SHOMEA Customized Sterilized Endoscopy Injection needle

Product Specification

Exquisite craftsmanship and excellent accuracy

The whole product is processed by CNC precision machining technology. The straightness of the needle body, thread precision, and needle tip angle are strictly controlled to ensure batch consistency, meeting the needs of high-precision medical operations.

Smooth surface and low resistance

The needle body and base surface are polished/Passivated, with low roughness, reducing liquid residue and tissue friction resistance, and improving fluid passability and operational smoothness.

Multi-scene adaptation and flexible expansion

The standardized interface and sharp-tip design are suitable for multiple medical scenarios (such as local delivery, minimally invasive puncture, sample collection, etc.). It can also be used as a substrate for customized medical components, with strong expandability.

FAQs:

Q: What is the difference between this needle and a regular straight needle? Why does it have threads and a flange?

A: Regular straight needles are mostly for free puncture, while this needle is designed for precise fixation. The threaded tail​ allows secure connection to syringes, catheters, or dedicated fixtures to prevent slipping. The flange (disc)​ in the middle acts as a stopper to ensure consistent insertion depth, preventing over-penetration and injury, mainly used for micro-volume, controlled delivery or nutritional feeding.

Q: What is the material of the needle? Is it suitable for experiments with high biocompatibility requirements?

A: This product is made of imported medical-grade stainless steel (e.g., 304/316L)​ with precision manufacturing and strict electropolishing. It features high surface finish, excellent biocompatibility, corrosion resistance, and high toughness, making it safe for rodent (rat/mouse) experiments and various biomedical micro-operations.

Q: In which fields is this type of needle mainly applied?

A: Mainly applied in life science research (e.g., animal gavage, nasogastric feeding, stereotactic micro-injection), medical device R&D, in-vitro diagnostics (IVD), and fluid control for small precision instruments.

Q: What is the side opening style and shape of the needle tip? How is the liquid flow rate ensured?

A: The tip features a micro side-opening with a beveled cut, and the edge is finely polished to be smooth without burrs. This design effectively reduces friction during tissue puncture while guiding fluid flow directionally, ensuring a stable flow rate that is less prone to bubbles or backflow, ideal for micro-perfusion sensitive to flow speed.

Q: What is the thread specification? Can it be adapted to syringes or equipment from other brands?

A: Standard threads are Metric M6 or UNF 1/4-28​ (depending on the model, please consult customer service for specifics). Our thread tolerances are strictly controlled, allowing perfect compatibility​ with most mainstream micro-syringes, Luer connectors, and custom fixtures. We recommend confirming your interface dimensions before ordering.
