Specifically, the writing board 70 is fixedly arranged on the first side surface 101 of the box body 10, the included angle between the writing board 70 and the first side surface 101 is an acute angle, a sticker can be pasted on the writing board 70, and after a small biopsy specimen is placed in the box, the marked sticker can be pasted on the writing board 70; alternatively, the tablet 70 may be presented as a smooth incline, and the numbering may be done with a pencil, or may be printed using a dedicated numbering machine. Therefore, the small biopsy samples can be marked and classified conveniently, and the recorded information of each small biopsy sample can be checked conveniently. In practical use, because the first enclosure shell 301 and the second enclosure shell 303 are externally arranged, and the first filter screen 302 and the second filter screen 304 are stainless steel sheet filter screen structures, when the embedding box cover 20 is fastened with the box body 10, the first enclosure shell 301 and the second enclosure shell 303 are embedded together to form a structure with sealed periphery and through two sides, so that the sufficient permeability is ensured while the tightness is ensured to prevent the tissue from leaking, and the material exchange between the tissue and the outside in the dehydration process is facilitated; meanwhile, as the metal material is adopted as the filter screen, under the condition of ensuring permeability, the pore diameter can be smaller than that of a conventional plastic embedding box, so that the tissue cannot leak, the operation of wrapping the tissue by using gauze and filter paper can be completely cancelled, and the labor intensity of a sampling doctor can be effectively reduced. And metal material ductility, structural strength are better than plastics, therefore the filter screen can accomplish to be thin, is favorable to reagent infiltration more. When the embedding box is used for dehydration, tissues are in direct contact with reagents, materials such as filter paper and the like do not exist for blocking, the dehydration is more sufficient, the treatment effect is better, and the embedding box is particularly suitable for rapid paraffin tissue treatment.

The utility model provides a be applied to dehydration embedding box of biopsy small sample, deposit mechanism 30 through the sample in first shell 301 fixed set up in box body 10 the first filtering area 1051 of fifth side 105 to first filter screen 302 sets up in the first inside that encloses shell 301, and first filter screen 302 is located first filtering area 1051. The second enclosure 303 of the specimen storage mechanism 30 is fixedly disposed in the second filtering portion 2051 of the cover 205 of the lid 20, and the second enclosure 303 and the first enclosure 301 are attached to each other. Meanwhile, the second filter screen 304 is arranged inside the second enclosure 303, and the first filter screen 302 is located in the second filtering area 2051, so that the first enclosure 301, the first filter screen 302, the second enclosure 303 and the second filter screen 304 enclose a cavity for storing a small biopsy specimen, and after the small biopsy specimen is stored inside the cavity, the box cover 20 is covered on the box body 10 to play a role in sealing, and the small biopsy specimen can directly exchange substances with the outside through the first filter screen 302 and the second filter screen 304. And then, the tissue treatment efficiency is improved, and the small biopsy specimen is convenient to exchange substances with the outside. Therefore, the technical effects that in the tissue processing process of small tissue biopsy specimens with small volume, the sealing performance and the permeability of the embedding box can be improved simultaneously, so that the small tissue biopsy specimens can be subjected to material exchange with the outside sufficiently in the fixing and dehydrating processes without leaking out of the embedding box are achieved.

Finally, it should be noted that the above embodiments are only used for illustrating the technical solutions of the present invention and not for limiting, and although the present invention has been described in detail with reference to the examples, those skilled in the art should understand that the technical solutions of the present invention can be modified or replaced by equivalents without departing from the spirit and scope of the technical solutions of the present invention, which should be covered by the scope of the claims of the present invention.
