FAQ:

Question: What are the advantages of the "3 equal cutting edges" design compared to ordinary bevel needles?

Answer:​ Ordinary bevel needles rely on single-point sharpness for penetration, which can easily cause significant tissue tearing. In contrast, our 3-equal-section cutting edge design functions, utilizing three sharp edges to perform micro-cutting simultaneously during insertion. This not only significantly reduces puncture resistance for smoother entry but also minimizes tissue compression and cutting damage, making it ideal for areas rich in blood vessels and nerves.

Question: Why is a side-hole designed near the needle tip? Does this change the direction of fluid flow?

Answer:​ The primary function of the side-hole is to relocate the fluid outlet from the tip apex to the side. In medical procedures (such as local anesthesia or irrigation), this prevents the liquid from directly impacting deep tissues vertically, which could cause excessive pressure or tissue separation. Additionally, the side-hole design allows smooth medicine delivery even when the needle tip is pressed against tissue walls, preventing tip blockage.

Question: What material is used for this needle? Does it support high-temperature sterilization for reuse?

Answer:​ We manufacture this needle using 316L medical-grade stainless steel. This material possesses exceptional hardness and corrosion resistance, fully supporting high-temperature steam sterilization (Autoclave), ethylene oxide (EO), and irradiation sterilization. Even after multiple sterilization cycles, its edge sharpness and surface finish remain uncompromised, ensuring stable performance for long-term use.

Question: Can we customize the position and size of the side-hole or the length of the needle body according to our requirements?

Answer:​ Absolutely. We offer professional OEM/ODM customization services. We can precisely adjust the outer diameter (OD), length of the needle tube, the diameter and position of the side-hole, and even the sharpness angle of the cutting edges according to your medical device design drawings, ensuring a perfect fit with your equipment.

Question: Which specific medical procedures is this side-hole needle with triple cutting edges most suitable for?

Answer:​ It is highly suitable for ophthalmic microsurgery (such as anterior chamber paracentesis), aesthetic plastic injections (such as hyaluronic acid fillers), dental local anesthesia, and various minimally invasive interventional procedures. In these scenarios, precise control over tissue trauma and accurate medicine delivery are paramount, and this product is specifically engineered to meet these stringent demands.
