为进行脑肿瘤的加热治疗提供依据,本实验采用自制金鹰植入体磁感应加热装置,对兔脑组织进行局部加热研究。该加热线置由高频电流发生器、电磁感应线圈和金属磁性针(植入体)组成.在加热时,通过调整加热装置中各部分相应的参数,使植入组织内的金属磁性针产生足够的治疗温度(49℃),在加热过程中温度相对稳定,金属磁性针周围兔脑组织温度明显递减,邻近脑组织的热损伤局限.增加金属磁性针的数量进行排阵加热,可扩大加热范围,提高组织内温度分布的均质性,增强加热效果.
In order to provide a basis for the heating treatment of brain tumors, this experiment uses a magnetic induction heating device made of gold eagle implants to conduct local heating studies on rabbit brain tissue. The heating wire is composed of a high-frequency current generator, an electromagnetic induction coil, and a metal magnetic needle (implant). During heating, by adjusting the corresponding parameters of each part of the heating device, the metal magnetic needle implanted in the tissue produces a sufficient therapeutic temperature (49° C.), the temperature is relatively stable during the heating process, and the temperature of the rabbit brain tissue around the metal magnetic needle is Significantly diminished, near the thermal damage limitations of brain tissue. Increasing the number of metal magnetic needles for array heating can expand the heating range, increase the homogeneity of the temperature distribution within the tissue, and enhance the heating effect.
