As the name suggests: the surgical shadowless lamp is an indispensable equipment used in surgery to illuminate the surgical site. It can clearly observe low-contrast objects at different depths in incisions and body cavities. However, during its use, due to improper installation or the increase of use time, various problems will follow, light boom loose, heavy lamp body sag, JoRadiant explained: the necessity of daily maintenance of surgical shadowless lamp

1. The lamp body boom of the surgical shadowless lamp is disconnected from the cantilever, causing the lamp body to fall.

Solution idea: This is an important problem related to the safe use of shadowless lamps, but also the lessons experienced by installers, here to analyze the reason for the fall of the lamp body to improve the safety awareness of the use of shadowless lamps, the main characteristics of the falling lamp body and the cantilever are: the lamp body boom and cantilever is fixed by the crescent-shaped shrapnel, the shrapnel is in the annular groove of the lamp body boom, so that the lamp body boom can rotate and move. On the cantilever there is a sleeve-like protective ring, its role is to make the crescent-shaped shrapnel rotate inside the cantilever without coming out, that is, to prevent the crescent-shaped shrapnel from popping out, there is a screw hole in the protective ring, through which the protective ring is fixed to the cantilever. When the author found that the lamp body fell off, the protective ring on the cantilever on the site had been displaced above the shrapnel, the shrapnel was still on the cantilever crescent-shaped notch, and the screw was still in the screw hole of the cantilever. After analysis, the protective ring was not fixed by the fixing screw as the cause of this accident.

2. The lamp body of the surgical lamp cannot be positioned, and the left and right swing is unstable.

JoRadiant teaches you the solution: this problem can generally be solved by adjusting the tightness of the rotating screw, which is located on the combination of the cantilever and the fixed cylinder, and the clockwise adjustment is the screwing combiner, and the degree of adjustment does not need to be very large, so that after adjustment, the lamp body will not swing left and right. At the same time, this situation is generally more common in newly used shadowless lamps.

3. The shadowless lamp body sags and cannot be positioned upwards.

JoRadiant helps you solve the problem: on the surface of the vertical cylinder connected to the shadowless lamp cantilever, there is a crescent-shaped cover plate, fixed by two screws, after removing the cover plate, you can see that there is a sheet spring that can move up and down in the cylinder, slowly move the cantilever downward, you will see a cylinder with a screw hole, about 5m thick, use a steel rod with a better fit embedded in the screw hole, adjust the cylinder to the left, make it tight, compress the spring by a certain distance, try to lift the cantilever while adjusting, At the same time, observe whether the sagging phenomenon is improved until the lamp body can maintain a certain height, so that the doctor performing the operation can easily use it. This adjustment method will shorten the up and down stroke of the lamp body, which can only improve the sagging problem to a certain extent, if the adjustment is ineffective, it means that the spring has aged and can only be replaced. Individual old surgical shadowless lamps, due to the long service life, have this phenomenon, of which the lamp body sagging is more than ten centimeters, but after the above method adjustment, it can basically return to normal use.

Summary:

These cases show that when installing and maintaining surgical shadowless lamps, it is necessary to carefully check each joint part, and there is no room for sloppiness. Usually, the lamp body can be swinged with force to see if there is any abnormality, check whether the screws in the key parts are loose, and solve the problem in time. This ensures the safe use of shadowless lamps.
