So, what's going on? I personally found relevant information, which is roughly as follows:
For some people with scar constitution, if you have an operation and remove the surgical suture, the scar on the knife edge is very obvious and very unsightly. With the advancement of medical science and technology, recently, the team of Academician Yu Shuhong of the Chinese University of Science and Technology was based on? Break off the relationship? Based on this phenomenon, a lotus-like bacterial cellulose hydrogel fiber for surgical suture was developed. Fiber suture has obvious advantages in protecting damaged tissue, promoting wound healing and reducing adverse reactions. Researchers processed bacterial cellulose (BC) hydrogel into hydrogel fiber (BHF) with lotus-like micro-helix structure, which has high strength and toughness, as well as excellent hydrophilicity and biocompatibility.
In addition, the bionic spiral structure endows the material with elasticity similar to human skin. When the wound is deformed, BHF can effectively buffer and absorb energy, realize synchronous deformation with human tissue, and avoid secondary injury caused by cutting the wound. Compared with traditional cotton thread or polymer thread, hydrogel fiber suture has the characteristics of high biocompatibility, high water content, low irritation and low friction resistance, and has obvious advantages in protecting damaged tissues, promoting wound healing and reducing adverse reactions, so it is expected to become the next generation of new high-end surgical suture.
Since 20 18, medical and surgical instruments in China have received frequent policy support, no matter what. Thirteenth Five-Year Plan? Planning outline, or? Made in China? Upgrade plan, etc. The innovative research and development and quality upgrade of domestic medical devices have been upgraded to an unprecedented height. However, the development foundation of China's medical device industry is weak, the industry supervision started late, and the phenomenon of small, multi-faceted, scattered and low-level competition among medical device enterprises has not been fundamentally changed. ?
Then, from the research and development of this new technology, the level of medical science and technology in China has made new breakthroughs and progress. In fact, compared with the medical level in China in 20 10, the medical system in China has been greatly improved. Most importantly, starting from the epidemic in 2020, the high-intensity scientific research achievement of the medical R&D team-COVID-19 vaccine-will be diagnosed in a short time.
In fact, there is still a gap between China's current medical level and large foreign medical institutions, but this gap has been gradually shortened. Most importantly, China's investment in medical care has increased, and the social security and welfare of medical staff have been improved, so that more medical staff can devote themselves to scientific research and medical care and contribute their own strength to the medical cause in China. I believe that in the near future, China's medical care will usher in more bright spots.
