How to Choose a Shadowless Surgical OT Light?

Surgical shadowless OT lights are used for surgical site lighting, providing high brightness, excellent color temperature, shadowless illumination, and good focusing for human tissues and organs in incisions and body cavities.

Selection methods for shadowless surgical OT light

Check if the surgical shadowless OT light has a good cold light source

Due to the sensitivity of infections to temperature, the head temperature of surgeons should not rise more than 2 Celsius degrees. The same temperature has a great impact on the lifespan of electronic components, circuits, and bulbs. Statistical data shows that the lifespan of most shadowless OT lights is related to temperature.

Depend on the number of connections and the stability and flexibility of the lamp arm

The ideal choice for illuminating a China OT table evenly is a shadowless surgical lamp with multiple connections. It is preferable that each connection can rotate more than 300 degrees, or up to 360 degrees, to ensure the light is dispersed to all areas of the surgical table.

Observe its irradiation distance and depth

Generally, the larger the lamp board or the more shadowless OT light heads, the better the irradiation depth, and the more suitable for deep surgery. Complex surgery usually requires a large surgical lamp with more than 40 lamp sockets to achieve good irradiation effects.

Check the intensity and color temperature of light

Phototherapy equipment manufacturers can offer high-quality shadowless OT lights that can produce light with an intensity of up to 16,000 lux. For optimal performance, an adjustable color temperature is advisable in choosing a shadowless OT light.

Check if the shadowless surgical lamp has a beautiful appearance

This petal-shaped design not only gives a relaxing and pleasant appearance, but also has a significant effect in reducing lamp turbulence and resistance.

Pay attention to whether the light spot is even

The materials used, whether it is a heat sink, and a high-definition camera system are all factors we must consider.

Precautions for shadowless surgery OT light

  • The temperature around the shadowless OT light during surgery should be maintained between 10°C and 40°C.

  • Halogen bulbs are very sensitive to human fats. The bulb should never come into contact with human oils, as this can cause "hot spots" and lead to bulb failure.

  • The shadowless OT light should be wiped on both sides with a clean, dry cloth 30 minutes before and after surgery to ensure that it is free of dust, debris, and blood stains, and corrosive disinfectants should be avoided.

  • When adjusting the position of the surgical lamp, care should be taken to avoid collisions with the ceiling, display screens, or IV poles, and the height should be suitable and in accordance with sterile operating procedures. After surgery, the shadowless OT light should be fixed in the center of the surgical bed and kept balanced.

  • The relative humidity in the operating room should not exceed 75%, as humidity above 75% can damage the shadowless OT light.

  • When adjusting the shadowless OT light, its intensity should be gradually increased from weak to strong. Directly turning it to the highest setting should be avoided, as this can damage the bulb. At the end of the surgery, the lamp should be set to the lowest intensity before turning off the power switch or control panel.

  • The lamp handle should be removed and cleaned after use, and contaminated handles should be promptly removed.

  • A thorough cleaning of the shadowless surgery lamp, including the ceiling, connecting rods, and movable arms, should be done once a week, and the joints should be checked for any abnormalities and promptly reported.
