电刀是利用高频电流通过机体时在组织中产生热效应进行工作的。因电流的频率越高对人体的危险性越小,手术使用电刀是比较安全的。主要的意外事故是电力负极板处烫伤以及电刀引起心电图电极处皮肤的烫伤。作者单位1978～1984年实施心电图监护
Electric knife is the use of high-frequency current through the body when the thermal effects in the organization to work. Due to the higher the frequency of the current human body the less dangerous, the use of electric knife surgery is more secure. The main accidents are burns on the negative plate of the power supply and burns on the skin at the electrode of the electrocardiogram caused by the electric knife. The author unit from 1978 to 1984 implementation of ECG monitoring
