Coaxial Needle: Precision Layered Access for Image-Guided Interventions.
Coaxial Needle Clinical Purpose
Engineered for sequential instrument deployment during complex biopsies and ablations, our coaxial system establishes a stable access tract through which multiple devices (biopsy guns, RF probes, cryoapplicators) can be introduced with a single tissue penetration. Eliminates repeated punctures to preserve sample integrity and reduce complications.
Coaxial Needle Key Advantages
Dual-Stage Precision
Trocar-tipped inner stylet: Ultra-bevelled 12° cutting edge (HRC 58±2 hardness) ensures clean initial penetration.
Bevel-matched outer cannula: Mirror-polished interior (Ra ≤0.1μm) advances smoothly over stylet with zero tissue drag.
Procedural Control
Laser-etched depth markers (1mm graduations) enable millimeter-accurate placement under CT/ultrasound.
Frosted/flared cannula hub provides a positive-lock grip during device exchanges.
Traceability & Safety
Flat-marked stylet base: Visual/tactile orientation confirms rotational alignment.
The tapered transition zone prevents fluid leakage at the hub junction.
Advanced Material Engineering
Cannula: Seamless SUS 304 stainless steel (ASTM F899 compliant).
Surface: Electropassivated exterior, Hydrophilic coating option.
Hub: MRI-safe polycarbonate with Luer-Lock.
