Hard tube endoscope is not damaged in the process of operation. Although it will contact and bump with human tissues such as muscles, mucous membranes, bones, etc., these bumps are slight and will not cause damage to the endoscope, because it only plays the role of observation, not the force point of other instruments. However, when using other instruments, especially the forceps and scissors with large bite force, it should be noted that the front end of the mirror tube should not extend into the occlusion area of the instrument, so as to avoid injury to the mirror tube. When using this kind of equipment, sometimes doctors extend the endoscope very close to the tissue in order to see clearly the tissue in the occlusal area. When the equipment is occluded, the endoscope does not return and injures the endoscope by mistake. During the operation, if the occlusal mouth of the instrument is all within the scope of observation of the endoscope, such accidents can be avoided.
Some surgical speculums are used in the sheath. When replacing other angle speculums or inserting and unplugging instruments, it should be noted that the movement should be light and the force should not be too strong. Especially in the process of inserting and pulling out the endoscope, when the resistance is encountered, the reason should be carefully found out. If necessary, the endoscope should be pulled out together with the sheath tube, and do not use brute force.
When the endoscope is operated with laser vaporization, high-frequency electric cutting, microwave and other photoelectric technologies, attention should be paid 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 using these instruments for the first time, the surgeon should practice repeatedly, master the relationship between the object distance and the actual object distance in the endoscope image, and confirm the closest distance between the front end of the endoscope and the treatment point, so as to apply them freely in the actual operation.
At present, in the clinical operation of Otolaryngology and orthopedics, planer has been widely used to remove pathological tissue. It has sharp blade, high hardness, fast rotation speed and large torque. If it is cut to the endoscope, the endoscope will be damaged. In this kind of operation, we should pay attention to adjust the speed of flushing and attraction, ensure the clear image of the endoscope at any time and not be covered by blood stain, control the rotating part of the knife head to always be within the scope of observation of the endoscope, when the scope of operation is large, we should stop the rotation of the knife head first, then move the endoscope, then move the knife head under the supervision of the endoscope, and then start the planing after reaching the appropriate position. When it is felt that the planer is working abnormally or the illumination suddenly decreases, it is possible that the endoscope has been damaged, so it should be replaced in time to avoid greater loss.
For general important operations, there should be a set of spare endoscopes and key equipment, which can be replaced calmly when problems are found; if the use of the endoscope with inappropriate angle or non matching equipment is forced to operate, it is also easy to cause damage to the endoscope.
