Endoscope comprising a flexible insertion tube and a bending portion

An endoscope comprising:

• a flexible insertion tube;
• and
• a bending portion comprising a sleeve and controllable from a proximal side, the bending portion being distally connected to the insertion tube,
• wherein in the bending portion at least one pull rope longitudinally extends to provide for a pivoting movement of the bending portion, the at least one pull rope being anchored to a distal end of the bending portion,
• wherein a biased bendable divider dividing a cross-section of the sleeve into separate first and second chambers having the same cross sectional size is arranged in a longitudinal direction of the bending portion in parallel to the at least one pull rope, the divider having a predefined bend toward one side of the bending portion such that the bending portion is pre-bent to the one side,
• wherein the at least one pull rope is arranged in only the first chamber,
• wherein in a pre-bent state of the bending portion, the first chamber is located outside of a radius of the divider, and
• wherein the second chamber includes at least one of a camera cable and a light conductor and is inside of the radius of the divider.
