Claim:
An electric operation system comprising: at least one electric treatment instrument for therapeutically treating tissue of a living body; a plurality of instrument drivers connected to the at least one electric treatment instrument; a system controller for controlling the plurality of instrument drivers; a reader for reading a plurality of operation parameters of the at least one electric treatment instrument connected to the plurality of instrument drivers; and a control parameter range determining section for determining a control parameter range, where the plurality of instrument drivers are controllable by the system controller, on the basis of the plurality of operation parameters read by the reader, wherein the at least one electric treatment instrument is driven by a first instrument driver and a second instrument driver of the plurality of instrument drivers, and the control parameter range determining section gives a high priority to a specific operation parameter when the operation parameters of the electric treatment instrument connected to the plurality of instrument drivers are set, and sets a range of the specific operation parameter to which the high priority is given on the basis of information from the second instrument driver other than the first instrument driver corresponding to the specific operation parameter.
