Intervertebral foraminoscopy is accomplished through a minimally invasive spine surgery system consisting of a specially designed foraminoscope and corresponding complementary minimally invasive spine surgical instruments, imaging and image processing systems, and a bipolar radiofrequency machine. Patients undergoing laminectomy require only local anesthesia and do not need general anesthesia. The surgical incision in the low back is only about 0.5-1 cm and is accessed through the intervertebral foramen route. Intervertebral foraminoscopy uses bipolar radiofrequency electrodes to provide good intraoperative hemostasis, ablate the tissue adhering to the nerve, and create a clear view without touching the healthy tissue; it is possible to perform fibrous annulus formation, nerve destruction for discogenic pain, and remove osteophytes and treat spinal stenosis while completely removing the herniated or prolapsed nucleus pulposus, which is widely used in clinical practice. The operation takes about 1 hour, and the patient can get down and move around 2-3 days after the operation, and can be discharged 1 week after the operation.
