What is shadowless surgical light?

Shadowless surgical lights are used to illuminate the surgical site so that small, low-contrast objects at different depths in the incision and body cavity can be observed. Since the operator’s head, hands and instruments may produce disturbing shadows in the operating area, the design of shade-free lamp should eliminate shadows as much as possible to reduce color distortion to a low level. In addition, shadowless lights must be able to work continuously for long periods of time without emitting excessive heat, as overheating can make the operator uncomfortable and dry out the tissue in the surgical area.

Does shadowless surgical light not have a shadow?

In fact, shadowless light is not “shadowless”, it is only to reduce the shadow, so that the shadow is not obvious. Shadows are caused by light falling on objects.

The cantilever is usually attached to a fixed combiner and can be rotated around it. The shadowless light is positioned flexibly through disinfection handle or disinfection hoop (arc track) and has automatic brake and stop functions to control its positioning, thus maintaining appropriate space above and around the surgical site. Shadowless light fixtures can be placed on fixed points in the ceiling or wall or on ceiling rails.
