Modeling and Analysis of a Telesurgery Environment Using Stochastic Petri Nets

摘要

Over the past few years, surgeries performed by robots have increased considerably. For telesurgery (or remote surgery) to be performed satisfactorily, synchrony between the robot and the communication links is essential. However, no studies analytically evaluate these remote surgery environments or calculate the probability of delivering messages when such surgeries are performed between two hospitals. The main objective of this work is to model a telesurgery environment, allowing metrics such as availability and reliability to be obtained, as well as the probability of a message being delivered in a given period. The results showed that the best scenario is to use redundant links for robot communication, such as 4G and WiFi, and that redundant links guarantee a greater probability of message delivery during telesurgery. Additionally, the results can help the maintenance team (or medical team) to better plan the infrastructure used in telesurgery, and, consequently, avoid failures that could endanger the lives of patients.
