Abstract

An endoscope tracking system includes an endoscope, at least one endoscope tracking transmitter carried by the endoscope, a plurality of anatomy mapping transmitters, a receiver communicating with the at least one endoscope tracking transmitter and the anatomy mapping transmitters and a processor communicating with the receiver. The processor is adapted to generate an anatomical map based on input from the anatomy mapping transmitters and an endoscope tracking image based on input from the at least one endoscope tracking transmitter and superimpose the endoscope tracking image on the anatomical map.

Claims

1. An endoscope tracking system, comprising:

an endoscope;

at least one endoscope tracking transmitter carried by said endoscope;

a plurality of anatomy mapping transmitters;

a receiver communicating with said at least one endoscope tracking transmitter and said anatomy mapping transmitters;

a processor communicating with said receiver; and

wherein said processor is adapted to generate an anatomical map based on input from said anatomy mapping transmitters and an endoscope tracking image based on input from said at least one endoscope tracking transmitter and superimpose said endoscope tracking image on said anatomical map.

2. The system of claim 1 wherein said endoscope comprises an endoscope handle and an elongated, flexible endoscope shaft extending from said endoscope handle and wherein said at least one endoscope tracking transmitter is provided on said endoscope shaft.

3. The system of claim 1 further comprising a monitor having a monitor screen and wherein said processor is adapted to display said anatomical map and said endoscope tracking image on said monitor screen of said monitor.

4. The system of claim 1 further comprising an endoscope insertion sensor communicating with said processor and a terminal endoscope tracking transmitter provided on said endoscope and communicating with said processor.

5. The system of claim 1 wherein said at least one endoscope tracking transmitter comprises a plurality of endoscope tracking transmitters carried by said endoscope in spaced-apart relationship with respect to each other.

6. An endoscope tracking method, comprising:

providing an endoscope;

providing at least one endoscope tracking transmitter on said endoscope;

providing a plurality of anatomy mapping transmitters;

placing said anatomy mapping transmitters in spatial relationship with respect to each other on a patient;

generating an anatomical map of said patient using input from said anatomy mapping transmitters;

generating an endoscope tracking image using input from said at least one endoscope tracking transmitter;

inserting said endoscope into said patient; and

superimposing said endoscope tracking image on said anatomical map.

7. The method of claim 6 wherein said providing an endoscope comprises providing an endoscope having an endoscope handle and an elongated, flexible endoscope shaft extending from said endoscope handle, and wherein said providing at least one endoscope tracking transmitter on said endoscope comprises providing a plurality of spaced-apart endoscope tracking transmitters on said endoscope shaft.

8. The method of claim 6 wherein said generating an anatomical map of said patient comprises generating an anatomical map of an abdominal region of said patient and wherein said inserting said endoscope into said patient comprises inserting said endoscope into a large intestine of said patient.

9. The method of claim 6 further comprising providing calculating a length of insertion of said endoscope into said patient.

10. The method of claim 9 wherein said calculating a length of insertion of said endoscope into said patient comprises providing a terminal endoscope tracking transmitter on said endoscope, providing an endoscope insertion sensor on said patient and calculating a distance between said terminal endoscope tracking transmitter and said endoscope insertion sensor.
