[0018] 1. This fully automatic tissue section preparation machine uses a drive assembly to push a tray, which advances the specimen to contact the insert plate. After the insert plate contacts the specimen, part of the specimen's tissue is embedded in the insertion groove. An electric push rod drives the section pusher to cut the specimen inserted into the insertion groove, so that the tissue stays at the top of the section pusher. Since the section pusher is arc-shaped, it can push the cut tissue upward. The upper guide ring pushes the tissue upward to contact the glass slide, which is then manually removed, thus achieving the purpose of automatic section preparation.

[0019] 2. This fully automatic tissue sectioning machine features an arc-shaped cutting edge design on the sectioning pusher, which allows it to smoothly push the tissue upwards during cutting. The cutting edge fits snugly against the bottom surface of the slide mounting groove to ensure cutting accuracy. The machine is driven by an electric pusher to achieve precise sectioning action. In conjunction with the arc-shaped upper guide ring and the sectioning pusher, the cut tissue is further guided to the surface of the slide.

[0026] The present invention will be further described in detail below with reference to the accompanying drawings.

[0027] Example:

[0028] Reference Figure 1 - Figure 4 This utility model discloses a fully automatic tissue section preparation machine, comprising:

[0029] The base 1 has four uprights 2 at its top corners, and a top frame 3 is mounted on the top of each upright 2. The base 1, uprights 2, and top frame 3 together form a three-dimensional square frame structure. Two guide rails 4 are provided at the bottom of the top frame 3. A transverse rod 5 is mounted on these two symmetrically arranged guide rails 4. A control component 6 controls the movement of the transverse rod 5 along the guide rails 4, and a slicing component 8 controls the movement of the slicing slider 7 to facilitate sample extraction from different surfaces of the subject. The transverse rod 5 is slidably mounted on the two guide rails 4. Control components 6 are located at the corners of the top frame 3 to drive the movement of the transverse rod 5. Specifically, when the transverse rod 5 is driven to move by the control component 6, the movement is controlled by... The drive motor 62 drives the control screw 63 to rotate. Since the control screw 63 is threadedly engaged with the transverse rod 5, the transverse rod 5 can be effectively driven to slide laterally during the rotation of the control screw 63. The transverse rod 5 has a sliding slider 7 inside, and a slicing assembly 8 for controlling the movement of the slicing slider 7 is provided at the end of the transverse rod 5. Specifically, when the slicing slider 7 is moved by controlling the slicing assembly 8, the positioning screw 82 is rotated by the servo motor set inside the connecting frame 81. Since the positioning screw 82 is threadedly engaged with the screw hole 83 opened inside the slicing slider 7, the rotation of the positioning screw 82 can achieve the purpose of driving the slicing slider 7 to move.

[0030] In summary, the movement of the slice slider 7 on the plane can be effectively controlled by the control component 6 and the slicing component 8.

[0031] The slide slide slider 7 has an insert plate 9 at its bottom end, and a slide mounting groove 10 is provided inside the insert plate 9. An electric suction cup 11 is provided at the top of the slide mounting groove 10 to hold the tissue slide. An embedding groove 12 is provided at the bottom end of the insert plate 9, and a slide pusher 13 is provided at the bottom of the slide mounting groove 10. By using the insert plate 9, as the slide slide slider 7 moves, the insert plate 9 is moved to different positions above the subject, and at this time, the slide is inserted into the slide mounting groove 10 and fixed by the electric suction cup 11. Then, the drive assembly 15... Push the tray 14 to advance the specimen to contact the insert plate 9. After the insert plate 9 contacts the specimen, part of the specimen's tissue will be embedded in the embedding groove 12. The electric push rod 131 pushes the slide pusher 13 to move and cut the specimen inserted into the embedding groove 12, so that the tissue stays at the top of the slide pusher 13. Since the slide pusher 13 is arc-shaped, it can push the cut tissue upward and push the tissue upward through the upper guide ring 132 so that it contacts the glass slide. Then the glass slide is removed manually, thereby achieving the purpose of automatic slide preparation.

[0032] A support plate 14 is provided on the top of the base 1, and drive components 15 are provided on both sides of the support plate 14 for driving the support plate 14 to move up and down. The drive components 15 include a lifting motor and a lifting screw. The lifting screw is fixedly connected to the motor shaft of the lifting motor, and the lifting screw is threadedly engaged with the support plate 14. Therefore, when the lifting motor rotates, it can control the support plate 14 to move up and down. Guide rods are provided on both sides of the base 1 that pass through the support plate 14 and are slidably connected to the support plate 14.

[0033] In this embodiment, the guide rail 4 system is integrated through a square frame structure. The drive motor 62 of the control component 6 drives the control screw 63 to rotate, so that the horizontal rod 5 moves horizontally along the guide rail 4. At the same time, the slicing component 8 achieves precise longitudinal positioning of the slicing slider 7 by driving the positioning screw 82 through the servo motor, thus forming two-dimensional planar motion control.

[0034] During the slicing process, after the insertion groove 12 at the bottom of the insert plate 9 comes into contact with the subject, the electric push rod 131 drives the arc-shaped slicing pusher 13 to cut the tissue. Combined with the upper guide ring 132, the tissue is pushed to the surface of the glass slide fixed by the electric suction cup 11. The support plate 14 adjusts the height of the subject through the lifting motor and screw mechanism, and finally realizes the fully automated process from positioning, slicing to sample transfer.

[0035] In a further preferred embodiment of this utility model, such as Figure 4 As shown, the bottom surface of the slicing pusher 13 is in contact with the bottom surface of the slide mounting groove 10, and the blade of the slicing pusher 13 is arc-shaped, with the cutting edge in contact with the bottom surface of the slide mounting groove 10.

[0036] In this embodiment, the arc-shaped cutting edge design of the slicing pusher 13 allows it to push the tissue upward during cutting. The cutting edge fits against the bottom surface of the slide mounting groove 10 to ensure cutting accuracy. The precise slicing action is achieved by driving the electric push rod 131.

[0037] In a further preferred embodiment of this utility model, such as Figure 4 As shown, the end of the slicing pusher 13 is provided with an electric push rod 131 for pushing the slicing pusher 13 to move, and the top of the slicing pusher 13 is provided with an upper guide ring 132, which is arc-shaped.

[0038] In this embodiment, the arc-shaped upper guide ring 132 is linked with the slide pusher 13 to further guide the cut tissue to the surface of the glass slide. Its arc design reduces tissue residue and improves the adhesion efficiency of the slide.

[0039] In a further preferred embodiment of this utility model, such as Figure 2 As shown, a lifting platform 16 is provided at the upper end of the pallet 14, and an anti-slip groove is provided on the upper surface of the lifting platform 16.

[0040] In this embodiment, the lifting platform 16 on the tray 14 fixes the specimen through the anti-slip groove, and the lifting screw structure of the drive assembly 15 achieves stable vertical displacement, ensuring uniform contact pressure between the tissue and the insertion plate 9.

[0041] In a further preferred embodiment of this utility model, such as Figure 2 As shown, the control component 6 includes:

[0042] A fixed bracket 61 is fixedly connected to the bottom end of the top frame 3. A drive motor 62 is installed inside the fixed bracket 61. A control screw 63 is fixedly installed at the shaft of the drive motor 62. The control screw 63 passes through one end of the transverse rod 5 and is threadedly engaged with the transverse rod 5.

[0043] In this embodiment, a drive motor 62 is used to drive the control screw 63 to rotate. The rotational motion is converted into linear movement of the transverse rod 5 by utilizing the thread engagement principle, thereby achieving horizontal adjustment of the slice position.

[0044] In a further preferred embodiment of this utility model, such as Figure 3 As shown, the slicing component 8 includes:

[0045] Two connecting frames 81 are fixedly installed at both ends of the horizontal rod 5. A positioning screw 82 is provided between the two connecting frames 81, and a screw hole 83 that cooperates with the positioning screw 82 is opened inside the slicing slider 7.

[0046] In this embodiment, the positioning screw 82 is driven to rotate by a servo motor, so that the slice slider 7 moves along the screw hole 83 inside the transverse rod 5 to complete precise longitudinal positioning and form a two-dimensional planar motion control system.

[0047] The embodiments described herein are preferred embodiments of this utility model and are not intended to limit the scope of protection of this utility model. Therefore, all equivalent changes made to the structure, shape, and principle of this utility model should be included within the scope of protection of this utility model.
