China News Service, November 4, according to South American Overseas Chinese News reported on the 3rd, recently, an artificial bone screw invented by Panamanian scientists was approved for commercial use by the US Food and Drug Administration.
This product can not only degrade, but also help patients fight inflammation and bacteria.
According to reports, a laboratory led by Panamanian scientist Amel, who graduated from the University of Panama and currently teaches at the Department of Biomedical Engineering at Northwestern University, invented a medical device for orthopedic surgery.
The device can promote the regeneration of human tissues and disappear from the patient's body over time.
According to the report, this artificial bone screw is called "Citregen". It uses a ceramic material that can be gradually degraded and absorbed under the action of a physiological environment. The material is a citrate-based polymer antioxidant with a composition structure. Very close to human bones.
Amel introduced that once it is surgically implanted into the opening of the bone and the ligament or tendon is fixed to the bone, the artificial bone will gradually dissolve and release citric acid, which is very important for the metabolism of cells and adjacent tissues.
Citric acid not only has anti-inflammatory and antibacterial effects, but also promotes cells to become bone cells, accelerating the regeneration process of bones and the connection between tendons and joints, and ligaments and bones.
"In the end, the artificial bone screw will disappear completely, the ceramic materials and minerals will be metabolized and integrated into the newly formed bone, and the area where the device was originally implanted will start the regeneration process of the original tissue," Amel explained.
According to reports, the previous artificial bone screws not only take 3 to 5 years to be degraded, but also cause a lot of chronic inflammation in the patient's body.
