1. There will be energy loss when the needle bar wire contacts the human body, metal material, and concrete floor (table) board, which affects the output strength of the contact. Therefore, the contact area should be as small as possible.
2. When the machine is working, within 3 meters may affect the surrounding TV image, radio listening effect, and a sensitive leakage switch may cause protective action.
3. The single and double electrode treatment needles are connected to plastic parts. It is not suitable to use high temperature sterilization, and it is not suitable to immerse the electrode with a plastic sleeve handle in the disinfectant solution. Short circuit between the electrodes damages the electrodes.
4. If the contact of the surgical electrode is not cleaned in time, it will cause poor contact and fail to achieve the therapeutic effect.
