隨著科學(xué)技術(shù)的發(fā)展，醫(yī)用內(nèi)窺鏡已經(jīng)被廣泛的應(yīng)用于醫(yī)療領(lǐng)域，它是人類(lèi)窺視、治療人體內(nèi)器官的重要工具之一。醫(yī)用內(nèi)窺鏡故障難免也會(huì)出現(xiàn)，下面醫(yī)用內(nèi)窺鏡故障維修小編為您講解下。

With the development of science and technology, medical endoscope has been widely used in the medical field. It is one of the important tools for human beings to peep and treat the internal organs of the human body. It is inevitable that medical endoscope failures will occur. The following medical endoscope failure maintenance manual will explain it to you.

（1）光源系統(tǒng)常見(jiàn)的故障

(1) Common faults of light source system

（a）光線(xiàn)發(fā)暗。排除了是光柵遮擋的原因外，基本可以肯定是燈泡接近使用壽命，更換新燈泡則可。氙光燈泡的使用壽命一般設(shè)計(jì)在500小時(shí)，如果光源系統(tǒng)有壽命計(jì)時(shí)裝置，這個(gè)問(wèn)題就很容易解決。

(a) The light is dim. It is ruled out that the light bulb is close to its service life, and it can be replaced with a new light bulb. The service life of xenon light bulb is generally designed to be 500 hours. If the light source system has a life timer, this problem can be easily solved.

（b）開(kāi)機(jī)燈泡不亮。如果排除了燒掉燈泡這個(gè)原因的話(huà)，那么問(wèn)題常常就出在主機(jī)高壓點(diǎn)火電路部分，因?yàn)殚_(kāi)機(jī)的時(shí)候機(jī)器會(huì)產(chǎn)生上萬(wàn)伏特的脈沖高壓，元件會(huì)老化得特別快。注意此時(shí)不能用萬(wàn)用表去檢查脈沖高壓。

(b) The power on bulb does not light up. If the reason of burning out the bulb is ruled out, the problem is often in the high-voltage ignition circuit of the host, because the machine will generate tens of thousands of volts of pulse high voltage when it is turned on, and the components will age very quickly. Note that you cannot use a multimeter to check the pulse high voltage at this time.

（2）人工氣腹系統(tǒng)常見(jiàn)的故障

(2) Common faults of artificial pneumoperitoneum system

（a）壓力顯示不正確。這多是氣體壓力傳感器損壞，如果機(jī)器設(shè)計(jì)有一組多個(gè)壓差壓力傳感器同時(shí)工作的，一般一個(gè)老化或者污染無(wú)法工作的時(shí)候，我們要把這組傳感器全部更換，否則只換其中一個(gè)，其他的同組的傳感器壽命也接近臨界了。

(a) The pressure display is incorrect. This is mostly due to the damage of gas pressure sensors. If the machine is designed to have a group of multiple differential pressure sensors working at the same time, generally when one of them is aging or polluted and cannot work, we should replace all of these sensors, otherwise only one of them will be replaced, and the life of other sensors of the same group will also be near the critical point.

（b）流量不準(zhǔn)確。氣體流量傳感器損壞更換即可。有時(shí)候是通過(guò)壓差來(lái)計(jì)算流量的，這時(shí)候我們就要更換新的壓差傳感器。

(b) The flow is not accurate. If the gas flow sensor is damaged, replace it. Sometimes the flow is calculated by differential pressure. At this time, we need to replace a new differential pressure sensor.

（c）設(shè)備漏氣。很多情況是器械密封圈老化而引起的。但也有設(shè)備機(jī)械減壓閥漏氣和電磁閥損壞的原因，這個(gè)比較容易判斷出并對(duì)其進(jìn)行修復(fù)。

(c) The equipment leaks air. Many cases are caused by the aging of the device sealing ring. However, there are also reasons for leakage of mechanical pressure reducing valve and damage of solenoid valve, which can be easily identified and repaired.

（3）液體加壓系統(tǒng)常見(jiàn)的故障

(3) Common faults of liquid pressurizing system

（a）蠕動(dòng)泵損壞。

(a) Peristaltic pump is damaged.

（b）液體壓力傳感器損壞。其原理基本與氣體壓力傳感器相同。

(b) The liquid pressure sensor is damaged. Its principle is basically the same as that of the gas pressure sensor.

（c）設(shè)備內(nèi)部電路損壞。

(c) The internal circuit of the equipment is damaged.

（4）電凝電切系統(tǒng)常見(jiàn)的故障

(4) Common faults of electric coagulation and electric cutting system

（a）設(shè)備配件損壞。如腳踏開(kāi)關(guān)，負(fù)極板導(dǎo)線(xiàn)，連接導(dǎo)線(xiàn)等常用的易損配件。

(a) The equipment accessories are damaged. Such as foot switch, negative plate wire, connecting wire and other commonly used vulnerable accessories.

（b）電切、電凝，雙極故障。在設(shè)備內(nèi)部，這些部分都由不同的電路模塊組成。我們可以根據(jù)其表現(xiàn)的故障現(xiàn)象對(duì)相應(yīng)的模塊電路進(jìn)行維修或更換。

(b) Electric cutting, electrocoagulation, bipolar fault. Inside the equipment, these parts are composed of different circuit modules. We can repair or replace the corresponding module circuit according to the fault phenomenon.

（5）動(dòng)力、消融系統(tǒng)常見(jiàn)的故障

(5) Common failures of power and ablation systems

（a）動(dòng)力系統(tǒng)主要是刨削刀頭的磨損和刨削手柄中的高能電機(jī)出現(xiàn)問(wèn)題，而電機(jī)的更換是有選擇性的，并不是每種電機(jī)都有更換配件的。因此在消毒和使用過(guò)程中要分外注意保護(hù)。

(a) The power system is mainly caused by the wear of the planer head and the problem of the high-energy motor in the planer handle. The replacement of the motor is selective, and not every motor has replacement parts. Therefore, special attention should be paid to protection during disinfection and use.

（b）消融系統(tǒng)在手術(shù)應(yīng)用中主要是刀頭的損耗。而設(shè)備故障多為電路故障，一般從輸出部分著手。

(b) The ablation system is mainly the loss of knife head in surgical application. However, most equipment failures are circuit failures, generally starting from the output part.

（6）沖洗吸引系統(tǒng)常見(jiàn)故障

(6) Common faults of flushing and suction system

（a）壓力或者吸力不足。設(shè)備中的雙向泵老化,或者負(fù)壓瓶漏氣。

(a) Insufficient pressure or suction. The two-way pump in the equipment is aging, or the negative pressure bottle leaks.

（b）設(shè)備無(wú)法開(kāi)機(jī),一般多為液體進(jìn)入設(shè)備,在沒(méi)燒壞相關(guān)部件的情況下清理干凈被錯(cuò)吸的液體就可以。

(b) The equipment cannot be started. Generally, the liquid enters the equipment. It is OK to clean up the liquid sucked by mistake without burning the relevant parts.

醫(yī)用內(nèi)窺鏡在使用中常會(huì)出現(xiàn)光源系統(tǒng)常見(jiàn)的故障、人工氣腹系統(tǒng)常見(jiàn)的故障、液體加壓系統(tǒng)常見(jiàn)的故障、電凝電切系統(tǒng)常見(jiàn)的故障、動(dòng)力、消融系統(tǒng)常見(jiàn)的故障、沖洗吸引系統(tǒng)常見(jiàn)故障，要提前做好預(yù)防準(zhǔn)備工作，更多事項(xiàng)或問(wèn)題就來(lái)我們網(wǎng)站http://foxnewsss.com咨詢(xún)吧。
