Development of intelligent multi\|pole RF ablation therapeutic instrument based on the theory of RF local destruction is introduced. The equipment adopts master machine and slave machine architecture. The master machine is a PC; the slave machine is an 89C52 singlechip mainly responsible for temperature measurement and control. Data transmission between master and slave machines is carried out by RS232 serial port communication. The instrument has two kinds of power control modes:manual control and auto control. While working at auto control mode, the equipment adopts improved PID temperature control algorithm, with which the problem of precision deterioration of temperature control due to tumor tissue characteristics variation caused in the process of heating was solved. It ensures homogeneous and smooth RF heating of tumor foci.Intelligent case history database management system (DBMS) carries out case history registration, treatment data archiving, classified query and treatment report printing functions, which provide doctors with reliable data for making treatment plans. Animal experiments demonstrated that the equipment works stably and reliably, and has good therapeutic results, which indicates good clinical application value.
