Minimally invasive refers to the best results with minimal invasion or damage. In a narrow sense, it refers to surgical techniques that use endoscopy as the main tool, while in a broader sense, it refers to minimizing all kinds of damage to patients during the treatment process as a whole, and is used throughout the clinical process. Minimally invasive surgical operating system combines advanced technology and clinical perfection, with highly clear observation performance, flexible and stable fixation device and well-designed surgical instruments. It revolutionizes the traditional surgical approach and promotes the development of spinal surgery technology, which is the safest and most effective technological innovation for invasive spinal surgery. It provides patients with a safe and reliable treatment method with little damage and a short course of treatment. Compared with some traditional surgical methods have the following advantages: 1, small injury, less tissue stripping, less intraoperative bleeding. The operation only requires a skin incision of about 1.8 cm, and the surgical channel is enlarged through the expansion tube to avoid tissue damage and bleeding due to stripping. The use of bipolar electrocoagulation under the microscope can clearly find the bleeding site and stop the bleeding, and the dural sac and nerve roots can be operated more gently. 2. The degree of damage to the stability of the spine is reduced. The operating system only needs to remove the intervertebral ligament or bite off part of the vertebral plate and small joint protrusion in a very small extent, so the stability of the spine is maintained, and the postoperative bed time is shortened and recovery is fast. 3, the operation is fine, reducing the risk of operational injury. Using high-pressure xenon lamp cold light source illumination (high brightness), the maximum area of the field of view under the mirror can be put to 64 times. The clear field of view avoids certain blind operations of traditional surgery, and the enlarged field of view can better distinguish anatomical structures, reducing the risk of operational injury. 4. Simultaneous multi-site and multi-gap disc surgery. For herniated discs with more than two interspaces, the surgery of different interspaces can be performed sequentially, which not only removes the lesions but also reduces the spinal destruction and avoids the spinal instability brought about by full-plate or half-plate surgery. 5. With short operation time, less bleeding, less injury, the possibility of postoperative infection is reduced to the minimum, the patient’s pain is reduced, the hospital stay is greatly shortened, the amount of medication is reduced, and the hospitalization cost is lowered.
