    • An acromioclavicular joint guide for forming multiple drill tunnels spaced apart by a predetermined distance employs two drill guides in a pivoting arrangement allowing one drill guide to pivot around the axis of the other. The drill guides are each disposed in a respective sleeve of a pivot block for insertion toward the surgical member along nonintersecting axes defined by the sleeve. An elongated arm attaches to the pivot block at a proximate end and has a aimer point at a distal end, in which the arm may extend around the surgical member via an inverted portion or bend such that the aimer point is on the insertion axis of the primary drill guide. In this manner the aimer point locates an exit of the hole from the insertion point defined by the primary drill guide, and the pivotal drill guide defines a second tunnel at the predetermined distance.
    • 用于形成间隔开预定距离的多个钻孔隧道的肩锁关节引导件采用两个钻孔引导器,该枢转布置允许一个钻子引导件围绕另一钻杆枢转。 钻子引导件各自设置在枢转块的相应套筒中,用于沿着由套筒限定的不间断轴线朝向外科手术构件插入。 细长臂在近端附接到枢转块,并且在远端具有瞄准器点,其中臂可以经由倒置部分或弯曲部围绕手术构件延伸,使得瞄准器点在所述插入轴线上 主钻指南。 以这种方式,瞄准器点将孔的出口从由主钻导向器限定的插入点定位,并且枢转钻子引导器以预定距离限定第二隧道。

    • 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.
