Systems and methods for configurable endoscope bending section

An articulating flexible endoscope comprising:

• a bending section connected to a distal tip portion of the articulating flexible endoscope at a first end, and connected to a shaft portion of the articulating flexible endoscope at a second end, wherein at least a portion of the articulating flexible endoscope is disposable;
• a pull wire coupled to the distal tip portion at a first location and is configured for articulating the bending section;
• and
• a first tube for accommodating the pull wire and is concentric with the pull wire, wherein a distal end of the first tube is coupled to a second location on the bending section or on the shaft portion, wherein a proximal end of the first tube is coupled to a proximal portion of the articulating flexible endoscope and wherein the first tube is a hypotube and a wall thickness or a material of the hypotube is selected to transmit articulation reaction loads from the bending section to the proximal portion of the articulating flexible endoscope,
• wherein an effective bending section of the articulating flexible endoscope is adjusted by varying i) a length between the first location and the second location or ii) the second location.
