Description

Technical Field

[0001] This utility model relates to the field of medical equipment technology, specifically to an adjustable-angle surgical shadowless lamp. Background Technology

[0002] During medical surgery, a clear view of the surgical area directly determines the accuracy and safety of the operation. As a core auxiliary device, the surgical shadowless lamp's core function is to eliminate shadows through the synergistic effect of multiple light sources, providing uniform illumination for medical staff.

[0003] Traditional surgical shadowless lamps mostly use simple single-arm or double-arm rotating structures, which can only achieve a small range of angle adjustments. For scenarios that require frequent changes in surgical sites, it is difficult to quickly and accurately cover the target area with light, requiring repeated movement of the lamp base, which interferes with the surgical procedure. In addition, the light source of traditional surgical shadowless lamps is mostly a fixed overall layout, which can easily produce subtle shadows due to improper local light source angles, affecting the operation judgment.
