FAQs:

Q: What is the difference between the "flexibility" of a snake bone tube and ordinary flexible tubes? How is this advantage reflected in complex procedures?

A: Ordinary flexible tubes typically bend as a whole, with a large bending radius and a tendency to kink; whereas our snake bone tube is a multi-segment linked structure​ manufactured via precision spiral winding or micro-braiding. Its advantage lies in its excellent "active steerability" and "anti-kinking" properties: when navigating narrow, tortuous anatomical lumens (such as vascular branches or ureters), each tiny metal segment can independently conform to path changes, enabling smooth "serpentine" steering, while maintaining absolute patency of the internal lumen. Furthermore, when adjusting direction frequently, it will not develop irreversible creases or blockages like ordinary plastic tubes, ensuring operational continuity and safety.

Q: How does the snake bone tube ensure structural strength and durability during high-frequency bending or long-term dynamic use?

A: We have optimized both material and structural design. First, the tubing substrate is made of medical-grade nitinol (or stainless steel) with superelasticity and shape memory properties, offering excellent resistance to metal fatigue. Second, the spiral pitch and bending angle of the snake bone are precisely optimized through mechanical simulation and finite element analysis (FEA), allowing stress to be evenly distributed across each tiny segment during bending, preventing localized stress concentration that could lead to breakage or deformation. Therefore, it can withstand tens of thousands of dynamic bending cycles, making it highly suitable for interventional or therapeutic scenarios requiring repeated positional adjustments.

Q: How is the tip of the snake bone tube treated? Can it be adapted to specific medical accessories or instruments?

A: The tip of the snake bone tube can be customized with precision treatments​ based on application requirements. We offer options such as micro-beveled, flat-cut, smoothly ground, or specific angle beveled tips​ to accommodate different steering needs. Additionally, the tail (or head) supports connection to standard Luer Lock fittings, or direct integration with specific catheters, guidewires, syringes, and other instruments. Whether used for fluid delivery, instrument guidance, or imaging tracking, we provide highly compatible interface solutions.
