Flexible electronic circuit board for a multi-camera endoscope
First Claim
1. A tip section of a multi-camera endoscope, the tip section comprising:
- a forward looking camera positioned on a distal end surface of the tip section, a first side camera positioned on a first side surface of the tip section, and a second side camera positioned on a second side surface of the tip section, wherein each of the forward looking, first side, and second side camera has an associated field of view (FOV);
three front illuminators positioned on the distal end surface of the tip section, one or more first side illuminators positioned on the first side surface of the tip section, and one or more second side illuminators positioned on the second side surface of the tip section;
a working channel extending through the tip section and exiting through a working channel opening on the distal end surface of the tip section;
a fluid channel extending through the tip section and exiting through a fluid channel opening on the distal end surface of the tip section;
a nozzle in fluid communication with a channel, wherein the channel extends through the tip section and wherein the nozzle is positioned on the distal end surface of the tip section; and
a folded flexible electronic circuit board positioned within, and enclosed inside, the distal end surface, first side surface, and second side surface of the tip section, the folded flexible electronic circuit board comprising;
a front camera surface configured to carry the forward looking camera;
a first side camera surface configured to carry the first side looking camera;
a second side camera surface configured to carry the second side looking camera;
a first illuminator surface configured to carry a first of the three front illuminators, a second illuminator surface configured to carry a second of the three front illuminators, and a third illuminator surface configured to carry a third of the three front illuminators, wherein the first illuminator surface, the second illuminator surface, and the third illuminator surface form an arc shape and wherein the forward looking camera is positioned within, and supported by, said arc shape;
one or more side illuminator surfaces configured to carry the one or more first side illuminators to illuminate the FOV of the first side looking camera; and
one or more side illuminator surfaces configured to carry the one or more second side illuminators to illuminate the FOV of the second side looking camera.
