Abstract
An electric medical apparatus according to the present invention performs an incising treatment automatically after the coagulating treatment has been performed without a necessity for an operator to perform another operation between the two treatment operations when the incising treatment performs after a coagulating treatment. The electric medical apparatus comprises a CPU, a waveform generating circuit, an amplifier and an output control unit to supply an output for performing the coagulating treatment to a treatment device and an output for performing the incising treatment to the treatment device. The impedance of a living tissue with which the treatment device is brought into contact is measured and calculated by a voltage sensor, a current sensor and an impedance calculating portion. In accordance with a result of the calculation performed by the impedance calculating portion, an output from an electric knife body is, by the CPU, switched to the output for the incising treatment after the coagulating treatment has been performed.
