[0002] Radiotherapy refers to the local treatment by radiation to eliminate and radically cure the primary focus or metastatic focus of local tumors; the radiation therapy devices used include rays generated by isotopes, electron beams, proton beams generated by X-ray therapy machines or accelerators, etc.; radiotherapy is as effective as surgical treatment for treating various malignant tumors, and can preserve organ function and achieve a radical cure effect. Because of its wide adaptability and good curative effect, it is an ideal choice for many early-stage tumor patients who cannot undergo surgical treatment; usually, positioning is required before radiotherapy to ensure the accuracy of the tumor position. Because the tumor position is unclear, the tumor moves, the patient's body position changes, respiratory movement, large bone mobility, etc., the tumor position may change. Taking the change of the patient's body position as an example, the change of the patient's body position may cause the positional relationship between the tumor and normal tissues to change, which will affect the accuracy of radiotherapy. Therefore, it is necessary to position the patient's body position and the radiotherapy position before radiotherapy. However, at present, in practice, doctors use the fixing frame on the radiotherapy instrument to position the patient's body position. Due to the installation form of the fixing frame on the instrument, when using it, doctors need to disassemble and install the fixing frame on the instrument back and forth for patients of different heights, and then install it according to the patient's body position, which is very inconvenient to use.

Specific embodiments

[0024] The following will further explain the technical solutions of the present invention in conjunction with the attached Figures 1 - 3 ,:

[0025] As Figures 1 - 3 shown, a simple temporary positioning device for assisting patients in radiotherapy, on both sides of the radiotherapy bed board 1, several positioning modules for pressing against the neck and shoulders, arms, and calves are slidably provided respectively. That is to say, there are three positioning modules slidably arranged on both sides of the radiotherapy bed board, and these three groups of positioning modules are respectively used to press against the main marked parts of the patient's shoulders, arms or forearms, and calves, and the patient's body position is fixed by the three-point marking method.

[0026] As Figure 1 shown, at the same time, there are a head placement area identifier 2, an arm placement area identifier 3, and a calf placement area identifier 4 on the radiotherapy bed board 1 respectively. That is to say, the areas on the radiotherapy bed board are marked with different colors respectively. For example, the head placement area identifier is marked in red, the arm placement area identifier is marked in yellow, and the calf placement area identifier is marked in blue. Through different colors, it is convenient for patients to adjust their positions by themselves, which helps the subsequent doctor quickly locate and limit the patient's body position.

[0027] It should be noted that the head placement area identifier 2, the arm placement area identifier 3, and the calf placement area identifier 4 can be respectively drawn and marked with head, arm, and calf graphics for the convenience of patients to distinguish.

The function of the first telescopic rod is to adjust the height of the second telescopic rod, and the function of the second telescopic rod is to adjust the length of the attaching portion extending outwards;

[0034] That is, the length and height of the extending-out portion close to the object can be adjusted through the first telescopic rod 11 and the second telescopic rod 12.

[0035] A connecting sleeve is movably sleeved on the upper part of the first telescopic rod 11, and the second telescopic rod 12 is arranged through the connecting sleeve. The first telescopic rod 11 and the second telescopic rod 12 are vertically distributed. That is to say, the second telescopic rod can rotate circumferentially around the first telescopic rod through the connecting sleeve, and then the whole attaching portion can be driven to rotate circumferentially synchronously.

[0036] Specifically, as Figure 3 shown, the attaching portion 8 includes a patch. An arc-shaped rubber sticker is arranged on the front surface of the patch, and a hinge seat is arranged on the back surface of the patch. A connecting head is movably arranged in the hinge seat. A universal ball head is arranged at the end of the second telescopic rod, and the universal ball head is movably arranged in the connecting head. That is to say, the universal ball head arranged at the end of the second telescopic rod is movably arranged on the patch, that is, the patch can rotate in multiple directions around the end of the second telescopic rod. That is, the patch is adjusted according to patients of different heights and postures to meet different use requirements.
