What is the function of operating light’s internal camera?

Now operating light is more and more used in operating room, playing an important role. Some operating light equips with internal camera system, which is put in the central handle of operating light, including 1 handle (tubular shell, internal gear in one end) and 1 fixed plate (outer ring fixed, inner ring rotation, put in the handle).

There are circuit board and lampholder lifting mechanism in outer ring; camera put in the handle and connect with the inner ring of fixed plate. Camera and handle rotation mechanism are separated by fixed plate, using handle internal gear and belt drive, handle rotation and the lampholder lifting mechanism are linked, therefore, the camera will not be affected when the handle is adjusted
