Endoscope Insertion Tube Components

Precision control over wall thickness and tube diameter impacts both the mechanical behavior and functional compatibility of insertion tubes. Ultra-thin yet mechanically robust walls produced through advanced extrusion and coiling processes reduce overall tube stiffness while maintaining lumen patency. Maintaining tight dimensional tolerances ensures consistent inner channel diameters, which is essential for unobstructed passage of fiber optics, cables, and irrigation channels. This balance minimizes insertion force and enhances torque responsiveness during complex manipulations within confined anatomical spaces. 

Torque transmission cores fabricated from high tensile strength alloys or composite braids provide the structural backbone for mechanical control. These cores exhibit minimal torsional deformation, translating operator inputs directly to the distal tip with high fidelity. Push force resistance is optimized through material layering and internal support structures that prevent kinking or buckling under compressive loads. The synergy of these design elements enables precise distal end articulation, critical for targeting lesions or conducting biopsy in difficult-to-access regions.
