Engineering & Application Overview
The 4-Way Articulation Hypotube is the core structural skeleton for advanced bending sections. By accommodating four orthogonal control wires, it empowers surgeons with true 360-degree steerability, enabling seamless retroflexion (U-turns) and precise targeting within complex anatomical structures like the GI tract or pulmonary pathways.
Manufactured using ultra-fast Femtosecond Laser Micro-machining. This cold-cutting process creates highly complex, interlocking articulation joints with zero thermal distortion, ensuring every micro-hinge moves with frictionless precision.
• Omnidirectional Steering: Achieves full 360° multi-planar articulation for unrestricted surgical access.
• Interlocking Integrity: Puzzle-cut patterns ensure zero-stretch under tension and prevent tube collapse during extreme bending.
• Smooth Actuation: Burr-free internal profiles guarantee minimal friction for the four delicate control wires.
4-Way steerable Bending Sections for Gastrointestinal (GI) Endoscopes, Colonoscopes, Bronchoscopes, and Robotic-assisted MIS Delivery Catheters.
Extensively cycle-tested for high-fatigue endurance. Manufactured in strict compliance with ISO 13485 standards, ensuring zero-defect performance over thousands of severe bending cycles.
