FAQ:

Question: What is the practical function of the "sandblasted" treatment on the needle tube surface?

Answer:​ The sandblasting treatment mainly creates a uniform matte anti-slip layer on the metal surface. In medical operations, this effectively increases the friction between the fingers and the needle tube, especially when wearing medical gloves. It prevents the needle body from rotating or slipping, providing doctors with a more stable handfeel and stronger control during fine injections.

Question: Why choose a side-hole instead of a traditional bevel cut? What are the benefits of the side-hole?

Answer:​ The biggest advantage of the side-hole design is its superior hydrodynamic performance. Liquid flows out horizontally from the side wall, providing good directionality and preventing jet flow, which effectively reduces the physical impact on blood vessels or target tissues. Additionally, the side-hole can reduce the probability of tissue clogging the needle tip to some extent, making the infusion process smoother.

Question: Which specific medical departments or surgeries is this type of needle mainly suitable for?

Answer:​ Due to its fine tip and side-hole design, it is ideal for fields requiring extremely high precision, such as: micro-injections of hyaluronic acid or drugs in ophthalmic surgery, local filling in plastic and cosmetic surgery, root canal irrigation in dentistry, and minimally invasive treatments in dermatology.
