Lumbar disc herniation is a common and frequent disease in spinal surgery. About 53% of light manual laborers and 64% of heavy manual laborers experience low back pain, and about 35% of those with low back pain develop lumbar disc herniation. Nucleus pulposus removal is still the most effective surgical method to treat lumbar disc herniation. Yang Cao, Orthopaedic Department of Wuhan Union Medical College Hospital Minimally invasive technology is the development trend of surgery, intervertebral foramenoscopy technology with endoscopy through the intervertebral foramen into the spinal canal to carry out nerve root release and decompression TESSYS (transforaminal endoscopic spine system) technology, based on traditional nucleus pulposus removal surgery, perfect combination of percutaneous puncture technology for micro-injury and spinal endoscopic technology, in a minimally invasive operation, in a minimally invasive operation of lumbar disc herniation. Based on the traditional nucleus pulposus removal technique, it perfectly combines the minimally invasive percutaneous puncture technique and the endoscopic spine technique to maintain the normal anatomical structure of the spine to the maximum extent under the premise of minimally invasive operation. Advantages of intervertebral foramenoscopy: Minimally invasive: applying percutaneous puncture technique, the soft tissues are expanded step by step after puncture without cutting muscles and ligaments or removing the vertebral plate and ligamentum flavum, which has no obvious effect on stability. The skin incision is only 8 mm. High safety: less bleeding, high-definition endoscopic camera system makes the surgical field of view clearer, greatly reducing the risk of misuse. Wide range of application: It is suitable for almost all types of lumbar disc herniation, including giant type, prolapse type and revision of disc herniation. Fast recovery: immediate pain relief, almost no pain reaction to the surgical incision after surgery, no need to place drainage at the incision site. After the operation, you can go down to the ground, take care of your own bowel movement, simple nursing care, and you can be discharged from the hospital in an average of 3 to 5 days for postoperative hospitalization and observation.
