Abstract
The utility model discloses an improved acetabulum plastic component of artificial hip joint which is characterized in that the utility model is based on the characteristics of the human body. A cup mouth of a fundamental cup body of a plastic component is provided with a dislocation-preventing edge which is higher than the section of the cup mouth in order to avoid the dislocation. The design enhances the service life of the product and eliminates the physiological burden of patients. The utility model is applicable to the hip bone replacement surgery for the hip joint disease.
Description
Affiliated technical field
This utility model relates to the artificial joint of medical domain.Particularly a kind of improved artificial hip joint acetabular bone plastic components.
Background technology
Artificial hip joint acetabular bone plastic components is a body implant.The alternative of implant into body hip joint when being used for the human hip pathological changes and need carrying out the orthopaedics replacement operation can be fixed in the outer cup of metal acetabular bone metal or directly uses bone cement to be fixed on the osseous tissue.Make patient recover the physiological function of hip joint to a certain extent, alleviating pain improves motion and improves the quality of living.In prior art, the unpolarized dearticulation-proof high edge of rim of a cup of plastic components basis cup does not form the anti-dislocation of protectiveness to the little bulb in the plastic components, does not meet the requirement of human biology, in use may cause the bead head dislocation in the plastic components.Increase the mortality of replacement, increased the weight of patient's physiological load.
Summary of the invention
The purpose of this utility model is to provide a kind of improved artificial hip joint acetabular bone plastic components, can overcome existing artificial hip joint acetabular bone plastic components and the back is installed because of installing bad or muscle strength is not enough or improper use has the defective of dislocation in use the time.
Task of the present utility model realizes by this way: this artificial hip joint acetabular bone plastic components is characterized in that making the dearticulation-proof high edge that is higher than the rim of a cup cross section at the rim of a cup of plastic components basis cup.
From above-mentioned improvement as can be known, owing on the rim of a cup of plastic components basis cup, made dearticulation-proof high edge,, can prevent the dislocation of bead head according to the characteristics of body biomechanics.
When implementing this utility model, the height that described dearticulation-proof high edge exceeds cup rim of a cup cross section, plastic components basis is 0.5～30 millimeter.Highly excessive, cause interchangeable bulb to be difficult for packing into, influence mobility simultaneously; Highly too small, do not reach the effect of the anti-dislocation of bead head.
Description of drawings
Figure: be the sketch map of a kind of concrete structure of this utility model
The specific embodiment
As shown in the figure, this utility model of being made up of plastic components basis cup 1 and dearticulation-proof high edge 2 disjunctors and its installation of existing artificial hip joint acetabular bone plastic components, specification are basic identical.Its difference is to make the dearticulation-proof high edge 2 in high cup mouth cross section at rim of a cup 3 disjunctors of plastic components basis cup 1.The height that dearticulation-proof high edge 2 exceeds cup 1 rim of a cup cross section, plastic components basis is 8 millimeters.This artificial hip joint acetabular bone plastic components can adopt medical superhigh molecular weight polyethylene material mold pressing disjunctor to make, and also can adopt the machining process disjunctor to make.
Claims (2)
1, a kind of artificial hip joint acetabular bone plastic components, include the artificial hip joint acetabular bone plastic components that the basic cup (1) of plastic components and dearticulation-proof high edge (2) disjunctor are formed, it is characterized in that going up disjunctor at the rim of a cup (3) of the basic cup (1) of plastic components makes the anti-dislocation edge in the cross section that is higher than (3).
2, artificial hip joint plastics acetabular bone parts according to claim 1 is characterized in that the height that dearticulation-proof high edge (2) is higher than the cross section of (3) is 0.5～30 millimeter.
