[0001] The utility model relates to the technical field of tissue section, especially to an animal tissue section device. BACKGROUND

[0002] In life science experimental research, brain tissue section of experimental animals is an important step for brain morphological structure, physiology and pathology research. In recent years, with the continuous improvement of experimental precision requirement, the precision and convenience of the mold during brain tissue section are put forward higher and higher technical requirements.

[0003] After searching, the existing Chinese patent with publication number CN208171636U provides a rotary unit composite brain section mold, belonging to the field of animal experiment equipment design and manufacture, including mold longitudinal section unit, rotary fixed shaft and rotary adjusting shaft. Each mold longitudinal section unit is higher than the conventional brain section mold on the market, and the upper end is concave downward, and the concave area forms a specimen storage tank after being connected in series. Each section unit is provided with a blade guide groove below the horizontal plane of the lowest specimen, and two round holes are arranged on each blade guide groove for passing through the rotary fixed shaft and the rotary adjusting shaft, and the rotary adjusting shaft can be pulled out according to the scale. The top surfaces of adjacent section units are separated and distinguished by different color layers. The blade guide grooves of the same layer are the same color. The device can effectively reduce the problems of uneven thickness and shape difference of the specimen caused by matching error of the blade guide groove; can save operation time; after sectioning, the mold longitudinal section unit with brain section can be rotated out, reducing the damage to the brain tissue.

[0004] However, in the prior art, when the animal pathological tissue is sectioned, the cutting blade and cutting plate used for cutting cannot be adjusted according to the actual demand of the thickness of the cutting, and only one specification of thickness can be cut, which is inconvenient to use. A scheme is proposed to solve the problems in the above background technology. UTILITY MODEL CONTENTS

[0005] In order to make up for the above shortcomings, the utility model provides an animal tissue section device, which aims to improve the problem that the cutting blade and cutting plate used for cutting cannot be adjusted according to the actual demand of the thickness of the cutting when the animal pathological tissue is sectioned, and only one specification of thickness can be cut, which is inconvenient to use.

[0006] To achieve the above objectives, this utility model adopts the following technical solution: It includes a cutting table, a blade holder above the cutting table, a sliding groove below the blade holder, a mounting bracket evenly and slidably engaged below the sliding groove, a blade fixedly connected to the lower end of the mounting bracket, movable rods fixedly connected to both sides of the mounting bracket, a first slide rail rod fixedly connected to both sides of the blade holder, movable plates on both sides of the blade holder, two sides of one side of each of the two movable plates slidably engaged with one side of each of the four first slide rail rods, movable grooves evenly formed in the middle of the two movable plates, the outer surfaces of the movable rods slidably connected to the interior of the movable grooves, a mounting rod fixedly connected to one side of the upper end of the blade holder, a first electric push rod fixedly connected to one side of the mounting rod, a connecting plate fixedly connected to the output end of the first electric push rod, and both ends of the connecting plate fixedly connected to one side of each of the two movable plates.

The No. 1 electric push rod drives the movable plates on both sides to move up and down. When the movable plates move up, the movable rods on both sides of each mounting bracket will disperse under the action of the movable groove, increasing the distance between each blade to cut animal tissue with a large thickness requirement. Conversely, by moving the movable plates down, the distance between the blades can be shortened to cut animal tissue with a small thickness requirement. In this way, the device can adjust the distance between the blades according to actual needs when slicing animal tissue, so that the device can meet different slicing requirements.

[0008] Preferably, a fixing frame is fixedly connected to the upper end of the cutting table, and a second electric push rod is fixedly connected above the fixing frame.

[0009] As a further description of the above technical solution: the fixing bracket can be used to fix the No. 2 electric push rod on the cutting table.

[0010] Preferably, the output end of the second electric push rod is fixedly connected to the upper end of the tool holder, and the lower end of the cutting table is fixedly connected to the third electric push rod.

[0011] As a further description of the above technical solution: the No. 2 electric push rod can be used to push and pull the knife holder for slicing animal tissue.

[0012] Preferably, the output end of the third electric push rod is fixedly connected to a push block, and the upper end of the push block is slidably connected to the lower end of the cutting table.

[0013] As a further description of the above technical solution: the push block can be moved by the drive of the No. 3 electric push rod.

[0014] Preferably, both sides of the push block are rotatably connected to push-pull rods, and one end of each of the two push-pull rods is rotatably connected to a sliding rod.

[0015] As a further description of the above technical solution: the push-pull rod can move under the push and pull of the push block, which is used to drive the sliding rod to gather or disperse.

[0016] Preferably, the lower end of the cutting table is fixedly connected to a second slide rail rod, and the two sides of the outer surface of the second slide rail rod are slidably connected to the upper part of the two slide rods respectively.

[0017] As a further description of the above technical solution: the second slide rail rod allows the sliding rod to move below it.

[0018] Preferably, a connecting rod is fixedly connected to the top of one end of each of the two sliding rods, and a clamping plate is fixedly connected to one end of each of the two connecting rods.

[0019] As a further description of the above technical solution: the connecting rod can be used to fix the clamping plate and the sliding rod together.

[0020] Preferably, reinforcing ribs are fixedly connected to both sides of the connecting plate, and support rods are fixedly connected to all four sides of the lower end of the cutting table.

[0021] As a further description of the above technical solution: the reinforcing ribs can effectively enhance the structural strength of the connecting plate.

[0022] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0023] 1. In this utility model, when slicing animal tissues requiring different thicknesses, the first electric push rod can be activated. The first electric push rod drives the movable plates on both sides to move up and down. When the movable plates move up, the movable rods on both sides of each mounting bracket will disperse under the action of the movable groove, increasing the distance between each blade to cut animal tissues with larger thickness requirements. Conversely, by moving the movable plates down, the distance between the blades can be shortened to cut animal tissues with smaller thickness requirements. This method allows the device to adjust the distance between the blades according to actual needs when slicing animal tissues, enabling the device to meet different slicing requirements.

[0024] 2. In this utility model, when slicing the positioned tissue, the positioned tissue can be placed above the cutting table first, and then the No. 3 electric push rod can be started. The No. 3 electric push rod pulls the push block to move, causing the push-pull rods on both sides of the push block to shift and pull the sliding rods on both sides to converge. When the sliding rods converge, the connecting rods fixed above them will also converge and push the two clamping plates to converge to clamp the animal tissue. In this way, the device can keep the animal tissue in the center of the cutting table at all times when clamping the animal tissue, making the slicing work more stable and smooth.

[0031] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. 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.

[0032] Reference Figures 1 to 4As shown, one embodiment of this utility model includes a cutting table 1, a blade holder 17 above the cutting table 1, a sliding groove 19 below the blade holder 17, a mounting bracket 18 evenly slidably engaged below the sliding groove 19, a blade 9 fixedly connected to the lower end of the mounting bracket 18, movable rods 15 fixedly connected to both sides of the mounting bracket 18, a first slide rail rod 16 fixedly connected to both sides of the blade holder 17, movable plates 3 on both sides of the blade holder 17, two sides of one side of the two movable plates 3 respectively slidably engaged with one side of the four first slide rail rods 16, movable grooves 14 evenly opened in the middle of the two movable plates 3, the outer surfaces of the movable rods 15 respectively slidably connected to the interior of the movable grooves 14, a mounting rod 6 fixedly connected to one side of the upper end of the blade holder 17, a first electric push rod 5 fixedly connected to one side of the mounting rod 6, a connecting plate 8 fixedly connected to the output end of the first electric push rod 5, and the two ends of the connecting plate 8 respectively fixedly connected to one side of the two movable plates 3.

[0033] In this embodiment, when slicing is required for different thicknesses, the first electric push rod 5 can be activated. The first electric push rod 5 drives the two movable plates 3 on both sides to move upward and downward. When the movable plates 3 move upward, the movable rods 15 on both sides of each mounting bracket 18 will disperse under the action of the movable groove 14, increasing the distance between each blade 9 to cut animal tissue with a large thickness requirement. Conversely, by moving the movable plates 3 downward, the distance between the blades 9 can be shortened to cut animal tissue with a small thickness requirement. In this way, the device can adjust the distance between the blades 9 according to the actual needs when slicing animal tissue, so that the device can meet different slicing requirements.

[0034] Example 2, as Figure 1 and Figure 4 As shown, a fixed frame 2 is fixedly connected to the upper end of the cutting table 1. A second electric push rod 4 is fixedly connected above the fixed frame 2. The output end of the second electric push rod 4 is fixedly connected to the upper end of the tool holder 17. A third electric push rod 12 is fixedly connected to the lower end of the cutting table 1. A push block 20 is fixedly connected to the output end of the third electric push rod 12. The upper end of the push block 20 is slidably connected to the lower end of the cutting table 1. Push-pull rods 21 are rotatably connected to both sides of the push block 20. A sliding rod 7 is rotatably connected to one end of each of the two push-pull rods 21. A second slide rail 22 is fixedly connected to the lower end of the cutting table 1. The two sides of the outer surface of the second slide rail 22 are slidably connected to the upper ends of the two sliding rods 7 respectively. A connecting rod 11 is fixedly connected to the upper end of each of the two sliding rods 7. A clamping plate 10 is fixedly connected to one end of each of the two connecting rods 11. Reinforcing ribs 23 are fixedly connected to both sides of the connecting plate 8. Support rods 13 are fixedly connected to all four sides of the lower end of the cutting table 1.

[0035] In this embodiment, when slicing the positioned tissue, the positioned tissue can be placed above the cutting table 1 first, and then the No. 3 electric push rod 12 is activated. The No. 3 electric push rod 12 pulls the push block 20 to move, causing the push-pull rods 21 on both sides of the push block 20 to shift and pull the sliding rods 7 on both sides to converge. When the sliding rods 7 converge, the connecting rods 11 fixed above them also converge and push the two clamping plates 10 to converge and clamp the animal tissue. In this way, the device can always keep the animal tissue in the center position of the cutting table 1 when clamping the animal tissue, making the slicing work more stable and smooth.

[0036] Working principle: When slicing with different thickness requirements, the first electric push rod 5 is activated. The first electric push rod 5 drives the two movable plates 3 on both sides to move up and down. When the movable plates 3 move up, the movable rods 15 on both sides of each mounting bracket 18 will disperse under the action of the movable groove 14, increasing the distance between each blade 9 for cutting animal tissue with a large thickness requirement. Conversely, by moving the movable plates 3 down, the distance between the blades 9 can be shortened for cutting animal tissue with a small thickness requirement. When slicing the positioning tissue, the positioning tissue can be placed above the cutting table 1 first, and then the third electric push rod 12 is activated. The third electric push rod 12 pulls the push block 20 to move, causing the push-pull rods 21 on both sides of the push block 20 to move and pull the sliding rods 7 on both sides to converge. When the sliding rods 7 converge, the connecting rods 11 fixed above them will also converge and push the two clamping plates 10 to converge and clamp the animal tissue.

[0037] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
