Description

Technical Field

[0001] The invention relates to the technical field of medical equipment, and in particular to a surgical shadowless lamp. Background Art

[0002] The surgical shadowless lamp is used to illuminate the surgical site. It can optimally observe small, low-contrast objects at different depths in the incision and body cavity. It arranges the lamps with high luminous intensity in a circle on the lamp panel to form a large-area light source, which can irradiate light onto the operating table from different angles, ensuring that the surgical field has sufficient brightness without producing an obvious umbra.

[0003] After searching, the patent publication number CN216521262U discloses a "multi-angle shadowless lamp for operating room", which includes a base plate for installation above the operating table and a first lamp holder installed below the base plate. Several connecting plates are arranged at intervals along the circumference on the outer end surface of the base plate. One end of each connecting plate is connected to the base plate, and a mounting seat is installed below the other end through a connecting rod. The upper end of a connecting shaft is embedded in the mounting seat and rotatably installed on the mounting seat through a rotating shaft. The lower end of the connecting shaft is installed with a second lamp holder. This device not only expands the coverage of the light source, but also allows light to irradiate the operating table from multiple angles.

[0004] In the prior art, a shadowless lamp generally consists of a single or multiple lamp heads, which are fixed on a cantilever and can move vertically or circularly. The shadows produced when the main body of the shadowless lamp is irradiated can be supplemented by an auxiliary small shadowless lamp to reduce the umbra. However, during the operation, due to the change of the operating position, the main body of the shadowless lamp needs to be repeatedly moved so that it can stably illuminate the operating position. The small shadowless lamp is generally fixedly installed on the main shadowless lamp, which makes it inconvenient for personnel to operate. In addition, the small shadowless lamp cannot be moved, which makes it unable to adapt to the multi-directional supplementary lighting needs, resulting in poor irradiation effect.
