What are the advantages of minimally invasive surgery for lumbar disc herniation?

Minimally invasive means to achieve the best curative effect with minimal invasion or injury. In a narrow sense, it refers to the surgical technique with endoscope as the main means, and in a broad sense, it refers to minimizing all kinds of injuries to patients during the diagnosis and treatment as a whole, which runs through the whole clinical process. Minimally invasive surgery operating system perfectly combines advanced technology with clinic, and has highly clear observation performance, flexible and stable fixation devices and well-designed surgical instruments. It revolutionized the traditional surgical methods and promoted the development of spinal surgery technology. It is the safest and most effective technological innovation in invasive spinal surgery. It provides a safe and reliable treatment method for patients with little injury and short course of treatment. Compared with some traditional surgical methods, it has the following advantages: 1, less injury, less tissue peeling and less intraoperative bleeding. This operation only needs a skin incision of about 1.8cm, and the surgical channel is enlarged by expanding the tube, thus avoiding tissue damage and bleeding caused by peeling. Using bipolar electrocoagulation under the microscope, the bleeding site can be clearly found, the bleeding can be stopped, and the dural sac and nerve root can be operated more gently. 2. The damage to the stability of the spine is minimized. The surgical system only needs to remove the ligamentum flavum between laminae or bite off part of laminae and facet joints in a small range, so as to maintain the stability of the spine, shorten the postoperative bed rest time and recover quickly. 3. The operation is exquisite, which reduces the risk of surgical injury. Lighting adopts high-pressure xenon lamp cold light source (high brightness), and the field of view under the mirror can be enlarged to 64 times at most. Clear vision avoids some blind operations in traditional surgery, and expanded vision can better distinguish anatomical structures and reduce the risk of surgical injury. 4. Multi-site and multi-gap intervertebral disc surgery can be performed at the same time. For disc herniation with more than two gaps, operations with different gaps can be performed in turn, which not only eliminates the focus, but also reduces the damage to the spine and avoids the instability of the spine caused by total laminectomy or hemilaminectomy. 5. Because of the short operation time, less bleeding and less injury, the possibility of postoperative infection is minimized, the pain of patients is alleviated, the hospitalization time is greatly shortened, the dosage is reduced, and the hospitalization expenses are reduced.
