Description

Technical Field

[0001] This invention belongs to the field of cell component slicing technology, specifically relating to a cell tissue slicing mechanism. Background Technology

[0002] In many fields such as biomedical research, clinical diagnosis, and drug development, cell tissue sectioning technology is a crucial foundational technology. By precisely sectioning cell tissues, researchers can observe the structure, morphology, and microscopic features of cells and tissues in depth, thus providing key evidence for disease diagnosis, treatment planning, and the study of biological mechanisms.

[0003] Currently, there are various types of cell and tissue sectioning institutions on the market, which to some extent meet the needs of different application scenarios; however, with the continuous deepening of biomedical research and the increasing demands of clinical testing, existing cell and tissue sectioning institutions have gradually exposed some problems that urgently need to be solved.

[0004] First, since cell tissues are usually encased in wax blocks, the wax blocks need to be reshaped and adjusted into rectangles or trapezoids before slicing to ensure that the slices are uniform and complete. However, this operation is currently still done manually, which is time-consuming and cannot improve work efficiency. Second, currently available patented technologies and cell tissue slicers can only perform simple slicing operations and do not have automated and continuous operation of reshaping and slicing. Utility Model Content

[0005] The purpose of this utility model is to provide a cell tissue slicing mechanism to solve the problems in the existing technology, where the operation steps are still based on manual operation, the whole process is time-consuming and cannot improve work efficiency; secondly, the currently disclosed patented technical solutions and cell tissue slicer products can only perform simple slicing operations and do not have the technical defects of automated and continuous operation of shaping and slicing.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A cell tissue slicing apparatus, comprising:

[0008] The base has a receiving cavity.

[0009] The clamping device, the shaping device, and the slicing device are all disposed in the receiving cavity, and the clamping device, the shaping device, and the slicing device are disposed at intervals, with the shaping device and the slicing device located above the clamping device.

[0010] A control device is disposed on the outside of the base, and the control device is electrically connected to the clamping device, the shaping device and the slicing device;

[0011] The clamping device is used to clamp and fix the cell tissue to be sliced;

[0012] The shaping device is used to shape the cell tissue to be sliced;

[0013] The slicing device is used to slice the modified cell tissue.

[0014] Furthermore, the clamping device includes a support base and a clamping assembly. The support base is disposed on one side of the clamping assembly, and the support base has a built-in detection unit that is signal-connected to the clamping assembly.

[0015] In this process, after the detection unit detects that the cell tissue to be sliced ​​is placed on the support base, the clamping assembly clamps and fixes the cell tissue to be sliced ​​on the support base.

[0016] Furthermore, the clamping assembly includes a connecting rod, one end of which is connected to a clamping motor, and the other end of which is connected to a clamping rod;

[0017] The clamping rods are provided in two, with a gap between them, and are located at one end and the other end of the support base.

[0018] Furthermore, the clamping rod has an arc-shaped cross-section.

[0019] Furthermore, the shaping device includes a support rod, one end of which is fixed to the bottom surface of the receiving cavity, and the other end is located above the clamping device;

[0020] The support rod is provided with a first drive unit at the top of one end above the clamping device. The drive end of the first drive unit is connected to a hanging rod, and the end of the hanging rod is connected to a support plate.

[0021] The bottom of the support plate is provided with a second drive unit, the drive end of the second drive unit is provided with a support plate, the support plate is equipped with a third drive unit and a shaping tool, the end of the third drive unit is provided with a scraper, and the shaping tool is located above the scraper.

[0022] Furthermore, the shaping tool is a frame-shaped tool.

[0023] Furthermore, the slicing device includes a guide rod, on which a support platform is slidably connected. A fourth drive unit is provided on the top of the support platform, and a slicing blade is connected to the drive end of the fourth drive unit.

[0024] The bottom of the support platform is connected to a fifth drive unit.

[0025] Furthermore, the guide rod has graduations on its outer side.

[0026] Furthermore, the fourth drive unit is axially perpendicular to the guide rod.

[0027] Furthermore, the control device is equipped with a start switch and a drive switch, and there are multiple drive switches, which are used to control the clamping device, the shaping device and the slicing device respectively.

[0028] Compared with the prior art, the present invention has the following beneficial effects:

[0029] 1. Through the coordinated operation of clamping, shaping, slicing, and control devices, automated and continuous shaping and slicing operations are achieved. During the operation, the clamping device first clamps and fixes the cell tissue to be sliced, then the shaping device shapes the cell tissue, and after shaping, the slicing device immediately slices the shaped cell tissue. The coordinated work of each device throughout the process ensures the continuity and accuracy of shaping and slicing operations, improves the quality and consistency of the slices, and provides more reliable samples for biomedical research and clinical diagnosis.

[0030] 2. Since the detection unit is connected to the clamping component by signal, the clamping action will only be triggered after the cell tissue is detected to be in place, thus avoiding the problem of inaccurate clamping caused by human error or untimely operation.

[0031] 3. In the clamping assembly, one end of the connecting rod is connected to the clamping motor, and the other end is connected to the clamping rod, realizing the effective transmission of power. The power generated by the clamping motor is directly applied to the clamping rod through the connecting rod, enabling the clamping rod to respond quickly to the motor's action, thereby efficiently completing the clamping and releasing operations.

[0032] 4. The shape of the wax block is often irregular. The clamping bar with an arc cross-section can better fit the surface of the wax block. Compared with the clamping bar with a straight cross-section, the arc design can form a larger contact area with the wax block during the clamping process. Regardless of whether the cell tissue is round, elliptical or other irregular shape, it can improve the stability and reliability of clamping.

[0033] 5. One end of the support rod is fixed to the bottom surface of the receiving cavity, providing a stable support foundation for the entire shaping device. This allows the shaping device to withstand greater forces and vibrations during operation, ensuring the stability and reliability of the device. Even when large cutting forces are generated during the shaping process, the support rod ensures that the shaping device will not shake or shift, thus guaranteeing the accuracy of the shaping operation.

[0040] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. The components of the embodiments of this utility model described and shown in the accompanying drawings can generally be arranged and designed in various different configurations.

[0045] In many fields such as biomedical research, clinical diagnosis, and drug development, cell tissue sectioning technology is a crucial foundational technology. By precisely sectioning cell tissues, researchers can observe the structure, morphology, and microscopic features of cells and tissues in depth, thus providing key evidence for disease diagnosis, treatment planning, and the study of biological mechanisms.

[0046] Currently, there are various types of cell and tissue sectioning institutions on the market, which to some extent meet the needs of different application scenarios; however, with the continuous deepening of biomedical research and the increasing demands of clinical testing, existing cell and tissue sectioning institutions have gradually exposed some problems that urgently need to be solved.

[0047] First, since cell tissues are usually encased in wax blocks, the wax blocks need to be reshaped and adjusted into rectangles or trapezoids before slicing to ensure that the slices are uniform and complete. However, this operation is currently still done manually, which is time-consuming and cannot improve work efficiency. Second, currently available patented technologies and cell tissue slicers can only perform simple slicing operations and do not have automated and continuous operation of reshaping and slicing.

[0048] In order to overcome the above-mentioned technical defects, the inventors have provided a cell tissue slicing mechanism.

[0049] The present invention will now be described in further detail with reference to the accompanying drawings:

[0050] like Figures 1-4 As shown in the embodiment of this utility model, a cell tissue slicing mechanism is provided, including: a base 1, which is a rectangular structure with a receiving cavity 103 on it, and legs 101 around the bottom of the receiving cavity 103; a clamping device 2, a shaping device 3, and a slicing device 4, all disposed in the receiving cavity 103, with the clamping device 2, the shaping device 3, and the slicing device 4 spaced apart, and the shaping device 3 and the slicing device 4 located above the clamping device 3; and a control device 102 disposed on the outside of the base 1, and electrically connected to the clamping device 2, the shaping device 3, and the slicing device 4; wherein, the clamping device 2 is used to clamp and fix the cell tissue to be sliced; the shaping device 3 is used to shape the cell tissue to be sliced; and the slicing device 4 is used to slice the shaped cell tissue.

[0051] In application, the clamping device 2, the shaping device 3, the slicing device 4, and the control device 102 work together to achieve automated and continuous operation of shaping and slicing. During the operation, the clamping device 2 first clamps and fixes the cell tissue to be sliced, then the shaping device 3 shapes the cell tissue, and after the shaping is completed, the slicing device 4 immediately slices the shaped cell tissue. The various devices work together in the whole process to ensure the continuity and accuracy of the shaping and slicing operations, improve the quality and consistency of the slices, and provide more reliable samples for biomedical research and clinical diagnosis.

[0052] Furthermore, as shown in the figure, the clamping device 2 includes a support base 201 and a clamping assembly. The support base 201 is disposed on one side of the clamping assembly, and a detection unit 202 is built into the support base 201. The detection unit 202 is signal-connected to the clamping assembly. Specifically, in one embodiment, the detection unit 202 is a distance sensor. When a distance sensor is used for detection, a preset sensor detection distance can be set. When the cell tissue to be sliced ​​is placed on the support base 201, if the detected distance between the cell assembly and the ground is less than the preset distance, a signal is transmitted to the clamping assembly to clamp the tissue. It performs clamping and fixing; in another embodiment, the detection unit 202 is an infrared sensor. When using an infrared sensor, as long as the cell tissue blocks the infrared sensor's rays, the infrared sensor can transmit signals to the clamping assembly; it is worth noting that the cell tissue to be sliced ​​is placed on the support base 201 manually by the operator; after the detection unit 202 detects that the cell tissue to be sliced ​​is placed on the support base 201, the clamping assembly clamps and fixes the cell tissue to be sliced ​​on the support base 201, which can ensure that the shaping operation can be reliably carried out in the subsequent shaping process.

[0053] Furthermore, the clamping assembly includes a connecting rod 203, one end of which is connected to a clamping motor 205, and the other end is connected to a clamping rod 204. Two clamping rods 204 are provided, spaced apart, and located at one end and the other end of the support base 201. In operation, a rotating hole is provided on one side of the receiving cavity 103. One end of the clamping rod 204 is rotatably connected to the rotating hole, and the other end is connected to the clamping motor 205. Driven by the clamping motor 205, the two clamping rods 204 can rotate smoothly. Simultaneously, since the two clamping rods 204 are located at one end and the other end of the support base 201, this ensures that the cells to be sliced ​​are firmly fixed to the maximum extent, preventing shaking during shaping.

[0054] The clamping rod 204 has an arc-shaped cross-section. Since cell tissues are often irregularly shaped, the arc-shaped cross-section of the clamping rod 204 allows for better contact with the cell tissue surface. Compared to a straight cross-section clamping rod 204, the arc design creates a larger contact area with the cell tissue during clamping. Regardless of whether the cell tissue is round, elliptical, or has other irregular shapes, it can more tightly enclose the cell tissue, thus improving the stability and reliability of the clamping. A straight cross-section clamping rod 204 may generate excessive pressure locally on the cell tissue during clamping, causing compression and deformation. The arc-shaped cross-section of the clamping rod 204 distributes the clamping force more evenly across the cell tissue surface, avoiding excessive local pressure that could damage the cell tissue. This helps maintain the integrity and original morphology of the cell tissue, providing a higher-quality sample for subsequent shaping and slicing operations.

[0055] In this embodiment, the shaping device 3 includes a support rod 301. One end of the support rod 301 is fixed to the bottom surface of the receiving cavity 103, and the other end is located above the clamping device 2. A first driving unit 302 is provided at the top of the end of the support rod 301 above the clamping device 2. The driving end of the first driving unit 302 is connected to a hanging rod 303, and the end of the hanging rod 303 is connected to a support plate 304. A second driving unit 305 is provided at the bottom of the support plate 304. A bearing plate 306 is provided on the driving end of the second driving unit 305. A third driving unit 308 and a shaping tool 307 are installed on the bearing plate 306. A scraper 309 is provided at the end of the third driving unit 308, and the shaping tool 307 is located above the scraper 309. Specifically, the first drive unit 302, the second drive unit 305, and the third drive unit 308 all use linear motors for operation. As shown in the figure, after the clamping device 2 fixes the cell tissue to be sliced, the first drive unit 302 drives the lifting rod 303 to descend through the control device 102. During the descent of the lifting rod 303, the support plate 304 is driven to descend, and the support plate 304 then drives the second drive unit 305 to descend, which in turn drives the carrier plate 306 to descend. At this time, it is worth noting that the second drive unit 305 can continue to descend so that the shaping tool 307 lands on the surface of the cell tissue to be sliced, subject to the combined action of the second drive unit 305 and the first drive unit 308. The dual driving force of the 2 can directly cut the cell tissue to be sectioned into a frame-shaped structure, ensuring the smooth progress of subsequent sectioning. Since the shaping tool 307 is located between the two clamping rods 204, the shaping operation can be carried out smoothly. Secondly, after the shaping is completed, if the top of the frame-shaped cell tissue is uneven, the operator can visually observe that the second driving unit 305 and the first driving unit 302 can be lowered, and then the third driving unit 308 can be positioned on one side of the frame-shaped cell tissue. Subsequently, the operator manually operates the control device 102 to make the third driving unit 308 drive the scraper 309 to perform a linear reciprocating motion to the other side of the frame-shaped cell tissue to flatten the top of the frame-shaped cell tissue.

[0056] Furthermore, as shown in the figure, the slicing device 4 includes a guide rod 401, on which a support platform 402 is slidably connected. A fourth drive unit 403 is located at the top of the support platform 402, and a slicing blade 404 is connected to the drive end of the fourth drive unit 403. A fifth drive unit 405 is connected to the bottom of the support platform 402. A scale is provided on the outer side of the guide rod 401, and the fourth drive unit 403 and the guide rod 401 are axially perpendicular. After the shaping is completed, the operator operates the control device 102 to activate the fifth drive unit 405, while simultaneously visually observing the position of the slicing blade 404 through the scale, thereby enabling the slicing blade 404 to cut slices of the required thickness.

[0057] In order to accurately control all the drive units, the control device 102 is equipped with a start switch and a drive switch. There are multiple drive switches, which are used to control the drive units in the clamping device 2, the shaping device 3 and the slicing device 4 respectively. When the drive unit corresponding to the drive switch is pressed and held, the drive unit will be driven continuously. When the drive unit corresponding to the drive switch is pressed briefly, the drive unit will move briefly. This control setting can ensure that the thickness of the slice meets the operation requirements.

[0058] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and not to limit its protection scope. Although the utility model has been described in detail with reference to the above embodiments, those skilled in the art should understand that after reading this utility model, they can still make various changes, modifications or equivalent substitutions to the specific implementation of the utility model, but these changes, modifications or equivalent substitutions are all within the protection scope of the pending claims of the utility model.
