肝病為我國國病，肝硬化病人每年有 3~5%轉為肝癌，因此肝癌為我國癌症死亡排名第二位。早期肝癌可用手術切除或局部廓清的方法治療。採用熱能使腫瘤溫度上升至攝氏 50度。廓清腫瘤的方法因對病人傷害極小，於近來受到普遍的應用。但目前國內的熱療器材均仰賴國外進口耗價成本極高。感應加熱熱療 (Hyperthermia Needling System with Induction Heating)原理乃利用不鏽鋼針管插入人體，藉由高頻電源供應器提供之能量使前端線圈產生感應加熱，對腫瘤組織加以熱療燒毀有害部位。本研究結合跨領域人才進行電磁感應加熱模組之構成。包含材料評估、抗沾黏選用與製造技術改良並結合精密加工製造技術以及醫事人員測試評估結果，期望開發為國人適用的電磁感應加熱燒灼器械來降低醫療成本。本研究的目標主要是以感應加熱應用於醫用熱療電磁模組。首先運用軟體模擬出之參數設計測試案例。一般而言，癌細胞 42 ℃以上溫度即可燒毀，經由實驗可得知此醫用熱療電磁模組在空氣中實驗一分鐘所能產生的溫度已高於燒毀癌細胞之溫度。此外，通入醫用熱療電磁模組的頻率為可調，因此可以適用於不同的線圈設計來作為不同腫瘤細胞之治療或組織切除。加上此醫用熱療電磁模組升溫過高，可藉由人機介面控制其電源供應輸出功率。使之對加熱組織產生溫度平衡而控制溫度為定值，或者使醫用熱療電磁模組繼續升溫或降溫。

The purpose of this research is to develop an internal heating system for the common needle of SUS-304 steel in cancer treatment via hyperthermia. The heating ability with the needle via internal induction supplied by an induction heating power with high frequency output at 50-300 kHz, and variable voltage outputs was investigated. The temperature distribution at the entire needle was also considered.
Electromagnetic thermal surgery is a new technique. It applies an electrical current through coils to generate a high frequency magnetic field to heat up magnetic materials in the targeted area. Using this technology, we aim to perform liver resection without bleeding in pigs and rabbits.
Development of a hyperthermia needling system with inner magnetic induction heating. First, we design the test cases to simulate by software. In General, cancer cells can be killed above 42℃. By the experiments, the temperature has been above it in a minute and experiment in the air. In addition, the frequency of module is adjustable, so users can apply different coil design as different treatment of cancer cells. If the temperature is too high, the users can control the power supply by user interface. And the temperature can be constant that balance with cells. Users can control module making it continue heating or lowering the temperature.
