The knife treatment is equivalent to a minimally invasive surgical treatment. If done properly and applied to the appropriate conditions, it is largely harmless. The knife is a long-handled needle with a small tip that is used to treat chronic soft tissue injuries and soft tissue adhesion disorders. It cuts away the tissues where chronic injuries occur, relieves tissue adhesions, promotes the regeneration of blood vessels at the place of injury, creates new blood circulation, improves the local blood supply of the injury, and accelerates tissue repair. If the symptoms are caused by the adhesion of fascia, muscle membrane and ligament, the needle knife can quickly cut off the adhesion, the effect is relatively fast, and the needle knife is similar to acupuncture treatment, it can stimulate the acupuncture points to stimulate the local soft tissues, activate the activation of the tissues, and promote the absorption of inflammatory substances, so as to achieve the therapeutic purpose. Needle knife treatment can not be applied to patients with fever symptoms or internal diseases, skin and local infections, muscle necrosis, severe hypertension, heart disease and other underlying diseases, and can not avoid the important blood vessels and nerves can not be applied.
