Description

Technical Field

[0001] This utility model relates to the field of animal tissue slicing technology, specifically to an adjustable animal tissue slicing device. Background Technology

[0002] Animal tissue sectioning is a crucial and fundamental procedure in research and teaching across many fields, including biology, medicine, and veterinary medicine. However, traditional methods of animal tissue sectioning have numerous limitations.

[0003] Currently, animal tissue sections are mostly prepared manually. Operators use blades to cut the animal tissue, a method highly susceptible to human error. Because it's difficult for a person's hand to maintain absolute stability, tremors easily occur during cutting, leading to compromised flatness and integrity of the sections, resulting in tissue damage and uneven cut surfaces, severely impacting subsequent observation and analysis.

[0004] Furthermore, manual cutting exhibits significant deviations in controlling the uniformity of section thickness. Differences in operating habits and skills among different operators, and even fluctuations in the condition of the same operator at different times, can lead to inconsistent thicknesses for each cut. This unevenness in thickness negatively impacts the accuracy and reproducibility of experimental results, especially in experiments requiring high precision in section thickness, such as quantitative histological analysis and immunohistochemical studies, where it fails to meet experimental requirements.

[0005] In addition, traditional manual slicing devices usually do not have the function of adjusting the slice thickness. Once the cutting begins, the slice thickness is basically fixed, making it difficult to flexibly adjust the slice thickness according to specific experimental requirements. This greatly limits its application in diverse experimental scenarios. Researchers often need to spend extra time and effort to select slices that meet the thickness requirements, reducing work efficiency.

[0006] Therefore, we propose an adjustable animal tissue slicing device to solve the above problems. Utility Model Content

[0008] (II) Technical Solution: To achieve the above objectives, the present invention provides the following technical solution: an adjustable animal tissue slicing device, comprising a main body shell, a drive module provided on the side wall of the main body shell, a conveying component fixedly connected to the inner side wall of the main body shell, and a transverse groove provided on the conveying component.

[0009] Preferably, the drive module includes a drive motor and a belt. One end of the belt in the drive module is fitted with a rotating disk, an eccentric column is fixedly connected to the non-axial part of the rotating disk, and a guide block is fixedly connected to the side wall of the conveyor.

[0010] Preferably, a cross-shaped component is slidably connected to the guide block, and a vertical groove is provided on the cross-shaped component.

[0011] Preferably, a connecting column is fixedly connected to the inner sidewall of the cross-shaped component, the connecting column is slidably adapted to the transverse groove, and a driving body is fixedly connected to the end of the connecting column away from the cross-shaped component, and detection and stabilization grooves are equidistantly opened on the driving body.

[0012] Preferably, a support member is fixedly connected to one end of the bottom of the driving body, an inclined transfer member is fixedly connected to the bottom of the inner cavity of the support member, a transfer port is opened on the support member, and an infrared sensor is fixedly connected to the inner wall of the support member.

[0013] Preferably, an auxiliary strip is fixedly connected to the conveyor, an electrically controlled telescopic component is fixedly connected to the auxiliary strip, and a slitting blade is fixedly connected to the bottom end of the electrically controlled telescopic component.

[0014] (III) Beneficial Effects: Compared with the prior art, this utility model provides an adjustable animal tissue slicing device, which has the following beneficial effects:

[0015] 1. Through its overall design and automated cutting mechanism, this utility model improves the precision and uniformity of slicing, effectively avoiding the uneven slice thickness caused by human factors such as hand tremors and uneven force during manual operation. It can precisely control the thickness of each cut, ensuring the consistency of slice thickness, and providing a highly reliable and reproducible data basis for subsequent histological analysis, pathological diagnosis, and cell biology research. This improves the accuracy and reliability of experimental results, reduces experimental errors caused by differences in slice thickness, and helps researchers more accurately reveal the microstructure and pathological changes of tissue cells.

[0016] Meanwhile, the adjustable cutting thickness further enhances the device's practicality and adaptability. Researchers can flexibly adjust the slice thickness according to different experimental purposes and tissue types to meet diverse scientific research and clinical needs, achieving clear presentation of tissue structures at different levels, thus broadening the device's application scope and improving its versatility in various histological research scenarios.

[0017] 2. This utility model, by adding a detection stabilization groove on the tractor, can be used as a detection mechanism after the thickness of an adjustable animal tissue section has been adjusted. If, after adjustment, the two ends of the slitting blade cannot fall into the detection stabilization groove during trial operation, it indicates that there is an error in the accuracy of the adjustment, and readjustment is required. This detection mechanism improves accuracy by ensuring that the adjusted thickness is accurate, laying a solid foundation for precise analysis. From the perspective of enhancing experimental reliability, in long-term projects such as animal tissue section analysis for drug development and basic biological research, it effectively ensures the reproducibility and comparability of experimental results, accelerates the research process, and reduces costs. At the same time, it greatly improves the simplicity of detection operation, allowing operators to quickly detect and implement precise thickness adjustments without complex operations, reducing skill requirements and improving work efficiency and comfort.

[0026] 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.

[0027] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments.

[0028] Example: Please refer to Figures 1 to 6 As shown:

[0029] An adjustable animal tissue slicing device includes a main shell 1, a drive module 2 disposed on the side wall of the main shell 1, a conveyor 3 fixedly connected to the inner side wall of the main shell 1, a transverse groove 4 formed on the conveyor 3, the drive module 2 including a drive motor and a belt, a rotating disk 5 sleeved on one end of the belt in the drive module 2, an eccentric column 6 fixedly connected to the non-axial part of the rotating disk 5, a guide block 7 fixedly connected to the side wall of the conveyor 3, a cross member 8 slidably connected transversely inside the guide block 7, a vertical groove 9 formed on the cross member 8, and a connecting column 10 fixedly connected to the inner side wall of the cross member 8. The sliding adapter is fitted to the transverse groove 4. The end of the connecting column 10 away from the cross part 8 is fixedly connected to the driving body 11. The driving body 11 is provided with detection and stabilization grooves 12 at equal intervals. The bottom end of the driving body 11 is fixedly connected to the support part 13. The bottom of the inner cavity of the support part 13 is fixedly connected to the inclined transfer part 14. The support part 13 is provided with a transfer port 15. The inner wall of the support part 13 is fixedly connected to the infrared sensor 16. The conveying part 3 is fixedly connected to the auxiliary strip. The auxiliary strip of the conveying part 3 is fixedly connected to the electrically controlled telescopic part 17. The bottom end of the electrically controlled telescopic part 17 is fixedly connected to the sliding blade 18.

[0030] in:

[0031] The drive module 2 includes a drive motor and a belt. One end of the belt is connected to the drive motor, and the other end is connected to the rotating disk 5.

[0032] The conveyor 3 is equipped with a conveyor belt to transfer the animal tissue placed inside to the support 13.

[0033] The conveyor 3 has a square groove, which is used to stabilize the inclined transfer member 14 during movement.

[0034] The transverse groove 4 is mainly used for guiding the connecting post 10 on the cross part 8.

[0035] The rotating disk 5 is controlled by a motor.

[0036] The eccentric column 6 and the vertical groove 9 are slidably adapted.

[0037] The detection stabilization groove 12 is used in conjunction with the falling slitting blade 18 to provide side feedback and monitoring of the distance the moving body 11 has moved, i.e. whether the adjusted cutting thickness is accurate.

[0038] The distance between the support 13 and the conveyor 3 determines the thickness of the animal tissue slice; and the support 13 can be replaced with different sizes and models according to the specific animal tissue.

[0039] The transfer port 15 is mainly used in conjunction with the oblique transfer component 14 to transfer the cut animal tissue slices out of the support component 13.

[0040] The infrared sensor 16 is mainly used to detect whether the animal tissue conveyed by the conveyor 3 has moved to its own position, thereby controlling the main controller of the device to instruct the electrically controlled telescopic component 17 to carry the slitting blade 18 to perform cutting work.

[0041] Working principle:

[0042] When using it, you first need to adjust the device according to the specific requirements to match the required animal tissue thickness. Only after the adjustment is completed can you perform animal tissue sectioning.

[0043] Please refer to the attached document. Figure 2 First, the drive module 2 is controlled by the main control of the device, which causes the belt in the drive module 2 to drive the rotating disk 5 to rotate. The rotating disk 5 will move the eccentric column 6 which is not fixed to the axis. When the eccentric column 6 moves around the rotation axis of the rotating disk 5, the eccentric column 6 will move laterally as a whole through the vertical groove 9 opened on the cross part 8 with the cooperation of the guide block 7 on the side wall of the conveyor 3. During the movement, the connecting column 10 on the cross part 8 will move the driving body 11 away from or towards the conveyor 3 under the guidance of the transverse groove 4. The following description is based on the driving body 11 moving away from the conveyor 3.

[0044] For further details, please refer to the appendix. Figure 3 As the driving body 11 moves the support 13 away from the conveyor 3, the inclined transfer member 14 in the support 13 will move along with the support 13. Furthermore, the tail end of the inclined transfer member 14 will move under the guidance of the square groove opened on the conveyor 3.

[0045] Furthermore, after the adjustment is completed, the position needs to be checked. At this time, the main controller controls the electronic telescopic component 17 to slowly extend and retract, thereby moving the slitting blade 18 downward. During the movement, two situations may occur. First, the slitting blade 18 enters the detection and stabilization groove 12 opened on the drive body 11. This indicates that the above adjustment is correct. Otherwise, it needs to be readjusted.

[0046] Furthermore, after adjustment, the animal tissue is placed into the conveyor 3. The animal tissue will be conveyed by the conveyor belt in the conveyor 3 and moved into the support 13 with the assistance of the inclined transfer member 14. When it moves to the position of the infrared sensor 16 in the support 13, the infrared sensor 16 detects its presence and will control the electronic telescopic member 17 to carry the cutting blade 18 to perform the cutting action through the device's main control. The cut tissue will be transferred from the transfer port 15.

[0047] Furthermore, through overall design, and under the premise of automated cutting mechanism, the precision and uniformity of slicing can be improved, effectively avoiding the problem of uneven slice thickness caused by human factors such as hand tremors and uneven force application during manual operation. It can precisely control the thickness of each cut, ensuring the consistency of slice thickness, and providing a highly reliable and reproducible data basis for subsequent histological analysis, pathological diagnosis, and cell biology research. This improves the accuracy and reliability of experimental results, reduces experimental errors caused by differences in slice thickness, and helps researchers more accurately reveal the microstructure and pathological changes of tissue cells.

[0048] Meanwhile, the adjustable cutting thickness further enhances the device's practicality and adaptability. Researchers can flexibly adjust the slice thickness according to different experimental purposes and tissue types to meet diverse scientific research and clinical needs, achieving clear presentation of tissue structures at different levels, thus broadening the device's application scope and improving its versatility in various histological research scenarios.

[0049] Furthermore, by adding a detection stabilization groove 12 to the actuator 11, it can be used as a detection mechanism after the thickness of the adjustable animal tissue section is adjusted. If, after adjustment, the two ends of the slitting blade 18 cannot fall into the detection stabilization groove 12 during the trial run, it indicates that there is an error in the accuracy of the adjustment, and readjustment is required. This detection mechanism improves accuracy by ensuring that the adjusted thickness is accurate, laying a solid foundation for precise analysis. From the perspective of enhancing experimental reliability, in long-term projects such as animal tissue section analysis for drug development and basic biological research, it effectively ensures the reproducibility and comparability of experimental results, accelerates the research process, and reduces costs. At the same time, it greatly improves the simplicity of detection operation, allowing operators to quickly detect and implement precise thickness adjustment without complicated operations, reducing skill requirements and improving work efficiency and comfort.
