Abstract
The invention discloses a mixed knee-joint prosthesis system which comprises a femoral condyle prosthesis, a tibial plateau prosthesis and an extending handle body, wherein the femoral condyle prosthesis comprises an articular surface, a condyle joint surface, a thigh marrow inner handle and an intercondyloid joint surface; the tibial plateau prosthesis comprises a plateau body, a filling sleeve and a triangular pterygoid lamina; the upper end of the extending handle body is stretched into the filling sleeve of the tibial plateau prosthesis or the thigh marrow of the femoral condyle prosthesis for connection and fixing; the femoral condyle prosthesis and the tibial plateau prosthesis are designed to be fixed by bone cement; the extending handle body is designed not to be fixed by bone cement. The inner surface of the femoral condyle prosthesis, as well as the inner surface and outer surface of the tibial plateau prosthesis are subjected to high polishing design. The mixed knee-joint prosthesis system has the following advantages: the postoperation overhaul rate is decreased, the stress of a support surface below the prosthesis is dispersed, a great amount of bone cement is prevented from being used in marrow, the operation involved range is reduced, and the extending handle is prevented from penetrating through a pulp cavity to cause more serious injury.
Description
Technical field
The invention belongs to Design for Medical Device technical field, especially relate to a kind of mixing knee joint prosthesis system.
Background technology
At present, indication mainly knee joint osseous arthritis (OA) and the knee rheumatoid arthritis (RA) of total knee arthroplasty (TKA), knee joint OA and RA causes the wear-out failure of knee cartilage layer in various degree, thus causes kneed pain and changing function.
TKA is after articular surface impaired for knee joint and knee cartilage being excised, at the new artificial prosthesis movable articular surface can being installed alternative knee joint function that subchondral bone layer is formed.
Within 1973, Freeman has sketched the contours the target of knee-joint prosthesis design:
1. retain the chance of Salvage surgery, large-area platform spongy bone bed should be retained;
2. the probability loosened is reduced to minimum;
3. the generation rate of abrasive dust should be minimum;
4. prosthetic designs and installation should reduce dead space as far as possible, the probability of infection are minimized;
5. avoid using a large amount of bone cement in marrow;
6. installation process should standardization.
Above clause is still effective so far.For effectively realizing above target, reach simultaneously the postoperative long-term safety of TKA effectively, reduce the incidence rate loosened, the articular surface partial design of artificial knee joint prosthesis is cement reaction by we, and kneed prolonging handle body divides and is designed to none-cement and fixes.
Summary of the invention
The problem to be solved in the present invention is to provide the postoperative revision rate of a kind of reduction, dispersion prosthese supported underneath face stress, avoid a large amount of Cement in marrow, reduce operation and to get involved scope, avoid prolonging handle to pass mixing knee joint prosthesis system that pulp cavity causes larger damage.
For solving the problems of the technologies described above, the technical solution used in the present invention is: a kind of mixing knee joint prosthesis system, comprises lateral femoral condyle prosthesis, tibial plateau prosthese and prolonging handle body; Described lateral femoral condyle prosthesis to comprise in articular surface, condyle faying face, femur marrow faying face between handle and condyle, described articular surface and condyle faying face are structure as a whole, described condyle faying face centre position is provided with faying face between condyle, between described condyle, faying face is provided with handle in femur marrow; Described tibial plateau prosthese comprises platform body, fills cover and triangle wing plate, and described filling cover is the column structure of hollow, and this filling cover is arranged at below platform body; Described triangle wing plate is symmetricly set in fills cover both sides; Be connected and fixed in handle in the filling cover that tibial plateau prosthese is stretched in described prolonging handle body upper end or in the femur marrow of lateral femoral condyle prosthesis; Described lateral femoral condyle prosthesis and tibial plateau prosthetic designs are cement reaction, and described prolonging handle body is designed to none-cement and fixes, and collectively form the fixing lateral femoral condyle prosthesis of bone cement and biological mixed type and tibial plateau prosthese.
The inner surface of described lateral femoral condyle prosthesis, the inner surface of tibial plateau prosthese and outer surface are high polishing design.
In described femur marrow, handle and prolonging handle body are the design of band longitudinal ridge burr.
In described femur marrow, handle and prolonging handle body far-end design for round end.
Owing to adopting technique scheme, (1) knee-joint prosthesis articular surface, namely the articular surface of lateral femoral condyle prosthesis of the present invention and tibial plateau prosthese is bone cement design, reduce postoperative revision rate, Swedish National register system data show, and the revision rate of knee-joint prosthesis articular surface none-cement fixed fae body exceeds 1.4 times than cement reaction type; (2) should consider when the bone support strength below prosthese is inadequate to use prolonging handle body, in use marrow, the object of prolonging handle body is the stress in order to disperse prosthese supported underneath face, and the people such as Brooks prove that tibial prosthesis prolonging handle can bear the body weight of about human body 30%; (3) avoid a large amount of Cement in marrow, reduce operation and to get involved scope.
The invention has the beneficial effects as follows: have and reduce postoperative revision rate, dispersion prosthese supported underneath face stress, avoid a large amount of Cement in marrow, reduce operation and to get involved scope, avoid prolonging handle to pass advantage that pulp cavity causes larger damage.
