但上述实际操作过程中存在的问题是：由于通过注蜡嘴向包埋盒中注入蜡液时，包埋盒的外壁（如侧壁和底壁）上会存在蜡液的附着和残留，当将包埋盒转移至快速冷却台上后，由于快速降温会使包埋盒外壁上的蜡液会粘附在快速冷却台上并凝固堆积，从而在快速冷却台的表面形成凹凸不平的蜡膜，蜡膜的存在和持续的堆积不仅会影响包埋平面的平整度，而且蜡膜厚度的不均会破坏导热均匀性，影响冷却效率以及对于病理组织到的包埋质量
在包埋机台面上设置冷却槽，并且在冷却槽内注入导热且不与蜡液相溶的液体介质，正是由于液体介质导热且不与蜡液相溶的特性，在对包埋盒进行冷却过程中直接将其放置于冷却槽内的液体介质中，通过液体介质传递冷量对包埋盒中的蜡液进行快速冷却；而且由于液体介质的阻隔，使得粘附在包埋盒外壁上的蜡液不会直接与冷却槽的槽壁接触，更不会粘附与冷却槽的槽壁上而形成蜡膜，即使在频繁使用后依然不会对包埋质量产生影响，而且完全避免了工作人员清除蜡膜而增加的额外工作量，有效提升包埋效率。

Abstract
Description
Technical Field
[0001] This utility model relates to the field of medical device technology, and in particular to a cooling structure and a pathological tissue embedding machine with a cooling structure. Background Technology
[0002] Currently, pathology departments use tissue embedding machines to embed a large number of surgical pathology specimens. To ensure the timeliness of pathology reports, high requirements are placed on the quality and efficiency of the embedding work.
[0003] The main procedure for embedding pathological tissue is as follows: The pathological tissue section is placed in an embedding cassette (with an open top). The cassette is then placed below the injection nozzle on the pathological tissue embedding machine. A small amount of molten paraffin is injected into the cassette through the injection nozzle. The cassette is then transferred to the rapid cooling stage on the machine to solidify the paraffin, thus providing initial fixation for the pathological tissue. Next, the cassette is moved back below the injection nozzle, and more paraffin is injected until the cassette is completely filled (at this point, the pathological tissue is completely covered by paraffin). The paraffin is then completely cooled and solidified, and the paraffin block can be removed, completing the embedding of the pathological tissue. However, the problem in the actual operation is that when wax is injected into the embedding box through the injection nozzle, wax will adhere to and remain on the outer wall (such as the side wall and bottom wall) of the embedding box. When the embedding box is transferred to the rapid cooling stage, the rapid cooling will cause the wax on the outer wall of the embedding box to adhere to the rapid cooling stage and solidify and accumulate, thus forming an uneven wax film on the surface of the rapid cooling stage. The presence and continuous accumulation of the wax film will not only affect the flatness of the embedding plane, but the unevenness of the wax film thickness will also destroy the heat conduction uniformity, affecting the cooling efficiency and the embedding quality of pathological tissues.
[0004] Faced with the presence of a wax film on the rapid cooling stage, staff can only ensure the normal operation of the stage by manually cleaning the wax film. However, due to the huge number of pathological tissues handled every day, this undoubtedly increases the workload of the staff, reduces the embedding efficiency, and if the wax film is not cleaned in time, it may lead to a decline in the embedding quality of the pathological tissues.
[0005] In related technologies, when using a pathological tissue embedding machine to embed pathological tissues, residual wax on the embedding cassette forms a wax film on the surface of the rapid cooling stage, resulting in a decrease in embedding efficiency and quality. Currently, no effective solution has been provided.
[0006] Therefore, this utility model proposes a cooling structure and a pathological tissue embedding machine with a cooling structure to overcome the defects of the prior art. Utility Model Content
[0007] The purpose of this invention is to provide a cooling structure and a pathological tissue embedding machine with a cooling structure. The cooling platform is designed as a trough, and a heat-conducting medium that is not miscible with the wax liquid is injected into the trough-shaped cooling platform. This effectively avoids the formation of a wax film on the surface of the cooling platform during the cooling process, improves embedding efficiency, and ensures embedding quality.
[0008] The objective of this utility model can be achieved through the following solutions: This utility model provides a cooling structure, which includes a cooling tank disposed on the table of an embedding machine. The cooling tank is used to contain a thermally conductive liquid medium that is not miscible with wax liquid. A first refrigeration element is provided below the table of the embedding machine and opposite to the cooling tank. The first refrigeration element is used to cool the tank wall of the cooling tank. The embedding machine platform has a drain channel, one end of which has an inlet that communicates with the cooling tank. A plug is installed at the inlet, and the other end of the drain channel has an outlet.
[0009] In a preferred embodiment of the present invention, a liquid suction component is provided in the drain channel, which is used to draw the liquid medium in the cooling tank into the drain channel when the blockage is opened.
[0010] In a preferred embodiment of this utility model, the liquid outlet is connected to the lower part of the embedding machine platform, and a recovery container is provided below the embedding machine platform and at a position opposite to the liquid outlet.
[0011] In a preferred embodiment of the present invention, the cooling tank is a rectangular groove, the bottom wall of the cooling tank is parallel to the surface of the embedding machine, and the height difference between the bottom wall of the cooling tank and the surface of the embedding machine is 3mm to 5mm.
[0012] This utility model provides a pathological tissue embedding machine with a cooling structure, the pathological tissue embedding machine including an embedding machine table, the embedding machine table having the aforementioned cooling groove.
[0013] In a preferred embodiment of the present invention, the pathological tissue embedding machine further includes a wax injection container, the wax injection container is provided with a wax injection nozzle, the embedding machine table surface and located below the wax injection nozzle are provided with a wax injection boss, the wax injection boss is provided with a positioning recess for positioning the embedding box. The embedding machine table has a first heating element located below the wax injection boss at a position opposite to the wax injection boss. The first heating element is used to maintain the wax injection boss at a preset temperature.
[0014] In a preferred embodiment of the present invention, the embedding machine table has a first groove for accommodating an embedding box and a second groove for accommodating pathological tissue. A first cover plate and a second cover plate are respectively provided at the top opening of the first groove and the top opening of the second groove. A second heating element is provided in the first groove.
[0015] In a preferred embodiment of the present invention, the embedding machine table has a cooling platform, which is used to cool the embedded pathological tissue.
[0016] In a preferred embodiment of the present invention, a second refrigeration element is provided below the embedding machine table and opposite to the cooling table, the second refrigeration element being used to cool the cooling table.
[0017] In a preferred embodiment of the present invention, the embedding machine table has a mounting base, the mounting base is provided with a plurality of receiving slots, and a clamping tool is placed in the receiving slot.
[0018] As described above, the features and advantages of the cooling structure and the pathological tissue embedding machine with the cooling structure of this utility model are: A cooling tank is installed on the embedding machine table, and a thermally conductive liquid medium that is immiscible with the wax is injected into the cooling tank. Due to the thermally conductive and immiscible properties of the liquid medium, the embedding box is placed directly in the liquid medium in the cooling tank during the cooling process. The liquid medium transfers the cooling energy to rapidly cool the wax in the embedding box. Moreover, due to the barrier effect of the liquid medium, the wax adhering to the outer wall of the embedding box will not directly contact the tank wall, nor will it adhere to the tank wall to form a wax film. Even after frequent use, it will not affect the embedding quality, and it completely avoids the extra workload of workers removing the wax film, effectively improving embedding efficiency.
[0019] In addition, the embedding machine platform has a drain channel that connects to the cooling tank, and a plug is installed at the inlet. During normal operation, the plug seals the inlet at the connection between the cooling tank and the drain channel, ensuring that the liquid medium is stably stored in the cooling tank. After the embedding work is completed, the plug can be opened to drain the liquid medium in the cooling tank through the inlet, drain channel and outlet in sequence, so as to clean the embedding machine platform for the next use.

[0025] Implementation Method 1
[0026] like Figure 1 and Figure 2As shown, this utility model provides a cooling structure, which includes a cooling tank 2 disposed on the embedding machine table 1. The cooling tank 2 is used to contain a thermally conductive liquid medium that is not miscible with the wax liquid. A first refrigeration element is located below the embedding machine table 1 and opposite to the cooling tank 2. The first refrigeration element is used to cool the tank wall of the cooling tank 2. The embedding machine table 1 has a drain channel 3. One end of the drain channel 3 has a liquid inlet communicating with the cooling tank 2. A plug 4 is provided at the liquid inlet. The other end of the drain channel 3 has a liquid outlet 5.
[0027] In this invention, a cooling tank 2 is provided on the embedding machine table 1, and a thermally conductive liquid medium that is insoluble in wax is injected into the cooling tank 2. Due to the thermally conductive and insoluble properties of the liquid medium, the embedding box is placed directly in the liquid medium in the cooling tank 2 during the cooling process. The liquid medium transfers the cooling energy to quickly cool the wax in the embedding box. Moreover, due to the barrier of the liquid medium, the wax adhering to the outer wall of the embedding box will not directly contact the tank wall of the cooling tank 2, nor will it adhere to the tank wall of the cooling tank 2 to form a wax film. Even after frequent use, it will not affect the embedding quality, and it completely avoids the extra workload of workers removing the wax film, effectively improving the embedding efficiency.
[0028] In addition, the embedding machine platform 1 has a drain channel 3 connected to the cooling tank 2. The cooling tank 2 provides a stable temporary storage space for the liquid medium, avoiding the need for repeated replenishment due to liquid loss. A plug 4 (such as a rubber block) is installed at the liquid inlet. During normal operation, the plug 4 seals the liquid inlet at the connection between the cooling tank 2 and the drain channel 3, ensuring that the liquid medium is stably stored in the cooling tank 2. After the embedding work is completed, the plug 4 can be opened to drain the liquid medium in the cooling tank 2 through the liquid inlet, the drain channel 3 and the outlet 5 in sequence, so as to clean the embedding machine platform 1 for the next use.
[0029] In this invention, the first cooling element can be, but is not limited to, a cooling plate or a hydraulic cooling element. Of course, other cooling devices can also be used to achieve rapid cooling and quickly solidify the wax in the embedding box. The structure and cooling principle of the first cooling element are not limited here.
[0030] In this invention, the liquid medium used may be, but is not limited to, water or alcohol.
[0031] In an optional embodiment of this utility model, a liquid suction component is provided in the drain channel 3. The liquid suction component is used to draw the liquid medium in the cooling tank 2 into the drain channel 3 when the blockage 4 is open. Since the cooling tank 2 is small and can only hold a small amount of liquid medium, it is difficult for the liquid medium to be discharged by its own flow. Therefore, it is necessary to provide a liquid suction component in the drain channel 3 to draw the liquid medium into the drain channel 3.
[0032] The absorbent component can be, but is not limited to, a tampon. It can fill the entire drainage channel 3 to ensure that the liquid medium is introduced to the outlet 5 for external discharge. Of course, during the external discharge process, some liquid medium will remain in the absorbent component. After completing the embedding work, the operator only needs to replace the absorbent component or remove it and wring out the liquid medium.
[0033] Furthermore, the liquid outlet 5 is connected to the lower part of the embedding machine platform 1. A recovery container (not shown) is provided below the embedding machine platform 1 and opposite to the liquid outlet 5. The liquid medium discharged from the liquid outlet 5 is directly recovered through the recovery container.
[0034] Specifically, such as Figure 1 and Figure 2 As shown, the cooling tank 2 is a rectangular groove, and its bottom wall is parallel to the embedding machine table 1 so that the embedding box can be placed inside the cooling tank 2. The height difference between the bottom wall of the cooling tank 2 and the embedding machine table 1 is 3mm to 5mm. Within this height difference range, it ensures that the liquid medium injected into the cooling tank 2 can transfer cooling energy to achieve rapid cooling of the wax liquid, without affecting the cooling efficiency due to excessive liquid medium in the cooling tank 2. Furthermore, it ensures that the embedding box is placed stably in the liquid medium of the cooling tank 2, preventing tilting or tipping, thus ensuring the smooth progress of the embedding operation.
[0035] In this invention, the walls of the cooling tank 2 may be made of, but are not limited to, stainless steel.
[0036] In an optional embodiment of this utility model, a sealing strip (not shown) is provided at the top edge of the cooling tank 2. The sealing strip can seal the cooling tank 2 and the body of the embedding machine to prevent leakage of liquid medium.
[0037] The features and advantages of the cooling structure of this utility model are as follows: This cooling structure can rapidly cool the wax liquid in the embedding box through the liquid medium in the cooling tank 2; and due to the barrier of the liquid medium, the wax liquid adhering to the outer wall of the embedding box will not directly contact the tank wall of the cooling tank 2, nor will it adhere to the tank wall of the cooling tank 2 to form a wax film. Even after frequent use, it will not affect the embedding quality, and completely avoids the extra workload caused by the staff to remove the wax film, effectively improving the embedding efficiency.
[0038] Implementation Method 2
[0039] like Figure 1 and Figure 2 As shown, this utility model provides a pathological tissue embedding machine with a cooling structure. The pathological tissue embedding machine includes an embedding machine table 1, on which the aforementioned cooling tank 2 is provided.
[0040] In one optional embodiment of this utility model, such as Figure 1 and Figure 2 As shown, the pathological tissue embedding machine also includes a wax injection container 11, which is used to store liquid wax. Alternatively, the wax injection container 11 can also store wax blocks, which are heated to form liquid wax before being discharged. The wax injection container 11 is equipped with a wax injection nozzle 7. The embedding machine table 1, located below the wax injection nozzle 7, has a wax injection boss 6. The wax injection boss 6 has a positioning recess 601 for positioning the embedding cassette. During the wax injection process, the embedding cassette can be placed on the wax injection boss 6, so that the bottom of the embedding cassette is embedded in the positioning recess 601, thereby positioning the embedding cassette and ensuring that the liquid wax output from the wax injection nozzle 7 accurately falls into the embedding cassette.
[0041] Furthermore, a first heating element is located below the embedding machine table 1, opposite the wax injection boss 6. The first heating element can heat the wax injection boss 6 to maintain it at a preset temperature, thereby preventing the wax from solidifying rapidly during the wax injection process. The first heating element may be, but is not limited to, an electric heating wire.
[0042] In one optional embodiment of this utility model, such as Figure 1 As shown, the embedding machine table 1 has at least one cooling platform 8, which is used to cool the embedded pathological tissue. A second cooling element is located below the embedding machine table 1, opposite to the cooling platform 8, and is used to cool the cooling platform 8.
[0043] In this embodiment, the second cooling element may be, but is not limited to, a cooling plate or a hydraulic cooling element. Of course, other cooling devices may also be used to achieve rapid cooling, ensuring that the paraffin block is completely solidified after embedding, and ensuring stable encapsulation of pathological tissues. The structure and cooling principle of the second cooling element are not limited here.
[0044] In one optional embodiment of this utility model, such as Figure 1 As shown, the embedding machine table has a first groove for batch accommodating embedding cassettes and a second groove for batch accommodating pathological tissues. A first cover plate 12 is provided at the top opening of the first groove, and a second cover plate 13 is provided at the top opening of the second groove. A second heating element is provided inside the first groove. After the embedding process is completed, the wax block coated with pathological tissue is removed from the embedding cassette. An empty embedding cassette can be placed in the first groove, and the space inside the first groove is heated by the second heating element, thereby melting the residual wax block adhering to the embedding cassette and flowing into the first groove. In some embodiments, a small amount of wax liquid can be added to the first groove. The heat conduction of the wax liquid makes it easier to remove the residual wax block on the embedding cassette, and the melted wax liquid flowing into the first groove can continue to be used for heat conduction, realizing the full utilization of the residual wax liquid. The second heating element can be, but is not limited to, an electric heating wire.
[0045] In this embodiment, the paraffin used for embedding has a melting point of less than or equal to 75°C. Therefore, the highest temperature in the first groove can be controlled within the range of 75±2°C.
[0046] In one optional embodiment of this utility model, such as Figure 1 and Figure 2 As shown, the embedding machine table 1 and the wax injection container 11 are respectively provided with mounting seats 9 on both sides. The mounting seats 9 are provided with multiple receiving slots 901. The receiving slots 901 can be filled with gripping tools 10. During the embedding process, the embedding box can be gripped and transferred by the gripping tools 10. The gripping tools 10 can be, but are not limited to, tweezers.
[0047] The pathological tissue embedding machine of this invention has the same features and advantages as the cooling structure described above, and will not be repeated here.
[0048] It should be noted that in the description of this application, the terms "first," "second," etc., are used only for descriptive purposes and to distinguish similar objects; there is no order between them, nor should they be construed as indicating or implying relative importance. Furthermore, in the description of this application, unless otherwise stated, "multiple" means two or more.
[0049] The various embodiments described in this specification are presented in a progressive manner. The same or similar parts between the embodiments can be referred to each other. Each embodiment focuses on the differences from other embodiments.
[0050] The above are merely several embodiments of this utility model. Although the embodiments disclosed in this utility model are as described above, the content is only for the purpose of facilitating understanding of this utility model and is not intended to limit this utility model. Any equivalent changes and modifications made by those skilled in the art without departing from the concept and principles of this utility model should fall within the protection scope of this utility model.
