[0002] Tissue embedding is a crucial step in pathological, biological, and medical research. Its purpose is to encapsulate fixed, dehydrated, and paraffin-impregnated tissue samples in a supporting medium such as paraffin for subsequent sectioning, staining, and microstructural analysis. Traditional tissue embedding often uses metal or plastic embedding boxes as containers, and achieves tissue positioning and solidification by pouring in molten paraffin and cooling it to form a solid shape.

[0003] The existing embedding cassette mainly consists of a body and a lid. Specifically, the bottom surface of the body and the lid are evenly provided with holes as ventilation holes.

[0004] However, existing embedding cassettes have the following problems:

[0005] When existing embedding cassettes need to be recycled after use, the lid and body of the cassette need to be cleaned. However, the cassette body is used in conjunction with paraffin to complete the embedding, and the complex gap structure formed at the bottom of the cassette body due to its functional design becomes a "reservoir" of contaminants after repeated use. The paraffin crystals (melting point 60-70℃), denatured tissue proteins and dye molecules that remain inside form a three-dimensional network cross-linked structure during high-temperature sterilization, which makes it difficult to clean the residue on the bottom of the cassette body.

[0006] Therefore, this solution proposes a tissue embedding cassette to address the aforementioned issues. Summary of the Invention

[0029] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with Figures 1 to 6. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0030] It should be noted that if there are directions involved in the embodiments of the present invention, they shall be subject to those shown in the drawings. For example, the front and the rear are based on Figure 1. Specifically, the left side of Figure 1 is the front, and the right side of Figure 1 is the rear. At the same time, as shown in Figure 2, the horizontal direction is generally the left-right direction, and the vertical direction shown in the figure is the up-down direction. If a specific posture changes, the directional indication shall also change accordingly.

[0031] Referring to Figures 1-6, the present invention provides a tissue embedding box, which includes a box body 1 and a box cover 2. A support frame 8 is installed below the inner cavity of the box body 1. Positioning blocks 7 are respectively installed on the left and right sides of the top surface of the support frame 8. A bottom plate 4 is slidably arranged between the two positioning blocks 7. Elastic pieces 10 are symmetrically installed on one side of the bottom surface of the box cover 2. Clamping grooves 9 are symmetrically opened on one side of the top surface of the box body 1. The elastic pieces 10 are respectively clamped in the two clamping grooves 9. The elastic pieces 10 are made of metal or plastic with a reset performance, and the shape is "L", which is convenient for the elastic pieces 10 to be clamped and separated from the clamping grooves 9;

[0032] Among them, a plurality of ventilation holes are uniformly opened on the bottom plate 4 and the box cover 2.

[0033] In a further embodiment, referring to Figures 1-3, the upper parts between the front and rear side walls of the positioning block 7 are in a "V" shape, and the lower parts of the front and rear side walls of the positioning block 7 are vertically designed, and anti-slip patterns are provided on the vertical parts;

[0034] Grooves 5 are respectively opened on the left and right sides of the bottom plate 4. The positioning blocks 7 slide in the grooves 5. An insertion slot 6 is opened on the top surface of the box body 1. The insertion slot 6 is in a "U" shape. A limiting frame 11 is installed on the bottom surface of the box cover 2. The limiting frame 11 is in a "U" shape. The limiting frame 11 is clamped in the insertion slot 6;

[0035] In this embodiment, the shape design of the positioning block 7 facilitates the sliding of the groove 5 on the base plate 4 with the positioning block 7. When the groove 5 slides to the position of the vertical side wall of the positioning block 7, the inner wall of the groove 5 and the positioning block 7 come into contact with each other. The anti-slip texture prevents the base plate 4 from falling off.

[0036] In a further embodiment, referring to Figures 1-6, the snap-fit ​​groove 9 is L-shaped, and the top surface and rear side of the snap-fit ​​groove 9 are respectively connected to the outside of the box body 1. A disassembly component 3 is installed on the rear side wall of the box body 1, and the disassembly component 3 includes a connecting bracket 301.

[0037] The connecting frame 301 is symmetrically installed on the rear side wall of the box 1. The connecting frame 301 has a moving groove 303. A push plate 305 is slidably installed in the moving groove 303. The left and right outer walls of the connecting frame 301 have sliding grooves 302 respectively. The left and right sides of the push plate 305 are respectively connected to the limit block 304.

[0038] A pressing plate 306 is installed on the side of the push plate 305 away from the box body 1;

[0039] In this embodiment, when the device needs to be cleaned after use and reused, the groove 5 is pushed out from below, so that the groove 5 on the bottom plate 4 can slide out on the positioning block 7, thereby separating the box body 1 and the bottom plate 4. This makes it easy to disassemble and clean the bottom plate 4 and the box body 1, avoiding the problem of blind spots that increase the difficulty of cleaning in the traditional one-piece box design, and achieving the effect of improving cleaning efficiency.

[0040] In a further embodiment, referring to Figures 1-3, the front panel of the box 1 is designed to be inclined;

[0041] The slanted design on the front of box 1 makes it easier to write experiment numbers.

[0042] The working principle of this utility model is as follows: When using the device to store the extracted tissue, the extracted tissue is placed on the base plate 4, and then the limiting frame 11 on the bottom surface of the box cover 2 is aligned with the insertion groove 6 on the top surface of the box body 1, and the spring piece 10 on the bottom surface of the box cover 2 is aligned with the snap-fit ​​groove 9 on the top surface of the box body 1 for insertion.

[0043] As the snap-fit ​​groove 9 and the spring piece 10 are inserted into each other, the spring piece 10 will snap into the snap-fit ​​groove 9, thereby sealing the extracted tissue in the box body 1, the bottom plate 4 and the box cover 2.

[0044] When it is necessary to extract tissue from the device for embedding, the pressing plate 306 is pressed to push the pushing plate 305 to press the spring piece 10, thereby releasing the mutual locking between the locking groove 9 and the spring piece 10, so as to facilitate the separation of the box cover 2 and the box body 1 for embedding.

[0045] When the device needs to be cleaned after use so that it can be reused;

[0046] The groove 5 is pushed out from below, allowing the groove 5 on the base plate 4 to slide out on the positioning block 7, thereby separating the box body 1 and the base plate 4. This facilitates disassembly and cleaning of the base plate 4 and the box body 1, avoiding the problem of blind spots that increase cleaning difficulty in traditional one-piece box designs, and thus improving cleaning efficiency.

[0047] Based on the disclosure and teachings of the above specification, those skilled in the art can make changes and modifications to the above embodiments. Therefore, this utility model is not limited to the specific embodiments disclosed and described above, and such modifications and changes should also fall within the protection scope of the claims of this utility model. Furthermore, although some specific terms are used in this specification, these terms are only for convenience of explanation and do not constitute any limitation on this utility model.
