Abstract
The invention discloses a biological type artificial joint prosthesis. The biological type artificial joint prosthesis comprises a surface porous structure and an internal three-dimensional porous bone tissue engineering supporting structure. The surface porous structure is communicated with the internal three-dimensional porous bone tissue engineering supporting structure. According to the biological type artificial joint prosthesis, the bone tissue engineering technology is applied to the artificial joint prosthesis, and the artificial joint prosthesis and bone tissues can grow into a whole; because the structure between the artificial joint prosthesis and a bone interface is successive, functions and stress transfer of the artificial joint prosthesis are successive, the interface bonding strength can reach or even exceed the strength of the artificial joint prosthesis and the strength of a bone; consequently, the biological type artificial joint prosthesis can effectively shorten the reinforcing and fixing time to obtain permanent stability and can obviously reduce complications caused by prosthetic loosening and sinking, so the service life of the artificial joint can be prolonged.
