Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of laboratory auxiliary tools, in particular to a slide marking device. Background Art
[0002] During the chromosome karyotype analysis, when encountering complex abnormal karyotypes, metaphase FISH is required. The specific operation requires first finding the mitotic phase under the microscope, then narrowing the light source to a small point, and using a marker to mark the top, bottom, left, and right points not far from the light source on the slide with the naked eye. Then take out the slide and use a marker to mark the centers of the four points on the back of the slide. At this time, use a microscope to observe. If the position of the mitotic phase coincides with the marked point, it means that the marked position is accurate. Finally, use a diamond pen to draw a circle around the intersection of the marked points on the back of the slide. In this way, the position of the mitotic phase can be determined.
[0003] As far as the existing technology is concerned, the operation of circling the split phase requires taking the slide off the microscope. The slide positioning is often inaccurate when marked by naked eyes, and it is easy to lose the area we need, which reflects the inconvenience of existing slide positioning. Utility Model Content

[0007] Furthermore, the clamping folding plate is provided with a lamp connecting column, and two of the lamp connecting columns are arranged on the same edge line of the end surface of the clamping folding plate. The two groups of laser lights are hinged on the lamp connecting columns to form cross light rays. The clamping folding plate is provided with a battery to power the laser lights.

DETAILED DESCRIPTION
[0016] In the following description, a large number of specific details are given to provide a more thorough understanding of the utility model. However, it is obvious to those skilled in the art that the utility model can be implemented without one or more of these details. In other examples, in order to avoid confusion with the utility model, some technical features known in the art are not described.
[0017] like Figure 1 As shown, a slide marking device includes a positioning frame 1, the positioning frame 1 is used to hold the slide 4, and two groups of laser lights 16 with crossed light rays are arranged on the positioning frame 1, which are used to cooperate with a microscope 3 to mark the splitting phase on the slide 4.
[0018] The utility model uses two groups of laser lights 16 with crossed light rays to mark the split phases on the glass slide 4 under the microscope 3, and clamps the glass slide 4 through the positioning frame 1, thereby realizing rapid marking of the split phases under the microscope 3. The positioning frame 1 together with the glass slide 4 can be removed from the microscope 3 without affecting the marking of the split phases by the laser lights 16, so that the diamond pen can easily carve a circle to frame the split phase on the back of the glass slide. Compared with the existing marking methods, the glass slide marking device provided by the utility model is more practical, efficient and accurate when used.
[0019] like Figure 1 and Figure 3 As shown, the positioning frame 1 includes a clamping folding plate 11, which is a thin plate structure. The structure of the clamping folding plate 11 matches the stage structure of the microscope 3, so that the positioning frame 1 is framed on the stage. The clamping folding plate 11 is provided with a single-sided limit block 12 and a frame limit block 13 for limiting the position of the glass slide 4. The frame limit block 13 is a U-shaped sheet metal structure, which is used to limit the three movement directions of the glass slide 4 in the horizontal plane. The single-sided limit block 12 fills the missing limit of the frame limit block 13 on the glass slide 4 in the horizontal plane. In particular, the edge line of the single-sided limit block 12 is rounded, which facilitates the glass slide 4 to smoothly enter the limit space formed by the single-sided limit block 12 and the frame limit block 13.
[0020] The clamping folding plate 11 is provided with a hollow groove 14 for exposing the lower surface of the slide glass 4. The hollow groove 14 is used to allow the clamping folding plate 11 placed on the stage of the microscope 3 to transmit light, and to allow the clamping folding plate 11 placed on the marking frame 2 to make way for the diamond pen to draw a circle on the back of the slide glass 4.
[0021] The clamping folding plate 11 is provided with a lamp connecting column 18, and two lamp connecting columns 18 are respectively arranged on the same side line of the upper end surface of the clamping folding plate 11. Two groups of laser lamps 16 are hinged on the lamp connecting column 18 to form cross-beams, and a battery 17 is arranged on the clamping folding plate 11 to power the laser lamps 16. The two groups of laser lamps 16 rotatably connected to the lamp connecting column 18 can make the intersection of the two light rays cover the entire range of the slide 4, meeting the need for marking the split phase on the slide 4.
[0022] The edge of the laser lamp 16 extends to the outside of the clamping folding plate 11, and the side wall of the laser lamp 16 is provided with a dial texture. The installation position and texture adjustment structure of the laser lamp 16 facilitate the use of the laser lamp 16, and the angle of the laser lamp 16 emitting light can be quickly changed.
[0023] The clamping folding plate 11 is provided with a pressure piece 15, which is used to clamp the glass slide 4 to the clamping folding plate 11. The pressure piece 15 is preferably a slidable pressure plate structure, which is convenient for quickly fixing the glass slide 4 to the clamping folding plate 11 and provides a stable condition for the diamond pen to draw a circle on the back of the glass slide 4.
[0024] like Figure 2 As shown in the figure, the slide marking device also includes a marking frame 2, which includes a marking body 22, which matches the structure of the clamping folding plate 11, and is provided with a pressing block 21 for fixing the positioning frame 1. The upper end surface of the marking body 22 is provided with a knife groove 23, which is used to make way for the diamond pen to draw a circle on the back of the slide 4. The marking frame 2 provides an operating platform for the diamond pen operation, which is convenient for the installation of the positioning frame 1, and when the positioning frame 1 is not working, the marking frame 2 is a placement frame for the positioning frame 1.
[0025] When the utility model is in use, firstly, the glass slide 4 to be observed is placed on the positioning frame 1, and then the glass slide 4 is fixed by the edge pressing piece 15; then the positioning frame 1 and the assembly of the glass slide 4 are placed on the storage table of the microscope 3, and the positioning frame 1 can be fixed by a film pressing clip; then the microscope 3 searches for the split phase on the glass slide 4, and when the split phase is found, the laser lamp 16 is powered on, and then the side wall of the laser lamp 16 is turned to make the light of the laser lamp 16 pass through the split phase, and the operation of the two groups of laser lamps 16 is repeated to make the intersection of the two groups of light fall on the split phase; then the positioning frame 1 and the assembly of the glass slide 4 are removed from the microscope 3, and placed on the marking frame 2, and the positioning frame 1 is defined by the gap between the pressing block 21 and the marking body 22; then a circle is engraved on the back of the glass slide 4 with a diamond pen, and the intersection of the two groups of light is framed with the circle, thereby framing the split phase.
