Intervertebral foraminoscopy technology makes the application of minimally invasive technology more scientific, safer and more secure, which is conducive to the scientific and healthy development of the mainstream minimally invasive spinal technology, and at the same time, due to the fact that the technology is easy to learn and easy to master, it has become a mature and worthwhile mainstream technology to be promoted. Intervertebral foramenoscopy is the most advanced minimally invasive treatment technology for herniated disc. The whole operation is done under local anesthesia through tiny skin incision, and the patient is awake throughout the whole procedure, which reduces the chance of nerve root damage. This technology not only has the advantages of small trauma, less bleeding, light injury and fast recovery, but also visualization of surgical operation, high safety and fast recovery. Orthopedic experts at home and abroad unanimously agree that, for the time being, no matter from the point of view of therapeutic efficacy or the degree of damage to normal tissues, Intervertebral Foraminoscopic Nucleus Pulposus Removal is the most reliable method for treating herniated disc, and it is the most advanced minimally invasive spinal surgery in the international arena. Intervertebral Foraminoscopic Surgical System Like all endoscopic techniques, intervertebral foraminoscopic technique has the advantages of small wounds, good field of vision and illumination, short hospitalization time, and quick recovery. Intervertebral foramenoscopy technology is to make a small incision of about 0.6cm in the skin, through a sleeve, under the magnified monitoring of the endoscope, to see the anatomical structure more clearly, to remove the protruding disc tissue and deal with the stenosis of the spinal canal with surgical instruments, and to directly relieve the nerve compression. The surgical principle, operation process and clinical efficacy are the same as those of open surgery. Currently, intervertebral foraminoscopy technology has highly clear observation performance, flexible and stable fixation device and well-designed surgical instruments, which facilitates orthopaedic surgeons to carry out treatment smoothly and efficiently. Intervertebral foraminoscopy technology is fundamentally different from the previous percutaneous discoscopy, which is an organic combination of traditional open disc removal technology and endoscopic technology, and is a minimally invasive and endoscopic version of the traditional lumbar disc surgery, which can clearly display the surgical field on the monitor, with special surgical instruments, small incision, small range of peeled tissues, less bleeding, and less damage to normal tissues, and can directly visualize the dural sac and nerve root compression, and can directly visualize the dural sac and nerve root compression, and can directly visualize the dural sac and nerve root compression, and can directly visualize the dural sac and nerve root compression, and can directly visualize the dural sac and nerve root compression. It can visualize the dural sac and nerve root under direct vision and operate under direct vision, the nerve root decompression is thorough, it can get satisfactory and reliable therapeutic effect and at the same time reduce the occurrence of neurovascular injury and other complications, the use of this endoscopy can complete the lumbar disc nucleus pulposus removal and nerve root channel cleaning and other surgeries, so it is suitable for most types of lumbar disc herniation.
