Articulated tip part for an endoscope

A medical device operable to obtain images of an internal cavity of a patient, the medical device comprising:

• a handle;
• a flexible tube having a proximal end adjacent the handle and a distal end, the distal end of the flexible tube having an outer surface;
• a camera assembly;
• a front end cap housing the camera assembly, the front end cap having an outer surface;
• a bending section integrally formed in one piece and extending from the flexible tube, the bending section including a proximal end segment, a distal end segment, and intermediate segments between the proximal end segment and the distal end segment, the intermediate segments hingedly connected to each other,
• wherein the proximal end segment includes a proximal end segment peripheral wall defining an internal space, the proximal end segment peripheral wall comprising an inner surface, an outer surface, and a cavity extending radially outwardly from the inner surface toward the outer surface, the distal end of the flexible tube positioned at least partly in the internal space of the proximal end segment peripheral wall with the cavity overlapping the outer surface of the flexible tube, and
• wherein the distal end segment includes a distal end segment peripheral wall defining an internal space, the distal end segment peripheral wall comprising an outer surface, an inner surface, inner surface protrusions extending from the inner surface toward the internal space and distributed circumferentially, and through-holes extending radially outwardly from the inner surface to the outer surface, the front end cap positioned at least partly in the internal space of the distal end segment peripheral wall with the through-holes overlapping the outer surface of the front end cap;
• a first protrusion of a first hardened adhesive bonded to the outer surface of the flexible tube, the first protrusion extending into the cavity of the proximal end segment peripheral wall;
• and
• a second protrusion of a second hardened adhesive bonded to the outer surface of the front end cap, the inner surface protrusions not comprising the second protrusion, and the second protrusion extending into the through-holes of the distal end segment peripheral wall.
