Remote Animal Experiments of "Tumai" Surgical Robot Based on 5G Technology

Abstract

Abstract Objective The remote robotic surgery based on 5G technology will be the future trend. To explore the feasibility, safety and stability of the domestic "Tumai" surgical robot in remote animal experiments under a 5G network environment.Methods The domestic "Tumai" surgical robot was used to perform remote cholecystectomy on experimental pigs in the animal operating room of Gansu Provincial Hospital from six different locations under a 5G network environment. The network rate, network delay, debugging time, loading time, operation time, blood loss, adverse events and intraoperative complications were recorded during the experiment. SPSS 25.0 statistical software was used, and the results were expressed as mean ± standard deviation.Results The experiment lasted 15 days, with a cumulative round-trip distance of > 3000 km, and the farthest surgical distance was about 780 km. Six remote animal cholecystectomies were completed. The average network delay was 55.16 ± 25.33ms; the average commissioning time was 65.17 ± 13.75 min; the average loading time was 5.12 ± 1.60 min; the average manipulation time of the robot was 22 ± 5.40 min; the average total operation time was 44 ± 4.23 min, the average blood loss was 5.83 ± 7.36 ml and one weak intraoperative network adverse. There was one intraoperative event and no intraoperative complications.Conclusions Using a domestic "Tumai" surgical robot system in the 5G wireless network environment could safely and stably perform remote animal surgery, which provides a theoretical foundation for the next step of remote clinical surgery.
