Description

Technical Field

[0001] The utility model relates to the technical field of organoids, and in particular to an organoid tissue segmentation device. Background Art

[0002] Organoid tissue refers to tissues with specific functions composed of multiple types of cells, which form different organs, such as heart, liver, lungs, kidneys, etc. These tissues usually have specific structures and morphologies in order to perform their specific physiological functions. By dividing organs or tissues into multiple parts through dividing instruments, their structures and functions can be studied in more detail.

[0003] However, in the prior art, common segmentation instruments cut organoid tissue by rotating and squeezing to break it. This cutting method will cause the cut organoid tissue to be uneven in size and cannot meet research needs. In addition, during the cutting process, the cut tissue is prone to block the cutting port and is difficult to clean. Utility Model Content

[0004] The utility model aims to solve the problems of uneven size of organoid tissue after cutting and difficulty in cleaning in the prior art, and proposes an organoid tissue segmentation instrument.

[0005] In order to achieve the above-mentioned purpose, the utility model adopts the following technical scheme: an organoid tissue segmentation instrument, comprising a tool body and a handle, a guide groove starting from the top of the tool body, and a cutting block is fixedly connected to the bottom of the tool body, a blade is fixedly connected to the inside of the cutting block, a segmentation opening is arranged on the inner side of the blade, a cutting plate is fixedly connected to the bottom of the handle, the bottom end of the cutting plate is fixedly connected to the cutting plate, and the cutting surface of the blade is an inclined surface, which matches the segmentation opening.

[0006] Preferably, grips are fixedly connected to both sides of the top end of the handle, and two extrusion plates are symmetrically fixedly connected to the outer surface of the bottom end of the handle.

[0007] Preferably, mounting holes are provided on both sides of the tool body, and threaded rods are threadedly connected to the inner sides of the mounting holes.

[0008] Preferably, a mounting rod is fixedly connected to the top end of the threaded rod, and a spring is sleeved on the surface of the mounting rod.

[0009] Preferably, the bottom end of the threaded rod passes through the mounting hole, and a nut is threadedly connected to the outer surface of the bottom end of the threaded rod.

[0010] Preferably, a guide block is fixedly connected to the top of the mounting rod, and a guide hole is opened on the surface of the extrusion plate.

[0011] Preferably, the guide hole has a diameter larger than the mounting rod diameter, the bottom end of the spring is fixedly connected to a limit plate, the limit plate is fixedly connected to the outer surface of the mounting rod, and the outer diameter of the limit plate is larger than the mounting hole diameter.

[0012] Compared with the prior art, the advantages and positive effects of the utility model are:

[0013] 1. In the utility model, the tool body, guide groove, tool head and blade not only simplify the placement and cutting steps of organoid tissue, but also greatly improve the efficiency and accuracy of cutting through the precise matching of the dividing port and the tool head. In addition, the design of the tool head also avoids the adhesion of tissue during the cutting process and the clogging of the dividing port, ensuring the neatness of the cutting process and the long-term use of the tool.

[0014] 2. In the utility model, the precise alignment of the guide hole and the guide block, as well as the design of the cone shape, ensures that the cutting process is fast and accurate. At the same time, the compression and recovery of the spring provide smooth and reliable support for cutting, effectively improving the cutting efficiency. After the cutting is completed, the rapid ejection of the cutter head not only improves the separation efficiency, but also enhances the safety of the operation. BRIEF DESCRIPTION OF THE DRAWINGS

[0020] In order to more clearly understand the above-mentioned purpose, features and advantages of the utility model, the utility model is further described below in conjunction with the accompanying drawings and embodiments. It should be noted that the embodiments of the present application and the features in the embodiments can be combined with each other without conflict.

[0021] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways than those described herein. Therefore, the present invention is not limited to the specific embodiments of the following disclosure.

[0022] Embodiment 1

[0023] like Figure 1-4 As shown, the utility model provides an organoid tissue segmentation instrument, including a tool body 1 and a handle 3. A guide groove 11 is provided at the top of the tool body 1, and a cutting block 2 is fixedly connected to the bottom of the tool body 1. A blade 21 is fixedly connected inside the cutting block 2. A segmentation opening 22 is arranged on the inner side of the blade 21. A cutting plate 5 is fixedly connected to the bottom of the handle 3. A cutter head 51 is fixedly connected to the bottom end of the cutting plate 5. The cutter head 51 matches the segmentation opening 22, and the cutting surface of the blade 21 is an inclined surface.

[0024] The specific configuration and functions of this embodiment are described in detail below. First, the organoid tissue is accurately placed on the top of the cutting block 2 through the guidance of the guide groove 11, ensuring that they are neatly arranged above the blade 21. This design not only simplifies the placement steps, but also improves the positioning accuracy of the organoid tissue.

[0025] Next, the cutting plate 5 is smoothly inserted into the guide groove 11 by operating the handle 3. As the cutting plate 5 moves downward, it applies uniform pressure to the organoid tissue on the top of the blade 21. In this process, the sharp edge of the blade 21 quickly cuts the organoid tissue, achieving fast and accurate segmentation.

[0026] The design of the blade 51 perfectly matches the shape of the segmentation opening 22. This not only ensures that the organoid tissue can pass through the segmentation opening 22 smoothly, but also avoids the possible jamming during the cutting process. At the same time, the pushing action of the blade 51 also helps to push out the cut organoid tissue smoothly, facilitating subsequent collection and processing.

[0027] During the cutting process, another important function of the blade 51 is to prevent the organoid tissue from adhering to the surface of the blade 21. Due to the pushing effect of the blade 51, the organoid tissue will be pushed out smoothly during the cutting process, reducing the possibility of adhesion. This not only ensures the neatness of the cutting process, but also improves the service life of the blade.

[0028] Embodiment 2

[0029] like Figure 2-4As shown, grips 31 are fixedly connected to both sides of the top of the handle 3, and two extrusion plates 32 are symmetrically fixedly connected to the outer surface of the bottom end of the handle 3. Mounting holes 12 are provided on both sides of the tool body 1, and threaded rods 42 are threadedly connected to the inner side of the mounting holes 12. The top of the threaded rod 42 is fixedly connected to the mounting rod 4, and a spring 44 is sleeved on the surface of the mounting rod 4. The bottom end of the threaded rod 42 passes through the mounting hole 12, and a nut 41 is threadedly connected to the outer surface of the bottom end of the threaded rod 42. A guide block 43 is fixedly connected to the top of the mounting rod 4, and a guide hole 33 is provided on the surface of the extrusion plate 32. The aperture of the guide hole 33 is larger than the diameter of the mounting rod 4, and the bottom end of the spring 44 is fixedly connected to a limit plate 45, which is fixedly connected to the outer surface of the mounting rod 4, and the outer diameter of the limit plate 45 is larger than the aperture of the mounting hole 12.

[0030] The effect achieved by the entire embodiment is that when cutting the organoid, the presence of the handle 31 enables the operator to control the force more easily and stably. During the cutting process, the guide hole 33 is accurately aligned with the guide block 43. The cone shape of the guide block 43 ensures that the guide hole 33 can be quickly and accurately aligned with it.

[0031] Once the guide hole 33 is aligned with the guide block 43, the pressing plate 32 will slide smoothly on the mounting rod 4 along the guide hole 33. In this process, the pressing plate 32 will press the spring 44 on the surface of the mounting rod 4 to compress it. This compression force not only provides necessary support for subsequent cutting, but also ensures the smooth progress of the cutting process.

[0032] When the cutting is completed, the handle 3 and the cutting plate 5 are released, and the spring 44 begins to return to its original state due to the loss of the pressure of the pressing plate 32. This restoring force quickly pushes the pressing plate 32 and the cutter head 51 connected thereto to pop out from the inside of the splitting opening 22. This not only greatly accelerates the separation of the cutter head 51 from the splitting opening 22, but also ensures the safety of the two during the separation process.

[0033] In addition, the design of the mounting rod 4 also takes into account convenience and practicality. The threaded connection between the threaded rod 42 at the bottom and the mounting hole 12 makes the installation process simple and fast. The addition of the nut 41 further enhances the stability and reliability of the connection. This design makes it easy and quick to disassemble and reinstall the mounting rod 4 when storing or maintaining it.

[0034] The use method and working principle of the device: During the cutting process, the presence of the handle 31 greatly facilitates the operation, making the application of force more convenient and efficient. When cutting, the guide hole 33 is first accurately aligned with the guide block 43, thanks to the cone shape design of the guide block 43, which provides a clear alignment mark for the guide hole 33. As the pushing process proceeds, the extrusion plate 32 slides smoothly on the surface of the mounting rod 4 through the guide hole 33, and at the same time squeezes the spring 44 on the surface of the mounting rod 4, so that the spring 44 is squeezed and compressed.

[0035] When preparing to cut, assemble the organoid tissue to be cut and place it inside the tool body 1. Guided by the guide groove 11, the organoid tissue will be neatly stacked on the top of the cutting block 2, ensuring that they are above the blade 21. Next, use the handle 3 to operate so that the cutting plate 5 is smoothly inserted into the guide groove 11. In this way, the cutting plate 5 will apply a uniform force to the organoid tissue on the top of the blade 21, and the tissue will be quickly cut through the sharp edge of the blade 21. With the cooperation of the cutter head 51, the organoid tissue will be cut into a structure that matches the shape of the dividing port 22, and fall out through the dividing port 22, thereby facilitating subsequent collection and processing.

[0036] The matching of the shape of the blade head 51 and the dividing opening 22 not only ensures that the tissue can pass through smoothly, but also prevents the tissue from adhering to the surface of the blade 21 during the cutting process.

[0037] After the cutting is completed, the handle 3 and the cutting plate 5 are released and the force is no longer applied, so that the spring 44 has room to recover and uses its elastic force to push the pressing plate 32, so that the cutter head 51 is quickly ejected from the inside of the cutting opening 22, accelerating the separation of the cutter head 51 from the cutting opening 22.

[0038] In addition, the installation process of the mounting rod 4 is also carefully designed. The threaded connection between the threaded rod 42 at the bottom and the mounting hole 12 ensures the stability of the installation. The nut 41 can further strengthen this connection, so that the mounting rod 4 can be easily and quickly disassembled when storage or maintenance is required.

[0039] The above description is only a preferred embodiment of the present invention and does not limit the present invention in other forms. Any technician familiar with the profession may use the technical content disclosed above to change or modify it into an equivalent embodiment with equivalent changes and apply it to other fields. However, any simple modification, equivalent change and modification made to the above embodiment based on the technical essence of the present invention without departing from the content of the technical solution of the present invention still falls within the protection scope of the technical solution of the present invention.
