Abstract
The invention relates to a modular electrosurgical system for using electromagnetic (EM) radiation, such as radio frequency (RF) or microwave EM radiation, to treat biological tissue. In one example, control of the modules is centralised in a remote computing device which can communicate wirelessly with the modules of the system. In one example, different optional modules may be combined together with core modules to provide the system with different electrosurgical capabilities.
Claims24
A modular electrosurgical system comprising:
- a remote computing device having at least one processor and at least one memory including computer program code;
- a controller module having a wireless communication interface operable to wirelessly communicate with the remote computing device so as to receive data therefrom, the controller module being operable to provide control commands based on the received data;
- a signal generator module in communication with the controller module so as to receive the control commands, the signal generator module operable to generate and control electromagnetic (EM) radiation based on the control commands to form an EM signal;
- and
- a feed structure module for conveying the EM signal and having an output port for outputting the EM signal to an electrosurgical instrument, the feed structure having a signal channel for connecting the signal generator module to the output port;
- wherein the at least one memory and the computer program code are configured to, with the at least one processor, cause the remote computing device at least to:
- generate input data based on user input, the input data specifying at least one operating parameter of the signal generator module;
- generate a data packet for wireless transmission to the controller module, the data packet including the at least one operating parameter;
- and
- transmit the data packet to the controller module via a wireless communication channel;
- wherein the control commands are based on the at least one operating parameter of the data packet received by the controller module.
