Abstract

The utility model relates to a modified area thin porous layer's artificial knee joint femoral prosthesis, characterized by is made by casting or forging, and rethread vibration material disk forms porous medical metal thin layer at femoral prosthesis with the corresponding surface that patient's sclerotin contacted. Because of casting and forging intensity and the mechanical properties who has guaranteed femoral prosthesis, rethread vibration material disk is thin porous layer customization optimum aperture, 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 knee joint pathological change.

Description

A kind of artificial knee-joint thighbone prosthese of band thin porous layer of improvement
Technical field
This utility model relates to the artificial joint of medical science osteoarticular field, the artificial knee-joint thighbone prosthese of particularly a kind of improvement.
Background technology
Artificial knee-joint thighbone prosthese is body implant, the alternative being implanted in human femur under loading end when carrying out orthopaedics replacement operation is needed for human body knee joint pathological changes, make patient recover kneed physiological function to a certain extent, alleviating pain, improve motion and improve the quality of living.
In prior art, make artificial knee-joint thighbone prosthese by casting or forging, after form thin porous layer through sandblasting on femoral prosthesis surface, or hydroxyapatite or titanium are formed thin porous layer by thermal spraying on femoral prosthesis surface; Also artificial knee-joint thighbone prosthese and porous surface thin layer is made into integration by increasing material manufacture.But by casting and forge the artificial knee-joint thighbone prosthese of formation, the aperture 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 knee-joint thighbone prosthese 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 femoral prosthesis, causes the risk having fracture and second operation in implant.
Summary of the invention
The purpose of this utility model is the artificial knee-joint thighbone prosthese providing a kind of improvement, under the prerequisite ensureing mechanical property and mechanical strength, the aperture with Bone Ingrowth can be depended on, the defect easily loosening after overcoming existing artificial knee-joint thighbone Using prosthesis and may rupture for the most applicable bone of femoral prosthesis customization.
Task of the present utility model realizes by this way:
A kind of artificial knee-joint thighbone prosthese, first makes by casting or forging, then is manufactured on femoral prosthesis surface formation porous medical metal thin layer (2) by increasing material, and customizes optimum aperture for this thin porous layer.
Can according to the sclerotin difference of patient and biomechanics requirement, for patient customizes coverage rate and the aperture of thin porous layer.
Porous medical metal thin layer (2) is distributed in the respective surfaces that femoral prosthesis contacts with patient's sclerotin, can cover the surface of 1% ~ 99%;
The average pore size scope of porous medical metal thin layer (2) is 1 ~ 999 micron.
Advantage of the present invention is:
This utility model makes artificial knee-joint thighbone prosthese by casting or forging, and ensure that intensity and the mechanical property of femoral prosthesis.Be fabricated to porous medical metal thin layer (2) by increasing material again and customize optimum aperture, 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 (thin porous layer is distributed in the part surface of femoral prosthesis).
Detailed description of the invention
As shown in Figure 1, this utility model provides a kind of artificial knee-joint thighbone prosthese, makes by casting or forging.Then set up the model with the thin porous layer in optimum aperture (such as 200 microns) in a computer, then by laser or high-power electron beam melting medical metal powder, this artificial knee-joint thighbone prosthese obtains required thin porous layer.

Claims (1)

1. the artificial knee-joint thighbone prosthese (1) 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 femoral prosthesis 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 femoral prosthesis contacts with patient's sclerotin, can cover the surface of 1% ~ 99%; The average pore size scope of this porous medical metal thin layer (2) is 1 ~ 999 micron.
