Abstract
An articulated tip part suitable for an endoscope, where the articulated tip part includes a distal end segment, a proximal end segment and a number of intermediate segments arranged between the distal end segment and the proximal end segment, the segments being joined together to form an articulated assembly of segments, a passage running along the length of the articulated tip part, and a bending element, the bending element being fastened to at least two segments and being arranged along a path which is essentially parallel to a centerline of the articulated tip part.

An articulated tip part suitable for an endoscope, where the articulated tip part comprises:
- segments including a distal end segment, a proximal end segment, and an intermediate segment having a first part and a second part, the intermediate segment arranged between the distal end segment and the proximal end segment, said segments being joined together to form an articulated assembly of segments;
- a passage running along a length of the articulated tip part;
- a bending element having a first side opposite a second side, said bending element being fastened to at least two of the segments and being arranged along a path which is essentially parallel to a centerline of the articulated tip part,
- wherein the bending element comprises recesses having a closed perimeter, the recesses configured to positively and mechanically engage with material of the intermediate segment to fasten the first part to the first side and the second part to the second side, of the bending element wherein the recesses are arranged to pass through the bending element such that the material of the segments passes through the bending element and the bending element completely surrounds the material of the segments passing through the bending element.
The articulated tip part of 1, wherein a dimension of the bending element which is perpendicular to a longitudinal extent of the bending element is greater than a minimum inside diameter of the passage.
An articulated tip part suitable for an endoscope, where the articulated tip part comprises:
- segments including a distal end segment, a proximal end segment, and an intermediate segment having a first part and a second part, the intermediate segment arranged between the distal end segment and the proximal end segment, said segments being joined together to form an articulated assembly of segments;
- a passage running along a length of the articulated tip part;
- a bending element having a first side opposite a second side, said bending element being fastened to at least two of the segments and being arranged along a path which is essentially parallel to a centerline of the articulated tip part,
- wherein the bending element comprises protrusions extending perpendicularly to a plane parallel to a main surface of the bending element, the protrusions configured to positively and mechanically engage with material of the intermediate segment to fasten the first part to the first side and the second part to the second side, of the bending element,
- wherein the protrusions of the bending element extend into the material of the intermediate segment, and wherein the protrusions comprise a base portion that is smaller than a tip portion thereof.
