Problems solved by technology

[0005] The main purpose of the present invention is to provide a tibial platform to solve the problem in the prior art that after the inner and outer sides of the femoral condyle are worn, the gap between the femoral condyle and the spacer is different, which causes the problem of aggravated wear

Embodiment Construction

[0024] It should be noted that the embodiments in the application and the features in the embodiments can be combined with each other if there is no conflict. Hereinafter, the present invention will be described in detail with reference to the drawings and in conjunction with the embodiments.

[0025] As described in the background art, the knee joint prosthesis currently used in artificial knee replacement surgery usually uses medical metal to make femoral condyle prosthesis on the femur side, such as stainless steel or cobalt alloy, and the tibia side uses ultra-high molecular weight. Polyethylene gaskets. During the use of the knee prosthesis, the polyethylene gasket will wear out. However, in some cases, due to the different activities of the patient, the degree of wear on the inner and outer sides is different, and the gap between the femoral condyle and the gasket is different. The solution will speed up the wear of one of the gaskets and reduce the life of the patient's k...

Abstract

The invention provides a tibial plateau. The tibial plateau includes a plateau seat, tibial pads, plateau adjusting parts installed between the plateau seat and the tibial pads and adjustable supportparts; each plateau adjusting part comprises an upper shell body and a lower shell body, the tibial pads are installed on the upper shell bodies, and the lower shell bodies are installed on the plateau seat; the adjustable support parts are used to adjust the distances between the upper shell bodies and the lower shell bodies, the adjustable support parts include temperature sense pieces and heating parts, the upper ends of the temperature sense pieces support the upper shell bodies, the lower ends of the temperature sense pieces are installed on the lower shell bodies, and the temperature sense pieces can adjust their own heights according to the temperature of the heating parts. When it is necessary to adjust the heights of the plateau adjustment parts, the heating parts can work to emitheat, the heights are increased after the temperature sense pieces are heated, so as to realize the rise of the tibial pads. In the process of using the knee joint prosthesis, when the unilateral wear is severe, the tibial plateau adjustment is used to keep the gaps between the inner and outer pads and the femoral condyles in an appropriate position to ensure the service life.

Description

Technical field [0001] The present invention relates to the technical field of tibial medical equipment, in particular to a tibial platform. Background technique [0002] The knee joint is one of the important joints of the lower limbs of the human body. At the same time, knee joint disease is also a common and frequently-occurring disease in the elderly. One of its specific manifestations is joint pain caused by the wear or degeneration of articular cartilage. [0003] In the treatment of knee joint disease, the most commonly used is the surface replacement in knee arthroplasty. Specifically, a thin layer of worn cartilage and subchondral bone on the femur and tibia of the knee joint is shaved off to form an osteotomy surface, and then a cobalt-chromium-molybdenum alloy metal implant prosthesis is fixed by direct fixation or bone cement The method is fixed to the osteotomy surface to replace the worn joint bone. In the above implanted prosthesis, the component used to replace th...
