Abstract：Objective:To verify the safety of ureteral injury repair by constructing an experimental animal model of robotic telesurgery.Methods:The domestic endoscopic surgery robot MP1000 was used,and its master-slave sys-tems were placed in Beijing and Sanya,respectively.The distance between the two places which crossed the Qiong-zhou Strait,was about 3000 km.The animal model of complete amputation of lower ureter was established.Ureteral bladder replantation was performed.Key parameters including single operation time(minutes),single operation bleeding volume(ml),and network indicators were recorded.The bandwidth of network was then dynamically limit-ed in different intervals through technical means.,After completing the operation,the surgeon filled in a questionnaire to feedback the feeling of the operation.Results:All 8 robotic ureteral bladder replantation were completed success-fully.The operation time were 30-45 minutes,(37.5±4.5 min).The blood loss were 1-5 ml,(2.8±1.2 ml).The vi-tal signs of experimental animals were stable.During the operation,there was no mechanical failure.Under the nor-mal network environment,the data transmission was stable.After dynamic limitation of bandwidth,the operation vi-sual field is blurred,however the key visual information is intact,which can ensure the normal proceeding of surgery.But the surgeon needed to be more discreet on subtle maneuver.Conclusion:This study confirms that the animal model construction and robotic telesurgery for ureteral injury repair is safe and feasible,which provides a theoretical and practical basis for the follow-up human surgery.
