Abstract

The invention relates to a preparation method of a polyether-ether-ketone (PEEK) composite material artificial joint, belonging to the technical field of medical materials. In order to solve the problems that the existing composite artificial joint materials are still worn and subjected to fiber breakage under the complicated physiological conditions and stress states and even have the possibilityof breakage, and the particles generated by abrasion also cause the inflammatory reaction of local tissues, the invention provides a preparation method of the PEEK composite material artificial joint. The artificial joint manufactured by using the technical scheme provided by the invention has the advantages of being good in biocompatibility and wear resistance, and the like.

Description

technical field [0001] The invention relates to a preparation method of a PEEK composite material artificial joint, belonging to the technical field of medical materials. Background technique [0002] Artificial joints are implantable prostheses made of artificial materials to replace damaged or diseased joints in order to treat fractures, joint deformities, joint ankylosis and various destructive bone and joint diseases. Artificial joint replacement is an effective method to treat advanced osteoarthritis, eliminate joint pain and improve function. Together with fracture internal fixation surgery, it is hailed as a great breakthrough in the field of orthopedics in the 20th century. It enables these diseased joints to be corrected and restored. Normal function helps improve the quality of life of some rheumatoid arthritis and osteoarthritis patients whose joints are severely damaged. [0003] Medical practice has shown that the performance of artificial joint materials and t...
