Fully absorbed in 9 months after surgery, Shenzhen-developed magnesium-containing high molecular bone repair material approved for market.

On May 14th, the Medical Engineering Research and Development Center of the Advanced Technology Research Institute of the Chinese Academy of Sciences in Shenzhen, led by the teams of Qin Ling and Lai Yuxiao, announced that their "magnesium-containing degradable high molecular bone repair material", which has been researched and developed for 15 years, has been officially approved for market launch by the State Drug Administration's Innovation Medical Device Registration Approval for Class III Implantable Devices. This innovative achievement fills a gap in the industry, significantly improving the success rate of bone repair, effectively reducing patients' pain and complications, and playing a key role in promoting patient recovery and improving quality of life. It is understood that the transformation center has developed the "magnesium-containing degradable high molecular bone repair material" using low-temperature 3D printing technology, overcoming many technical difficulties in 3D printing orthopedic devices, successfully achieving precise shaping of magnesium-containing bone repair materials and giving the materials a special biomimetic structure and appropriate strength. At the same time, the material can be completely degraded and absorbed by the body within 6 to 9 months, avoiding foreign body reactions caused by material residue. The magnesium ions released during the degradation process can participate in the formation of new bone and normal physiological processes, accelerating the repair of bone defects.
