The structural characteristics of acupuncture needles

How much do people know about the structure of acupuncture needles? Modern acupuncture needles are generally composed of the needle body, the needle tip and the needle handle. The front end of the needle body is the needle tip, and the rear end is the needle handle. The needle body and the needle tip are smooth, and the needle handle has threads, which is convenient for lifting, inserting, twisting and turning. It is also mainly equipped with a racket tube. The upper part of the racket tube is punched with spines, which can clamp the needle handle and fix the needle in the racket tube. Moreover, the surface of the tube is colored with codes, and different colors represent different specifications. This enables doctors to easily distinguish them and avoid usage errors. Understanding these structural features of acupuncture needles can help us better recognize this traditional treatment tool and also facilitate safe use.
