- Adopt precision tube processing and tip grinding, standard tolerance up to ±0.02mm, stable dimension matching with inner needle.
- Split tail structure enables easy tearing and quick removal after puncture, simplify minimally invasive operation steps.
- Sharp bevel tip provides smooth penetration, reduces tissue damage during insertion. Stainless steel material delivers good rigidity and corrosion resistance.
- Outer diameter, wall thickness, total length and tip shape can be fully customized according to customer drawings or samples.
- Strict dimensional and visual inspection for each batch, stable batch consistency for clinical puncture procedures.
FAQ:
Q1: What stainless steel grades are available for this tear away needle sheath?
A1: We mainly supply medical grade 304 and 316L stainless steel. 316L is recommended for tissue contact use with superior corrosion resistance.
Q2: What surface finish is used for this tear away needle sheath?
A2: We apply standard surface finish Ra0.8-1.0μm for this product. If you have special high polishing requirements, please inform us in advance for separate process evaluation and quotation.
Q3: Which parameters of the tear away sheath support customization?
A3: Tube outer diameter, wall thickness, total length, bevel angle and tail split size are customizable within our processing capacity under ±0.02mm tolerance. Please provide technical drawings for feasibility evaluation.
Q4: How do you eliminate micro burrs on the split slot and bevel tip?
A4: After tube cutting, tip forming and slot machining, multi-step deburring and cleaning will be performed. Each finished sheath will be inspected to remove micro burrs.
Q5: Can you provide custom samples? What information needs confirmation before sample production?
A5: Custom samples are available for assembly and penetration test. Before sample order, we need to confirm material grade, dimension parameters, tip & slot requirement and surface finish. Sample cost depends on processing complexity, mass production can start after sample specification confirmation.
