摘要
本文阐述了微波前列腺治疗仪的原理和设计,采用频率为915MHz的微波对前列腺进行热疗。特殊设计的固态微波源和表面冷却技术,使加热区仅局限在前列腺上。特制的治疗导管和辐射器,可以实现经尿道或经直肠进行治疗。所用的热敏传感器的测温精度可达±0.1℃,运用微型计算机对治疗的全过程进行自动测温、控温,并实时记录、显示、打印治疗参数和病例资料管理。
The therapy principle and design of microwave prostate hyperthermia are described. This apparatus uses 915MHz microwave treatment for the prostate. The solid state microwave source and surface cooling system of special design only heats the prostate. The specially designed Foley duct and microwave radiator can be used for treatment by transurethral or transrectal. The temperature is measured and monitered automatically, and the measured data are recorded, displayed and printed in real-time by a microcomputer. The accuracy of thermosensor measurements is ±0.1℃.
