Abstract
The utility model relates to a modified area thin porous layer's outer cup of artifical hip joint metal acetabular bone, characterized by is by the casting or forge and to make, the porous medical metal thin layer of corresponding surface formation of rethread vibration material disk cup and the contact of patient's sclerotin the acetabular bone outside. Because of casting and forge intensity and the mechanical properties who has guaranteed the outer cup of acetabular bone, rethread vibration material disk is the customized optimum porosity of thin porous layer, and ability maximize ground is favorable to the bone to depend on or the bone is grown into. The utility model discloses it carries out bone total joint replacement surgery's use to be fit for the human hip pathological change.
Description
Technical field
This utility model relates to the artificial joint of medical science osteoarticular field, the metal acetabulum outer cup of artificial hip joint of particularly a kind of improvement.
Background technology
Metal acetabulum outer cup of artificial hip joint is body implant.The alternative of implant into body hip joint when needing to carry out orthopaedics replacement operation for human hip pathological changes, makes patient recover the physiological function of hip joint to a certain extent, alleviating pain after implantation, improve motion and improve the quality of living.
In prior art, make metal acetabulum outer cup of artificial hip joint by casting or forging, after form thin porous layer through sandblasting at cup (1), or hydroxyapatite or titanium are formed thin porous layer by thermal spraying at cup (1); Also metal acetabulum outer cup of artificial hip joint and porous surface thin layer is made into integration by increasing material manufacture.But by casting and forge the metal acetabulum outer cup of artificial hip joint of formation, the porosity on its surface is difficult to customization, is unfavorable for that bone depends on or Bone Ingrowth, after using certain hour, has loosening possibility, adds the mortality of replacement, the physiological load of making patients.The metal acetabulum outer cup of artificial hip joint be made into integration by the manufacture of increasing material is inadequate because of manufacturing technology Maturity, can not ensure mechanical property and the mechanical strength of acetabular outer cup, cause there is distortion in implant, loosens the risk with second operation.
Summary of the invention
The purpose of this utility model is the metal acetabulum outer cup of artificial hip joint providing a kind of improvement, under the prerequisite ensureing mechanical property and mechanical strength, the porosity with Bone Ingrowth can be depended on for the most applicable bone of acetabular outer cup customization, overcome after existing metal acetabulum outer cup of artificial hip joint is implanted and easily loosen, yielding defect.
Task of the present utility model realizes by this way:
A kind of metal acetabulum outer cup of artificial hip joint, first makes by casting or forging, then is manufactured on cup outer surface by increasing material and forms porous medical metal thin layer (2), and customizes optimum porosity for this thin porous layer.
Can according to the sclerotin difference of patient and biomechanics requirement, for patient customizes coverage rate and the porosity of thin porous layer.
Thin porous layer (2) is distributed in the respective surfaces that cup (1) contacts with patient's sclerotin, can cover the surface of 1% ~ 99%;
The mean porosities scope of thin porous layer (2) is 1% ~ 99%.
Advantage of the present invention is:
This utility model makes metal acetabulum outer cup of artificial hip joint by casting or forging, and ensure that intensity and the mechanical property of acetabular outer cup.Be manufactured on cup outer surface formation thin porous layer by increasing material again, and customize optimum porosity for thin porous layer (2), bone can be conducive to substantially and depend on and Bone Ingrowth.
Accompanying drawing explanation
Fig. 1 is this utility model example structure schematic diagram (wherein thin porous layer is distributed in the part surface of cup outer surface).
Detailed description of the invention
As shown in Figure 1, this utility model provides a kind of metal acetabulum outer cup of artificial hip joint, makes by casting or forging.Then set up the model with the thin porous layer of optimum porosity (such as 40%) in a computer, then by laser or high-power electron beam melting medical metal powder, this metal acetabulum outer cup of artificial hip joint outer surface obtains required thin porous layer.
Claims (1)
1. the metal acetabulum outer cup of artificial hip joint of band thin porous layer improved, is characterized in that making by casting or forging, then is manufactured on by increasing material the respective surfaces that cup (1) contacts with patient's sclerotin and forms porous medical metal thin layer (2); The coverage of this porous medical metal thin layer (2) can customize, and is distributed in the respective surfaces that cup (1) contacts with patient's sclerotin, can covers the surface of 1% ~ 99%; The mean porosities scope of this porous medical metal thin layer (2) is 1% ~ 99%.
