管腔可视化检测系统评估外来管腔型手术器械的清洗效果研究

目的 分析医院外来管腔型脊柱手术器械清洗的难点，为改进和完善清洗质量控制体系提供依据。方法 选取某院外来脊柱手术器械中的管腔型器械291件，采用腔镜通道检查系统，检查器械在接收时和手工清洗后其管腔内清洗质量，并进行统计分析。结果 接收时管腔器械污染物污染率为89.69%,清洗后污染物污染率为59.45%,主要污染物为组织、污渍、锈渍。带有盲端的器械比两端开口的器械更难清洗，两者组织和污渍的清除率比较，差异均有统计学意义(均P<0.05)。结论 外来管腔型脊柱手术器械较难清洗，应优化清洗流程，并将管腔内表面清洗质量纳入考核体系。

Evaluation of cleaning effect of loaner luminal surgical instruments by endoscopic lumen visual inspection system

Objective To analyze the difficulties in the cleaning of loaner luminal spinal surgical instruments, and provide basis for improving and perfecting the cleaning quality control system. Methods 291 loaner luminal spinal instruments in a hospital were selected, and the endoscopic lumen inspection system was used to check the cleaning quality of lumen of instruments when they were received and after manual cleaning, statistical analysis was performed. Results The contamination rates of contaminants were 89.69% and 59.45% at receiving time and after cleaning of luminal instruments, the main contaminants were tissue, stain and rust. Instruments with blind ends were more difficult to be cleaned than those with openings at both ends, there were significant differences in tissue and stain removal rates between two groups (both P < 0.05). Conclusion It is difficult to clean the loaner luminal spinal surgical instruments, so the cleaning process should be optimized and cleaning quality of inner surface of lumen should be included in the assessment system.
