[0004] For existing tissue slicing methods, when dealing with fetal monkey tissue, which is a growing tissue, it is necessary to slice and observe the corresponding locations. Therefore, the positioning of the fetal monkey tissue has certain requirements. If the positioning is incorrect, it may be necessary to reposition the fetal monkey tissue. Utility Model Content

[0024] The present application will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0025] This utility model provides a fetal monkey tissue slicing and sampling device, including a receiving frame 1, a three-dimensional needle seat 3 installed on the upper side of the receiving frame 1 for positioning fetal monkey tissue, a support frame 4 slidably connected to the upper side of the three-dimensional needle seat 3, a receiving block 7 fixed at the upper end of the support frame 4, and a connecting ring 9 rotatably connected to the inner side of the receiving block 7, an installation ring 8 installed on the inner side of the connecting ring 9, a limiting seat 14 fixed on the inner side of the installation ring 8, and an installation plate 10 slidably connected to the inner side of the limiting seat 14, and a first cutting blade 11 installed at the lower end of the installation plate 10 for cutting fetal monkey tissue;

[0026] Specifically, after positioning the fetal monkey tissue using the three-dimensional needle holder 3, agar is injected into the hole-like structure on one side of the receiving frame 1 to position the three-dimensional needles in the three-dimensional needle holder 3. The support frame 4 is moved to move the first cutting blade 11 to the position to be cut. Then, the mounting plate 10 is pressed to insert the first cutting blade 11 into the gap between the three-dimensional needles in the three-dimensional needle holder 3, thereby cutting the fetal monkey tissue. Then, the support frame 4 is moved to the corresponding position for slicing.

[0027] When it is difficult to slice the fetal monkey tissue due to poor placement, it may be necessary to remove the agar and reposition the fetal monkey, resulting in waste of raw materials. To address this issue, the rotating connection between the connecting ring 9 and the receiving block 7 can be used to adjust the rotation angle of the first cutting blade 11 by sliding the connecting ring 9. Then, it can be inserted into the gap of the three-dimensional needle in the three-dimensional needle holder 3 to slice the fetal monkey tissue.

[0028] The lower end of the support frame 4 is equipped with a first iron block 5, and a magnetic strip 6 installed in the three-dimensional needle seat 3 is correspondingly provided on the lower side of the first iron block 5. This allows the first iron block 5 to be attracted by the magnetic strip 6 to a certain extent when it moves, thereby increasing the friction of movement. After the support frame 4 moves to the corresponding position, the magnetic force between the first iron block 5 and the magnetic strip 6 is used to position the support frame 4.

[0029] The upper side of the first cutting blade 11 is provided with a second iron block 12 installed on the left and right sides of the mounting plate 10, and the inner side of the mounting ring 8 is provided with a magnetic block 13 corresponding to the second iron block 12. When the mounting plate 10 moves upward, when the second iron block 12 corresponds to the magnetic block 13, the magnetic force between the second iron block 12 and the magnetic block 13 can limit the height of the mounting plate 10 and prevent it from moving downward, thereby preventing the mounting plate 10 from falling freely and affecting the movement of the support frame 4.

[0030] A cover 2 is snapped onto one side of the receiving frame 1, making it easy to remove the cover 2 and thus take out the agar positioned inside the receiving frame 1.

[0031] An adjusting rod 15 is rotatably connected to one side of the upper end of the mounting plate 10, and a limiting rod 16 is slidably connected to the other side of the upper end of the mounting plate 10. A second cutting blade 17 is installed on one side of the mounting plate 10. The second cutting blade 17 is threadedly connected to the adjusting rod 15, and the second cutting blade 17 is slidably connected to the limiting rod 16, so that the distance between the second cutting blade 17 and the first cutting blade 11 can be adjusted, thereby enabling the fetal monkey tissue to be sliced ​​in one go, improving the slicing efficiency.

[0032] The technical features of the above embodiments can be combined in any way (as long as there is no contradiction in the combination of these technical features). For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described; these embodiments not explicitly written should also be considered to be within the scope of this specification.
