本发明涉及植入人体的人工韧带，尤其是与钮扣钢板连接的人工韧带，具体地，涉及分段式环状悬吊人工韧带及其制备方法。The invention relates to an artificial ligament implanted into a human body, in particular to an artificial ligament connected with a button steel plate, in particular to a segmented annular suspension artificial ligament and a preparation method thereof.
背景技术Background technique
目前，全世界临床应用较多且较为成熟的人工韧带为法国的LARS人工韧带，此韧带以高韧性聚对苯二甲酸乙二醇酯（PET）为原料。1994年开始应用于临床，2004年首次在国内成功使用，已通过欧洲CE认证和中国SFDA认证。LARS人工韧带是由聚合纤维网自身卷绕合拢形成，分为两边骨隧道部、中间关节纤维部以及两端牵引线部。LARS人工韧带植入骨隧道时，在股骨及胫骨隧道内分别采用一枚金属螺钉挤压固定。但是，这种固定方式不仅减少了韧带与骨隧道的接触面积，且因螺钉对韧带的挤压导致韧带内部空间减少，影响自体组织长入，远期骨隧道内螺钉容易发生松动，最终导致人工韧带的失败。At present, the most mature artificial ligament in the world is the French LARS artificial ligament, which is made of high-toughness polyethylene terephthalate (PET). It began to be used clinically in 1994, and was successfully used in China for the first time in 2004. It has passed the European CE certification and the Chinese SFDA certification. The LARS artificial ligament is formed by winding and closing the polymer fiber net itself, and is divided into bone tunnel parts on both sides, joint fiber parts in the middle and traction wire parts at both ends. When the LARS artificial ligament is implanted in the bone tunnel, a metal screw is pressed and fixed in the femoral and tibial tunnels respectively. However, this fixation method not only reduces the contact area between the ligament and the bone tunnel, but also reduces the internal space of the ligament due to the extrusion of the screw on the ligament, which affects the growth of autologous tissue. Failure of the ligaments.

In ACL reconstruction surgery, according to the needs, select the corresponding length of the button plate with rings to connect with the loops between the two femoral tunnels of the artificial ligament. When the artificial ligament is implanted into the bone tunnel, the end of the femoral tunnel is suspended and fixed by connecting the button plate with the artificial ligament. Because the contact area between the ligament and the bone tunnel in the femoral and tibial tunnel is increased to a greater extent, and the internal space of the ligament is larger (no screw extrusion), the purpose of strengthening the fixation can be achieved.
