目的观察复用腔镜手术器械灭菌效果,找出灭菌失败原因,提出防范措施。方法用回顾性调查和现场检测方法对复用腔镜手术器械灭菌效果进行评价。结果连续监测经冲洗式内镜灭菌器灭菌的432件腔镜手术器械,可拆卸不带锁扣管腔器械212件,灭菌合格率为100%;带锁扣管腔器械为220件,有2件不合格,灭菌合格率为99.1%。结论冲洗式内镜灭菌器对带锁扣管腔器械的灭菌存在灭菌失败的可能性,造成灭菌失败的原因为带锁扣的腔镜手术器械,灭菌时锁扣未打开存在灭菌盲点。
Objective To observe the sterilization effect of multi-purpose endoscopic surgical instruments, find out the causes of sterilization failure and propose preventive measures. Methods Retrospective investigation and on-site detection methods were used to evaluate the sterilization effect of multi-use endoscopic surgical instruments. Results Continuous monitoring of 432 endoscopic surgical instruments sterilized with irrigated endoscope sterilizer, removable 212 non-locking instrument with 100% sterility rate; 220 with locking device , 2 failed, the sterilization pass rate was 99.1%. Conclusion Flushing endoscope sterilizer has the possibility of sterilizing the sterilized dental instruments with locking device. The reason of sterilizing failure is the endoscopic surgical instrument with locking. When the sterilizer is not open, the locking device does not open Sterilization blind spots.
