1. A tip section of an endoscope, the tip section comprising:
a substantially cylindrical fluid channeling component having a proximal section, a first fraction, a second fraction and a third fraction,
the proximal section comprises an auxiliary channel that divides into a first side service channel and a second side service channel, said proximal section having a distal end face;the first fraction comprises a housing that extends distally from the distal end face of the proximal section, said housing having exit openings for the first and second side service channels proximal to a distal end of the housing of the first fraction, said exit openings disposed on opposing sides of the fluid channeling componentthe third fraction comprises a housing that extends distally from the distal end face of the proximal section and encases a working channel therein;the second fraction comprises a void distal to the distal end face of the proximal section, said void prevents the first and third fractions from contacting each other; an electrical assembly configured to fit within said second fraction, wherein the electrical assembly comprises at least one front-pointing camera, at least one front illuminator and an integrated circuit board having mounted thereon at least one side-pointing camera; and a tip cover section configured to be removably attachable to said fluid channeling component and configured to receive said electrical assembly, wherein the tip section comprises a front working channel configured to mate to said working channel of the fluid channeling component and provide a contiguous pathway for receiving a medical tool. |
