Description
What Is An Endoscopic Ultrasound Fine Needle?
Endoscopic Ultrasound Fine Needle (EUS Fine Needle) is a minimally invasive diagnostic and therapeutic tool used under the guidance of endoscopic ultrasound (EUS). It combines endoscopic technology and ultrasound imaging to precisely target lesion areas in real-time, allowing for accurate sampling of cells or tissues, or for performing interventional treatments.
It is primarily used to obtain cell or tissue samples for pathological examination (such as for tumors, cysts, inflammation, etc.) or for interventional treatments like cyst drainage or drug injection. Manners Technology, located in Shenzhen, China, is a leading OEM manufacturer of medical devices, specializing in the research and production of Endoscopic Ultrasound Fine Needles. We offer a variety of needle tip designs (such as reverse-cutting needles and side-hole needles) and sizes (19G-25G) to meet various clinical requirements.

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, minimizing tissue damage and reducing the risk of bleeding.
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 the ideal choice, as they provide more complete tissue samples for pathological analysis and molecular diagnosis.

Applications of Endoscopic Ultrasound Fine Needle
Endoscopic Ultrasound Fine Needle (EUS Fine Needle) is a minimally invasive medical tool that combines endoscopic and ultrasound technologies. It is widely used in the diagnosis and treatment of deep lesions in the digestive system (such as pancreatic cancer and gastrointestinal tumors), respiratory system (such as mediastinal lymph nodes and lung cancer), and other deep lesions (such as retroperitoneal tumors and adrenal gland conditions).
It not only enables precise collection of cell or tissue samples for pathological analysis and molecular testing, but also supports interventional treatments such as cyst drainage and drug injection. With its high precision, minimally invasive nature, and multifunctionality, the EUS Fine Needle has become an indispensable technology in modern medicine, offering patients safer and more effective diagnostic and treatment options.

Endoscopic Ultrasound Fine Needle is designed with high precision, featuring a small needle diameter (19G-25G), making it suitable for minimally invasive procedures. The needle tip design is versatile (such as beveled, reverse cutting slot, side holes, etc.), significantly improving sample collection efficiency. The needle tip or body is equipped with a visibility marker (such as a platinum coating), allowing for precise location under ultrasound or X-ray guidance. The needle is made from alloys such as cobalt-chromium (Co-Cr), medical-grade stainless steel (304, 316L), nitinol, and titanium alloys, offering high strength, corrosion resistance, and flexibility, while also meeting ISO 10993 and FDA biocompatibility standards. The surface is coated with materials like polytetrafluoroethylene (PTFE) to reduce friction and minimize tissue damage. This needle supports both diagnostic purposes (such as cell or tissue sampling) and therapeutic applications (such as cyst drainage and drug injection), making it highly versatile.

Endoscopic Ultrasound Fine Needle Manufacturing Process
1. Material Selection and Quality Testing: We use medical-grade stainless steel or Nitinol that complies with ISO 10993 and FDA standards. The selected materials are rigorously tested for chemical composition and physical properties to ensure optimal quality and biocompatibility.
2. Needle Body Formation and Precision Machining: With the aid of precision drawing techniques and advanced machining, we form the materials into fine needle bodies, ensuring the needle tip is shaped with micron-level accuracy to meet exacting specifications.
3. Surface Treatment and Coating Application: The needle body undergoes detailed polishing to minimize surface roughness, and a functional coating, such as Polytetrafluoroethylene (PTFE), is applied to reduce friction and enhance the needle's lifespan.
4. Imaging Markers and Personalized Features: Imaging markers, like platinum or gold coatings, are applied to specific parts of the needle tip or body to enable accurate positioning under ultrasound or X-ray. Additionally, laser engraving technology is employed for custom markings such as size and branding.
5. Quality Assurance and Testing: Each needle undergoes a series of rigorous tests, including size inspection, puncture force testing, flexibility assessment, and validation of imaging markers, ensuring compliance with design specifications and clinical requirements.
6. Packaging and Safe Delivery: Each needle is individually packaged in a PP bag to maintain sterility and safeguard against moisture. We also offer customized packaging solutions to meet our customers' unique needs.
