Description

Technical Field

[0001] This utility model belongs to the field of medical device technology, specifically relating to a pathological slide device for pathology teaching. Background Technology

[0002] In drug experiments, to study the drug components and therapeutic effects of a new drug, small animals are first used. After grouping the animals, animal models are established. Pathological tissue is then cut from the animal models to form tissue blocks, which are then fixed in a fixative. After dehydration, paraffin infiltration, and embedding, the tissue blocks are sectioned. Finally, the sections are observed under a microscope. Pathological tissue sectioning devices are used during this process, and current animal pathological tissue sectioning devices are relatively mature. However, existing teaching sectioning devices mostly use professional laboratory equipment. During the section transfer process, students must use tweezers to handle the sectioned samples, which easily leads to section damage and affects teaching efficiency. Utility Model Content

[0003] In view of the above-mentioned shortcomings in the existing technology, the present invention provides a pathological slide device for pathology teaching, so as to solve the problems in the background technology.

[0004] To solve the above-mentioned technical problems, this utility model adopts the following technical solution: a pathological slide device for pathology teaching, including a body, a sample holder and a moving stage set on the body, a blade mounted on the moving stage, a slide on the moving stage, the slide and the moving stage being detachably connected by a magnetic attraction structure, a folding part on the top of the body, the folding part being rotatably connected to the body, several light strips embedded at the bottom of the folding part, and an openable collection platform at the bottom of the body for receiving slide waste. The magnetically attracted slide allows for one-handed assembly and disassembly and direct transfer, avoiding sample damage caused by tweezers. The folding part with light strips improves the clarity of teaching observation, and the openable collection platform simplifies waste cleaning and improves teaching efficiency.

[0005] Furthermore, the folding angle of the folding part is from 0° to 180°, and the light strip on its inner side illuminates the sample. The folding angle can be flexibly adjusted from 0 to 180°. The light strip directly illuminates the sample, providing a uniform light source and optimizing the visibility of the sample during teaching demonstrations.

[0006] Furthermore, the slide is provided with an upwardly protruding stop, which is located at the lower edge of the upper surface of the slide. The stop at the edge of the slide can prevent the sample from slipping during transfer or slicing, reducing operational errors and sample damage.

[0007] Furthermore, the front side of the collection platform is equipped with a pull-out baffle, which is fixed to the side wall of the collection platform by inserting a block, simplifying the waste cleaning process and shortening the teaching interruption time.

[0008] Furthermore, the moving stage is provided with a limiting block, which is used to limit the lateral displacement of the slide. By constraining the lateral displacement of the slide by the limiting block, the slicing process is stabilized, and the slicing accuracy and sample integrity are improved.

[0009] Furthermore, the mobile platform is equipped with a magnetic component, and the bottom of the carrier plate is equipped with a metal adsorption layer. The magnetic component and the metal adsorption layer provide magnetic attraction, ensuring that the carrier plate is firmly attached and easy to disassemble with one hand, thereby improving the convenience and safety of operation.

[0010] Compared with the prior art, this utility model has the following advantages:

[0011] The magnetic slides can be assembled and disassembled with one hand, allowing for direct transfer of the slides after slicing, avoiding sample damage caused by tweezers. It also features a foldable lighting unit for easy observation by students during teaching. The collection table is designed to be opened, facilitating cleaning and improving teaching efficiency.

Therefore, the terms used to describe positional relationships in the drawings are only for illustrative purposes and should not be construed as limiting this patent. For those skilled in the art, the specific meaning of the above terms can be understood according to the specific circumstances.

[0020] In the description of this utility model, unless otherwise explicitly specified and limited, the term "connection" or similar designation indicating the connection relationship between components should be interpreted broadly. For example, it can refer to a fixed connection, a detachable connection, or an integral part; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium; it can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0021] like Figure 1-3 As shown, this utility model discloses a pathological slide device for pathology teaching, including a body 1, a sample holder 2 and a moving stage 3 mounted on the body 1. A blade 31 is mounted on the moving stage 3, and a slide 32 is provided on the moving stage 3. The slide 32 and the moving stage 3 are detachably connected by a magnetic attraction structure. A folding part 11 is provided on the top of the body 1, and the folding part 11 is rotatably connected to the body 1. Several light strips 112 are embedded at the bottom of the folding part 11. An openable collection platform 4 for receiving slide waste is provided at the bottom of the body 1.

[0022] The folding angle of the folding part 11 is 0 to 180°, and the light strip 112 on its inner side illuminates the carrier sheet 32.

[0023] The carrier sheet 32 ​​is provided with an upwardly protruding stop 321, which is located at the lower edge of the upper surface of the carrier sheet 32.

[0024] The front side of the collection platform 4 is provided with a pull-out baffle 41, which is fixed to the side wall of the collection platform 4 by inserting a block 411.

[0025] The moving platform 3 is equipped with a limiting block 33, which is used to limit the lateral displacement of the carrier piece 32.

[0026] The moving stage 3 is equipped with a magnetic component, and the bottom of the carrier plate 32 is equipped with a metal adsorption layer.

[0027] The working principle of this utility model is as follows: When in use, the pathological tissue to be sliced ​​is fixed on the sample holder 2, and the front and back distance of the moving stage 3 is adjusted to control the slice thickness (this is the prior art). When slicing, the handle on one side of the machine body 1 is rotated, and the sample holder 2 can move up and down (this is the prior art). During the up and down movement of the sample holder 2, the blade 31 scrapes off the pathological tissue, and the sliced ​​pathological tissue falls directly onto the slide 32. The baffle 321 on the slide 32 causes the tissue slice to fall into the collection stage 4. Since the slide 32 is detachably connected to the moving stage 3 through a magnetic structure, it can be removed and transferred directly, avoiding sample damage caused by using tweezers. At the same time, the folding part 11 can rotate around the pin to the required angle, and the light strip 112 at its bottom shines towards the slide 32 to provide a uniform light source to optimize teaching observation. Waste generated during the slicing process falls into the collection stage 4 at the bottom of the machine body 1. When cleaning is required, the collection stage 4 can be opened by pulling out the baffle 41 for cleaning.

[0028] The above are merely embodiments of this utility model.

Those skilled in the art can, under the guidance of this application, improve and implement this solution in conjunction with their own capabilities. Some typical known structures or methods should not be obstacles for those skilled in the art to implement this application. It should be noted that those skilled in the art can make several modifications and improvements without departing from the structure of this utility model.
