Abstract:Objective To analyze statistically the insulation failure of laparoscopic surgical instruments and propose the
countermeasures to ensure the safety of patients and operators. Methods Three hundred and ninety-nine pieces of laparoscopic
surgical instruments were tested for insulation performance by visual inspection method and instrument inspection method,
respectively. The insulation performance differences between the two methods were compared to analyze the causes of insulation
failure. Through the method of questionnaire survey, the clinical status of laparoscopic surgical instrument insulation performance
was investigated. Results The failure rates of the insulation layer of laparoscopic surgical instruments detected by visual
measurement method and instrument detection method were 38.6% and 44.86%, respectively. The insulation layer failure could occur
in the front, middle, end and hand parts of the instrument. There were significant differences in the types and locations of insulation
faults detected by the two methods (P<0.05). Conclusion The insulation failure of laparoscopic surgical instruments is common. The
combination of visual and instrument detection methods can improve the fault detection rate of insulating layer of instruments and
ensure the safety of patients and medical personnel.
