Chiba Needle – Sizes (16 : 22)
The Chiba Needle is a disposable interventional radiology instrument featuring a sharp angled Chiba-cut stainless steel tip for precise percutaneous puncture. It is used for soft-tissue biopsy, fluid aspiration, and guided drainage of organs including the liver, kidney, lung, thyroid, and pancreas under CT or ultrasound guidance. Sterile (ETO), latex-free, and non-pyrogenic for single use. Available in 16, 18, 20, and 22G gauges to accommodate a wide range of diagnostic and interventional procedures, from larger core sampling to fine-needle aspiration of delicate tissues.

Questions & answers
What is the difference between a Chiba needle and a spinal needle?
The Chiba needle is specifically designed for image-guided percutaneous biopsy and aspiration of soft tissues, featuring a sharp angled Chiba-cut tip. A spinal needle is used to inject anesthetic into the subarachnoid space and has a different tip design (Quincke or Pencil Point).
How do I choose between the available gauges: 16, 18, 20, and 22G?
Larger gauges such as 16G and 18G are preferred when larger core tissue specimens are needed, as in liver or kidney biopsies. Finer gauges like 20G and 22G are better suited for sensitive or smaller organs such as the thyroid or pancreas, where minimal trauma is essential. The appropriate gauge is determined by the physician based on the procedure type and organ location.
Is the Chiba needle single-use / disposable?
Yes, the Chiba needle is ETO-sterilized and intended for single use only. Re-sterilization or reuse is not permitted to prevent cross-contamination and infection risk.
Which organs can be biopsied using the Chiba needle?
The Chiba needle can be used to biopsy the liver, kidney, lung, breast, thyroid, pancreas, prostate, ovary, and other soft tissues or undiagnosed tumors under imaging (CT or ultrasound) guidance.
