    • A hinged pivoting guide for positioning a femoral tunnel in anterior cruciate ligament (ACL) reconstruction locates a drilling hole for placement that optimally penetrates a minimal depth of soft tissue (skin, muscle, etc.) yet directs drilling into a sufficiently rigid and structurally sound area of the femur. The hinged guide allows placement of an aimer point at a desired drilling exit location on the femur. The hinge is adapted to secure the aimer at a degree of rotation about an axis defined by the hinge rotation, such that the axis passes through the aimer point throughout rotation of the hinge while maintaining the aimer point in line with an insertion guide slideably movable through the aperture in the handle, the aperture defined by an insertion axis extending toward the aimer point such that the aimer point remains disposed at the intersection of the hinge axis and the insertion axis.
    • 用于将股骨隧道定位在前十字韧带(ACL)重建中的铰接枢转引导器定位用于放置的钻孔,其最佳地穿透软组织(皮肤,肌肉等)的最小深度,但是将钻孔引导到足够刚性和结构声音 股骨面积 铰链引导件允许将瞄准器点放置在股骨上期望的钻孔出口位置。 铰链适于将瞄准器固定在围绕由铰链旋转限定的轴线的旋转角度处,使得轴线在铰链旋转期间通过瞄准器点,同时保持瞄准器点与可滑动地移动的插入导向 手柄中的孔径,由朝向瞄准器点延伸的插入轴限定的孔,使得瞄准器点保持设置在铰链轴线和插入轴线的交叉点处。
