Description

Technical Field

[0001] The utility model relates to the technical field of medical equipment, and more specifically, to a shadowless lamp for lighting in an operating room without dead angles. Background Art

[0002] Surgical shadowless lamps are used to illuminate the surgical site to optimally observe small, low-contrast objects at different depths in the incision and body cavity. Since the surgeon's head, hands, and instruments may cast interfering shadows on the surgical site, 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 surgeon uncomfortable and will also dry out the tissues in the surgical area.

[0003] During the operation, the surgeon often uses a corresponding shadowless lamp to reduce the impact of shadows on the surgeon during the operation. In actual use, although the existing surgical shadowless lamps have basic lighting functions, they are unable to provide lighting without blind spots due to the different surgical incision positions, which brings inconvenience to the surgeon during use, so improvements are needed.

[0029] A cross bar 3, the left end of which is fixedly mounted on the outer surface of the rotating rod 2;

[0030] A rotating mechanism, which is arranged at the bottom of the mounting block 1;

[0031] Among them, the rotating mechanism includes a driving motor 4, which is fixedly installed on the left side of the bottom of the mounting block 1. The other end of the output shaft of the driving motor 4 is fixedly sleeved with a rotating shaft 5, and the other end of the rotating shaft 5 is fixedly sleeved with a No. 1 gear 6. The outer surface of the No. 1 gear 6 is meshed and connected with a No. 2 gear 7. The interior of the No. 2 gear 7 is fixedly sleeved with the outer surface of the rotating rod 2. The rotation of the No. 1 gear 6 will cause the No. 2 gear 7 to drive the rotating rod 2 to rotate.

[0032] When the driving motor 4 starts to run, the rotating shaft 5 drives the first gear 6 to rotate, and the second gear 7 drives the rotating rod 2 to rotate together.

[0033] As a preferred technical solution of the utility model, the other end of the cross bar 3 is hinged with a connecting rod 8, the other end of the connecting rod 8 is hinged with a semicircular block 9, the internal movable sleeve of the bottom of the semicircular block 9 is connected with a first rotating rod 10, and the outer surface of the first rotating rod 10 is fixedly installed with a No. 1 arc plate 11, and the other end of the No. 1 arc plate 11 is fixedly installed with a fixed block 12.

[0034] When the first arc plate 11 is pulled, the first rotating rod 10 will rotate.

[0035] As a preferred technical solution of the utility model, a second rotating rod 13 is movably sleeved inside the left side of the fixed block 12, a second arc plate 14 is fixedly mounted on the outer surface of the second rotating rod 13, and a mounting frame 15 is fixedly mounted on the other end of the second arc plate 14.

[0036] When the mounting bracket 15 is pulled, the second arc plate 14 will drive the second rotating rod 13 to rotate.

[0037] As a preferred technical solution of the present utility model, a vertical groove 16 and a rectangular groove 17 are respectively provided at the bottom of the left and right sides of the inner cavity of the mounting frame 15, and a moving plate 18 is movably connected to the inner surface of the mounting frame 15. A limiting block 21 is fixedly installed on the left side of the moving plate 18, and the outer surface of the limiting block 21 is movably connected to the inside of the vertical groove 16. A second spring 26 is fixedly connected to the top of the limiting block 21, and the other end of the second spring 26 is fixedly connected to the top of the vertical groove 16.

[0038] When the limiting block 21 moves, the moving plate 18 is driven to move vertically up and down under the limiting action of the vertical slot 16 .

[0039] As a preferred technical solution of the utility model, a first spring 22 is fixedly installed inside the right side of the moving plate 18, and a rectangular block 23 is fixedly installed on the other end of the first spring 22. The outer surface of the rectangular block 23 is movably socketed with the inner part of the moving plate 18, and the outer surface of the rectangular block 23 is movably connected with the inner part of the rectangular groove 17.

[0040] When the moving plate 18 moves to the position of the rectangular slot 17 , the rectangular block 23 can pass through the rectangular slot 17 due to the elastic force of the first spring 22 , thereby achieving a fixing effect on the moving plate 18 .

[0041] As a preferred technical solution of the utility model, both the front and rear sides of the moving plate 18 are hinged with inclined rods 19 , and the other end of the inclined rods 19 is hinged with a clamping plate 20 .

[0042] When the moving plate 18 moves, the inclined rod 19 is driven to move, so that the two clamping plates 20 move toward or away from each other.

[0043] As a preferred technical solution of the present utility model, mounting plates 25 are fixedly installed on the front and rear sides of the middle part of the inner cavity of the mounting frame 15, a limiting groove 24 is provided on the top of the mounting plate 25, the top of the mounting plate 25 is movably connected to the bottom of the clamping plate 20, and the inner surface of the limiting groove 24 is movably connected to the outer surface of the clamping plate 20.

[0044] When the clamping plate 20 moves, it will move horizontally toward or away from each other under the limiting effect of the limiting groove 24.

[0045] The working principle and use process of this utility model:

[0046] Firstly, after turning on the shadowless lamp, the lighting angle and direction can be adjusted by rotating the second rotary rod 13, the first rotary rod 10 and the connecting rod 8. When the initial position of the device does not meet the lighting requirements, starting the driving motor 4 will cause the rotating shaft 5 to drive the first gear 6 to rotate, and the second gear 7 will drive the rotating rod 2 to start rotating, thereby causing the connecting rod 8, the first arc plate 11, the second arc plate 14 and the mounting bracket 15 to rotate together, ultimately achieving the function of lighting without blind spots and improving the lighting effect of the device.

[0047] When the shadowless lamp is damaged and needs to be repaired or replaced, pressing the rectangular block 23 will compress the first spring 22. When the rectangular block 23 is out of the rectangular groove 17, the fixing effect on the moving plate 18 will be released. At this time, due to the elastic force of the second spring 26, the limit block 21 will drive the moving plate 18 to move vertically upward under the limiting effect of the vertical groove 16, and drive the diagonal rod 19 to start moving. At this time, due to the limiting effect of the limit groove 24, the two clamping plates 20 will move horizontally away from each other, thereby releasing the fixing effect on the base of the shadowless lamp, which facilitates the disassembly and assembly operations of the maintenance personnel.

[0048] It should be noted that, in this article, relational terms such as first and second, etc. are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Moreover, the terms "include", "comprise" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device.
