Intervertebral foraminoscopy Similar to a spinal endoscope, an intervertebral foraminoscope is a light-equipped tube that enters the intervertebral foramen from the side or side and back of the patient’s body (either in a flat or oblique fashion) and performs the procedure in a safe working triangle. The surgery is performed outside the disc’s fibrous annulus, and the herniated nucleus pulposus, nerve roots, dural sac and hyperplastic bone tissue can be clearly seen under direct endoscopic vision. The herniated tissue is then removed using various types of grasping forceps, the bone is removed microscopically, and the broken fibrous annulus is repaired with radiofrequency electrodes. The guardianship trauma is small: the skin incision is less than 7mm, just like the size of a soybean grain, bleeding is less than 20ml, and only 1 stitch after surgery. It is the minimally invasive treatment for herniated disc with the least trauma and the best effect on the patient among similar surgeries. Treatment Since the introduction of intervertebral foraminoscopy technology by domestic experts, pain specialists have performed foraminoscopic disc nucleus pulposus removal for many patients with lumbar disc herniation. Most of the patients can have their symptoms relieved as normal immediately after the operation and can be discharged from the hospital within three days. It is understood that this technique removes the herniated disc tissue under endoscopic surveillance through a special lateral foraminal approach, which is less invasive than the usual posterior approach. A typical laminectomy, in order to approach the target point, necessarily causes extensive damage to structures that play an important role in spinal stability, which usually requires immediate spinal fusion. In contrast, the laminectomy technique gradually enlarges the intervertebral foramen with a patented reamer and corresponding medical instrumentation, completely removing any herniated or prolapsed fragments as well as the degenerated inflamed nucleus pulposus. It also provides continuous irrigation and anti-inflammatory treatment of the lesion, uses radiofrequency electrodes to repair the fibrous annulus, ablates nerve sensitizing tissue, blocks the annular nerve branches, and relieves the patient of soft tissue pain.
