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.
