Background

Acupuncture is a medical technique originated in china and has been used in china for over 2500 years. The filiform needle is a common medical instrument for implementing acupuncture and moxibustion therapy, and is composed of a needle body and a needle handle, and for two thousand years or more, the traditional Chinese medicine directly pinches the filiform needle with hands to penetrate into the acupuncture point for therapy, and the aseptic technique operation of filiform needle therapy is not well solved. Although acupuncture points are sterilized before filiform needle treatment, the filiform needles used also require autoclaving or the use of disposable sterile filiform needles;

however, since the filiform needle is slender and soft, the skin is often not penetrated by gripping the needle shaft. When a long filiform needle is used, i.e. a needle body of 75mm (3 inches) to 200mm (8 inches), the needle is difficult to insert by holding the needle handle, and the operator's hand often touches the needle body during actual work. The common needle holding mode is a pen holding mode, namely, a thumb and a forefinger of a stabbing hand hold a needle handle, and the middle finger pulp props against the lower end of a needle body to insert a needle; sometimes, the other hand is used to hold the needle body for needle insertion. Therefore, the filiform needle inserted into human tissue inevitably contacts the hand of an operator to cause pollution, the aseptic technique operation principle is not met, medical workers need to repeatedly and manually clamp the filiform needle and then insert the skin, time and labor are wasted, and the novel filiform needle holding and inserting device is provided.
