    • An apparatus and method for performing a surgery, especially an ACL replacement surgery, where a flexible strand insertion rod co-operates with a U-Guide apparatus to insert a flexible strand into a tunnel formed in a bone portion and to guide a pair of drill points to form a pair of tunnels transversely to the tunnel of the insertion rod. The drill points are guided through the insertion rod and the flexible strand is held over the drill points as the transverse tunnels are formed. The insertion rod is then removed from the tunnels formed in the bone and the flexible strand is held looped over the second drill point. Subsequently, a soft tissue replacement is affixed to one end of the flexible strand and pulled over up to the first drill point with the other end of the flexible strand. The first drill point is then used to pull a cross pin through the transverse tunnel to hold the looped end of the soft tissue replacement in place. Finally, the two free ends of the soft tissue replacement are affixed to the bone completing the implantation of a soft tissue replacement.
    • 一种用于进行手术,特别是ACL替代手术的装置和方法,其中柔性股线插入杆与U型导向装置协作以将柔性股线插入形成在骨部分中的隧道中并引导一对钻头 指向横向于插入杆的隧道形成一对隧道。 钻孔被引导穿过插入杆,并且当横向隧道形成时,柔性线束被保持在钻尖上。 然后将插入杆从形成在骨中的隧道中取出,并且柔性股线环绕在第二钻点上。 随后,将软组织置换固定在柔性股线的一端,并用柔性股线的另一端拉到第一钻头。 然后使用第一钻头将十字销拉过横向隧道,以将软组织置换的环形末端保持在适当位置。 最后,将软组织置换的两个自由端固定到完成植入软组织置换的骨上。
