Abstract

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.

First claim

What is claimed is:

1 . A navigated pin guide driver system, comprising:
a handle; a first pin guide tube; a reference element attached to first pin guide tube, the reference element configured to be in electronic communication with a navigation system; and a distal tip configured to dock into cortical bone.

2 . The system of claim 1 , further comprising a second pin guide tube.

3 . The system of claim 2 , wherein the first pin guide tube is parallel to the second pin guide tube.

4 . The system of claim 3 , further comprising a bridge, wherein the first pin guide and the second pin guide are disposed on the bridge.

5 . The system of claim 4 , wherein the bridge is configured to maintain a spacing between the first pin guide tube and the second pin guide tube.

6 . The system of claim 5 , wherein the spacing corresponds to a cut block.

7 . The system of claim 6 , wherein the cut block is a 4 in 1 cut block.

8 . The system of claim 6 , wherein the cut block is a proximal tibial cut block.

9 . The system of claim 1 , further comprising the navigation system.

10 . The system of claim 9 , wherein the reference element includes optical markers configured to be visible by the navigation system.

11 . A method for performing a total knee arthroplasty surgery using a navigated pin guide driver system, said method comprising:
registering a patient to a navigation system; aligning the navigated pin guide driver system to a target area of a knee of the patient using the navigation system; driving at least one cut block pin into the target area using the navigated pin guide driver system; attaching at least one cut block over the at least one cut block pin; and performing cuts to the target area corresponding to the at least one cut block,
wherein the navigated pin guide driver system includes:
a handle;
a first pin guide tube;
a reference element attached to first pin guide tube, the reference element configured to be in electronic communication with a navigation system; and
a distal tip configured to dock into cortical bone.

12 . The method of claim 11 , further comprising a second pin guide tube.

13 . The method of claim 12 , wherein the first pin guide tube is parallel to the second pin guide tube.

14 . The method of claim 13 , further comprising a bridge, wherein the first pin guide and the second pin guide are disposed on the bridge.

15 . The method of claim 14 , wherein the bridge is configured to maintain a spacing between the first pin guide tube and the second pin guide tube.

16 . The method of claim 15 , wherein the spacing corresponds to a cut block.

17 . The method of claim 16 , wherein the cut block is a 4 in 1 cut block.

18 . The method of claim 16 , wherein the cut block is a proximal tibial cut block.

19 . The method of claim 11 , further comprising the navigation system.

20 . The method of claim 19 , wherein the reference element includes optical markers configured to be visible by the navigation system.
