If the connection between the neutral plate and the host is broken, an audible and visual alarm will occur. The electrode plate must be in direct contact with the patient's bare skin, the closer to the operation area, the better, and if possible, the contact area should be as large as possible.
2.2 Selection and operation of each working state of unipolar
The working status of the high-frequency electric knife is indicated by the unipolar electric cutting indicator and the unipolar electric coagulation indicator. The yellow is electric cutting and the blue is electric coagulation. For unipolar electrocutting and unipolar electrocoagulation, the buzzer will emit different sounds. The level of the sound volume can be set by adjusting the buzzer volume up key and buzzer volume down key. When the high-frequency energy output indicator light is on, it indicates that the high-frequency voltage is present. In the unipolar mode, the high-frequency electrosurgical unit has two working states: unipolar electrosurgical cutting and unipolar electrocoagulation, while unipolar electrosurgical cutting includes two states of unipolar pure cutting and unipolar mixed cutting.
Insert the hand-controlled knife handle, neutral plate, foot switch and other accessories to be used into the corresponding hand-controlled knife handle socket, neutral plate socket, and foot switch socket of the high-frequency electric knife.

Mixed cutting working state.
2.2.3 Unipolar Coagulation
Press the blue electrocoagulation button of the hand-controlled knife handle or step on the blue electrocoagulation pedal of the foot switch, the unipolar electrocoagulation indicator light is on, at this time, the electrosurgical knife is in the unipolar electrocoagulation working state.
2.3 Selection and operation of manual working mode
Insert the sterilized hand-controlled knife handle three-pin plug into the hand-controlled knife handle socket.
Through the cutting and coagulation power setting buttons [cutting power adjustment up key, cutting power adjustment down key, coagulation power adjustment up key, coagulation power adjustment down key], set the power display to an appropriate value, surgery Doctors can choose unipolar pure cutting, unipolar mixed cutting and unipolar electrocoagulation. (The greater the value displayed on the power display, the greater the output power of the high-frequency electric knife, and vice versa.)
The hand-controlled knife handle can be selected by the surgeon during the operation by pressing the button on the hand-controlled knife handle with the index finger to select different working modes. The one near the electrode tip is the excitation monopolar electrocutting button, and the one far away from the electrode tip is the excitation monopolar electrocoagulation button. . If the buttons are pressed at the same time, the electrosurgical unit will be in the unipolar electrocoagulation mode (the control logic prohibits the two functions from working at the same time, and the priority belongs to the electrocoagulation mode).
2.4 Selection and operation of foot control working mode
Set the power indicator to the appropriate value through the unipolar electrocutting and unipolar electrocoagulation power setting keys [cutting power adjustment up key, cutting power adjustment down key, electrocoagulation power adjustment up key, and electrocoagulation power adjustment down key Value, insert the sterilized hand-controlled knife handle and foot switch into the corresponding hand-controlled knife handle socket and foot switch socket.
