Minimally invasive therapy for lumbar disc herniation – foraminoscopic nucleus pulposus excision In recent years, lumbar disc herniation has occurred frequently, bringing great distress to the life and work of patients. Many patients give active conservative treatment such as traditional acupuncture, massage, traction and medication, but the effect is not good, recurrent lumbar pain, the main reason is that many patients do not have a thorough understanding of lumbar disc herniation and do not choose an effective treatment method. Lumbar disc herniation: a syndrome caused by degeneration of the intervertebral disc, rupture of the annulus fibrosus, protrusion of the nucleus pulposus stimulating or compressing the nerve root, cauda equina, is one of the most common causes of low back pain, the following figure: Figure 1: normal disc and lumbar disc herniation Figure 2: evolution of lumbar disc herniation from mild to severe Lumbar disc herniation traditional surgery is the more common treatment of lumbar disc herniation Surgery can eliminate the protrusions compressing the spinal nerve and other surrounding tissues more thoroughly, and fundamentally relieve the clinical symptoms of the lumbar legs. Although traditional decompression can bring immediate results and reduce the symptoms of herniated discs such as low back pain, nerve compression and walking disorders relatively quickly, traditional open surgery can damage the normal spinal tissue structure and aggravate the injury when the nerve is opened during decompression, and scar adhesions can form around the dural sac and nerve roots after surgery, bringing new risks to patients. Minimally invasive refers to a surgical concept that achieves the best surgical outcome with minimal invasion and physiological disturbance, and is characterized by minimal trauma to the body compared to conventional surgery. The concept of minimally invasive spine has existed for 50 years, from the earliest minimally invasive treatment of papain to “dissolve” herniated discs, which caused more nerve damage, to the continued development of technology and medical technology, with “access, light, direct vision, and visibility The minimally invasive technology of “access, light, direct vision, and visibility” has developed rapidly, and more and more patients with lumbar disc herniation who need surgical treatment have been effectively solved by such “minimally invasive” methods, especially for teenagers and elderly people. Minimally invasive surgical treatment of lumbar disc herniation is the use of television microscopic discoscopy and intervertebral foraminoscopy equipment to enter the lesion (herniated) site through a small tube (working channel), and remove the herniated disc under “direct vision” with the help of television microscopic endoscope and tiny instrumentation tools to release the compression of the lesion on the nerve and achieve the purpose of treating The purpose of this procedure is to treat low back pain. This procedure not only has good therapeutic effect, but also protects the paraspinal muscles and soft tissues from surgical effects and damage, and protects the structural integrity and stability of the bony tissues of the spine. Compared with traditional surgery, it has many advantages as follows: 1. Small incision: tiny incision, 5-8 mm, basically no scar; 2. Small trauma: percutaneous puncture entry, no stripping of deep tissues, no destruction of bony structures and spinal stability; 3. Less bleeding: small surgical incision, small trauma, no stripping of internal tissues, electromagnetic coagulation device cocoa can be matched, almost no bleeding during surgery; 4. Due to the small surgical injury and bleeding, the negative reaction to the surgery is significantly reduced; 5. Fast recovery: the surgery has little impact and damage to the normal tissue structure, and the patient can move around on the ground 3-4 hours after surgery and be discharged from the hospital in 2-3 days; it greatly reduces the damage to the organs and the interference with the function of the organs, so that the recovery time after surgery is shortened; 6.
