ELECTROSURGICAL GENERATOR WITH DUAL OUTLETS

An Electrosurgical generator including an inverter unit generating a high-frequency alternating voltage to be supplied to at least two output sockets for connection of electrosurgical instruments. The inverter unit is a multilevel inverter. It includes a plurality of co-operating inverter cells which are connected in a cascaded manner in a first state and being split into at least two groups (I, II) in a second state. The inverter unit is selectively switchable between said first and second state. Each group is assigned one of the output sockets and feeds its HF voltage thereto. This enables simultaneous controlling of the distinct groups and their HF output. Thereby, unwanted interference patterns can be avoided. Uncontrolled low-frequency beat can be largely suppressed, allowing improved control of thermal energy and cutting power. Quality of the work performed can be increased which is beneficial for the patient.
