Abstract

The invention discloses a method for forming a high-anti-bacterial-performance titanium-alloy artificial hip joint. The method includes the following technological steps that (1) CT scanning and layered slicing processing of a patient hip joint data model are carried out; (2) titanium-copper alloy powder is designed and prepared; (3) laser 3D printing forming of a titanium-alloy artificial hip joint is carried out; (4), a titanium-alloy artificial hip joint with micro-nano-size porous structure surface is constructed in situ with the anodic oxidation technology; (5) the anti-bacterial performance of the titanium-alloy artificial hip joint is further improved with the plasma high-temperature nitridation technology; (6) cleaning, sterilizing and drying are carried out, and then packaging is carried out. According to the method, the complex structure and the high anti-bacterial function of the artificial hip joint are integrally manufactured in sufficient cooperation with the laser 3D printing technology, the surface modification technology and the excellent anti-bacterial performance of copper elements. The forming method is simple, outstanding in performance, suitable for personalized customization of the high-anti-bacterial-performance titanium-alloy artificial hip joint, and has good social benefits and economic benefits.

Description

technical field

[0001] The invention relates to a forming method of a highly antibacterial titanium alloy artificial hip joint, in particular to a forming method of a high antibacterial Ti-Cu artificial hip joint based on laser 3D printing, which belongs to the field of medical bone implant device manufacturing. Background technique

[0002] In recent years, due to the increasing aging of the global population and the increase in accidental injuries, the demand for artificial hip joints has surged. Titanium and its alloys are widely used as artificial joint materials due to their low elastic modulus, high specific strength, excellent corrosion resistance and biocompatibility, such as pure titanium and Ti6Al4V (TC4) for clinical use. At this stage, most of the artificial hip joint implants used in the domestic market are manufactured by a combined process of casting and machining. However, due to the complex macroscopic structure of the human hip joint and the low processing...
