Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of biological tissue sampling tools, specifically to an embedding cassette for sheet-shaped specimens. Background Technology
[0002] Embedding cassettes are an indispensable part of specimen preparation, especially in the field of biomedical research. In scenarios such as pathological analysis and histological research, embedding cassettes effectively fix, process, and preserve samples for subsequent microscopic observation and diagnosis. Specifically, in the paraffin section preparation process (which typically includes steps such as dehydration, clearing, paraffin infiltration, and embedding), the application of embedding cassettes is particularly crucial.
[0003] For slide-shaped specimens of a certain thickness (i.e., samples requiring embedding for diagnosis), when preparing paraffin sections, the specimen must be perpendicular to the bottom of the embedding wax mold to obtain clear and accurate sections. This is because vertical placement helps obtain more precise and representative section results. However, in practice, slide-shaped specimens are usually laid flat in the embedding cassette. This means that when transferring the specimen from the cassette to the embedding wax mold, the operator must use tweezers to first rotate the specimen 90 degrees before sealing it in paraffin. This process not only increases the difficulty and complexity of the operation but also easily damages the specimen, affecting the quality and accuracy of the final section.
[0004] Therefore, this application proposes an embedding cassette for sheet-like specimens to solve the above-mentioned technical problems. Utility Model Content
[0005] The main purpose of this invention is to address the above-mentioned shortcomings and provide an embedding cassette for slide specimens, which enables the slide specimens to be in a vertical position within the embedding cassette, facilitating their translation into the embedding wax injection mold and improving the efficiency and quality of the entire embedding and sectioning process.
[0006] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:
[0007] An embedding cassette for sheet specimens includes a cassette body and a detachable, hinged lid at one end of the cassette body. The bottom of the cassette body is configured as a perforated grid. Multiple parallel limiting plate assemblies are vertically arranged on the grid. Each limiting plate assembly includes a fixed plate fixedly arranged on the grid and a movable plate slidably arranged on the grid, parallel to the fixed plate and with adjustable spacing.
[0008] Furthermore, the bottom of the movable plate is provided with multiple snap-fit grooves for snapping the grille, and the bottom opening end of the snap-fit groove is chamfered.
[0009] Furthermore, multiple anti-tilting sliders are fixedly installed at the bottom of the movable plate on the side away from the fixed plate, corresponding to the snap-fit groove. The bottom of the anti-tilting slider is provided with a sliding groove that communicates with the snap-fit groove, and the sliding groove is slidably snapped into the grid.
[0010] Furthermore, a reinforcing rib is fixedly provided between the top of the anti-tilt slider and the side wall of the movable plate.
[0011] Furthermore, multiple liquid permeation holes are opened on the side walls of the fixed plate and the movable plate.
[0012] Furthermore, the top of the fixed plate and the movable plate are provided with multiple clearance grooves.
[0013] Furthermore, a first baffle is fixedly provided on the side of the fixed plate facing the movable plate at both ends, and a second baffle is fixedly provided on the side of the movable plate facing the fixed plate at both ends. The second baffle is located outside the first baffle, and a gap is left between the two.
[0014] Furthermore, the movable plate has insertion holes at both ends for inserting the first baffle.
[0015] The beneficial effects of this utility model are reflected in:
[0016] This invention allows for the adjustment of the thickness of the sheet specimen to be prepared. A movable plate is slid on the grid to adjust the distance between the movable plate and the fixed plate, ensuring that the distance is greater than the thickness of the sheet specimen. The sheet specimen is then placed vertically between the fixed plate and the movable plate. Due to the limiting effect of the fixed plate and the movable plate, the sheet specimen cannot tip over and remains vertical, making it easy for subsequent operators to directly move, clamp, and seal it in paraffin wax without having to flip it over.

[0025] The technical solutions of this utility model will be clearly and completely described below with reference to the embodiments of this utility model. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. Unless otherwise specified, the embodiments and features in the embodiments of this application can be combined with each other. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.
[0026] like Figure 1-6 As shown, this utility model provides an embedding box for use in the field of sheet specimens, comprising: a box body 1 and a box cover 2 detachably hinged to one end of the box body 1. The bottom of the box body 1 is configured as a perforated grid 3. Multiple mutually parallel limiting plate assemblies 4 are vertically arranged on the grid 3. The limiting plate assembly 4 includes a fixed plate 41 fixedly arranged on the grid 3 and a movable plate 42 slidably arranged on the grid 3, parallel to the fixed plate 41 and with adjustable spacing.
[0027] In use, first adjust the distance between the movable plate 42 and the fixed plate 41 according to the thickness of the slide specimen to be prepared. Then, vertically place the slide specimen between the fixed plate 41 and the movable plate 42. Due to the limiting effect of the fixed plate 41 and the movable plate 42, the slide specimen cannot be tilted and remains vertical, which makes it easy for subsequent operators to directly move and clamp it and seal it in paraffin without having to flip it over.
[0028] In one embodiment, the bottom of the movable plate 42 is provided with a plurality of snap-fit grooves 5 for snapping the grille 3, and the bottom opening end of the snap-fit groove 5 is chamfered.
[0029] With this design, the movable plate 42 can be easily engaged with the grille 3 through the snap-fit groove 5 and can slide along the grille 3. The chamfering of the opening end of the snap-fit groove 5 is to facilitate the insertion between the snap-fit groove 5 and the grille 3.
[0030] In one embodiment, a plurality of anti-tilting sliders 6 are fixedly provided on the bottom of the movable plate 42 away from the fixed plate 41, corresponding to the snap-fit groove 5. The bottom of the anti-tilting slider 6 is provided with a sliding groove 7 that communicates with the snap-fit groove 5, and the sliding groove 7 is slidably snapped into the grille 3.
[0031] With this design, the anti-tilt slider 6 can slide together with the movable plate 42 on the grille 3, and the anti-tilt slider 6 provides a certain lateral support for the movable plate 42, preventing the movable plate 42 from easily tipping over during sliding and use, and ensuring the limiting effect produced by the cooperation between the movable plate 42 and the fixed plate 41.
[0032] In one embodiment, a reinforcing rib 8 is fixedly provided between the top of the anti-tilt slider 6 and the side wall of the movable plate 42.
[0033] This design enhances the stability of the connection between the anti-tilt slider 6 and the movable plate 42, preventing the anti-tilt slider 6 from breaking at the joint with the movable plate 42 during use.
[0034] In one embodiment, a plurality of liquid permeation holes 9 are provided on the sidewalls of the fixed plate 41 and the movable plate 42.
[0035] With this design, the liquid in the box 1 can easily immerse the sheet-like specimen between the fixed plate 41 and the movable plate 42 through the liquid permeation hole 9, ensuring the liquid's treatment effect on the sheet-like specimen.
[0036] In one embodiment, the top of the fixed plate 41 and the movable plate 42 are provided with a plurality of clearance grooves 10.
[0037] This design ensures that when tweezers are used to pick up and place sheet-like specimens between the fixed plate 41 and the movable plate 42, the clearance groove 10 provides space for the tweezers to insert downwards, preventing the fixed plate 41 and the movable plate 42 from interfering with the insertion process of the tweezers and ensuring the convenience of picking up and placing sheet-like specimens.
[0038] In one embodiment, a first baffle 11 is fixedly provided on the side of the fixed plate 41 facing the movable plate 42 at both ends, and a second baffle 12 is fixedly provided on the side of the movable plate 42 facing the fixed plate 41 at both ends. The second baffle 12 is located outside the first baffle 11, and there is a gap between the two.
[0039] With this design, the blocking effect provided by the first baffle 11 and the second baffle 12 prevents the sheet-like specimen placed between the fixed plate 41 and the movable plate 42 from moving back and forth at will, thus improving its placement stability. When the thickness of the sheet-like specimen is large, the distance between the fixed plate 41 and the movable plate 42 needs to be adjusted to a larger size, and the first baffle 11 and the second baffle 12 change from an overlapping state to a separated state, while still providing a reliable front and rear limiting effect for the sheet-like specimen.
[0040] In one embodiment, the movable plate 42 has insertion holes 13 at both ends for inserting the first baffle 11.
[0041] With this design, when the thickness of the sheet specimen is small, the distance between the fixed plate 41 and the movable plate 42 needs to be adjusted to a smaller size. At this time, the first baffle 11 is inserted into the insertion hole 13, so that the distance between the fixed plate 41 and the movable plate 42 can be reduced to close to zero, thereby improving the limiting effect of the limiting plate assembly 4 on the thinner sheet specimen and ensuring that it is in a vertical state.
[0042] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered exemplary and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention.
[0043] It should be noted that if the embodiments of this utility model involve directional indicators (such as up, down, left, right, front, back, etc.), the directional indicators are only used to explain the relative positional relationship and movement of the components in a specific posture. If the specific posture changes, the directional indicators will also change accordingly.
[0044] Furthermore, if the embodiments of this utility model involve descriptions such as "first" or "second," these descriptions are for descriptive purposes only and should not be construed as indicating or implying their relative importance or implicitly specifying the number of technical features indicated. Therefore, a feature defined with "first" or "second" may explicitly or implicitly include at least one of those features. Additionally, "multiple" refers to two or more. Furthermore, the technical solutions of the various embodiments can be combined with each other, but this must be based on the ability of those skilled in the art to implement them. If the combination of technical solutions is contradictory or impossible to implement, it should be considered that such a combination of technical solutions does not exist and is not within the scope of protection claimed by this utility model.
