Millimeter Needle Holder

technical field

The utility model relates to a medical device, in particular to a needle-holding needle-inserting device for filiform needles meeting the operation requirements of aseptic technology. the

Background technique

Acupuncture is a medical technique that originated in China and has been used in China for more than 2,500 years. Today, as a simple and effective treatment method, acupuncture is still widely used clinically, and as a natural green therapy, acupuncture has become popular all over the world. The filiform needle is the main tool for acupuncture treatment, and it is the most widely used clinically. The filiform needle is a commonly used medical device for acupuncture and moxibustion. The filiform needle is composed of the needle body and the needle handle. For more than two thousand years, Chinese medicine practitioners have directly held the filiform needle by hand and inserted it into the acupoints for treatment. The filiform needle is sterile Technical operations have not been well resolved. Although acupuncture points are sterilized before treatment with filiform needles, the filiform needles also require high-pressure steam sterilization or the use of disposable sterile filiform needles. However, because the filiform needles are slender and soft, they often cannot penetrate the skin by only holding the needle handle. When performing filiform needle therapy, if you use a longer filiform needle, that is, a needle body length of 75 mm (3 inches) to 200 mm (8 inches), it is difficult to pinch the handle of the filiform needle and insert the needle. In actual work, the operator's hand often touches the needle. body. The commonly used way of holding the needle is the pen-holding style, that is, the thumb and index finger of the pricking hand pinch the needle handle, and the middle finger pad presses against the lower end of the needle body to insert the needle; sometimes the other hand is used to hold the needle body and insert the needle. Like this, because the filiform needle that punctures human tissue inevitably touches operator's hand and is polluted, does not accord with the principle of aseptic technique operation. Due to the increase in blood-borne disease infections, the number of iatrogenic infections is also on the rise. Improving acupuncture and moxibustion instruments and operating methods has become an urgent problem to be solved in hospital infection management. Under this background, many people try to invent instruments to improve it, such as the Chinese patent documents of Patent No. 01253412.9; 200520011932.2 and 200620006248.X and 201020235074.0, all invented the filiform needle clamping needle inserter respectively. But the results are not very satisfactory, especially do not meet the simple and practical characteristics of filiform needle therapy and the requirements of aseptic technique operation. Because it is rare to take only one acupuncture point for treatment clinically, dozens of acupuncture points are needed to treat a patient at most. If multiple acupoints are treated with the utility model of these inventions, the operator must hold the needle inserter with a hand-held filiform needle to maintain sterility and not be polluted after the first acupuncture point is inserted. It is very difficult to select and fix acupoints, disinfect the skin, and take out the filiform needle with only one hand, especially it is very difficult to take out the disposable sterile filiform needle from the packaging bag (or slot plate) with one hand without being contaminated. Therefore need to invent safer filiform needle holding needle insertion instrument. the

Invention content:

The purpose of this utility model is to provide a filiform needle holding and inserting device for overcoming the above-mentioned defects.

The needle-holding needle inserter described in the utility model is composed of two left and right clamping arms that are identical in structure, size, shape, and material. The force-applying part of the needle end is wide, and the inner surface of the needle-holding part of the needle-holding end is designed with a grid pattern, and the tails of the clamping arms at the handle end are connected, and the angle between the two clamping arms is less than 40 degrees, thereby forming an elastic clamp. the

The needle-holding and inserting device for filiform needles described in the utility model can be made of polystyrene resin or ABS plastic or other materials with certain elasticity. The disposable filiform needle-holding and needle-introducing device is packaged and sterilized at low temperature for use. the

The needle-holding needle-inserting device described in the utility model can be made of stainless steel at one time, and can be used after being sterilized by high-pressure steam. the

In clinical use, after selecting acupoints on the patient's body, the skin is routinely disinfected. Hold the utility model close to the handle of the elastic joint and take out the utility model, and put it on a clean and flat table. Open the package and take out the sterile needle with the handle of the needle in the left hand, hold the force-applied part of the needle holder of the utility model with the mother finger and index finger of the right hand, and clamp the needle body of the needle holder with the needle tip of the needle holder of the utility model part, quickly puncture into the acupuncture points. After using the filiform needle holder of the utility model to continue puncturing the filiform needle into a certain depth according to the needle insertion direction as required, the utility model filiform needle holder is placed on a clean and flat table. If you need to puncture other acupoints, repeat the above method and continue to use the filiform needle holder of the present utility model to puncture and insert needles for treatment. After all acupoints are punctured, acupuncture techniques and needle retention are performed as needed. During the whole treatment process, when holding the needle holder of the present utility model for puncturing and placing it on a clean and flat table, it should be ensured that the needle-holding part of the needle holder of the present utility model remains sterile and not polluted. The sterile filiform needle and the sterile area of the acupoints remain sterile and not contaminated. Every filiform needle holder of the present utility model can only be used on one patient no matter how many acupuncture points are treated. The disposable needle holder of the utility model can only be used on one patient; if the needle holder of the utility model is made of stainless steel, it needs to be sterilized by pressure steam before it can be used, and once it is opened or used and polluted, Must be autoclaved before re-use by another patient. the

After using the utility model of the present invention to complete acupuncture at an acupoint, put the utility model of the present invention on a clean and flat table, such as a treatment tray, operating table, bedside table, etc., because the design of the utility model makes the needle-holding part far away from the table. polluted. Therefore, the operator can easily select and fix acupoints with both hands, disinfect the skin, take out the filiform needle, and then hold the filiform needle with the utility model of the present invention for puncturing. the

The utility model has the advantages of simple structure, strong grip, great elasticity, convenient use, hygiene and safety. the
