Therefore, at present a lot of doctors and those skilled in the art advise the anatomical form tibial plateau prosthese of a kind of bionical attitude of manufacturer production.
Summary of the invention
Purpose of the present invention just is to provide a kind of bionical attitude anatomical form tibial plateau prosthese that can overcome above-mentioned defective.
To achieve these goals, the present invention has adopted following structure: a kind of anatomical form tibial plateau prosthese, it includes platform holder and three aerofoil profile fixed legs, and wherein said platform holder includes the platform body and projects upwards in the flange of platform body, and described flange has interior edge and outer; Described flange is divided into leading edge and trailing edge, forms a plurality of flange draw-in grooves along the place in the described leading edge, and described trailing edge is divided into left side trailing edge and right side trailing edge, and the interior of described left side trailing edge and right side trailing edge all forms inner groovy along the place.
Further, a side of the leading edge of described platform holder has outstanding radian, thereby meets the cross section of human tibia more.
Further, form three flange draw-in grooves along the place in the described leading edge
Further, described three aerofoil profile fixed legs are distributed with three wings at vertical circumference.
Further, because anatomical form tibial plateau prosthese of the present invention is asymmetric, thus can not the left and right sides general, so its branch about having.
Adopted the tibial plateau prosthese of said structure, the design of its flat surface can with human tibia platform osteotomy surface Perfect Matchings, realized the cortical bone supporting prostheses, effectively reduced the prosthese sinking, the final purpose that realizes reducing repair rate.And because the anatomical form tibial prosthesis is asymmetric design, the branch about having, and when installing, be difficult for prosthese is installed to the inward turning position, only prosthese need be overlapped as much as possible with the tibia osteotomy surface, can guarantee correct para-position and the line of force.
