Research Progress of Unilateral Biportal Endoscopic Spinal Surgery in Lumbar Spine

: Percutaneous spinal endoscopy is rapidly popularized in China because of its advantages of small surgical side injury and fast postoperative recovery. However, this technology is usually operated in a single channel, which has the disadvantages of limited surgical field of vision, small range of instrument activities and low work efficiency. In unilateral double channel spinal endoscopic surgery, one channel is equipped with endoscope and flushing function at the same time, and the other channel is used for the operation of surgical instruments. Compared with the previous single channel, it has the advantages of larger surgical field of vision, more flexible instrument operation, shorter learning curve, the use of traditional open surgical instruments familiar to the operator, and fewer intraoperative fluoroscopy times. This paper analyzes the current situation and clinical value of its clinical application in lumbar diseases.
