Description

Needle inserting device for thread burial needle

Technical Field

The utility model relates to a thread burial needle, in particular to a thread burial needle inserting device which can insert a needle quickly and control the needle inserting depth accurately.

Background

The catgut suture is the development of the acupuncture technology of the traditional Chinese medicine, combines the modern medical technology with the traditional meridian theory, and embeds the catgut suture or the biological protein suture in the acupuncture points to stimulate the acupuncture points, regulate the meridians and treat diseases for a long time. The good feeling is the basis of effect, the catgut is buried in the acupuncture point of the human body by the acupuncture point buried line, the feeling of good feeling after acupuncture can be more lasting and can reach more than 10 days, therefore, the curative effect can be stabilized, the problems of limited action time and multiple times of common acupuncture and moxibustion are effectively solved, the problems of psychological burden, economic burden and long treatment period of a patient caused by repeated clinics are solved, the catgut is more suitable for the characteristic of rapid playing of modern life, convenience is brought to the patient, and the catgut is widely applied to various diseases in clinic, such as: cervical spondylosis, prolapse of lumbar intervertebral disc, postherpetic neuralgia, sciatica, muscle spasm, neurasthenia, epilepsy, cyclomastopathy, dysmenorrhea, amenorrhea, pelvic inflammatory disease, acne, asthma, gastritis, and simple obesity. When the thread is buried, the faster the needle insertion, the less pain the patient feels, the easier the patient can accept the thread-burying therapy, the treatment effect is improved, the treatment course is shortened, and the burden of the patient is reduced. Conversely, the slower the needle insertion, the more severe the pain felt by the patient. However, in clinic, many doctors often cannot perform quick needle insertion to relieve pain of patients during needle insertion, so that the popularization of the catgut embedding therapy is limited. Even though the doctor can insert the needle quickly, the doctor is difficult to control the depth of the needle insertion, which causes a series of problems, such as shallow muscle, which may hurt the internal organs and tissues if the needle is too deep (if the doctor can find and deal with the needle in time to save the patient, for example, when the patient is buried in the bladder meridian point on the back of the patient, if pneumothorax is caused, the patient will have difficulty in breathing immediately, the doctor can find and deal with the needle in time, if the doctor cannot find the needle in time, the doctor can leave hidden troubles, for example, when spleen or liver of the patient is injured, the internal organs of the patient will be chronically bled, the patient will not have obvious abnormal symptoms at that time, the doctor cannot find the needle in time easily, the patient can be saved, the patient can die, unnecessary injuries (even if the needle is withdrawn outwards, the injuries are caused), or even medical accidents are caused, initiating medical disputes; if the needle is too shallow, the absorption of the catgut may be affected, which may not only fail to achieve the therapeutic effect, but also may cause problems of liquefaction of fat, induration and the like, even the catgut may be escaped out of the human body from the needle inlet along with the movement of the patient, i.e. a part is in the human body and a part is out of the human body, and infection is easily caused, which may cause medical accidents and cause medical disputes. When the needle is inserted too deeply by mistake, there is a high possibility that the patient gets sick of the needle, urgent handling by the doctor is required, the work load of the doctor is increased, and more serious problems such as shock are caused if the handling is not performed properly. When the needle is inserted too shallow by mistake, the doctor needs to continue to insert the needle into the human body for even more times, so that the pain of the patient during the needle insertion is aggravated (the pain is aggravated once every time the needle is inserted), and the working efficiency of the doctor is influenced. Under the condition of the prior art, the speed of needle insertion and the depth of the needle insertion are completely influenced by human factors. If the patient cares carelessly, the pain of the patient during the needle insertion can be aggravated, even medical accidents can be caused, medical disputes can be caused, and the popularization of the catgut embedding therapy can be limited. How to insert the needle rapidly in clinic and at the same time, how to control the depth of the needle insertion to reduce the pain of the patient during the needle insertion and ensure the safety of the operation become the concern of the technicians in this field.
