在使用喷淋清洗机清洗手术器械时，关节、咬合处等复杂结构部位容易残留污染物（如血液、组织等）是清洗质量控制的重点、难点。

　　When using a spray cleaning machine to clean surgical instruments, complex structural parts such as joints and bite points are prone to residual pollutants (such as blood, tissue, etc.), which is the focus and difficulty of cleaning quality control.

　　装载时须将器械的关节完全打开，咬合部分打开，可拆卸的部分拆卸后装载清洗，同时、器械的摆放要避免遮挡和重叠，确保所有部位能够充分暴露在喷淋水流下。

　　When loading, the joints of the equipment must be fully opened, the bite part must be opened, and the detachable parts must be disassembled before loading and cleaning. At the same time, the placement of the equipment should avoid obstruction and overlap, ensuring that all parts can be fully exposed to the spray water flow.

　　但喷淋清洗真的能彻底清洗干净吗？

　　But can spray cleaning really thoroughly clean?

　　我们做个实验观察一下：

　　Let's conduct an experiment to observe:

　　将器械关节打开涂抹模拟污染物后固定在篮筐底部，放入清洗消毒器内，先进行喷淋清洗、再进行超声波清洗，用视频记录清洗全过程。

　　Open the joint of the instrument and apply simulated pollutants, then fix it at the bottom of the basket and place it in a cleaning and disinfection device. First, perform spray cleaning, followed by ultrasonic cleaning, and record the entire cleaning process with video.

　　经过喷淋清洗后，肉眼可见器械表面的模拟污染物基本去除，但关节处仍有模拟污染物残留。

　　After spray cleaning, the simulated pollutants on the surface of the instrument visible to the naked eye were basically removed, but there were still residual simulated pollutants at the joints.

　　再进行超声波清洗，清洗过程中可观察到模拟污染物逐渐分解、剥离。

　　Further ultrasonic cleaning can be performed, during which simulated pollutants can be observed gradually decomposing and peeling off.

　　结论：

　　Conclusion:

　　喷淋清洗机能够快速高效的去除器械表面的污渍，但细小缝隙中的污渍去除能力不足，超声波清洗能够弥补这一问题。故建议：常规器械定期开展超声波处理，以去除关节处、咬合齿口部等顽固的污渍。

　　Spray cleaning machine can quickly and efficiently remove stains on the surface of instruments, but its ability to remove stains in small gaps is insufficient. Ultrasonic cleaning can make up for this problem. Therefore, it is recommended to regularly perform ultrasonic treatment on conventional instruments to remove stubborn stains such as joints and bite teeth.
