電池驅動、可拋針頭、無線智聯網之手持式電磁消融刀

Abstract

本研究所開發的兩種熱消融刀有別於目前臨床上普遍的熱消融技術，分別為磁熱消融和電熱消融，皆以電池驅動達到無線，在治療過程中不釋放電荷於組織上無安全疑慮。磁熱消融刀以電磁感應加熱技術，迅速將金屬磁針溫度上升至高溫，針對小範圍腫瘤治療，而電熱消融刀利用奈米碳之高效電熱轉換特性進行加熱，依據治療範圍的大小替換不同針具。本文以COMSOL Multiphysics 5.6進行模擬，觀察針具的升溫狀況，以及豬肝內部受到針具影響的溫度變化，並與實際消融範圍進行比對，加以驗證熱療效果。The two thermal ablation knives developed in this research are different from the current common clinical thermal ablation techniques. They are magnetic thermal ablation and electrothermal ablation. Both are battery-driven to achieve wireless, and there is no safety concern about not releasing charge on the tissue during the treatment. The magnetic thermal ablation knife uses electromagnetic induction heating technology to rapidly increase the temperature of the metal magnetic needle to high temperature, which is aimed at small-scale tumor treatment. The electrothermal ablation knife uses the high-efficiency electrothermal conversion characteristics of nanocarbon to heat, and replaces different needles according to the size of the treatment area.This article uses COMSOL Multiphysics 5.6 to simulate, observe the heating condition of the needle and the temperature change inside the porcine liver affected by the needle, and compare it with the actual ablation range to verify the effect of hyperthermia.
