• High surface finish , ensures smoothness and low resistance





FAQs:

Q: How is the compressive strength and collapse resistance ensured after the thin-wall hypodermic tube is bent?

A: We select high-strength medical-grade stainless steel (e.g., 304/316L) or special alloys​ as the base material, combined with precision cold drawing processes​ to optimize the metal's crystalline structure while reducing wall thickness. Regarding the bending process, we control the bending radius with precision molds​ to ensure no flattening or excessive thinning​ occurs at the bend. This allows the tube to maintain sufficient radial support​ while being highly flexible, effectively resisting external pressure and preventing collapse within complex lumens.


Q: How is the surface of the bent section treated? Will it affect the passage of internal instruments?

A: After bending, the tube undergoes specialized stress-relief treatment and fine electropolishing. This ensures a uniform, smooth surface (low Ra value)​ on both the inner and outer sides of the bend, free from any burrs or geometric distortions that could obstruct the lumen. This mirror-grade smooth transition​ significantly reduces the coefficient of friction, ensuring that guidewires, catheters, or other miniature instruments pass through the curved section smoothly without obstruction or risk of jamming.


Q: In which specific medical scenarios is this thin-wall bent outer tube mainly used?

A: It primarily serves as a versatile protective sheath or outer tube for minimally invasive interventional devices. Typical applications include: bending working channels for endoscopes (e.g., bronchoscopes, ureteroscopes), delivery sheaths for neurointerventional or cardiovascular interventional devices, and outer casings for biopsy/ablation devices that need to traverse joints or complex anatomical structures. Its bent design is particularly suitable for procedures requiring conformity to physiological curved paths.


Q: Can specific bending angles and radii be customized according to our anatomical models or device drawings?

A: Yes, we specialize in high-precision non-standard customization. We accept customization requests based on 3D anatomical data or engineering drawings. Utilizing multi-axis CNC tube benders or laser forming technology, we can accurately replicate any complex spatial bending morphology. Whether it is a single bend, double bend, or S-shaped bend, we guarantee high shape fidelity and dimensional consistency, meeting your stringent requirements for device conformity.
