Background

Acupuncture and moxibustion is one of the commonly used manipulations in ancient China for treating various diseases, wherein the acupuncture therapy is to insert an acupuncture needle into a patient according to a certain acupuncture point and treat the diseases by twisting, lifting and other manipulations. However, the acupuncture needle used in the conventional acupuncture therapy cannot be used for simultaneously injecting liquid medicine to enhance the clinical curative effect, and if the medicine needs to be injected, the patient needs to be pricked again by using the injector, so that the patient is injured for the second time, and the acupuncture needle is not acceptable by the patient. And has the defect that adverse effects and even medical accidents can not be found and treated in time due to the fact that blood vessels are punctured in the process of needle treatment, particularly large blood vessels.

The small needle knife therapy is a closed loosening operation between a surgical method and a non-surgical method, and is formed by combining a needle punching method on the basis of an open surgical method. The operation of the small needle knife therapy is characterized in that the deep part of the operation part is punctured to the pathological change part for easy cutting, peeling and other stimulation with different strengths so as to achieve the purposes of relieving pain and removing diseases. In the treatment process of the traditional small needle knife, on one hand, the liquid medicine cannot be injected at the same time to enhance the clinical curative effect, and if the medicine needs to be injected, the patient needs to be pricked again by using the injector, so that the patient is damaged for the second time, and the small needle knife is not acceptable by the patient; on the other hand, when the diameter of the small needle knife is 0.5-1.2 mm, the small needle knife can only cut easily at a pathological change part to strip harmful tissues, but can not perform needle operation, needle retention and needle lifting and insertion at acupuncture points to play an acupuncture point stimulation effect, so that great pain is brought to a patient to make the patient unacceptable, and the clinical curative effect is limited; moreover, the defect that the puncture of blood vessels, especially large blood vessels, cannot be timely found and treated in the course of acupuncture treatment, which may cause adverse effects and even medical accidents, exists.
