Embodiment 1

[0052] figure 1 Is a partial cross-sectional view of the three-dimensional structure of the biological sample dividing machine in the first embodiment of the present invention, figure 2 It is a cross-sectional view of the biological sample dividing machine in the first embodiment of the present invention, such as figure 1 versus figure 2 As shown, the biological sample dividing machine 100 of the first embodiment of the present invention includes a dividing net 110, a rotating stage 120, a rotating driving device 130, a collector 140, an air jet 150, and a liquid jet 160. The dividing net body 110 surrounds an accommodating space 111, and a first opening 112 and a second opening 113 located on two opposite sides of the accommodating space 111 and communicating with the accommodating space 111. In the first embodiment of the present invention, the dividing net body 110 is a hollow columnar structure with two openings, but it is not limited to this. In other embodiments of the p...

Embodiment 2

[0064] image 3 Is a cross-sectional view of the biological sample dividing machine in the second embodiment of the present invention, such as image 3 As shown, the second embodiment of the present invention is similar to the first embodiment, and only the differences are described below, and the similarities are not repeated here.

[0065] In the biological sample dividing machine 200 of the second embodiment of the present invention, the bearing surface 221 of the rotating stage 220 has a plurality of protruding structures 2211. The plurality of protruding structures 2211 can increase the frictional force between the biological sample S and the bearing surface 221, and prolong the time that the biological sample S rotates with the bearing surface 221, so that the biological sample S bears greater centrifugal force when it is separated from the bearing surface 221 and has Greater speed. In this way, a better cutting effect can be obtained when the biological sample S hits the d...

Embodiment 3

[0067] Figure 4 Is a cross-sectional view of the biological sample dividing machine in the third embodiment of the present invention, such as Figure 4 As shown, the third embodiment of the present invention is similar to the first embodiment, and only the differences are described below, and the similarities are not repeated here.

[0068] In the biological sample dividing machine 300 of the third embodiment of the present invention, the thickness of the center area of ​​the rotating stage 320 is smaller than the thickness of the edge area, so that the bearing surface 321 is disk-shaped. The disc-shaped bearing surface 321 makes the centrifugal force only the component of the centrifugal force directed from the center area of ​​the rotating stage 320 to the edge area to drive the biological sample S to move away from the bearing surface, extending the time for the biological sample S to rotate with the bearing surface 321 Therefore, the biological sample S has a greater speed ...

Abstract

A biological sample divider and a biological sample dividing method are provided. The biological sample divider includes a dividing mesh and a rotating platform. The dividing mesh surrounds an accommodating space. The rotating platform is rotatable relative to the dividing mesh and disposed in the accommodating space. The rotating platform has a bearing surface for bearing at least one biological sample. When the rotating platform rotates relative to the dividing mesh, the rotating platform throws the biological sample toward the dividing mesh so that the dividing mesh divides the biological sample into a plurality of fragments.

Description

Technical field [0001] The invention relates to the field of machinery, in particular to an automatic biological sample segmentation machine and an automatic biological sample segmentation method. Background technique [0002] With the rapid development of biotechnology, various tissue culture and biological detection technologies and analysis equipment allow researchers to explore the mysteries of biology in more depth. After the researcher obtains the biological sample, in order to carry out different test items or tissue culture, the obtained original biological sample needs to be divided into smaller biological samples, and then the smaller biological samples are placed in the analysis equipment for analysis , Or put it in a petri dish or a culture tank for tissue culture. [0003] Currently, the biological sample segmentation method in the known technology is that the researcher first fixes the biological sample with one hand, and then directly separates the biological sample...
