Abstract

The invention provides a knee joint prosthesis, which comprises a tibial platform part, an extension handle and a filling component, wherein the filling component is arranged between the tibial platform part and the extension handle to connect the tibial platform part and the extension handle; the filling component comprises a first adjusting part and a filling piece, the first adjusting part andthe filling piece are detachably connected, the first adjusting part is used for connecting with the extension handle, and the filling piece is used for connecting with the tibial platform part; and the filling piece comprises a second adjusting part, the second adjusting part comprises a telescopic part, and the telescopic part is movably arranged to increase the area of the outer peripheral surface of the second adjusting part by pushing the telescopic part to move, so as to enable the outer peripheral surface of the second adjusting part to be jointed and contacted with the bone defect position of the corresponding knee joint, and thus the effect of better matching of the second adjusting part with the bone defect position of the corresponding knee joint is achieved. Therefore, the kneejoint prosthesis can meet the bone defect situation at different knee joints and has good universality.

Description

technical field [0001] The invention relates to the medical field, in particular to a knee joint prosthesis. Background technique [0002] For total knee revision, the primary replacement prosthesis and diseased bone must be removed during revision, which will cause a certain degree of bone defect, and the location and degree of bone defect vary from person to person. [0003] Knee joint prosthesis is usually used to deal with the bone defect of the total knee joint. The structure of the filling part of the existing knee joint prosthesis is relatively fixed and the flexibility is poor, which cannot be adjusted according to the position and degree of bone defect. Adjust it appropriately so that it fills well. Although it is possible to tailor the knee prosthesis to the patient so that the filling parts can better match the bone defect of each patient, so as to meet the needs of each patient, the custom-made knee prosthesis takes a long time and is expensive. And custom-made...
