ELECTROSURGICAL GENERATOR

An electrosurgical generator including an inverter unit generating HF energy and a high-voltage connection supplying the HF energy to an output socket for an electrosurgical instrument. The high-voltage connection includes a base module with a distribution unit and at least one connection port. The distribution unit comprises a HF distribution line and data communication wiring, both being supplied to the at least one connection port for which a sub module is provided connecting to the HF and the data signals and supplying the output socket. Thereby electrical connections and data communications are established at once. Consequently, inserting a different sub module allows for simplified alteration of type and variant of the generator. A newly developed version of the sub module may just be inserted into the connection port without any need of alteration of the base module. Modernization and updating is facilitated.
