As shown in FIG. 5, the warming device remote control section 8 is composed of a temperature display section 37 and an emergency stop switch 38, and heating is performed via a warming apparatus remote control section connection cable 9. The temperature information measured by the device body 1 (including the temperature measured by the temperature sensor 34 at the distal end portion 7 of the intracavity applicator) is displayed on the temperature display portion 37, and the emergency stop switch 38 is pressed to heat the temperature. The heating function of the apparatus main body 1 can be stopped, or all the functions of the heating apparatus main body 1 can be stopped.

Next, the operation of the hyperthermia device constructed as described above will be described. First, the intracavity applicator 2 is connected to the warming device body 1, the air in the cooling water conduit system is evacuated, and then the balloon 34 of the intracavity applicator 2 is deflated. In that state, the intracavity applicator 2 is inserted into the body cavity of the patient 6. The brachysource guide tube 11 may be put into the brachysource insertion hole 23 of the intracavitary applicator 2 before inserting the intracavitary applicator 2 or after being inserted into the patient 6, whichever is a problem. There is no.

After inserting the intracavity applicator 2 into the body cavity of the patient 6, cooling water is circulated in the balloon 34 to make the balloon 3
Inflate 4. As a result, the surface of the balloon 34 comes into close contact with the inner surface of the body cavity of the patient 6, and the inner cavity applicator tip 7 is fixed in the body cavity.

After that, the heating apparatus main body 1 is set and the heating is started. The operations up to this point are performed on the operation panel 15 of the heating device body 1. The monitor 14 of the heating apparatus body 1 displays various handling instructions, various measured values, information indicating the state of the apparatus, and the like. During heating, the measured temperature value, the heating time, the content of any error, etc. are displayed.

When the temperature becomes stable, the operator goes out of the inside A of the radiation treatment room. The heating device main body 1 needs to have an automatic heating temperature control function. The operator uses the brachytherapy device remote control unit 12 located outside the radiation treatment room B to move the brachytherapy device main body 10 to the brachytherapy source guide tube 1.
The brachysource 33 is fed into the body cavity of the patient 6 via 1. The brachysource guide tube 11 is inserted into the brachysource insertion hole 23 of the intracavity applicator 2, and the brachysource 33 is positioned at the intracavity applicator tip 7 as shown in FIG. In this state, intracavitary irradiation is performed for a predetermined time, and then the brachytherapy device 33 is collected by the brachytherapy device body 10.

During irradiation of the affected area by the small radiation source 33, the operator cannot enter the inside of the radiation treatment room A to prevent exposure.
During that time, the measured temperature such as the heating portion, its peripheral portion, and the body temperature is displayed on the temperature display portion 37 of the heating device remote operation portion 8 as the state of the patient due to the heating treatment by the heating device main body 1. The displayed temperature always includes the temperature measured by the temperature sensor 35 provided on the distal end portion 7 of the intracavity applicator. The warming device main body 1 has a mechanism for automatically controlling the high frequency output to control the temperature, and since it also has various other protective devices built-in, basically, the warming device can be heated without any additional operation. Warm therapy is continued. However, patient 6
If there is a sudden change in the condition, the measured temperature becomes higher than expected due to some abnormality, and there is no protection, or if the operator judges that the heating treatment should be stopped immediately, the affected area is irradiated. During this time, the warming treatment cannot be stopped by operating the warming device body 1. In that case, by pressing the emergency stop switch 38 of the heating device remote control unit 8, the heating of the heating device main body 1 is stopped, or all the functions (not only heating but also cooling water recirculation and cooling) are performed. (Including water temperature control) can be stopped.

If there is no abnormality during the irradiation of the affected area, the heating by the heating device body 1 is continued after the irradiation, and the heating is automatically ended when a predetermined heating time elapses. As a result, during simultaneous use of heating and irradiation, the operator does not enter the radiation treatment chamber A and is exposed to radiation, and the patient temperature, which is important in heating treatment, such as the measured temperature of the affected part during heating, is stored. The operator can monitor outside B of the treatment room, and the heating treatment can be stopped from outside B of the radiation treatment room based on the information and the like.

Although the embodiment of the combination of the intracavity heating device and the brachytherapy device is shown here, the present invention is not limited to this. A combination of the heating device and the brachytherapy device, or a combination of the external heating device and the external irradiation treatment device may be used. However, since the features of the present invention are utilized in the simultaneous combination of the heating treatment and the radiation treatment, the combination using the intracavity heating device is a combination of the external heating device (especially a large one including the bed). It will certainly be more realistic than in some cases.

Display of information output from 0, high-frequency heating treatment device 53
Remote control unit 61 for outputting the emergency stop command of
The remote control unit 61 is connected to the high frequency heating device 53 and the monitor 60 by a cable 62.

FIG. 12 is a block diagram of the ninth embodiment, in which a controller 70 for controlling heating treatment, a high frequency oscillator 71 for supplying a high frequency current, a matching circuit 72 for matching the impedance of the load and the high frequency oscillator 71, Extracorporeal applicator 56, intracavity applicator 57 serving as an electrode for supplying high-frequency current to the living body, intracavity applicator 57 and temperature sensor 58 for detecting the temperature of the living body, remote emergency for urgently stopping generation of high-frequency current from a remote part Stop switch 73
It is composed of

The control unit 70 takes in temperature information from the temperature sensor 58, calculates a high frequency output to be supplied to the intracavity applicator 57, and issues an output command to the high frequency oscillator 71 to control the heating of the living body. To do. Further, the control unit 70 controls the matching circuit 72 to perform impedance matching between the high frequency oscillator 71 and the extracorporeal applicator 56.

When the operator determines to stop the heat treatment while using the heat treatment apparatus 53 from the remote control unit 61, the remote emergency stop switch 73 outputs a high frequency output stop command to the control unit 70. The control unit 70 stops the output of the high frequency oscillator 71.

The flow until the operator determines that the emergency stop of the heat treatment is necessary will be described below. In the case of the heat treatment alone, while the operator is monitoring the treatment with the remote control unit 61, the patient 55 complains of discomfort such as a feeling of heat and pressure,
Alternatively, the operator recognizes that it is difficult to continue good heat treatment due to abnormal display / matching failure of the temperature sensor 58 due to the positional displacement of the intracavity applicator 57, etc. It is judged that the heat treatment needs to be urgently stopped due to reasons such as not being able to expect proper treatment.

In the case of simultaneous use of radiation, in addition to the above-mentioned reason, a favorable radiation distribution is obtained due to complaints of pain and pressure of the patient 55 due to radiation treatment, or displacement of the intracavity applicator 57. If it is not possible, the operator recognizes that the brachytherapy source for radiation therapy is dropped from the intraluminal applicator 57, and the radiation therapy is stopped urgently because the safety of the patient 55 cannot be ensured and effective treatment cannot be expected. , Judge that an emergency stop of heat treatment is necessary.

Therefore, the high-frequency output can be stopped urgently from the remote control section 61, and the safety of the patient 55 can be ensured. Since the high frequency output is stopped by the control unit 70, the high frequency output can be easily restored.

FIG. 14 is a block diagram of the tenth embodiment, in which a signal line 74 from the remote emergency stop switch 73 to the high frequency oscillator 71 is added to the ninth embodiment.

The operation is basically the same as that of the ninth embodiment. The difference is that the remote emergency stop switch 73 is used when the operator determines that the high frequency output needs to be emergency stopped at the remote operation section 61. The emergency stop signal is directly sent to the high frequency oscillator 71 to stop the high frequency output.

At the same time, the remote emergency stop switch 73 transmits to the control unit 70 that the remote emergency stop is activated, and the control unit 70 recognizes that the high frequency output is in the emergency stop state.

Therefore, the high frequency output can be stopped urgently from the remote control section 61, and the safety of the patient 55 is ensured. The high-frequency oscillator 7 is controlled by the remote emergency stop switch 73.
Since the emergency stop command is directly output to 1, the high frequency output can be surely stopped even if the control unit 70 causes a runaway or the like.

FIG. 15 shows the eleventh embodiment and is an overall configuration diagram of a hyperthermia device in the case where the radiation treatment of intracavitary irradiation and the high frequency heating treatment are simultaneously used. The configuration different from that of the tenth embodiment is that the intracavitary radiation treatment device 64 is provided.
That is, the intracavity irradiation catheter 65 is added. This allows simultaneous use of intracavitary irradiation and heat treatment. Further, preferably, the intraluminal irradiation catheter 65 is fixed to the central axis of the shaft portion inserted into the intracavity of the intraluminal applicator 57, so that the radiation distribution due to the intraluminal irradiation and the heating distribution due to the high-frequency heating treatment. Overlap, and effective treatment is possible.

FIG. 16 is a block diagram of the eleventh embodiment, which is basically the same as the ninth embodiment,
The only difference is the system power supply 7 that supplies power to the device.
5 is provided and the signal line 74 from the remote emergency stop switch 73 is directly connected to the system power supply 75.

The operation is basically the same as that of the ninth embodiment, except that the operator operates the remote control unit 61 in the following manner.
When it is judged that the emergency stop of the high frequency output is necessary, the remote emergency stop switch 73 directly sends an emergency stop signal to the system power supply 75 to bring all the units into the stopped state.
Stop high frequency output completely.

Therefore, the high frequency output can be stopped urgently from the remote control section 61, and the safety of the patient 55 is ensured. By forcibly shutting off the system power supply 75 from the remote emergency stop switch 73, the high frequency output can be surely stopped.
