Claim 11:
12. An endoscope comprising:
an insertion tube having a proximal passive tubular flexible section integrally formed with a distal angled section;
individual cuts provided on the flexible section, wherein adjacent individual cuts are equidistant from one another
a plurality of first transverse cuts provided along a longitudinal direction of the flexible section such that each first transverse cut of the plurality of first transverse cuts is positioned after a same predetermined number of consecutive individual cuts, each said first transverse cut being shorter than the individual cuts in a width direction of the flexible section;
a plurality of second transverse cuts provided in the longitudinal direction of the flexible section such that each second transverse cut of the plurality of second transverse cuts is positioned after the same predetermined number of the consecutive individual cuts, wherein a said first transverse cut and a respective said second transverse cut are on opposite sides of a circumference of the flexible section, and are coplanar with each other along a plane orthogonal to the longitudinal direction of the flexible section;
a first strip section of the material of the flexible section provided between a said first transverse cut and an adjacent individual cut of the predetermined number of consecutive individual cuts to form a first cable guide lug when the first strip section is bent toward a center of the insertion tube; and
a second strip section of the material of the flexible section provided between a said second transverse cut and another adjacent individual cut of the predetermined number of consecutive individual cuts to form a second cable guide lug when the second strip section is bent toward the center of the insertion tube, wherein the first cable guide lug and the second cable guide lug are on opposite sides of an inner circumference of the flexible section and are coplanar with each other along the plane orthogonal to the longitudinal direction of the flexible section.
