4A Chiba Needle

SKU: 4A-RA-0001

The Chiba Needle is a fine-gauge, ultra-sharp diagnostic needle engineered for percutaneous fine-needle aspiration (FNA), fluid sampling, and initial access during interventional radiology procedures. Designed with a classic 30 degree bevel tip and a thin-wall cannula, it maximizes internal lumen volume for efficient fluid and cellular retrieval while minimizing trauma to surrounding parenchymal tissue. Manufactured from high-tensile stainless steel with depth markings along the shaft, the Chiba Needle ensures precise control, tactile feedback, and optimal radiopacity under ultrasound or CT guidance.

Key Benefits

  • Ultra-Sharp 30 Degree Bevel Tip: Minimizes insertion force and prevents tissue tearing during percutaneous organ access.
  • Thin-Wall Cannula Architecture: Delivers larger internal lumen volume for efficient fluid aspiration without increasing outer diameter.
  • High Echoic & Fluoroscopic Visibility: Echogenic tip treatments allow precise real-time tracking under ultrasound and CT guidance.
  • Transparent Luer-Lock Hub: Enables immediate visual identification of aspirated fluid or blood return.
  • Exact Depth Calibration: Centimeter-graduated depth markings and adjustable stop wing provide accurate placement control.
