摘要：【中文】本发明提供一种关节假体组件，包括卡环、内衬和外杯，所述内衬和所述外杯均为杯状结构，所述内衬安装在外杯内，所述卡环为非连续的环状结构，所述卡环安装于内衬内，所述内衬的边缘高于外杯的边缘。本发明卡环安装于内衬内，避免了卡环与外杯直接接触带来的磨损风险。所述内衬的边缘高于外杯的边缘，避免了股骨柄与外杯的直接接触，防止其产生硬对硬的碰撞。 【EN】The invention provides a joint prosthesis assembly which comprises a clamping ring, an inner liner and an outer cup, wherein the inner liner and the outer cup are of cup-shaped structures, the inner liner is arranged in the outer cup, the clamping ring is of a discontinuous annular structure, the clamping ring is arranged in the inner liner, and the edge of the inner liner is higher than that of the outer cup. The clamping ring is arranged in the lining, so that the abrasion risk caused by direct contact of the clamping ring and the outer cup is avoided. The edge of the inner liner is higher than that of the outer cup, so that the femoral stem is prevented from being in direct contact with the outer cup, and hard-to-hard collision is prevented.
