Abstract:
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 seperated 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(first rear positive lens) =1.8f, where f is the composite focal length of the total lens system and f(first rear positive lens) is the focal length of said first rear positive lens.
Abstract:
There is provided herein a tip section of a multi-camera endoscope, the tip section comprising: a fluid channeling component for a tip section of a multi-camera endoscope, the fluid channeling component comprising one or more fluid channels configured for flowing for insufflation and/or irrigation fluid, and one or more support elements adapted to receive, support and/or secure a flexible electronic circuit board and/or one or more of a front camera, a side camera, an optical assembly, and a light source attached thereto; and a folded flexible electronic circuit board.
Abstract:
There is provided a tip section of a multi-camera endoscope, the tip section comprising a unitary fluid channeling component adapted to channel fluid for insufflations and/or irrigation, the unitary fluid channeling component comprising: a proximal opening adapted to receive a fluid tube, the proximal opening being in fluid flow connection with a front fluid (I/I) channel and a side fluid channel.
Abstract:
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.
Abstract:
