How To Deal With Puncture Needles And Thread Embedding?

How to deal with puncture needles and thread embedding?

1. Needle embedding method:

Routinely disinfect the local skin. Take a piece of sterilized sheep’s gut about 1 to 2 cm in length with forceps, place it on the front end of the lumbar puncture needle tube, and then connect the needle core, tighten the thumb and index finger of the left hand or lift the skin of the needle, and hold it in the right hand. The needle is pierced to the required depth. When the needle feel appears, push the needle core while withdrawing the needle tube, bury the catgut in the subcutaneous tissue or muscle layer of the acupoint, and cover the needle hole with sterile gauze. The needle of No. 9 injection needle can also be used as a cannula, and the needle of a 28-gauge 2-inch long needle can be cut to make the needle core. Put 1 to 1.5 cm of No. 00 catgut into the needle to bury the acupuncture points. The operation method is the same as before. Use special When the embedding needle is used for embedding, after disinfecting the local skin, use 0.5-1% procaine hydrochloride as infiltration anesthesia, cut a section of catgut (about 1 cm long), and put it on the notch of the embedding needle tip, at both ends Clamp the needle with vascular forceps, hold the needle in the right hand and the forceps in the left hand, and pierce the needle tip in a direction of 15°～40° downwards. When the needle is completely buried under the skin, insert the needle 0.5 cm, and then withdraw the needle. Use a cotton ball or Press the gauze against the pinhole for a while, and then cover the wound with gauze.

2. Cutting and embedding method:

Use 0.5% procaine hydrochloride as an infiltration anesthesia on the selected acupoints. Use the tip of a knife to cut the skin (0.5-1 cm). First, insert the vascular forceps into the acupuncture point and then reach the muscle layer through the superficial fascia. Massage the sour points for a few seconds, rest for 1 to 2 minutes, and then bury 4 to 5 catgut in the muscle layer with 0.5 to 1 cm long catgut. The catgut should not be buried in the fat layer or too shallow to prevent it from being easily absorbed. Or infection, the incision is sutured with silk thread, covered with sterile gauze, and the silk thread is removed after 5-7 days. For embedding, acupuncture points with relatively full muscles are mostly used. The waist and waist points are most commonly used. The principle of selecting acupoints is the same as that of acupuncture, but the selection of acupoints should be simplified. Embedding sutures at 1 to 3 points each time can be treated once every 2 to 4 weeks.

3. Triangular needle embedding method:

Use gentian violet to mark the points of needle entry and exit at a distance of 1 to 2 cm from both sides of the acupuncture point. After the skin is disinfected, 0.5-1% procaine hydrochloride is used for intradermal anesthesia at the marked place. The skin suture needle with catgut is clamped with a needle holder, and inserted from one local anesthetic point through the acupuncture point The lower subcutaneous tissue or muscle layer is penetrated from the opposite local anesthesia point. Pinch the skin between the two pinholes and stick to the skin. Cut the threads at both ends, relax the skin, gently rub the local area, so that the gut is completely buried under the skin. In the tissue, gauze is covered for 3 to 5 days, 1 to 3 acupoints can be used each time, and thread embedding is generally used once in 20 to 30 days.
