Medical endoscope system is mainly composed of equipment system and surgical instrument system. Surgical instrument system is mainly classified by department or operation name. There are endoscopes, special instruments, surgical instruments and disposable surgical consumables used in various departments. I won't give a detailed introduction here. Next, we mainly discuss the structure of the equipment system.

在設備系統中我們通常可以分為：攝像顯像系統，影像記錄系統，光源系統，人工氣腹系統，液體加壓系統，電凝電切系統，動力消融系統，沖洗吸引系統等等。

In the equipment system, we usually can be divided into: camera imaging system, image recording system, light source system, artificial pneumoperitoneum system, liquid pressure system, electrocoagulation system, dynamic ablation system, flushing and suction system, etc.

（1）攝像顯像系統：該系統包括顯示器和攝像機。顯示器有常規的CRT和液晶兩種，攝像機有單CCD和3CCD兩種。現在使用客戶多是液晶顯示器配3CCD攝像器。

(1) Camera imaging system: the system includes display and camera. There are two kinds of displays: CRT and LCD, and two kinds of cameras: single CCD and 3CCD. Now most of the customers use LCD with 3CCD camera.

（2）影像記錄系統：現在很多醫院都選擇以電腦為基礎的圖文工作站。該系統分兩部分：電腦硬件和圖文采集軟件。

(2) Image recording system: now many hospitals choose computer-based graphic workstation. The system consists of two parts: computer hardware and image acquisition software.

（3）光源系統：又稱冷光源。冷光源燈泡中充有鹵素和氙氣兩種，其輸出功率為70-400W。現在300W氙光源是主流的產品。其突出特點是光線強烈，色溫5600-6000k，與太陽光類似，涵蓋了從紫外線到紅外線的整個波段。

(3) Light source system: also known as cold light source. The cold light bulb is filled with halogen and xenon, and its output power is 70-400w. Now 300W xenon light source is the mainstream product. Its outstanding feature is strong light, color temperature 5600-6000k, similar to sunlight, covering the entire band from ultraviolet to infrared.

（4）人工氣腹系統：將氣腹機與二氧化碳鋼瓶連接好，并旋開鋼瓶上的閥門，然后開啟氣腹機，根據手術的需要，選擇壓力預設值，當腹腔內壓力超過或低于設定值時，全自動二氧化碳氣腹機可自動開始或停止注氣。

(4) Artificial pneumoperitoneum system: connect the pneumoperitoneum machine with the carbon dioxide cylinder, loosen the valve on the cylinder, and then turn on the pneumoperitoneum machine. According to the needs of the operation, select the preset pressure. When the intra-abdominal pressure exceeds or falls below the set value, the automatic carbon dioxide pneumoperitoneum machine can automatically start or stop gas injection.

（5）液體加壓系統：關節泵、膨宮泵和膀胱泵等系統主要是用于通過液體加壓成腔，然后再通過器械在腔體內進行手術。

(5) Liquid pressure system: Joint pump, uterine distention pump and bladder pump are mainly used to form cavity by liquid pressure, and then operate in the cavity by instruments.

（6）電凝電切系統：在普通開放性手術中和微創手術中都常使用高頻電刀。

(6) Electrocoagulation and electrosurgical resection system: high frequency electrotome is often used in common open surgery and minimally invasive surgery.

（7）動力消融系統：在鼻竇鏡和關節鏡手術中多會使用的是動力刨削系統和離子消融刀，這兩種設備雖然不菲，但是它們卻大大地縮短了術中時間和降低了手術風險。

(7) Dynamic ablation system: dynamic planing system and ion ablation knife are often used in endoscopic sinus surgery and arthroscopic surgery. Although these two devices are expensive, they greatly shorten the operation time and reduce the operation risk.

（8）沖洗吸引系統：設備沖洗流速少應達到1L/min。

(8) Flushing suction system: the equipment flushing flow rate should be less than 1L / min.
