Systems and methods for navigating a pin guide driver
Systems and methods for resecting a knee joint using a navigated pin guide driver system. The navigated pin guide driver system communicates with a navigation system to aid a user in placing cut block pins into the knee joint. The navigated pin guide driver system may include a handle, a reference element that electronically communicates with the navigation system, one or more pin guide tubes that may correspond to one or more cut blocks, and a distal tip that is configured to attach to the bone.
1. A navigated pin guide driver system, comprising:
a handle;
a first pin guide tube having a through hole for receiving a first pin;
a reference element including a plurality of markers arranged in a predetermined pattern and attached to the first pin guide tube, the reference element configured to be tracked by a navigation system; and
a tubular distal tip coupled to a distal end of the first pin guide tube, the distal tip having a through hole for receiving the first pin and configured to dock into cortical bone;
a bridge having a first end attached to the first pin guide tube; and
a second pin guide tube having a through hole for receiving a second pin and spaced from the first pin guide tube such that the first and second pins receive corresponding holes in a cut block for cutting a femur or tibia, wherein the first pin guide tube, the second pin guide tube, the bridge and the reference element is configured to rotate about the tubular distal tip.
2. The system of claim 1 , wherein the first pin guide tube is parallel to the second pin guide tube.
3. The system of claim 2 , wherein the first pin guide and the second pin guide extend vertically laterally from the bridge.
4. The system of claim 3 , wherein the bridge is configured to maintain a spacing between the first pin guide tube and the second pin guide tube.
5. The system of claim 4 , wherein the spacing corresponds to corresponding holes of a femur cut block.
6. The system of claim 5 , wherein the cut block is a 4 in 1 cut block.
7. The system of claim 4 , wherein the cut block is a proximal tibial cut block.
8. The system of claim 1 , wherein the reference element includes optical markers configured to be tracked by the navigation system.
