Leakage Burn and Electric Appliance Security from High-frequency Electrotome / 医疗卫生装备

The electrotome is a kind of medical surgical operation instrument, which can be applied to incision and electrocoagulation of tissues. From the aspect of circuit structure, high-frequency electrotome is divided into three types, that is, spark type, valve type and semiconductor type. The third one poses its future at miniaturization, high power and intelligentization. As the development of electrotome, some surgical accidents come up, such as electrical leakage, leakage burn and electric appliance security. So more and more attention is paid to the application security of high -frequency electrotome. The test method and some burn and leakage examples of electrotome are introduced and analyzed in the paper.
