State of the Art and Development Trend of Laparoscopic Surgical Robot and Master Manipulator

BackgroundIn recent years, laparoscopic surgical robots have rapidly developed. However, most focus on the overall robotic systems, with few summaries on the laparoscopic surgical robots and the master manipulators.MethodsThis paper provides a summary and analysis of typical laparoscopic surgical robots, including the strengths and limitations of existing laparoscopic surgical robots. Additionally, the master manipulators are analysed and summarised from four aspects: structural design and optimization, time-varying delays, tremor suppression and force feedback. Further classification and summary are made based on the different methods used in each study.ResultsLaparoscopic surgical robots and the master manipulators still have some limitations. Therefore, the development trends of the laparoscopic surgical robots and the master manipulators are discussed from four aspects: structural materials, remote surgery, intelligence and human-machine interaction.ConclusionWith the continuous advancement of technology, laparoscopic surgical robots will play an increasingly important role in the field of surgery.
