Abstract
The invention discloses an improved metal acetabulum outer cup for an artificial hip joint. The improved metal acetabulum outer cup is characterized in that the cup is made by casting or forging, and a rough medical metal lamina is formed on a corresponding surface, contacting with bones of a patient, of the acetabulum outer cup by material increase manufacturing. Owing to casting and forging, strength and mechanical properties of the acetabulum outer cup are guaranteed; by means of material increase manufacturing, proper roughness can be set for the rough lamina to maximally benefit bone attachment or bone ingrowth. The improved metal acetabulum outer cup is applicable to bone joint replacement surgeries for lesions of hip joints of human bodies.
Description
Technical field
The present invention 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
Artificial hip joint acetabular outer cup is body implant, the alternative of implant into body hip joint when needing to carry out orthopaedics replacement operation for human hip pathological changes, make patient recover the physiological function of hip joint to a certain extent, alleviating pain, improve motion and improve the quality of living.
In prior art, make artificial hip joint acetabular outer cup by casting or forging, after form coarse thin layer through sandblasting at cup (1), or hydroxyapatite or titanium are formed coarse thin layer by thermal spraying at cup (1); Also artificial hip joint acetabular outer cup and rough surface thin layer is made into integration by increasing material manufacture.But by casting and forge the artificial hip joint acetabular outer cup of formation, the roughness 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 artificial hip joint acetabular outer cup 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, causes the risk having fracture and second operation in implant.
Summary of the invention
The object of the present invention is to provide a kind of artificial hip joint acetabular outer cup of improvement, under the prerequisite ensureing mechanical property and mechanical strength, the surface roughness with Bone Ingrowth can be depended on for the most applicable bone of acetabular outer cup customization, overcome the defect easily loosening and may rupture after existing artificial hip joint acetabular outer cup is implanted.
Task of the present invention realizes by this way:
A kind of artificial hip joint acetabular outer cup, first makes by casting or forging, then is manufactured on cup (1) by increasing material and forms coarse medical metal thin layer (2), and customizes optimum surface roughness for this coarse thin layer.
Can according to the sclerotin difference of patient and biomechanics requirement, for patient customizes coverage rate and the surface roughness of coarse thin layer.
Coarse thin layer (2) is distributed in the respective surfaces that cup (1) contacts with patient's sclerotin, can cover the surface of 1% ~ 99%;
The average surface roughness Ra scope of coarse thin layer (2) is 3.2 ~ 1250.
Advantage of the present invention is: the present invention makes artificial hip joint acetabular outer cup by casting or forging, and ensure that intensity and the mechanical property of acetabular outer cup.Be fabricated to coarse thin layer (2) by increasing material again and customize optimum surface roughness, bone can be conducive to substantially and depend on and Bone Ingrowth.
Accompanying drawing explanation
fig. 1for embodiment of the present invention structural representation
figure (wherein coarse thin layer is distributed in the part surface of cup).
Detailed description of the invention
as Fig. 1shown in, the invention provides a kind of artificial hip joint acetabular outer cup, make by casting or forging.Then set up the coarse thin film model with optimum surface roughness (such as Ra=400) in a computer, then by laser or high-power electron beam melting medical metal powder, this artificial hip joint acetabular outer cup obtains required coarse thin layer.
Claims (1)
1. the artificial hip joint acetabular outer cup of the coarse thin layer of band improved, is characterized in that making by casting or forging, then is manufactured on cup (1) and goes up the respective surfaces contacted with patient's sclerotin by increasing material and form coarse medical metal thin layer (2); The coverage of this coarse 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 surface roughness of this coarse medical metal thin layer (2) can customize, and average surface roughness Ra scope is 3.2 ~ 1250.
