[0039] The present application will be further described in detail below with reference to the accompanying drawings and examples. It should be understood that the specific embodiments described herein are merely for the purpose of explaining the relevant utility model and are not intended to limit the utility model. It should also be noted that, for ease of description, only the portions relevant to the utility model are shown in the accompanying drawings.

[0040] like Figure 1-6 As shown, the utility model is a positioning and directional tissue embedding cassette, comprising a cassette body 1, and further comprising:

[0041] Positioning mechanism 2 and fixing mechanism 3; wherein:

[0042] The positioning mechanism 2 includes a first limiting groove 22 and a second limiting groove 24 on the inner side wall of the bottom plate 12. A first limiting rod 21 is movably installed in the first limiting groove 22. The movable connection of the first limiting rod 21 in the first limiting groove 22 realizes sliding movement. The sliding movement ensures the fixation and flexible adjustment of the tissue. The second limiting rod 23 and the positioning rod 25 are fixedly installed at the middle end of the first limiting rod 21. The other end of the second limiting rod 23 is movably installed in the second limiting groove 24. The second limiting rod 23 is used to further ensure the stability of the positioning mechanism 2 and prevent unnecessary displacement of the positioning mechanism 2 after the position is determined during operations such as dehydration and transparency. The positioning rod 25 is used to further ensure the stability and direction of the tissue and ensure that the tissue still maintains its original position and direction after multiple operation steps;

[0043] The fixing mechanism 3 includes a positioning hole 31 opened at the top of the inner wall of the base plate 12. The positioning hole 31 can provide multi-point fixation for the first limiting rod 21 to ensure the stability of the positioning mechanism 2. A positioning pin 32 is movably installed in the positioning hole 31. The positioning pin 32 achieves a fixing effect by insertion and can be disassembled and adjusted at any time as needed to ensure that the positioning mechanism 2 can adapt to tissues of different sizes and specifications, and prevent the tissue from sliding or shifting during operations such as dehydration and transparency.

[0044] like Figure 1 、 5 As shown, in this embodiment, it also includes a cover plate 11 arranged on the top of the box body 1, and the cover plate 11 is detachably connected to the bottom plate 12 by a clamp 111. The cover plate 11 ensures the integrity and stability of the tissue. An embedding groove 121 is longitudinally provided on the upper surface of the bottom plate 12. The embedding groove 121 is used to accommodate tissue and provide space for subsequent processing operations. A labeling platform 123 is provided at the left end of the bottom plate 12. The labeling platform 123 is used to mark tissue information during the embedding operation, especially when multiple samples need to be processed, to facilitate subsequent classification and identification. A locking bar 124 is provided on the outer wall of the right end. The locking bar 124 ensures the tight closure of the cover plate 11.

[0045] like Figure 5 、 6As shown, in this embodiment, the first limiting grooves 22 are respectively opened at the middle and upper ends of the front and rear inner walls of the embedding groove 121, and are clamped and connected with the two ends of the first limiting rod 21. Two first limiting rods 21 are provided in the embedding groove 121, and are flexibly connected with the first limiting grooves 22 by clamping. By moving the two first limiting rods 21 respectively, it is ensured that the distance in the middle can just accommodate the tissue, and the position of the directional tissue is positioned, thereby ensuring stability while having flexibility.

[0046] like Figure 5 、 6 As shown, in this embodiment, three second limiting rods 23 are evenly provided in the middle part of the first limiting rod 21 along the direction perpendicular to the first limiting rod 21. The three evenly distributed second limiting rods 23 can fix the tissue from the side over a larger area, thereby achieving stable support for the tissue. Three second limiting grooves 24 are evenly provided on the inner bottom wall of the embedding groove 121 corresponding to the position of the second limiting rod 23, which are respectively connected with the second limiting rod 23 by snapping. The three second limiting grooves 24 ensure the stability of the second limiting rod 23, so that each second limiting rod 23 can obtain effective support in the corresponding second limiting groove 24, thereby avoiding shaking during movement.

[0047] like Figure 6 As shown, in this embodiment, multiple positioning rods 25 are longitudinally arranged between the second limiting rods 23. The positioning rods 25 are used to further fix the tissue. By arranging them longitudinally, it can ensure that the tissue maintains a specific direction and position during the entire embedding process, avoiding displacement of the tissue due to liquid flow or operation vibration.

[0048] like Figure 6 As shown, in this embodiment, the bottom wall and side wall of the embedding tank 121 are provided with a plurality of strip holes 112, and the strip holes 112 can ensure that the tissue can fully contact the solution during the immersion treatment, thereby achieving dehydration and transparent treatment. The top of the front and rear side walls of the bottom plate 12 are provided with plate grooves 122, and the plate grooves 122 ensure that the upper space of the embedding tank 121 can be completely sealed when the cover plate 11 is closed, and can play a role of blocking the upper end of the positioning needle 32 to prevent the positioning needle 32 from being thrown out due to vibration or tilting during operation. , thereby affecting the stability of the positioning mechanism 2, a plurality of positioning holes 31 are longitudinally opened on the lower surface of the plate groove 122, and the positioning holes 31 pass through both ends of the first limiting rod 21 and the first limiting groove 22 and extend into the inside of the side wall of the bottom plate 12. The plurality of positioning holes 31 ensure the flexibility of the positioning mechanism 2, and pass through both ends of the first limiting rod 21 and the first limiting groove 22 and extend into the inside of the side wall of the bottom plate 12 to provide a stable fixing structure for the positioning mechanism 2, ensuring that the limiting rod will not be separated from its original position due to external force or vibration.

[0049] like Figure 1 、 2As shown in Figures 3 and 4, in this embodiment, a plurality of strip holes 112 are provided on the surface of the cover plate 11. The strip holes 112 can ensure that the tissue can fully contact the solution during the immersion treatment, thereby achieving dehydration and transparency. A lock buckle 113 is provided on the right end. The lock buckle 113 cooperates with the lock bar 124 on the right side of the base plate 12 to ensure that the cover plate 11 can be firmly locked during use to prevent it from accidentally opening or falling off during operation.

[0050] In this embodiment, the material of the second limiting rod 23 and the positioning rod 25 is a flexible material with a certain elasticity. This material can ensure that the second limiting rod 23 and the positioning rod 25 will not cause excessive pressure on the tissue when fixing it, causing tissue deformation, and at the same time have sufficient elasticity to adapt to tissues of different shapes and sizes.

[0051] The working principle and usage process of this technical solution are as follows: during use, first open the cover 11, remove the positioning pin 32, move the two first limiting rods 21 to the left and right ends of the embedding groove 121 respectively, place the tissue to be embedded in the embedding groove 121 and adjust the position and direction, then slide the two first limiting rods 21 inward to the side of the tissue, ensure that the second limiting rod 23 and the positioning rod 25 fix the tissue, and ensure that the tissue will not be shifted or flipped during the dehydration and transparency operation, then insert the positioning pin 32 to fix the position of the first limiting rod 21, close the cover 11, and place the box body 1 in a variety of solutions for dehydration, transparency and other treatments. After the soaking is completed, take out the box body 1, open the cover 11, and remove the positioning pin to easily remove the tissue.

[0052] The present invention is further described above in conjunction with the embodiments, but the present invention is not limited to the above embodiments. Various changes can be made within the knowledge of ordinary technicians in this field without departing from the purpose of the present invention.
