The adjustable shadowless lamp comprises a rolling wheel mechanism, a rotating circular hole is formed in the center of the left end of a base, a rotating shaft is sleeved with the rotating circular hole, the right end of the rotating shaft is fixedly connected with a rotating disc, a limiting clamping column is fixedly connected to the top end of the left side of a rotating handle, a driving gear is in gear fit with a rack, limiting blocksare arranged at the left end and the right end of the rack, the top end of the rack is fixedly connected with a connecting column, the connecting column is connected with a rotating column, a rotatingsupport is arranged at the top end of the rotating column, a clamping gear sleeves the middle of a clamping shaft, a movable shaft penetrates through the position, which is coplanar with the axis ofthe clamping shaft, of the right side of the upper end of the rotating support, the middle of the movable shaft is sleeved with a connecting tooth block, a clamping gear is in gear fit with the connecting tooth block, the side end of the connecting tooth block is fixedly connected with a lamp support, and a shadowless lamp body is installed on the lamp support. According to the shadowless lamp, moving and fixing can be convenient, meanwhile, fixed-point placement in any direction within a reachable range can be achieved, and moreover, the stability is good.

Description

technical field [0001] The invention relates to the field of ophthalmic medical instruments, in particular to an adjustable shadowless lamp for an ophthalmic operating room. Background technique [0002] The so-called 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, because the operator's head, hands and instruments may cause damage to the surgical site Interfering with shadows, so the surgical shadowless lamp should be designed to eliminate shadows as much as possible and minimize color distortion. In addition, the shadowless lamp must be able to work continuously for a long time without emitting excessive heat, because overheating will make the operation Discomfort and dry out tissue in the surgical field. However, the existing surgical shadowless lamps have shortcomings in design and structure, and provide less help to users. Traditional surgical shadowless la...
