On September 26, National Drug Administration approved the registration application for the innovative product of the "Proton Therapy System" produced by Shanghai Aipqiang Ion Equipment Co., Ltd. This product is a key support project for the "Digital Diagnosis and Treatment Equipment Special Project" key R&D plan of the Ministry of Science and Technology during the 13th Five-Year Plan period, and is also the first domestically produced proton therapy system approved for market launch in my country.
proton therapy is one of the most advanced tumor treatment methods in the world. It takes advantage of the advantages of protons in radio physical dose distribution and radiobiology. Patients do not need surgery during the treatment process. It has the advantages of accurate treatment, small side effects and high quality of life of patients. In addition to the indications of conventional radiotherapy, it is also particularly suitable for accurate treatment of children's tumors.
What is more worthy of attention is that more than 100 proton therapy centers have been built around the world, but most of them are distributed in developed countries such as Europe, America and Japan. my country's proton therapy devices rely on imports, and the construction costs and operation and maintenance costs are high, which not only leads to scarce treatment resources, but also leads to high treatment costs. The localization of proton devices is expected to significantly reduce equipment costs and medical costs, and provide many patients with malignant tumors with advanced treatment technologies and equipment with higher accessibility.
my country's "first domestically produced proton therapy demonstration device" was officially launched in 2012. It is jointly undertaken by Shanghai Lianhe Investment Company, Shanghai Institute of Applied Physics, Chinese Academy of Sciences (and Shanghai Institute of Research and Research), Shanghai Aipqiang Company and Ruijin Hospital . On November 30, 2021, my country's first domestically produced proton therapy demonstration device officially launched clinical trials at Ruijin Hospital Affiliated to Shanghai Jiaotong University School of Medicine.

Chen Jiayi, director of the Department of Radiotherapy of Shanghai Ruijin Hospital, said in an interview with Daily Xinhua Telecom on June 15, 2022 that the unique and superior physical properties of proton beams can greatly reduce the irradiation volume of normal tissues, thereby effectively reducing the side effects of radiation therapy. It also provides some tumors that cannot be cured due to the limitation of radiation tolerance of important normal tissues under photon therapy technology. It has irreplaceable advantages in the treatment of head and neck tumors, deep pelvic tumors, eye tumors and childhood tumors, especially helping to preserve the patient's quality of life. She described a 32-year-old young patient as an example, "The patient is almost blind due to skull base chordoma, with a wide range of lesions and adjacent to important tissue structures. While proton treatment eliminates tumors, it protects important tissues to the greatest extent. The patient has significantly improved vision and vision after only about 10 treatments."
