FNA Needle and FNB Needles

The FNA (fine needle aspiration) and FNB (fine needle biopsy) needles are minimally invasive medical technology tools. The FNA needle consists of a slender puncture needle used to quickly collect cell or tissue samples for cytological analysis. The FNB needle contains a cutting edge, which can obtain larger living tissue samples, provide more detailed tissue structure information, and contribute to more accurate pathological diagnosis. Manners Technology focuses on excellent FNA and FNB Needle manufacturing, using high standards and advanced equipment to ensure the highest quality performance of each needle.

Categories

The FNA needle (Fine Needle Aspiration Needle) is a very fine puncture needle specially designed for cytological analysis. With a small diameter and sharp tip, the needle can pass through tissue and extract samples in extremely fine forms. Its distinguishing feature is that it is quick and easy to operate, and it can quickly provide confirmed results through cytological analysis. The tip of the FNA needle is designed to minimize patient discomfort, providing convenient support for early diagnosis in the medical field.

Compared with the FNA needle, the tip of the FNB needle (Fine Needle Biopsy Needle) is sharper, ensuring that richer tissue samples are obtained during the puncture process. Although it is similar to an FNA needle in that it is a slender metal tube, it is usually slightly larger in diameter to accommodate larger tissue. The main difference from FNA is that it is equipped with a cutting device, allowing doctors to cut and retain a larger tissue sample during puncture. Therefore, the FNB needle focuses on obtaining more tissue information, especially when it comes to deep detection of different tissue levels.

These two fine needles are crucial for the study of pathologies such as cancer and tumors, and provide key support for early diagnosis and treatment.

Applications

FNA (fine needle aspiration) needles and FNB (fine needle biopsy) needles are key tools commonly used in the medical field for tissue collection. Especially in cytology and pathology, it plays an irreplaceable role. Its fine needle design allows it to enter hard-to-reach areas of the body and complete high-precision tissue collection. The elongated shape is designed to accommodate tools such as endoscopes or ultrasound guidance, allowing doctors to precisely locate and collect target tissue.

From a specific application point of view, the FNA needle (Fine Needle Aspiration Needle) provides a method to extract cell samples from suspicious tumors for cytological analysis to help doctors evaluate the benign or malignant nature of the tumor. Likewise, it can also be used for cytological evaluation of lymph nodes, which is important for diagnosing or excluding lymph node disease. In addition, the FNA needle also plays an important role in cyst aspiration, guiding the puncture and withdrawing samples within the fluid cyst.

Relatively speaking, FNB needle (Fine Needle Biopsy Needle) is more widely used. First, it can obtain small pieces of tissue from suspected diseased tissue through puncture and perform tissue biopsy for detailed histological analysis. Secondly, FNB needles play a role in helping doctors identify difficult cases, providing more comprehensive tissue information and helping to clarify the nature of the lesion and final diagnosis. In some special cases, such as when dealing with larger, more solid lesions, the FNB needle may be more suitable to obtain a more representative tissue sample. This versatility makes the FNB needle an important tool in clinical practice, capable of more comprehensively supporting physicians in diagnostic and treatment decisions.

Manufacturing

The design and manufacturing of these two types of needles require a rigorous process to ensure their accuracy, controllability and safety. Manners Technology specializes in exquisite manufacturing to provide doctors with excellent FNA and FNB Needles to ensure the accuracy of diagnosis and treatment.When manufacturing FNA needles and FNB needles, Manners Technology follows a series of highly precise machining process steps to ensure product quality and reliability. First, we choose medical-grade stainless steel, which provides enough hardness and corrosion resistance to keep the needle stable during use. After the material is selected, engineers perform CAD modeling based on the customer’s drawings, taking into account the different shapes and characteristics of the two needles.

Manners uses a high-precision laser cutting process to cut the material into the required shape according to the CAD design. Among them, the FNA Needle focuses on providing highly precise collection of cell and tissue samples. It usually adopts a triangular cutting design and needs to be cut with a high-precision CNC machine tool to ensure the design angle and sharpness of its puncture tip. The FNB Needle focuses on deep detection of different tissue layers, and its design may include a groove or cutting edge to help collect larger tissue samples. This design allows doctors to cut tissue during puncture and retain it within the needle to obtain more tissue information, which is also laser cut and grooved by high-precision CNC machines.

Both FNA and FNB needles will undergo surface treatment and special tip treatment to ensure that potential discomfort and tissue damage are minimized during operation. Manners professionally grinds and polishes the needle tips through processes such as grinding, acid etching, and electrolytic polishing. This is especially important for FNA needles and FNB needles, which need to easily penetrate tissue in minimally invasive procedures. These treatments help improve the surface smoothness of the needle, ensure sharpness of the needle tip, reduce the risk of irritation and injury, and enhance the overall appearance of the product.

All these process and design efforts are aimed at providing medical professionals with excellent and reliable tools. Through these manufacturing processes, Manners Technology is committed to providing precise and controllable FNA needles and FNB needles to the medical field, thereby supporting Doctors perform more accurate and safe cell or tissue collection.
