Abstract:
A method of controlling an electric surgical operation apparatus for treating a living body using high-frequency energy, comprising:a first step of detecting whether or not a treatment unit is in contact with the living body on the basis of a physical quantity of the high-frequency energy supplied to the treatment unit; a second step of bringing a high-frequency energy generating circuit that supplies the high-frequency energy to the treatment unit so as to have a first operating state in which the high frequency energy generating circuit is enabled to supply first high-frequency energy increasing a temperature of the treatment unit to a temperature that allows the treatment unit to treat the living body, in case the result of the first step is that the treatment unit is in contact with the living body; a third step of determining whether or not the temperature of the treatment unit has increased enough to treat the living body by means of said first high-frequency energy generated by the high-frequency energy generating circuit on the basis of the physical quantity of the high-frequency energy supplied to the treatment unit; and a fourth step of changing a setting of the high-frequency energy generating circuit so as to have a second operating state in which the high-frequency energy generating circuit is enabled to supply second high-frequency energy which is lower than the first high-frequency energy and which allows the high-frequency energy generating circuit to treat the living body, in case the temperature of the treatment unit has increased enough to treat the living body in the third step.
