[0002] Puncture-type pathological specimens refer to tissue specimens collected through puncture. Embedding refers to embedding biological samples, tissues, or cells into a supporting medium to facilitate subsequent sectioning, observation, and analysis. Puncture-type pathological specimen embedding cassettes are devices used to dehydrate embedded pathological specimens.

[0003] Chinese patent document CN222292360U discloses an embedding cassette for puncture-type pathological samples, comprising: a body having a first accommodating space, with an array of discharge holes on the bottom surface of the body; and a lid pivotally connected to the body, with a recessed protrusion on the side of the lid near the first accommodating space, and an array of inlet holes on the convex surface of the recessed protrusion; wherein, when the body and lid are closed, the recessed protrusion is located within the first accommodating space, and the side of the recessed protrusion contacts the inner side of the body; a flat second accommodating space is formed between the convex surface of the recessed protrusion and the inner bottom surface of the body for placing puncture-type pathological samples. This invention can prevent puncture-type pathological specimens from leaking out of the embedding cassette and prevent the samples from curling and deforming after dehydration.

[0004] The existing technology has the following problems:

[0005] Although the above-mentioned utility model can prevent the sample from curling and deforming, different sample sizes can cause the sample to be damaged under the pressure of the lid, and the lid is not convenient to open the embedding box because it is locked to the box body by a card plate. Utility Model Content

[0006] This invention provides a puncture-type pathological sample embedding cassette to solve the problems mentioned in the background art.

[0007] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows:

[0025] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0026] like Figure 1 - Figure 5 As shown, a puncture-type pathological sample embedding box includes a box body 1, a hinge 2 fixedly connected to the upper rear side of the box body 1, a cover plate 3 fixedly connected to the upper front side of the hinge 2, four support plates 4 arranged in a rectangular shape fixedly connected inside the cover plate 3, and a pressing mechanism 5 movably connected to the lower part of the support plate 4.

[0027] The holding mechanism 5 includes a connecting rod 52, which is slidably connected to the middle of the support plate 4. A feed plate 51 is fixedly connected to the lower part of the outer periphery of the connecting rod 52, a knob 56 is threadedly connected to the upper part of the outer periphery of the connecting rod 52, and a compression spring 55 is movably connected to the upper part of the outer periphery of the connecting rod 52.

[0028] It should be noted that the box body 1, as the main structure of the entire embedding cassette, provides a closed and stable embedding environment for the pathological sample. The hinge 2 is a key component connecting the box body 1 and the cover plate 3, allowing the cover plate 3 to be easily opened or closed when needed, facilitating sample insertion and removal. The cover plate 3 is connected to the box body 1 via the hinge 2, used to close the opening of the box body 1. The support plate 4 is rectangularly distributed inside the cover plate 3, providing stable support for the holding mechanism 5. The holding mechanism 5 is used to hold and fix the pathological sample, ensuring that the sample does not move or deform during embedding. The feed plate 51 is fixedly connected to the connecting rod 52 for holding the pathological sample. The connecting rod 52 is slidably connected in the middle of the support plate 4, connecting the feed plate 51 and the knob 56. By rotating the knob 56, the contraction range of the compression spring 55 can be adjusted, thereby adjusting the holding force on the sample. The compression spring 55 is movably connected to the upper part of the outer periphery of the connecting rod 52 to provide additional holding force, ensuring that the sample is adequately fixed during embedding.

[0029] like Figure 3 As shown, four rhomboid limiting rods 53 are fixedly connected to the upper surface of the feed plate 51. The limiting rods 53 are slidably connected inside the support plate 4, and the upper surface of the limiting rods 53 is fixedly connected to the limiting plate 54.

[0030] It should be noted that the limiting rod 53 is slidably connected inside the support plate 4, allowing the limiting plate 54 to restrict the movement range of the feed plate 51, thereby ensuring the stability and accuracy of the pressing mechanism 5.

[0031] like Figure 5 As shown, a support column 10 is fixedly connected to the lower part of the inner cavity of the box body 1, and the outer periphery of the feed plate 51 is slidably connected to the outer periphery of the support column 10.

[0032] It should be noted that the support column 10 divides the internal space of the box 1 into four parts, which can process four samples at the same time, while restricting the movement trajectory of the feed plate 51.

[0033] like Figure 1 and Figure 4 As shown, a fixing mechanism 6 is movably connected to the front side of the cover plate 3. The fixing mechanism 6 includes a connecting plate 61. The rear side of the connecting plate 61 is fixedly connected to the upper part of the front side of the box body 1. A locking plate 62 is slidably connected to the upper part of the connecting plate 61. Sliding rods 65 are slidably connected to the left and right sides of the inner cavity of the locking plate 62. Two sliding rods 63 are fixedly connected to the middle of the locking plate 62. Sliding rods 65 are slidably connected to the outer periphery of sliding rods 63. A compression spring 66 is fixedly connected to the inner cavity of sliding rods 65.

[0034] It should be noted that the fixing mechanism 6 is used to fix the cover plate 3 and the internal pressing mechanism 5. The connecting plate 61 is used to connect and fix the clamping plate 62. The clamping plate 62 slides inside the connecting plate 61 and cooperates with the slide rod 65 to fix the cover plate 3 inside the connecting plate 61. The slide rod 63 slides on the outer periphery of the slide rod 65 to limit the movement trajectory of the slide rod 65. The compression spring 66 is used to squeeze the slide rod 65 to make it engage inside the connecting plate 61.

[0035] like Figure 4 As shown, a slider 64 is fixedly connected to the upper part of the second slider 65. A groove is provided in the middle of the slider 64, and the slider 64 is slidably connected to the upper part of the card plate 62.

[0036] It should be noted that slider 64 is used to facilitate sliding of slider 65, and the groove provides a convenient operating point for facilitating the sliding of slider 64.

[0037] like Figure 2 As shown, four rectangularly distributed discharge plates 9 are fixedly connected to the bottom of the inner cavity of the box body 1, and a discharge groove 8 is provided at the bottom of the box body 1.

[0038] It should be noted that the dispensing plate 9 and the dispensing trough 8 are used to facilitate the removal of the sample after embedding. The dispensing plate 9 is at a certain height from the bottom of the box 1, allowing the reagent to remain inside the dispensing trough 8, so that the reagent can be moved away from the sample after the reaction is complete.

[0039] like Figure 1 As shown, handles 7 are fixedly connected to both the left and right sides of the cover plate 3.

[0040] It should be noted that the handle 7 makes it easy for operators to open and close the cover 3.

[0041] The working principle of this invention is as follows: The sample to be processed is placed in the groove separated by the support column 10. The cover plate 3 is rotated to allow the feed plate 51 to slide inside the box body 1. The second sliding rod 65 is squeezed to allow the clamping plate 62 to slide into the connecting plate 61. The second compression spring 66 squeezes the second sliding rod 65 to engage it inside the connecting plate 61, thereby fixing the cover plate 3. The knob 56 is rotated to adjust the extension range of the first compression spring 55. The first compression spring 55 squeezes the knob 56 to press the feed plate 51 above the sample. Then, the reagent is added into the box body through the groove in the feed plate 51, allowing the sample and reagent to react. When it is necessary to open the cover plate 3, the slider 64 is slid along the groove to move the second sliding rod 65 away from the connecting plate 61. Then, the cover plate 3 is rotated to open the box body 1.

[0042] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model.
