What am I looking at?
Visual recognition
Long, slender, straight fine-caliber needle with a simple stylet hub and a relatively flexible shaft, giving it a more delicate profile than standard access needles.

Recognition, context, and distinction
What does it do, and where will I see it?
Use & procedural context
Thin, flexible 21- to 22-gauge needle for fine percutaneous access to small or deep targets such as bile ducts, the renal collecting system, or focal lesions. Typical procedural contexts include PTC/biliary drains, nephrostomy, deep abscess access, fine-needle biopsy, and fluid aspiration.
What most clearly distinguishes it from similar devices?
Key distinctions
The Chiba is longer, finer, and more flexible than a standard access needle, making it visually and functionally suited to small or deep percutaneous targets.
