DEVICE AND METHOD FOR PREPARING BONE TUNNEL FOR ANTERIOR CRUCIATE LIGAMENT RECONSTRUCTION

摘要

A device for preparing a bone tunnel at the distal end of a femur for the reconstruction of an anterior cruciate ligament (ACL), applied when preparing a femoral tunnel when ACL reconstruction is performed. The device comprises a striking region (110), a connective rod (120) and a bone tunnel preparation component (130). The bone tunnel preparation component (130) is for preparing a bone tunnel, and is a cylinder with an oval-shaped traverse section and a U-shaped longitudinal section. The open end of the U-shaped section is connected to one end of connective rod (120), and the other end of connective rod (120) is connected to the striking site (110) which provides a striking plane (111) perpendicular to the direction of extension of the connective rod (120). The preparation device can prepare the distal end of an oval-shaped femoral tunnel for reconstructing the ACL, matching the shape of an ACL material before reconstruction and being more similar anatomically to ACL, making the function of the reconstructed ACL more similar physiologically to the function of the real ACL.
