Embodiment Construction

[0018] Exemplary configurations and deployments of the surgical aimer arm are disclosed below. In an exemplary arrangement, an ACL repair using a surgical targeting device for femoral drilling is shown. Alternative configurations may employ placement on other bone structures or on softer tissue surfaces, and may or may not employ a drilling method to excavate the insertion tunnel for the guide wire.

[0019] figure 1 A side view of a surgical targeting device 100 is shown that includes a handle 102 having a slot 104 defining an arc 106 . Handle 102 is shaped for a secure grip by a surgeon or other operator. Arm 110 has an arcuate section 112 and a straight section 114 . Arc section 112 is shaped to slidably engage slot 104 in handle 102 according to arrow 116 . Straight section 114 has a hinge 120 for securing sight 130 to straight section 114 at an opposite end distal to arcuate section 112 . Hinge 120 accommodates sight 130 in rotational communication with flat section ...

Abstract

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.

Description

[0001] Cross References to Related Applications [0002] This application is a PCT International Patent Application claiming priority to US Patent Application Serial No. 13 / 016081 filed January 28, 2011, the disclosure of which is incorporated herein by reference in its entirety. Background technique [0003] Reconstructive bone and ligament surgery often involves drilling into skeletal components to attach connecting elements, such as ligament and tendon grafts and various artificial replacements and / or attachments for articulation. In particular, reconstructive surgery involving the anterior cruciate ligament (ACL) is becoming increasingly important because the effectiveness of the reconstruction can have a profound impact on the patient's subsequent mobility. For example, effective ACL repair in professional athletes can save an otherwise career-ending injury. Similarly, an improperly treated ACL injury can be permanent damage even in amateur athletes.
