Abstract

The invention relates to a surgical instrument capable of applying an electrostimulation to a neural structure. The surgical instrument also has a tracking system associated therewith to provide navigational tracking during a surgical procedure.

Claims

33
AMENDED CLAIMS received by the International Bureau on 22 December 2008 (22.12.08)
an energy source operable with the instrument and designed to provide electrical energy to the conductive member for application of electrostimulation to a neural structure when the neural structure is in contact with the portion of the conductive member and electrical energy is provided to the conductive member; and
a tracking system associated with the instrument and operative to provide information regarding a position of the instrument.
20. The surgical tool assembly of claim 19 wherein the energy source is a battery.
21. The surgical tool assembly of claim 20 wherein the battery is housed within the handle.
22. The surgical tool assembly of claim 19 wherein the insulating sheath includes a non-conductive coating on the conductive member.
23. The surgical tool assembly of claim 19 wherein the instrument is one of a probe, a retractor, a screwdriver, and a tap.
24. The surgical tool assembly of claim 19 wherein the instrument is capable of applying bipolar or unipolar electrostimulation to the neural structure.
25. The surgical tool assembly of claim 19 wherein the tracking system includes active, passive, or a combination of active and passive tracking elements.
26. A neuromonitoring instrument capable of applying electrostimuation to a neural structure, the instrument comprising:
a handle and a stylet extending from a distal end of the handle; and
a navigational sensor associated with at least one of the handle and the stylet, the navigation sensor operative to provide feedback regarding a position of the instrument. 34
27. The neuromonitoring probe of claim 26 further comprising a cannula of insulating material extending from the distal end of the handle and wherein the stylet is disposed within a lumen of the cannula.
28. The neuromonitoring probe of claim 27 wherein the navigational sensor is secured to an outer surface of the cannula.
29. The neuromonitoring probe of claim 28 wherein the navigational sensor is a reflector.
30. The neuromonitoring probe of claim 26 wherein the handle houses an energy source that provides energy to the stylet for the application of electrostimulation to a neural structure.
31. The neuromonitoring probe of claim 30 wherein the energy source is a battery.
32. The neuromonitoring probe of claim 26 wherein the stylet includes a pointed distal end capable of forming a hole in a pedicle.
