Foraminoscopy is a very minimally invasive procedure and is usually done through local anesthesia or less than half anesthesia. The patient needs to lie on his or her stomach or side on the operating table, and the patient’s back is sterilized with complex iodine, and then an anesthetic is injected into the surgical site, which may also be painful and distended. However, once the anesthetic is in place, the patient has no particular pain. After the anesthetic has taken effect, a fine guide needle is used to accurately define the required puncture route with the aid of fluoroscopy. After the route has been determined, a working channel is established using various instruments. After the working channel has been established in the desired target position, the intervertebral foramenoscope option system is implanted, and the entire procedure is performed under a television set. If the patient is bold enough, the patient can watch the entire procedure on his or her own and can clearly see the herniated discs and nerves. After these structures are clearly separated, various types of small forceps will be used to remove the protruding disc nucleus pulposus tissue through the working channel, remove the hyperplasia, and then repair the broken annulus fibrosus with radiofrequency and electrodes, so that the nerve is no longer under pressure. The whole process can be clearly felt by the patient with the surgery before a significant change. Pain symptoms can be significantly relieved as the surgery progresses, and the leg will become significantly easier. If it goes well, the entire procedure can be completed in about 30-40 minutes.
