Tear-away structure allows convenient opening after insertion, helping reduce post-procedure removal difficulty.
Thin-wall cannula design provides sufficient lumen space while maintaining smooth outer diameter control.
High-quality stainless steel material delivers good strength, corrosion resistance and biocompatibility.
Smooth inner and outer surfaces reduce friction during insertion and withdrawal.
Fully customizable tip shape, tear section length, outer diameter and total length according to drawings or samples.
Q1: What materials are available for this tear-away sheath needle?
A1: Medical grade 304 and 316 stainless steel are standard options. Other medical alloy materials can be customized upon request. Batch material certificates can be provided for quality traceability and medical device registration.
Q2: Can the tear-away section length and peeling force be adjusted?
A2: Yes, the length of the tear section, notch position and peeling performance can be adjusted according to your product design and operational requirements.
Q3: What dimensional tolerance can you achieve for the sheath tube and inner bore?
A3: Key dimensions such as outer diameter, inner diameter, wall thickness and total length can reach tolerance up to ±0.005mm. The final achievable tolerance depends on tube size and structural complexity.
Q4: Are these tear-away sheath needles supplied sterile? Which sterilization methods are compatible?
A4: Our standard supply is non-sterile finished components, and sterilization service is not included. They are compatible with EO, gamma irradiation and autoclave steam sterilization for downstream customer processing.
Q5: Can you provide custom samples before bulk production? What inspection documents can you offer?
A5: Yes, custom samples can be manufactured for performance verification before mass production. We can provide dimension inspection reports, surface quality records and batch traceability documents according to your requirements.
