Abstract

There is provided herein a circuit board assembly for a tip section of a multi-camera endoscope comprising a camera circuit board configured to carry at least one front-pointing camera and at least one side-pointing camera, a flexible illuminator circuit board comprising at least one foldable panel and configured to carry at least one front illuminator for essentially illuminating the field of view (FOV) of the front-pointing camera and at least one side illuminator for essentially illuminating the FOV of the side-pointing camera.

Claims

1. An electronic assembly for a tip section of a multi-camera endoscope, the assembly comprising:

a front-pointing camera facing a first direction;

a first side-pointing camera facing a second direction;

a second side-pointing camera facing a third direction, wherein the second direction is opposite the third direction and wherein the second and third directions are substantially perpendicular to the first direction;

a camera circuit board configured to communicate with the front-pointing camera, first side-pointing camera, and second side-pointing camera; and

a flexible illuminator circuit board comprising

a first section comprising a first plurality of flexible panels;

a second section comprising a second plurality of flexible panels;

a third section that is attached to the first and second sections, wherein, in a first configuration, the first section, second section and third section define a first plane;

a first illuminator mounted on the third section;

a second illuminator mounted on one of said first plurality of flexible panels;

a third illuminator mounted on one of said second plurality of flexible panels wherein, upon said flexible illuminator circuit board being folded into a second, operative configuration, the first illuminator is positioned adjacent to the front-pointing camera and defines a second plane orthogonal to the first plane, the second illuminator is positioned adjacent to the first side-pointing camera and defines a third plane orthogonal to the first plane, and the third illuminator is positioned adjacent to the second side-pointing camera and defines a fourth plane orthogonal to the first plane, and wherein said second, third and fourth planes are different.

2. The electronic assembly according to claim 1, further comprising one or more circuit board holders configured to support said flexible illuminator circuit board, said camera circuit board or both.

3. The electronic assembly according to claim 2, wherein said circuit board holder comprises at least one niche configured to accommodate at least one of said illuminators or at least one of said cameras.

4. The electronic assembly according to claim 1, wherein said camera circuit board is a foldable camera circuit board.

5. The electronic assembly according to claim 1, wherein said camera circuit board is configured to carry the front-pointing camera and the two side-pointing cameras.

6. A tip section for a multi-camera endoscope, the tip section comprising the electronic assembly of claim 1 and a fluid channeling component.

7. The tip section according to claim 6, wherein said fluid channeling component comprises:

at least one front fluid injector configured for cleaning said at least one front-pointing camera or said at least one of front illuminator;

at least one side fluid injector configured for cleaning said at least one side-pointing camera or said at least one of side illuminator; and

a front working channel configured for insertion of a medical tool.

8. The tip section according to claim 7, wherein said front and side fluid injectors are connected to a same fluid supply channel.

9. The tip section according to claim 6, wherein said at least one said first illuminator, said second illuminator, and said third illuminator comprises a discrete illuminator.

10. The tip section according to claim 9, wherein said discrete illuminator comprises a light-emitting diode (LED).

11. The tip section according to claim 6, wherein at least one of said first illuminator, said second illuminator, and said third illuminator is configured to emit white light.

12. The tip section according to claim 6, wherein at least one of said first illuminator, said second illuminator, and said third illuminator is configured to emit ultraviolet light.

13. The tip section according to claim 6, wherein at least one of said first illuminator, said second illuminator, and said third illuminator is configured to emit infrared light.

14. The tip section according to claim 6, wherein at least one of said first illuminator, said second illuminator, and said third illuminator is configured to emit near-infrared light.

15. The tip section according to claim 6, wherein said first illuminator, said second illuminator, and said third illuminator are configured to emit light in different wavelengths.

16. The tip section according to claim 6, wherein said front-pointing camera and said side-pointing camera independently comprise a Charge Coupled Device (CCD) or a Complementary Metal Oxide Semiconductor (CMOS) image sensor.

17. The tip section according to claim 6, wherein said endoscope is a colonoscope.

18. The tip section according to claim 6, wherein fields of view of said front-pointing camera and side-pointing camera are at least partially overlapping.

19. The tip section according to claim 6, wherein said at least one of said front and side pointing cameras comprises a lens assembly providing a field of view of at least 90 degrees.

20. The tip section according to claim 6, wherein said at least one of said front and side pointing cameras comprises a lens assembly providing a field of view of at least 120 degrees.

21. The tip section according to claim 6, wherein said at least one of said front and side pointing cameras comprises a lens assembly providing a focal length of approximately 3-100 millimeters.
