Description
What Is An EUS FNB Needle?
The EUS FNB Needle (Endoscopic Ultrasound-Guided Fine Needle Biopsy Needle) is a medical instrument used to obtain tissue samples under endoscopic ultrasound (EUS) guidance. Unlike the EUS FNA (Fine Needle Aspiration) needle, which is designed to collect only cell samples, the EUS FNB needle is specifically engineered to retrieve high-quality tissue cores. This is particularly beneficial for enhancing the accuracy of pathological diagnoses, especially when histological analysis or molecular testing is required.
This needle is intended for extracting tissue or cells for further examination, and it is primarily used for detecting cancer or other diseases. It is particularly useful for diagnosing the nature of tumors, inflammation, or other abnormalities. In some cases, the EUS FNB Needle may also be employed to locate and evaluate lumps or other unusual findings within the body.

EUS FNB needles are typically made from materials such as cobalt-chromium (Co-Cr), medical-grade stainless steel (304, 316L), Nitinol, or titanium alloy. These materials offer high strength, corrosion resistance, and flexibility.
Common needle tip types for FNB needles include:
- Reverse cutting needles: With reverse cutting slots on the tip to facilitate tissue cutting during puncture.
- Side-hole needles: Featuring side holes on the tip for easier tissue entry into the needle cavity.
- Grasping needles: Designed with a grasping mechanism to capture tissue actively.
Common needle gauges are 19G, 20G, and 22G. Larger gauges (e.g., 19G) are ideal for obtaining larger tissue samples but are more difficult to maneuver. Smaller gauges (e.g., 22G) are better suited for fragile or vascular-rich lesions. The needle tip or body may also feature imaging markers (e.g., platinum coatings) to assist in localization under ultrasound or X-ray.
At Manners Technology, we provide complete material certifications for each component of our EUS FNB needles, ensuring compliance with ISO 10993 or FDA biocompatibility standards. Please note that these needles are custom-made products, not standard items. Manners specializes in providing tailored solutions to meet your specific needs. Contact us for custom orders and expert support.
EUS FNB Needle Product Flow
The manufacturing of EUS FNB needles is a complex process involving material selection, precision machining, surface treatment, and quality control. By optimizing design and manufacturing techniques, high-quality, high-performance needles are produced. With continuous technological advancements, the manufacturing process at Manners Technology has become increasingly intelligent and efficient.
First, we select medical-grade materials that meet industry standards. The material is then drawn into a slender needle body to ensure uniform diameter. This is followed by cutting and shaping to the required length, with the needle tip processed into the desired form (e.g., bevel, reverse cutting slots). The needle body is polished to minimize surface roughness. After basic processing, imaging markers such as platinum or gold coatings are applied to specific areas of the needle tip or body. Finally, we conduct quality inspection and performance testing to ensure the needle's diameter, length, and tip shape meet design specifications, while also testing the puncturing force, flexibility, and imaging effectiveness.
At Manners, we use advanced technologies such as sliding headstock lathes, laser engraving, and grinding to produce EUS FNB needles, with a tolerance of +/- 0.01 mm. Our factory is certified under ISO 9001:2015 and ISO 13485 and is equipped with state-of-the-art machinery, including Citizen L12-1M7 lathes, grinding machines, and 5-axis laser cutters. Each needle is carefully packaged in a PP bag, and custom packaging is available upon request to meet your specific needs.
