Abstract
Description
Technical Field
[0001] This utility model belongs to the field of shadowless lamp technology, and in particular relates to a vertical surgical shadowless lamp. Background Technology
[0002] Surgical shadowless lamps are devices used for illumination during surgical procedures. The shadowless illumination area they create allows surgeons to observe incisions, affected areas, and other sites in detail. They enable optimal observation of small, low-contrast objects at different depths within the incision and body cavity, and precise differentiation of tissue outlines, colors, and the movement of surgical instruments. Furthermore, the surgeon's head, hands, and instruments can all create interfering shadows on the surgical site. Therefore, surgical shadowless lamps should be designed to minimize shadows and reduce color distortion to the lowest possible level, thereby improving surgical precision and accelerating the surgical process.
[0003] Existing surgical shadowless lamps are divided into standing and hanging types. Standing shadowless lamps can be moved and are more flexible in use, but because the support rod of the shadowless lamp is long, it occupies a lot of space. When not in use or when storing, it affects the space occupied. Some foldable or retractable shadowless lamps are more troublesome to unfold when in use, which affects the efficiency of use.
[0004] Therefore, we propose a vertical surgical shadowless lamp to solve the above problems. Utility Model Content
[0005] The purpose of this invention is to solve the problem in the existing technology that the unfolding and storage of the lamp is cumbersome and affects the efficiency of use, and to propose a vertical surgical shadowless lamp.

[0008] The first connecting rod is provided with a first one-way ratchet assembly at the hinge point between it and the column, and the second connecting rod is provided with a second one-way ratchet assembly at the hinge point between it and the column. The top surface of the base is fixedly connected to a first placement seat that cooperates with the first connecting rod, and the top of the column is fixedly connected to a second placement seat that cooperates with the lamp and the second connecting rod.
[0009] Preferably, the first one-way ratchet assembly includes a first ratchet fixedly mounted on the column, and the first connecting rod is hinged to the column and coaxially arranged with the first ratchet. The side wall of the first connecting rod is rotatably connected to a first pawl that engages with the first ratchet.
[0010] Preferably, a first spring is fixedly connected to the side wall of the first connecting rod to drive the first pawl to approach the first ratchet.
[0011] Preferably, a first knob is rotatably connected to the outer wall of the first connecting rod, and the first knob is coaxially connected to the first pawl.
[0012] Preferably, a first magnetic attraction assembly is fixedly provided between the first placement seat and the first connecting rod to attract each other, and a second magnetic attraction assembly is fixedly provided between the second placement seat and the second connecting rod to attract each other.
[0013] Preferably, a limiting rod is fixedly connected to the side wall of the column, and the side wall of the first connecting rod is provided with a limiting groove for the limiting rod to pass through and move.
[0014] Preferably, the limiting groove is arc-shaped and less than 180°.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.
[0022] Reference Figure 1-3 A vertical surgical shadowless lamp includes a base 1, a column 2 fixedly connected to the top surface of the base 1, a first connecting rod 3 hinged to the top of the column 2, a second connecting rod 4 connected to the other end of the first connecting rod 3, and a lamp 5 rotatably mounted on the top of the second connecting rod 4.
[0023] A first one-way ratchet assembly is provided at the hinge point between the first link 3 and the column 2, and a second one-way ratchet assembly is provided at the hinge point between the second link 4 and the column 2. A first placement seat 6 that cooperates with the first link 3 is fixedly connected to the top surface of the base 1, and a second placement seat 7 that cooperates with the lamp 5 and the second link 4 is fixedly connected to the top of the column 2.
[0024] Reference Figure 1-3 When the vertical surgical shadowless lamp is stored, the end of the first connecting rod 3 is attached to the first placement seat 6, the end of the second connecting rod 4 is attached to the second placement seat 7, and the bottom of the lamp 5 is attached to the second placement seat 7, so as to achieve stable placement of the lamp 5, the first connecting rod 3 and the second connecting rod 4.
[0025] When in use, first rotate the first link 3. After rotating the first link 3 to the appropriate position, release it. The first one-way ratchet assembly will then fix the first link 3. After that, rotate the second link 4. After rotating the second link 4 to the appropriate position, release it. The second one-way ratchet assembly will then fix the second link 4. After that, the lamp 5 can be lit.
[0026] Reference Figure 4 The first one-way ratchet assembly includes a first ratchet 8 fixedly mounted on the column 2, and the first link 3 is hinged to the column 2 and coaxially arranged with the first ratchet 8. The side wall of the first link 3 is rotatably connected to a first pawl 9 that cooperates with the first ratchet 8.
[0027] A first spring 10 is fixedly connected to the side wall of the first link 3 to drive the first pawl 9 to approach the first ratchet 8. The first spring 10 ensures that the first pawl 9 always fits against the first ratchet 8 when there is no external interference.
[0028] Reference Figure 2-4 The outer wall of the first link 3 is rotatably connected to a first knob 11, and the first knob 11 is coaxially connected to the first pawl 9. The first knob 11 is used to rotate the first pawl 9, thereby controlling the separation between the first pawl 9 and the first ratchet 8, thus realizing the reverse rotation and storage of the first link 3.
[0029] Conversely, the second one-way ratchet assembly includes a second ratchet, a second pawl, a second spring, and a second knob. Since the second one-way ratchet assembly operates on the same principle as the first one-way ratchet assembly, it will not be described in detail and will not be marked in the figure.
[0030] A first magnetic attraction component 12 is fixedly provided between the first placement seat 6 and the first connecting rod 3, and a second magnetic attraction component 13 is fixedly provided between the second placement seat 7 and the second connecting rod 4, so that when the first connecting rod 3 and the second connecting rod 4 are stored, the mutual attraction of the magnets avoids the problem of accidental rotation of the first connecting rod 3 and the second connecting rod 4 caused by external forces or vibrations, thus improving the stability of placement.
[0031] Reference Figure 2-4 A limiting rod 14 is fixedly connected to the side wall of the column 2. A limiting groove 15 is provided on the side wall of the first connecting rod 3 for the limiting rod 14 to pass through and move. The limiting rod 14 cooperates with the limiting groove 15 to limit the rotation angle of the first connecting rod 3. Correspondingly, the hinge joint between the second connecting rod 4 and the first connecting rod 3 also has the same structure to limit the rotation angle of the second connecting rod 4.
[0032] The limiting groove 15 is arc-shaped and less than 180°, thereby limiting the first connecting rod 3 to always be located on one side of the column 2. This ensures the normal operation of the first one-way ratchet assembly while preventing the center of gravity from shifting too much and affecting the stability of use.
[0033] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
