KYKY YT300C高频电刀的研制开发

Research and development of KYRY YT300C HF electrosurgical unit

研制成功的KYKY YT300C高频电刀主要由高频电压输出部分、功率测量部分和安全检测部分组成。采用了先进的PWM、双CPU技术，用大功率VMOS场效应管作为功率器件，功耗小能量转换效率高，RF输出功率稳定，具有很好的切凝效果。

This paper introduces the KYRY YT300C electrosurgical unit composed of three parts of HF voltage output power measurement and security examination． With the application of high－power VMOS FET as the power component and advanced technologies including PWM and Bi－CPU it has low wasted work high efficiency of energy transition constant power of RF output and good effect of incision and coagulation． It has been proven by experiment that it is comparable with advanced foreign one．
