Guidelines and Safety Requirements for Selecting ESU Unit
Guidelines and Safety Requirements for Selecting ESU Unit
High frequency electric knives are widely used in various surgical procedures, which are convenient to use and have good cutting and coagulation functions, as well as high cost-effectiveness. They are widely used for cost control.
The frequency must be stable between 300-1000kHz, and the fundamental wave should be a relatively pure sine wave.
Under no circumstances should the maximum output power exceed 400W, otherwise it will seriously burn the tissue, especially causing damage to the internal tissue.
The withstand voltage of the single and bipolar output terminals to the power supply and ground must be greater than 5000v and 3000v.
The voltage resistance of the output electrode to its connecting cable surface and handle is greater than 3000V
The low-frequency leakage current for patients and the low-frequency auxiliary leakage current for patients must be less than 10ua
At maximum power setting, each output electrode must have a high-frequency leakage current to the ground of less than 150mA
