[0037] In this solution, the placenta tissue is first placed in the container bottle 1, the inoculation device is assembled, and then the container bottle 1 is inverted to allow the placenta tissue in the container bottle 1 to enter the grinding shell 2, that is, enter the grinding space; the first blade body 3 and the second blade body 4 rotate relative to each other to achieve the grinding of the placenta tissue, and the size of the grinding particles can be adjusted by the adjustment member 5, thereby achieving the characteristic of controllable size of the ground tissue;

[0038] After grinding is completed, the push rod assembly can push the tissue in the grinding shell 2 into the culture dish 6, thereby reducing contamination of the tissue and improving the success rate of tissue culture.

[0039] The specific structure of the placenta tissue grinding and inoculation device of this embodiment is further described below:

[0040] In this embodiment, a support member 7 is provided at one end of the grinding shell 2 facing the container bottle 1, a support rod 8 is fixed on the support member 7, and the support rod 8 is located in the cavity of the grinding shell 2; the second blade body 4 is provided on the support rod 8, and the first blade body 3 is fixed on the inner wall of the grinding shell 2.

[0041] It is further arranged that the axis of the support rod 8 and the axis of the container bottle 1 are coaxially arranged; wherein the support rod 8 is in the shape of a rectangular parallelepiped, a matching groove is provided on the second blade body 4, and the rectangular parallelepiped is located in the matching groove, so that the inner wall of the matching groove fits the outer wall of the rectangular parallelepiped.

[0042] In this embodiment, a convex ring 9 is provided at the opening of the container bottle 1, and a groove ring 10 is provided on the end of the grinding shell 2 facing the container bottle 1. The convex ring 9 is located in the groove ring 10 and realizes the relative rotation of the container bottle 1 and the grinding shell 2.

[0043] It is further configured that the convex ring 9 on the container bottle 1 can be arranged on the inner wall or outer wall of the container bottle 1, and the corresponding groove ring 10 on the grinding shell 2 can be arranged on the outer wall or inner wall of the grinding shell 2; the axis of the convex ring 9 and the groove ring 10 is also the same as the axis of the container bottle 1.

[0044] To further explain, the selected placenta tissue is cut into blocks and placed in the container bottle 1, the device is inverted, and the operator holds the container bottle 1 with one hand and the grinding shell 2 with the other hand. Through the connection method of the convex ring 9 and the groove ring 10, the grinding shell 2 can be rotated with each other, which prompts the first knife body 3 to rotate, and finally the placenta tissue is ground.

[0045] In this embodiment, a support spring 11 is provided on the support rod 8, and the support spring 11 is located between the support member 7 and the second blade body 4; wherein the second blade body 4 is slidably connected to the support rod 8, and the diameter of the second blade body gradually increases from the container bottle toward the inoculation part;

[0046] A connecting rod 12 is provided on one end of the support rod 8 away from the support member 7 . The adjusting member 5 is a spiral steel knife and is threadedly connected to the connecting rod 12 . The spiral steel knife pushes the second knife body 4 away from or close to the support member 7 .

[0047] Further explanation, during the installation process of the adjusting member 5 (the grinding shell 2 is located above the container bottle 1), the adjusting member 5 moves downward through the thread, causing the adjusting member 5 to approach the container bottle 1. During this process, the supporting spring 11 can abut against the second blade body 4 to cause the second blade body 4 to move stably; since the diameter of the second blade body is different at different positions, the distance between it and the first blade body 3 is also different, and then the distance between the first blade body 3 and the second blade body 4 can be adjusted by the regulator, thereby realizing the adjustment of the size of the grinding tissue. Among them, the distance refers to the distance between the second blade body 4 and the first blade body 3 in the diameter direction.

[0048] In this embodiment, the second blade body 4 includes a first reverse spiral steel blade and a second reverse spiral steel blade.

[0049] Further, the first reverse spiral steel blade and the second reverse spiral steel blade are arranged to realize two grinding processes, so that the grinding is more refined.

Moreover, both ends of the mounting channel 13 are connected. To further explain, the mounting channel 13 and the container bottle 1 are formed as one body.

[0051] The support rod 8 and the connecting rod 12 are both provided with transition passages 14 , and the two transition passages 14 are connected.

[0052] The push rod assembly includes an extrusion housing 15, a fixing member 16, a push spring 17, an extension rod 18 and a push plate 19; the extrusion housing 15 is detachably connected to the outer wall of the bottom surface of the container bottle 1, and the fixing member 16 is arranged on the inner wall of the extrusion housing 15 to increase the hardness and thickness.

The end of the extension rod 18 away from the push spring 17 is provided with a push plate 19, and the push plate 19 is located on the side of the adjustment member 5 away from the second blade 4.

[0053] Further, the extrusion shell 15 is made of rubber material. At this time, pushing the extrusion shell 15 causes the extrusion shell 15 to deform, thereby driving the fixing member 16, the pushing spring 17, and the extension rod 18 to move, and the push rod moves toward the culture dish 6, thereby pushing the ground tissue into the culture dish 6;

[0054] After the pushing is completed, the push spring 17 is pressed against the deformation formed on the outer wall of the container bottle 1 to achieve recovery, and then pushes the extrusion shell 15 in the reverse direction to make the extrusion shell 15 recover.

[0058] It is further provided that the culture dish 6 can be mounted upside down on the second filter 21 by means of a snap-fitting manner.

[0059] To further explain, when the operator rotates the grinding shell 2 for grinding, the inoculation part is located below the grinding shell 2, and the first filter hole 22 and the second filter hole 23 are connected, so that the ground tissue can smoothly enter the culture dish 6; after the grinding is completed, the first filter hole 22 and the second filter hole 23 are staggered, and the inoculation part is inverted to the top of the grinding shell 2. At this time, the tissue pushed into the culture dish 6 by the push plate 19 is placed on the bottom wall of the culture dish 6; then, the second filter 21 is removed from the grinding shell 2, and the culture dish 6 is removed from the second filter 21 by tweezers, and finally the culture dish 6 is placed in the experimental device.

[0060] It is further explained that, during the removal process, the existence of the second filter hole 23 may cause the ground tissue to fall off, so the second filter hole 23 needs to be set as small as possible within a reasonable range.

[0061] In this embodiment, the support member 7 includes an annular sheet 24 and a plurality of support sheets 25, one end of the support sheet 25 is fixed to the inner wall of the grinding shell 2, and the other end of the support sheet 25 is fixed to the annular sheet 24;
