Description

Embedding needle capable of preventing needle core from falling off

Technical Field

The utility model relates to the technical field of thread embedding needles, in particular to a thread embedding needle capable of preventing the needle core from falling off.

Background Art

Thread embedding therapy is a long-acting acupoint stimulation therapy in traditional Chinese acupuncture. Catgut is implanted in corresponding acupoints and specific parts, and its continuous stimulation on acupoints is used to treat diseases. After the catgut stimulates the meridian acupoints, the anabolism of muscles in the body increases, while the catabolism decreases, the synthesis of myosin and carbohydrates increases, and the decomposition of lactic acid and creatine decreases, thereby improving the nutrition and metabolism of muscles. The stimulation of catgut can also improve the body's immunity, disease resistance and improve blood circulation. At present, the thread embedding needle is mainly composed of a puncture needle tube, a needle core, a large needle seat connected to the end of the puncture needle tube, and a small needle seat connected to the end of the needle core. A limited space sleeve is arranged between the mating part of the large needle seat and the small needle seat. The pre-implanted catgut is first inserted into the puncture needle tube, and then the puncture needle tube is inserted into the corresponding acupoint of the human body, and then the needle core is pushed to implant the catgut into the human body.

A Chinese patent with the publication number CN201710394U has been searched and disclosed a thread embedding needle, which is invented to solve the inconvenience in use and other problems in the prior art. The utility model is composed of a puncture needle tube, a needle core that can be inserted into the puncture needle tube, a large needle seat connected to the end of the puncture needle tube, and a small needle seat connected to the end of the needle core. A guide groove is provided in the large needle seat, and a guide body is provided on the outer wall of the small needle seat, which is adapted to the guide groove and can be inserted into the guide groove. An adjustment handle is provided outwardly at the bottom of the large needle seat. With the above structure, the adjustment handle can be held by hand when inserting the needle. The adjustment handle limits the movement of the puncture needle tube relative to the finger, which makes it easy to insert the needle, quickly inserts the needle, and reduces the pain of the needle. In addition, the depth of the needle can be adjusted in advance, which is flexible and safe.

However, the needle core of this type of thread embedding needle often falls off from the needle body; sometimes when the needle is inserted vertically, the needle core pushes the thread body out of the needle body due to its own weight. This phenomenon of the needle core being uncontrolled can easily lead to waste and pollution of medical equipment during treatment.

Utility Model Content

In view of the shortcomings of the prior art, the utility model provides a thread embedding needle that prevents the needle core from falling off. The utility model has the advantages that the needle core and the connecting seat are connected by a bellows, so that the needle core can be controlled, effectively preventing the needle core from falling off, reducing the phenomenon of the needle core falling off during clinical treatment, avoiding pollution and waste of medical instruments, and the needle tip of the thread embedding needle is designed as a blunt head with a cutting edge, and the needle head is similar to a hollow hemisphere in the shape of a spoon, so that it is easy to break when used, and can avoid damaging blood vessels, nerves, glands and other subcutaneous tissues.

One side of the needle handle 4 is detachably connected with a bellows 5, and the other side of the bellows 5 is fixedly connected to the connecting seat 1.

In this embodiment, a needle head 6 is fixedly connected to one end of the needle body 2, and the shape of the needle head 6 is hemispherical. Such a setting can reduce the resistance of the needle head 6 entering the skin and is also helpful to control the direction. A chamfer is added at the intersection of the bottom of the needle head 6 and the needle body 2, in order to reduce the discomfort that may be caused when the needle head 6 enters the human body. A threading ring 7 is fixedly connected to the bottom of the needle head 6, and the shape of the threading ring 7 is a hollow semicircle. Such a setting is convenient for threading and fixing the protein line and facilitating the use of the device. A cutting edge 8 is fixedly connected to the bottom of the threading ring 7, and such a setting is helpful to break the opening, so that the needle head 6 can enter the skin. By setting the needle body 2 as a hollow setting, the cross-sectional area of the needle body 2 is larger than the cross-sectional area of the needle core 3.

This arc-shaped cutting edge 8 helps to break, so that the needle 6 enters the skin, so that it is easy to break when used, and can avoid injury. The needle core 3 and the connecting seat 1 are connected by a bellows 5, so that the needle core 3 can be controlled, effectively preventing the needle core 3 from falling off, reducing the phenomenon of the needle core 3 falling off during clinical treatment, avoiding pollution and waste of medical instruments, and the bellows 5 is in a straightened state when threading and folded when inserting the needle. The bottom of the needle 6 is fixedly connected with a threading ring 7, and the threading ring 7 is in a hollow semicircle shape. This arrangement is convenient for threading and fixing the protein line, and convenient for the use of the device. The bottom of the threading ring 7 is fixedly connected with a cutting edge 8, which is helpful for the opening to facilitate the needle 6 to enter the skin. The needle body 2 is hollow, and the cross-sectional area of the needle body 2 is larger than the cross-sectional area of the needle core 3. In this way, the needle core 3 can pass through the needle body 2, thereby pushing the protein line to the acupuncture point, and the needle handle 4 is provided with anti-slip patterns. This arrangement can cause hand slippage during operation, thereby affecting the buried thread effect.
