1. A flexing structure configured for an insertion tube of a medical device, the flexing structure comprising:
a tubular vertebrae with a proximal tubular vertebra and a distal tubular vertebra;
at least one actuating cable surrounded by a sheath over at least part of a length of the flexing structure;
a tube cut with lines cut using an energy-beam to create the tubular vertebrae that nest in one another via cut-out areas forming pivots for rotation around pivot axes, the lines being configured to delimit, between the tubular vertebrae, notches cut in the tube to form flexing zones for the tubular vertebrae of the flexing structure in at least one flexing plane perpendicular to the pivot axes,
the proximal tubular vertebra comprising:
for each actuating cable, a radial and axial blocking system for the sheath, the radial and axial blocking system comprising:
an elongate cutout configured to delimit two stop edges that limit the radial engagement of the sheath in the elongated cutout,
wherein the elongated cutout opens towards the distal part of the elongated cutout into a slot delimited by at least two cutout lines between which there is attached a pressing tab configured to press the sheath radially against the two stop edges of the elongated cutout, and
wherein the slot is bordered by a rim to axially stop the sheath, the distal end of the sheath being pressed against the rim.
