醫(yī)療用內(nèi)窺鏡主要性能參數(shù)

Main performance parameters of medical endoscopes

機械性能：

Mechanical performance:

①密封性：內(nèi)窺鏡的密封性關系到成像質(zhì)量，如密封不好就容易滲水，破壞光學系統(tǒng)，影響觀察。通水閥鏡鞘與膀胱鏡的錐體配合處應密合，在1min內(nèi)滲水應不超過5滴，否則配合不好容易漏水影響手術。

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連接部位牢固性

③ Durability of connection parts

絕緣性能：

Insulation performance:

主要是電子內(nèi)窺鏡，相關電氣隔離部位的絕緣結(jié)構，如與CCD攝像頭相配接的目鏡罩冷光源接口導光索等相關附件的絕緣性能。

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.

絕熱性能：

Insulation performance:

在醫(yī)用內(nèi)窺鏡中，由于內(nèi)窺鏡是侵入性檢查工具，為了避免內(nèi)窺鏡工作的時候?qū)θ梭w的傷害，現(xiàn)在一般都采用冷光源，在光輸出口設置紅外濾光片，最。大限度地限制紅外光的輸出。

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.

內(nèi)窺鏡測漏流程

Endoscopic leak detection process

內(nèi)鏡蓋好防水帽掛于主機上

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

打開光源開關

Turn on the light source switch

將測漏器插入主機

Insert the leak detector into the host

檢查測漏器壓力

Check the pressure of the leak detector

測漏器與鏡子相連接

The leak detector is connected to the mirror

充氣3秒鐘看鏡子前頭是否漏氣

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

將鏡子完全放入水中

Completely immerse the mirror in water

使各旋鈕均處于放松狀態(tài)并旋轉(zhuǎn)大小旋鈕，檢查有無漏氣(約30秒

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

將鏡子取出擦干

Take out the mirror and wipe it dry

測漏器與主機分離(約30秒，目的是放掉鏡內(nèi)的氣體

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

測漏器與鏡子分離，操作完畢。

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

二清理先端頭

Two cleaning tips

．用抬鉗座夾住先端頭，蓋玻璃面朝上，將1mm直徑的鋼棒對著鉗子管出口位金屬接頭，用小錘敲擊，直到把金屬接頭連著部分鉗子管往下脫出，接著用小號一字批將殘余在鉗子管安裝孔里的AB膠清理干凈；

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;

．將合適的鋼棒插進空心的像束金屬部，用斜口鉗夾住露出先端頭外的金屬部，把金屬頭完全夾取出來。

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.

．用磨尖的小號批，在放大鏡下清理像束安裝孔壁的AB膠，（小心不能碰到物鏡，以免刮花物鏡）直到干凈后把物鏡倒出來，（有時需要用力敲擊先端頭才能倒出來）然后一手用鑷子夾住物鏡，一手用鑷子夾鏡頭紙，沾酒精把貼在物鏡上的光學膠拭擦掉，直至鏡片干凈無塵。

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.

．用合適轉(zhuǎn)頭的手動轉(zhuǎn)把光束安裝孔里的光纖清理出來，當轉(zhuǎn)到接近底的時候放慢以免磨花光束蓋玻璃。

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.

．用鏡頭紙沾酒精清理像束及光束安裝孔。

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