内窥镜维修常见的故障有什么?

来源:http://www.jiangrenyiliao.cn/ 发布时间:2025-07-11 浏览量:0

  随着医疗技术发展,医用内窥镜在临床广泛应用,使用中常出现光源、气腹、液体加压等系统故障,掌握相应解决办法可保障设备正常运行。

  With the development of medical technology, medical endoscopes are widely used in clinical practice. System failures such as light source, pneumoperitoneum, and liquid pressurization often occur during use. Mastering corresponding solutions can ensure the normal operation of the equipment.

  光源系统故障中,光线发暗多因灯泡接近使用寿命(氙光灯泡寿命约 500 小时),排除光栅遮挡后更换新灯泡即可,带寿命计时装置的设备更易判断。开机灯泡不亮若非灯泡烧毁,多为高压点火电路元件老化,注意不可用万用表检测脉冲高压。

  In the case of a malfunction in the light source system, dim light is often caused by the bulb approaching its service life (xenon light bulbs have a lifespan of about 500 hours). After eliminating grating obstruction, replacing the bulb with a new one is sufficient. Equipment with a lifespan timer is easier to determine. If the light bulb does not light up when turned on, it is mostly due to the aging of high-voltage ignition circuit components, and it is important not to use a multimeter to detect pulse high voltage.

  人工气腹系统故障需针对性处理:压力显示异常多是气体压力传感器损坏,若为多组压差传感器,建议整体更换避免同组元件陆续失效;流量不准更换流量或压差传感器;设备漏气常因密封圈老化、减压阀或电磁阀损坏,较易判断修复。

  The malfunction of the artificial pneumoperitoneum system needs targeted treatment: abnormal pressure display is often caused by damaged gas pressure sensors. If it is multiple sets of differential pressure sensors, it is recommended to replace them as a whole to avoid the failure of components in the same set one after another; Do not replace flow or differential pressure sensors for flow; Equipment leakage is often caused by aging sealing rings, damage to pressure reducing valves or solenoid valves, which are easier to diagnose and repair.

  液体加压系统常见蠕动泵损坏、液体压力传感器故障(原理同气体传感器)及内部电路损坏,需对应更换部件或检修电路。

  Common damage to peristaltic pumps, liquid pressure sensors (based on the same principle as gas sensors), and internal circuits in liquid pressurization systems require corresponding replacement of components or maintenance of circuits.

  电凝电切系统故障中,脚踏开关、负极板导线等配件易损,直接更换即可;电切、电凝及双极故障,可根据现象维修或更换对应电路模块。

  In the case of faults in the electrocoagulation and cutting system, accessories such as foot switches and negative electrode wires are easily damaged and can be replaced directly; Electric cutting, electrocoagulation, and bipolar faults can be repaired or replaced with corresponding circuit modules according to the symptoms.

  动力系统主要是刨削刀头磨损和手柄内电机问题,电机更换受型号限制,需注重使用保护;消融系统多为刀头损耗,设备故障常为电路问题,可从输出部分排查。

  The main issues with the power system are the wear of the planing blade and the motor inside the handle. The replacement of the motor is limited by the model, and attention should be paid to its protection during use; The ablation system is mostly caused by blade wear, and equipment failures are often circuit problems, which can be investigated from the output part.

  冲洗吸引系统压力或吸力不足,可能是双向泵老化或负压瓶漏气;设备无法开机若因液体误吸,清理干净未损坏部件即可恢复。

  Insufficient pressure or suction in the flushing suction system may be due to aging of the bidirectional pump or leakage of the negative pressure bottle; If the device cannot be turned on due to liquid aspiration, it can be restored by cleaning the undamaged parts.

  为减少故障,建议设专用手术间,由专科护士操作保养,严格遵循术前检查、术中排障、术后维护流程。设备故障优先采取应急维修,可解决约 85% 的中小故障。

  To reduce malfunctions, it is recommended to set up a dedicated operating room, operated and maintained by specialized nurses, and strictly follow the procedures of preoperative examination, intraoperative troubleshooting, and postoperative maintenance. Priority should be given to emergency maintenance for equipment failures, which can solve about 85% of small and medium-sized faults.
