Description

Technical Field

[0001] This utility model relates to the field of embedded tissue processing technology, specifically to an embedded tissue hot-pressing and flattening device. Background Technology

[0002] Embedding machines are key equipment used in pathological experiments to process tissue samples. Their main function is to encapsulate tissue samples in embedding media such as paraffin, creating structurally stable embedded blocks for subsequent pathological analysis operations such as sectioning and staining. This is an important preliminary step in pathological diagnosis (such as cancer screening and histological analysis of diseases). However, some existing embedding machines have heat-pressing and leveling devices that lack a constant-temperature heating structure. This can easily lead to damage to the tissue sample due to overheating during processing, or the leveled tissue may be carried out or displaced during demolding, making it difficult to fix the flattened tissue. This can easily damage or carry out the tissue during use. Utility Model Content

[0003] The purpose of this invention is to provide a device for hot-pressing and flattening embedded tissues to solve the problems mentioned in the background art, such as the tissues being easily carried out or the tissue samples being damaged due to overheating.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a tissue hot-pressing and leveling device, comprising a hot-pressing block, an embedding mold, and a hot-pressing rod. A heating block is fixedly installed on the outer surface of the hot-pressing block. The hot-pressing rod is connected to the embedding machine and is located above the hot-pressing block. The embedding mold is placed on the outer surface of the embedding machine and is located below the hot-pressing block. Hot-pressing cones are uniformly fixedly arranged on the outer surface of the hot-pressing block near the embedding mold, and the hot-pressing cones are in contact with the embedding mold. The embedding mold is also in contact with the outer surface of the hot-pressing block. The outer surface of the hot-pressing cones is coated with an anti-stick coating.

[0005] Preferably, a heating film is fixedly installed on the outer surface of the hot pressing block, and a heating block is fixedly installed on the outer surface of the heating film. A temperature sensor is inserted into the side surface of the heating block and is connected to the embedding machine.

[0006] Using the above technical solution, the heating block can be heated by a heating film so that the heat can be conducted to the hot pressing block and the hot pressing cone. Then, the temperature of the hot pressing block and the hot pressing cone can be monitored by a temperature sensor. With the use of the embedding machine, the hot pressing block and the hot pressing cone can maintain a constant temperature, so that the paraffin can be fully dissolved and the tissue sample can be fixed, reducing the deformation and insecure fixation of the tissue sample caused by temperature fluctuations.

[0007] Preferably, ejector pins are slidably mounted uniformly on the outer surface of the embedding mold, and a spring pressure plate is fixedly mounted on the outer surface of one end of the ejector pin. The outer surface of the spring pressure plate is in contact with the outer surface of the embedding mold, but the outer surface of the spring pressure plate is not in contact with the outer surface of the embedding machine.

[0008] Using the above technical solution, after the sample is flattened and solidified, the spring plate can be pressed, and the ejector pin can be moved by the movement of the spring plate, so that the processed and flattened tissue sample in the embedding mold can be pushed out, making it convenient to demold and take out.

[0009] Preferably, a first screw is fixedly installed on the outer surface of the heating block, and a second screw is slidably installed on the outer surface of the first screw. Threaded sleeves are installed through the outer surfaces of the second screw and the first screw, and the threaded sleeves are threadedly connected to the second screw and the first screw, respectively. The thread directions of the first screw and the second screw are opposite.

[0010] By adopting the above technical solution, the first screw and the second screw can be moved by rotating the threaded sleeve, so as to adjust the distance between the hot pressing block and the hot pressing cone and the embedding mold, so as to be suitable for producing embedding blocks of different thicknesses and improve the practicality of the hot pressing flattening device.

[0011] Preferably, the outer surface of the threaded sleeve is fixedly provided with anti-slip texture, and the outer surfaces of the first screw and the second screw are respectively threaded with locking nuts, and the outer surface of the locking nuts is in contact with the outer surface of the threaded sleeve.

[0012] By adopting the above technical solution, the anti-slip texture can be used to easily tighten the threaded sleeve, reducing the chance of slippage when tightening the threaded sleeve. At the same time, the locking nut can lock both ends of the threaded sleeve, reducing the positional change caused by the movement of the threaded sleeve.

[0013] Preferably, a fixing nut is threaded onto the end of the second screw away from the anti-slip pattern, and a pressure sensor is threaded onto the outer surface of the second screw, with the outer surface of the pressure sensor fitting against the outer surface of the fixing nut.

[0014] By adopting the above technical solution, the components connected to the second screw can be installed and fixed through the second screw and nut, which makes it convenient to remove the second screw and replace any component when it is damaged in subsequent use, thus improving the convenience of maintenance.

[0015] Preferably, the hot-pressing rod and the pressure sensor are fixedly connected, and the pressure sensor and the hot-pressing rod are connected by bolts. The hot-pressing rod and the pressure sensor are concentrically designed, and the pressure sensor is concentrically designed with the first screw, the second screw, and the threaded sleeve.

[0016] Using the above technical solution, after the hot pressing rod is pressed down by the embedding machine, the hot pressing block and the hot pressing cone will be pressed down and inserted into the interior of the embedding mold to compress and flatten the tissue sample. At this time, the pressure sensor will monitor the compression force on the tissue sample in real time to prevent tissue damage caused by excessive compression.

[0017] Compared with the prior art, the beneficial effects of this utility model are: the embedded tissue hot-pressing flattening device:

[0018] 1. When using this device, the prepared tissue sample must first be placed inside the embedding mold. Then, the embedding machine can be activated to move the hot pressing rod, which pushes the hot pressing block and the hot pressing cone into the embedding mold to heat-press and flatten the tissue sample. This flattening process is maintained for a period of time. Afterward, the hot pressing rod can be retracted to allow the hot pressing block and the hot pressing cone to exit the embedding mold. The shape of the hot pressing cone and its non-stick coating prevent the embedding block from being carried out of the embedding mold when the hot pressing cone detaches from it, ensuring sample fixation and reducing the chance of inaccurate subsequent sectioning.

[0019] 2. Once the heating film is activated, it will heat the hot pressing block, the hot pressing cone, and the heating block. The temperature of the hot pressing block, the hot pressing cone, and the heating block will be monitored in real time by a temperature sensor to maintain the temperature of the hot pressing block and the hot pressing cone at the set value. This allows the paraffin to fully dissolve and fuse with the tissue sample, improving the quality of the embedded block and reducing the deformation or insecure fixation of the embedded block caused by excessively high or low temperatures.

[0020] 3. When it is necessary to make embedding blocks of different thicknesses and sizes, simply rotate the threaded sleeve to move the first screw and the second screw closer or further apart to adjust the distance between the hot pressing cone and the embedding mold. Then, the first screw, the second screw and the threaded sleeve can be fixed by rotating the locking nut, so that the distance between the hot pressing cone and the embedding mold will not change during use, ensuring that the embedded blocks will not be damaged.

[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0029] Please see Figure 1-6 This utility model provides a technical solution: a tissue embedding hot pressing and flattening device, including a hot pressing block 1, an embedding mold 6, and a hot pressing rod 16. A heating block 3 is fixedly installed on the outer surface of the hot pressing block 1, a heating film 4 is fixedly installed on the outer surface of the hot pressing block 1, and a heating block 3 is fixedly installed on the outer surface of the heating film 4. A temperature sensor 5 is inserted and installed on the side surface of the heating block 3, and the temperature sensor 5 is connected to the embedding machine. The hot pressing rod 16 is connected to the embedding machine and is located above the hot pressing block 1. The embedding mold 6 is placed on the outer surface of the embedding machine and is located below the hot pressing block 1. A hot pressing cone 2 is uniformly fixedly arranged on the outer surface of the end of the hot pressing block 1 near the embedding mold 6, and the hot pressing cone 2 is in contact with the embedding mold 6. The embedding mold 6 is in contact with the outer surface of the hot pressing block 1, and the outer surface of the hot pressing cone 2 is coated with an anti-stick coating.

[0030] First, the heating film 4 is activated during use, heating the hot pressing block 1, the hot pressing cone 2, and the heating block 3. Then, the temperature is monitored by the temperature sensor 5 to maintain the temperature of the hot pressing block 1, the hot pressing cone 2, and the heating block 3 at the set temperature. After that, the embedding machine presses down the hot pressing rod 16, moving the hot pressing block 1 and the hot pressing cone 2 together, allowing them to move and insert into the embedding mold 6. This forces the tissue sample placed inside the embedding mold 6 to be flattened, and the heat melts the paraffin of the tissue sample, allowing the paraffin to fully fuse and fix with the tissue sample. When the pressing is completed, the hot pressing block 1 and the hot pressing cone 2 are removed from the embedding mold 6. The shape and non-stick coating of the hot pressing cone 2 allow it to easily detach from the embedding block, greatly improving the practicality of the hot pressing leveling device.

[0031] The outer surface of the embedding mold 6 is uniformly slidably mounted with ejector pins 7, and a spring pressure plate 8 is fixedly mounted on the outer surface of one end of the ejector pin 7. The outer surface of the spring pressure plate 8 is in contact with the outer surface of the embedding mold 6, but the outer surface of the spring pressure plate 8 is not in contact with the outer surface of the embedding machine.

[0032] Next, the embedding mold 6 can be removed from the embedding machine and cooled to allow the paraffin of the embedding block to solidify. Then, the ejector pin 7 can be pushed outward by pressing the spring plate 8, allowing the embedding block to be ejected from the embedding mold 6, which greatly improves the convenience of removing the embedding block from the hot pressing device.

[0033] A first screw 9 is fixedly installed on the outer surface of the heating block 3, and a second screw 10 is slidably installed on the outer surface of the first screw 9. A threaded sleeve 11 is installed through the outer surfaces of the second screw 10 and the first screw 9, and the threaded sleeve 11 is threadedly connected to the second screw 10 and the first screw 9 respectively. The thread directions of the first screw 9 and the second screw 10 are opposite. An anti-slip texture 13 is fixedly provided on the outer surface of the threaded sleeve 11. Locking nuts 12 are threadedly installed on the outer surfaces of the first screw 9 and the second screw 10 respectively, and the outer surface of the locking nut 12 is in contact with the outer surface of the threaded sleeve 11.

[0034] Furthermore, when it is necessary to produce embedding blocks of different thicknesses, simply hold the anti-slip texture 13 and rotate the threaded sleeve 11 to move the first screw 9 and the second screw 10, allowing the first screw 9 and the second screw 10 to move closer or further apart to adjust the distance between the hot pressing cone 2 and the embedding mold 6. After adjusting the hot pressing block 1 and the hot pressing cone 2 to the appropriate position, the locking nut 12 can be rotated to fix the position of the threaded sleeve 11, thereby producing embedding blocks of different thicknesses and greatly improving the applicability of the hot pressing flattening device.

[0035] A fixing nut 15 is threaded onto the end of the second screw 10 away from the anti-slip texture 13. A pressure sensor 14 is threaded onto the outer surface of the second screw 10, and the outer surface of the pressure sensor 14 is in contact with the outer surface of the fixing nut 15. The hot-pressing rod 16 is fixedly connected to the pressure sensor 14, and the pressure sensor 14 and the hot-pressing rod 16 are connected by bolts. The hot-pressing rod 16 and the pressure sensor 14 are concentrically designed, and the pressure sensor 14 is concentrically designed with the first screw 9, the second screw 10, and the threaded sleeve 11.

[0036] Furthermore, by tightening the second screw 10 and the fixing nut 15, the second screw 10 can be connected to the pressure sensor 14. As the hot pressing rod 16 is pushed out to hot press and flatten the tissue sample, the pressure sensor 14 will monitor the pressure during hot pressing, so that the hot pressing block 1 and the hot pressing cone 2 will not excessively press the tissue sample, reducing the damage to the tissue sample caused by excessive pressure and improving the quality of the hot pressing and flattening device pressing package module.

[0037] Working principle: When making the embedding module, the embedding mold 6 is first installed on the surface of the embedding machine. Then, the heating film 4 is activated to heat the hot pressing block 1, the hot pressing cone 2, and the heating block 3. The temperature is monitored by the temperature sensor 5 to control the heating of the heating film 4, so that the temperature of the hot pressing block 1, the hot pressing cone 2, and the heating block 3 can be maintained at the set temperature. The processed tissue sample is then placed into the embedding mold 6. After that, the embedding machine presses down the hot pressing rod 16, allowing the hot pressing block 1 and the hot pressing cone 2 to be inserted into the embedding mold 6 and squeeze the tissue sample. The pressure flattens the tissue sample, and the heat from the hot pressing cone 2 allows the paraffin to fully fuse with the tissue sample. Then, the hot pressing rod 16 moves to remove the hot pressing block 1 and the hot pressing cone 2 from the embedding mold 6. The shape of the hot pressing cone 2 and the anti-stick coating allow the embedding block to detach from the hot pressing cone 2. The embedding mold 6 can then be removed and cooled. After the embedding block has cooled and solidified, the spring plate 8 is pressed to push the ejector pin 7 to move. The movement of the ejector pin 7 allows the solidified embedding module to be removed from the embedding mold 6. The embedding module can then be sliced.

[0038] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
