Application: Electrosurgical connection unit (Patent ID: US20240115311A1)

The patent filed by CMR Surgical Ltd. describes an electrosurgical connection unit for a surgical robot arm that connects an electrosurgical instrument to an electrosurgical generator. The unit includes an input port for receiving a driving electrosurgical signal and outputting activation signals, an output port for transmitting the driving signal to the instrument, activation switch units to control the signal waveform, a control unit for switch activation, and a measurement unit to monitor switch performance. The unit allows for the selection of different waveforms and ensures proper signal transmission between the generator and instrument.

The claims detail the specific components and functionalities of the electrosurgical connection unit, such as the configuration of input and output ports, the structure of activation switch units, the role of the control unit in waveform selection, and the inclusion of measurement and isolation devices for safety and performance monitoring. The patent also covers aspects like impedance measurement, capacitance emulation, and token generation for waveform control. Additionally, the patent extends to the integration of the unit into a surgical robot arm and a complete robotic system with an electrosurgical generator and instrument. Overall, the patent outlines a comprehensive system for precise and controlled electrosurgical procedures in robotic surgery.
