Abstract
The utility model relates to an outer cotyle lining of an artificial hip joint, which includes a lining body and driftbolts integrally formed with the lining body; a three-dimensional net body is integrally formed with the outer surface of the lining body, the surface of the three-dimensional net body is provided with a plurality of blind holes, the inside of the three-dimensional net body is provided with transverse ducts of the holes from the outside to the inside on the communicating part or of all the holes, the driftbolts are formed by the lining body stretching outwards and are parallel to the axis of the lining body; the amount of the driftbolts can be one or more. After the patient is provided with the outer cotyle lining of the artificial hip joint, the osteocytes can be embedded into and grow into the meshes of the three-dimensional net body and surround and close the meshes, so that the looseness between the outer cotyle lining of the artificial hip joint and the sclerotin can be effectively and permanently prevented.
Description
Technical field
This utility model relates to a kind of artificial hip joint acetabulum outside liner.
Background technology
Artificial hip joint replacing operation has at present become a kind of common relatively surgical operation in medical circle, remains an everyway in the continuous problem of exploration but how to remain on stable in the acetabular bone chamber as the implant acetabulum outside liner of acetabular bone side.Progress along with industrial technology in recent years constantly has novel acetabulum outside liner to occur, for example at acetabulum outside liner surface pyrolytic coating alloy powder, the pyrolytic coating biological ceramic powder, the sintering metal microballon, machining goes out groove, concavo-convex rough surface, be screwed or the like, its main purpose is exactly to increase the contact area of acetabulum outside liner and sclerotin and frictional force to delay the generation that implant is become flexible, but groove that forms by said method and rough surface etc. all are Embedded, because the caused molten ossein of chip that the articular surface long term wear comes off causes the atrophy of osteocyte degeneration still inevitable, therefore the loosening acetabulum outside liner that still might cause of the disengaging in gap, interface is implanted ultimate failure between acetabulum outside liner and sclerotin, and adopt the fixed words of screw to need in advance on sclerotin, to punch, afterwards screw is screwed into, owing to be subjected to spatial restriction, screw to be screwed into operation very inconvenient.
The utility model content
The purpose of this utility model provides a kind of artificial hip joint acetabulum outside liner that prevents long-term loosening.
For achieving the above object, this utility model is taked following design:
Artificial hip joint acetabulum outside liner is characterized in that, it comprises: lining body and integrally formed crab-bolt from the described lining body; Described lining external surface is formed with three-dimensional dictyosome, the surface of described three-dimensional dictyosome has most by table hole inwards, described three-dimensional dictyosome inner transverse has the horizontal duct in connected component or whole described holes, described crab-bolt be by the lining body outwards protrude out form and with the lining body axis parallel, described crab-bolt quantity is one or more.
Described three-dimensional dictyosome is arranged in the whole outer surface of described lining body.
Described three-dimensional dictyosome is arranged in the local outer surface of described lining body.
Described horizontal duct is monolayer duct or multilamellar duct.
It adopts medical metal or bioceramic to make.
The surface of described three-dimensional dictyosome has hydroxyapatite coating layer.
The utility model has the advantages that:
1, this utility model artificial hip joint acetabulum outside liner, it comprises: the lining body and from the lining body on integrally formed crab-bolt; Wherein serve as a contrast external surface and be formed with three-dimensional dictyosome, the surface of three-dimensional dictyosome has most by table hole inwards, and three-dimensional dictyosome inside has the horizontal duct in connected component or whole holes.Therefore, after the patient installs artificial hip joint acetabulum outside liner, in the hole of the chimeric three-dimensional dictyosome of growing into of osteocyte meeting and the duct and around locking, reach the effect that prevents effectively that muchly generation is become flexible between artificial hip joint acetabulum outside liner and sclerotin.
2, this utility model artificial hip joint acetabulum outside liner, wherein crab-bolt is outwards to be protruded out by the lining body to form, at first patient's acetabular fossa is cleared up operation Shi doctor, after waiting to expose spongy bone this utility model artificial hip joint acetabulum outside liner is squeezed into specific purpose tool, make crab-bolt embedding acetabular fossa spongy bone and make the three-dimensional dictyosome of artificial hip joint acetabulum outside liner tightly push the interior spongiosa surface of bone of acetabular fossa, the postoperative artificial hip joint acetabulum outside liner will be at first obtains the stable of initial stage by crab-bolt, treats that grow into gradually artificial hip joint acetabulum outside liner behind the hole that is connected of three-dimensional dictyosome and the duct of sclerotin will obtain to stablize good long term effect to prevent to become flexible.It is very convenient to this shows that this utility model artificial hip joint acetabulum outside liner installs, and the crab-bolt on the lining body is not easy to fracture.
3, this utility model artificial hip joint acetabulum outside liner can make three-dimensional dictyosome be arranged in the whole outer surface or the local outer surface of lining body according to the difference of patient's sclerotin damaged condition and the needs of biomechanics.
4, this utility model artificial hip joint acetabulum outside liner, wherein laterally the duct is the monolayer duct, if look darker and sclerotin is connected more firm then adopts the multilamellar duct with artificial hip joint acetabulum outside liner for the ease of sclerotin.
5, this utility model artificial hip joint acetabulum outside liner, wherein the surface of three-dimensional dictyosome has hydroxyapatite coating layer, has the function of inducing osteocyte to grow into.
