Use and Maintenance of Hard Tube Endoeye

The rigid tube electronic endoeye is by far the most convenient, direct and effective medical device for medical personnel to observe the diseased tissue inside the human body. It has the advantages of high image definition, vivid color, and is easy to operate.

1. Precautions in the use of rigid tube endoeyes

Hard tube endoeyes are rarely damaged during surgery, but when using other instruments, especially forceps and scissors with high occlusal force, care should be taken that the front end of the mirror tube does not protrude into the occlusal area of the instrument, so as not to accidentally damage the mirror tube. When using this type of instrument, sometimes the doctor extends the speculum very close to the tissue in order to see the tissue in the occlusal area. When the instrument is occluded, the speculum is not retracted, and the speculum is accidentally injured. Such accidents can be avoided by making sure that all the occlusal openings of the instruments are within the observation range of the speculum during surgery. Some surgical scopes are used in the sheath. When replacing other angle scopes or inserting and removing instruments, attention should be paid to light movements and not excessive force. Especially in the process of inserting and removing the speculum, when it encounters resistance and cannot be pulled out, the reason should be carefully searched for, and if necessary, it should be pulled out together with the sheath tube, and do not use brute force.

When the endoeye is operated with photoelectric technologies such as laser vaporization, high-frequency electric cutting, and microwave, attention should be paid to the distance between the front end of the endoeye and the treatment point to ensure that the front end of the endoeye will not be electrocuted or burned.

At present, the planer has been widely used in the clinical operation of ENT and orthopedics to remove the diseased tissue. The cutter head is sharp, high hardness, fast rotation speed, and large torque. If the endoeye is cut, the endoeye will be damaged. In this type of operation, attention should be paid to adjusting the speed of flushing and suction, to ensure that the image of the speculum is clear and not blocked by blood stains at any time, and the rotating part of the control cutter head is always within the observation range of the speculum. The cutter head rotates, and then the speculum is moved, and then the cutter head is moved under the surveillance of the speculum, and then starts to plan after reaching the appropriate position. If a speculum with an inappropriate angle or an unsuitable instrument is used for reluctance to perform surgery, it is easy to cause damage to the speculum.

2. Maintenance of rigid tube endoeyes

Rigid tube endoeyes should be kept in a special counter by a special person, put in a special box, and lined with soft sponge or polyurethane foam. All speculum and surgical instruments should be neatly stacked, and should not be placed overlapping each other to ensure that after the lid is closed, the speculum and instruments inside will not collide with each other during transportation.

Because the lens tube of the endoeye is very thin, it will be bent and deformed when it is squeezed, bumped, bent, dropped, etc., resulting in damage to the lens or offset of the optical axis, resulting in unclear or unusable images, so take it out of the box. Or when placing the hard tube endoeye, you should hold it flat with both hands, take it out or put it in gently, and do not lift it up and pull it out. When the speculum is moved in a hard container such as a tray, be careful to place it separately from other instruments, and do not bump it too much, so as not to collide with the speculum. Desiccant should be provided in the packing box to keep it dry.

Ordinary hard tube endoeyes are not resistant to high temperature and high pressure, mainly because the encapsulating glue will deteriorate and deform at high temperature, and the endo eye will open the glue and enter the water, so it cannot be sterilized by high temperature and high pressure methods such as boiling and high-pressure steam.

The damage of most rigid tube endo cameras is caused by inattentive maintenance, bumping, landing and other reasons. There are also problems with the encapsulation glue, packaging technology, and packaging structure of individual manufacturers, resulting in the phenomenon of water ingress and glue opening in the speculum. These can be repaired.

Although a rigid endoeye is a delicate medical device, it is not prone to problems in normal clinical operations or observations. As long as it is used properly, carefully maintained, and carefully maintained, doctors can use it with confidence, and the rigid endoeye will also maximize its benefits.
