Abstract

The present invention regards a guiding tool for neurosurgery. The guiding tool comprises subunits and a holder. The subunits are arranged in the holder so that holes for guiding a probe are created in the interface between said subunits, which allows easy release of the probe. The invention further regards a system for guiding neurosurgery probes.

Claims

1. A guiding tool for guiding a deep brain stimulation probe into tissue, the guiding tool comprising:

a plurality of subunits, each of the plurality of subunits having an indentation along an edge; and

a holder configured to hold together the plurality of subunits, wherein the plurality of subunits are configured to be mounted in the holder to form a guiding tool including a plurality of holes, the plurality of holes including a central hole and two or more holes spaced around the central hole such that the central hole is generally in a center of the plurality of holes, each of the plurality of holes being formed around a complete perimeter by only two of the indentations, wherein the tool is configured to receive a distal end of the probe through at least one hole of the plurality of holes to guide the distal end of the probe into the tissue to implant the distal end of the probe while the probe is disposed within the at least one hole, and wherein the plurality of subunits are configured to be dismantled from the deep brain stimulation probe while the distal end of the deep brain stimulation probe is implanted into the tissue and while the probe is disposed within the at least one hole without drawing the deep brain stimulation probe through the at least one hole of the plurality of holes to remove the probe from within the at least one hole.

2. The guiding tool of claim 1, wherein the number of the plurality of subunits is less than a number of the plurality of holes.

3. The guiding tool of claim 1, wherein the number of the plurality of holes is five.

4. The guiding tool of claim 1, wherein the number of the plurality of subunits is three and the number of the plurality of holes is five.

5. The guiding tool of claim 1, wherein the plurality of holes includes a first row including two of the plurality of holes, a second row including one of the plurality of holes, and a third row including two of the plurality of holes.

6. the guiding tool of claim 1 further comprising at least one deep brain stimulation probe configured to be drawn though at least one the plurality of holes.

7. The guiding tool of claim 1, wherein each of the plurality of subunits has a different shape.

11. The guiding tool of claim 6, wherein the at least one deep brain stimulation probe is a chronic deep brain stimulation probe.

12. The guiding tool of claim 1, wherein the holder and the plurality of subunits are mounted together using an attachment means, wherein the attachment means is configured to apply a pressure between the holder and the plurality of subunits to hold the holder and the plurality of subunits together.

13. The guiding tool of claim 1, wherein the plurality of subunits are configured such that there is only one possible way to fit the plurality of subunits in the holder to form the guiding tool.

14. The guiding tool of claim 1, wherein the plurality of subunits are configured to be removed from the deep brain stimulation probe without having to slide the deep brain stimulation probe through the guiding tool.

15. The guiding tool of claim 1, wherein the plurality of subunits are configured to allow a diameter of part of the deep brain stimulation probe to be larger than a diameter of one of the plurality of holes.

8. A guiding tool for guiding a deep brain stimulation probe into tissue, the tool comprising:

a plurality of subunits, each of the plurality of subunits having an indentation along an edge; and

a holder configured to hold together the plurality of subunits, wherein the plurality of subunits are configured to be mounted in a holder to form a guiding tool including a plurality of holes, the plurality of holes including a central hole and two or more holes spaced around the central hole such that the central hole is generally in a center of the plurality of holes, a number of the plurality of subunits being more than a number of the plurality of holes, wherein the tool is configured to receive a distal end of the probe through at least one hole of the plurality of holes to guide the distal end of the probe into the tissue to implant the distal end of the probe while the probe is disposed within the at least one hole, and wherein the plurality of subunits are configured to be dismantled from the deep brain stimulation probe while the distal end of the deep brain stimulation probe is implanted into the tissue and while the probe is disposed within the at least one hole without drawing the deep brain stimulation probe through the at least one hole of the plurality of holes to remove the probe from within the at least one hole.

9. The guiding tool of claim 8, wherein the number of the plurality of subunits is six and the number of the plurality of holes is five.

10. The guiding tool of claim 8, wherein removing one of the plurality of subunits from a remainder of the plurality of subunits opens only one of the plurality of holes.

16. The guiding tool of claim 8, wherein the holder and the plurality of subunits are mounted together using an attachment means, wherein the attachment means is configured to apply a pressure between the holder and the plurality of subunits to hold the holder and the plurality of subunits together.
