Description
What Is An EUS Nitinol Needle?
The EUS Nitinol Needle is made from Nitinol, a unique material known for its superelastic and shape-memory properties. This material provides enhanced maneuverability in tortuous scope positions and ensures the needle maintains its shape for multiple passes, making it ideal for complex diagnostic and therapeutic procedures guided by Endoscopic Ultrasound (EUS).
In addition to our traditional cobalt-chromium EUS needles, Shenzhen Manners Technology, located in Shenzhen, China, now offers Nitinol-constructed EUS needles. We provide a variety of needle tip designs, such as reverse cutting and side-hole needles, in sizes ranging from 19G to 25G to meet various clinical needs. With advanced manufacturing, strict quality control, and customization options, we deliver high-performance EUS needle solutions to clients worldwide.

Comparison of EUS FNB vs. EUS FNA
EUS FNA (Fine Needle Aspiration) is primarily used to collect cell samples for cytological analysis. Smaller needles, such as 22G and 25G, are ideal for fragile or highly vascular lesions. In contrast, EUS FNB (Fine Needle Biopsy) is used to obtain tissue cores for histological examination and molecular testing. Larger needle sizes, like 19G and 20G, are preferred for lesions that require high-quality tissue samples.

Applications of EUS Nitinol Needle
The EUS Nitinol 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. |
