To provide a treatment device capable of turning microwaves into treatment energy, recognizing the geometric enlargement of the treatment area in a direction orthogonal to the axis of an energy supplying tool for treatment and controlling the output of microwaves.
The microwaves for the treatment of a microwave oscillation part 2 are impressed to a microwave piercing applicator 5 and radiated from a microwave radiation antenna part 6 at the tip to the side of a viable tissue 7 to which it is pierced. At this time, high frequency signals from an HF oscillation part 13 are transmitted through a surface applicator 8 connected with electrodes 9 for measurement separately arranged in the direction orthogonal to the axis of the microwave piercing applicator 5, the impedance of the viable tissue 7 between the electrodes is measured by a cauterization surface monitor part 11 and a cauterization inner part monitor part 12 and the cauterization range of the direction orthogonal to the axis of the microwave piercing applicator 5 is recognized in a cauterization range recognition part 14 by that. A recognized result is sent to a control part 15 and the output of the microwaves for the treatment is controlled.
