Background

Various pains in the neck, shoulder, waist, back, joints, etc. have become the second highest incidence of respiratory tract infections in the world, and inflammation/adhesion of soft tissues (such as muscular fascia) and cartilage tissues are the main "primordial" of various pains. The local adhesion and even the nodule of the musculoskeletal fascia and other tissues can cause the tissue gap to be narrow or disappear, thereby limiting the blood circulation, clamping and pressing the nerves and even limiting the limb movement, and the symptoms of the musculoskeletal fascia and other tissues are integrated with pain, limited movement and nerve dysfunction, so that the physical and mental health and the life quality of a patient are seriously influenced.

The current treatment methods of the disease mainly comprise general treatment and minimally invasive surgery treatment, wherein the general treatment is divided into traditional Chinese medicine treatment, physical treatment and drug treatment, such as traditional massage, acupuncture, radio frequency physiotherapy and the like, and the minimally invasive surgery treatment is mainly a small needle knife treatment method which is a treatment of physical acupuncture separation by using a small needle knife similar to an acupuncture silver needle. In the treatment process, doctors repeatedly and multipoint pierce the myofascial pain part of the patient through the small needle knife, and the knife tip of the small needle knife is used for cutting tissues which are inflamed or adhered to achieve the purpose of separation, anesthesia is not applied in the treatment, and rehabilitation training is needed to be matched after the treatment.

For the above mentioned treatment methods, the general treatment methods are more, but the curative effect is poor, and most of the treatment methods are temporary treatment and temporary treatment, the illness state is easy to recur after stopping the treatment, and only the relieving effect can be achieved, so that the pathological problem of pain can not be fundamentally solved. While the rigid stripping operation of the small needle knife is still an invasive cutting operation, patients often have severe pain and even painful shock during the operation.

In addition, the rigid cutting of the small needle knife has great stimulation to surrounding tissues, bleeding and inflammatory edema are easy to cause, and if accurate rehabilitation training is not performed after operation, more serious adhesion can be caused again at a cutting interface.
