Microneedle therapy is a closed release procedure between surgical and non-surgical methods. It is formed by combining the needling method with the incisional surgical method. The operation of small needle knife therapy is characterized by stabbing deep into the treatment site to the lesion for easy cutting and peeling off the harmful tissues to achieve pain relief and dispel the disease. Its indications are mainly soft tissue injury lesions and bone and joint lesions. The advantage of small needle knife therapy is that the treatment process is easy to operate and is not restricted by any environment or conditions. The incision is small, no sutures are needed, the damage to human tissue is small, and it is not easy to cause infection, no adverse reaction, no obvious pain and fear for the patient, no need to rest after the operation, short treatment time, short course of treatment, easy for the patient to accept. Small acupuncture knife therapy is made of metal material in the shape of needle and knife like a kind of acupuncture tools. It is the product of the organic combination with soft tissue release surgery, and has a history of more than ten years. Therapy principle: small needle knife therapy is guided by the theory of Chinese medicine, absorbing the results of modern Western medicine and natural science, and then create a new discipline of medicine. It has the advantages of good efficacy, fast results, short treatment course, non-toxic side effects, wide range of applications, etc. It is a popular treatment method for patients. In December 2004, an appraisal meeting organized by the Ministry of Education concluded that small needle knife medicine has originality in physical therapy, technology and instruments, especially in clinical treatment, and has reached the international leading level, which was evaluated by the famous orthopedic expert, Professor Shang Tianyu. The famous orthopedic expert, Professor Shang Tianyu, commented that “Acupuncture medicine is a new discipline that combines Chinese and Western medicine in one furnace, with the strengths of Chinese medicine and the advantages of Western medicine.” In terms of theory, small needle knife medicine is guided by the theory of Chinese medicine, combined with modern science, drawing on the principles of surgery and innovation, formed the theory of closed surgery, a new theory of the etiology of chronic soft tissue injury, a new etiological theory of osteophytes, etc., which has important guidance for clinical treatment, and improve the efficacy of treatment. Because of the breakthrough in the basic research of etiology, small acupuncture medicine is widely used in internal, gynecological, pediatric and dermatological departments. Clinical application: 1, cervical spondylosis: acupuncture points: pain points are the main points.
