There are four key functions of the surgical shadowless lamp: high shadowlessness, convenient actual operation, low temperature, economy and safety factor. These 4 functions are indispensable functions of the machine and equipment during operation. The shadowlessness is a relatively critical function in the whole process of surgical treatment. If ordinary lighting equipment is used, the lights will not only heat up, but also The shadowlessness is relatively low, so it cannot be compared with surgical shadowless lamps.

1. Surgical treatment has a high degree of shadowlessness

Shadowlessness is the key form and performance parameter of the shadowless lamp. All shadows produced in the surgical treatment field will affect the doctor’s observation, discrimination and surgical treatment. A well-maintained shadowless lamp should not only provide sufficient light intensity, but also have a high Shadowlessness, to ensure that the surface and deep tissues of the surgical treatment field have standardized luminosity. For testing for shadowlessness, use a 50X75mm black cylinder, 1 meter above the light source, and a photometer at the bottom of the cylinder. The measured light and shadow ratio is not Less than 10%. In fact, the product used is to equip several or a dozen light bulbs in a balanced order in a ring with a diameter of 50-100 cm. The light bulb uses a special bulb and reflector, and the light beam is different. The position of the light is reflected by the filter and meets at one point to provide a balanced, balanced and shadowless bright beam.

2. The actual operation is convenient

The surgical shadowless lamp should be able to continuously change its position and direction during the operation. The actual operation must be simple, flexible, light, fast and effective. The central body of the lamp should be equipped with a sterilizable control handle. Advanced products should also be equipped with a light guide Fiber deep cold light lamps, color television photography equipment and ventilation equipment.

3. Low temperature

The increase of the light intensity will inevitably lead to the increase of the temperature of the lamp body and the light beam, which will affect the temperature of the doctor’s head and body parts during the operation, and then affect the efficiency and quality of the operation. For this reason, the temperature rise in the operating room It is required to be controlled within 10°C. The key method adopted by Heilongjiang surgical shadowless lamp is to pass the visible light generated by the light source through a reflector that can filter out 70% of infrared rays. Most of the remaining infrared rays are isolated and filtered by the glass cover. The light beam is called cold light.

4.Economy and safety factor

The key to economy is that the light source has high luminous efficiency, low power consumption and long service life.

The above is the relevant professional knowledge about the essential functions of the surgical shadowless lamp. You can fully understand it. I hope this short article can help you. On the other hand, we recommend that you master the relevant professional knowledge of machinery and equipment. It can help you reduce application misunderstandings in the mid to late application process.
