- Dual‑lumen coaxial structure supports repeated sampling operations without repeated puncture, reducing patient trauma.
- Clear laser depth marking lines help doctors accurately control insertion depth during clinical operation.
- Reliable plastic luer hub assembly ensures stable connection with matched medical instruments.
- Electropolished stainless steel cannula features smooth inner and outer surface to lower friction risk.
- Tip geometry, shaft length, mark position and hub structure can be fully customized according to drawings or samples.
FAQ:
Q1: What stainless steel grades are available for this customized coaxial needle?
A1: Medical grade 304 and 316 stainless steel are standard tube materials. Batch material test certificates can be provided for medical device registration and quality traceability. Special alloy materials are acceptable upon your request.
Q2: What dimensional tolerances can you achieve for coaxial cannula and hub assembly?
A2: Key dimensions including outer diameter, inner bore and wall thickness can reach precision tolerance up to ±0.02mm. Luer hub assembly complies with standard interface specifications. Final tolerance depends on your drawing requirements.
Q3: Can secondary processes such as laser depth marking, side hole drilling and tip grinding be finished in‑house?
A3: Yes, laser depth marking, side hole processing, tip angle grinding and plastic hub assembly are all completed in‑house, effectively avoiding quality risks brought by external subcontracting.
Q4: Are these coaxial needles supplied sterile? What sterilization modes are compatible?
A4: Standard delivery is non‑sterile finished components without sterilization service. This needle supports EO ethylene oxide, gamma irradiation and autoclave steam sterilization for your downstream processing.
Q5: What are sample and bulk production lead‑times? What inspection documents can you provide?
A5: Custom sample lead‑time is 7‑12 working days according to structural complexity. Bulk production lead‑time will be confirmed after drawing approval. Dimension inspection reports and batch traceability documents can be offered as requested.
