1. artificial knee joint prosthesis sleeve pipe implant, described joint has the joint motions surface, and described sleeve pipe comprises:

  • Main body, described main body has central longitudinal axis, middle part, first flank part, second flank part of qualification first end and second end and limits along the inwall of the passage of described central longitudinal axis, and described passage is tapered between described first end and described second end;

    Described main body has and comprises a plurality of adjacent stagewise outer surfaces, and each ladder all has around its peripheral outward flange, and each stagewise described outward flange is positioned at the plane of the described central longitudinal axis that is substantially perpendicular to described main body;

    Described middle part in described main body, each stagewise described outward flange comprises a pair of have the same curvature radius, diametrically opposite sweep, the center of curvature of each described diametrically opposite sweep distributes along the described central longitudinal axis of described main body, and described diametrically opposite sweep defines the described outer peripheral summit of the described center of described main body;

    The described first flank part in described main body, each stagewise described outward flange comprises a pair of relative and isolated straight line, described straight line is connected to described diametrically opposite sweep, and by linking to each other with the isolated bent back ends section of the described diametrically opposite sweep at described middle part, distance between the described outer peripheral described relative and isolated straight line of the described first flank section office is less than the distance between the described outer peripheral described diametrically opposite sweep of the described center of described main body, and described bent back ends section defines the described outer peripheral summit of the described first flank section office of described main body;

    The described second flank part in described main body, each stagewise described outward flange comprises a pair of relative and isolated straight line, described straight line is connected to the described diametrically opposite sweep of the described center of described main body, and by linking to each other with the isolated bent back ends section of described diametrically opposite sweep, distance between the described outer peripheral described relative straight line of the described second flank section office is less than the distance between the described outer peripheral described diametrically opposite sweep of the described center of described main body, and described bent back ends section defines the described outer peripheral summit of the described second flank section office of described main body;

    Each ladder has between first lateral dimension between the described outer peripheral described summit of described first flank part and the described second flank described outer peripheral described summit partly, and second lateral dimension between the described summit of the described outer peripheral described diametrically opposite sweep at described middle part;

    AndWherein, described stagewise described first lateral dimension of the most close described first end is greater than adjacent stagewise described first lateral dimension, and described stagewise described second lateral dimension of the most close described first end is greater than adjacent stagewise described second lateral dimension.
