Abstract

A method and system for nerve identification, monitoring, location marking, and location recognition system used during laparoscopic surgery.

Claims (59)

1. A nerve monitoring system comprising:

an optical element to connect to a camera;

at least one recording probe and at least one exploratory probe;

processors and memories, wherein the processors are coupled to the memories to perform operations comprising:

in response to communications from the at least one recording probe, indicating proximity of the at least one exploratory probe to a nerve based on a strength of an electrical signal sensed by the at least one recording probe;

in response to indicating the proximity of the at least one exploratory probe to the nerve, generating and displaying a digital marker representing a location of the nerve within a displayed visual field that is generated while the optical element is at a first physical location;

in response to the optical element being repositioned from a second physical location back to the first physical location, recognizing an image that was present within the displayed visual field when the optical element was initially at the first physical location;

in response to recognizing the image that was present on a monitor when the optical element was initially at the first physical location, redisplaying the digital marker within the displayed visual field.

2. The nerve monitoring system of claim 1 , wherein the processors are coupled to the memories to perform operations comprising:

in response to a first user input, generating and displaying the digital marker representing the location of the nerve within the displayed visual field that is generated while the optical element is at the first physical location.

3. The nerve monitoring system of claim 2 , wherein the processors are coupled to the memories to perform operations comprising:

in response to a second user input, redisplaying the digital marker within the displayed visual field.

4. The nerve monitoring system of claim 2 , wherein the nerve is not visible within the displayed visual field generated while the optical element is at the first physical location.

5. The nerve monitoring system of claim 1 , wherein the processors are coupled to the memories to perform operations comprising:

in response to a user input, returning the optical element to the first physical location.

6. The nerve monitoring system of claim 5 , wherein the processors are coupled to the memories to perform operations comprising:

in response to indicating the proximity of the at least one exploratory probe to the nerve, generating and displaying the digital marker representing the location of the nerve within the displayed visual field generated while the optical element is at the first physical location and has a first magnification;

in response to the user input, returning the optical element to the first physical location at the first magnification.

7. The nerve monitoring system of claim 6 , wherein the processors are coupled to the memories to perform operations comprising:

in response to indicating the proximity of the at least one exploratory probe to the nerve, generating and displaying the digital marker representing the location of the nerve within the displayed visual field generated while the optical element is at the first physical location and has a first orientation;

in response to the user input, returning the optical element to the first physical location at the first orientation.

8. The nerve monitoring system of claim 6 , wherein the processors are coupled to the memories to perform operations comprising:

in response to the user input, redisplaying the digital marker within the displayed visual field.

9. The nerve monitoring system of claim 1 , wherein

the electrical signal sensed by the at least one recording probe includes an electrical potential or a derivation thereof.

10. A nerve monitoring system comprising:

12. The nerve monitoring system of claim 10 , wherein the nerve is not visible within the displayed visual field generated while the optical element is at the first physical location.

13. The nerve monitoring system of claim 10 , wherein the processors are to couple to the memories to perform operations comprising:

introducing an additional electrical signal to tissue via the at least one exploratory probe to create an electrical potential received by the at least one recording probe;

analyzing and displaying the electrical potential;

evaluating the electrical potential to determine the location of the nerve;

wherein the communications from the at least one recording probe include the electrical potential or a derivation thereof.

14. A machine-readable media having stored thereon data, which if used by machines, cause the machines to perform operations comprising:

in response to communications from at least one recording probe, indicating proximity of at least one exploratory probe to a nerve based on a strength of an electrical signal sensed by the at least one recording probe;

in response to indicating the proximity of the at least one exploratory probe to the nerve, generating and displaying a digital marker representing a location of the nerve within a displayed visual field that is generated while an optical element is at a first physical location;

in response to the optical element being repositioned from a second physical location back to the first physical location, recognizing an image that was present within the displayed visual field when the optical element was initially at the first physical location;

in response to recognizing the image that was present on a monitor when the optical element was initially at the first physical location, redisplaying the digital marker within the displayed visual field.

15. The media of claim 14 , the operations further comprising:

in response to a first user input, generating and displaying the digital marker representing the location of the nerve within the displayed visual field that is generated while the optical element is at the first physical location.

16. The media of claim 15 , the operations further comprising:

in response to a second user input, redisplaying the digital marker within the displayed visual field.

17. The media of claim 14 , the operations further comprising:

in response to a user input, returning the optical element to the first physical location.

18. The media of claim 17 , the operations further comprising:

in response to indicating the proximity of the at least one exploratory probe to the nerve, generating and displaying the digital marker representing the location of the nerve within the displayed visual field generated while the optical element is at the first physical location and has a first magnification;

in response to the user input, returning the optical element to the first physical location at the first magnification.

19. The media of claim 18 , the operations further comprising:

in response to indicating the proximity of the at least one exploratory probe to the nerve, generating and displaying the digital marker representing the location of the nerve within the displayed visual field generated while the optical element is at the first physical location and has a first orientation;
