—— SHOMEA Medical-Grade Stainless Steel Needles & Trocars ——

1. Medical-Grade Stainless Steel Construction

Manufactured from 316L surgical-grade stainless steel, fully compliant with ISO 13485 and ASTM F138/F139 international standards. The material offers exceptional biocompatibility, corrosion resistance, and minimal ion leaching, ensuring safety for prolonged tissue contact. Designed to withstand repeated autoclave (steam) and Ethylene Oxide (EO) sterilization cycles without degradation.

2. Ultra-Precision Ground Tip for Minimal Trauma

The needle tip is engineered using high-precision triple-bevel or tapered grinding technology, creating an extremely sharp and geometrically symmetrical cutting edge. This design significantly reduces penetration resistance, allowing for accurate access to target areas while minimizing tissue tearing, drag, and collateral damage—ideal for minimally invasive surgery, biopsy, and injection procedures.

3. Mirror-Polished Surface for Hygiene & Sterilization

The entire needle shaft undergoes electrolytic mirror polishing, achieving a surface roughness of Ra ≤ 0.2μm. This ultra-smooth, crevice-free finish not only facilitates effortless cleaning and sterilization but also drastically reduces blood residue, protein adhesion, and bacterial colonization, meeting stringent hospital infection control standards.

4. Standardized Tolerances for Seamless Compatibility

Outer diameter, wall thickness, and length are manufactured to strict medical-industry tolerances (±0.01mm). This guarantees seamless connectivity with standard syringes, catheter systems, endoscopic accessories, and biopsy devices, ensuring stable performance and eliminating fitting issues in clinical settings.
