Modern medicine has reached a high level of patient care. A large number of surgical interventions are performed with minimal traumatic consequences for patients, and therefore, the recovery period can take only a few days. The discovery and further development of endoscopy technology played an important role in the development of surgery and diagnostics.
Endoscopy is a method of diagnosis and surgical intervention using an endoscope - a device that is inserted into the body without damaging the skin - through the oral cavity, anus, etc. Using a sensor with a video camera, the doctor assesses the condition of an organ by examining the image on the screen monitor. The whole process is carried out with minimal trauma and virtually no pain.
In order to properly carry out medical manipulations, it is recommended to use high-level equipment. One of the main elements of such equipment is the monitor.In this article, we will tell you what endoscopy monitors are, how to choose the best model and what to look for in order not to make mistakes when choosing. We will also make a rating of high-quality video monitors based on the reviews of doctors working with them.

Since this equipment is used to treat people, and it is important for a doctor to see a real picture of the state of health, a large number of requirements are imposed on medical video monitors, unlike household ones. So, the main difference is that the medical device has higher characteristics compared to the usual one. In most of these devices, the screen resolution allows you to view the picture without using additional devices for scaling. According to the recommendations of experts, the best monitors have a resolution of up to 4096 × 2560.
Medical displays are designed in such a way that they can be rotated in any direction, including horizontal position. European standards require clinics to install only specialized equipment in operating rooms that has passed all relevant checks and meets international quality standards (has a corresponding certificate).This is due to the fact that human life, which is the highest value, may depend on the result of the operation of such a device. Due to the fact that the doctor may not see anything on the monitor, the patient may be misdiagnosed, because of which the wrong treatment will subsequently be prescribed, with all the ensuing consequences.
Most medical video monitors are designed to provide a wide viewing angle. Devices with this feature allow you to see the image from any side, regardless of how the user stands in relation to it. Also, this function will be convenient when holding medical consultations, when several specialists can simultaneously view the picture without being directly in front of the device. The optimal viewing angle is 150 degrees or more.
The brightness value also plays an important role. Since visibility is limited during endoscopic examination, it is important to distinguish the halftones of adjacent tissues. In order to conduct a correct assessment of the state of a particular organ, it is necessary to use a display that transmits realistic colors and has a wide range of brightness. Modern devices are programmed in such a way as to adjust the optimal color transmission before switching on, depending on what kind of lighting in the office, as well as the state of the environment (including air temperature). This feature allows you to evaluate even unsuccessful frames that can be obtained during the study.
In terms of shades of gray, medical video monitors are also superior to household ones. The number of shades displayed is typically 1024, compared to 256 for a standard monitor.This range provides contrast and a visible difference from one area to another. It is recommended to choose video monitors with a brightness of 3,000 cd/m2 or more.
The hue of the backlight of the device is no less important than other parameters. Is this due to the fact that the examination often uses several devices located side by side? to enlarge the picture. And if such devices are made by different manufacturers, they may differ in color, which can make it difficult for a doctor to read the images. Even from the same manufacturer, two devices can differ significantly in shades. In order to avoid discrepancies, many manufacturers sell such products in pairs, indicating that they can only be used together. In rare cases, the backlight can be adjusted, but this feature is found only in expensive models.
Before using the monitor, it must be properly calibrated. This task can only be entrusted to a specialist who has sufficient skills and knows the features of a particular model. He will be able to properly calibrate the device so that it transmits the best image. Calibration is a grayscale display adjustment. Such a setting is required not only to get maximum visibility, but also to ensure that the image transmitted to monitors in other organizations has the same appearance as on the source. It should be taken into account that calibration is recommended to be carried out at least once every six months, since the set parameters may go astray over time. The calibration procedure also includes adjusting the backlight tone, since over time the lamps begin to shine yellow, and the backlight turns yellow.
Unfortunately, no matter how high-quality the display is, it is not able to improve the image of a low-quality source, and therefore such manipulations should be carried out by a specialist of a high category.
This product is intended for completing medical offices and has the corresponding features that distinguish it from household competitors - high color reproduction, increased contrast, and faster response speed. For the convenience of the user, the device can not only be installed on a horizontal surface, but also mounted on the wall. The product is offered in two colors - black and white.

When choosing a monitor from which company it is better to buy, it is recommended to evaluate the needs of the operating room, as well as the overall dimensions of the place where it will be installed.
Due to the fact that this product has a large number of characteristics, when choosing a specific model, it is worth focusing not only on the wishes of the doctor who will use it, but also get advice from a technical specialist on its compatibility with existing endoscopic equipment in order to avoid not purchasing a machine that cannot be used, or that would cost half the cost to be compatible.
The most important parameters to be evaluated are: viewing angles, contrast, brightness, resolution, availability of additional features. Many surgeons recommend buying models that are capable of broadcasting several images at once in parallel, or displaying a “picture in picture”.You should not buy products from budget brands, since they are inferior to their competitors not only in terms of functionality, but also in terms of build quality, materials used, as a result of which it quickly fails and requires repair (in most cases, expensive) or the purchase of a new device.
Unfortunately, the products of many well-known brands are not available for free sale in Russia, and you have to deal with the search for such video monitors on your own, finding contact with foreign companies. We hope that our article will help you make the right choice!
