With the advantages of less operative injury and quicker postoperative recovery time, percutaneous endoscopic spine surgery system is currently one of the most widely used minimal invasive spine surgery techniques in China. However, this technique usually requires surgeon to operate in a single cannula, which brings much inconvenience such as limited vision, small range of motion and low efficiency. Meanwhile, the increasingly popular technique of unilateral biportal endoscopic (UBE) surgery possesses the advantages of better operation visual field, more flexible in operation, shorter learning curve period, handier surgical instruments for spine surgeon, and minimize radiation dosage caused by intraoperative fluoroscopy when comparing with single cannula endoscopic technique, since UBE requires an additional portal for surgical instruments while the anther portal is placed for arthroscope and pressure pump irrigation system. This technique has been applied to the treatment of degenerative diseases of cervical and lumbar spine, facet cyst, spinal epidural lipomatosis and abscess, and has achieved satisfactory clinical results.
经皮脊柱内镜凭借其手术副损伤小、术后恢复快等优势在我国迅速普及，然而该技术通常在单一通道下操作，存在手术视野受限、器械活动范围小、工作效率较低等不足。单侧双通道脊柱内镜手术中一个通道放置内镜并同时具备冲洗功能，另一个通道用于手术器械操作，与既往单一通道相比，具有手术视野范围更大、器械操作更灵活、学习曲线缩短、可使用术者熟悉的传统开放手术器械、术中透视次数更少等优势，目前已应用于颈椎、腰椎退行性疾病、腰椎关节突关节滑膜囊肿、硬膜外脂肪增多症以及硬膜外脓肿等脊柱疾病的治疗，并取得了满意的临床疗效。.
