4 Way Articulation Hypotube Precision Specification Overview

4 Way Articulation Hypotube belongs to high-end ultra-precision medical micro-tube products, with strict standardized control in dimensional tolerance, outer diameter range, wall thickness and surface finish. Different from ordinary single-function hypotubes, the four-wire omnidirectional steering structure puts forward higher requirements for parameter consistency. Every precision specification is optimized for multi-planar steering coordination, lumen utilization and long-term structural stability, forming a complete high-standard technical system for advanced robotic medical components.

±0.01mm Ultra-High Dimensional Tolerance

The outer diameter dimensional tolerance of 4 Way Articulation Hypotube is strictly controlled at ±0.01mm, achieving micron-level ultra-precision manufacturing. Accurate OD size ensures perfect assembly matching with instrument sheaths, pull-wire channels and distal functional components. Consistent tube body diameter guarantees uniform bending resistance and steering sensitivity in all directions, avoiding unbalanced deflection caused by size deviation. This high tolerance standard is the basic guarantee for precise coordination of four-wire omnidirectional control.

Full-Custom OD Range: Ø1.0mm to Ø15.0mm+

The product supports ultra-wide outer diameter customized specifications, covering micro medical devices to large industrial endoscopic equipment. Small-diameter products (Ø1.0mm–Ø3.0mm) adapt to ultra-fine minimally invasive catheters and micro-robotic surgical instruments, realizing ultra-miniaturized omnidirectional steering. Medium-diameter specifications (Ø3.0mm–Ø8.0mm) are suitable for mainstream gastrointestinal endoscopes and bronchoscopes. Large-diameter tubes (Ø8.0mm–Ø15.0mm+) meet the structural support needs of large-channel robotic-assisted surgical systems, realizing full-scene product coverage.

0.05mm Ultra-Thin Wall Precision Machining

The 4 Way Articulation Hypotube achieves an ultra-thin wall thickness limit of 0.05mm through precision machining. Under the premise of ensuring maximum flexibility for multi-directional bending, it retains excellent radial crush resistance. The ultra-thin wall design greatly expands the internal lumen space, allowing the tube body to integrate four groups of control pull-wires and reserve sufficient central working channels for optics, flushing and suction functions. It realizes the perfect integration of miniaturization, multi-function and high flexibility.

15μm Ultra-Fine Laser Kerf Control

The complex multi-directional puzzle hinge structure of 4 Way Articulation Hypotube requires extremely high cutting precision. The laser kerf width is stably controlled at 15μm, ensuring that each micro-joint has a precise fit gap. The ultra-narrow gap makes the tube body stretch freely during omnidirectional bending without jamming, and the interlocking structure is tightly engaged to avoid looseness. Micron-level kerf precision ensures consistent zero-stretch performance and torque transmission effect of the whole tube segment.

Medical-Grade Ultra-Smooth Surface Standard

After advanced electropolishing treatment, the inner and outer wall roughness of the product is less than Ra 0.2μm. The 100% burr-free and slag-free surface eliminates friction damage to the four delicate control wires, preventing wire fraying and signal jitter. The smooth inner wall also reduces fluid resistance of the working channel, improving the efficiency of intraoperative flushing and suction. The passivation treatment enhances surface biocompatibility and corrosion resistance, adapting to long-term implantation and repeated clinical use.
