回顾机器人手术系统的组成和发展史。在结直肠癌根治术中，机器人手术系统已得到广泛应用，手术操作时间明显缩短，手术安全。机器人手术系统具有三维图像稳定性和清晰性、手术操作便利性等优势。触觉反馈缺失、手术时间延长等是其不足。

Abstract    The construction of robotic surgery system and the brief history of robotic surgery were reviewed. Robotic surgery had been applied widely in radical colorectal surgery. The operation was safe and operation time was shortened obviously. The outstanding advantages of robotic surgery included the stable and brilliant three-dimension image, the convenience of surgery manipulation. The disadvantages like the lack of force feedback and the prolonged surgery time were also evaluated.
