醫(yī)用內(nèi)窺鏡是一種常用的醫(yī)療器械，由可彎曲部分、光源及一組鏡頭組成。但內(nèi)窺鏡一旦出現(xiàn)故障，就會(huì)影響患者的治療。下面內(nèi)窺鏡設(shè)備維修人員先來(lái)講講醫(yī)用內(nèi)窺鏡多個(gè)系統(tǒng)的故障處理。

A medical endoscope is a commonly used medical device consisting of a flexible part, a light source, and a set of lenses. However, once the endoscope fails, it will affect the treatment of patients. The endoscope equipment maintenance personnel will first talk about troubleshooting multiple systems of medical endoscope.

人工氣腹系統(tǒng)常見(jiàn)的故障

Common faults of artificial pneumoperitoneum system

（a）壓力顯示不正確。

(a) The pressure display is incorrect.

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。

This is mostly due to damage to the gas pressure sensor. If the machine is designed with a group of multiple differential pressure sensors operating at the same time, usually when one of the sensors is aged or contaminated and cannot work, we need to replace all of this group of sensors, otherwise only one of them will be replaced, and the life of other sensors in the same group is also approaching the critical point.

（b）流量不準(zhǔn)確。

(b) The flow rate is not accurate.

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。

Replace the damaged gas flow sensor. Sometimes the flow rate is calculated by pressure difference, and we need to replace it with a new pressure difference sensor.

（c）設(shè)備漏氣。

(c) Equipment leaks.

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)。

Many cases are caused by aging of the instrument sealing ring. However, there are also reasons for leakage of the mechanical pressure reducing valve and damage to the solenoid valve of the equipment, which are relatively easy to identify and repair.

液體加壓系統(tǒng)常見(jiàn)的故障

Common faults in liquid pressurization systems

（a）蠕動(dòng)泵損壞。

(a) The 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 a gas pressure sensor.

（c）設(shè)備內(nèi)部電路損壞。

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

電凝電切系統(tǒng)常見(jiàn)的故障

Common faults of electrocoagulation and electrocautery 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) Damaged equipment accessories, such as foot switches, negative electrode wires, connecting wires, 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, and bipolar faults are all composed of different circuit modules within the equipment. We can repair or replace the corresponding module circuits based on the symptoms of their faults.".

動(dòng)力、消融系統(tǒng)常見(jiàn)的故障

Common faults of power and ablation systems

（a）動(dòng)力系統(tǒng)主要是創(chuàng)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 wear of the cutting head and problems with the high-energy motor in the planing handle. Motor replacement is selective, and not every type of motor has replacement accessories. 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 main reason for ablation systems in surgical applications is the loss of the blade. Equipment failures are mostly circuit failures, usually starting from the output part.

沖洗吸引系統(tǒng)常見(jiàn)的故障

Common faults in the flushing 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)吸的液體就可以了。

(b) The reason why the device cannot be started up is usually liquid entering the device. It is sufficient to clean up the mistakenly aspirated liquid without burning the relevant components.

所以說(shuō)，對(duì)內(nèi)窺鏡進(jìn)行維修、精細(xì)化管理尤為重要。更為詳細(xì)的內(nèi)容就來(lái)我們網(wǎng)站http://www.eixks.cn咨詢(xún)了解吧！
