鏡的操作部包括水氣按鈕、吸引按鈕、大小旋鈕、S蓋、操作把手、鉗子管開口閥、鉗子管接口、水氣管接口、調角度裝置及牽引鋼絲的鏈條。

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：水氣按鈕。它是控制水和氣的開關按鈕，把按鈕裝在鏡子上，用手堵住按鈕頂部的小孔是送氣，氣壓來自冷光源的壓縮氣泵；而用手把按鈕壓下去是送水，水來自送水瓶上的蒸餾水。送水送氣主要作用是清洗先端部的鏡頭表面。

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：吸引按鈕。它是控制吸引的開關按鈕，把吸引泵的吸引連接管連接在鏡子導光部的吸引接口上，活檢口用活檢帽蓋住，防止漏氣，鏡子插上吸引按鈕，接通吸引泵電源，用手指按下吸引按鈕就能進行吸引了，廢液從鏡子先端部的鉗子口通過鉗子管和吸引管被排到吸引泵的儲存瓶里。

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：旋鈕。胃腸鏡有兩個旋鈕，大旋鈕負責控制上下角度，小旋鈕負責控制左右角度，大小旋鈕都有一個鎖，有英文字母F標識，當調整到一定角度時逆時針板上這個鎖時，就能把角度鎖在該位置上，方便醫師進行該部位的診斷。

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。操作把手是醫師平時操作鏡子手抓的部位，把手上標有鏡子的型號，如GIF-Q260,還有顏色的標識，表示鉗子管內徑的尺寸，如黃色代表此鏡子鉗子管是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蓋。指的是操作部背面的一個蓋，因為蓋子都是不規則的形狀，所以叫S蓋。蓋子上都會印有、型號或序列號。昨天提到把手的顏色標示通常有白色：1.2mm、藍色：2或2.2mm、綠色：2.6mm、黃色：2 .8或3.2mm、橙色：3.7或4.2mm的鉗子管道。

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：牽引鋼絲的部件。有三種，奧林巴斯用鏈條，這是它的，其它不能采用。富士能用骨輪鋼絲，賓得用線輪。骨輪鋼絲和線輪容易斷，特別是結腸鏡，所以這兩種維修該部件的很常見。

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：鋼絲固定件。該部件是焊在鋼絲的末端，與牽引鋼絲的部件如鏈條、線輪等連接著，起到拉動鋼絲的作用。如鏡子漏水或焊接不牢，鋼絲固定件就容易脫焊導致無角度，這是一種常見故障。

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，該部件焊在螺旋管末端，卡在操作部支撐架里，共四個固定件，起到鏡子打角度時，插入管拉直的支撐作用。如該固定件脫焊，打角度時插入管就會像蛇形樣抽起。

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：鉗子管開口閥，又叫K立管，形狀像K字母。它是鉗子管和吸引管的連接金屬管，是下活檢的入口，通常印有鉗子管的內徑尺寸，如圖標示的2.8k，表示此K立管連接的鉗子管是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，該是吸引按鈕的插座，也是清洗時消洗刷進去刷洗鉗子管和吸引管的入口，所以該吸引座容易被摩擦造成缺口，吸引時無力且漏液。

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：調角度裝置。該部件由螺絲桿與滑板組成，滑板前端與鏈條頭部卡住，當逆時針調節螺絲桿，角度就變大，反之變小，這就實現了調角度的功能。

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.

賓得軟鏡調角度裝置。該裝置是利用一個滑片來限定角度的，如圖，松開兩顆螺絲后，將滑片往左推，角度變小；往右推，角度變大。調整好角度后擰緊螺絲即可。此種裝置微調性差。

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.

富士能軟鏡的調角度裝置。該裝置是利用拉桿的原理來實現角度的調整。松開三顆螺絲，把拉桿拉長，角度變小；把拉桿推進去，角度變大。調整完擰緊螺絲。

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：水氣座裝置。該部件是放置水氣按鈕的連接座，共有四條管道，分別各有一條水管和一條氣管入，一條水管和一條氣管出。如圖所示：右邊兩條帶螺旋片保護的是入口管，上面的是氣管，下面的是水管；左邊兩條短管是出口管，長的是氣管，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.
