Problems solved by technology

[0004] Radiotherapy positioning devices include human body fixing frame, positioning film and other devices. The patient can maintain the position required for treatment by lying on the human body fixing frame. However, since the position of the chest tumor is relatively close to the heart, when the heart continues to beat, the position of the tumor will continue to change. Changes, resulting in indeterminate radiation exposure sites, which can easily cause unnecessary damage to normal tissues
The positioning film is made of low-temperature thermoplastic material, which can be softened by heating in hot water at 65-75°C for 2-3 minutes. The softened positioning film is stretchable and can be directly shaped on the body of a radiotherapy patient. The soft body parts are molded into a fixed shape to maintain the stability of local positions, but they do not fix the whole human body. Once the position of the human body changes, it will also lead to changes in the radiation-irradiated parts, causing unnecessary damage to normal tissues
[0005] Therefore, the problem in the prior art is that there is a lack of a fixed and high-precision breast tumor positioning device.

Embodiment 1

[0042] A positioning board for chest tumor treatment, see Figure 1-3 , including body immobilization devices and partial immobilization devices. The body immobilization device is used to fix the patient's body and reduce the patient's large-scale activities. The local immobilization device is used to fix the patient's chest shape and reduce the change of the tumor position caused by the patient's breathing or movement. .

[0043] The body fixing device comprises a base plate 1, and the base plate 1 is provided with a groove 11 conforming to the physiological shape of the human body. The groove 11 has a head, neck, chest, waist and limbs, etc., and the patient can lie in the groove 11. 11 is provided with an elastic limiter 12, the elastic limiter 12 is an elastic airbag, an inflatable airbag or elastic cotton; the elastic limiter 12 is used to be clamped between the patient and the inner wall of the groove 11, and the elastic limiter 12 The elastic force of the elastic force...

Embodiment 2

[0049] A positioning board for chest tumor treatment, basically the same structure as in Example 1, the difference is: see Figure 4-5 , the soft net 4 is made of elastic material, and its size in a natural state is smaller than the chest size of the patient, such as a rectangle with a length of 20 cm and a width of 18 cm, which includes a retractable frame 40 of elastic material and a plurality of flexible tubes 401 of elastic material. A plurality of hoses 401 are arranged in a criss-cross pattern in the shrinkable frame 40, and all the hoses 401 are not connected. There is a pull rope 402, and the two ends of the pull rope 402 pass through the respective hoses 401, and the two ends of the pull rope 402 are respectively connected with retractable rope assemblies.

[0050] The retractable rope assembly includes a power assembly, a connecting rod 404, a plurality of pressure sensors and a controller, and the power assembly includes a plurality of take-up wheels 403 and a plura...

Embodiment 3

[0056] A positioning board for chest tumor treatment, the structure is basically the same as that of Example 2, the difference is:

[0057] see Figure 6 , the power assembly includes a plurality of take-up pulleys 403, a plurality of rotating motors (the rotating motors can adopt the same rotating motor structure as in Embodiment 2), two bus wheels 405 and a plurality of connecting rods 406; they are arranged on the fixed assembly 2 The take-up wheels 403 are not provided with rotating motors, these take-up wheels 403 only have a guiding effect, and each fixed assembly 2 is provided with a bus wheel 405, and the end of the pull rope 402 on the same side as the bus wheel 405 goes around it After the corresponding take-up pulley 403, it is finally connected on the bus pulley 405, and a rotating motor is arranged on the bus pulley 5. The rotating motor is used to control the rotation of the bus pulley 405, and then drives a plurality of pull cords 402 to expand or tighten up. T...

Abstract

The invention belongs to the technical field of auxiliary medical equipment, and particularly relates to a positioning plate for chest tumor treatment. The positioning plate comprises a body fixing device and a local fixing device. The body fixing device comprises a bottom plate, a groove is formed in the bottom plate, and an elastic limiting component is arranged in the groove; and the local fixing device comprises a fixed assembly, a guide assembly and a movable assembly, the fixed assembly is arranged on the bottom plate, scale marks are arranged on the guide assembly, the movable assembly comprises a soft net, a hand pull rope is arranged on the soft net, and soft film sticking rings are respectively arranged on the inner surface of the soft net at positions corresponding to the positions of the breasts of the groove. The body fixing device is used for fixing the body of a patient, the local fixing device is used for fixing the shape of the chest of the patient, tumor position changes caused by breathing or moving of the patient are reduced, the fixing precision is high, long-time starting of ray irradiation equipment is avoided, and energy can be saved.

Description

technical field [0001] The invention belongs to the technical field of auxiliary medical equipment, and in particular relates to a positioning board for chest tumor treatment. Background technique [0002] Chest tumors, as the name suggests, are tumors that grow in the chest, such as breast tumors. Breast tumors are lumps that occur in the breast. Its main etiology and pathogenesis are excess of the seven emotions, stagnation of liver and lung qi, liver and lung suffering from pathogenic factors, resulting in failure of liver, lung and spleen deficiency, qi stagnation and phlegm coagulation, or aging and physical weakness, imbalance of Chong and Ren, resulting in qi over time. Stagnant blood stasis, blocked meridians, knot in the breast to form. According to the nature of the tumor, it can be mainly divided into benign tumors or malignant tumors. Benign tumors refer to tumors without the ability to infiltrate and metastasize. Tumors often have capsules or clear boundaries, ...
