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:

at least one panel protruding from an edge portion of the first strip, wherein the at least one panel is coplanar with the first strip in the unfolded configuration of the printed circuit board, and wherein the at least one panel extends transverse to the first strip in the folded configuration of the printed circuit board, and
a second strip connected to the second arm, wherein the second strip is coplanar with the second arm in the unfolded configuration of the printed circuit board, wherein the second strip extends transverse to the second arm in the folded configuration of the printed circuit board, and wherein the second strip extends parallel to the first strip;

at least one illuminator coupled to at least one of the U-shaped carrier and the at least one panel;
at least one image sensor received between opposing edges of the printed circuit board with the printed circuit board in the folded configuration; and
a heat sink configured to receive the printed circuit board.

2. The assembly of claim 1 , wherein the at least one illuminator is coupled to the at least one panel.

3. The assembly of claim 1 , wherein the at least one illuminator includes a plurality of illuminators, wherein one of the plurality of illuminators is coupled to the U-shaped carrier and another one of the plurality of illuminators is coupled to the at least one panel.

4. The assembly of claim 1 , wherein the at least one panel includes a plurality of panels protruding from the edge portion of the first strip.

5. The assembly of claim 1 , wherein the at least one panel is at least one first panel, and wherein the printed circuit board includes at least one second panel protruding from an edge portion of the second strip.

6. The assembly of claim 1 , further comprising a plurality of illuminators coupled to the U-shaped carrier.

7. The assembly of claim 6 , wherein the at least one panel is a plurality of first panels protruding from the edge portion of the first strip, and the printed circuit board includes a plurality of second panels protruding from an edge portion of the second strip, and wherein the at least one illuminator is at least one front illuminator, and the printed circuit board includes a plurality of side illuminators coupled to the plurality of first and second panels.

8. The assembly of claim 1 , wherein the heat sink includes at least one recess configured to receive the at least one panel.

9. An assembly for a tip section of an endoscope, the assembly comprising:
a printed circuit board configured to move from an unfolded configuration to a folded configuration, the printed circuit board comprising:
