Abstract: A microwave device capable of increasing an amount of heat generated at the tip end thereof. The microwave device having a central conductor that transmits microwaves, an insulator covering the central conductor, and an external conductor covering the insulator. The central conductor is exposed to the outside from a tip end of a microwave irradiation part for the first time, and an externally exposed part of the exposed central conductor is bent toward the base end side of the microwave emitting unit so as to be along the external conductor.

Abstract: A microwave induction heating device includes microwave oscillation means (100) for oscillating a microwave so that an object is heated by the induction heating of the microwave oscillated from the microwave oscillation means (100). The microwave oscillation means (100) is configured in such a manner that the frequency of the microwave oscillated from the microwave oscillation means (100) can be changed.

Abstract: A reaction device including a microwave oscillation means for generating microwaves; holding containers for individually holding multiple samples collected from collection targets (e.g., human targets, etc.); a microwave irradiation container on which each of the holding containers can be individually loaded; a temperature sensor for detecting the temperature of a sample held in a holding container or of the interior of the microwave irradiation container; and a microwave control means for varying the microwaves generated by the microwave oscillation means on the basis of the temperature detected by the temperature sensor. The microwave irradiation container includes: a microwave introduction port for introducing the microwaves generated by the microwave oscillation means into the microwave irradiation container; and ring-shaped patterns for irradiating each of the holding containers with the microwaves introduced from the microwave introduction port.

Abstract: The present application discloses an invention of a surgical operation method using microwave characterized in that microwaves are radiated to bio-tissue from a monopolar type operating electrode attached to the tip of a coaxial cable for transmitting microwaves, and an operation of coagulation, hemostasis or transection is performed on the bio-tissue with the use of thermal energy generated from the reaction of the microwaves on the bio-tissue. The bio-tissue can be operated in an easy, safe and bloodless manner. Therefore, the present method can be utilized for an operation on a parenchymatous organ having a great blood content or for coagulation or transection on a parenchymatous tumor.According to the present method, there can be performed an operation on liver cancer which has been conventionally regarded as very difficult.Apparatus for embodying the present method can be economically manufactured in a small size.
