Abstract

An endoscope apparatus, wherein a microwave irradiator is provided in an endoscope distal end portion. The microwave irradiator includes a pole type antenna and a parabolic reflector which surrounds the antenna and has a parabolic plane. The antenna is directly connected to one end of a microwave-transmitting wire, and the other end of the microwave-transmitting wire is connected to a microwave oscillator of a microwave-generating device by means of a connector. When the endoscope distal end portion is inserted into a coeliac cavity of a patient, medical treatment microwaves having a prescribed radiation energy are conducted to the microwave irradiator through the microwave-transmitting wire. Microwaves emitted from the irradiator are projected on an affected coeliac tissue of a patient to be medically treated, for example, that in which a tumor is grown.
