Beryllium needle is an apparatus designed and developed for the characteristics of dermal nerve entrapment syndrome caused by high tension state of soft tissue. Beryllium needle therapy is a treatment method that uses beryllium needle to cut subcutaneous tissues, fascia and muscles to reduce the pressure in the fascia cavity, lower the tension on the surface of fascia and loosen the adhesions, thus eliminating the stimulation and compression of sensory nerve endings and relieving pain. Modern beryllium needles are developed with titanium alloy material and are commonly used in the treatment of various orthopedic and traumatic diseases, peripheral nerve diseases, etc. They have the characteristics of good efficacy, small incision, little injury and no pain. Cervical cervical spondylosis: This disease is mostly seen in middle-aged and elderly patients over 40 years old, mostly caused by chronic strain injury or acute trauma. Because of the frequent daily activities of the cervical region, the high degree of activity and vulnerability to trauma, the neck is often prone to strain after middle age. External epicondylitis of the humerus, or tennis elbow. It is characterized by pain on the lateral side of the elbow joint and is mostly caused by acute and chronic inflammation at the lateral epicondyle of the humerus as a result of chronic strain. The epicondyle of the humerus is the starting point of the wrist extensor muscle of the forearm. Due to the frequent activities of the elbow and wrist joint and long-term strain, the starting point of the wrist extensor muscle is repeatedly strained and stimulated, causing partial tears and chronic inflammation or local changes such as synovial thickening and bursitis. Lumbar myofasciitis: due to excessive fatigue of the lumbar region, resulting in continuous stretching of muscles, fascia and ligaments, stagnation of qi and blood, and obstruction of meridians. Achillodynia is a condition caused by chronic injury to the metatarsal surface of the heel bone, mainly due to pain and difficulty walking. This disease occurs in middle-aged and old-aged patients, mostly due to the deficiency of liver and kidney or long-standing disease, the weakness of qi and blood, tendons and veins, coupled with obesity, weight gain, long walking and standing, resulting in excessive burden on the skin of the bottom of the foot, subcutaneous fat and metatarsal tendon membrane, which can cause chronic strain or osteophytes at the attachment of the heel nodes of the metatarsal tendon membrane, resulting in local aseptic inflammatory stimulation causing pain.
