Abstract
The invention discloses a flexible knee joint prosthesis. The flexible knee joint prosthesis comprises a femoral condyle prosthesis and a tibial plateau, wherein a flexible gasket is arranged between the femoral condyle prosthesis and the tibial plateau and fixed to the tibial plateau, and the flexible gasket supports the femoral condyle prosthesis and deforms adaptively along with the rotation of the femoral condyle prosthesis to maintain surface contact with the femoral condyle prosthesis. Due to the fact that the flexible gasket is prepared from ultrahigh molecular weight polyethylene, the articular surface can deform to adapt to and conform to the flexion and rotation deformation of the femoral condyle prosthesis under pressure, and then abrasion of the tibial plateau is relieved remarkably.
Description
Technical field
The present invention relates to a kind of flexible knee-joint prosthesis, be specifically related to apply the flexible gasket between human body knee joint position lateral femoral condyle prosthesis and tibial plateau.
Background technology
Knee-joint prosthesis used in artificial knee replacement surgery, generally uses medical metal to make lateral femoral condyle prosthesis, such as rustless steel or cobalt alloy in femur side, and tibial side then uses ultrahigh molecular weight polyethylene to make pad (tibial plateau)；The lateral femoral condyle prosthesis metal joint face that needs for motion of knee joint typically can be designed to the continuous space curved surface of complexity, but the curved surface of the higher goodness of fit, stablizing during to ensure upright is had when the ultra-high molecular weight polyethylene articular surface pad of tibial side then can only be designed to a certain ad-hoc location (such as orthostatism) with femur side articular surface.
But when knee joint starts curvature movement, the contact area on upper and lower two surfaces can drastically reduce the even the most surplus contact line on some situation theory, and at this moment local pressure can be the highest, and this is also the major reason causing articular surface abrasion to be accelerated.
Summary of the invention
For problems of the prior art, it is an object of the invention to provide a kind of flexible knee-joint prosthesis, flexible gasket is set between lateral femoral condyle prosthesis and tibial plateau, flexible gasket uses ultrahigh molecular weight polyethylene to become, articular surface can be deformed the postrotational deformation of lateral femoral condyle prosthesis flexing that adapts to and fit under pressure, thus significantly reduces the abrasion to tibial plateau.
To achieve these goals, the present invention is by the following technical solutions:
Flexible knee-joint prosthesis, including lateral femoral condyle prosthesis and tibial plateau, it is provided with flexible gasket between described lateral femoral condyle prosthesis and tibial plateau, flexible gasket is fixed on tibial plateau, flexible gasket supports lateral femoral condyle prosthesis, along with the rotation of lateral femoral condyle prosthesis, described flexible gasket produces adaptability deformation, and keeping with the contact site of lateral femoral condyle prosthesis is that face contacts.
Further, described flexible gasket is ducted body, and inner chamber is full of filling liquid.
Further, described flexible gasket uses ultrahigh molecular weight polyethylene to become, and described filling liquid uses normal saline or purified water.
Further, described flexible gasket is provided with fabric reinforcement.
Further, described flexible gasket includes housing and capping, and capping is provided with hand-hole and steam vent, seals described hand-hole and steam vent after inner chamber injects filling liquid.
Further, use bonding agent involutory bonding described capping and housing, or use ultrasonic bonding that two parts docking is formed airtight internal cavities.
Further, described tibial plateau being provided with fixing groove, described flexible gasket is arranged in described fixing groove.
Further, described flexible gasket, with shirt rim, shirt rim arranges connecting hole, is fixed by screws on tibial plateau.
The flexible knee-joint prosthesis using said structure to arrange has the advantage that
Along with the rotation of lateral femoral condyle prosthesis, pad sector-meeting produces adaptability deformation, and keeping with the contact site of lateral femoral condyle prosthesis is that face contacts, and thus significantly reduces the abrasion to tibial plateau, and the abrasion to flexible gasket self is the slightest.
The present invention extends the service life of knee-joint prosthesis, it is possible to reduce patient's post-operative number of times, alleviates the misery of patient, and saves medical expense for patient.
Although flexible gasket is hollow, due to the incompressible characteristic of liquid, so the deformable upper surface of ultra-high molecular weight polyethylene articular surface pad still can obtain enough support forces by liquid in cavity.
Owing to have employed flexible gasket, prosthese has cushioning effect, it is possible to alleviate the differences of Physiological of knee-joint prosthesis and human body, improve the adaptability to prosthese.
