[0028] In order to facilitate better understanding of the present application, the following examples are illustrated in combination with the drawings, and these examples belong to the protection scope of the present application, but do not limit the protection scope of the present application.
[0029] Embodiment 1
[0030] A pathological wax block cold table placing structure, as shown in Figures 1-3 , Figure 6 , comprising: a placing rack 1, a placing groove 11 is arranged at the top, and a contact groove 12 is arranged at the bottom; a partition plate 2 is arranged on the placing groove 11 and is located on both sides of the contact groove 12; adjacent two partition plates 2 divide the placing groove 11 into a plurality of wax block grooves 13; the wax block groove 13 and the contact groove 12 are in communication with each other, and the width of the wax block groove 13 is greater than the width of the contact groove 12; the wax block groove 13 and the contact groove 12 are arranged in parallel, and the horizontal center lines of the two are coincident in the vertical direction.
[0031] The height of the contact groove can be equal to the depth of the embedding box mold groove, so as to ensure that it is in contact with the cold table and improve the freezing effect.
[0032] The bottom of the placing frame can be made of cold-conducting material to facilitate the transmission of cold air to the pathological wax blocks. The cold-conducting material can be metal, and the thickness can be the same as the height of the contact groove.
[0033] When there are more pathological wax blocks on the placing frame, the placing frame is placed on the cold table for secondary freezing. After a period of time, some wax blocks may freeze on the cold table due to water. At this time, the placing frame is lifted, and some pathological wax blocks may slide. To prevent the wax blocks from sliding out of the wax block groove, the pathological wax blocks should be sunk in the wax block groove, that is, the height of the contact groove and the wax block groove can be greater than the overall height of the pathological wax blocks.
[0034] In use, the placing frame is first placed on the cold table, then the appropriate width of the contact groove is selected according to the size of the tissue end of the pathological wax block, and then the pathological wax blocks are sequentially placed on the appropriate wax block groove for secondary freezing treatment. Since the contact groove is provided to enable the tissue end of the pathological wax block to contact the cold table, and the wax blocks are placed more neatly, the cold air transmission is facilitated, and the uniform cooling is ensured. After the secondary freezing is completed, the placing frame is lifted to lift all the pathological wax blocks placed thereon, avoiding the existing single wax block taking and placing, and improving the work efficiency.
[0035] Example 2
[0036] Compared with Example 1, the following technical features are further provided:
[0037] As shown in Figure 1 , Figure 3 , the number of the contact grooves 12 is consistent with the number of the wax block grooves 13.
[0038] As shown in Figure 1 , Figure 3 , Figure 6 , the width of the contact groove 12 is slightly greater than or equal to the width of the embedding box mold groove.
[0039] As shown in Figure 1 , Figure 3 , the maximum width of the wax block groove 13 is consistent with the width of the embedding box.
[0040] The contact grooves and the wax block grooves can be provided in multiple groups, and the number of the contact grooves is equal to the number of the wax block grooves. When batch samples are processed, the multiple groups of the contact grooves and the wax block grooves can place a larger number of pathological wax blocks to meet the sample processing needs of the experiment.
[0041] In use, the tissue end of the pathological wax block is within the range of the contact groove and contacts the cold table, facilitating the cold air conduction and improving the freezing effect of the wax block.
[0042] The top of the wax block groove is used to fix the embedding box of the pathological wax block, therefore, the width of the wax block groove is consistent with the width of the embedding box, which can facilitate taking and placing; the width of the wax block groove can also be slightly larger than the width of the embedding box.
[0043] Embodiment 3
[0044] Compared with Embodiment 2, the following technical features are further provided:

[0046] As shown in Figures 3-5 , the placing structure further comprises a magnetic strip 3 embedded in the placing groove 11 and not blocking the contact groove 12; the length of the magnetic strip 3 is consistent with the length of the placing groove 11.
[0047] As shown in Figures 3-5 , the magnetic strip 3 is arranged close to the side of the contact groove 12; the number of the magnetic strip 3 is 1 times or 2 times the number of the contact groove 12.
[0048] In the initial freezing, the pathological wax block has not yet completely formed, therefore, it is placed together with the embedding box mold on the cold table for freezing; since the embedding box mold used is made of stainless steel, in order to stably place it in the placing groove, a magnetic strip is embedded in the placing groove, and the embedding box mold can be fixed in the placing groove through the magnetic attraction of the magnetic strip, so that the initial freezing can also use the placing rack, and the utilization efficiency is improved; the magnetic strip can be arranged on the placing groove close to the two sides of the contact groove, and the magnetic strip can be arranged on one side or on both sides, and the size of the magnetic strip is appropriate to be able to magnetically attract and fix the embedding box mold.
[0049] In order to avoid the sliding of the embedding box mold when the placing rack is lifted during the initial freezing, the pathological wax block (with the embedding box mold) during the initial freezing should be placed in the contact groove, that is, the height of the contact groove and the placing groove can be greater than the overall height of the pathological wax block (with the embedding box mold).
[0050] Embodiment 4
[0051] Compared with Embodiment 3, the following technical features are further provided:
[0052] As shown in Figure 1 , Figure 3 , Figure 6 , the placing structure further comprises a handle 4 arranged on both sides of the placing rack 1.
[0053] The pathological wax block can be used for HE staining, immunohistochemical staining, special staining diagnosis and molecular pathological examination and the like multiple projects, therefore, the laboratory usually has batched pathological wax block preparation, in the preparation process, the initial freezing, the secondary freezing need to repeatedly place the shelf, put down, lift and the like operation repeatedly, in order to guarantee that the experimental personnel hold steady and place the shelf, therefore set the handle, when using, the experimental personnel can hold tightly the handle of the both sides of the placing shelf, thereby can more conveniently carry out the lifting or putting down operation, improve the use convenience and operation efficiency.
