Characteristics of an antenna generating a localized heating region for robotic surgery

[摘要] Microwave energy devices can coagulate biological tissues without generating surgical smoke. Therefore, we proposed the double-loop antenna for miniaturization and generating a localized heating to adapt microwave energy device for robotic surgery. The double-loop antenna consists of a double-loop and rod for changing the total antenna length. In order to evaluate the heating characteristics of our proposed antenna, the current distribution was calculated. As a result, it is confirmed that the combination of the double-loop and 10mm rod can achieve uniform heating.
