[0002] Organoids are multicellular three-dimensional structures with microscopic anatomical features of their source organs, cultured in vitro. 48-well plates are commonly used organoid culture plates in clinical practice; however, due to the small pore size of the wells in 48-well plates, it is difficult to completely remove the organoid droplets cultured in the wells for further experiments.

Detailed Implementation
[0026] The present invention will now be described in detail with reference to the accompanying drawings and specific embodiments. These embodiments are implemented based on the technical solution of the present invention, providing detailed implementation methods and specific operating procedures. However, the scope of protection of the present invention is not limited to the following embodiments.
[0027] Example 1
[0028] To facilitate the complete removal of organoid droplets cultured in the wells of a plate, this embodiment provides an organoid droplet transfer device, see [link to device]. Figure 1-2 It includes a device body 1, a first transfer part, a second transfer part, and an elastic reset member;
[0029] The first transfer part is located at the lower end of the device body 1, and the second transfer part is slidably connected to the device body 1. When the second transfer part abuts against the first transfer part, an organoid droplet transfer cavity is formed. The elastic reset member 2 is located inside the device body 1, with one end connected to the device body 1 and the other end connected to the second transfer part.
[0030] Please see again. Figure 1-2 The first transfer section includes a first arc-shaped segment 6 connected to the lower end of the device body 1 and a first shovel 7 connected to the side of the first arc-shaped segment 6 opposite to the device body 1.
[0031] Please see again. Figure 1-2 The second transfer part includes a sliding seat 3 sleeved on the device body 1, a second arc-shaped segment 5 connected to the lower end of the sliding seat 3, and a second shovel 8 connected to the side of the second arc-shaped segment 5 opposite to the device body 1.
[0032] In this embodiment, grooves are provided on both sides of the first arc-shaped segment 6 and the second arc-shaped segment 5, so that when the first arc-shaped segment 6 and the second arc-shaped segment 5 abut against each other, there is still an area that can be used to observe organoid droplets.
[0033] In this embodiment, the thickness of the side of the first shovel 7 that abuts against the organoid droplet decreases sequentially from the inside to the outside; the thickness of the side of the second shovel 8 that abuts against the organoid droplet also decreases sequentially from the inside to the outside. That is, the first shovel 7 and the second shovel 8 are provided with cutting edges, which can reduce physical damage when cutting into the droplet.
[0034] To facilitate one-handed operation and improve control precision, the sliding seat 3 is provided with a force-applying protrusion 4 on its side. The force-applying protrusion 4 provides a clear force-applying point, which facilitates the sliding seat 3 sliding on the device body 1.
[0035] To enhance operational stability and prevent accidental opening or closing of the transfer cavity due to slippage, anti-slip textures can be provided on the force-applying protrusion 4.
[0036] Please see again. Figure 1 The elastic reset element 2 is a spring, which is inexpensive and easy to replace, while providing a stable reset force.
[0037] Working principle:
[0038] In the initial state, the elastic reset member 2 is in a naturally extended state, pushing the sliding seat 3 of the second transfer part to slide outward, keeping the first spatula 7 and the second spatula 8 separated. When it is necessary to transfer the organoid droplets cultured in the well plate sample loading well, the operator presses the force application protrusion 4 with one thumb to overcome the spring force and make the sliding seat 3 slide inward, causing the second arc-shaped segment 5 to abut against the first arc-shaped segment 6. At this time, the groove area of the two sets of arc-shaped segments forms an observation window, and the cutting edges of the first spatula 7 and the second spatula 8 together form a closed organoid droplet transfer cavity. During the process of the spatula cutting into the culture well, the cutting edge design of the two spatulas, which gradually thins from the inside to the outside, can accurately cut into the bottom of the droplet, effectively reducing shear damage to the droplet structure. After the transfer is completed, the force application protrusion 4 is released, and the elastic reset member 2 automatically resets, causing the transfer cavity to open, thus realizing the precise transfer of organoid droplets.
[0039] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of this utility model without departing from its technical solution shall still fall within the protection scope of this utility model.
