Abstract

The invention relates to a titanium tantalum bone defect prosthesis and application thereof. The titanium tantalum bone defect prosthesis comprises tantalum metal in direct contact with bones and titanium metal integrally arranged with the tantalum metal, and the surface of the tantalum metal is of a porous structure. According to the titanium tantalum bone defect prosthesis, the titanium metal and the tantalum metal are used in combination, on the one hand, the titanium metal has good corrosion resistance ability, the special corrosion resistance ability of the titanium metal is enough to prolong the service life of the product and avoid corrosion and rusting of the product occurring inside a human body, on the other hand, the tantalum metal also has excellent corrosion resistance, does not react with liquid substances in the human body, and almost does not damage organic tissues of living things, therefore, the bone defect prosthesis made of the tantalum metal is sufficient to be combined with the organic tissues for a long time and stay harmless in the human body, thus the problem of poor bonding with the human body caused by only applying titanium is solved, and the problems that the cost of using only tantalum is higher and the heavy weight of the tantalum metal is not conducive to the rehabilitation of patients are solved.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to a titanium-tantalum bone defect prosthesis and its application. Background technique [0002] The incidence of osteoarthritis in my country is about 2.2% to 3.5%. According to statistics, the incidence of people aged 40 to 49 and 50 to 59 is about 27% and 62%. Total knee replacement is the best treatment for end-stage knee diseases. One of the effective methods can relieve pain, restore joint function, and improve the quality of life of patients. [0003] At the same time, the bone prosthesis in the prior art basically uses titanium or tantalum for printing. If only titanium is used, the binding force with human body defects may be insufficient due to insufficient affinity with the human body; if only tantalum is used, the Excessive weight is not conducive to the rehabilitation of patients, and the problem is that the price is too expensive. [0004] Furthermore, in the ...
