There is provided herein a tip section of a multi-viewing element endoscope, the tip section comprising: two or more side-pointing viewing elements positioned at or in proximity to a distal end of said tip section, wherein each of said two or more side-pointing viewing elements having a discrete illuminator associated therewith, wherein the field of view provided by the two or more side-pointing viewing elements covers a front and side views; a working channel configured for insertion of a surgical tool; and a pathway fluid injector for inflating and/or cleaning a body cavity into which the endoscope is inserted.

Multi-viewing element endoscope

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.

Circuit board assembly of a multiple viewing elements endoscope

There is provided herein an optical system for a tip section of a multi-sensor endoscope, the system comprising: a front-pointing camera sensor; a front objective lens system; a side-pointing camera sensor; and a side objective lens system, wherein at least one of said front and side objective lens systems comprises a front and a rear sub-systems separated by a stop diaphragm, said front sub-system comprises, in order from the object side, a first front negative lens and a second front positive lens, said rear sub-system comprises, in order from the object side, a first rear positive lens, an achromatic sub-assembly comprising a second rear positive lens and a third rear negative lens, wherein the following condition is satisfied: f≤1.8f, where f is the composite focal length of the total lens system and fis the focal length of said first rear positive lens.

Optical systems for multi-sensor endoscopes

The present specification is directed towards endoscopes, such as colonoscopes, that provide a broader field of view and allow extended access of surgical tools and also enable efficient packing of all necessary elements in the tip section, while maintaining their functionality. Also described are methods and systems for capturing and displaying still and video images using an endoscope corresponding to a left-side looking, a front-looking and a right-side looking viewing element of an endoscopic tip generated in a native aspect ratio.

Compact multi-viewing element endoscope system

There is provided herein a flexible electronic circuit board for a tip section of a multi-camera endoscope, the circuit board comprising a front camera surface configured to carry a forward looking camera, a first side camera surface configured to carry a first side looking camera, a second side camera surface configured to carry a second side looking camera, one or more front illuminator surfaces a configured to carry one or more front illuminators to essentially illuminate the FOV of the forward looking camera, one or more side illuminator surfaces configured to carry one or more side illuminators to essentially illuminate the FOV of the first side looking camera and one or more side illuminator surfaces configured to carry one or more side illuminators to essentially illuminate the FOV of the second side looking camera.

Methods and systems of this disclosure include for capturing and displaying still and video images using an endoscope corresponding to a left-side looking viewing element, a front-looking viewing element, and a right-side looking viewing element of an endoscopic tip generated in a native aspect ratio.

There is provided herein an optical system for a tip section of a multi-sensor endoscope, the system comprising: a front-pointing camera sensor; a front objective lens system; a side-pointing camera sensor; and a side objective lens system, wherein at least one of said front and side objective lens systems comprises a front and a rear sub-systems separated by a stop diaphragm, said front sub-system comprises, in order from the object side, a first front negative lens and a second front positive lens, said rear sub-system comprises, in order from the object side, a first rear positive lens, an achromatic sub-assembly comprising a second rear positive lens and a third rear negative lens, wherein the following condition is satisfied: f&#x2264;1.8, where f is the composite focal length of the total lens system and fis the focal length of said first rear positive lens.

The present specification describes a system and method for computing the temperature of the tip of a multiple viewing elements endoscope based on a measurement of junction temperatures of light emitting diode (LED) illuminators inside the tip. The measurement of temperature is used for taking corrective action if the temperature exceeds a limit. The temperature measurement is used for optimizing image parameters, as the performance of image sensors is affected by changes in ambient temperature.
