Description

Fluorine richness polyether-ether-ketone/graphite nanometer composite material, its preparation method and joint prosthesis Prosthese
Technical field
It is multiple in particular to a kind of fluorine richness polyether-ether-ketone/Nano graphite the present invention relates to artificial prosthesis Material Field Condensation material, its preparation method and artificial joint prosthesis.
Background technology
Since the sixties in last century, artificial joint replacement succeeded, the application of joint prosthesis is largely popularized, especially Be artificial, knee joint be countless patients solve motion problem.At present, artificial joint replacement has been considered as whole latter stage pass Save the effective treatment means of disease.It can not only release pain, improve range of motion and recover function of joint, prior It is to improve patients ' life quality.
Although the design and manufacture of joint prosthesis and clinical replacement operation level have increased significantly, lose in use The case of effect still constantly occurs.The classes such as the failure main forms of joint prosthesis are infection, dislocation, loosening, fracture, abrasion Type.Infection and dislocation mostly occur recent, and abrasion and bone dissolving are occurred in long term.Metal matches with ultra-high molecular weight polyethylene Joint prosthesis be the most frequently used combination at present, but polyethylene and bone dissolving caused by metal wear particles be failure at a specified future date most One of principal element.
Therefore, scholars constantly explore new combination, including:The application of high cross-linked polymer weight northylen, metal are to gold Category combination, ceramic-on-ceramic combination, ceramics have excellent friction and lubrication in vitro to polyethylene composition etc., these Combination novas Performance, but there is also respective shortcoming, and late result waits to observe.Metal-Metal interface, compared to metal to polyethylene interface Its coefficient of friction substantially reduces, and bone dissolution rate also decreases.But metal prostheses are worn release metal ions and particle, Potentially need further to be solved the problems such as the carcinogenic possibility of metal ion, metal allergy and renal toxicity, especially metal allergy May be closely related with Prothesis failure.Ceramics-ceramic interface, it is the minimum friction joint combination being currently known.Ceramics have pole High case hardness is advantageous to surface polishing, produces smaller surface roughness, can reduce friction.But ceramic-on-ceramic joint There is it is certain the shortcomings that, such as fragmentation of ceramic head and mortar cup, postoperative abnormal sound.
