Similar to a spinal endoscope, an intervertebral foramoscope 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 surgical trauma is small: the skin incision is only 7mm, like the size of a soybean grain, bleeding is less than 20ml, and only 1 stitch is needed after the operation. It is the least traumatic and most effective minimally invasive treatment for disc herniation among similar surgeries. The selection criteria for intervertebral foraminoscopic or endoscopic microdiscectomy are not fundamentally different from those for laminectomy and disc removal. Patients with herniated discs selected for minimally invasive surgery must exhibit signs and symptoms of nerve root compression and must meet the following conditions: 1. persistent or recurrent radicular pain; 2. more radicular pain than lumbar pain. If the symptoms of lumbar pain are greater than leg pain in patients with moderate or less bulging can first do cryogenic plasma meduloplasty; 3, after strict conservative treatment has failed. Including the use of steroidal or non-steroidal anti-inflammatory painkillers, physical therapy, homework or condition training procedures, conservative treatment is recommended for at least 4-6 weeks, but if there is a progressive increase in neurological symptoms, immediate surgery is required; 4, no history of drug abuse and psychological disorders; 5, positive straight leg raise test, bending difficulties; the technique is operated under visualization, the field of vision is clearer, the risk of misoperation can be effectively avoided, postoperative bed rest 1 The technique is operated under visualization, with clearer vision and can effectively avoid the risk of misoperation. It brings new hope for the majority of patients with lumbar disc herniation!
