Abstract

A digitizer pointer is provided as part of a system for correcting a curvature or deformity in a patient'"'"'s spine based on the digitized locations of implanted screws and tracking the placement of the rod as it is placed in a minimally invasive fashion. The digitizer pointer is includes an offset adjustment feature, a swivel feature, and a translation feature.

Claims

1. A device for positioning an infrared tracking member relative to implanted surgical implants, comprising:

a first elongated element comprising a proximal portion of the device, the first elongated element comprising a proximal end and a distal end, the proximal end comprising an attachment element for attaching the infrared tracking member to the device, the distal end comprising a recess;

a second elongated element linearly aligned with the first elongated element and comprising a middle portion of the device, the second elongated element having a proximal elongated shaft segment and a distal elongated shaft segment and a guide pin extending laterally away from the second elongated element, the proximal elongated shaft segment having a proximal end comprising a cavity formed within the proximal end and a retention element, the retention element configured to engage the recess, the distal elongated shaft segment having a distal end comprising an attachment feature configured to engage a surgical implant;

wherein the first elongated element is independently rotatable of the second elongated element; and

a third elongated element linearly aligned with the second elongated element and comprising a distal portion of the device, wherein the third elongated element has a track housing configured to receive the guide pin on the second elongated element, and wherein the second and third elongated elements are slideably associated with one another through movement of the guide pin in the track housing.

2. The device of claim 1, wherein the attachment element is a threaded post.

3. The device of claim 1, wherein the distal end of the first elongated element further comprises a smooth post.

4. The device of claim 3, wherein the cavity is configured to receive the smooth post.

5. The device of claim 4, wherein the retention element is configured to prevent the smooth post from ejecting from the cavity.

6. The device of claim 1, wherein the second elongated element is translationally associated with the third elongated element.

7. The device of claim 1, wherein the third elongated element comprises a tubular member including a central lumen extending longitudinally therethrough.

8. The device of claim 7, wherein the second elongated element is slideably received within the central lumen.

9. The device of claim 1, wherein the distal end of the third elongated element comprises a shaped end configured to engage a surgical implant.

10. A device for positioning an infrared tracking member relative to implanted surgical implants, comprising:

a first elongated element comprising a proximal portion of the device, the first elongated element comprising a proximal end, a distal end, a helical slot, a plurality of offset depth slots located around the helical slot, and a helical pin extending laterally away from the first elongated element, the proximal end includes an inner piston comprising an attachment element for attaching the infrared tracking member to the device, wherein the inner piston comprises a slot configured to receive the helical pin, wherein the plurality of offset depth slots are configured to receive the helical pin, wherein the proximal end and the inner piston are slideably associated with one another through movement of the helical pin in the helical slot, the distal end comprising a recess;

a second elongated element linearly aligned with the first elongated element and comprising a middle portion of the device, the second elongated element having a proximal elongated shaft segment and a distal elongated shaft segment and a guide pin extending laterally away from the second elongated element, the proximal elongated shaft segment having a proximal end comprising a cavity formed within the proximal end and a retention element, the retention element configured to engage the recess, the distal elongated shaft segment having a distal end comprising an attachment feature configured to engage a surgical implant;

wherein the first elongated element is independently rotatable of the second elongated element; and

a third elongated element linearly aligned with the second elongated element and comprising a distal portion of the device, wherein the third elongated element has a track housing configured to receive the guide pin on the second elongated element, and wherein the second and third elongated elements are slideably associated with one another through movement of the guide pin in the track housing.

11. The device of claim 10, wherein the third elongated element further comprises a tubular member including a central lumen extending longitudinally therethrough.

12. The device of claim 11, wherein the second elongated element is slideably received within the central lumen.

13. The device of claim 10, wherein the first elongated element is independently rotatable relative to the second elongated element.

14. The device of claim 10, wherein the first elongated element has a distal end including a smooth post extending distally therefrom.

15. The device of claim 14, wherein the second elongated element has a proximal end including a cavity formed within the proximal end, the cavity configured to receive the smooth post.

16. The device of claim 10, the distal end of the third elongated element comprises a shaped end configured to engage a surgical implant.
