Furthermore, the handpiece 1 has an ultrasonic transmitter consisting of a horn 3 and a probe 4, and the horn 3 amplifies the ultrasonic vibrations of the ultrasonic transducer 2, and the probe 4 amplifies the ultrasonic vibrations of the ultrasonic vibrator 2. The information is transmitted to the target organization 5.

A patient plate 6 is brought into contact with the tissue 5 to be treated.

On the other hand, 7 is an ultrasonic drive circuit that emits an ultrasonic signal for driving an ultrasonic transducer. The ultrasonic vibrator 2 is connected to the output end of the ultrasonic drive circuit 7 via switches 8a and 8b.

Further, the hand piece 1 is connected to one of the output ends of the high frequency drive circuit 10 via the active cord A and the switch 9.

A patient plate 6 is connected to the other output end of the high frequency drive circuit 10 via a patient cord P.

The high frequency drive circuit 10 emits a high frequency signal for high frequency ablation, and this high frequency drive circuit 10. The active cord A, the patient cord P, and the patient plate 6 constitute a high-frequency ablation means that supplies a high-frequency signal for high-frequency ablation to the probe 4.

20 is a foot switch circuit, and a plurality of foot switches 21, 22, 23 and a switch drive circuit 24 are connected to this foot switch circuit 20.

That is, the foot switch circuit 20 operates the switch drive circuit 24 depending on the state of the foot switches 21, 22, 23.
It gives control commands to the

The switch drive circuit 24 drives the switches 8a, 8b and switch 9 in accordance with control commands from the foot switch circuit 20.

Here, the foot switch circuit 20 and the switch drive circuit 24 constitute a control means that selectively or alternately executes the high-frequency ablation of the high-frequency ablation means and the drive of the ultrasonic drive circuit 7.

Next, the operation of the above configuration will be explained with reference to FIG. 2.

When a treatment start operation is performed using an operation unit (not shown), the ultrasonic drive circuit 7 operates to emit an ultrasonic signal, and the high-frequency drive circuit 10 operates to emit a high-frequency signal.

In this state, when the foot switch 21 is pressed,
The switches 8a and 8b are turned on by the foot switch circuit 20 and the switch drive circuit 24.

When the switches 8a and 8b are turned on, an ultrasonic signal emitted from the ultrasonic drive circuit 7 is applied to the ultrasonic transducer 2 of the node piece l. As a result, the ultrasonic transducer 2 generates ultrasonic vibrations, and the ultrasonic vibrations are transmitted to the treatment target tissue 5 via the horn 3 and the probe 4.

Therefore, ultrasound treatment therapy can be performed.

Further, when the foot switch 22 is depressed, the switch 9 is turned on by the foot switch circuit 20 and the switch drive circuit 24.

When the switch 9 is turned on, a high frequency signal emitted from the high frequency drive circuit 10 is transmitted to the horn 3. It flows through the probe 4 and the patient plate 6 to the tissue 5 to be treated.

Therefore, radiofrequency ablation treatment can be performed.

Further, when the foot switch 23 is depressed, the switches 8a, 8b and the switch 9 are turned on alternately by the foot switch circuit 20 and the switch drive circuit 24.

When the switches 8a and 8b are turned on, as described above, an ultrasonic signal is applied to the ultrasonic transducer 2, ultrasonic vibration is generated, and the ultrasonic vibration is transmitted to the paper a5 to be treated, thereby performing ultrasonic treatment.

When the switch 9 is turned on, a high frequency signal flows to the tissue 5 to be treated, and high frequency ablation treatment is performed.

In this way, by alternately performing the ultrasound treatment and the high-frequency ablation treatment, the effects of both treatments can be maximized.

For example, if a blood vessel is damaged and bleeding occurs when unnecessary tissue such as a tumor is removed by ultrasonic treatment, immediate measures can be taken to stop the bleeding and coagulate it.

Next, a second embodiment of the invention will be described with reference to FIG.

As a result, the ultrasonic transducer 2 generates ultrasonic vibrations, and the ultrasonic vibrations are transmitted to the treatment target tissue 5 via the horn 3 and the probe 4.

Therefore, ultrasound treatment therapy can be performed.

Further, when the foot switch 22 is depressed, the high frequency drive circuit 10 operates according to a command from the drive control circuit 30.

In this way, as shown in FIG. 5, a high frequency signal is emitted from the high frequency drive circuit 10, which is transmitted to the horn 3 and

Further, when the foot switch 23 is depressed, the ultrasonic drive circuit 7 is burst-driven in response to a command from the drive control circuit 30, and the high-frequency drive circuit 10 is operated between burst drives.

In this way, as shown in FIG. 6, ultrasonic signals and high frequency signals are alternately emitted.

Therefore, the ultrasound treatment and the high-frequency ablation treatment are performed alternately, and the effects of both treatments can be maximized.

For example, if a blood vessel is damaged and bleeding occurs when unnecessary tissue such as a tumor is removed by ultrasonic treatment, immediate measures can be taken to stop the bleeding and coagulate it.

The storage and reading of the image memory 44 is controlled by a control section 45, and a CRT display 46 is further connected to the control section 45.

Note that when inserting the probe 4 into the electronic endoscope 40, the support part 47 attached to the electronic endoscope 40 is

On the other hand, 50 is a switch control circuit that controls the switches 8a, 8b, and 9.43, and this switch control circuit 50 controls the high-frequency ablation of the high-frequency ablation means and the driving of the ultrasonic drive circuit 7 selectively or alternately. It functions as a means.

The operation of the above configuration will be explained with reference to FIG.

In this state, the switch control circuit 50 sequentially turns on the switches 8a, 8b, switch 9, and switch 43.

When the switches 8a and 8b are turned on, an ultrasonic signal is applied to the ultrasonic transducer 2 to generate ultrasonic vibrations, which are transmitted to the tissue 5 to be treated and perform ultrasonic treatment.

When the switch 9 is turned on, a frequency signal flows to the tissue 5 to be treated, and high frequency ablation treatment is performed.

When the switch 43 is turned on, images captured by the lens 41 and CCD 42 of the electronic endoscope 40 are supplied to the image memory 44. The supplied image is appropriately stored in the image memory 44 under the control of the control section 45. Further, the images stored in the image memory 44 are appropriately displayed on the CRT display 46 under the control of the control section 45.

In this way, by alternately performing the ultrasound treatment and the high-frequency ablation treatment, the effects of both treatments can be maximized. Moreover, since the state of the tissue that changes with each treatment can be observed sequentially using the electronic endoscope 40, appropriate treatment can be performed.
