Description
Technical Field
The invention belongs to the technical field of medical equipment, and particularly relates to a bilateral multichannel fiber endoscope lumbar decompression operation device and a regulation and control method.
Background
The incidence of lumbar spinal stenosis increases with age, moderate stenosis incidence is 23.6% -77.9% and severe stenosis is 8.4% -30.4% in people over 40 years old. Patients with lumbar spinal stenosis often suffer from severe pain and weakness, affecting the quality of daily life and social productivity. Therefore, lumbar spinal stenosis is one of the main indications of lumbar surgery. In 2007, there were 37500 spinal stenosis surgeries in the united states alone, with a total cost approaching $16.5 billion.
In recent years, the lumbar disc excision and the vertebral canal decompression under the endoscope rapidly develop due to small tissue damage, short hospitalization time, few complications and rapid postoperative rehabilitation. The lumbar minimally invasive posterior decompression operation comprises microscopic assisted posterior decompression under a posterior small incision channel, laminoscope posterior decompression, unilateral double-channel (unilateral biportal endoscope, UBE) decompression and the like. Endoscopic laminectomy passes through the lamina and ligamentum flavum space, posteriorly to the disc. However, the operation requires pulling the dura mater sac, which may cause complications such as the rupture of the dura mater sac. In addition, the intervertebral approach requires general anesthesia or epidural anesthesia, and pure local anesthesia cannot meet the requirements of the operation. Endoscopic trans-foraminal discectomy can be performed under local anesthesia. However, the restriction of the transforaminal access field does not effectively address central sclerosis, and nerve roots may be irritated to create postoperative sensory impairment. The stenosis of the intervertebral foramen, the high iliac crest and the hypertrophic articular process can prevent the operation of the approach of the intervertebral foramen. Although the foramen mirror is gradually popularized in lumbar decompression operation, the current foramen mirror, foramen mirror and unilateral double-channel UBE still have the limitation that nerve roots can not be seen and the bleeding part in the vertebral canal can not be seen when the superior articular processes are resected or partially resected. Because the lumbar 5/sacral 1 intervertebral disc is shielded by the ilium wings, the difficulty of the operation of the foramen mirror and UBE is increased, and the risk of operation is increased. For patients with severe lumbar spinal stenosis, or slightly higher iliac wings, the foramen mirror and UBE cannot perform the decompression procedure.
Through the analysis, the problems and defects existing in the prior art are single visual angles, the relation between the upper articular process and the pressed nerve root cannot be clarified, the nerve root cannot be observed under direct vision, and the nerve root cannot be prevented from being damaged under the high-frequency vibration of a grinding drill and the cutting of rongeur when the upper articular process is cut.
