Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a support band for a heating treatment applicator, and more particularly to a support band for a microwave cancer treatment applicator that tightly fixes the microwave transmission surface of the applicator to the surface of a patient.

It is known that when malignant tumors such as cancer are heated at 43 to 45°C for a certain period of time, cancer cells die and other treatments become more effective. Therefore, heating therapy is performed to increase the temperature inside the living body using, for example, dielectric loss caused by microwaves, and an applicator is used to transmit heating treatment microwaves to tumors scattered within the living body. It will be done.

Such an applicator needs to continue transmitting microwaves toward the affected area for a certain period of time until the affected area inside the living body is heated to a predetermined temperature. Therefore, the applicator is supported for a certain period of time with its microwave transmission surface in close contact with the body surface of the living body.

Conventionally, such an applicator has been supported as shown in FIG. That is, the applicator support fitting 12 was rotatably mounted on the stand arm 10, and the applicator 14 was fixed to the tip of the applicator 12. The rotating position of the support fitting 12 is fixed with the microwave transmitting surface of the applicator 14 in close contact with the body surface of the patient 16 on the treatment table, and the microwave transmitting surface of the applicator 14 is in close contact with the body surface of the patient 16. It was held in a fixed position.

However, if the treatment time is long, it becomes difficult for the patient to keep his or her body in a fixed position. For this reason, microwave treatment, for example,
If the treatment continues for a long time, the position of the affected area and the applicator 14 may shift due to movement of the patient's body, etc. In such a case, the microwave will not be transmitted to the affected area and sufficient therapeutic effect will not be achieved. There was a problem that I couldn't do it.

The present invention was developed in view of these conventional problems, and its purpose is to prevent misalignment between the microwave transmission surface of the applicator that uses microwaves to heat the affected area and the surface of the affected area. It is an object of the present invention to provide a support band for a microwave cancer treatment applicator that can exhibit an effective therapeutic effect even when the treatment time is long.

In order to achieve this purpose, the support band of the applicator for microwave cancer treatment according to the present invention has a fixing hole that allows the tip of the applicator that uses microwaves to heat the affected area to protrude toward the patient. a fixing part for bringing the microwave transmitting/receiving surface into contact with the affected body surface; a band made of a stretchable material;
The present invention is characterized by comprising a fixture for tightly fixing the microwave transmitting/receiving surface to the affected body surface and attaching the band to the patient.

Next, a preferred embodiment of the present invention will be described. Note that the same reference numerals are given to the members corresponding to those shown in FIG. 1, and the explanation thereof will be omitted.

FIG. 2 shows a preferred embodiment of the support band of the microwave cancer treatment applicator according to the present invention.

This support band 20 is wrapped around a patient in the same way as a normal band, and is attached to the patient's body surface by fixing fixing devices 22 provided at both ends of the band. In the embodiment, a magic band is used as the fixture 22 to facilitate attachment and detachment of the support band 20 to and from the patient.

This support band 20 includes a fixing part 24 that supports and fixes the microwave transmission surface of the applicator.
is provided, and by attaching the support band 20 to the patient, the microwave transmission surface of the applicator supported and fixed to the fixing part 24 is fixed in close contact with the patient's body surface. In the embodiment, the fixing portion 24 is formed with an applicator fixing hole 24a into which the microwave transmission surface of the applicator is inserted and fixed.

In this embodiment, the applicator support band 20 thus formed is further made of a stretchable band material so as to be stretchable.
As a result, the length of the support band 20 can be freely expanded and contracted, and it can be worn regardless of the patient's body shape.
Since it is attached to the patient with appropriate tension, the attachment position will not shift.

Furthermore, when cancer treatment is applied to the chest or abdomen, the internal volume of the band in the chest or abdomen changes due to breathing, but the elastic support band 20 prevents the above-mentioned fluctuations in the internal volume of the band. This means that the microwave transmitting/receiving surface can be closely fixed to the body surface with sufficient correspondence.

The present invention consists of the above configuration, and its operation will be explained next.

First, as shown in FIG.
An applicator 14 is rotatably attached to the top via a support fitting 12. And this applicator 1
The microwave transmitting surface of No. 4 is supported and fixed to the fixed part 24 of the support band 20 according to the present invention, and the support band 20 is attached to the patient 16, with this microwave transmitting surface located on the surface of the affected body part of the patient 16.

Thereby, the position of the wave transmission surface of the applicator 14 is fixed in close contact with the surface of the affected body of the patient 16. Therefore, even if the patient 16 moves slightly during the heating treatment using the microwaves transmitted from the applicator 14 for a long time, the microwave transmission surface that transmits the microwaves remains fixed on the surface of the affected body of the patient 16. The microwaves are always directed towards the affected area and the treatment is performed effectively.

Furthermore, the support band 20 of this embodiment is formed to be elastic and can be easily attached to the patient 16 using the Magic Band (registered trademark) 22, so it can be easily attached and detached according to the affected area of the patient 16. It is convenient to do.

As described above, according to the present invention, the microwave transmission surface of the applicator that uses microwaves to heat the affected area can be closely fixed to the body surface of the affected area of the patient. Alternatively, even if the internal volume of the band changes or the treatment time is long and the patient moves, misalignment between the microwave transmission surface and the affected body surface can be reliably prevented. It can exert sufficient therapeutic effect.
