Today, I would like to introduce to you, how to choose a surgical shadowless lamp?

Surgical shadowless lamps are mainly divided into 3 types: mobile, hanging and wall-mounted. The lamp head of the shadowless lamp is mainly 500/700 lamp panel, there are single head 500/700, and there are double head 700/500 sub-mother lamps.

Depending on the department, there are also different choices for shadowless lamps:

The mobile/hanging 500 lamp head is mainly used for: ophthalmology, ENT, minimally invasive, etc.

Hanging 700 lamp holder is mainly used for: obstetrics, beauty, general surgery, etc.

Hanging 700/500 lamp holders are mainly used for: orthopedics, extracerebral, thoracic, etc.

Traditional halogen lamps are gradually replaced by LED light sources due to their short service life, high heat dissipation, and unstable lighting quality. Therefore, choosing a suitable LED operating lamp is a concern of our medical staff. A good surgical light must be judged on the basis of a large amount of data. Different surgeries and surgical methods have different requirements and look at surgical lights.

How to choose the right surgical shadowless lamp? I think the following aspects can generally be considered: Hospitals can choose LED operating lights that suit their surgical needs according to different locations in the operating room. An ideal LED operating light should have the following conditions:

1. Irradiation distance: The irradiation distance of the surgical shadowless lamp is generally about 70-140 cm or 60-130 cm (that is, the surgical shadowless lamp has a better shadowless effect within this distance).
2. Size and quantity of single headlights: The larger the lamp panel of the surgical shadowless lamp (single headlight) or the more heads, the better the illumination depth, and the more suitable for relatively deep surgery.
3. Appropriate illuminance: The illuminance that the surgical shadowless lamp can provide to the operating table is 20000-100000LUX, and it is better to have a multi-level dimming control function, too bright will affect the doctor's vision; try to avoid the light beam on the surgical instrument and produce glare, glare It will also affect the doctor's vision and vision, and it is easy to cause eye fatigue, which is not conducive to the doctor's operation.
4. Color temperature: The color temperature of the surgical shadowless lamp is about 4500K, and the color rendering index is not lower than 95, so that the surgical shadowless lamp illumination does not change the skin color of the patient and the color of the wound tissue.
5. Beam diameter: The beam diameter of surgical shadowless lamp lighting ranges from 10-25 cm, and the diameter of the beam can be adjusted by adjusting the handle
6. Temperature rise: Increasing the illuminance will inevitably cause the temperature of the lamp body and the beam to rise, which will affect the temperature of the doctor's head and tissue at the surgical site, thereby affecting the efficiency and quality of surgery; it is precisely because of the sensitivity of temperature to patient infection Therefore, it is required that the temperature rise of the shadowless lamp should be lower than 2 degrees per hour, and the temperature rise of the operating room should be controlled within 10 degrees Celsius. Similarly, the increase in temperature has a great impact on the life of the electronic devices, circuits, light sources, etc. in the surgical shadowless lamps. Most of the failures and damages of the surgical shadowless lamps are related to temperature.
7. Infrared and glare: The surgical shadowless lamp minimizes and eliminates the infrared and glare components in the shadowless lamp through the lens and filter design.
8. Easy to operate: The surgical shadowless lamp should be able to continuously change the position and direction during the operation, and the operation must be simple, flexible, light, fast and effective in braking. The central part of the lamp body should be equipped with a sterilizable operating handle, and the lamp should be able to flexibly adjust horizontally and vertically and rotate 360 ​​degrees.
9. No interference: For surgical shadowless lamps with camera function or image transmission function and wireless intelligent remote control, the camera and lamps should be integrated and arranged without interfering with each other.
