Description

Technical Field

[0001] The utility model belongs to the technical field of shadowless lamps, and in particular relates to a shadowless lamp panel for surgery. Background Art

[0002] The surgical shadowless lamp is used to illuminate the surgical site to best observe small, low-contrast objects at different depths in the incision and body cavity. Since the surgeon's head, hands and instruments may cause interfering shadows on the surgical site, the surgical shadowless lamp should be designed to eliminate shadows as much as possible and minimize color distortion.

[0003] The surgical shadowless lamp in the prior art usually has the function of adjusting the illumination angle, but because its rotating structure is usually a plastic damping structure, it will slip after long-term use, resulting in the lamp panel being unable to be effectively limited and fixed, and usually during the operation, blood may splash onto the surface of the shadowless lamp. Therefore, the shadowless lamp needs to be disinfected and cleaned after the operation. The Chinese patent with announcement number: CN216952731U (application number: CN202123021323.3) discloses an LED surgical shadowless lamp, including a shadowless lamp mounting frame, a shadowless lamp body is fixedly arranged in the middle of the inner side of the shadowless lamp mounting frame, and a plurality of lamp bodies are evenly fixedly arranged on the outer surface of the shadowless lamp body. A sealing mechanism is arranged on the outer surface of the lamp body, and the sealing mechanism includes a lampshade, a telescopic rod, a clamping block, a spring, and a clamping groove. A lampshade is movably engaged on the outer surface of the lamp body. Since a lampshade is installed on the surface of each lamp body, the surface of the lamp panel is uneven, which makes it easy to accumulate dirt and inconvenience during disinfection and cleaning.
