Endoscope Comprising a Bending Section Having Displaced Steering Wire Lumens

A visualization system comprising an endoscope, the endoscope comprising:

• an handle;
• an insertion cord extending from the handle, the insertion cord comprising an insertion tube and a bending section having a bending section body, the bending section body having a diameter in the range of 2.5 mm to 3.5 mm;
• and
• a working channel tube;
• a first steering wire portion;
• a second steering wire portion;
• the bending section body comprising segments and hinges keeping together, and formed integrally with, the segments, the bending section body having a center axis and a center plane traversing the center axis, the center plane dividing the bending section into a first bending section side and a second bending section side, and the segments comprising:
• passages that together form a working channel lumen, the working channel lumen having a non-circular cross-section and the working channel tube positioned, at least in part, in the working channel lumen;
• first steering wire lumens configured to accommodate the first steering wire portion, the first steering wire lumens displaced with respect to the center plane towards the first side by a distance (d) which is greater than or equal to 8% of the diameter;
• and
• second steering wire lumens configured to accommodate the second steering wire portion, the second steering wire lumens displaced with respect to the center plane towards the first side by the distance (d).
