Abstract

There is provided herein, an electronic circuit board assembly for a tip section of a multiple viewing elements endoscope, the assembly including a base board configured to carry a first metal frame to support a front looking viewing element and a second metal frame to support a side looking viewing element; and a flexible illumination circuit board comprising a front foldable panel configured to carry three sets of front illuminators for essentially illuminating the field of view (FOV) of the front looking viewing element, and a side foldable panel configured to carry a set of side illuminators for essentially illuminating the field of view (FOV) of the side looking viewing element.

First claim

We claim:

1. An electronic circuit board assembly for a medical device, the assembly comprising:

a first frame coupled to the first side of the first base circuit board and configured to receive a front image sensor including a second circuit board, wherein the first frame is positioned at one end of the first base circuit board; and
a second base circuit board including a third side and a fourth side, wherein the third side is positioned on an opposite side of the second base circuit board from the fourth side; and wherein the second circuit board is coupled to the fourth side of the second base circuit board;
wherein the second circuit board is coupled to the first frame and the second side of the first base circuit board;
wherein the second circuit board extends through an opening in the second base circuit board.

2. The electronic circuit board assembly of claim 1 , wherein the second circuit board is folded into a “U” shape.

3. The electronic circuit board assembly of claim 1 , wherein the second circuit board extends through an opening in the first base circuit board.

4. The electronic circuit board assembly of claim 1 , wherein the second circuit board extends across three sides of the first frame.

5. The electronic circuit board assembly of claim 1 , wherein the first frame is coupled to the fourth side of the second base circuit board.

6. The electronic circuit board assembly of claim 1 , further comprising a second frame configured to receive a side image sensor including a third circuit board, wherein the second frame is positioned adjacent to the first frame.

7. The electronic circuit board assembly of claim 6 , wherein the third circuit board is coupled to the second side of the first base circuit board.

8. The electronic circuit board assembly of claim 1 , further comprising a first lens assembly coupled to the first frame.

9. The electronic circuit board assembly of claim 1 , further comprising:
a first illuminator circuit board comprising a first panel and a first illuminator, wherein the first illuminator circuit board is mounted on the first base circuit board within at least one first groove of the first base circuit board; and
a second illuminator circuit board comprising a second panel and a second illuminator, wherein the second illuminator circuit board is mounted on the first base circuit board within at least one second groove of the first base circuit board; wherein the first illuminator faces a direction transverse to the second illuminator.

10. The electronic circuit board assembly of claim 1 , wherein the front image sensor includes a piece of glass.

11. The electronic circuit board assembly of claim 1 , wherein the second circuit board includes a first plurality of connector pins and a second plurality of connector pins, wherein the first plurality of connector pins are at an opposite end of the second circuit board from the second plurality of connector pins.

12. The electronic circuit board assembly of claim 11 , wherein the first plurality of connector pins and the second plurality of connector pins are substantially parallel to the first base circuit board.

13. The electronic circuit board assembly of claim 1 , further comprising:
a metal supporting frame positioned between the first base circuit board and the second base circuit board and configured to act as a heat sink.

14. The electronic circuit board assembly of claim 1 , wherein the front image sensor includes one of a charge coupled device (CCD) and a complementary metal oxide semiconductor (CMOS) image sensor.

15. An electronic circuit board assembly for a medical device, the assembly comprising:
a first base circuit board;
