Chiba Needle – Precision Tool for Biopsy and Diagnostic Procedures

Introduction to Chiba Needles – Precision Tools for Diagnostic & Interventional Procedures

The Chiba Needle is a fine, flexible puncture needle widely used in diagnostic and interventional radiology, urology, and oncology. It is primarily designed for percutaneous access, biopsy procedures, and drainage interventions under fluoroscopic or ultrasound guidance. The Chiba needle’s thin-wall design allows smooth guidewire insertion, while its sharp beveled tip ensures precise, atraumatic puncture.

Development & Evolution – Advancements in Fine Needle Aspiration & Biopsy Techniques

The Chiba Needle was first introduced in Japan for percutaneous transhepatic cholangiography (PTC). Over time, its high precision and minimal invasiveness made it a global standard for percutaneous access in a wide range of procedures, including nephrostomy, abscess drainage, and interventional radiology.

Brief Overview – Why Chiba Needles Are Widely Used in Radiology and Urology

The Chiba Needle provides safe, accurate, and minimally traumatic percutaneous access for guidewire placement, diagnostic aspirations, and interventional procedures.

Clinical Applications – Role in Biopsy, PCN (Percutaneous Nephrostomy), and Cytology

• Percutaneous Nephrostomy (PCN)
• Percutaneous Nephrolithotomy (PCNL)
• Biopsy Procedures (Liver, Kidney, Lung)
• Percutaneous Transhepatic Cholangiography (PTC)
• Abscess Drainage
• Interventional Radiology Access Procedures
• Urology Diagnostic Access

Also Known As – Fine Aspiration Needle, Percutaneous Access Needle

Chiba Access Needle, PCN Chiba Needle, Radiology Puncture Needle, Percutaneous Biopsy Needle, Urological Access Needle, Interventional Chiba Needle, Fine Puncture Needle, Guidewire Introduction Needle, Kidney Puncture Needle, Cholangiography Needle

Frequently Paired With – Syringes, PCN Catheters, and Biopsy Guns

• Guide Wire (Zebra, Hydrophilic, PTFE, Nitinol)
• Fascial Dilator Set
• Amplatz Dilator Set
• PCN Catheter / Nephrostomy Catheter
• Ureteral Access Sheath
• C-Arm / Ultrasound Machine

How to Use – Safe Insertion & Handling Guidelines for Optimal Results

1. Select the appropriate gauge and length of Chiba Needle.
2. Under fluoroscopic or ultrasound guidance, advance the needle towards the target organ/cavity.
3. Confirm correct placement via aspiration of bile, urine, or other fluids (depending on procedure).
4. Introduce a guidewire through the needle lumen if further dilation or catheter placement is required.
5. Withdraw the needle carefully while leaving the guidewire in place.
6. Follow sterile technique and dispose of single-use needles appropriately.
