Description

Bullet-shaped thread burying device, acupoint thread burying method and acupoint thread burying gun

Technical Field

The invention belongs to the technical field of medical instruments, and particularly relates to a bullet-shaped catgut embedding device, an acupoint catgut embedding method and an acupoint catgut embedding gun.

Background

The catgut implantation at the acupuncture point combines traditional Chinese medicine and western medicine on the basis of the traditional acupuncture manipulation, and generates lasting and soft biological, physical and chemical stimulation to the acupuncture point through an absorbable catgut (such as catgut suture), so that stimulation information and energy are transmitted into the body through the channels and collaterals, and the purposes of dispelling the blood and qi and regulating the blood and qi are achieved. The acupoint catgut embedding method belongs to a compound acupuncture therapy, integrates various effects of acupuncture, needle retention, needle embedding and the like, and after conventional acupuncture, an absorbable line body is retained in an acupoint, so that the prevention and treatment effect is enhanced, the stimulation time is prolonged, the treatment frequency is reduced, the medical cost of a patient is reduced, and the method has the advantages of economy, high patient compliance and the like. At present, the acupoint catgut embedding therapy is widely applied to the treatment of various diseases such as obesity, facial paralysis and the like, wherein digestive system diseases such as stomachache, abdominal pain, abdominal distension, constipation and the like are dominant diseases for the treatment.

Modern medicine believes that the acupoint catgut embedding method has the following functions: restoring nerve function and regulating nerve reflex. The catgut embedding therapy plays a role in correcting disorder and rehabilitating the nervous system through continuous benign stimulation and neurotransmitter influence generated after implantation. Most of nerve and circulatory diseases have long recovery period, and are mostly required to be controlled by taking medicines for a long time, and stimulation generated by catgut embedding at acupuncture points induces sustainable conduction of nerve information and regulates transmitter secretion, so that the nerve and circulatory diseases can be used together with medicines to reduce medicine intake, which cannot be replaced by common therapies. (II) enhancing the immunity of the human body and improving the local circulation. The catgut embedding therapy can enhance the immunologic function by regulating and controlling the cell metabolism, improve the circulation of the damaged part and accelerate the recovery of diseases. The catgut embedding method can promote the growth of the vascular bed around the acupoint, thereby regulating blood volume and improving the circulation around the acupoint, and related clinical researches prove that the catgut embedding method has definite curative effect on diseases of respiratory and digestive systems and can partially replace the use of medicaments. And thirdly, cell factors are regulated, and the metabolism of the organism is improved. The catgut embedding therapy can generate the effects of resisting inflammation and repairing gastrointestinal mucosa by regulating related inflammatory factors, and simultaneously, the physiological and chemical effects generated by catgut embedding dissolution can soften subcutaneous tissues and muscles, and the continuous infiltration effect can stimulate surrounding muscles and ligaments, promote muscle strengthening and recovery and improve the metabolism of the organism.

The thread burial needle commonly used in clinic at present mainly comprises a needle handle, a needle core, a needle body and a spring. The needle handle is firmly connected with the needle body, and the needle core passes through the stainless steel needle body through the needle handle. When the thread embedding needle with the thread body is inserted into an acupoint, the needle core is pushed to push the thread body into the acupoint. However, the practical operation of the needle tool still has the following problems:

firstly, an operator needs to cut the absorbable thread into short threads in advance, the short threads need to be manually threaded into the needle core once before each acupuncture point operation, in addition, more acupuncture points are generally taken clinically, each acupuncture point needs to be threaded again, the operation is complex, time and labor are consumed, meanwhile, the pollution risks of the needle head and the absorbable thread are increased, and the real sterile operation cannot be achieved.

Secondly, need place the line body in the hollow needle, the needle body is thicker, and operating speed will lead to the syringe needle to pierce the skin process pain and feel stronger slowly, and it is long to prick the process duration at every turn, and patient experience feels and compliance is relatively poor, requires relatively to operator's technical merit simultaneously, has restricted the clinical popularization of acupuncture point sunkening cord to a certain extent.

The depth of skin is penetrated to present thread burial needle mainly relies on the subjective judgement control of operator's individual, can't adjust the depth of inserting the needle according to patient's fat thin, the abundant degree ration of different position muscles, not only can take place to bury the line too shallowly and lead to the line body to spill over, and some acupuncture point acupuncture is too deeply moreover can lead to adverse reaction, increases the operation risk.

And because sterile operation is not needed, a new thread burying needle is replaced after each acupoint operation is finished, the convenience and the economy of thread burying are greatly reduced, and serious adverse effects are caused because an operator does not pay attention to sterile operation, the disinfection is not strict, and the needle head is repeatedly used for many times to cause infection.
