The acupuncture needles have a diameter of 0.25mm, 0.30mm, 0.35mm, etc., and a length of 1 inch, 1.5 inch, 2 inch, 2.5 inch, 3 inch, etc. For different acupoints and different therapeutic purposes, acupuncture needles of different lengths and thicknesses need to be selected. During the operation, the doctor needs to follow the principle of asepsis, disinfect the injection site, and master the correct injection Angle and depth to avoid damage to blood vessels and nerves.
The material of acupuncture needles is generally stainless steel, because stainless steel has high strength and toughness, and is not easy to break and bend. At the same time, stainless steel also has good corrosion resistance, which can ensure the safety and durability of acupuncture needles.
