What is the experience of hanging up 45 tons of "Giant Mac" equipment and "close -fitting" from the small door of the roof? At 9:45 on September 8th, at the Jinyin Lake Hospital of Xiehe Hospital Affiliated to Huazhong University of Science and Technology, the world's third set and the first Probeam360 ° proton radiation therapy system in the Asia -Pacific region began installation. The core component of the 45 -ton weight -360 ° rotating racks slowly rose, and the 40 -meter height was accurately hung into the ground -based pits on the first floor of the underground, which is parallel to the base. This marks the Hubei Province and even central China. Tumor diagnosis and treatment opened a new chapter.

The air rotor rehearse for 2 hours

At 9.45 am, with a order, a 10 -storey crane starting was started, and the rotary rack was slowly lifted. After the 40 -meter high -air conditioning angle and position, aimed at the reserved roof reserved on the roof. "Temporary entrance" has dropped steadily. For 30 minutes, everyone's attention was focused on it.

It is understood that this is the core component of the proton -360 ° rotating rack. How big is it? The equipment gives numbers: it is 7.8 meters long, 3.6 meters wide, 3.4 meters high, and weighs 45 tons. It integrates electrical cabinets, imaging boards and other equipment, and will "partners" with superconducting rotary accelerators in the future to provide treatment for cancer patients.

Jimu reporters learned that this big guy was "born" in Germany. After arriving in Shanghai Port, he "took" the truck to Wuhan after nearly 3 months. During the period, it finally arrived at Xiehe Hospital after a strict quarantine.

"This is the world's third set and the first set of PROBEAM360 ° proton radiation therapy system in the Asia -Pacific region. The difficulty of hanging is self -evident. The team prepared for three months before and after." Xie Rui, the project management manager of Varian Asia Pacific The domestic and foreign expert teams have surveyed several times at the scene, and accurately measured and calculated to design the most suitable lifting solution.

"Hanging such a big guy, not chopsticks, and then putting it in the plate so simple." Xie Rui introduced that the maximum lifting torque of the selected crawler crane is more than 500 tons/meter. Weighing blocks, repeated simulation rehearsal. The changes in wind speed and wind direction that day will affect the stability of the rotary rack in the air. To this end, the four staff members of the scene were drawn with the traction rope at the time of hanging to ensure that the "big guy" would not shake at the high altitude. At the same time, the ground staff and the crane driver speak through the VIP line to ensure that they are not disturbed by external signals. Details are connected in real time. At the same time, the top of the crane is also equipped with a camera to ensure that the driver can see the ground condition.

Xie Rui introduced that in order to cooperate with the perspective of the foundation of the foundation pit, this big guy has a "turntable" action in the air, which needs to be tilted 90 degrees to decline in parallel with the base reserved in the foundation pit. At this perspective, we spent more than 2 hours when we preview to ensure that everything is everywhere. "Xie Rui lamented, not only that, in order not to affect the construction of the building, the team took a different approach and reserved the" entrance "on the roof to allow the giant equipment equipment to device. Complete the installation, so the construction and installation are not wrong.

The pile foundation enters the underground 58 meters deep

The proton therapy system is currently the most advanced radiation therapy. It is popular as a "proton knife", and proton therapy can be called the "ceiling" in the radiotherapy industry. As one of the first batch in the country and the only proton radiation therapy system issued by the National Health and Health Commission, Wuhan Union Hospital has customized the first Probeam 360 ° proton therapy system in Varian Medical Asia Pacific in 2020. At the same time, it is equipped with Warian Probeam360 ° multi -room scalability system, ARIA tumor information management system, Eclipse radiation therapy plan system and Halcyon smart radiotherapy platform.

In order to settle this system, Xiehe Hospital has specially built a proton medical center, located next to the Jinyin Lake Hospital of the hospital, and was undertaken by the China Construction Three Company. The center covers an area of ​​about 50 acres, and it is planned to invest 700 million yuan in the first phase, with a construction area of ​​25,500 square meters. It is planned to set up 4 treatment warehouses and laboratories. Wang Zeyu, deputy secretary of the party committee and general manager of Zhongnan Company, China Construction Third Bureau, introduced that although the construction area of ​​the proton area is only 3200 square meters, its complexity is large, and the difficulty of construction is rare in the engineering field. You can learn from it. There are very few experience, and the project construction team is built while groping.

How difficult is it to build a proton center? Kou Wenyuan, the project manager, introduced that the team must achieve "zero sinking", "zero vibration of buildings", "zero cracks in the wall", "zero blockage of embedded pipelines", "reserved embedded zero deviations", "ultra -thick and overweight concrete concrete" "".

Kou Wenyuan explained that in order to achieve a "zero settlement", the team brought a pile foundation of 1 meter into the underground 58 meters deep. The foundation of the proton area can withstand up to 200 meters of ultra -high buildings, which also means that the proton medical center area is in the area. The settlement within 10 years is less than 0.2 mm to prevent the device from shifting. In addition, the proton zone cannot have a slightest shock with the surrounding environment, and the construction of the building is 4.5 meters thick, and even a strong earthquake will not suffer much.

In order to solve the problem of the "escape" of the proton, the wall of the proton zone treatment warehouse cannot be greater than 0.2 mm, that is, the penetrating cracks of the hair wire. The construction team mixes more than 10 metal elements such as iron, hydrogen, and boron in ordinary concrete, and its density is 3.9 tons per cubic meter. In addition, the total length of various curved pipelines is 20,000 meters. "This is a project that cannot be rewarded. Once a pipeline is missed, it means that the system is not closed and cannot be used." Kou Wenyuan introduced.

1500 patients can serve each year

What can the proton medical center do after completion?

Proton treatment renderings

Professor Zhang Tao, Secretary of the Party Committee of the Cancer Center of Wuhan Union Hospital, introduced that compared with traditional photon radiation therapy methods, the proton is unique to the Prague peak dosage distribution curve and is known as the "dragon knife" in the radiotherapy industry. In popular terms, the "proton knife" of Xiehe can accelerate the proton beam to 160,000 kilometers per second. Before arriving in the tumor lesion, the energy was released by less than 25%. When the lesion was reached With no dead corners, "fixed -point blasting" of the tumor site, at the same time, minimize damage to the surrounding health tissues and organs, and the treatment accuracy can be controlled within 1 mm.

Professor Zhang Tao said that proton therapy is expected to provide more advanced treatment methods for liver cancer, lung cancer, central nervous system cancer, skull cancer, head -neck cancer, esophageal cancer, breast cancer, prostate cancer, child cancer, and recurrent cancer patients with more advanced treatment methods Essence

"Painlessness and no sense of treatment during the treatment process, especially suitable for children with cancer patients." Professor Zhang Tao explained that because children are still developing, important organizational organs are more closely arranged, reducing the radiation of children's health tissues and organs, and it will reduce Long -term side effects are conducive to reducing the recurrence of secondary tumors.

It is worth looking forward to that the system can also upgrade the third -generation proton therapy technology -FLASH treatment technology. Flash treatment increases the current clinical proton treatment intensity of 72 times, and the treatment efficiency can be increased by 16-30 times compared to existing proton therapy. A course of treatment is reduced from 20-30 times to 1-3 times. By 1 second.

Hu Yu, president of Wuhan Union Hospital, said that after the futures proton center is put into use, it will quickly drive and enhance the level of tumor diagnosis and treatment in Hubei Province and even central my country, fill the gaps of proton treatment in the area, and serve more than 1,500 cancer patients each year.
