Single-port robot-assisted endoscopic airway reconstruction using the newly developed Chinese EDGE SP robotic surgical sysem:A preclinical experiment in rabbits
Objective:To evaluate the safe and efficacy of the robot system EDGE SP in rabbit tracheal re-construction and explore the learning curve characteristics of the robot surgical system.Methods:A total of 27 rabbits were included in this study for tracheal reconstruction,which were divided into ro-bot surgery group,thoracoscopic surgery group,and open surgery group according to surgical meth-ods,with 9 cases in each group.We compared the anastomosis time and complications between each groups,and analyzed the learning curve of the robot surgery system.Results:The experiment of 27 rabbits was successfully completed,and there was no significant difference in the incidence rate of complications between the three groups(P＞0.05).The anastomosis time in the robotic surgery group was(18.49±3.87)min,which was significantly lower than that in the thoracoscopic group(vs.(23.02±1.66)min,P＜0.05),but was significantly higher than that in the open surgery group(vs.(6.95±0.25)min,P＜0.05).Compared with the thoracoscopy group,the robotic surgery group showed fewer tremors.As the number of cases in the robot experimental group increases,the time for tracheal anastomosis surgery in rabbits gradually stabilizes.Conclusion:Uniportal robot assisted tra-cheal anastomosis in rabbits is a safe,feasible,and effective surgical method that can significantly re-duce intraoperative tremor and operator fatigue.Our research also demonstrates the learning curve of robot assisted airway reconstruction.With the further accumulation of clinical experience with robots and the reduction of consumables costs,robot assisted surgery will play a greater role in minimally in-vasive thoracic surgery in the future.
