Description
Technical field
The present invention relates to a kind of similar osteoarticular prosthese of human body, a kind of novel hip prosthesis.
Background technology
Artificial hip joint replacing refers to biocompatibility similar with the one that the metal material of satisfactory mechanical property is made
The osteoarticular prosthese of human body, utilizes the articular surface that prosthetic replacement is destroyed by operation method by i or I, its purpose
It is removal of lesions, removes pain, recover movable and original function in joint.It is preferable that prosthetic replacement has joint motion,
Can in early days Go to ground activity, reduce the advantage such as complication of elderly patients' long-term bed, in European and American developed countries, prosthetic replacement
Operation has been one of modal operation.The development of China's hip replacement in recent years is also very good rapidly.
Artificial hip joint product is typically made up of four parts；Femoral stem, usually metal material；Femoral head, usually
Metal or ceramic material;Acetabular bone liner, usually ultra-high molecular weight polyethylene or ceramic material；Acetabular cup, usually gold
Belong to material.It is the universal component in common hip replacement with upper-part, repaiies in the design of type hip joint components in acetabular bone rollover,
Generally having four parts, overhaul type acetabular cup, acetabular bone voussoir, acetabular bone reinforcement block, acetabular bone pad, material is usually metal material,
Including titanium alloy, tantalum metal etc..Manufacture method is to utilize metal dust rapid shaping, and product is complete opening gap, to facilitate Bone Ingrowth.
The benefit of do so, it is clear that the product of complete opening gap can promote Bone Ingrowth, reaches the most long-term fixing.But cause
Other shortcomings a series of.First, this product is the medical apparatus and instruments of sterilization wrap, the product of complete opening gap on cleaning and sterilizing very
Difficulty, forms because piling up by metal dust during his production.One typical metal voussoir thickness is 10mm-30mm, gives clear
Wash and bring the biggest challenge.Second, it can be seen that these products be all with metal nail with the use of, then metal nail is piercing
During nail above these products, can encounter unavoidably or be extruded into hole wall, metal fragment may be produced, affecting the use longevity of product
Life, as entered human body, may produce anaphylaxis.3rd, complete opening gap material brings impact to the intensity of product.
