Abstract

Disclosed is a surgical navigation system for tracking an instrument relative to a patient. The system can track a portion of the patient, an instrument, and/or both relative to image data, a coordinate system, an atlas, a morphed atlas, or combinations thereof. The system can include a tracking device on the instrument to provide six degree of freedom information regarding the location of the instrument.

First claim

What is claimed is:

1 . A trackable instrument assembly, comprising:
a first elongated guide defining a first bore extending from a first proximal end to a first distal end; a second elongated sleeve defining a second bore extending from a second proximal end to a second distal end, the second elongated sleeve configured to be positionable in the first bore; at least one tracking device attached to the second elongated sleeve; and a tool extending from a third proximal end to a third distal end, the tool configured to be positionable in the second bore; wherein the at least one tracking device is configured to be used to track a selected portion of the tool.

2 . The trackable instrument assembly of claim 1 , wherein the at least one tracking device is attached to the second distal end of the second elongated sleeve.

3 . The trackable instrument assembly of claim 2 , wherein the selected portion of the tool is the third distal end of the tool.

4 . The trackable instrument assembly of claim 3 , wherein the tool is a drill bit having a drill tip at the third distal end.

5 . The trackable instrument assembly of claim 4 , wherein the drill bit includes a stop member for interacting with the second proximal end of the second elongated sleeve as the drill tip extends beyond the first distal end of the first elongated guide.

6 . The trackable instrument assembly of claim 1 , further comprising a spring configured to be positionable in the first bore to assist in tracking a selected portion of the tool.

7 . The trackable instrument assembly of claim 6 , wherein the spring is configured to be compressed a selected distance during operation of the tool.

8 . The trackable instrument assembly of claim 4 , wherein the drill bit includes a tool engaging portion at the third proximal end wherein the drill bit is configured to rotate relative to the second elongated sleeve.

9 . The trackable instrument assembly of claim 1 , wherein the first elongated guide further includes a handle.

10 . The trackable instrument assembly of claim 1 , wherein the at least one tracking device is a tracking coil positioned relative to the second distal end of the second elongated sleeve.

11 . The trackable instrument assembly of claim 1 , wherein the at least one tracking device includes a first tracking device and a second tracking device.

12 . The trackable instrument assembly of claim 1 , wherein the tool is selected from a drill bit or an awl.

13 . The trackable instrument assembly of claim 1 , wherein the trackable instrument assembly is formed of a substantially non-magnetic material.

14 . The trackable instrument assembly of claim 1 , wherein the first elongated guide defines an elongated slot configured to accommodate a connection to the at least one tracking device.

15 . A trackable instrument assembly, comprising:
a first external tube having a handle and defining a first bore extending from a first proximal end with a first distal end; a second elongated sleeve defining a second bore extending from a second proximal end to a second distal end, the second elongated sleeve configured to be movably positionable in the first bore; at least one tracking sensor attached to the second distal end of the second elongated sleeve; and a drill bit extending from a tool engaging proximal end to a drill bit tip distal end, the drill bit configured to be rotationally positioned in the second bore; wherein the at least one tracking sensor is configured to track the distal drill bit tip of the drill bit.

16 . The trackable instrument assembly of claim 15 , wherein at least one tracking sensor is a tracking coil wrapped around the second distal end of the second elongated sleeve.

17 . The trackable instrument assembly of claim 15 , wherein the at least one tracking sensor includes two spaced-apart tracking sensors positioned on the second elongated sleeve such that the distance and orientation between the two tracking sensors remains substantially constant.

18 . The trackable instrument assembly of claim 15 , further comprising a spring configured to be positionable in the first bore to assist in tracking the drill bit.

19 . A trackable instrument assembly, comprising:
an external tube having a handle and a defining a cannula extending from a first tube end to a second tube end; a sleeve defining a sleeve bore extending from a first sleeve end to a second sleeve end, the sleeve configured to be positioned in the cannula; at least one tracking sensor attached to the sleeve; and a tool extending from a first tool end to a second tool end, the tool configured to be movably positioned in the sleeve bore; wherein the at least one tracking sensor is configured to be used to track a selected portion of the tool.

20 . The trackable instrument assembly of claim 19 , wherein the at least one tracking sensor is operated either substantially wired or wireless.
