[0051] The exemplary embodiments of the present invention will be described in more detail below with reference to the accompanying drawings. Although the exemplary embodiments of the present invention are shown in the accompanying drawings, it should be understood that the present invention can be implemented in various forms and should not be limited by the embodiments described herein. On the contrary, these embodiments are provided to enable a more thorough understanding of the present invention and to fully convey the scope of the present invention to those skilled in the art.

[0052] like Figures 1 to 4 As shown, an embodiment of the utility model provides a multi-angle shadowless lamp, comprising: a mounting plate 1, a shadowless lamp 12; a first motor 2, arranged on the mounting plate 1; a first mounting block 3, arranged at the output end of the first motor 2; an adjustment component, arranged on the first mounting block 3, and connected to the shadowless lamp 12 to adjust the position and angle of the shadowless lamp 12; a shading component, arranged on the shadowless lamp 12 to block the light of the shadowless lamp 12.

[0053] In the embodiment of the utility model, the setting adjustment component can drive the shadowless lamp 12 to move arbitrarily on the operating table, so as to be adjusted to a suitable position and angle for surgical operations; the setting shading component can block the light when a wide range of light is not needed, thereby reducing the possibility of glare to the operator during a long operation; wherein, starting the first motor 2 can drive the first mounting block 3 to rotate, and the first motor 2 is set as a stepping motor; at the same time, the device is installed on the ceiling as a whole, and when using the shadowless lamp 12, it will not hinder the medical staff from moving around the operating table, which is more convenient. During installation, it is only necessary to bolt the bolts through the mounting holes 23 and hit them on the ceiling.

[0054] like Figure 1 As shown, the adjustment component includes: a telescopic component, which is arranged on the first mounting block 3; a second mounting block 6, which is arranged on the telescopic component; an electric telescopic rod 7, which is arranged on the second mounting block 6; a third mounting block 8, which is arranged at the output end of the electric telescopic rod 7; and an angle adjustment component, which is connected to the third mounting block 8.

[0055] In the embodiment of the utility model, the telescopic assembly can be extended and retracted to drive the second mounting block 6 to move horizontally, and the second mounting block 6 can drive the electric telescopic rod 7 to move horizontally. At the same time, by controlling the electric telescopic rod 7, the third mounting block 8 can be driven to move up and down, thereby realizing the vertical adjustment of the shadowless lamp 12.

[0056] like Figure 4As shown, the telescopic assembly includes: a sleeve 4, which is fixedly connected to one end of the first mounting block 3; a first spring 19, which is arranged in the sleeve 4; a first connecting rod 5, one end of which is fixedly connected to the first spring 19, and the other end of which is fixedly connected to the second mounting block 6, wherein the sleeve 4 is slidably mounted on the first connecting rod 5; a groove is provided on the first connecting rod 5; a second spring 21 is embedded in the groove; a limiting hole 20 is provided on the sleeve 4; and a push rod 22, one end of which passes through the limiting hole 20 and is connected to the second spring 21.

[0057] In the embodiment of the utility model, when the horizontal position of the shadowless lamp 12 needs to be changed during surgery, the staff needs to manually press the push rod 22 with one hand and pull the first connecting rod 5 with the other hand, so that the push rod 22 moves downward until it is in the same straight line with the surface of the sleeve 4. Since the upper end of the push rod 22 is arranged in an arc shape, at this time, the push rod 22 is moved downward by the pulling force of the staff, so that the push rod 22 is completely entered into the groove of the first connecting rod 5. At this time, the first connecting rod 5 is driven to slide in the specified direction in the sleeve 4 through the pulling force of the staff, so as to be adjusted to the specified position. When reaching the designated position, the elastic force of the second spring 21 will push the push rod 22 to the corresponding limiting hole 20, so that the sleeve 4 and the first connecting rod 5 are clamped together and cannot move, thereby avoiding the shadowless lamp 12 from moving when using it, thereby affecting the operation; wherein, there are a plurality of limiting holes 20, and the plurality of limiting holes 20 are arranged on the same straight line. Through the arrangement of the plurality of limiting holes 20, the limiting holes 20 can be adjusted step by step during adjustment, thereby avoiding a large displacement of objects during adjustment by the staff.

[0058] like Figure 3 As shown, the shading assembly includes: a first fixed rod 13, one end of which is connected to the top of the shadowless lamp 12; a fixed disk 14, which is connected to the other end of the first fixed rod 13; a driving assembly, which is arranged on the fixed disk 14; and a shielding assembly, which is arranged on the driving assembly.

[0059] In the embodiment of the utility model, the shielding assembly is driven to move up and down by the driving assembly.

[0060] like Figure 1 As shown, the angle adjustment assembly includes: a second motor 9, installed on one side of the third mounting block 8; a second connecting rod 11, one end of which is passed through the third mounting block 8 and fixedly connected to the output end of the second motor 9, and the other end of which is fixedly connected to the shadowless lamp 12.

[0061] In an embodiment of the utility model, the second motor 9 is started, and the output end of the second motor 9 is fixedly connected to the second connecting rod 11 through the third mounting block 8, thereby driving the second connecting rod 11 to rotate. The second connecting rod 11 is fixedly connected to the shadowless lamp 12, thereby driving the shadowless lamp 12 to rotate, thereby realizing the adjustment of the angle of the shadowless lamp 12.

[0062] like Figures 1 to 4 As shown, the driving assembly includes: a third motor 15, which is arranged on the fixed disk 14; a threaded rod 16, one end of which is rotatably connected to the bottom end of the fixed disk 14, and the other end of which is rotatably connected to the shadowless lamp 12; and a threaded sleeve 17, which is sleeved on the threaded rod 16.

[0063] like Figure 1 As shown, the shielding assembly includes: a second fixing rod 18, one end of which is connected to the outer wall of the threaded sleeve 17; an arc-shaped baffle 10, the inner wall of which is connected to the other end of the second fixing rod 18 and is slidably connected to the shadowless lamp 12.

[0064] In the embodiment of the utility model, the third motor 15 is started to drive the threaded rod 16 to rotate, the threaded rod 16 drives the threaded sleeve 17 to move up and down, the threaded sleeve 17 drives the second fixed rod 18 to move up and down, thereby driving the arc baffle 10 to move up and down; the arc baffle 10 is slidably connected to the shadowless lamp 12, and at the same time limits the threaded sleeve 17 to prevent the threaded sleeve 17 from rotating with the threaded rod 16 when the threaded rod 16 rotates; when using the device, the third motor 15 can be started by the nursing staff at a fixed time, so that the arc baffle 10 moves downward, and the arc baffle 1 0 will block the light that the shadowless lamp 12 radiates to the surroundings, so that the shadowless lamp 12 has no effect on the directly irradiated surgical site, but weakens the light refracted to the surroundings, thereby reducing the impact of light on the operator without affecting the operation; wherein, the intensity of the light shielding is changed by adjusting the degree of downward movement of the arc-shaped baffle 10; at the same time, since the shadowless lamp 12 needs to be turned on for a long time during the operation, the heat dissipation plate and the heat dissipation fan can effectively dissipate the heat of the shadowless lamp 12 through the setting of the heat dissipation plate and the heat dissipation fan, thereby avoiding excessive heat, which may cause damage to the shadowless lamp 12 and affect the operation.

[0065] Working principle: when adjusting the shadowless lamp 12, start the first motor 2 to drive the sleeve 4 and the first connecting rod 5 to rotate horizontally, and then manually press the push rod 22 to adjust the first connecting rod 5 to slide to the specified position in the sleeve 4. The push rod 22 is pushed out under the action of the second spring 21 and is clamped on the specified limit hole 20, thereby fixing the sleeve 4 and the first connecting rod 5. At this time, the horizontal position of the shadowless lamp 12 is determined, and then the electric telescopic rod 7 is started to adjust the vertical position of the shadowless lamp 12; finally, start the second motor 9 to drive the second connecting rod 11 to rotate, thereby driving the shadowless lamp 12 to rotate, thereby adjusting the angle of the shadowless lamp 12; when shading is required, start the third motor 15 to drive the threaded rod 16 to rotate, and the threaded rod 16 drives the threaded sleeve 17 to move downward. The threaded sleeve 17 is fixedly connected to the arc baffle 10 through the second fixing rod 18, thereby driving the arc baffle 10 to move downward, thereby weakening the light refracted by the shadowless lamp 12 to the surroundings, reducing the influence of light on the operator, thereby improving the operation efficiency.

[0066] The above is a preferred embodiment of the present invention. It should be pointed out that, for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principles of the present invention. These improvements and modifications should also be regarded as the protection scope of the present invention.
