Abstract
Description
Technical Field
[0001] This utility model relates to the field of pathological tissue processing, and more specifically, to an embedding cassette for placing cyst wall-like tissue. Background Technology
[0002] With the development of precision medicine, the role of pathological diagnosis is becoming increasingly prominent, and the preparation of pathological slides is a crucial step in this process. The preparation of pathological slides typically involves steps such as tissue sampling, fixation, dehydration, paraffin infiltration, embedding, sectioning, and staining. Traditionally, the preparation of pathological slides requires the use of embedding cassettes. Medical staff place the tissue in the embedding cassette, process it, and then remove and embed it.
[0003] In pathological tissue processing, cyst-like tissues, due to their unique structure and morphology, are often difficult to fix and place in traditional embedding cassettes. Moreover, cyst-like tissues are very thin, and dehydration can easily lead to tissue deformation, bending, or displacement. Embedding requires using forceps to pick up each piece of tissue, determine its orientation, and embed them together, which is very time-consuming and labor-intensive. Furthermore, choosing the wrong embedding surface or having the tissues not on the same plane during embedding can affect subsequent sectioning and diagnosis. Utility Model Content
[0004] The purpose of this invention is to provide an embedding box for placing capsule wall-like tissue, which can integrate and fix the capsule wall-like tissue, position its orientation, facilitate clamping and embedding, and save time and effort.
[0005] The embodiments of this utility model are implemented as follows:
[0006] This application provides an embedding cassette for placing cyst wall-like tissue, including a cassette body and a cassette cover hinged to the cassette body. Both the cassette body and the cassette cover have dehydration holes. At least one baffle is slidably disposed inside the cassette body, and a fixing member is provided on one side of the baffle for fixing the baffle to the cassette body.
[0007] Furthermore, based on the aforementioned scheme, the two opposite inner walls of the box are respectively provided with sliding grooves, and the two ends of the baffle are respectively provided with sliders that slide in cooperation with the sliding grooves.
[0008] Furthermore, based on the aforementioned scheme, at least two slides are provided, and the number of sliders is consistent with the number of slides and corresponds one-to-one.
[0009] Furthermore, based on the aforementioned scheme, the inner wall of the box body with the sliding groove is also provided with a number of fixing grooves along its length; the fixing member is located near the fixing groove and can be inserted into the fixing groove for fixation.
[0010] Furthermore, based on the aforementioned solution, the fixing component includes a fixing block and a fixing shaft, the fixing shaft being elastically connected to one side of the baffle, and the end of the fixing shaft away from the baffle having a limiting portion with an increased cross-sectional area;
[0011] The fixing block has a sliding hole along its length, and the fixing shaft passes through the sliding hole and slides in cooperation with the sliding hole; at least one end of the sliding hole near the fixing groove has a limiting hole communicating with it; the limiting hole is adapted to the limiting part.
[0012] Furthermore, based on the aforementioned scheme, a handle is provided at the end of the limiting part away from the baffle.
[0013] Furthermore, based on the aforementioned scheme, one end of the fixed shaft is connected to the baffle via a spring, and the spring is embedded in a groove in the baffle; when the limiting part is located in the limiting hole, the spring is in its natural state.
[0014] Furthermore, based on the aforementioned scheme, the number of baffles is even, and multiple baffles are grouped in pairs, with the fixing member disposed on the opposite side of a group of baffles.
[0015] Furthermore, based on the aforementioned scheme, one of the baffles is provided with at least two of the fixing members, and the two fixing members are disposed opposite to each other at both ends of one side of the baffle.
[0016] Compared with the prior art, the embodiments of this utility model have at least the following advantages or beneficial effects:
[0017] This application utilizes dehydration holes in both the box body and lid for dehydration of cyst wall tissue. By sliding at least one baffle inside the box, the cyst wall tissue can be integrated and fixed between the baffle and the inner wall of the box body, thus defining its orientation. This facilitates the rapid clamping of multiple integrated and oriented cyst wall tissues during embedding, preventing bending or displacement of the cyst wall tissue after dehydration due to its thin structure, and avoiding incorrect clamping orientation. Alternatively, multiple baffles can be used to fix the cyst wall tissue between them. A fixing element on one side of each baffle secures it to the box body, preventing baffle displacement and thus avoiding bending or displacement of the cyst wall tissue, improving the stability of the cyst wall tissue during fixation. This application can integrate and fix cyst wall tissue, defining its orientation for easy clamping and embedding, saving time and effort. Attached Figure Description

[0026] The embodiments of this application will now be described in detail with reference to the accompanying drawings.
[0027] Please refer to Figures 1-6 The image shows a schematic diagram of the overall structure of the embedding cassette containing the cyst wall-like tissue.
[0028] This embodiment provides an embedding box for placing cyst wall-like tissue, including a box body 1 and a box cover 2 hinged to the box body 1. Both the box body 1 and the box cover 2 are provided with dehydration holes 5. At least one baffle 3 is slidably disposed inside the box body 1. A fixing member 4 is provided on one side of the baffle 3, and the fixing member 4 is used to fix the baffle 3 to the box body 1.
[0029] The following will further describe an embedding cassette for placing cyst wall-like tissue in this exemplary embodiment.
[0030] In some implementations, refer to Figure 1 The aforementioned box body 1 and box lid 2 are hinged together, and the ends of the box body 1 and box lid 2 away from the hinge are provided with a structure that allows them to be interlocked so that the box body 1 and box lid 2 can be closed. Both the box body 1 and box lid 2 are provided with dehydration holes 5, which are used for dehydration of the cyst wall-like tissue.
[0031] In a preferred embodiment, the dehydration hole 5 is a circular hole.
[0032] It should be noted that existing embedding cassettes mostly have strip-shaped pores, which are generally suitable for solid tissues. However, capsule-like tissues are relatively thin, making them prone to getting stuck in the pores, which is not conducive to their capture and embedding. By designing the dehydration holes 5 as several evenly arranged circular holes, while the rest are solid, it is possible to prevent capsule-like tissues from getting stuck between the strip-shaped pores.
[0033] In some implementations, refer to Figure 1 At least one baffle 3 is slidably disposed within the aforementioned box body 1. The baffle 3 is slidable and can move within the box body 1, thereby integrating and clamping the cyst wall-like tissue between the baffle 3 and the inner wall of the box body 1, fixing it in place. This provides support to the cyst wall-like tissue, preventing bending or displacement after dehydration, and facilitating clamping, ensuring that multiple cyst wall-like tissues are on the same plane during clamping. It also allows for pre-determining the orientation, facilitating clamping without needing to re-determine the orientation. A fixing member 4 is provided on one side of the baffle 3, used to fix the baffle 3 to the box body 1. After the cyst wall-like tissue is integrated and fixed, the baffle 3 is fixed by the fixing member 4, preventing displacement of the baffle 3 and thus preventing bending or displacement of the cyst wall-like tissue, resulting in greater stability of the cyst wall-like tissue.
[0034] As a preferred implementation method, refer to Figure 2 and Figure 3 The box 1 has two opposing inner walls with sliding grooves 11, and the baffle 3 has sliders 31 at both ends that slide in cooperation with the sliding grooves 11. The cooperation between the sliding grooves 11 and the sliders 31 can limit and guide the baffle 3, so that the baffle 3 can move stably.
[0035] In a preferred embodiment, at least two slide grooves 11 are provided, and the number of sliders 31 is the same as the number of slide grooves 11 and corresponds one-to-one. The two slide grooves 11 are arranged vertically at intervals, and the sliders 31 are arranged opposite to them, which can improve the stability of the baffle 3 when it moves.
[0036] As a preferred implementation method, refer to Figure 2The inner wall of the box 1 with the sliding groove 11 is also provided with several fixing grooves 12 along its length direction; the fixing member 4 is provided near the fixing groove 12 and can be inserted into the fixing groove 12 for fixation. By inserting the fixing member 4 into the fixing groove 12 to fix the baffle 3, the baffle 3 can be prevented from shifting, thereby preventing the cyst wall-like tissue from bending or shifting.
[0037] As a preferred implementation method, refer to Figure 4 The aforementioned fixing component 4 includes a fixing block 41 and a fixing shaft 42. The fixing shaft 42 is elastically connected to one side of the baffle 3. The end of the fixing shaft 42 away from the baffle 3 is provided with a limiting part 421 with an increased cross-sectional area. The fixing block 41 has a sliding hole 411 along its length direction. The fixing shaft 42 passes through the sliding hole 411 and slides in cooperation with the sliding hole 411. At least one end of the sliding hole 411 near the fixing groove 12 is provided with a limiting hole 412 communicating with it. The limiting hole 412 is adapted to the limiting part 421. By providing the sliding hole 411 and the fixing shaft 42 slidingly passing through the sliding hole 411, the fixing shaft 42 is connected to the baffle 3, thereby allowing the fixing block 41 to move back and forth on one side of the baffle 3, realizing the insertion and separation between the fixing block 41 and the fixing groove 12. By providing a limiting hole 412 at at least one end of the sliding hole 411 and a limiting part 421 at the end of the fixed shaft 42 away from the baffle 3, and with the fixed shaft 42 elastically connected to the baffle 3, when the fixed block 41 moves to the point where the limiting hole 412 is opposite to the limiting part 421, the limiting part 421 can extend and retract and pass through the limiting hole 412 for limiting and fixing, thereby fixing the fixed block 41 in the fixing groove 12. Alternatively, limiting holes 412 can be provided at both ends of the sliding hole 411, which can limit the fixed block 41 after it is separated from the fixing groove 12, preventing it from rotating freely.
[0038] As a preferred embodiment, the end of the limiting part 421 away from the baffle 3 is provided with a handle 422, which facilitates the control of the extension and retraction of the fixed shaft 42.
[0039] As a preferred implementation method, refer to Figure 5 One end of the aforementioned fixed shaft 42 is connected to the baffle 3 via a spring 423, which is embedded in a groove in the baffle 3. The extension and retraction of the fixed shaft 42 are mainly achieved by compressing the spring 423. The groove in the baffle 3 serves to limit and guide the fixed shaft 42, and also prevents the spring 423 from being exposed, which would affect the aesthetics. When the limiting part 421 is located in the limiting hole 412, the spring 423 is in its natural state. Even when the fixing block 41 is inserted into the fixing groove 12, the spring 423 is in its natural state, avoiding the effect of elastic force, and the limiting part 421 pops out from the limiting hole 412.
[0040] In a specific embodiment, when the fixing block 41 is fixed, the fixing shaft 42 is pressed to disengage the limiting part 421 from the limiting hole 412. At this time, the spring 423 is compressed, and the fixing block 41 is moved along the sliding hole 411 until the fixing shaft 42 is located at the other end of the fixing block 41. The fixing shaft 42 is released, so that the limiting part 421 passes through another limiting hole 412. At this time, the fixing block 41 is inserted into the fixing groove 12 to lock the baffle 3.
[0041] As a preferred implementation method, refer to Figure 6 The number of baffles 3 is even, and multiple baffles 3 are grouped in pairs. The fixing member 4 is set on the opposite side of a group of baffles 3. By setting an even number of baffles 3, the cyst wall-like tissue can be fixed between each group of baffles 3. Setting the fixing member 4 on the opposite side of each group of baffles 3 avoids affecting the fixation of the cyst wall-like tissue and also avoids damaging the cyst wall-like tissue.
[0042] As a preferred implementation method, refer to Figure 3 Each baffle 3 is provided with at least two fixing members 4, which are arranged opposite each other at both ends of one side of the baffle 3. Preferably, four fixing members 4 are provided, arranged in pairs opposite each other and spaced apart. This can improve the stability of the baffle 3.
