1. Medical-Grade Stainless Steel Construction

Manufactured from ASTM-standard 304/316L Surgical Stainless Steel, compliant with ISO 10993 biocompatibility standards. It offers superior resistance to corrosion from bodily fluids and disinfectants, and is fully autoclavable (121°C steam sterilization) for safe reuse, significantly reducing operational costs.

2. Precision Slotted Tip Design

Features a laser-cut or precision-milled longitudinal slot at the tip. Unlike conventional side-hole needles, this open-channel design provides a wider drainage pathway, effectively preventing clogging by tissue debris, blood clots, or viscous fluids, ensuring uninterrupted flow.

3. High Aspect Ratio for Deep Access

Engineered with an ultra-long, slender shaft (high length-to-diameter ratio) and exceptional straightness. The tip is precision-ground to a sharp bevel, minimizing penetration resistance and allowing for accurate access to deep-seated tissues (fascia, muscle) with minimal collateral damage.

4. Advanced Surface Finish & Consistency

Processed via CNC machining, ultrasonic cleaning, and electropolishing. The inner lumen boasts a mirror-like finish (Ra ≤ 0.4μm) to reduce flow resistance. Strict dimensional tolerances (±0.01mm) guarantee consistent sharpness and performance across every batch.

5. Ergonomic Hub Interface

Available with a smooth transition shaft or standard Luer Lock hub for secure, leak-proof connections to syringes, catheters, and drainage systems. The smooth surface finish ensures optimal grip and tactile feedback during delicate procedures.

6. Global Regulatory Compliance

Produced under a stringent ISO 13485 Quality Management System. Full batch traceability and compliance with FDA, CE, and NMPA regulations ensure a reliable supply chain for hospitals and distributors worldwide.
