The needle core consists of a stainless steel needle and a hard-plastic core, as shown in **Figure 2**. This part insures the FSN acupuncture needle to reach enough rigidity to enter the body quickly and to complete sweeping movement. The stainless steel needle tip is beveled. On the base, there are 10 protuberances which are on one side. When the convex protuberances are upward, the beveled tip of the needle is also upward. The surface is in line with the tip of the needle, the front end of the needle has a longitudinal groove, and the front of the groove has a transverse slot on the right side, which is used for fixing the soft casting tube during performing a sweeping movement.

The soft casting tube covers the stainless steel needle (steel needle inside, soft casting tube outside). The soft casting tube is fixed to the plastic socket through the built-in rivets, as shown in **Figure 2**. The casting tube of FSN acupuncture needle has a bump, which is matched with the grooves in the core seat and the slot. The protuberances on the base are placed at the bottom of the groove when we sweep the needle.

a.The tube and the core are anastomosed into one, which is conductive to the stability of the insertion, as well as to the needle manipulation and the sweep-

b.When performing sweeping movement, the stainless steel needle tip is fully retreated into the soft tube; it can prevent the tingling caused by injuring the

c.Because of its sufficient softness, the tube which will not affect normal activities of patients can be kept under the skin for several hours after the treatment,

To protect the stainless steel needle and soft tube from the impact of the collision, we designed a protective sheath. The protective sheath is used to protect the aseptic state, as shown in **Figure 2**. After the sweeping movement, the solid needle

and it will not puncture blood vessels and other tissues.

The insertion points are chosen according to the following principles:

insertion points are better to be far away for big area and more TMs.

a.In most cases, insertion points are chosen nearby TM. It can be inserted 3–5 cm

b.Insertion points are better to be nearby TMs for small area and less TMs, while

c.From far to near, if there are several TMs, such as chronic cervical and lumbar pain, which is usually accompanied by abnormalities of the upper limbs and lower limbs, the insertion points should be chosen from far to near, rather than the opposite.

The FSN inserting device and FSN acupuncture needle should be in accordance with the regulations of national medical device production and sales supervision. In order to prevent needling accidents, the disposable FSN acupuncture needle should be strictly inspected each time before use. If any unqualified conditions such as

FSN inserting device is a device specifically designed for the inserting of FSN acupuncture needle, which is developed by Nanjing FSN Medical Co., Ltd. It is convenient for the therapist to deliver the needle. It can not only reduce the pain of needle insertion but also ensure the accuracy and safety of the needling. The device consists of four parts, the base, the control button, the needle drive rod, and the
