Description
本發明是有關於一種熱消融裝置，特別是指一種深層感磁熱消融裝置。 The present invention relates to a thermal ablation device, and more particularly to a deep magneto-sensitive thermal ablation device.
現有腫瘤治療方式舉凡微波熱療、射頻消融熱療等，藉以造成局部腫瘤組織的壞死，從而達到對腫瘤治療之目的。然而傳統腫瘤治療所需費用高，甚至會造成病人較大痛楚，使得多數病患尚無法接受腫瘤治療。 Existing tumor treatment methods include microwave hyperthermia, radiofrequency ablation hyperthermia, etc., in order to cause local tumor tissue necrosis, thereby achieving the purpose of tumor treatment. However, the cost of traditional cancer treatment is high, and even the patient suffers from great pain, making it difficult for most patients to receive cancer treatment.
隨著今日醫療水平提升，遂發展出另一適用於腫瘤治療之磁熱腫瘤消融技術，該技術主要是利用交變磁場作用於一感磁針上，使感磁針產生渦電流而轉換成熱，進而燒灼腫瘤組織，這種方式可大幅降低治療費用及病人的痛苦。惟，如何控制其作用電磁場乃是決定治療品質的重要關鍵，所以仍須仰賴研發技術不斷的改良。 With the improvement of medical level today, 磁 developed another magnetocaloric tumor ablation technique suitable for tumor treatment, which mainly uses an alternating magnetic field to act on a magnetic susceptor to convert the susceptor to eddy current and convert it into heat. Burning tumor tissue can greatly reduce the cost of treatment and the suffering of patients. However, how to control the electromagnetic field is the important key to determine the quality of treatment, so it still depends on the continuous improvement of research and development technology.
