Description
Technical field
The present invention relates to a kind of prosthese of similar human body Bones and joints, specially a kind of novel hip prosthesis.
Background technique
Artificial hip joint replacing refers to similar with one kind made of the metal material of satisfactory mechanical property with biocompatibility
The prosthese of human body Bones and joints, the articular surface for being destroyed prosthetic replacement by disease or injury using operation method, purpose
It is removal of lesions, removes pain, restores the activity and original function in joint.Prosthetic replacement has joint motion preferable,
Can early stage Go to ground activity, reduce elderly patients' long-term bed complication the advantages that, in European and American developed countries, prosthetic replacement
Operation has been one of most common operation.China in recent years hip replacement development also very it is good rapidly.
Artificial hip joint product is generally made of four components；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, it is usually golden
Belong to material.With the universal component that upper-part is in common hip replacement, in the design of acetabular bone rollover repairing type hip joint components,
Usually there are four components, overhaul type acetabular cup, and acetabular bone voussoir, acetabular bone reinforcement block, acetabular bone gasket, material is usually metal material,
Including titanium alloy, tantalum metal etc..Manufacturing method is using metal powder rapid shaping, and product is complete opening gap, to facilitate Bone Ingrowth.
The benefit that does so reaches preferable long-term fixed it is clear that the product of complete opening gap can promote Bone Ingrowth.But it causes
A series of other shortcomings.First, the product be sterilization wrap medical instrument, the product of complete opening gap on cleaning and sterilizing very
Difficulty, because being accumulated when his production by metal powder.One typical metal voussoir is with a thickness of 10mm-30mm, to clear
It washes and brings very big challenge.Second, it can be seen that these products are used cooperatively with metal bone nail, then metal bone nail is piercing
When nail hole above these products, it can inevitably encounter or be extruded into hole wall, metal fragment may be generated, influence product uses the longevity
Life such as enters human body, may generate allergic reaction.Third, complete opening gap material are affected to the intensity of product.
