1. an artificial knee joint prosthesis sleeve pipe implant, described joint has joint motions surface, instituteState prosthese sleeve pipe implant to include:

  • Main body, described main body have restriction the first end and the central longitudinal axis of the second end, inPortion, shoulder portion and restriction are along the inwall of the passage of described central longitudinal axis, and described passage existsIt is tapered between described first end and described second end;

    Described main body has the outer surface including multiple adjacent steps, and each ladder is respectively provided with around itThe outward flange of periphery, the described outward flange of each ladder is positioned at and is substantially perpendicular to the described of described main bodyIn the plane of central longitudinal axis;

    At the described middle part of described main body, the described outward flange of each ladder includes a pair having identicalSweep radius of curvature, diametrically opposite, each described diametrically opposite sweepThe center of curvature is distributed along the described central longitudinal axis of described main body, described diametrically opposite bendingThe described outer peripheral summit of the described center of partially defined described main body;

    At the described shoulder portion of described main body, the described outward flange of each ladder include a pair relativeAnd spaced apart straight line, described straight line is connected to described diametrically opposite sweep, and passes throughThe bent back ends section spaced apart with the described diametrically opposite sweep at described middle part is connected, instituteState the distance between the described outer peripheral described relative and spaced apart straight line of flank section office less than instituteBetween the described outer peripheral described diametrically opposite sweep of the described center stating main body away fromFrom, described bent back ends section defines the described outer peripheral of the described flank section office of described main bodySummit;

    Each ladder has between the described outer peripheral described summit of described shoulder portionOne lateral dimension, and the described outer peripheral described diametrically opposite bending section between described middle partThe second lateral dimension between the described summit divided;

    AndWherein, described first lateral dimension near the described ladder of described first end is more than adjacentDescribed first lateral dimension of ladder, near described second horizontal stroke of the described ladder of described first endDescribed second lateral dimension of adjacent steps it is more than to size,It is non-pooled scarce that the outer surface of wherein said main body is configured in one of filling knee joint osseous tissueDamage.
