Description
Technical Field
The invention relates to the technical field of medical appliances, in particular to a compensation pad integration device for radiotherapy positioning and a using method thereof.
Background
Population and health problems are one of the major problems facing mankind in the 21 st century, and have become a long-term and major strategy in countries around the world. Since the 20 th century and the 80 th era, China has been developing at a high speed for more than 20 years, and economic achievements have attracted attention. With the improvement of living standard and the increase of life per capita, the aging of the population in China is more and more prominent, and the incidence of malignant tumor corresponding to the aging is higher and more. The malignant tumor (cancer) has become one of the main public health problems seriously threatening the health of Chinese population, according to the latest statistical data, the death of the malignant tumor accounts for 23.91 percent of the total death causes of residents, and the morbidity and the mortality of the malignant tumor are in a continuously rising state in recent ten years, the medical cost caused by the malignant tumor exceeds 2200 hundred million every year, and the prevention and control situation is severe.
According to WHO statistics, 55% of cancers are curable (calculated as 5-year survival), 27% of which are cured by surgery, 6% by chemotherapy and 22% by radiotherapy. Radiation therapy is required in the course of disease in 70% -85% of patients with tumors, and thus radiation therapy is one of the main methods of tumor treatment.
Nowadays, radiotherapy technology has entered the "three-essence" era of "precise radiotherapy" (i.e., precise positioning, precise planning, precise treatment). The precision of radiation therapy is not limited to the large-range irradiation of tumors any more, but the accurate positioning and delineation of the tumors, the accurate dosage of rays and the repeatability of treatment are used as important evaluation criteria. However, the problems in the prior art and the idea are improved, and meanwhile, many problems are still solved.
Radiotherapy technology currently has two different irradiation modes, high-energy X-rays and high-energy electron rays, wherein the high-energy X-rays have stronger penetrating power, so that the dosage of the skin surface is relatively lower, and therefore the radiotherapy technology is more used for treating deep tumors. In contrast, high-energy electron beams are more suitable for treating tumors near the skin surface. However, the physical characteristics of the high-energy X-rays, which are about 60% of their maximum dose on the skin surface, and the high-energy electron beams, which are about 80% of their maximum dose, determine that the radiation dose on the skin surface will be low. Therefore, in radiotherapy of the skin surface, high-energy electron beams are generally used. However, even in this case, in order to achieve a sufficient prescribed dose, the dose difference between the surface dose and the deep dose of the human body is very large, which results in a high dose of radiation to the deep part of the human body and a large damage to the normal organs of the human body.
To solve such problems, a material called radiation therapy compensators (radiotherapy compensators) is widely used in the industry at present. The product is made of high polymer thermoplastic elastomer (TPE) powder, liquid paraffin and a transparent polyethylene film, has soft texture and can be attached to the surface of a human body. Meanwhile, the size of the product is generally 30 × 0.3cm, the density is 0.9cm3/g, and the product is similar to human tissues. After the skin care patch is attached to the surface of a human body, the difference between the surface dose and the deep dose of the human body can be greatly shortened, so that normal tissues are protected.
Because the size, position and shape of the tumor of the patient are different, the product can not realize the customized requirement, so that under the condition of larger tumor, a single compensator can not cover all the tumors, and a plurality of compensators are required to cover all the areas. However, in the using process, the radiation therapy course generally lasts for 1-2 months, and the compensators covered on the body surface need to be replaced each time of treatment, but the compensators are made of soft materials, have smooth touch feeling and cannot be easily fixed, so that a plurality of technicians are often required to operate simultaneously. Even so, the superposition of multiple compensators has little repeatability, resulting in a significant deviation of the dose to the surface tumor from the planned irradiation dose. Meanwhile, in the radiation therapy process, CT scanning positioning and accelerator radiation therapy are required, and metal materials can generate artifacts, affect image quality and cause dose deviation, so that a common fixing device cannot integrate and fix a plurality of compensation pads.
At present, most of areas adopt the modes of directly superposing, adhering, fixing, binding and the like of the compensation pads, so that irregular bulges are generated at the superposition positions of the compensation pads, the whole material cannot be completely attached to a patient, a large number of cavities are generated, and the loss of dose building effect is caused. As shown in fig. 1-3, it can be seen from the CT image and CBCT image that the position of the compensation pad cannot be repeated at all, the body surface dose of the radiotherapy of the patient needs to be the same with the position of the compensation pad to ensure the dose is accurate, and the existing compensation pad is overlapped to generate a lot of cavities with the body surface and has completely different positions.
In recent years, a team also proposes that the elastic ropes are fixed in a binding mode, but the phenomenon that the elastic ropes are not placed consistently when the accelerator machine room is reset and CT simulation positioning is also met, because the compensation pad material can be stretched, after the whole bandage is bound, the elastic ropes cannot be stretched accurately every time, meanwhile, under the condition that the body surface is wrapped in a large area, the relevant positions cannot be marked, and the compensation pads are still placed in a mutually overlapped mode.
In addition, there are also methods proposed by teams for performing body surface coverage by 3D printing technology. However, through investigation and research, 3D printing is still only suitable for body position mold manufacturing of small-area tumors at present, and is limited in application of large-area tumors such as full breast tumors, double breast tumors and the like. In addition, the 3D printed mould material is hard, and the patient can not be attached to the mould due to slight changes of the body shape in the whole radiotherapy process, so that the dose building effect is invalid. Meanwhile, 3D printing requires a series of contour sampling for a patient, and requires a certain time for waiting, which is not convenient for a patient with inconvenient movement or acute symptoms.

3) Insert the location of after-fixing board 7 and detain 8 and insert in corresponding through-hole 4 and extend to the top of first compensation pad 1 and second compensation pad 2, place preceding fixed plate 5 at the top of first compensation pad 1 and second compensation pad 2, and detain 8 with the location and insert spacing hole 6 in, detain the top of 8 with the rubber sleeve cover in the location, make preceding fixed plate 5 and after-fixing board 7 fixed each other, press down first compensation pad 1 and second compensation pad 2 around after-fixing board 7 and make first compensation pad 1 and second compensation pad 2 warp to the bottom surface of first compensation pad 1 and second compensation pad 2 and the bottom surface parallel and level formation parcel chamber parcel after-fixing board 7 of after-fixing board 7 and constitute integral compensation pad.
4) And (4) placing the integrated compensation pad in the step (3) on the surface of the human body, so that the smooth and flat first compensation pad 1 and second compensation pad 2 are in contact with the surface of the human body, thereby reducing the discomfort of the patient in the treatment process.
5) The marking points are recorded on the body surface of the patient at the marking holes 9, so that the position is determined during repeated positioning in the whole radiotherapy process.
The first compensation pad 1 and the second compensation pad 2 are spliced and integrated through the front fixing plate 5 and the rear fixing plate 7, and splicing is very convenient. Because the distances among the compensation pads are all fixed, the effect of bulging cannot be generated, so that the whole compensation pad is more attached to the body surface, meanwhile, the compensation pads can be correspondingly operated according to the area requirement of the target area of a patient, the distance of the built-up effect on the surface of the skin is increased, the surface dosage of the patient is improved, and the compensation pad has the advantages particularly when large-area superficial skin tumors exist. The number of the marking holes 9 is large, so that more auxiliary marking points can be arranged for arrangement, and the problem of inaccurate repeated arrangement is solved. Due to the fact that the density of the PVC material is close to that of water, the PVC material can be used for planning radiotherapy, and the situation that the CT value is too high to make radiotherapy planning due to too high density is avoided.
If more compensation pads are needed, the expansion connection of more compensation pads can be continued through the front fixing plate 5 and the rear fixing plate 7. If the first compensation pad 1 or the second compensation pad 2 needs to be disassembled in the radiation process, the rubber sleeve can be taken down, and the front fixing plate 5 and the rear fixing plate 7 can be separated.
