Description

TECHNICAL FIELD

[0001] The utility model relates to pathological tissue embedding box technical field especially, relate to a kind of pathological tissue embedding box of adjustable capacity size. BACKGROUND

[0002] In order to preserve the living tissue removed from the patient for pathological diagnosis and medical research, the hospital needs to make the removed living tissue into pathological paraffin specimens in time. Making pathological sections usually embeds the pathological tissue in paraffin blocks, and then cuts into thin slices with a sectioning machine, after staining, according to the microscopic observation results, pathological diagnosis is made, which is usually completed by pathologists and technicians. Tissue embedding is an important operation step in pathological section making. Before embedding, the tissue needs to be handled first, such as sampling, dehydration, transparency, and wax immersion. Usually, the pathologist is responsible for sampling, that is, the pathological tissue is placed in a plastic tissue embedding box according to a certain tissue direction. After the tissue in the embedding box is treated by dehydration, transparency, and wax immersion, the pathological technician takes out the tissue from the tissue embedding box, puts it into another stainless steel embedding device, pours in the melted wax liquid, covers the original tissue embedding box, and after the wax liquid solidifies, the tissue and the tissue embedding box are firmly fused together, and then it can be taken out for sectioning.

[0003] In pathological technology, tissue embedding treatment is the basis of pathological examination technology, and embedding box is a medical consumable used in the whole process of tissue section preparation. After being fixed by formalin and cut into appropriate size, pathological tissue is flatly stored in the embedding box. During embedding, first, the pathological tissue is flatly stored in the embedding box after being fixed by formalin and cut into appropriate size. Second, the embedding box is immersed in an alcohol solution for dehydration and defatting treatment. Then, the alcohol solution is replaced with xylene. Subsequently, the xylene is replaced with liquid paraffin, thereby obtaining paraffin-replaced pathological tissue, and finally, paraffin solidification is performed in a cold environment to obtain an embedding block.

[0004] In the pathological experiment of paraffin section, we need to put the paraffin-embedded specimen into the embedding machine to embed the specimen with the embedding box during the embedding step, form a wax block to facilitate subsequent section processing. Due to the different sizes of the specimen, the size of the embedding block needs to be selected according to the experimental requirements. In the above process, the following problems are often encountered: due to the experimental requirements, the size of the specimen embedding block needs to be selected for different embedding boxes, the embedding box needs to be replaced back and forth, different batches of embedding boxes need to be purchased at one time, which wastes financial resources and time. The embedding box currently used in the pathology department is mainly composed of a box body and a box cover, some of which are connected as a whole; some are in a separated state and are linked by embedding after being put into the tissue. At present, the embedding box used in the pathology department is mostly composed of a box body with a sieve hole and a cover, and the internal volume is fixed, which is only suitable for embedding of general volume tissue specimens and is not suitable for embedding of larger tissue specimens. The patent document with application number 202220390338.2 discloses a new type of small tissue specimen embedding box for pathology department, which has a fixed internal volume and cannot adjust the capacity size, and is only suitable for embedding of general volume tissue specimens and is not suitable for embedding of larger tissue specimens.

[0025] This invention provides an adjustable-capacity pathological tissue embedding cassette, such as... Figures 1-5 As shown, it includes a box body 1 and a box lid 2. The box body 1 has multiple limiting sliding grooves 11 on opposite sides. The box lid 2 has multiple limiting sliding posts 21 that match the limiting sliding grooves 11. The box body 1 also has slots 12 on opposite sides, and the box lid 2 has buckles 22 that match the slots 12. The buckles 22 fit tightly into the slots 12. By setting multiple limiting sliding grooves 11 and multiple limiting sliding posts 21 that match the limiting sliding grooves 11, when storing specimens of different sizes, the internal space can be dynamically adjusted simply by adjusting the different positions of the box body 1 and the box lid 2. The box lid 2 adjusts accordingly with the adjustment of the box body 1, providing strong adaptability and flexibility. Simultaneously, the buckles 22 fit tightly into the slots 12 to achieve a secure hold. Specifically, the sides of the buckles 22 and the sides of the slots 12 that cooperate with the buckles 22 can be tilted to enhance the fixing effect. The device can lock and fix the adjusted box body 1, ensuring high stability. It enables dehydration and embedding of various tissue specimens, including routine pathological tissues, large tissues, and bone tissues of different sizes and thicknesses, improving sampling speed and greatly facilitating use by pathologists. The adjustable sliding grooves 11 on both sides and the latches 22 at both ends must be matched in height to ensure that the latches 22 can engage at each height setting of the sliding grooves 11.

[0026] Preferably, in the adjustable-capacity pathological tissue embedding cassette provided by this utility model, both the limiting sliding groove 11 and the limiting sliding post 21 are triangular in structure, and the limiting sliding post 21 can be inserted into the limiting sliding groove 11.
