On November 2nd GongBoHui held national conference and exhibition center in Shanghai, China's first independent research and development of proton therapy device is one of the core parts of 360 ° rotating frame, the spinning frame by the Shanghai city industrial co., LTD., Shanghai university of science and technology, Shanghai pudong development center of China aerospace science and industry group joint research and development, which will promote tumor treatment device - proton therapy device production comprehensive implementation of the localization.

Rotating frame localization success help reduce cancer treatment cost efficiency improve the cure of cancer
Although the proton therapy is known as the world's best "weapon" for cure, but not just China "the tumor edge tool" in the world are all in a state of extreme scarcity. At home, the key technology of high cost, lack of independent research and development of domestic is a major cause of its popularity difficult, localization of proton therapy device after rotating frame will help the proton therapy device for a smaller, more cost-effective and more and more cancer patients can benefit.
Proton heavy ion therapy, is what people usually call "proton knife" and "heavy ion knife", is to use a means of proton and heavy ion radiation to treat cancer, radiation therapy at the top of the current international technology. To kill cancer good effect and less side effects and has been hailed as a "weapon" for cure. Previously, only a few developed countries such as the United States, Germany and Japan at the same time to carry out the technology.
Remember on May 8, 2015, China's first with proton and heavy ion therapy technique at the same time when the opening of medical institutions - Shanghai proton heavy ion hospital big big dragon. The hospital clinical practice over the past year, the hospital treatment for nearly 300 patients. But in February this year the Shanghai center for disease control and prevention released the latest cancer affection monitoring data shows that on an average day in Shanghai with 162 new cases of malignant tumor. Proton hospital treatment efficiency is a drop in the bucket.
Open the proton heavy ion in Shanghai hospital website, home page pop up a latest statement: "the recent hospital found that criminals that have cooperation relationship with Shanghai proton heavy ion hospital by provides patients with consulting, registration, medical treatment, medical insurance and other services at the same time, charge patients is much higher than the actual cost of high registration, diagnosis and treatment hospital..." The indirect illustrates the proton heavy ion therapy in short supply, because the domestic treatment of queuing time is too long, many cancer patients can only go to Taiwan, Japan and so on has spinning frame, treatment of hospital is more efficient. Linkou chang gung memorial proton therapy center in Taiwan, for one, because its proton therapy device is equipped with a rotating frame, a day is the measure of the treatment of patients can approximately one hundred people, to enhance the efficiency of treatment is not only can benefit more cancer patients, but also reduce the patients' treatment costs, so Taiwan proton therapy is currently the world's most valuable.
The personage inside course of study points out, the proton heavy ion therapy equipment "standard" by "1 + 1 accelerator a rotating frame" gradually turned to "1 + accelerator 2 rotating frame" and gradually turned to "1 + 4 rotating accelerator frame", has its inevitable reasons: although in the absence of rotating frame facilities, proton therapy can still carry out, but for proton therapy center, to have a high quality of spinning frame, the number of patients can be treated the same time, about the number of patients treated without rotating frame under the condition of 10 times. As a result, the average cost of treatment can also greatly reduced.

Proton quality rotary rack device will meet construction boom market is promising
According to published data show that China has built, under construction in the proton heavy ion therapy center at nine. About 60 institutions at the same time, consciously or proton heavy ion therapy center is applying for construction, thus it can be seen, the proton heavy ion therapy center is expected to enter a new round of construction boom. But from clinical effect, the hospital investment and management, the localization of proton and heavy ion radiotherapy equipment research and development, as well as medical physical training ways and some need to discuss and solve the problem.
Proton heavy ion therapy to achieve conformal therapy, they need to effectively control the beam energy distribution of the horizontal position, vertical, in order to accurately match the shape of the lesion, this needs to be able to + 180 ° rotation, such as center location precision is very high (ideal precision error is less than 1 mm) of spinning frame, to realize the arbitrary Angle for beam. Especially in the field of heavy ions, at present only in Heidelberg, Germany ion treatment center (HIT) to use the high precision of heavy ion therapy with rotating frame, but buying domestic imports is faced with the huge costs and maintenance costs, so the domestic independent research and development is the best path to solve the high cost, the domestic other parts other than the rotating frame are relatively mature development. Celebration of the Shanghai industrial co., LTD., Shanghai university of science and technology, Shanghai pudong development center of China aerospace science and industry group independent research and development success and high precision, high stability, high ratio of the proton therapy device of 360 ° rotating frame, position accuracy has reached the < 1 mm, cracked the proton heavy ion beam is used for the accurate treatment of solid tumor core technology and engineering problems, provides for the construction of "healthy China" science and technology support.

According to the Shanghai celebrates the strong industrial co., LTD., chairman of HuaQingJiang is introduced, the technical team once for shenzhou 5 related parts technical support, the research and development is using its accumulated in many years in the field of space technology, developed a "high performance" 360 ° rotating frame.
HuaQingJiang said that celebrates the strong industry research and development of the proton therapy device 360 ° rotating frame to realize the current highest precision, precision than foreign "such as center" "using multiple bearing ring after columns to support the rotating frame to achieve rotation" 10 times more, "Angle positioning accuracy up to one hundred times, precision error is not more than 2 width of human hair; USES the unique "encircle all closed guide" free maintenance structure, no bare steel guideway, surface rust, don't have to maintain a high level of humidity, the whole therapy over the existing spinning frame on international technology, to do the double lower manufacturing costs and maintenance costs. Celebrates the strong industry research and development of the proton therapy device 360 ° rotating frame, will become the medical disruptive events, so to speak.
"There is currently no independent research and development of domestic successful 360 ° rotating frame, and the rotation of the existing successful application in the world frame both use and maintenance costs are high." To visit the medical equipment purchaser xu pointed out that the new arrival of 360 ° rotating frame will have great market prospect in the future. |
