This method was invented by Director Gao Yi in 1999 and has cured more than 2800 cases of lumbar disc herniation. The method uses puncture expansion technology to form a 2.0 mm artificial channel between the skin and the lumbar spinal canal, then the head of the minimally invasive relaxer guide is inserted into the lumbar spinal canal, and the adherent nerves in the spinal canal are loosened under monitor surveillance, and the loosened nerves are moderately displaced to avoid the herniated disc. The method has the following advantages: 1. High efficacy: the cure rate is over 98%. 2, no incision: the incision is only 2 mm, without removing the nucleus pulposus, preserving the normal physiological function of the intervertebral disc. 3.Less pain: the treatment process is only slightly painful. 4.Fast effect: the pain disappears immediately after relaxation, and all patients walk back to the ward from the operating room by themselves. 5. Absolute safety: the head of the relaxer is made of special soft material, and absolutely no blood vessels and nerves will be damaged during the operation. 6.Fast recovery: functional exercise starts on the third day after surgery, and complete recovery in about 7 days. 7, wide range of application: more than 95% of patients with lumbar disc herniation are suitable for this method of treatment
