Detailed Implementation

[0024] To make the technical solution, purpose and advantages of this utility model clearer, the following explanation is given in conjunction with the accompanying drawings and embodiments.

[0025] Example 1

[0026] As shown in Figures 1 to 5, the biological tissue slicing device of this utility model includes a base 100 and a slicing slider 4.

[0027] A recessed groove 22 is provided at the rear end of the upper end face of the base 100. A material discharge groove 24 is provided at the front end of the recessed groove 22, which is inclined forward and downward. A blade body 3 is provided on the front side of the base 100 corresponding to the rear groove 22. A cutting edge 31 is provided on the side of the blade body 3 facing the rear groove 22. The cutting edge 31 is flush with or slightly lower than the upper end face of the base 100. In the vertical direction, there is a gap between the height position of the cutting edge 31 and the bottom height position of the rear groove 22, forming a height difference.

[0028] The slicing slider 4 is movably connected to the upper end face of the base 100, and a guide hole 42 for inserting biological tissue is provided at the corresponding position of the rear groove 22.

[0029] When biological tissue is inserted into the feed hole 42, the lower part of the biological tissue falls through the feed hole 42 to the rear groove 22 position under the influence of gravity. By manually pushing the slicing slider 4 from back to front, when it passes the blade body 3, the biological tissue that has fallen into the rear groove 22 position will be cut into slices by the blade body 3. The separated biological tissue slices are then discharged from the feed groove 24 towards the lower side of the base 100.

[0030] In a preferred embodiment, the base 100 is provided with a movable guide groove 11, and the slicing slider 4 is guided and moved along the movable guide groove 11.

[0031] The base 100 includes a blade base 1 and a blade holder 2. The blade base 1 has a horizontally arranged front platform 12, with the blade body 3 positioned behind it. The blade holder 2 has a horizontally arranged rear platform 21, with a recessed rear groove 22 on its upper side. The blade edge 31 is positioned rearward, corresponding to the rear groove 22. The blade base 1 and blade holder 2 are positioned and assembled, so that the front platform 12 and the rear platform 21 are on the same horizontal plane, forming the upper end face of the base 100.

[0032] Specifically, the blade base 1 includes base supports 11 extending on both sides along the front-rear direction to be mounted on both sides of the blade fixing frame 2; two sets of movable guide grooves 11 are provided on the inner side between the two base supports 11, and limiting blocks 41 extend horizontally from both sides of the lower part of the slicing slider 4 and are movably connected to the two movable guide grooves 11. A horizontally arranged front end platform 12 is formed between the two base supports 11, and the rear end position between the two base supports 11 is left open to accommodate the position of the rear end platform 21. A rear groove 22 is provided in the center of the rear end platform 21 corresponding to the open position at the rear end of the base support 11.

[0033] A platform slope 121 is provided on the rear side of the front platform 12. The platform slope 121 is inclined from bottom to top and towards the rear. The blade body 3 is fitted and installed on the platform slope 121 in a sheet shape and is inclined accordingly. An inclined platform contact surface 23 is provided on the front side of the blade holder 2. A material dropping groove 24 is recessed in the center of the platform contact surface 23 corresponding to the front end of the rear groove 22. The platform contact surface 23 and the platform slope 121 are fitted together to position and assemble the blade body 3 between the blade holder 2 and the blade base 1. The blade body 3 and the material dropping groove 24 extend parallel to each other. A circular hole is provided on the blade body 3 corresponding to the position of the material dropping groove 24.

[0034] A front groove 13 is provided on the upper side of the front platform 12, and the rear groove 22 is aligned with the front groove 13 in the front and rear positions and the groove width is adapted accordingly.

[0035] This utility model also includes a counterweight handle 5, which includes a pressing section 51 adapted to the inner diameter of the feed guide hole 42. The counterweight handle 5 includes a gripping section 52 located at the upper part and a pressing section 51 located at the lower part, with the outer diameter of the gripping section 52 being larger than the outer diameter of the pressing section 51. When the pressing section 51 is inserted into the feed guide hole 42, the gripping section 52 is positioned above the slice slider 4.

[0036] With the above-described preferred structural configuration, when performing biological tissue slicing, the biological tissue is first placed into the guide hole 42 through the upper opening of the guide hole 42 of the slicing slider 4. Then, the pressing section 51 of the counterweight handle 5 is inserted into the guide hole 42, and the biological tissue is pressed by the weight of the counterweight handle 5, causing the lower part of the biological tissue to fall into the rear groove 22 of the base 100 through the lower opening of the guide hole 42. Next, the user can hold the holding section 52 of the counterweight handle 5 and push the slicing slider 4 forward along the movable guide groove 11 of the base 100. As the slicing slider 4 moves forward, it is cut by the blade body 3. The cut biological tissue slices are discharged to the lower side of the base 100 through the dropping groove 24 for easy collection and subsequent processing.

[0037] The thickness of the resulting biological tissue section is actually set based on the vertical height difference between the blade 31 on the base 100 and the bottom of the rear groove 22. Based on practical applications, users can select different blade holders 2 with different groove depths in the rear groove 22 to replace the blade base 1, thereby meeting the cutting application requirements for different biological tissue section thicknesses; the groove depth of the rear groove 22 ranges from 0.3 mm to 3 mm.

[0038] Similarly, in order to meet the needs of carrying biological tissue of different sizes, users can select the slide block 4 with different aperture sizes of the guide hole 42 to adapt to the application of base 100 of different specifications, thereby meeting the application needs of biological tissue slides of various sizes.

[0039] Example 2

[0040] Based on Embodiment 1, in this embodiment, the blade base 1 and the blade holder 2 can be integrated into a single base 100. This improves the overall stability of the device, reduces assembly steps, and increases production efficiency. The integrated base 100 can directly machine structures such as the movable guide groove 11, the front platform 12, the rear platform 21, and the rear groove 22, ensuring precision and fit between the various structures before the blade body 3 is inserted. This integrated design is suitable for mass production, reducing production costs and improving product quality.

[0041] In this embodiment, the base 100 is integrated as a whole. To meet the different requirements for the thickness of biological tissue slices, a biological tissue slicing device of a specific specification is processed and customized for users to choose directly, which is more convenient for commercial promotion and sales.

[0042] Example 3

[0043] Building upon embodiments 1 and 2, in this embodiment, the blade body 3 is configured as a replaceable structure that can be detachably mounted to the front platform 12. This allows for the replacement of different types of blades as needed to accommodate different types of biological tissue sectioning requirements. For example, blades with different materials and cutting edge designs can be used for soft tissue and hard tissue, respectively. The replaceable blade structure improves the versatility and flexibility of the device and extends its service life.

[0044] Example 4

[0045] Based on Example 1, in this embodiment, a collection box can be provided on the lower side of the base 100 for collecting the cut biological tissue slices. This facilitates subsequent processing and analysis, improving the practicality of the device. The collection box can be designed as a detachable structure for easy cleaning and replacement. Additionally, a label or marker can be provided inside the collection box to record the source and related information of the slices, facilitating the management and analysis of experimental data.

[0046] Example 5

[0047] Based on Embodiment 1, in this embodiment, the lower end face of the base 100 (blade holder 2) may be provided with anti-slip texture to increase the friction between the device and the operating table and prevent the device from sliding during use. This can improve the stability and safety of the device.

[0048] The biological tissue slicing device of this invention has a simple structure, is easy to operate, produces high-quality slices, and is safe. It can be widely used in biological research and medical diagnosis.

[0049] The above description is only a preferred embodiment of the present utility model.
