Abstract

A device for correcting a placement of a guide wire in a bone includes a body extending from a proximal end to a distal end; a central channel extending through the body from the proximal end to the distal end along a central axis, the central channel sized and shaped to receive a guide wire slidably therein; and a first correction channel extending through the body from the proximal end to the distal end. The first correction channel is sized and shaped to receive a guide wire therein at an angle relative to the central axis of the central axis of the central channel.

First claim

What is claimed is:

1. A method for correcting a guide wire placement in a bone, comprising:
inserting a first guide wire into a bone;
determining a desired corrected placement of the first guide wire;
inserting the first guide wire into an initial channel of a device along an initial axis;
sliding the device along the first guide wire until a distal end thereof abuts a surface of the bone; and
inserting a second guide wire through a correction channel of the device, the correction channel being oriented, when the device is received over the first guide wire, to direct the second guide wire into the bone along a correction axis of insertion corresponding to the desired corrected placement of the first guide wire, the correction axis of insertion of the second guide wire being selected between an axis that is angled at a fixed angle relative to the initial axis and an axis that is parallel to the initial axis.

2. The method of claim 1 , wherein the correction channel extends through the device along one of a first axis angled relative to the initial axis, a second axis angled relative to the initial axis where the second axis is on a side of the initial axis opposite the first axis, and a third axis parallel to the initial axis.

3. The method of claim 2 , wherein the desired corrected placement of the first guide wire is determined based on an image of the bone into which the first guide wire has been inserted, the method further comprising inserting a third guide wire through the device along another one of the first, second and third axes to further correct a placement of the first guide wire.

4. The method of claim 1 , wherein the device further includes a handle portion extending from a proximal end thereof, the handle portion includes a pair of wings extending laterally from the proximal end at an angle relative to a longitudinal axis of a body of the device, each of the wings extending from sides of the body on opposite sides of the initial channel.

5. The method of claim 1 , further comprising:
imaging the bone to confirm a desired correct placement of the second guide wire.

6. The method of claim 1 , further comprising:
determining a desired corrected placement of the second guide wire;
inserting the second guide wire into the initial channel of the device;
sliding the device along the second guide wire until the distal end thereof abuts the surface of the bone; and
inserting a third guide wire through the correction channel of the device in accord with the desired corrected placement of the second guide wire.

7. The method of claim 6 , further comprising:
imaging the bone to confirm a desired correct placement of the third guide wire.

8. The method of claim 1 , wherein a diameter of the correction channel is slightly greater than a diameter of the second guide wire.

9. The method of claim 1 , wherein the correction channel tapers from a proximal end to the distal end of the device so that the second guide wire is receivable therein at a desired angle relative to the initial axis, within a permitted range of angulations.

10. The method of claim 9 , wherein the device includes markings showing angles relative to the axis of the initial channel within the permitted range of angulations.

11. The method of claim 1 , wherein the correction channel tapers from a proximal end to the distal end of the device so that a longitudinally extending slider is receivable therein at a desired angle relative to the initial axis, within a permitted range of angulations, the slider pivotably coupled to the distal end of the device and including an alignment channel extending longitudinally therethrough, the alignment channel sized and shaped to receive the second guide wire therein.

12. The method of claim 11 , further comprising moving the slider along the correction channel so that an axis of the alignment channel of the slider aligns with the desired corrected placement of the first guide wire.

13. The method of claim 11 , wherein the slider includes an engaging feature engageable with a plurality of correspondingly sized and shaped engaging features of an opening groove at a proximal end of the correction channel.

14. The method of claim 13 , further comprising aligning the engaging feature of the slider with one of the engaging features of the groove to fix the slider at the desired angle of insertion.

15. The method of claim 1 , wherein an axis of the correction channel is angled relative to the initial axis at an angle ranging from between 5 and 10 degrees.

16. The method of claim 1 , wherein a length of the device is selected so that, when the device is slid along the first guide wire until the distal end thereof abuts the surface of the bone, the proximal end of the device extends proximally to be accessible to a user.

17. A method for correcting a guide wire placement in a bone, comprising:
inserting a first guide wire into a bone;
determining a desired corrected placement of the first guide wire;
inserting the first guide wire into an initial channel of a device along an initial axis;
sliding the device along the first guide wire until a distal end thereof abuts a surface of the bone;
inserting a second guide wire through a correction channel of the device, the correction channel being oriented, when the device is received over the first guide wire, to direct the second guide wire into the bone along a correction axis of insertion corresponding to the desired corrected placement of the first guide wire, the correction axis of insertion of the second guide wire being selected between an axis that is angled relative to the initial axis and an axis that is parallel to the initial axis; and
moving a slider so that an opening of the slider is aligned with a desired angle of insertion of the second guide wire through the correction channel, the slider slidably housed within a correspondingly sized and shaped groove extending laterally through the device in communication with the correction channel.

18. The method of claim 17 , wherein the slider includes an engaging feature engageable with a plurality of correspondingly sized and shaped engaging features of the groove.

19. The method of claim 18 , further comprising aligning the engaging feature of the slider with one of the engaging features of the groove to fix the slider at the desired angle of insertion.

20. A method for correcting a guide wire placement in a bone, comprising:
inserting a first guide wire into a bone;
determining a desired corrected placement of the first guide wire;
inserting the first guide wire into an initial channel of a device along an initial axis, the device containing a plurality of guide wire markings and a correction channel tapering from a proximal end to a distal end of the device so that a second guide wire is receivable therein at a desired angle relative to the initial axis, within a permitted range of angulations;
sliding the device along the first guide wire until a distal end thereof abuts a surface of the bone;
moving a slider so that an opening of the slider is aligned with a desired angle of insertion of the second guide wire through the correction channel, the slider slidably housed within a correspondingly sized and shaped groove extending laterally through the device in communication with the correction channel; and
inserting the second guide wire through the device in alignment with a first one of the guide wire markings corresponding to the desired corrected placement of the first guide wire.
