Abstract：Two fault cases of REM loop negative plate monitoring system frequent alarm and electric cut without output power in
hand control mode of Valleylab Force FX high frequency electric knife were analyzed, checked and maintained. The troubleshooting
course showed the basic principle of REM loop negative plate monitoring system and hand control related control circuit, and offered
consult to similar faults. Regular and active maintenance can decrease faults incidence of electric knife, reduce down time, improve
work efficiency and guarantee safety of patients and medical staff.
