Multi-element cover for a multi-camera endoscope

摘要

There is provided herein a tip section of a multi-camera endoscope, the tip section comprising: a front looking camera and a front discrete illuminator to essentially illuminate the Field Of View (FOV) of said front looking camera; a right side looking camera and a right discrete illuminator to essentially illuminate the FOV of said right side looking camera; a left side looking camera and a left discrete illuminator to essentially illuminate the FOV of said left side looking camera; and a multi component cover configured to cover and seal said tip section such as to essentially prevent entry of fluids from the environment of said endoscope to inner parts of said tip section.

1. A tip section of a multi-camera endoscope, the tip section comprising:
a unitary fluid channeling component comprising a front fluid channel leading to a front fluid channel opening at a distal end of the unitary fluid channeling component and a working channel leading to a working channel front opening at the distal end of the unitary fluid channeling component; an electronic circuit board comprising a front looking camera, a right side looking camera, and a left side looking camera; and a multi component cover configured to cover and seal said electronic circuit board and unitary fluid channeling component so as to prevent physically exposing said electronic circuit board and unitary fluid channeling component to fluids, wherein the multi component cover comprises:
a unitary first component configured to cover a first side portion of said electronic circuit board and the unitary fluid channeling component and to cover the distal end of said electronic circuit board and the unitary fluid channeling component, wherein the unitary first component comprises a distal face having a plurality of openings and a first curved side wall, attached to said distal face, extending longitudinally along a side of the tip section and wherein the plurality of openings of the distal face of the unitary first component is configured to mate to the front fluid channel opening and working channel front opening in the unitary fluid channeling component; anda second component configured to cover a second side portion of said electronic circuit board and the unitary fluid channeling component, wherein the second component comprises a second curved side wall having a side edge and a distal edge and wherein the second curved side wall is adapted to attach to the first curved side wall along said side edge and is adapted to attach to the distal face along said distal edge.
