Detailed Description

The invention will be further illustrated with reference to the following specific examples. It should be understood that these examples are for illustrative purposes only and are not intended to limit the scope of the present invention. Further, it should be understood that various changes or modifications of the present invention may be made by those skilled in the art after reading the teaching of the present invention, and these equivalents also fall within the scope of the present application.

Breast cancer is one of common malignant tumors of women, the incidence rate of the breast cancer is increased year by year, and the reasons are complex and comprise multiple aspects of heredity, hormone, reproduction, nutrition, environment and the like. In terms of treatment means, general surgery, radiotherapy and chemotherapy are three effective measures, and can be used singly or in cooperation with each other. Because of the effects of the radiotherapy on tumor inhibition, metastatic infection resistance, shrinkage and the like, the whole milk can be treated by adopting the radiotherapy alone, or combining the radiotherapy after chemotherapy, or adopting a radiotherapy method before operation for cases which do not meet operation conditions, have larger tumor range and great operation difficulty, want to preserve organs, transfer in milk and the like.

In one aspect, in the fixation of the positioning of the treatment. In radiotherapy, in the current clinical operation, a patient needs to lie on a treatment bed, and due to the flexibility of a human breast, the state and the positioning of the breast are inconsistent after lying down each time, so that the consistency and the accuracy of a target position of a radiotherapy target cannot be ensured. Therefore, in order to fully expose and correspond accurately, before the first radiotherapy, a mammary gland fixing sheet is required to be manufactured, and the mammary gland fixing sheet is mainly used for ensuring that the mammary gland of a patient can be fixed to a constant state during each treatment.

The operation mode of current hospital is, lets the patient lie flat, puts in the front with soft blanket, relies on the soft characteristic of blanket self to combine gravity, and the curve of natural laminating front side then swabbing stoving design. The fixing sheet manufactured by the method has an unsatisfactory fitting effect on a human body curve. The fixing effect on the chest is also poor.

On the other hand, since the first-line clinical period, there are too many patients who have complications such as radiation pneumonitis, osteoporosis, rib fracture, skin disease, etc. due to radiation therapy of breast cancer or other breast malignant tumors, and although breast cancer in situ is not fatal, there are few patients who have complications of other diseases due to the course of treatment. Patients often have poor physical burden capacity, and the problem that people repeatedly think for many years in treatment is how to prevent diseases while treating diseases through radiotherapy. First, in such a lying posture, the irradiation range is concentrated on the skin and organs around the chest, which is unavoidable. We repeatedly studied the treatment process and proposed an innovation in lateral irradiation treatment, but this method has a higher demand for the fixation sheet because the patient stands up on his upper half or lies on his side in the lateral irradiation condition. The breast, regardless of size, hangs down on the front side according to gravity. If the affected part is squeezed, the effect of the radiation therapy is affected. And is close to the front side of the body, and the far-away effect on other organs is also reduced. Therefore, the fixing sheet is required to have good fixation on the breast, and also be capable of extending the breast tissue forward as much as possible to enable the breast to stretch forward.

In order to solve the problems, a breast traction fixing device is designed, and the device also independently applies for the national invention patent. Mainly be bilayer structure, the casing cover piece of outer stereoplasm, the interior flexible silica gel lining piece of inlayer through wearing earlier to the lining piece, lets the lining attached on the skin before the chest, and the rethread is pull the piece and is gone up lining piece location fit to the assigned position of cover piece to realize fine drawing god to the breast and pull, let the breast reset to keeping away from the chest that bows of health and draw god state of expansion. The traction effect is very good, and the traction is like other existing protective covers, and the traction is required to be manufactured independently according to patients, and the patient can carry the traction after the traction is finished, and the patient can carry the traction every time the patient is treated. In the manufacturing process, the most important link is the acquisition of three-dimensional data of a patient.

In the acquisition of three-dimensional data, a three-dimensional curved surface of a patient breast in a forward natural extension state is mainly acquired. For example, in the prone position, the chest naturally droops under the action of natural gravity. The three-dimensional curved surface in the state not only can enable the breast tissue to be far away from the surface of the chest, but also can be naturally achieved, and the patient can not feel obvious discomfort caused by pulling and traction. It is best to assume the prone position of the chest.

The existing means is to take the mold on the back, and mainly solves the technical problem that the mold turning in the prone position cannot be overcome by customers. In the case where a person has his chest vertically drooping downward, it is equivalent to taking a sample on a curved surface below. Except for adopting a three-dimensional scanning technology, the existing other measures cannot be realized.

However, the three-dimensional equipment and the method are very expensive in use, the equipment price is high, and the cost of matched software and printing materials is high. For example, software and suppliers are charged according to the piece number, the software and the suppliers can be used all the time without purchasing, the chest area is large, materials are wasted, printing materials are expensive, the lower surface of a printed model in the prior art cannot be smooth, and further polishing is needed. And the use of equipment software and the processing of printed products require the manufacturer to operate with a stationing professional. Thus, a set of cover and liner sheets is produced, the cost of equipment + software + materials + labor is very high, more expensive than the treatment itself, and is unbearable for the patient.

In order to enable the method and the device to be widely popularized, a device capable of overturning a mold is designed aiming at barrier points in manufacturing of an outer cover and an inner liner, namely the acquisition of a three-dimensional curved surface of a patient under the condition that the chest is naturally far away from extension, namely the technology applied by the invention, so that the acquisition and shaping of the chest prone three-dimensional curved surface are realized, and the technology can fall to the ground.

Embodiment 3 a prone position chest rollover device

Unlike example 1, in this example, the inflatable body we designed is of an arc-shaped configuration, and in terms of the design of the inflatable body, we prefer to use the air bag because of the abundant inert gas resources in hospitals. More flexible, and better control of the degree of expansion and degree of compression.

In embodiment 1, the expansion ring of the annular air bag structure is restrained by a detachable manner and a hard limiting part which is relatively closed to form an annular part, although the expansion ring is slightly complicated when being worn, the expansion ring has better effects on flow resistance and leakage prevention of gypsum. Meanwhile, each component is convenient to disassemble quickly. The locating part card is gone up in the expansion ring, and the two insert in semi-circular or semi-elliptical recess together, crowd the locating part through the recess, and the expansion ring is crowded to the locating part, lets the expansion ring crowd human neck, upper arm, belly can. The quick release and quick assembly can be disassembled into small components, and the small components are convenient to clean and disinfect. This is important because in practice, the patient may be inaudible to manufacture, so that the rapid disassembly structure of embodiment 1 can be used to sample the next patient by merely replacing the expansion ring and the stop member. The expansion ring and the limiting part are cleaned in a centralized way after the paragraph, and each component is convenient to replace independently, so that standardized components are easy to form for trial use. But also can set up the expansion loop into the different internal diameters size of inflation back, to the comparatively obvious patient of fat thin, can directly use the expansion loop of appropriate internal diameter just can realize the adaptation to different sizes through changing.

But we have also devised a structure of this example as well. Mainly for the expansion ring is the arc of undercut, fixes in the recess, specifically is:

the box body 3 is detachably fixed in the mounting window.

A neck expansion pad is fixedly arranged in the neck groove 8; the curved surface of the top side of the expanded neck expansion cushion is an arc shape which is adapted to the physiological curve of the neck,

an upper limb expansion pad is fixedly arranged in the upper limb groove 11; the curved surface of the top side of the expanded upper limb expansion pad is in an arc shape which is adaptive to the physiological curve of the upper limb,

an abdomen expansion pad is fixedly arranged in the abdomen groove 14; the top side curved surface of the expanded abdominal expansion pad is in an arc shape which is adaptive to the physiological curve of the abdomen.

Neck inflation pad, upper limbs inflation pad, belly inflation are all equipped with the air cock on filling up, through aerifing the inflation and be an air cushion that the top side has the arc sunken, play the effect that keeps apart and prevent to spill the gypsum fluid.

The expansion body of this example cannot be disassembled, and has the advantage of being quick and convenient to use. When the patient uses the pillow, the patient can directly climb on the stomach at a proper position, namely the neck is respectively placed in the neck expansion pad, the upper arm is stretched in the upper limb expansion pad, and the medical plaster can be poured when the abdomen naturally falls in the abdomen expansion pad. It is very fast and simple.

However, after one patient finishes, the whole box body 3 is taken down, and the new box body 3 is replaced, so that the patient can use the expansion body for the next patient, and meanwhile, the expansion body is a vulnerable component and is not beneficial to replacement. However, the use efficiency is certainly greatly improved, and it is still necessary to a patient who is not physically flexible.
