Abstract

(57) [Summary] [Structure] In an electron beam guide of a radiotherapy device that performs electron beam therapy through incisional surgery on the treated area, there is a guide tooth 2 that is placed in contact with the treated area, and an intermediate tooth that moves in the axial direction of the guide teeth 2. 4, and the intermediate teeth 4 are configured to slide on the irradiation teeth 3 in the axial direction. [Effects] Since the guide tooth which can be moved in the axial direction is provided outside the intermediate tooth and can be placed in direct contact with the affected area, the effect is that the positioning of the affected area can be performed accurately and easily, and the danger to the patient is reduced.

Description

[Detailed explanation of the idea]

0001

[Industrial application field]

The present invention relates to intraoperative electron beam irradiation teeth for radiation therapy equipment, especially for the treatment of the affected area. This invention relates to intraoperative electron beam irradiation tools for open surgery and electron beam therapy.

0002

[Conventional technology]

Conventionally, this type of electron beam irradiation teeth was composed of one tooth.

0003

[Problem that the idea aims to solve]

The conventional electron beam irradiation teeth mentioned above are made of one piece, so they cannot be used for incisional surgery. When inserting into the affected area, move the treatment bed and treatment device body and perform positioning operations. It was extremely difficult because of the Also, the depth of the affected area varies, so pressure may be applied to the affected area. Special precautions were required to avoid risks such as exposure.

0004

[Means to solve the problem]

The intraoperative electron beam irradiation tools of the radiation therapy device of this invention are placed in contact with the treated area. It includes a guide tooth and an irradiation tooth that moves in the axial direction of the guide tooth. configured.

【Example】

Next, the present invention will be explained with reference to the drawings.

[0006] Figures 1, 2, and 3 are cross-sectional views showing the configuration of one embodiment of the present invention, and Figures 4 and 5 are the actual FIG. 6 is an explanatory diagram showing the usage status of this embodiment. FIG. 6 is an explanatory diagram showing the installation status of this embodiment.

[0007] In Fig. 1, the irradiation teeth 3 are inserted into the finder section 6, and the intermediate teeth 4 are inserted. As shown in FIG. 3, the patient 9 on the treatment bed 10 is moved upward by sliding in the axial direction as shown in FIG. The radiation therapy apparatus main body 8 and the irradiation head part 7 are inserted into the guide tubes 2 inserted into the part 11. , and the treatment bed 10, positioning is performed by bringing them closer and moving them up and down. Koto The current state is generally as shown in Figure 2. In addition, on the contrary, as shown in Fig. 1, the intermediate teeth 4 With the irradiation tool inserted into the affected area 11, move the irradiation tool 3 up and down while approaching the finder. It is also possible to insert it into the main part 6.

[0008] In addition, when attaching the irradiation teeth 3 to the finder section 6 as shown in Figure 1, , Gradually lower the finder part 6 and press the fixing lever when it fits on the irradiation tooth 3. -5 to fix it. Also, as shown in Figure 5, there is a reflector in the finder section. The structure is convenient for bringing the affected area to the center of the irradiation area.

[0009] Furthermore, although the drawing shows only one intermediate tool, multiple tools are connected to each other. It is also possible to assemble them one on top of the other so that they slide in the axial direction, and then expand and contract. It is also possible to adopt a structure in which the distance between the source and the irradiation section can be increased or decreased.

0010

[Effect of the idea]

As described above, according to the present invention, the irradiation teeth are doubled and slid, and further guided. By providing teeth, positioning to the affected area can be done accurately and easily. This has the effect of reducing the risk to patients.
