In recent years, with the continuous development of social economy, endoscope is more and more widely used in our daily life, but many people don't know much about endoscope. In fact, endoscope generally refers to medical instruments that enter the human body through various pipelines to observe the internal conditions of the human body. Let's take a look at some of the main work of endoscope maintenance.
Precautions in use: hard tube endoscopes are rarely damaged during operation. Although they will contact and bump with human tissues such as muscles, mucous membranes and bones, these bumps are slight and will not cause damage to the endoscope, because they only play the role of observation and are not the force point of other instruments. However, when using other instruments, especially forceps and scissors with large bite force, it should be noted that the front end of the mirror tube should not extend into the bite area of the instrument, so as to avoid accidental injury to the mirror tube.
When using this kind of instrument, sometimes the doctor extends the endoscope very close to the tissue in order to see the tissue in the occlusal area clearly. When the instrument occludes, the endoscope does not return and injures the endoscope by mistake. Such accidents can be avoided if all the occlusal openings of the instrument are within the observation range of the endoscope.
Some surgical endoscopes are used in the sheath. When replacing other angle endoscopes or inserting and unplugging instruments, pay attention to light action and do not use too much force. Especially in the process of inserting and removing the endoscope, when it cannot be pulled out due to resistance, carefully find out the reason. If necessary, pull it together with the sheath without brute force.
When the endoscope is operated with laser vaporization, high-frequency electroresection, microwave and other photoelectric technologies, pay attention to the distance between the front end of the endoscope and the treatment point to ensure that the front end of the endoscope is not shocked or burned. When you feel that the planer is working abnormally or the illumination suddenly decreases, the endoscope may have been damaged and should be replaced in time to avoid greater loss.
For general important operations, there should be a set of spare endoscopes and key instruments, which can be replaced calmly when problems are found; It is also easy to cause damage to the endoscope if it is forced to operate with an inappropriate angle endoscope or mismatched instruments.
