Description
What Is An EUS Access Needle?
The EUS Access Needle is a specialized medical tool used in both diagnostic and therapeutic procedures guided by Endoscopic Ultrasound (EUS). This category includes EUS FNA (Fine Needle Aspiration) needles, EUS FNB (Fine Needle Biopsy) needles, and other specialized needles for specific tasks such as cyst drainage and drug injections. These needles are essential in diagnosing and treating lesions in the pancreas, gastrointestinal tract, and mediastinum.
Based in Shenzhen, China, Shenzhen Manners Technology is a leading OEM manufacturer of medical devices, with a focus on the research and production of EUS Access Needles. We offer a broad selection of needle tip designs, such as reverse cutting and side-hole needles, as well as various sizes, including 19G, 20G, 22G, and 25G, to meet the diverse needs of different lesion types and clinical requirements. With our state-of-the-art manufacturing processes, strict quality control standards, and flexible customization capabilities, we are committed to providing high-performance EUS needle solutions to our global clients.
Comparison of EUS FNB vs. EUS FNA
EUS FNA (Fine Needle Aspiration) is mainly used to collect cell samples for cytological analysis. Finer needles, such as 22G and 25G, are particularly suitable for delicate or highly vascular lesions. On the other hand, EUS FNB (Fine Needle Biopsy) is used to obtain tissue cores for histological evaluation and molecular testing. Coarser needle sizes, like 19G and 20G, are preferred for lesions that require high-quality tissue samples.

Applications of EUS Access Needle
The EUS Access Needle integrates both endoscopy and ultrasound technology to offer high-resolution imaging of lesions within the digestive tract and nearby organs. The fine needle is introduced through the working channel of the endoscope and, under ultrasound guidance, is carefully maneuvered through the digestive tract wall to reach the targeted area for sampling or treatment, such as cyst drainage or drug delivery.
This method is frequently used to diagnose lesions in the digestive system, lungs, and other deep organs, including tumors, cysts, lymph nodes, and abnormalities in the pancreas, gastrointestinal tract, liver, and more. It is also used to obtain cell or tissue samples for pathological examination, such as for tumors, cysts, inflammation, and various other conditions.

Description |
|
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 Access Needles are primarily constructed from high-quality materials such as cobalt-chromium (Co-Cr), medical-grade stainless steel (304, 316L), nitinol, or titanium alloys. We specifically choose medical-grade stainless steel and nitinol for their superior strength, flexibility, and corrosion resistance, while ensuring compliance with ISO 10993 and FDA biocompatibility standards.
We offer a wide range of needle tip designs (including reverse-cutting and side-hole needles) and sizes (19G, 20G, 22G, 25G) to accommodate various lesion types and clinical needs.
- Reverse-cutting needle: The tip is designed with a reverse-cutting slot to facilitate easier tissue cutting during insertion.
- Side-hole needle: The tip includes a side hole to allow tissue to enter the needle lumen more effectively.
- Grasping needle: Features a mechanism that actively captures and secures tissue.
Common needle sizes are 19G, 20G, and 22G. Larger sizes, such as 19G, are ideal for obtaining larger tissue samples but may be more difficult to handle. Smaller sizes, like 22G, are perfect for fragile or highly vascular lesions. Additionally, our needles are equipped with platinum imaging markers on the tip or shaft, aiding in precise positioning under ultrasound or X-ray guidance.
At Manners Technology, we provide comprehensive material certifications for each component of the EUS Access Needle. Through micron-level precision machining, we ensure consistency in the needle shaft and sharpness of the tip, minimizing tissue damage and enhancing the success rate of sampling. Please note that these needles are custom-made to order, not mass-produced. Manners specializes in delivering personalized solutions tailored to your specific needs. Contact us for custom orders and expert support.
