Application of self-lubricating silicone in medical implants
The surface of some artificial joints will be coated with self-lubricating silicone. Taking the knee joint as an example, during the movement of the joint, self-lubricating silicone can reduce the friction between the joint surfaces and reduce the debris generated by wear. If there are too many of these debris, it may cause an inflammatory response in the body, and self-lubricating silicone can effectively extend the service life of the artificial joint and improve the patient's quality of life after surgery.
Some implantable drug sustained-release devices may use self-lubricating silicone in their shell or delivery part. This material can ensure the precise release of drugs in the body, while reducing friction between the device and surrounding tissues, and preventing problems such as device displacement.
