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.
Claims29
-36. (canceled)
A surgical tool capable of applying electrostimulation comprising:
- an instrument having a handle portion and a body member extending from the handle portion, the body member having an electrically conductive portion connected to an energy source and capable of applying electrostimulation energy provided by the energy source;
- and
- a tracking system associated with the instrument and operative to provide information regarding a position of the instrument on a display, the tracking system being configured to detect neurological information based on electrostimulation energy applied by the instrument and superimpose the neurological information on the instrument position on the display.
A surgical tool assembly comprising:
- an instrument having a handle, an insulating sheath, and a conductive member connected to the handle and internal to the insulating sheath, wherein a portion of the conductive member projects distally from the insulating sheath;
- 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 on a display, the tracking system being configured to detect neurological information based on the electrostimulation energy applied by the instrument and superimpose the neurological information on the instrument position information on the display.
A neuromonitoring system capable of applying electrostimuation energy to a neural structure, the system comprising:
- an 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, and
- a tracking system associated with the instrument and operative to provide information regarding a position of the instrument on a display, the tracking system being configured to detect neurological information based on the electrostimulation energy applied by the instrument and superimpose the neurological information on the instrument position information on the display.
The neuromonitoring probe of claim 63 wherein the energy source is a battery.
