Medical technology, refers to medical institutions and their medical personnel to diagnose and treat diseases for the purpose of making judgments and eliminating diseases, alleviating conditions, reducing pain, improving function, prolonging life, and helping patients to restore health and diagnostic and therapeutic measures. Medical technology is divided into three categories: The first category, medical technology refers to the safety and effectiveness of the exact, medical institutions through routine management in the clinical application to ensure its safety and effectiveness of technology. The second category, medical technology is the safety and effectiveness of the exact, involving certain ethical issues or higher risk, the health administrative departments should be controlled by the management of medical technology. The third category, medical technology is one of the following circumstances, the administrative departments of health need to strictly control the management of medical technology: 1, involving major ethical issues; 2, high risk; 3, safety and effectiveness need to be further verified by standardized clinical trial studies; 4, the need to use scarce resources; 5, the Ministry of Health regulations require special management of other medical technology. Annex III medical technology directory: 1, involving major ethical issues, safety, effectiveness needs to be further validated by standardized clinical trial studies of medical technology: cloning technology, autologous stem cell and immune cell therapy technology, gene therapy technology, central nervous system surgical detoxification, stereotactic surgery for psychiatric technology, allogeneic stem cell transplantation technology, tumor treatment technology, etc. 2, medical technology involving major ethical issues, safety and effectiveness of the exact: homologous organ transplantation technology, sex reassignment surgery, etc. 3, high risk, safety, effectiveness needs to be verified or safety, effectiveness of the exact medical technology: the use of particle generating devices and other large instruments and equipment to implement destructive treatment techniques, radioactive particle implantation therapy technology, tumor thermotherapy treatment technology, tumor cryotherapy technology, tissue, cell transplantation technology, artificial heart implantation technology, artificial intelligence-aided diagnosis and treatment technology. 4. Other medical technologies that require special management: gene chip diagnosis and treatment technology, broken bone augmentation surgery treatment technology, xenograft organ transplantation technology, etc.
