故障一：接通电源，电压表就有50伏以上读数。蛇出偏大。这种故障易被忽视。危险的是该机器一通电：就进人预备状态而此时医生还误认为按纽未按下，电刀就不会有电能输出，因此如用电刀在病人身上比划，则可能引发医疗事故。由于电刀的负极板是和机箱相连的，机箱往往放在金属
Fault 1: The power supply is turned on, and the voltmeter has a reading of 50 volts or more. The snake is too big. This kind of failure is easily overlooked. The danger is that once the machine is powered on: it enters the preparatory state and the doctor mistakenly believes that the electric knife will not have power output when the button is not pressed. Therefore, if the electric knife is used to make a gesture on the patient, it may cause a medical accident. . Since the negative electrode plate of the electrocautery is connected with the chassis, the chassis is often placed on the metal
