Description
What Is An EUS FNA Nitinol Needle?
The EUS FNA Nitinol Needle is a medical device specifically designed for diagnostic and therapeutic procedures under endoscopic ultrasound (EUS) guidance. These needles play a crucial role in the diagnosis and treatment of lesions in areas such as the pancreas, gastrointestinal tract, and mediastinum.
Nitinol is a shape-memory alloy made of nickel and titanium. This alloy can return to its original shape after being deformed by external forces. It is ideal for medical instruments (such as EUS needles) that require repeated bending and deformation, maintaining flexibility in complex endoscopic passages.
Manners Technology, headquartered in Shenzhen, China, is a leading OEM manufacturer of medical devices, specializing in the research and production of EUS FNA Nitinol Needles. We offer a variety of needle tip designs (such as reverse-cutting needles and side-hole needles) and sizes (19G, 20G, 22G, 25G) to meet the diverse needs of different lesions and clinical requirements. With advanced manufacturing processes, strict quality control, and flexible customization capabilities, we are committed to providing high-performance, reliable 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. 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. For lesions requiring high-quality tissue samples, coarser needles, such as 19G and 20G, are preferred.

Applications of EUS FNA Nitinol Needle
The EUS FNA Nitinol Needle combines endoscopic technology and ultrasound imaging to provide high-resolution, real-time images of lesions in the digestive tract and surrounding organs. The fine needle is inserted through the working channel of the endoscope and, under ultrasound guidance, precisely passes through the digestive tract wall to reach the target area for sampling or therapeutic procedures, such as cyst drainage or drug injection.
This method is widely used for the diagnosis of lesions in the digestive system, lungs, and other deep organs, including tumors, cysts, lymphadenopathy, as well as abnormalities in the pancreas, gastrointestinal tract, liver, and other areas. It is also used to obtain cell or tissue samples for pathological examination, assisting in the diagnosis of tumors, cysts, inflammation, and other diseases.

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. |
