Feasibility Study of Microwave Energy Devices Composed of Dielectric Waveguides

Microwave surgical energy device is excellent energy device for coagulation of biological tissue and can reduce the generation of surgical smoke during surgery. However, since they directly touch biological tissue during surgery, they are disposed of after single use for hygienic reasons. Therefore, it was considered that if microwave energy devices could be fabricated using dielectric waveguides without metallic parts, it would be possible to simplify the device structure and reduce waste in medical devices. In this study, numerical analysis confirmed that microwave surgical energy device composed of dielectric waveguide can be used for heating biological tissue.
