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 go into details here. Let's mainly discuss the structure of the equipment system.

在設(shè)備系統(tǒng)中我們通?？梢苑譃椋簲z像顯像系統(tǒng)，影像記錄系統(tǒng)，光源系統(tǒng)，人工氣腹系統(tǒng)，液體加壓系統(tǒng)，電凝電切系統(tǒng)，動力消融系統(tǒng)，沖洗吸引系統(tǒng)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 pressurization system, electrocoagulation and electric cutting system, dynamic ablation system, flushing and suction system, etc.

（1）攝像顯像系統(tǒng)：該系統(tǒng)包括顯示器和攝像機。顯示器有常規(guī)的CRT和液晶兩種，攝像機有單CCD和3CCD兩種?，F(xiàn)在高端的使用客戶多是液晶顯示器配3CCD攝像器。

(1) Camera imaging system: the system includes a display and a camera. There are two kinds of display: CRT and LCD. There are two kinds of camera: single CCD and 3CCD. Now the high-end customers are mostly LCD with 3CCD camera.

（2）影像記錄系統(tǒng)：現(xiàn)在很多醫(yī)院都選擇以電腦為基礎(chǔ)的圖文工作站。該系統(tǒng)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(tǒng)：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(xiàn)在300W氙光源是主流的產(chǎn)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 source 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(tǒng)：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(jù)手術(shù)的需要，選擇壓力預(yù)設(shè)值，當(dāng)腹腔內(nèi)壓力超過或低于設(shè)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, unscrew the valve on the cylinder, and then open the pneumoperitoneum machine. According to the needs of the operation, select the preset pressure. When the pressure in the abdominal cavity exceeds or is lower than the set value, the full-automatic carbon dioxide pneumoperitoneum machine can automatically start or stop gas injection.

（5）液體加壓系統(tǒng)：關(guān)節(jié)泵、膨?qū)m泵和膀胱泵等系統(tǒng)主要是用于通過液體加壓成腔，然后再通過器械在腔體內(nèi)進行手術(shù)。

(5) Liquid pressure system: Joint pump, dilatation pump, bladder pump and other systems are mainly used to form a cavity through liquid pressure, and then operate in the cavity through instruments.

（6）電凝電切系統(tǒng)：在普通開放性手術(shù)中和微創(chuàng)手術(shù)中都常使用高頻電刀。

(6) Electrocoagulation and electrotomy system: high frequency electrotome is often used in general open surgery and minimally invasive surgery.

（7）動力消融系統(tǒng)：在鼻竇鏡和關(guān)節(jié)鏡手術(shù)中多會使用的是動力刨削系統(tǒng)和離子消融刀，這兩種設(shè)備雖然價格不菲，但是它們卻大大地縮短了術(shù)中時間和降低了手術(shù)風(fēng)險。

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

（8）沖洗吸引系統(tǒng)：設(shè)備沖洗流速最少應(yīng)達到1 L/min。

(8) Flushing suction system: the equipment flushing flow rate shall be at least 1 L / min.
