摘　　要：本文阐述了一种前交叉韧带股骨端单隧道双束重建分隔钉的研制过程。该分隔钉呈流线型,横截面呈水滴状,侧方有突出的分束翅片,翅片尾端有防滑齿,相对侧有抗旋防滑齿。采用分隔钉能使肌腱更靠近解剖止点受力区,尽可能增大肌腱在足印区的分布面积,更好的达到解剖重建的要求,配合带袢钢板使用,在保证良好固定力的同时,将肌腱重新分布于解剖功能位置。This paper elaborated the development of a separate nail for single-tunnel double-bundle femoral-end reconstruction of ACL（Anterior Cruciate Ligament）. The separate nail was streamlined and teardrop-shaped on the cross section and had protuberant splitting fin on the side. At the end of splitting fin, skid-proof gears were seen; while, on the opposite side, anti-rotation skid-proof gears were designed. By using the separate nail, the tendon was closer to stess zone of anatomic stop, and the distribution area of tendon in the foot-print zone could be expanded as much as possible so as to achieve the requirement of anatomic reconstruction more likely. The combination of separate nails and the endobutton made the tendon redistributed to the anatomy-functional position and at the same time guaranteed favorable fixed force.
