Based on 12 years of experience in minimally invasive surgery, Hajikata, a Japanese, first reported the use of percutaneous disc rotational resection for lumbar disc herniation in 1975. The principle is that by reducing the volume of the nucleus pulposus, the inclusion of the nucleus pulposus by the annulus fibrosus disappears and the pressure in the disc is reduced, thus reducing the irritation to the nerve roots. The procedure is to use a fine guide needle to puncture into the diseased intervertebral disc under X-ray fluoroscopy, and to reciprocate, rotate, move and cut the nucleus pulposus tissue with the annular drill of the suction device, so as to reduce the pressure inside the disc and achieve symptom relief and cure. The indications are cervical spine: nerve root type and spinal cord type cervical spondylosis; lumbar spine: lumbar disc herniation with intact fibrous ring.
