With the extensive application of surgical robots represented by Da Vinci in minimally invasive surgical procedures,robotic technology has gradually extended to the field of flexible endoscopic surgery like digestive endoscopy.Many studies have shown that surgical robots can also improve the operational efficiency and safety of flexible endoscopic surgery and optimize the learning curve.However,due to the narrow and tortuous lumen of digestive tract,the development and design of flexible digestive endoscopic surgical robot is relatively more difficult.In this paper,the research and development characteristics of the flexible digestive endoscopic surgical robot are introduced from the aspects of carrier length,flexibility and ergonomics,and its future clinical application is prospected,with a view to facilitating the application of the flexible surgical robot in the minimally invasive surgical procedures of natural passages such as digestive,respiratory and urinary tract.
