[0002] In the field of biomedical research, the accurate analysis and efficient processing of biological tissues are key steps to promote scientific research progress and clinical applications. However, traditional biological tissue processing methods, such as manual cutting, smashing, etc., have many limitations and are difficult to meet the high standards and strict requirements of modern biomedical research. The following are the deficiencies of existing biomedical tissue smashing devices in several key aspects, which have promoted the research and improvement of new smashing devices:

[0003] 1. Complicated operation and low efficiency:

[0004] Manual operation: Many existing biomedical tissue smashing devices still rely on manual operation to open and close the feed inlet. This not only increases the labor intensity of operators but also may lead to errors and inconveniences during the operation process.

[0005] Time consumption: Manually cutting and smashing biological tissues is a time-consuming and complicated process, especially when dealing with a large number of samples, the efficiency is particularly low.

[0006] 2. Difficult to ensure hygienic conditions:

[0007] Risk of cross-contamination: Deficiencies in manual operation and device design may lead to cross-contamination of biological tissues during the processing, which is a serious risk for an experimental environment that requires a high level of cleanliness.

[0008] Difficult to clean and disinfect: The complex structure design of some devices makes it difficult to carry out thorough cleaning and disinfection, thus increasing the risk of hygienic problems.

[0009] 3. Inconvenient collection and removal of tissues:

[0010] Backward collection method: Some devices lack an efficient and convenient collection system when collecting the smashed tissues, resulting in easy loss or damage of tissue samples.

[0011] Difficult to remove: The design of some devices makes it difficult to remove the smashed tissues, which increases the operation difficulty and time cost of operators. Summary of the Invention

[0021] In a possible design, the limiting component includes two positioning rods symmetrically arranged and fixedly connected to the bottom of the inner rectangular block. The positioning rods are engaged with the positioning grooves. One side of the top of the inner rectangular block is fixedly connected with a triangular plate, which is used in cooperation with the side plate. A second round hole is opened inside the inner rectangular block, and an arc hole is opened at the top of the inner rectangular block. The arc hole is communicated with the second round hole. A third relief groove is opened on one side of the inner rectangular block, which is used in cooperation with the second rack. An annular groove matched with the collection box is opened at the bottom of the inner rectangular block.

[0022] In a possible design, the crushing component includes a servo motor fixedly connected to the bottom of the sliding plate. The output shaft of the servo motor rotates through the sliding plate and is fixedly connected with a second gear. A third rotating shaft rotates through the inside of the sliding plate. A third gear meshing with the second gear is fixedly sleeved on the outer wall of the third rotating shaft. A plurality of crushing knives are fixedly sleeved on the outer wall of the third rotating shaft.

[0023] In a possible design, the feeding component includes a rectangular hole opened at the bottom of the U-shaped plate. The same first rotating shaft is rotatably connected between the inner walls on both sides of the rectangular hole. A rotating plate is fixedly sleeved on the outer wall of the first rotating shaft. Two symmetrically arranged fixing blocks are fixedly connected to the inner wall of the bottom of the U-shaped plate. The same compression spring is fixedly connected between the bottom of the fixing block and the top of the rotating plate.

[0024] In a possible design, the blocking component includes two symmetrically arranged sliding grooves opened on one side of the device housing. A slider is slidably connected inside the sliding groove. The same spring is fixedly connected between the top of the slider and the inner wall of the top of the sliding groove. The same sliding baffle is fixedly connected to one side of the two sliders. A second handle is fixedly connected to one side of the sliding baffle.

[0025] In a possible design, a placement groove is opened at the top of the device housing. A display screen and a control panel are arranged inside the placement groove. A limiting rod is fixedly connected to the top of the slider. The top of the limiting rod slidably penetrates through the device housing and extends into the placement groove.

[0026] In a possible design, the same cover plate is rotatably connected between the inner walls on both sides of the placement groove. The cover plate is used to cover the control panel and the display screen. Legs are fixedly connected to the four corners of the bottom of the device housing.

A top block slidably penetrates through the inside of the first round hole. A bottom plate is fixedly connected to the bottom of the top block. The same first tension spring is fixedly connected between the top of the bottom plate and the bottom of the placement table.

[0028] In a possible design, a trapezoidal support block is fixedly connected to one side inner wall of the device housing. The trapezoidal support block is used to support a rotating plate. A second relief groove is formed in one side of the top of the inner rectangular block. The second relief groove is adapted to the trapezoidal support block. Two symmetrically arranged second tension springs are fixedly connected between the bottom of the trapezoidal support block and the bottom inner wall of the second relief groove.

[0029] In this application, when in use, the cover plate is flipped upward to open. At this time, the control panel and the display screen can be exposed, which is convenient for the user to operate the device. The sliding baffle is slid upward vertically through the second handle. At this time, the sliding baffle drives the two sliders to move upward vertically. The sliders compress the spring and drive the limiting rod to move upward. Since the cover plate is opened, the limiting rod will not block at this time, and the sliding baffle can move upward normally, thereby opening the feed port.

[0030] At this time, the sliding baffle no longer blocks the U-shaped plate. At this time, the side plate moves horizontally under the pulling force of the third tension spring. The side plate drives the U-shaped plate to move horizontally. The U-shaped plate drives the internal rotating plate to move horizontally. At this time, the rotating plate extends out of the inside of the feed port. At the same time, since the bottom of the rotating plate gradually abuts against the bottom inner wall of the feed port, the inclined rotating plate can be adjusted to a horizontal state, and the compression spring is compressed. When the rotating plate completely enters the inside of the feed port, the rotating plate cannot be flipped downward.

[0031] At the same time, when the side plate moves horizontally, the side plate no longer blocks the triangular plate at this time, and the braking state of the inner rectangular block is released. Then, the inner rectangular block moves upward under the pulling force of the second tension spring. At the same time, the inner rectangular block drives a plurality of positioning rods to move upward. The positioning rods move out of the inside of the positioning groove. Then, the inner rectangular block can be moved out of the inside of the placement seat, and the braking state of the placement seat can be released.

[0032] At this time, the biological tissue to be broken can be placed on the top of the rotating plate. And since the braking state of the placement seat is released, the placement seat can be pulled out horizontally through the first handle. At this time, the placement hole can be exposed. The collection box is placed inside the placement hole. The placement seat is reset, and the U-shaped plate is pressed back into the inside of the feed port again. The sliding baffle is reset under the elastic force of the spring again to limit the U-shaped plate.

[0033] When the U-shaped plate moves, the inner rectangular block is pressed down again through the triangular plate, and the inner rectangular block drives the positioning rod to move down, and the top of the collection box sinks into the inside of the annular groove, and the placement seat is limited again. When the U-shaped plate is sent in, the rotating plate is turned over under the elastic force of the compression spring, and the tissue on the surface of the rotating plate slides into the inside of the collection box;

[0034] At the same time, the side plate drives the L-shaped rod to move laterally, the L-shaped rod drives the first rack to move laterally, the first rack drives the first gear to rotate, the first gear drives the second rack to move downward, the second rack drives the sliding plate to move downward, the sliding plate drives the multiple crushing knives to move downward, and the downward movement distance of the sliding plate is greater than the downward movement distance of the inner rectangular block. At this time, the crushing knife will extend to the inside of the collection box, the servo motor is started, the output shaft of the servo motor drives the second gear to rotate, the second gear drives the third gear to rotate, the third gear drives the third rotating shaft to rotate, the third rotating shaft drives the multiple crushing knives to rotate, the multiple crushing knives can crush the tissue to achieve the function of crushing the tissue;

[0035] After the crushing is completed, the sliding baffle can be moved up again to release the limit state of the placement seat. When the placement seat is pulled out again, the placement seat moves to the top of the placement table. At this time, the bottom plate will move up under the tension of the first tension spring, and the bottom plate drives the top block to move up. The top block will slightly lift the collection box upward, making it convenient for users to take it.

[0036] Beneficial effects: This equipment realizes automatic feeding and control of biological tissues by setting up structures such as sliding baffles, U-shaped plates, and feeding components. Users can easily add biological tissues and perform subsequent mashing processes through simple operations such as flipping the cover plate and sliding the sliding baffle. This not only simplifies the operation process, but also improves work efficiency.

[0037] The crushing component of this device is driven by a servo motor and crushes the biological tissue through multiple crushing knives. This not only improves the crushing effect, but also reduces tissue waste.

[0038] This device realizes automatic collection and convenient removal of the mashed tissue by setting up a collection box, a placement seat, a limit assembly and other structures. The user only needs to place the collection box in the placement seat, and pull out the placement seat after the mashing is completed, and the mashed tissue can be easily removed. This not only saves the user's operating time, but also ensures the sanitary condition of the tissue.

[0039] All parts of the equipment are made of materials that are easy to clean and disinfect, and the structure is designed reasonably to avoid cross contamination of biological tissues during processing. At the same time, by regularly cleaning and disinfecting the equipment, it can be ensured that the sanitary conditions of the equipment meet the requirements of biomedical research.

At the same time, when the side plate 33 moves horizontally, at this time the side plate 33 no longer blocks the triangular plate 24, and at this time the braking state of the inner rectangular block 25 is released. Then, under the pulling force of the second tension spring 20, the inner rectangular block 25 moves upward. At the same time, the inner rectangular block 25 drives a plurality of positioning rods 29 to move upward. The positioning rods 29 move out of the inside of the positioning groove 28. Then, the inner rectangular block 25 can be moved out of the inside of the placement seat 4, and the braking state of the placement seat 4 can be released;

[0054] An inner rectangular block 25 is slidably connected inside the device housing 1. A limiting component for limiting the collection box 26 is arranged inside the inner rectangular block 25. The limiting component includes two symmetrically arranged positioning rods 29 fixedly connected to the bottom of the inner rectangular block 25. The positioning rods 29 are engaged with the positioning grooves 28. A triangular plate 24 is fixedly connected to one side of the top of the inner rectangular block 25. The triangular plate 24 is used in cooperation with the side plate 33. A second round hole 45 is formed inside the inner rectangular block 25. An arc-shaped hole 46 is formed in the top of the inner rectangular block 25. The arc-shaped hole 46 is communicated with the second round hole 45.

Two symmetrically arranged second tension springs 20 are fixedly connected between the bottom of the trapezoidal support block 21 and the bottom inner wall of the second relief groove 19. At this time, the biological tissue to be broken can be placed on the top of the rotating plate 36. And since the braking state of the placing seat 4 is released, the placing seat 4 can be horizontally pulled out through the first handle 17. At this time, the placing hole 27 can be exposed. The collection box 26 is placed inside the placing hole 27. The placing seat 4 is reset. And the U-shaped plate 32 is pressed back into the feeding port 15 again. The sliding baffle 2 is reset again under the elastic force of the spring 43 to limit the U-shaped plate 32.

[0055] On one side inner wall of the device housing 1, there is a sliding connection with a sliding plate 23. Inside the sliding plate 23, there is a smashing component for smashing biological tissues. The smashing component includes a servo motor 52 fixedly connected to the bottom of the sliding plate 23. The output shaft of the servo motor 52 rotates through the sliding plate 23 and is fixedly connected with a second gear 53. Inside the sliding plate 23, a third rotating shaft 54 rotates through. On the outer wall of the third rotating shaft 54, there is a fixedly sleeved third gear 55 meshing with the second gear 53. On the outer wall of the third rotating shaft 54, there are fixedly sleeved multiple crushing knives 30. When the U-shaped plate 32 moves, at this time, the inner rectangular block 25 is pressed down again through the triangular plate 24. At this time, the inner rectangular block 25 drives the positioning rod 29 to move downward, and the top of the collection box 26 sinks into the internal annular groove 31, and the placement seat 4 is limited again. When the U-shaped plate 32 is sent in, at this time, the rotating plate 36 flips under the elastic force of the compression spring 40. At this time, the tissue on the surface of the rotating plate 36 slides into the internal of the collection box 26.
