    • A tool for inserting an intramedullary guide wire comprises a curved metal guide tube having a through lumen and a sharp point at its distal end, a handle for manipulating the tube, and a sighting guide affixed to the tube. The curvature of the guide tube enables the surgeon to align a drilling tool passed through the lumen with the axis of the femoral canal. The sighting guide has a straight distal portion parallel to a line tangent to the lumen axis at the distal end, so that the surgeon can better judge the position and orientation of the tip of the tool within the patient.
    • 用于插入髓内导丝的工具包括弯曲金属导管,其具有通孔和其远端处的尖锐点,用于操纵管的手柄和固定到管的瞄准引导件。 引导管的曲率使得外科医生能够使穿过内腔的钻具与股骨管的轴线对准。 瞄准引导件具有平行于在远端处与内腔轴线相切的直线的直的远端部分,使得外科医生可以更好地判断工具在患者体内的尖端的位置和取向。
