The method prepares a metal transfer printing template with a surface lug boss array by using part of a process of UV-LIGA, and uses the template to press a surface texture with a pit array on the surface of the ultrahigh molecular weight polyethylene so as to improve the tribological performance of the ultrahigh molecular weight polyethylene serving as an artificial joint material.
Description
Technical field
The present invention relates to a kind of joint prosthesis with superhigh molecular weight polyethylene material surface superfine texture working method, belong to the bio-tribology field.
Background technology
Ultrahigh molecular weight polyethylene(UHMWPE) (UHMWPE) has superior biocompatibility, high chemicalstability, bears bigger characteristics such as shock load; So designed first since John Charnley in 1963 since the hip prosthesis of stainless steel femoral head and the combination of ultrahigh molecular weight polyethylene(UHMWPE) acetabular bone of diameter 22.5mm, ultrahigh molecular weight polyethylene(UHMWPE) is applied among the prosthetic replacement widely.
Surface texture (Surface texture) promptly processes the pit with certain size and arrangement or the dot matrix of small groove on surface of friction pair, put into practice being proved to be, and such small groove dot matrix is a kind of effective means of improving the surface friction characteristic.
Ultrahigh molecular weight polyethylene(UHMWPE) has become present most widely used artificial articular cartilage material; But along with the replacement joint growth of working life; Ultrahigh molecular weight polyethylene(UHMWPE) and pottery or metal are joined pair friction for a long time in vivo, still have the problem of many frictions, wearing and tearing aspect.At first with respect to natural live body joint, the frictional coefficient of ultrahigh molecular weight polyethylene(UHMWPE) is bigger, far above the range of friction coefficients in natural live body joint 0.005～0.002.Secondly, the ultrahigh molecular weight polyethylene(UHMWPE) abrasive dust that is produced by wearing and tearing can cause Periprosthetic osteolysis and aseptic loosening.
Existing research shows, the cylinder shape pit array that adopts CNC milling machine to go out to have certain depth in the UHMWPE surface working can effectively reduce UHMWPE surface and frictional coefficient and wear rate to the mill steel ball.UHMWPE is carried out N+, O+, C+ plasma injection modification, and carbon fibre filling etc. can obviously improve the said material surface hardness, improve its abrasion resistance.But it is its antifriction performance is improved not quite, even bigger than there not being ion implantation ultrahigh molecular weight polyethylene(UHMWPE) frictional coefficient.Adopt methods such as gamma-rays radiation, change wellability in addition in addition.
The content of invention
The object of the invention is to provide a kind of surperficial superfine texture working method that can improve superhigh molecular weight polyethylene material surface friction performance.
A kind of joint prosthesis is characterized in that comprising following process with superhigh molecular weight polyethylene material surface superfine texture working method:
Step 1: tinsel is through surface finish, as matrix;
Step 2: the metal material surface after step 1 evenly applies photoresist material;
Step 3: the test specimen to after the step 2 toasts;
Step 4: utilize mask plate, the test specimen of step 3 is made public;
Step 5: the development rinsing obtains having the sheet metal of photo etched mask;
Step 6: with the metal salt solution is electroplate liquid, and the sheet metal through the development rinsing in the step 5 is carried out little electroforming, obtains the microcylinder of preset height in foil surfaces, processes the transfer printing template; Metallic element is identical with basic metallic element in the wherein said metal-salt;
Step 7: with the mould of packing into simultaneously of resulting transfer printing template and powdery ultrahigh molecular weight polyethylene(UHMWPE) in the step 6, the ultrahigh molecular weight polyethylene(UHMWPE) test specimen that obtains having surperficial texture through presuppression, high temperature sintering, compression moulding and releasing process.
The present invention is through the part technology of UV-LIGA; Preparation has the metal transfer printing template of surperficial boss array; Utilize this template to make surperficial texture, thereby improve its tribological property as artificial joint material with pit array in the ultrahigh molecular weight polyethylene(UHMWPE) surface pressure.
