Description

thread embedding device

technical field

The invention relates to the field of medical devices, in particular to a thread embedding device.

Background technique

As an extension of TCM acupuncture and moxibustion, TCM catgut embedding is an external treatment method that embeds specific materials into certain acupoints, and achieves therapeutic effects through the two-way action of the catgut embedding material and acupoints. Under strict disinfection conditions, catgut embedding in traditional Chinese medicine uses embedding needles to embed sheep catgut or other absorbable protein threads in the selected position of the human body and indwell them. The continuous gentle stimulation of relevant acupoints over time can adjust the body's self-repair and metabolic balance to achieve the purpose of treating diseases. In TCM catgut embedding, the selection of acupoints and the amount of thread to be used can be determined according to the severity of the disease and the difference in deficiency and excess. It has the same effect as acupuncture in human activities, and achieves the purpose of dredging the meridians, regulating the yin and yang of the viscera, strengthening the body and expelling evil spirits.

Catgut embedding therapy in traditional Chinese medicine is the product of the combination of acupuncture theory and modern physical medicine. Acupoint closure, acupuncture and tissue damage and other stimulating effects. Through the stimulation of acupoint catgut embedding, the nerves and body fluids can play a series of regulatory functions, so as to promote the body's metabolism and improve immune function. Acupoint catgut embedding therapy has less trauma, less side effects, long intervals between treatments, and patients do not need to go to and from the hospital frequently; at the same time, it reduces the dosage and frequency of medication for patients, reduces side effects of drugs, is easy for patients to accept, and has good compliance. The field has a definite curative effect. Especially in the diseases of digestion, nerves, endocrine, and immune system, it has certain advantages. In addition, traditional Chinese medicine thread embedding is also widely used in sub-healthy people. exact effect.

In the process of extensive application of traditional Chinese medicine catgut embedding method, it is also found that there are many things to be improved. The total is as follows: (1) Suture embedding therapy is a medical method that invades the human body. The therapeutic effect is affected by the operator’s method of embedding. If the operator’s method and depth are not well grasped, the treatment effect will be affected. (2) Needle recipients are prone to needle fainting when they are hungry, weak, or fatigued, or have psychological fear of long needles; (3) The aseptic operation of thread embedding therapy is also worthy of attention. Currently, thread embedding is mostly used Injection needles are manually inserted with catgut before the operation, and the operation is completed on the spot by acupuncturists or health care personnel. It is necessary to place catgut multiple times. There are individual differences in the operation process, and it is difficult to completely control whether the whole process is sterile; (4) Chinese medicine Thread embedding is currently operated manually by operators and cannot be standardized.

In view of the needs and existing deficiencies of traditional Chinese medicine catgut embedding therapy, it is urgent to improve the traditional Chinese medicine catgut embedding treatment device, which can realize automation and standardization, ensure aseptic operation at the same time, and facilitate popularization and application.
