(11) acetabular cup 1 and the threedimensional model of the trabecular bone structure 3 are carried out by slicing treatment using Slice Software
Form section file；
The acetabular cup 1 and the threedimensional model of the trabecular bone structure 3 can so make：By the three-dimensional mould of acetabular cup 1
The file that type changes into STL forms preserves, and by software processing, outer surface 11 is processed into trabecular bone structure 3, will be with hip
The inner surface 12 that mortar liner 2 contacts is processed into the rough surface with microcellular structure, it is of course also possible to use other method systems
Make；
(12) the section file is imported in the 3D laser printing apparatus.
The Slice Software can be any suitable Slice Software, for example, 3D laser printing apparatus carry software or
Magics softwares.The minimum thickness of the individual layer obtained of cutting into slices should adapt to the requirement of 3D laser printing apparatus, for example, 30 μm, 50 μm,
60 μm can be with, can specifically be determined according to unit type requirement.
The 3D laser printing apparatus can be any suitable 3D laser printing apparatus, such as Germany EOS M290, moral
State SLM 500, U.S. 3D Systems LayerWise, etc..
The material powder is exactly the powder for the material that the acetabular cup 1 and the trabecular bone structure 3 use, the acetabular bone
Cup 1 and the trabecular bone structure 3 may be employed any suitable material and formed, described in the specific embodiment of the present invention
Material powder is metal powder.The metal powder can be such as titanium alloy powder.
Therefore, the present invention provides the integral acetabular component of a kind of glass of lining, the wherein rough surface of trabecular bone structure can be with trouble
The cancellous bone of person's acetabular bone effectively combines, and improves early postoperation fixed effect, and higher porosity, suitable pore size stimulate
Bone tissue ingrowth into realizing steady in a long-term；Acetabular cup inner surface is microcellular structure, can be by way of " welding " and acetabular bone
Liner is fixed together, and has not only remained the original intensity of acetabular bone liner, but also eliminates acetabular bone liner and acetabular cup in surgical procedure
Installation steps, while substantially eliminate abrasion caused by the loosening between acetabular cup and acetabular bone liner, improve artificial and close
Save the service life of prosthese.
To sum up, the firm stabilization of the integral acetabular component structure of cup lining of the invention, can improve early postoperation fixed effect and
Steadily in the long term, safe to use simple and convenient, service life is long, ingenious in design, simple for structure, and manufacture is easy.
It can be seen that the purpose of the present invention is achieved completely and effectively.The function and structural principle of the present invention
It is shown and is illustrated in embodiment, under without departing substantially from the principle, embodiment can make arbitrary modification.So this hair
The bright all variant embodiments included based on claim spirit and right.
