Abstract

The invention provides a preparation method of super-wear-resistant and high-toughness artificial hip joint with biological activity. The preparation method comprises six steps of preparation of a steel mold, preparation of an artificial hip joint germule, formation of a pore, filling of the pore with a PLLA / nHA compound, spraying of a PGA / nHA composite coating layer and surface degradation treatment. A composite material of polyether-ether-ketone and hydroxyapatite whiskers is used as a stent material; the pore is formed in a position corresponding to the stent material, and is filled with the degradable PLLA / nHA active composite material; then the PGA / nHA composite coating layer is sprayed; after the surface degradation treatment is performed, the super-wear-resistant and high-toughnessartificial hip joint with biological activity is obtained. The artificial hip joint prepared through the preparation method is combined with bones via the self-healing effect of bone induced cells onthe bones, and is higher in mechanical property, biological compatibility and bone combination strength than a conventional product.

Description

technical field [0001] The invention relates to an artificial hip joint, in particular to a preparation method of an artificial hip joint with super wear resistance, high toughness and biological activity, and belongs to the technical field of preparation technology of orthopedic surgery medical instruments. Background technique [0002] With the advent of an aging society, femoral head necrosis and femoral neck fractures in the elderly have become common diseases in orthopedics. It is the consensus of many scholars that hip replacement should be used as soon as possible for femoral neck fractures in the elderly. Hip replacement should pursue the least risk, quick recovery of hip joint function, and long-term joint pain-free plan. With total hip replacement, as long as the acetabular prosthesis and femoral prosthesis are fully matched, a more stable and pain-free joint can be obtained. Joints, and biologically fixed prostheses should be used as much as possible, so biomateri...
