镜的操作部包括水气按钮、吸引按钮、大小旋钮、S盖、操作把手、钳子管开口阀、钳子管接口、水气管接口、调角度装置及牵引钢丝的链条。

The operating part of the mirror includes a water vapor button, an attraction button, a size knob, an S cover, an operating handle, a clamp tube opening valve, a clamp tube interface, a water vapor tube interface, an angle adjustment device, and a chain for pulling steel wires.

操作部零部件1：水气按钮。它是控制水和气的开关按钮，把按钮装在镜子上，用手堵住按钮顶部的小孔是送气，气压来自冷光源的压缩气泵；而用手把按钮压下去是送水，水来自送水瓶上的蒸馏水。送水送气主要作用是清洗先端部的镜头表面。

Operating part 1: Water and gas button. It is a switch button that controls water and air. Place the button on a mirror and block the small hole at the top of the button with your hand to supply air. The pressure comes from the compressed air pump of the cold light source; Pressing the button down with your hand is to send water, which comes from distilled water on the water bottle. The main function of water and air delivery is to clean the surface of the lens at the front end.

操作部零部件2：吸引按钮。它是控制吸引的开关按钮，把吸引泵的吸引连接管连接在镜子导光部的吸引接口上，活检口用活检帽盖住，防止漏气，镜子插上吸引按钮，接通吸引泵电源，用手指按下吸引按钮就能进行吸引了，废液从镜子先端部的钳子口通过钳子管和吸引管被排到吸引泵的储存瓶里。

Operating part 2: Attraction button. It is a switch button that controls the attraction, connecting the suction connection tube of the suction pump to the suction interface of the mirror light guide. The biopsy port is covered with a biopsy cap to prevent air leakage. The mirror is plugged in with the suction button, connected to the power supply of the suction pump, and the suction button can be pressed with fingers to attract. Waste liquid is discharged into the storage bottle of the suction pump through the clamp mouth at the front end of the mirror through the clamp tube and the suction tube.

操作部零部件3：旋钮。胃肠镜有两个旋钮，大旋钮负责控制上下角度，小旋钮负责控制左右角度，大小旋钮都有一个锁，有英文字母F标识，当调整到一定角度时逆时针板上这个锁时，就能把角度锁在该位置上，方便医师进行该部位的诊断治疗。

Operating part 3: Knob. Gastrointestinal endoscopy has two knobs, the large knob is responsible for controlling the up and down angles, and the small knob is responsible for controlling the left and right angles. Both the large and small knobs have a lock, marked with the English letter F. When adjusted to a certain angle, the counterclockwise plate can lock the angle in that position, making it convenient for physicians to diagnose and treat the area.

操作部零部件4：操作把手。操作把手是医师平时操作镜子手抓的部位，把手上标有镜子的型号，如GIF-Q260,还有颜色的标识，表示钳子管内径的尺寸，如黄色代表此镜子钳子管是2.8mm。

Operating part 4: Operating handle. The operating handle is the part where the doctor usually handles the mirror. The handle is labeled with the model of the mirror, such as GIF-Q260, and there is also a color mark indicating the size of the inner diameter of the clamp tube. For example, yellow indicates that the clamp tube of this mirror is 2.8mm.

操作部零部件5：S盖。指的是操作部背面的一个盖，因为盖子都是不规则的形状，所以叫S盖。盖子上都会印有品牌、型号或序列号。昨天提到把手的颜色标示通常有白色：1.2mm、蓝色：2或2.2mm、绿色：2.6mm、黄色：2 .8或3.2mm、橙色：3.7或4.2mm的钳子管道。

Operating part 5: S cover. It refers to a cover on the back of the operating section, which is called an S cover because the covers are all irregularly shaped. The brand, model, or serial number will be printed on the lid. Yesterday, it was mentioned that the color markings for handles usually include white: 1.2mm, blue: 2 or 2.2mm, green: 2.6mm, yellow: 2.8 or 3.2mm, orange: 3.7 or 4.2mm pliers for pipes.

操作部零部件6：牵引钢丝的部件。有三种，奥林巴斯用链条，这是它的专利，其它品牌不能采用。富士能用骨轮钢丝，宾得用线轮。骨轮钢丝和线轮容易断，特别是结肠镜，所以这两种品牌维修该部件的很常见。

Component 6 of the operation department: a component for pulling steel wires. There are three types, Olympus uses chains, which is its patent and cannot be used by other brands. Fuji can use bone wheel steel wire, Pentax can use wire wheel. Bone wheel steel wire and wire wheel are prone to breakage, especially for colonoscopes, so it is common for these two brands to repair this component.

操作部的零部件7：钢丝固定件。该部件是焊在钢丝的末端，与牵引钢丝的部件如链条、线轮等连接着，起到拉动钢丝的作用。如镜子漏水或焊接不牢，钢丝固定件就容易脱焊导致无角度，这是一种常见故障。

Component 7 of the operation department: steel wire fixing parts. This component is welded to the end of the steel wire and connected to components such as chains and pulleys that pull the steel wire, playing a role in pulling the steel wire. If the mirror leaks water or the welding is not firm, the steel wire fixing parts are prone to detachment and lack of angle, which is a common fault.

操作部零部件8：螺旋管固定件，该部件焊在螺旋管末端，卡在操作部支撑架里，共四个固定件，起到镜子打角度时，插入管拉直的支撑作用。如该固定件脱焊，打角度时插入管就会像蛇形样抽起。

Operating part 8: Spiral tube fixing component, which is welded to the end of the spiral tube and clamped in the support frame of the operating part. There are four fixing components in total, which play a supporting role in straightening the insertion tube when the mirror is angled. If the fixing part is detached, the inserted tube will be pulled out like a snake when angled.

操作部的零部件9：钳子管开口阀，又叫K立管，形状像K字母。它是钳子管和吸引管的连接金属管，是下活检的入口，通常印有钳子管的内径尺寸，如图标示的2.8k，表示此K立管连接的钳子管是2.8mm的。

Component 9 of the operation department: clamp tube opening valve, also known as K riser, shaped like the letter K. It is the connecting metal tube between the forceps tube and the suction tube, which is the entrance for the lower biopsy. It is usually printed with the inner diameter size of the forceps tube, as shown in the figure at 2.8k, indicating that the forceps tube connected to this K-tube is 2.8mm.

操作部的零部件10:吸引座，该是吸引按钮的插座，也是清洗消毒时消洗刷进去刷洗钳子管和吸引管的入口，所以该吸引座容易被摩擦造成缺口，吸引时无力且漏液。

Component 10 of the operation department: suction seat, which is the socket for the suction button and also the inlet for the disinfectant brush to brush the clamp tube and suction tube during cleaning and disinfection. Therefore, the suction seat is prone to friction causing gaps, making it weak and leaking during suction.

操作部的零部件11：调角度装置。该部件由螺丝杆与滑板组成，滑板前端与链条头部卡住，当逆时针调节螺丝杆，角度就变大，反之变小，这就实现了调角度的功能。

Component 11 of the operation department: angle adjustment device. This component consists of a screw rod and a skateboard. The front end of the skateboard is stuck with the head of the chain. When the screw rod is adjusted counterclockwise, the angle increases, and vice versa, it decreases, achieving the function of angle adjustment.

宾得软镜调角度装置。该装置是利用一个滑片来限定角度的，如图，松开两颗螺丝后，将滑片往左推，角度变小；往右推，角度变大。调整好角度后拧紧螺丝即可。此种装置微调性差。

Pentax soft mirror angle adjustment device. The device uses a slider to limit the angle, as shown in the figure. After loosening two screws, push the slider to the left, and the angle decreases; Push to the right, the angle increases. After adjusting the angle, tighten the screws. This type of device has poor fine-tuning performance.

富士能软镜的调角度装置。该装置是利用拉杆的原理来实现角度的调整。松开三颗螺丝，把拉杆拉长，角度变小；把拉杆推进去，角度变大。调整完拧紧螺丝。

Fujineng's angle adjustment device for soft mirrors. This device utilizes the principle of a pull rod to achieve angle adjustment. Loosen three screws, elongate the pull rod and reduce the angle; Push the pull rod in and increase the angle. After adjusting, tighten the screws.

操作部的零部件12：水气座装置。该部件是放置水气按钮的连接座，共有四条管道，分别各有一条水管和一条气管入，一条水管和一条气管出。如图所示：右边两条带螺旋片保护的是入口管，上面的是气管，下面的是水管；左边两条短管是出口管，长的是气管，短的是水管。

Component 12 of the operation department: water and gas seat device. This component is the connection seat for placing the water and gas button, with a total of four pipes, each with one water pipe and one air pipe in and one water pipe and one air pipe out. As shown in the figure: The two pipes on the right with spiral protection are the inlet pipes, the upper one is the trachea, and the lower one is the water pipe; The two short pipes on the left are the outlet pipes, the long one is the trachea and the short one is the water pipe.
