Systems and methods for modular endoscope

A disposable endoscope comprising:

• a distal tip portion including an imaging device, a position sensor and an illumination device;
• a bending section connected to the distal tip portion at a distal end of the bending section, and connected to a shaft portion at a proximal end of the bending section, wherein the bending section is articulated by a plurality of pull wires;
• and
• the shaft portion comprising a wall forming a central tubular bore housing a plurality of load transmission tubes for accommodating the plurality of pull wires, wherein a distal end of the plurality of load transmission tubes is anchored to a junction interface between the bending section and the shaft portion thereby forming a modular component for easy assembly to the bending section and the central tubular bore, wherein a proximal end of the plurality of transmission tubes is fixed to a proximal end of the shaft portion such that only the distal end and proximal end of the plurality of load transmission tubes are connected to the shaft portion thereby transmitting load directly from the distal end to the proximal end without compressing the wall of the shaft portion, and wherein a length of each load transmission tube is greater than a length of the shaft portion between the junction interface and the proximal end of the shaft portion by a predetermined percentage to reduce an axial compression force applied to the shaft portion thereby improving stability of the shaft portion, and wherein the predetermined percentage allows for a movement of each load transmission tube within the central tubular bore of the shaft portion to adapt to geometry changes to the length of the shaft portion.
