Unlike traditional posterior median lumbar spine surgery, the minimally invasive spinal foraminoscopy technique is performed through the lateral intervertebral foraminal safety triangle to remove the herniated or prolapsed nucleus pulposus and proliferating bone to relieve pressure on the nerve roots and eliminate the pain caused by nerve compression. The procedure is performed through a minimally invasive spinal surgery system consisting of a specially designed foramoscope and corresponding supporting minimally invasive spinal surgical instruments, imaging and image processing systems, and a dual-frequency radiofrequency machine, which perform various surgical operations in a very small canal space. This technique allows for the complete removal of the herniated or prolapsed nucleus pulposus while also removing osteophytes, treating spinal stenosis, and allowing for the repair of a broken annulus fibrosus using radiofrequency technology. With foraminotomy, the disc can be operated on precisely without damaging normal tissue. The minimally invasive intervertebral foraminotomy technique is the least invasive and most effective procedure of its kind, as it maximizes the integrity of the annulus fibrosus and maintains the stability of the spine. Minimally invasive foraminoscopic spine technology represents a new concept of minimally invasive surgery. The satisfactory outcome of the surgery can reach 95%. Because of its many advantages, the international field of spine surgery has recognized that laminectomy will become the leading surgical procedure in the field in the future. Minimally invasive laminectomy is a well-established and mature technique that has the following major advantages: 1. The surgery is done while the patient is completely awake. The patient’s reaction can be found at any time during the surgery. 2.The incision is small, about 7mm, with light postoperative pain and minimal scar. 3.No need to destroy the lumbar joints or cut the paraspinal muscles, which reduces the incidence of postoperative instability. 4.Fewer bone tissues are removed to reduce blood leakage and scar formation in the nerve root area. 5.The recovery after surgery is fast, and the patient can be on the ground one day after surgery. Patients can return to work and ensure a high quality of life as soon as possible. 6.The unique design of cannula and surgical instruments can protect the nerve roots, protect the epidural and perineural venous system, prevent venous stasis and chronic neuroedema. It can reduce the formation of perineural and epidural scar. 7.The surgical field of view is magnified 60 times, reducing the occurrence of dural and nerve root injury. 8.For inclusion type disc herniation, it can protect the integrity of posterior fibrous ring and posterior longitudinal ligament, thus reducing the chance of recurrence of disc herniation after surgery.
