It is important to ensure the redundancy of communication during remote surgery. The purpose of this study is to construct a communication system that does not affect the operation in the event of a communication failure during telesurgery. The hospitals were connected by two commercial lines, a main line and a backup line, with redundant encoder interfaces. The fiber optic network was constructed using both guaranteed and best-effort lines. The surgical robot used was from Riverfield Inc. During the observation, a random shutdown and restoration process of either line was conducted repeatedly. First, the effects of communication interruption were investigated. Next, we performed a surgical task using an artificial organ model. Finally, 12 experienced surgeons performed operations on actual pigs. Most of the surgeons did not feel the effects of the line interruption and restoration on still and moving images, in artificial organ tasks, and in pig surgery. During all 16 surgeries, a total of 175-line switches were performed, and 15 abnormalities were detected by the surgeons. However, there were no abnormalities that coincided with the line switching. It was possible to construct a system in which communication interruptions would not affect the surgery.
确保远程手术过程中的通信冗余非常重要。本研究旨在构建一种通信系统，即在远程手术过程中发生通信故障时，不会对手术造成影响。通过两条商业线路（主线路和备份线路）和冗余编码器接口将医院连接起来。使用保证线路和尽力而为线路构建光纤网络。所使用的手术机器人来自 Riverfield Inc.。在观察过程中，反复进行了随机的线路关闭和恢复过程。首先，研究了通信中断的影响。接下来，我们使用人工器官模型进行了手术任务。最后，12 名经验丰富的外科医生对实际猪进行了手术。大多数外科医生在静态和动态图像、人工器官任务以及猪手术中都没有感觉到线路中断和恢复的影响。在所有 16 次手术中，共进行了 175 次线路切换，外科医生检测到 15 次异常。但是，没有与线路切换同时发生的异常。因此，可以构建一种通信中断不会影响手术的系统。
