The overall structural composition 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 set with a needle handle. The surface of the needle body and tip is smooth, while the needle handle has threads. This design is intended to facilitate the doctor's operations such as lifting, thrusting, twisting and turning during use, and to enhance the stimulation effect on the acupoints.
