20200289218 | NEAR FIELD COMMUNICATION BETWEEN A SURGICAL INSTRUMENT AND A ROBOTIC SURGICAL SYSTEM - Various exemplary methods, systems, and devices for near field communication (NFC) between a surgical instrument and a robotic surgical system are provided. In general, a surgical tool is configured to move between different modes of communication with a robotic surgical system to which the tool is releasably and replaceably coupled. The different modes of communication are detectable by the robotic surgical system by the tool's frequency of NFC with the robotic surgical system. The tool includes a mechanism configured to be manipulated by a user of the tool to move the tool between the different modes of communication. The tool operating in a first mode of communication indicates to the robotic surgical system that the tool is operating in a normal state. The tool operating in each of one or more additional modes of communication indicates that the tool is operating in an error state. | 2020-09-17 |
