Those skilled in the art should understand that these implementation manners are only used to explain the technical principle of the present utility model and are not intended to limit the protection scope of the present utility model.

[0031] Embodiment 1:

[0032] The present utility model provides a multi-functional template, which includes a rectangular template body 3. Ten rectangular cells 31 are opened on the template body 3. The integrated embedding box 5 is embedded in the cell 31, and the integrated embedding box 5 can be clamped in the cell 31. The ten cells 31 are arranged in two rows, with five cells 31 in each row. A plurality of rectangular holes 32 are opened in the middle position of the template body 3, and the plurality of rectangular holes 32 are arranged in a row. The two rows of cells 31 are respectively arranged on both sides of the rectangular hole 32.

[0033] Strip holes 33 are opened on the two side walls of the long side of the template body 3, with five strip holes 33 on each side wall, and each strip hole 33 corresponds to one cell 31.

[0034] An extension edge is integrally arranged on one side of the integrated embedding box 5 close to the rectangular hole 32. The extension edge is suspended, that is, the extension edge is equidistant from the bottom surface of the template body 3. By setting the extension edge, it is convenient to pick out the integrated embedding box 5 from the cell 31. It also includes a demoulding shell 6. A demoulding column 61 is fixedly connected to the inside of the demoulding shell 6 corresponding to the rectangular hole 32. The demoulding column 61 is used to jack up the extension edge, so as to achieve the purpose of jacking up the integrated embedding box 5 from the cell 31.

[0035] It should be noted that the number of cells 31 is not limited to ten, and the number of cells 31 can be appropriately adjusted according to the actual use situation.

[0036] In use, place the tissue sample into the integrated embedding cassette 5, and then embed the integrated embedding cassette 5 into the cell 31. Multiple integrated embedding cassettes 5 can be embedded into multiple cells 31 at the same time. Then immerse the template body 3 into alcohol, and the dehydration of the tissue samples in multiple integrated embedding cassettes 5 can be achieved simultaneously. Immerse the template body 3 into liquid paraffin, and the embedding of the tissue samples in multiple integrated embedding cassettes 5 can be achieved simultaneously. Through the action of the rectangular hole 32 and the strip hole 33, the excess paraffin and alcohol in the cell 31 can be filtered out. After the embedding is completed, embed the template body 3 into the demolding shell 6, and make the demolding column 61 pass through the rectangular hole 32 to lift the outer extension edge, so as to achieve the purpose of demolding ten integrated embedding cassettes 5 at the same time.

[0037] Embodiment 2:

[0038] The present utility model also provides a fully enclosed tissue dehydration, embedding, and cooling integrated machine, which includes a telescopic mechanism 1. The telescopic mechanism 1 is vertically arranged and can be telescoped up and down. The top of the telescopic mechanism 1 is connected to a bracket mechanism 2. The template as described in Embodiment 1 is detachably connected to the bracket mechanism 2. A multi-functional liquid cylinder 4 is arranged below the bracket mechanism 2. The top of the multi-functional liquid cylinder 4 is open, and the telescopic mechanism 1 can drive the bracket mechanism 2 to extend into the multi-functional liquid cylinder 4.

[0039] An inlet 41 and an outlet 42 are provided on the side wall of the multi-functional liquid cylinder 4. Alcohol and liquid paraffin can be injected into the multi-functional liquid cylinder 4 through the inlet 41 respectively, and the liquid in the multi-functional liquid cylinder 4 can be discharged through the outlet 42.

[0040] The telescopic mechanism 1 includes a first-level frame 11. The bottom of the first-level frame 11 is fixed to the bottom plate. A second-level frame 12 is connected to the first-level frame 11 through a chute and a slide rail, and the second-level frame 12 can slide up and down relative to the first-level frame 11. A third-level frame 13 is connected to the side surface of the second-level frame 12 facing away from the first-level frame 11 through a chute and a slide rail, and the third-level frame 13 can slide up and down relative to the second-level frame 12. An installation plate 14 is connected to the side surface of the third-level frame 13 facing away from the second-level frame 12 through a chute and a slide rail, and the installation plate can slide up and down relative to the third-level frame 13.

[0041] A hydraulic cylinder 111 is fixedly connected to the bottom of the first-level frame 11. The hydraulic cylinder 111 is vertically arranged, and the output end of the hydraulic cylinder 111 is fixedly connected to the bottom of the second-level frame 12 for driving the second-level frame 12 to move up and down relative to the first-level frame 11. A hydraulic cylinder 121 is fixedly connected to the bottom of the second-level frame 12. The hydraulic cylinder 121 is vertically arranged, and the output end of the hydraulic cylinder 121 is fixedly connected to the bottom of the third-level frame 13 for driving the third-level frame 13 to move up and down relative to the second-level frame 12. A hydraulic cylinder 131 is fixedly connected to the bottom of the third-level frame 13, and the output end of the hydraulic cylinder 131 is fixedly connected to the bottom of the mounting plate 14 for driving the mounting plate 14 to move up and down relative to the third-level frame 13.

[0042] The bracket mechanism 2 is rotatably connected to the mounting plate 14. A driving device 141 is installed on the surface of the mounting plate 14 facing away from the bracket mechanism 2. The driving device 141 is a motor, and the output end of the driving device 141 is fixedly connected to the bracket mechanism 2 for driving the bracket mechanism 2 to rotate.

[0043] A protective shell 15 is sleeved on the first-level frame 11, the second-level frame 12, the third-level mining machine, and the mounting plate 14. The protective shell 15 is composed of multiple layers of telescopic shells, and the protective shell 15 can protect the first-level frame 11, the second-level frame 12, the third-level mining machine, and the mounting plate 14.

[0044] The bracket mechanism 2 is arranged outside the protective shell 15. The bracket mechanism 2 includes a support box 21. One side surface of the support box 21 close to the mounting plate 14 is rotatably connected and fixedly connected to the driving device 141, and the support box 21 can rotate relative to the protective shell 15. A plurality of hydraulic cylinders 22 are arranged in the support box 21. The hydraulic cylinders 22 are fixed in the support box 21 and are vertically arranged. The output end of the hydraulic cylinder 22 is fixedly connected to a right-angle frame 23. One end of the right-angle frame 23 facing away from the hydraulic cylinder 22 extends out of the support box 21 and is welded with a mounting frame 24. The mounting frame 24 is adapted to the template body 3, and the template body 3 is detachably connected to the mounting frame 24.

[0045] On the lower surface of the template body 3, a square top column 34 is slidably connected to each cell 31 through a chute. That is, when the five template bodies 3 are driven to approach each other by the hydraulic cylinder 22, the square top column 34 on the upper layer can press down the sample positioning plate of the integrated embedding box 5 on the lower layer, thus eliminating the need for manual pressing one by one by operators, greatly saving operation time and making the operation simpler and faster. It should be noted that the sample positioning plate of the integrated embedding box 5 on the topmost template body 3 needs to be manually pressed by the operator.

[0046] There are five mounting frames 24, which are equidistantly arranged from top to bottom. A right-angle frame 23 is welded to the middle mounting frame 24, and the other end of the right-angle frame 23 is directly fixed to the support box 21 without being connected to the hydraulic cylinder 22. Two right-angle frames 23 are welded to the other four mounting frames 24, and the two right-angle frames 23 are symmetrically arranged about the center line of the mounting frames 24.

[0047] It should be noted that, since the mounting brackets 24 are equidistantly arranged up and down, the lengths of the right-angle brackets 23 are also different, and the welding positions of the right-angle brackets 23 obtained by each mounting bracket 24 are also different, so as to avoid interference between the right-angle brackets 23 on different mounting brackets 24. The two hydraulic cylinders 22 corresponding to each mounting bracket 24 move synchronously.

[0048] It should be noted that, of the five mounting frames 24, the mounting frame 24 located in the middle position can be welded with only one right-angle frame 23, and the end of the right-angle frame 23 facing away from the mounting frame 24 can be directly welded to the support box 21, and there is no need to connect the hydraulic cylinder four 22. The present application is illustrated by setting a right-angle frame 23 on the middle mounting frame 24 and not connecting the hydraulic cylinder four 22. However, it is not limited to this. The mounting frame 24 located in the middle position can also be connected to two right-angle frames 23 and connected to the hydraulic cylinder four 22.

[0049] The hydraulic cylinder 22 can be used to change the distance between adjacent mounting racks 24 to avoid the dehydration or embedding process of the tissue sample being affected by the distance being too large or too small.

[0050] refer to Figure 11 This device is used to be installed inside a dehydrator. It should be noted that this device only replaces the original dehydration mechanism inside the dehydrator and is fixed with bolts to ensure the sealing effect of this device and prevent the liquid in the multifunctional liquid cylinder 4 from emitting irritating odor during operation.

[0051] In summary, by providing a plurality of cells 31 on the template body 3, the present utility model can simultaneously embed a plurality of integrated embedding boxes 5 on the template body 3. Thus, when the template is immersed in alcohol, dehydration of the tissue samples in the plurality of integrated embedding boxes 5 can be achieved simultaneously. Similarly, fixation, clearing, infiltration with paraffin, embedding, and cooling of the tissue samples in the plurality of integrated embedding boxes 5 can also be achieved simultaneously, greatly improving work efficiency, shortening the working hours, and avoiding errors caused by confusion as the processing is concentrated on the mold. Through the cooperation of the telescoping mechanism 1 and the bracket mechanism 2, the template body 3 can be inserted into the multi-functional liquid cylinder 4. Alcohol and liquid paraffin can be respectively injected into the multi-functional liquid cylinder 4 to complete the dehydration and embedding of the tissue samples. Pushing the bracket mechanism 2 above the multi-functional liquid cylinder 4 by the telescoping mechanism 1 can achieve the purpose of cooling, greatly shortening the production time of tissue sections. The driving device 141 can drive the bracket mechanism 2 to rotate. Thus, after dehydration, the bracket mechanism 2 can be rotated 180 degrees by the driving device 141 to make the opening of the template body 3 face downward, thereby enabling more thorough draining of the alcohol in the template body 3.
