Neurosurgery is the discipline that treats diseases of the brain, spinal cord and peripheral nervous system with surgical methods as the main treatment. It is a high, sophisticated and advanced discipline in the current medical field and is recognized as the highest status field in medicine. The scope of neurosurgery treatment includes functional abnormalities of the brain and spinal cord, congenital developmental abnormalities of the brain and spinal cord, trauma to the brain and spinal cord, tumors, vascular lesions, including minimally invasive treatment of degenerative lesions of the spine and disc prolapse. Xu Jun, Department of Neurosurgery, General Hospital of Ningxia Medical University All neurosurgical tumors, blood vessels, disc removal and other surgeries are performed under a large operating microscope, and are operated by surgeons holding microscopic instruments under the mirror, for microsurgery, which is extremely delicate, complex, dangerous, minimally invasive, and takes a long time to operate. To do neurosurgery, the hands should not have a little tremor, so the surgery should be done in a chair with both arms suspended, one holding a suction device and the other holding a bipolar electrocoagulator or microscissors and other instruments. And a posture sitting, a sitting is a few hours or to insist on more than ten hours, eyes have been in the xenon lamp glare, a high degree of concentration, to see every blood vessel, nerve and surrounding details, careful operation, there can not be the slightest error. Surgeons are under a lot of pressure, especially neurosurgeons. Neurosurgery is the youngest and most complex discipline in medicine, the nervous system as the central system of human life, thought, action, once the disease, usually more serious performance, paralysis, dementia, often life-threatening. As the winner of the 2008 National Award for Science and Technology, the famous neurosurgeon Wang Zhongliang once described: “The human brain is like tofu, very soft, a pinch will break. Inside it concentrates 20% of the body’s blood, the nerve fibers are finer than hair strands, and the wiring is very complex.” Therefore, craniotomy is called “walking a tightrope on the abyss”, and every tiny movement requires perfection. Often a large craniotomy is done, the surgeon in charge will sit down in the chair.
