Special-shaped Needle: Precision-Engineered Solutions for Complex Medical Challenges
Special-shaped Needle Innovation Purpose
We pioneer the design and manufacture of non-standard needle geometries to overcome limitations in minimally invasive procedures. Our custom-engineered solutions enable breakthroughs in accessing confined anatomies, delivering novel therapies, and optimizing device-tissue interactions, transforming conceptual medical innovations into clinical reality.
Key Advantages:
Complex Micro-Edge Grinding
Advanced capabilities in compound multi-facet grinds, reverse back-cuts, stepped micro-tapers, and radius grinds for demanding incision and puncture needs.
Micro-Deburred, Zero-Burr Edges
Precision electropolishing eliminates roll-overs, microscopic burrs, and fishhooks to prevent tissue tearing.
Ultra-Narrow Tolerances & Straightness
Strict control over OD, ID, wall thickness, and runout ensures smooth alignment with outer cannulas or molded hubs.
Ultraclean Washing&Degreasing
Multi-stage ultrasonic cleaning and WFI rinsing leave internal and external surfaces free of lubricants and particles.
Fully Tailored Geometry & End Machining
Custom bevel angles, lengths, proximal chamfering,side-hole drilling, or locating slots built to customer prints.
Quality Control (ISO 13485 QMS)
100%High-Speed Online Vision Inspection
Real-time screening of custom tip geometries, micro-burrs, eccentricity, and edge angles with automatic defect sorting.
Micro-Cleanliness & Residue Monitoring
Strict lot-by-lot inspection for particulate contamination and degreasing residues.
Full-Dimension &Penetration Testing
Batch auditing of OD, ID, wall uniformity, and penetration resistance.

FAQs
Q: What is the slant of a needle called?
A: Bevel: This is the slanted tip of the needle that makes skin penetration easier. The length and angle of the bevel can vary depending on the specific type of needle.
Q: Which needles hurt the least?
A: The needles that hurt the least are those with a smaller diameter, specifically those with a higher gauge number (e.g., 32-gauge or 34-gauge) compared to larger, lower-gauge needles (e.g., 25-gauge or 30-gauge). Shorter needles, such as microneedles that are only 1–3 mm long, are also designed to minimize pain by remaining within the skin. However, the type of needle and the specific body site matter, and some studies have found no difference in pain between certain needle sizes.
