Medical Needle & Cannula Manufacturer
Medical Needle & Cannula Manufacturer
Medical needles are precision-engineered devices designed for specific diagnostic, therapeutic, and minimally invasive procedures. These needles serve critical roles across various medical fields, including vascular access, biopsy collection, cosmetic injections, dialysis, and reproductive medicine.
Key types include: Biopsy needles, Biopsy needle, IV Catheter cannula (Indwelling needle), Beauty needle (Cosmetic needle), Fistula Needle, Subcutaneous injection needle (Subcutaneous tunnel needle), Egg retrieval needle (ovum pick up needle), Infusion needle, Coaxial needle, Insulin needle, Special-Shaped needle, and Irregular needle knife.
Manufactured under strict ISO/FDA standards, these single-use, sterile needles prioritize patient safety, sharpness, and procedural efficacy. Advances in material science (e.g., ultra-thin walls, echogenic coatings) enhance ultrasound visibility and reduce trauma.
Applications span hospitals, clinics, and aesthetic centers, with growing demand in personalized medicine. Customizable lengths, gauges, and tip designs cater to specialized interventions, underscoring their versatility in modern healthcare.

Question & Answer
What is a fistula needle used for?
The primary function of fistula needles is to facilitate blood flow from the patient’s body to the dialysis machine and vice versa. The AV fistula needle is inserted into the fistula, and blood is drawn into the dialysis machine, where it undergoes filtration to remove waste products and excess fluid.
What is the best needle to use for microneedling?
The most used facial needle sizes are 0.5mm and 1mm. Both of these sizes are suitable for most areas of the face and can be used for almost any skin issue. Since in-home skin needling began, the robust needle depth of 0.5mm has been the number one selling needle size.
What needle is used for nerve block?
Nerve blocks use specialized needles, often designed with an echogenic tip for visibility with ultrasound guidance, a bevel (like a Quincke or Coudé) for precision, and sometimes depth markings. Many are insulated and used with a nerve stimulator to help locate the correct nerve. Needles vary in length, gauge (e.g., 21-27 gauge), and features like directional injection ports.
What size needle is used for coaxial biopsy?
It is usually obtained as a set. For example, it may be a combination of a 17G outer guiding needle that comes with its own stylet and an 18G biopsy needle. The commonly available lengths are 9 and 15 cm.
What kind of needle is used for egg retrieval?
Traditionally, 19-gauge needles have typically been used for egg retrieval procedures in IVF treatments. However, smaller needles offer significant benefits as they reduce the risk of puncturing follicles.
What is an indwelling needle?
An indwelling needle used for infusion or the like ordinarily has a double-needle structure composed of an outer needle and an inner needle. Upon its use, the indwelling needle is pierced into a blood vessel in a state where the inner needle is positioned in a lumen of the outer needle.
What is the name of the needle used for infusion?
A butterfly needle is a device that your healthcare provider may use to draw blood from your vein. They also use it to deliver fluids or medications into your veins. It’s also known as a winged infusion set or a scalp vein set. It gets its name from the two butterfly “wings” on either side of the needle.
What needle is used for insulin?
Insulin is administered with small, fine needles, typically ranging from 32 to 29 gauge and 4 to 12 mm (or 5/32to 1/2 inch) in length, depending on your body type and the injection site. The specific needle size is chosen based on a doctor’s recommendation to ensure the insulin is injected into the subcutaneous tissue and not the muscle, with 4mm needles being effective for most adults.
