Abstract:
Objective:To analyze the working principle of the ultrasonic scalpel system and its'preventive maintenance mode,so as to reduce the failure rate of the ultrasonic scalpel equipment,and improve its efficiency in clinical surgery.Methods:Based on the working principle of ultrasonic scalpel system,the systemic architecture of the host of ultrasonic scalpel and its clinical application were analyzed,and then,the preventive maintenance effect was summarized.Twenty ultrasonic scalpel equipment from the Medical Engineering Department of Yulin Hospital of Traditional Chinese Medicine were selected as the research objects.According to different maintenance methods,100 surgeries that were completed by 20 ultrasonic scalpels under using conventional maintenance method during January and October 2022 were set as control group,and 120 surgeries that were completed by 20 ultrasonic scalpels under using preventive maintenance method during January and October 2023 were set as intervention group.The actual effect of preventive maintenance was assessed by comparing the failure incidence and repair situations of the ultrasonic scalpel,the efficiency of the operating room,and the satisfaction of the operators between the two groups.Results:The research data showed that the intervention group had significantly lower probabilities in faults,such as dropping ultrasonic scalpel,connection error,and automatic alarm due to improper use,than the control group(x2=12.303,11.345,13.599,13.576,P<0.05),and the number of repairs was significantly less than that of control group.In terms of the efficiency of the operating room,the punctual rate of starting surgery,punctual completion rate,and operational success rate of the intervention group were respectively 94.17%(113/120),95%(114/120)and 95%(114/120),which were significantly higher than those of the control group[78%(78/100),79%(79/100),and 80%(80/100)](x2=12.457,12.969,11.776,P<0.05).Additionally,the satisfaction scores of the operators in terms of convenience of use,use effect,emergency use,and repair timeliness in intervention group were significantly higher than those in control group(t=14.105,19.861,13.104,11.862,P<0.05).Conclusion:The working principle of the ultrasonic scalpel system is complex.The clinical application of preventive maintenance strategy can effectively reduce the failure rate of equipment,and improve the efficiency of surgical operations,and enhance the convenience for operators,thus it has higher values in clinical application and promotion.
