Abstract
The utility model relates to an artifical hip joint mortar cup, artifical hip joint mortar cup is concave type semicircle arcuation, including skin, inlayer, mortar cup inside lining and inside lining overcoat, wherein outer with a body structure is fixed into to the inlayer, inside lining overcoat parcel mortar cup inside lining, the outside of inside lining overcoat with inlayer surface closure, the inside lining overcoat inboard with mortar cup inside lining phase -match, the inside lining overcoat comprises the polyether ether ketone or derivatives thereof. The utility model provides an inlayer in the structure passes through the inside lining overcoat and the combination of mortar cup inside lining of polyether ether ketone (PEEK) or derivatives thereof, has reduced stress concentration, has also suitably increased the rigidity of mortar cup. The utility model discloses inside lining overcoat parcel mortar cup inside lining through PEEK or derivant in the structure combines with the inlayer again, can satisfy the matching requirement of hard inside lining, can satisfy the matching requirement of soft inside lining again.
Description
Technical field
This utility model relates to a kind of medical rehabilitation instrument, more specifically, relates to a kind of artificial hip joint mortar cup.
Background technology
Hip cotyle cup prosthesis of new generation generally adopts the design of lining more than a glass in recent years, and namely mortar cup can accept soft liner (UHMWPE liner) and hard liner (ceramic-lined or metal inner lining) simultaneously.But these two kinds of liners have distinct requirement to closing component structure, wherein soft liner requires outside sphere seamless contact mortar cup inwall as much as possible, thus eliminate water pump effect and ensure inner liner wall maximize thickness, hard liner then require the liner outer ledge conical surface and mortar cup conical surface of inboard wall sealed.
For different patients, the mortar cup being suitable for accepting soft liner had, the mortar cup being suitable for accepting hard liner had, but, for the mortar cup of hard liner, the particularly ceramic-lined distortion to mortar cup and the stress that formed is concentrated responsive especially of hard liner, in order to prevent the excessive mortar cup that causes of the stress of hard liner to mortar cup damaged, often maximizes the rigidity increasing mortar cup by the edge thickness of mortar cup.But such way is not only loaded down with trivial details, and often cause the more high a series of defect of cost of manufacture.
Therefore, the artificial hip joint mortar cup of the hard liner of a kind of acceptance newly expects.
Utility model content
For the technical problem of above-mentioned solution, the purpose of this utility model is to provide a kind of artificial hip joint mortar cup.
In order to realize above-mentioned utility model, this utility model adopts following technical scheme:
A kind of artificial hip joint mortar cup, described artificial hip joint mortar cup is inner concave shape semicircle arcuation, comprises skin, internal layer, mortar cup liner and liner overcoat, and wherein said skin and described internal layer are integrally fixed structure; Mortar cup liner described in described liner outer sheath covers, outside and the described internal layer surface of described liner overcoat are sealed, and inner side and the described mortar cup liner of described liner overcoat match; Described liner overcoat is made up of polyether-ether-ketone or derivatives thereof.
Further, described mortar cup liner is hard liner.
Further, described hard liner is ceramic-lined or metal inner lining.
Further, described internal layer surface is standard spherical structure, and described internal layer and described liner overcoat and described mortar cup liner form sliding friction surface.
Further, described internal layer surface is non-uniform spherical structure, and described internal layer and described liner overcoat and described mortar cup liner form assembly type fixed structure.
Owing to adopting above technical scheme, the beneficial effects of the utility model are:
1) internal layer in the structure that provides of this utility model, by the liner overcoat of polyether-ether-ketone (PEEK) or derivatives thereof and mortar cup interliner, reduces stress and concentrates, also suitably add the rigidity of mortar cup.
2) be combined with internal layer again by the liner outer sheath covers mortar cup liner of PEEK or derivant in this utility model structure, the coupling requirement of hard liner can be met, the coupling requirement of soft liner can be met again.

Detailed description of the invention
In order to make the purpose of this utility model, technical scheme and advantage clearly understand, below in conjunction with drawings and Examples, this utility model is described in further detail.Should be appreciated that specific embodiment described herein only in order to explain this utility model, and be not used in restriction this utility model.
As shown in Figure 1, an embodiment of the artificial hip joint mortar cup that this utility model provides, in this embodiment, artificial hip joint mortar cup is inner concave shape semicircle arcuation, comprise outer 1, internal layer 2, mortar cup liner 3 and liner overcoat 4, its ectomesoderm 1 and internal layer 2 are integrally fixed structure; Liner overcoat 4 wraps up mortar cup liner 3, the outside of liner overcoat 4 and internal layer 2 surface sealed, inner side and the mortar cup liner 3 of liner overcoat 4 match; Liner overcoat 4 is made up of polyether-ether-ketone (PEEK) or derivatives thereof.
In the above-described embodiments, mortar cup liner 3 is hard liner; Hard liner preferably ceramic liner.
In the above-described embodiments, internal layer 2 surface is non-uniform spherical structure, and internal layer 2 forms assembly type fixed structure with liner overcoat 4 and mortar cup liner 3.
In addition, the mortar cup liner 3 in the artificial hip joint mortar cup that provides of this utility model also can be the hard liner of metal inner lining; Internal layer 2 surface also can be standard ball shape structure, and internal layer 2 forms sliding friction surface with liner overcoat 4 and mortar cup liner 3.
Internal layer in the structure that this utility model provides, by the liner overcoat of polyether-ether-ketone (PEEK) or derivatives thereof and mortar cup interliner, reduces stress and concentrates, also suitably add the rigidity of mortar cup.
Be combined with internal layer again by the liner outer sheath covers mortar cup liner of PEEK or derivant in this utility model structure, the coupling requirement of hard liner can be met, the coupling requirement of soft liner can be met again.
The foregoing is only preferred embodiment of the present utility model, be not used for limiting practical range of the present utility model; If do not depart from spirit and scope of the present utility model, this utility model is modified or equivalent to replace, in the middle of the protection domain that all should be encompassed in this utility model claim.
