Description

Technical Field

[0001] The utility model relates to the technical field of embedding boxes, in particular to an embedding box which is convenient for sampling luminal tissue. Background Art

[0002] Embedding cassettes are essential consumables for pathological tissue analysis and processing. They are primarily used to hold and secure tissue samples for dehydration and as a support for embedding tissue for subsequent sectioning. Pathological specimens often include not only continuous, blocky tissue but also luminal tissue, such as the ureter, fallopian tube, and appendix.

[0003] Because existing embedding cassettes cannot hold luminal tissue upright, they are indiscriminately squeezed. This causes deformation and overlap during sectioning after sampling, dehydration, and vertical embedding. This makes it difficult to discern the luminal structure, hindering the patient's pathological diagnosis. Slices of luminal tissue, squeezed and deformed after embedding, make it difficult to discern the internal morphology of the luminal structure, hindering pathological diagnosis. Undeformed slices, on the other hand, exhibit normal morphology and can be used for pathological diagnosis.

[0004] There are also some embedding boxes in the prior art, such as the Chinese utility model patent with application number CN202323519453.9, entitled "A Special Embedding Box for ESD Specimens". It can adjust the distance between adjacent partitions by adjusting the length of the telescopic mechanism, making it easy to adjust the size of multiple storage areas at the same time and reducing the workload of the operator. However, it cannot solve the embedding needs of the above-mentioned tubular tissue.

[0005] Another example is the Chinese utility model patent application number CN202323186722.4, entitled "A Special Embedding Cassette for Pathological Specimens." By reducing the depth of the groove inside the embedding cassette and providing a pressure pad on the lid, the pathological specimen can be fixed in the embedding cassette to prevent displacement or shrinkage of the pathological specimen. However, the invention cannot solve the embedding requirements of the above-mentioned luminal tissue. Utility Model Content

[0006] In order to overcome the deficiencies of the prior art, the purpose of the present invention is to provide an embedding box that is convenient for sampling luminal tissue, can apply vertical and uniform pressure to luminal-like tissue, reduce tissue deformation, better distinguish luminal structure and carry out pathological diagnosis.

[0007] The utility model adopts the following technical solutions: an embedding box for facilitating the sampling of tubular cavity tissue, comprising: a box body assembly, a tubular cavity splint and a box cover, wherein the box cover is openably and closably arranged on the box body assembly, the tubular cavity splint is arranged inside the box body assembly, and the tubular cavity splint is used to clamp the tubular cavity tissue; the tubular cavity splint comprises a baffle, a sleeve and a spring, a plurality of clamping grooves are arranged at intervals on the inner side of the baffle, the sleeve is fixed in the clamping groove, the clamping groove and the sleeve are both semicircular, and two opposing sleeves are spliced ​​into a circular sleeve for clamping the tubular cavity tissue; a plurality of springs are arranged between the outer side of the baffle and the inner wall of the box body assembly and between two adjacent baffles.

[0008] Furthermore, the box cover includes a cover plate, the cover plate is evenly provided with through holes running through the box cover, and a plurality of support columns are fixed to the top of the cover plate.

[0009] Furthermore, the box assembly includes a box body, and box body through holes are evenly provided on the bottom end and side ends of the box body.

[0010] Furthermore, a convex ring is fixed to the edge of the bottom end of the cover plate, and a groove corresponding to the position of the convex ring is provided on the top end of the box body, so that the convex ring at the bottom end of the box body can be inserted into the groove.

[0011] Furthermore, the side ends of the baffle are evenly provided with through-holes.

[0012] Furthermore, the rear end of the box cover is hinged on the box body assembly, so that the box cover can be opened and closed on the box body assembly around the rear end hinge portion.

[0013] Furthermore, the box cover is mounted on the box body assembly via a threaded connection structure.

[0014] Furthermore, the threaded connection structure includes several connecting parts arranged at the top of the box body and several threaded knobs arranged at the top of the cover plate. A threaded hole is provided in the center of the connecting part, and the threaded column of the threaded knob is installed on the connecting part through threaded fitting.

[0015] Furthermore, the top height of the threaded knob after being mounted on the connecting portion is lower than the height of the supporting column.

[0016] Compared with the prior art, the beneficial effects of the present invention are:

[0017] 1. The utility model is an embedding cassette for facilitating the sampling of luminal tissue. The luminal tissue is placed in a sleeve, and a spring is used to stably leave a certain space between the outer side of the baffle and the inner wall of the cassette assembly, and between two adjacent baffles. This can not only maintain a stable clamping force on the luminal tissue between the circular sleeves, but also facilitate manual compression and removal of the baffles and sleeves, so that the luminal tissue is vertically and evenly compressed, reducing tissue deformation, and better distinguishing the luminal structure and conducting pathological diagnosis.

[0018] 2. The present invention provides an embedding cassette for facilitating the sampling of luminal tissue. The cassette cover and the cassette body are connected by a threaded connection structure, so that the cover plate can be accurately and relatively parallelly covered on the cassette body, avoiding the situation in which the rear end cover plate tilts and presses down on the embedded tissue at the rear portion when closing the cassette in a traditional hinged manner, resulting in uneven squeezing of the tissue. By installing and removing the cover plate parallel to the cassette body, more uniform squeezing in the vertical direction can be achieved, so that the obtained slices better reflect the actual structure of the luminal tissue, and better pathological diagnosis can be carried out.

DETAILED DESCRIPTION

[0024] The following describes the embodiments of the present invention through specific examples. Those skilled in the art will readily understand the other advantages and benefits of the present invention from the disclosure herein. The present invention may also be implemented or applied through various other specific embodiments, and the details in this specification may be modified or altered based on different perspectives and applications without departing from the spirit of the present invention. It should be noted that the following embodiments and features within these embodiments may be combined with one another, unless they conflict.

[0025] The purpose of the utility model is to provide an embedding box which is convenient for taking samples of luminal tissues in order to solve the defects of the prior art.

[0026] Example 1

[0027] This embodiment provides an embedding cassette that is convenient for sampling luminal tissue. Figure 1 As shown, it includes: a box body component 1, a tubular cavity splint 2 and a box cover 3. The box cover 3 is opened and closed and is set on the box body component 1. The tubular cavity splint 2 is set inside the box body component 1, and the tubular cavity splint 2 is used to clamp the tubular cavity tissue.

[0028] Reference Figure 4 As shown, the luminal splint 2 includes a baffle 21, a sleeve 23, and a spring 25. A plurality of clamping grooves 22 are spaced apart on the inner side of the baffle 21. The sleeve 23 is fixed in the clamping grooves 22. The clamping grooves 22 and the sleeve 23 are both semicircular in shape. Two opposing sleeves 23 are spliced ​​together to form a circular sleeve for clamping luminal tissue. Three springs 25 are provided between the outer side of the baffle 21 and the inner wall of the box assembly 1, and between two adjacent baffles 21. In this embodiment, the height of the baffle 21 is lower than the top height of the box body 11, and the top height of the box body 11 is lower than the height of the sleeve 23. The provision of the springs 25 ensures that a certain amount of space is stably maintained between the outer side of the baffle 21 and the inner wall of the box assembly 1, and between two adjacent baffles 21. This not only maintains a stable clamping force on the luminal tissue between the circular sleeves, but also allows for convenient manual compression and removal of the baffle 21 and sleeve 23. Before placing the tubular tissue in the sleeve 23, the tubular tissue can also be rolled into a tube with clean paper, and then the entire tube can be clamped in the sleeve 23 to facilitate placement and shaping, and also facilitate the subsequent separation of the sleeve 23 from the tubular tissue.

[0029] The utility model provides an embedding cassette for facilitating the sampling of luminal tissues. The sleeve 23 is used to place the luminal tissues. The spring 25 is used to stably leave a certain space between the outer side of the baffle 21 and the inner wall of the cassette assembly 1 and between two adjacent baffles 21. This can not only maintain a stable clamping force on the luminal tissues between the circular sleeves, but also facilitate manual compression and removal of the baffle 21 and the sleeve 23, so that the luminal tissues are evenly compressed, which facilitates the placement, dehydration, embedding and observation after sectioning of the luminal tissues, reduces tissue deformation, and better distinguishes the luminal structure and conducts pathological diagnosis.

[0030] The box assembly 1 includes a box body 11, and the bottom and side ends of the box body 11 are evenly provided with through box body holes 12, and the side ends of the baffle 21 are evenly provided with through baffle holes 24 for draining liquid from the tissue during dehydration.

[0031] Reference Figure 3As shown, the box cover 3 includes a cover plate 31, which is evenly distributed with through holes 32 extending therethrough. A protruding ring 34 is fixed to the bottom edge of the cover plate 31, and a groove 13 is provided at the top of the box body 11 corresponding to the position of the protruding ring 34, allowing the protruding ring 34 at the bottom end of the box body 11 to be inserted into the groove 13. Several support columns 33 are fixed to the top of the cover plate 31. The support columns 33 are distributed along the edges and center of the top of the cover plate 31. This creates gaps between the embedding cassettes when they are stacked and deliquified. The deliquated liquid can flow out through the gaps between the embedding cassettes, improving the deliquification quality of the tissue to be examined and better meeting the requirements of pathological diagnosis and testing. The top height of the threaded knob 35, after being installed on the connecting portion 14, is lower than the height of the support columns 33, so that the threaded knob 35 does not affect the support of the support columns 33.

[0032] Example 2

[0033] This embodiment provides an embedding cassette that is convenient for sampling luminal tissue. Figure 1 As shown, the rear end of the box cover 3 is hinged on the box body assembly 1, so that the box cover 3 can be opened and closed on the box body assembly 1 around the rear end hinge portion. The arrangement of the box cover 3 is the same as that of the conventional embedding box cover in the prior art, and its detailed hinge structure is not repeated.

[0034] Example 3

[0035] This embodiment provides an embedding cassette that is convenient for sampling luminal tissue. Figure 2 As shown, the box cover 3 is installed on the box body assembly 1 through a threaded connection structure. Figure 3 、 Figure 4 As shown, the threaded connection structure includes four connecting portions 14 provided at the top of the box body 11 and four threaded knobs 35 provided at the top of the cover plate 31. The connecting portion 14 has a threaded hole in its center. The threaded column of the threaded knob 35 is threadedly mounted on the connecting portion 14 to connect the cover plate 31 to the box body 11. The benefit of this connection method is that it allows the cover plate 31 to be accurately and relatively parallel to the box body 11, avoiding the traditional hinged connection method in which the rear cover plate 31 tilts and presses down on the embedded tissue at the rear, resulting in uneven compression of the tissue. This method has little effect on the embedding of ordinary tumor tissue blocks, but for luminal tissue, the tilted compression can cause the luminal structure to tilt to a certain extent, making the resulting slices not conducive to accurately reflecting the pathology of the luminal tissue. By installing and removing the cover plate 31 parallel to the box body 11, more uniform vertical compression can be achieved, so that the resulting slices better reflect the actual structure of the luminal tissue.

[0036] In addition, it should be understood that although this specification is described in terms of implementation methods, not every implementation method contains only one independent technical solution. This narrative method of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment can also be appropriately combined to form other implementation methods that can be understood by those skilled in the art.
