Description

TECHNICAL FIELD

[0001] The utility model relates to an experimental device, in particular to an adjustable human brain tissue thickness sampling board. BACKGROUND

[0002] In the field of neuroscience, pathology and related medical research, precise sectioning of brain tissue is an important step in analyzing the structure and function of specific brain regions. During brain tissue sectioning, two thickness specifications of 0.5 centimeters and 1 centimeter are required for specific regions. Traditional sampling boards are often limited to a single thickness specification, failing to meet the needs of both 0.5 centimeter and 1 centimeter thickness sections. When preparing sections of both 0.5 centimeter and 1 centimeter thickness to study brain region structures at different levels, experimenters have to frequently switch between two different thickness sampling boards. This not only is time-consuming and tedious, but also increases the risk of operational errors, affecting experimental efficiency and section quality. Additionally, for laboratories with limited space, two sampling boards for different thickness specifications occupy valuable space resources, limiting the placement of other experimental equipment and potentially affecting the overall workflow and efficiency of the laboratory.

[0020] As Figures 1-3As shown, the utility model discloses a material taking plate and thickness adjusting plate, the material taking plate includes horizontal quadrilateral bottom plate and the frame of setting on bottom plate, the frame is convenient for taking up material taking plate 1. The frame has three, sets up on the edge of bottom plate 11 respectively, and the edge of bottom plate 11 without frame forms an import and export for the thickness adjusting plate 2 to go in and out. In this embodiment, bottom plate 11 is rectangular bottom plate, three frames are respectively front frame 12 of setting on the upper edge of bottom plate 11, rear frame of setting on the lower edge of bottom plate 11 and left frame 14 of setting on the left edge of bottom plate, and no frame is set on the right edge of bottom plate 11, and in practical application, only need not to set frame on any edge of bottom plate 11, can satisfy the thickness adjusting plate 2 to go in and out demand.

[0021] The cross section of the frame is in the shape of 7, the lower end of the frame is connected with the bottom plate 11, recesses extending outward are arranged on the inner side lower part of the three frames, the lower side of the recess extends to the upper side of the bottom plate 11, the height of the recess is equivalent to the thickness of the thickness adjusting plate 2, and the top wall, the side wall of the frame and the bottom plate 11 form a sliding groove or a slot for the bottom plate to go in and out. When the thickness adjusting plate 2 needs to be inserted or extracted, it can smoothly slide along the recess of the front frame 12 and the rear frame 13, so that the deviation or jamming is avoided, and the convenience and accuracy of operation are improved. The height of the recess is equivalent to the thickness of the thickness adjusting plate 2, which means that when the thickness adjusting plate 2 is completely inserted in place, the bottom of the thickness adjusting plate 2 is stably supported by the bottom of the recess. This not only ensures the stability of the thickness adjusting plate 2 during use, but also prevents shaking or falling caused by external force.

[0022] The heights of the three frames are the same, the distance from the upper edge of the frame to the upper side of the bottom plate is 1cm, and the thickness of the thickness adjusting plate is 0.5cm. When a slice with a thickness of 1cm is needed, the thickness adjusting plate is not used, and the human brain is directly placed on the material taking plate, and the slicing knife is moved along the upper edges of the front frame and the rear frame. When a slice with a thickness of 0.5cm is needed, the thickness adjusting plate is inserted into the sliding groove of the material taking plate, the human brain is placed on the thickness adjusting plate, and the slicing knife is moved along the upper edges of the front frame and the rear frame to slide over the human brain.

[0023] A liquid discharge groove 15 is formed on the frame for liquid outflow, and the liquid discharge groove 15 is formed on the frame opposite to the frame without the frame of the material taking plate 1, so that the problem that liquid is retained on the bottom plate 11 or the thickness adjusting plate 2 of the material taking plate 1 during slicing operation can be solved. In this embodiment, the liquid discharge groove 15 is formed at the junction of the left frame 14 and the rear frame 12. During slicing, due to the characteristics of the material or the need of operation, liquid is inevitably generated and may be retained on the material taking plate 1 or the thickness adjusting plate 2. If the liquid cannot be discharged in time, it may become a disturbing factor, causing unnecessary sliding of the human brain (or other slicing materials) during slicing, thereby seriously affecting the precision and efficiency of the slicing operation.

[0024] Under normal circumstances, most of the liquid will naturally flow to the side of the sampling plate 1 without the frame and be successfully discharged. However, for those liquids far from the side without the frame, the liquid discharge groove 15 on the frame provides another effective discharge channel. This design ensures that no matter where the liquid is located, it can find a fast discharge path, thereby keeping the sampling plate 1 and the thickness adjustment plate 2 clean and dry, creating a stable and reliable environment for slicing operations.
