A surgical auxiliary lighting device

Abstract

The present invention belongs to the technical field of auxiliary lighting equipment, and in particular, is an auxiliary lighting equipment for surgical operations. In view of the fact that many shadowless lamps in existing surgical operations are generally fixed in angle, and it is difficult for light to enter places, the illumination range of the light source cannot be controlled when the light source is operated far or near, which easily leads to the light source being too strong at close range, causing damage to the eyes of the user. The following scheme is now proposed, which includes: a mounting seat; a support column, fixedly mounted on the mounting seat, a block fixedly mounted on the top of the support column, a mounting tube movably connected to the support column, and a fixing box fixedly mounted on the top of the mounting tube. The present invention has a simple structure, and can facilitate the automatic adjustment of the lighting range while adjusting the lighting height, so that the lighting range can adapt to people's use according to the height, and can also keep the lighting position unchanged when the light source is moved and rotated, so as to facilitate people's use.
