RESUMO
Lateral approach percutaneous spinal endoscopy， one of the most representative spinal endoscopic procedures， has ranked among the mainstream spinal operations that are facilitated to be understood and mastered by surgeons. The surgeries possess advantages of precise curative effect and wide scope of application after a series of conceptual innovations and reforms including YESS technology， TESSYS technology， eccentric trepan technology， visualized plasty technology， full-endoscopic visualization technology， and spinal endoscopy technology from the perspective of open surgery. Moreover， lateral approach percutaneous spinal endoscopy has formed a technology cluster that is inclusive with broad development prospects based on the introduction of high-tech technologies such as artificial intelligence and various navigation technologies.
