Description
What Is An EUS Guided Fine Needle?
EUS Guided Fine Needle is a medical device used for minimally invasive diagnosis and treatment under the guidance of Endoscopic Ultrasound (EUS). With real-time imaging from EUS, it precisely targets and punctures the lesion to obtain cell or tissue samples or perform interventional procedures. The main types of EUS Guided Fine Needles are EUS FNA (Fine Needle Aspiration) and EUS FNB (Fine Needle Biopsy).
Shenzhen Manners Technology, a leading OEM manufacturer based in Shenzhen, China, specializes in the research and production of EUS Guided Fine Needles. We offer a range of needle tip designs (including reverse cutting and side-hole needles) and needle sizes (19G, 20G, 22G, 25G) to meet various lesion types and clinical needs.
Comparison of EUS FNB vs. EUS FNA
EUS Guided Fine Needle Aspiration is primarily used to obtain cell samples for cytological examination. The finer needle sizes (such as 22G, and 25G) are ideal for fragile or vascular-rich lesions. EUS FNB (Fine Needle Biopsy) is used to obtain tissue cores for histological examination and molecular testing. The coarser needle sizes (such as 19G, and 20G) are suitable for lesions requiring high-quality tissue samples.

Applications of EUS Guided Fine Needle
Endoscopic Ultrasound (EUS) combines endoscopy and ultrasound technology to provide clear imaging of lesions in the digestive tract and surrounding organs. The fine needle is inserted through the endoscope's working channel and, under ultrasound guidance, penetrates the digestive tract wall to reach the target area for sampling or treatment (such as cyst drainage, drug injection, etc.).
This method is commonly used to diagnose lesions in the digestive system, lungs, or other deep organs, such as tumors, cysts, lymph nodes, and other abnormalities in the pancreas, gastrointestinal tract, liver, and more. It is also used to obtain cell or tissue samples for pathological examination (e.g., tumors, cysts, inflammation, etc.).

|
General Diagnostic Use |
22G to 25G |
Thinner needles for better maneuverability and minimal discomfort. Ideal for sampling from the stomach, liver, or pancreas. |
|
Tumor Biopsy |
19G to 22G |
Thicker needles with cutting edge to handle denser, fibrous tissues like pancreatic tumors or liver masses, ensuring reliable tissue acquisition. |
|
Cyst or Abscess Aspiration |
19G to 21G |
Needles with a wider lumen to facilitate fluid aspiration from larger cysts or abscesses. Ideal for precise targeting of fluid-filled cavities. |
|
Lymph Node Biopsy |
22G to 25G |
Thinner needles for fine tissue sampling from small or deep-seated lymph nodes, ensure minimal tissue disruption. |
|
Liver or Other Organ Sampling |
19G to 22G |
Slightly thicker needles for liver or similar organ biopsies, offering strength to reach deeper tissues and ensuring effective sample collection. |

EUS Guided Fine Needles are typically made from materials such as cobalt-chromium (Co-Cr), medical-grade stainless steel (304, 316L), nitinol, or titanium alloys. We select medical-grade stainless steel and nitinol as core materials to ensure excellent strength, flexibility, and corrosion resistance, all while meeting ISO 10993 and FDA biocompatibility standards.
We offer various needle tip designs (such as reverse cutting and side-hole needles) and needle sizes (19G, 20G, 22G, 25G) to meet different lesion types and clinical needs.
- Reverse Cutting Needle: Features a reverse cutting slot at the tip, allowing for easier tissue cutting during insertion.
- Side-Hole Needle: Equipped with a side hole at the tip, facilitating tissue entry into the needle cavity.
- Grasping Needle: Designed with a grasping mechanism to actively capture tissue.
Common needle sizes include 19G, 20G, and 22G. Larger sizes (e.g., 19G) are ideal for obtaining larger tissue samples but are more difficult to handle, while smaller sizes (e.g., 22G) are better suited for fragile or vascular-rich lesions. Our needle tips or bodies come with platinum imaging markers to assist in positioning under ultrasound or X-ray.
At Manners Technology, we provide full material certifications for every component of the EUS Guided Fine Needle. Using micron-level precision machining, we ensure uniformity in the needle body and sharpness at the tip, minimizing tissue damage and improving sampling success rates. Please note that these needles are custom products, not off-the-shelf items. Manners specializes in providing tailored solutions to meet your specific requirements. Contact us for custom orders and expert support.

EUS Guided Fine Needle Manufacturing Process
1. Material Selection and Testing
- We use medical-grade stainless steel or nitinol that meets ISO 10993 and FDA standards to ensure high strength, corrosion resistance, and biocompatibility.
- Raw materials undergo rigorous chemical composition and physical property testing to ensure compliance with industry standards.
2. Needle Body Forming and Machining
- Using precision drawing technology, we shape the material into a slender needle body, ensuring uniform diameter (tolerance controlled within ±0.01mm).
- CNC machining or laser processing technologies are employed to cut the needle body to the required length and shape the needle tip into specific designs (such as bevel, reverse cutting slots, or side-hole designs).
3. Surface Treatment and Functional Coatings
- The needle body undergoes high-precision polishing to minimize surface roughness, reduce tissue damage, and improve puncture efficiency.
- A PTFE (polytetrafluoroethylene) or other functional coating is applied to reduce friction and enhance durability.
4. Imaging Markings and Customization
- At the customer's request, platinum or gold coatings are applied to specific areas of the needle tip or body as imaging markers for clear visibility under ultrasound or X-ray.
- High-precision laser engraving technology is used to mark specifications, branding, or other custom information on the needle body.
5. Quality Inspection and Performance Testing
- Each needle undergoes thorough quality inspection to ensure the diameter, length, and needle tip shape meet design specifications.
- Puncture force tests, flexibility tests, and imaging effect verification ensure that the product performs to clinical standards.
6. Packaging and Delivery
- Each needle is individually packaged in a PP bag to ensure sterility and moisture resistance.
- Customized packaging options are available based on customer requirements to meet specific needs.
