Minimally invasive intervertebral foraminoscopic spine technology is a new concept of minimally invasive spine surgery. It can perform herniated discs, foraminoplasty and fibular ring repair in all segments from the cervical spine to lumbar 5 sacral 1. The satisfactory outcome of the surgery can reach 85-90%. The surgical method is a minimally invasive spinal surgery system consisting of a specially designed foraminoscope and the corresponding supporting minimally invasive spinal surgical instruments, imaging and image processing system, and a dual-frequency radiofrequency machine. While completely removing the herniated or prolapsed nucleus pulposus, it removes osteophytes, treats spinal stenosis, and can repair the broken annulus fibrosus using radiofrequency technology. Because minimally invasive spine techniques are performed outside of the annulus fibrosus, the use of foraminotomy allows for precise surgery of the disc without touching healthy tissue. As a result, the integrity of the annulus fibrosus is maintained to the greatest extent possible and the stability of the spine is preserved, resulting in the least traumatic and most effective patient outcome of any procedure of its kind. The main advantages of the intervertebral foraminoscopy technique are as follows: 1. The surgery is performed while the patient is fully awake. The patient’s reaction can be detected at any time during the surgery. 2. The surgical site is reached through a very small percutaneous incision, minimizing the risk of infection during and after surgery. 3.Unlike traditional surgical techniques, the foraminal approach does not require partial removal of the intervertebral ligaments, conus or intervertebral joints. It also does not require cutting the trunk muscles, increasing postoperative stability and reducing trauma and pain. 4.Fast recovery after surgery, 1-3 patients can leave the hospital after surgery. Patients can return to work and ensure a high quality of life as soon as possible. 5.The unique design of cannula and surgical instruments can find and protect the nerve roots, protect the epidural and perineural venous system, prevent venous stasis and chronic neuroedema. This reduces the formation of perineural and epidural scarring. It will not damage the good dura and nerve ligament structure and reduce the occurrence of nerve root tethering. 6.The use of working cannula can reduce the injury of paravertebral muscles and loss of innervation. The stripping and stretching of the paravertebral muscles in open surgery often damage the paravertebral muscles and make the muscles lose innervation. In addition, postoperative segmental instability and slippage can be prevented. In accommodative disc herniation, intra-vertebral disc surgery decompression surgery protects the integrity of the posterior annulus fibrosus and posterior longitudinal ligament, thereby reducing the chance of recurrence of postoperative disc herniation. Indications for intervertebral foraminoscopy: Intervertebral foraminoscopy can be used for minimally invasive surgery of any herniated disc. All prolapsed and bulging disc material (including the 5th lumbar and 1st sacral intervertebral spaces) can be removed using the entire system under local anesthesia through the lateral foramina. The use of the whole system is indicated for any patient with nerve root symptoms or chronic pain caused by herniated discs or larger bony herniations that do not improve with conservative treatment.
