Arthroscopy is a rod-shaped optical instrument with a diameter of about 5mm to observe the internal structure of the joint. It is an endoscope for the diagnosis and treatment of joint diseases. As a medical device that also enters the human body, its cleaning and disinfection are very important. The following is a set of professional procedures for arthroscopic cleaning and disinfection.

　　清洗

　　clean

　　清洗是一个非常重要的环节，是保证效果的首要条件。

　　Cleaning is a very important link and the first condition to ensure the effect of disinfection and sterilization.

　　镜头是整个关节镜系统中为之昂贵，也是特容易损伤的仪器，所以必需清洗、妥善保管。其清洗办法较其他器械不同，不能用毛刷以及任何锋利利器去碰击，以免划伤镜头，只能在活动水下冲洗，清洗终了后用柔软塑料泡沫盒放置保管。

　　Lens is an expensive and easily damaged instrument in the whole arthroscopic system, so it must be cleaned first and kept properly. The cleaning method is different from other instruments, and can not be brushed with any brush or any sharp tool to avoid scratching the lens. It can only be washed under the moving water. After the cleaning is finished, it is placed in a soft plastic foam box.

　　镜头之外的其他器械要用专用关节镜清洗刷清洗，清洗刷要将各种器械狭缝内的残留组织肃清掉；各种管腔通道用高压水枪冲洗，以便将各种管道中残留的组织冲净；其他器械的轴节局部要拆开清洗，使清洗更为彻底。保证器械的清洁，为展开下面的工作奠定根底。

　　Other instruments outside the lens shall be cleaned with special arthroscopic cleaning brush, which shall remove the residual tissue in the slit of various instruments; various lumen channels shall be washed with high-pressure water gun, so as to clean the residual tissue in various pipelines; the coupling parts of other instruments shall be disassembled for cleaning to make the cleaning more thorough. Ensure the cleaning of the equipment and lay the foundation for the following work.

　　浸泡

　　soak

　　将清洗后的关节镜器械全部浸泡在40℃～60℃的多酶溶液中5～10min。浸泡时将各种器械的阀门完整翻开，使多酶溶液可以完整灌注到各种管腔内，从而到达多酶溶液浸泡的目的。同时，应留意线缆接头的帽盖要旋紧，以免进水形成仪器短路等不用要的损坏。

　　All the cleaned arthroscopic instruments were immersed in the multienzyme solution at 40 ℃ ~ 60 ℃ for 5 ~ 10min. When soaking, the valves of all kinds of instruments are completely opened, so that the multi enzyme solution can be completely poured into all kinds of lumens, so as to achieve the purpose of multi enzyme solution soaking. At the same time, it should be noted that the cap of cable connector should be tightened to avoid unnecessary damage such as short circuit of instrument caused by water inflow.

　　过滤

　　filter

　　将浸泡后的一切器械置于盛有蒸馏水的容器中再次浸泡，去除物体上的微粒及热源。

　　Put all the soaked instruments into a container containing distilled water and soak them again to remove the particles and heat source on the object.

　　再次清洗

　　Clean again

　　依照上述清洗办法，再次将关节镜器械在活动水下冲洗，目的是使多酶溶液完整冲净，从而到达器械的干净，为发明良好的条件。

　　According to the above cleaning method, the arthroscopic instrument is rinsed under the active water again, so as to make the multi enzyme solution completely rinsed, so as to achieve the cleanness of the instrument, and create good conditions for disinfection and sterilization.

　　枯燥

　　Boring

　　保证每一种仪器的枯燥，是环氧乙烷必需具备的前提。

　　To ensure the dryness of each instrument is the prerequisite for ethylene oxide sterilization.

　　（1）先将各种器械的外表用枯燥柔软的巾擦干，镜头用特地的布料擦拭；

　　(1) First, dry the appearance of various instruments with dry and soft treatment towel, and wipe the lens with special cloth;

　　（2）再用吹风器，或者在烘烤箱内将其管腔内的水滴烘干，留意摄像头、巧合器不能用持续高温烘烤，由于在高温条件下，会将镜片接口处的硅胶熔解，形成巧合器进水起雾,视野含糊。

　　(2) Then use a hair dryer or dry the water drops in the lumen of the oven. Pay attention that the camera and the coincidence device cannot be baked with continuous high temperature. Under high temperature conditions, the silica gel at the lens interface will be melted, forming the coincidence device with water and fog, and the field of vision is ambiguous.

　　保养与检查

　　Maintenance and inspection

　　确保仪器在下次手术运用时的平安性。

　　Ensure the safety of the instrument during the next operation.

　　（1）将各种线缆衔接在关节镜仪器上,开机检查摄像头的明晰度以及镜头能否形成了磨损;

　　(1) Connect all kinds of cables on the arthroscopic instrument, turn on the machine to check the clarity of the camera and whether the lens is worn;

　　（2）检查各种器械的轴节处能否灵敏,线缆的接头处能否光滑;

　　(2) Check whether the couplings of various instruments are sensitive and the joints of cables are smooth;

　　（3）将检查结果停止记载,做到心中有数,以备日后查询。

　　(3) Stop recording the inspection results and know them well for future reference.

　　打包

　　pack

　　将各种器械分类整理，使其有序排列。

　　Classify and arrange all kinds of instruments in order.

　　（1）镜头要放置在特地的泡沫盒子内，轻拿轻放；

　　(1) the lens should be placed in a special foam box and gently handled.

　　（2）摄像头要用棉质物品包裹打包，防止碰撞；

　　(2) The camera shall be wrapped and packed with cotton materials to prevent collision;

　　（3）光纤导线不能打折，只能盘曲地放置，其弯曲水平不能超越90°，以免将光纤折断，并用含有软泡沫的盒子包裹好；

　　(3) optical fiber conductors can not be discounted, and can only be placed in a bent place. The bending level can not exceed 90 degrees, so as not to break the optical fibers and wrap them in boxes containing soft foam.

　　（4）停止打包，并在包布上标明“请勿挤压、碰撞”等字样，再次预防在搬运过程中形成仪器的损伤。

　　(4) Stop packing, and mark the words "do not squeeze, collision" on the cloth, so as to prevent the damage of the instrument in the process of handling again.

　　

　　Disinfection and sterilization

　　运用的方式是环氧乙烷。但需留意，当浓度到达3%～10%（30000PPM）时，EO即燃；急性吸入可惹起呼吸道刺激；皮肤接触可惹起皮炎和水泡；消化道接触具有腐蚀性；眼睛接触可惹起严重刺激形成损伤等。

　　The disinfection method used is ethylene oxide disinfection. However, it should be noted that when the concentration reaches 3% - 10% (30000ppm), EO will burn; acute inhalation can cause respiratory irritation; skin contact can cause dermatitis and blisters; digestive tract contact is corrosive; eye contact can cause serious irritation and damage.
