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.

An endoscope may have a shaft having a distal end portion and a proximal end portion. The endoscope may also have a first objective arranged at the distal end portion and a first optical axis. The endoscope may also have a second objective arranged at the distal end portion and a second optical axis. The endoscope may also have a lens system disposed within the shaft between the distal end portion and the proximal end portion, the lens system having an optical axis. The first objective and the second objective may be both optically coupled to the same lens system such that first parallel rays from the first objective and second parallel rays from the second objective are input into the lens system. The lens system may be an optical relay system may have at least one relay group or a tube lens group.

An endoscope is provided to examine internal organs with front and rear views. The endoscope comprises a shaft extending from a distal end in a rearward direction along a longitudinal axis towards a proximal end, with the distal and proximal ends defining a hollow channel extended there-through. The endoscope further comprises a first lens positioned adjacent to the distal end and configured to receive a first image in a forward direction along the longitudinal axis, with the forward direction generally 180 degree from the rearward direction. The endoscope further comprises a rearview module positioned adjacent to the distal end. The rearview module comprises a second lens configured to be positioned adjacent to the distal end, and receive a second image in a target direction having a directional component in the rearward direction along the longitudinal axis, independently of the first lens receiving the first image in the forward direction.

Provided is an endoscope having a tip at a distal section thereof, the tip includes a plurality of imaging units, at least one of the imaging units includes at least two optical lens assemblies and at least one optical sensor associated with the at least two optical lens assemblies, wherein each optical lens assembly has a different depth of field, thereby allowing to obtain a multi-focal image of a body cavity. Further provided are systems comprising the endoscope and methods of using the same in various endoscopic procedures.

A tip section of a multi-camera endoscope includes a front-pointing camera on a planar surface of a distal end of the tip section and two side-pointing cameras positioned on a cylindrical surface in proximity to the planar surface such that the side field of view provided by the two side-pointing cameras partially overlaps with the front field of view provided by the front-pointing camera. The tip section further includes 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.

Disclosed is an endoscope system, which comprises an endoscope, the endoscope having at its distal end multiple cameras each having a different field of view (FOV). The system also comprises an image processing box adapted to receive images of different FOVs from the multiple cameras and process the image to form a consolidated image covering 360-degree view of areas surrounding the distal end using the received images of different FOVs and image-stitching techniques.

Devices and methods for treating rhinitis are provided. An integrated therapy and imaging device is provided for single handheld use. The device may have a hollow elongated cannula, a therapeutic element coupled to a distal portion of the cannula, an imaging assembly coupled to the cannula to provide visualization of the therapeutic element, and an articulating region operably coupled to the imaging assembly to articulate the imaging assembly. The imaging assembly may be articulated so as to translate vertically, laterally, axially, and/or rotationally.

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.

The present disclosure provides a medical endoscope system, comprising: a sheath device having an end portion; and an optical sensing device disposed to extend within the sheath device and fixed to the end portion. The optical sensing device has a transmission portion and transmits an optical signal received by the optical sensing device through the transmission portion.

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.
