Riveted Bending Section｜Product Overview

This product is a riveted bending core steering component for endoscopes, used in the assembly of the distal bending assembly of medical and industrial endoscopes.

Key Parameters

Outer Diameter (OD): 4.4mm, small-diameter specification, with excellent passage through narrow lumens

Inner Diameter (ID): 4.2mm, large through-lumen structure, allowing routing of camera modules, light guide fibers, water/air channels, and miniature diagnostic and therapeutic instruments

Effective bending length: 45mm

Structure: Mortise-and-tenon articulated joint structure

Steering: Bidirectional bending

Applications: Medical flexible endoscopes, flexible industrial inspection endoscopes

Product Features

1. Thin-walled large through-lumen construction with high internal space utilization

2. Riveted joints bend smoothly without sticking, with stable bending angles and smooth control feel

3. Precision machined and formed with high coaxiality, no play or wobble in steering, and stable imaging

4. Smooth, low-friction outer cylindrical surface for smooth insertion, resistant to corrosion from body fluids and oil

5. Positioning features are reserved at the head and tail, facilitating threading of traction wires and outer sheath covering, and suitable for assembly-line mass production

Core Advantages

Smooth access through narrow lumens｜Integrated routing through large through-lumen｜Durable riveted bending｜Simple bidirectional control｜Convenient mass-production assembly
