Abstract

The invention discloses an acupuncture needle. The acupuncture needle comprises a needle point, a needle body and a needle handle, wherein the needle point is integrally connected to the front end of the needle body, the rear end of the needle body is fixedly nested in the needle handle, the needle point and the needle body are made from a stainless-steel material, and the needle handle is made from a macromolecular material. The macromolecular material is prepared from the following ingredients in parts by weight: 70-80 parts of polyethylene, 20-30 parts of polymethyl methacrylate, 5-10 parts of photostabilizer, 3-8 parts of glass fibers, 5-15 parts of filler and 5-10 parts of dispersant, wherein the photostabilizer contains nano-titania and nano zinc oxide which are in the weight ratio of 1: (0.5 to 2), and the filler contains nano calcium carbonate and nano-silica which are in the weight ratio of 1: (2 to 5). The acupuncture needle has the beneficial effects that the needle handle of the acupuncture needle has good oxidation resistance.

Description

technical field [0001] The invention relates to a medical device, in particular to an acupuncture needle. Background technique [0002] Acupuncture is an important part of traditional Chinese medicine. Acupuncture needles in acupuncture are an important tool for doctors to treat diseases. Under the guidance of TCM theory, doctors insert acupuncture needles into the patient's body at a certain angle, and use acupuncture techniques such as twisting and lifting to stimulate specific parts of the human body to achieve disease treatment. [0003] Acupuncture needles in the prior art generally include a needle point, a needle body and a needle handle. And the making material of needle point and needle body also basically adopts stainless steel. However, the material of the needle handle has more changes. According to the material of the needle handle, acupuncture needles include various metal handle needles such as copper wire winding handle needles, stainless steel handle nee...
