Cross pinning guide devices and methods
Methods and devices are provided for implanting a cross-pin through a bone tunnel, such as in an arthroscopic surgical procedure. In general, the methods and devices allow a cross-pin hole to be formed in a medial side of a knee bone such that it intersects a bone tunnel formed in the knee bone. In one embodiment, a cross-pinning guide device is provided that can be configured to angularly position the cross-pin hole relative to the bone tunnel to allow the cross-pin hole to intersect the bone tunnel without passing through another side, e.g., a lateral side, of the knee bone. The knee bone can be a femur or a tibia such that the cross-pin hole and the bone tunnel can each be entirely formed in the femur or in the tibia.
1. A surgical device, comprising:
a frame having a guide rod and a proximal-distal arc spaced a distance apart from the guide rod;
a guide block slidably mounted on the proximal-distal arc and having at least one bore formed therethrough that is configured to receive a first surgical instrument; and
a medial-lateral arc having a first end with an engagement mechanism configured to detachably mate the medial-lateral arc to the guide block, and a second end having one bore formed therethrough that is configured to receive a second surgical instrument;
wherein, with the medial-lateral arc mated to the guide block, the at least one bore formed through the guide block is coaxial with the at least one bore formed through the second end of the medial-lateral arc.
2. The device of claim 1 , wherein the proximal-distal arc extends in a direction substantially parallel to a direction of the guide rod.
3. The device of claim 1 , wherein the engagement mechanism is matable with the guide block in a first orientation relative to the guide block and in a second orientation relative to the guide block that differs from the first orientation.
4. The device of claim 1 , wherein, with the medial-lateral arc mated to the guide block, the medial-lateral arc is positioned in a plane that is substantially perpendicular to a plane containing the proximal-distal arc.
5. The device of claim 1 , wherein, with the guide block at any slidable position along the proximal-distal arc, a longitudinal axis of the at least one bore formed through the guide block extends through an opening formed in a distal portion of the guide rod.
6. A surgical device, comprising:
a frame having a guide rod and a proximal-distance arc spaced a distance apart from the guide rod;
a guide block slidably mounted on the proximal-distal arc and having at least one bore formed therethrough that is configured to receive a first surgical instrument; and
a medial-lateral arc having a first end with an engagement mechanism configured to detachably mate the medial-lateral arc to the guide block, and a second end having at least one bore formed therethrough that is configured to receive a second surgical instrument;
wherein the at least one bore formed through the guide block comprises first and second bores, the at least one bore formed through the second end of the medial-lateral arc comprises third and fourth bores, and with the medial-lateral arc mated to the guide block, the first bore is coaxial with the third bore and the second bore is coaxial with the fourth bore.
7. The device of claim 6 , wherein the proximal-distal arc extends in a direction substantially parallel to a direction of the guide rod.
8. The device of claim 6 , wherein the engagement mechanism is matable with the guide block in a first orientation relative to the guide block and in a second orientation relative to the guide block that differs from the first orientation.
9. The device of claim 6 , wherein, with the medial-lateral arc mated to the guide block, the medial-lateral arc is positioned in a plane that is substantially perpendicular to a plane containing the proximal-distal arc.
10. The device of claim 6 , wherein, with the guide block at any slidable position along the proximal-distal arc, a longitudinal axis of the first bore and a longitudinal axis of the second bore extend through an opening formed in a distal portion of the guide rod.
