation is configured to operate in a plurality of output modes. A hand piece is provided with a probe configured to supply a high-frequency current, and an ultrasonic transducer which is connected to the probe and activates ultrasonically the probe. A high frequency driving circuit supplies a high-frequency current to the probe. An ultrasonic transducer driving circuit drives the ultrasonic transducer. An operation switch selects a first output mode and a second output mode. A controller controls a high-frequency output from the high frequency driving circuit and an ultrasonic output from the ultrasonic transducer driving circuit, to operate the treatment apparatus for operation in an output mode selected by the operation switch.

Claims

1. A treatment apparatus for operation operable in a plurality of output modes comprising:

a hand piece provided with a probe capable of supplying a high-frequency current, and an ultrasonic transducer connected to the probe for ultrasonically activating the probe;

a high frequency driving circuit for supplying a high-frequency current to the probe;

an ultrasonic transducer driving circuit for driving the ultrasonic transducer;

an operation switch for selecting a first output mode and a second output mode; and

a controller which controls a high-frequency output from the high frequency driving circuit and an ultrasonic output from the ultrasonic transducer driving circuit, for operating the treatment apparatus for operation in an output mode selected by the operation switch.

2. The treatment apparatus for operation according to claim 1, wherein the operation switch is composed of a two-step operation switch configured to be set to a first operation position and a second operation position.

3. The treatment apparatus for operation according to claim 2, wherein the controller operates the treatment apparatus for operation in the first output mode when the operation switch is set to the first operation position, and operates the treatment apparatus for operation in the second output mode when the operation switch is set to the second operation position.

4. The treatment apparatus for operation according to claim 3, wherein the first output mode is a high-frequency output mode to output a high-frequency signal from the high frequency driving circuit, or an ultrasonic output mode to output an ultrasonic signal from the ultrasonic transducer driving circuit;

and the second output mode is an output mode combining the high-frequency output mode and the ultrasonic output mode.

5. The treatment apparatus for operation according to claim 1, further comprising a fluid supply unit for supplying fluid to the hand piece, and a suction unit for collecting fluid from the hand piece.

6. The treatment apparatus for operation according to claim 5, wherein the first and second output modes include a fluid supply/suction output mode to control a fluid supply output of the fluid supply unit and/or a suction output of the suction unit;

and the operation switch includes an operation switch for setting the fluid supply/suction output mode.

7. A hand piece used in a treatment apparatus for operation operable in a plurality of output modes, comprising:

a probe capable of supplying a high-frequency current;

an ultrasonic transducer which is connected to the probe, and ultrasonically activates the probe; and

an operation switch for selecting a first output mode and a second output mode,

wherein a high-frequency output from a high frequency driving circuit for supplying a high-frequency current to the probe, and an ultrasonic output from an ultrasonic transducer driving circuit for driving the ultrasonic transducer are controlled so as to operate the treatment apparatus for operation in an output mode selected by the operation switch.
