preparation example Construction

[0015] In the preparation method of the one-piece acetabular prosthesis of the present invention, the metal outer cup is first made by vacuum dewaxing casting or forging, and then the outer cup lining is constructed on the metal outer cup body by additive manufacturing technology.

[0016] The additive manufacturing technology is preferably but not limited to 3D printing.

[0017] The metal outer cup is preferably but not limited to be made by vacuum dewaxing casting or forging of a biocompatible metal material, wherein the biocompatible metal material is preferably but not limited to titanium alloy, cobalt-chromium alloy, wherein titanium alloy Including Ti-8Fe-8Ta-4Zr, compared with traditional titanium alloys, Ti-8Fe-8Ta-4Zr greatly reduces the elastic modulus, and can obtain excellent results in terms of mechanical properties and biocompatibility.

[0018] The outer cup lining is preferably but not limited to be made by 3D printing of biocompatible polymer materials, where...

Embodiment 1

[0020] A one-piece acetabular prosthesis, the preparation method of which comprises: using a titanium alloy material to manufacture a metal outer cup by forging, and then using an ultra-high molecular weight polyethylene material to directly construct the outer cup on the inner body of the outer cup by 3D printing lining.

Abstract

The invention discloses a preparation method of an integrated acetabular prosthesis. The preparation method of the integrated acetabular prosthesis comprising an outer metal cup and an outer cup lining comprises steps as follows: the outer metal cup is prepared with various machining methods, and the outer cup lining is formed on the outer metal cup with a material additive manufacturing technique. The integrated acetabular prosthesis is formed once, the outer metal cup and the outer cup lining are combined closely, micro-motions are reduced, accordingly, abrasion is reduced, machining procedures are reduced, and the cost is reduced.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to an orthopedic implant integrated acetabular prosthesis and a preparation method thereof. Background technique [0002] Artificial joint disease caused by disease and trauma is a common clinical disease and one of the worldwide problems in orthopedic treatment, seriously affecting the quality of life of patients. The metal outer cup and outer cup liner as the acetabular prosthesis is a relatively common orthopedic material in clinical application. The wide application of acetabular prosthesis in orthopedic treatment has significantly improved the problems that could not be solved clinically in the past, and the success rate of implantation has also reached quite satisfactory results. At present, the metal outer cup and the outer cup lining are independently processed and packaged, and the cooperation between the two needs to be performed through surgical operations. Wear...
