Abstract：Objective Ultrashort wave therapy apparatus has been widely used in clinical as an adjuvant therapy. It is necessary
for medical equipment maintenance engineers to be familiar with the ultrashort wave therapy apparatus’s working principle and
maintenance of common faults to ensure it’s normal operation. Methods According to the troubleshooting course of a special short
circuit fault case of ultrashort wave therapy apparatus fault, we analyzed and narrowed the fault range via combining with fault
phenomenon, working principle, circuit principle and the actual circuit. At last, the fault hidden trouble was detected by component
test. Results After changing the performance of the components, the ultrashort wave therapy apparatus ran normally. Conclusion
This method is feasible and the maintenance cost is low. This research can offer reference for the maintenance of ultrashort wave
therapy apparatus, as well as provide maintenance direction for medical equipment maintenance engineers.
