医疗用内窥镜主要性能参数

Main performance parameters of medical endoscopes

机械性能：

Mechanical performance:

①密封性：内窥镜的密封性关系到成像质量，如密封不好就容易渗水，破坏光学系统，影响观察。通水阀镜鞘与膀胱镜的锥体配合处应密合，在1min内渗水应不超过5滴，否则配合不好容易漏水影响手术。

① Sealing: The sealing of the endoscope is related to the imaging quality. If the sealing is not good, it is easy to leak water, damage the optical system, and affect observation. The fitting between the sheath of the water valve and the cone of the cystoscope should be tight, and the water leakage should not exceed 5 drops within 1 minute. Otherwise, poor fitting may cause water leakage and affect the surgery.

②表面粗糙度

② Surface roughness

③连接部位牢固性

③ Durability of connection parts

绝缘性能：

Insulation performance:

主要是电子内窥镜，相关电气隔离部位的绝缘结构，如与CCD摄像头相配接的目镜罩冷光源接口导光索等相关附件的绝缘性能。

Mainly the insulation structure of electronic endoscopes and related electrical isolation parts, such as the insulation performance of accessories such as the cold light source interface light guide cable of the eyepiece cover matched with CCD cameras.

绝热性能：

Insulation performance:

在医用内窥镜中，由于内窥镜是侵入性检查工具，为了避免内窥镜工作的时候对人体的伤害，现在一般都采用冷光源，在光输出口设置红外滤光片，。大限度地限制红外光的输出。

In medical endoscopes, as endoscopes are invasive examination tools, in order to avoid harm to the human body during the operation of endoscopes, cold light sources are generally used, and infrared filters are installed at the light output outlet. Maximize the output of infrared light.

内窥镜测漏流程

Endoscopic leak detection process

内镜盖好防水帽挂于主机上

Cover the endoscope with a waterproof cap and hang it on the main unit

打开光源开关

Turn on the light source switch

将测漏器插入主机

Insert the leak detector into the host

检查测漏器压力

Check the pressure of the leak detector

测漏器与镜子相连接

The leak detector is connected to the mirror

充气3秒钟看镜子前头是否漏气

Inflate for 3 seconds to check if there is any air leakage in the front of the mirror

将镜子完全放入水中

Completely immerse the mirror in water

使各旋钮均处于放松状态并旋转大小旋钮，检查有无漏气(约30秒

Place all knobs in a relaxed state and rotate the large and small knobs to check for air leakage (approximately 30 seconds

将镜子取出擦干

Take out the mirror and wipe it dry

测漏器与主机分离(约30秒，目的是放掉镜内的气体

The leak detector is separated from the host for approximately 30 seconds to release the gas inside the mirror

测漏器与镜子分离，操作完毕。

The leak detector is separated from the mirror and the operation is complete.

二清理先端头

Two cleaning tips

．用抬钳座夹住先端头，盖玻璃面朝上，将1mm直径的钢棒对着钳子管出口位金属接头，用小锤敲击，直到把金属接头连着部分钳子管往下脱出，接着用小号一字批将残余在钳子管安装孔里的AB胶清理干净；

Clamp the front end of the pliers with the lifting clamp seat, cover the glass face upwards, and place a 1mm diameter steel rod towards the metal joint at the outlet of the pliers tube. Use a small hammer to strike until the metal joint is partially detached from the pliers tube. Then, use a small batch to clean up the remaining AB glue in the installation hole of the pliers tube;

．将合适的钢棒插进空心的像束金属部，用斜口钳夹住露出先端头外的金属部，把金属头完全夹取出来。

Insert a suitable steel rod into the hollow bundle of metal parts, clamp the exposed metal part with diagonal pliers, and completely remove the metal head.

．用磨尖的小号批，在放大镜下清理像束安装孔壁的AB胶，（小心不能碰到物镜，以免刮花物镜）直到干净后把物镜倒出来，（有时需要用力敲击先端头才能倒出来）然后一手用镊子夹住物镜，一手用镊子夹镜头纸，沾酒精把贴在物镜上的光学胶拭擦掉，直镜片干净无尘。

Using a sharpened small batch, clean the AB adhesive on the mounting hole wall of the image beam under a magnifying glass (be careful not to touch the objective lens to avoid scratching the objective lens) until it is clean. Then, pour out the objective lens (sometimes requiring strong tapping of the tip to pour it out), and use tweezers to clamp the objective lens with one hand, and use tweezers to clamp lens paper with the other hand. Dip alcohol to wipe off the optical adhesive attached to the objective lens until the lens is clean and dust-free.

．用合适转头的手动转把光束安装孔里的光纤清理出来，当转到接近底的时候放慢以免磨花光束盖玻璃。

Use a suitable manual rotation head to clean the optical fibers from the installation hole of the beam. When the rotation is close to the bottom, slow down to avoid grinding the glass of the beam cover.

．用镜头纸沾酒精清理像束及光束安装孔。

Clean the image beam and beam mounting holes with lens paper dipped in alcohol.
