[0032] In other embodiments, the cutter mechanism 6 may only include a cutter 601 fixedly mounted on the top of the base 1, and the cutter 601 is wedge-shaped.

[0033] The working principle of the fully automatic pathological tissue slicing device provided by the present invention is as follows: When in use, firstly, the paraffin-embedded pathological tissue is placed in the positioning frame 401. When the paraffin-embedded pathological tissue contacts the baffle 403, the paraffin-embedded pathological tissue pushes the baffle 403 to move, and the baffle 403 pushes the limit stop box 404 to move in the outer box 405. The first spring 402 and the second spring 411 are compressed. At this time, the limit post 408 moves in the limit groove 409, and the elastic plate 407 is twisted. When the limit post 408 contacts the inner wall of the limit groove 409 on one side away from the outer box 405, the paraffin-embedded pathological tissue cannot move. At this time, you only need to let go. Under the elastic force of the first spring 402 and the second spring 411, the limit post 408 is stuck in the slot on the limit groove 409. At this time, the installation of the paraffin-embedded pathological tissue is completed. After installation, less than half of the volume of the paraffin-embedded pathological tissue is located outside the positioning frame 401, which is convenient for slicing. The motor 209 is started, and the motor 209 drives the power shaft 202 to rotate through the first belt 210, and the power shaft 202 drives the connecting plate 203 to rotate, and the connecting plate 203 drives the lifting rod 204 to rotate with the power shaft 202 as the axis. When the lifting rod 204 rotates from bottom to top, the lifting rod 204 slides in the return bar 205 and drives the return bar 205 to move upward. The return bar 205 drives the two mounting blocks 206 to slide upward on the lifting rail 207, and the mounting blocks 206 drive the positioning frame 401 to move upward, thereby driving the paraffin-embedded pathological tissue to move upward. When the lifting rod 204 rotates from top to bottom, the paraffin-embedded pathological tissue moves downward, thereby realizing the up and down movement of the paraffin-embedded pathological tissue; While the motor 209 is rotating, the power shaft 202 drives the first rotating rod 301 to rotate through the second belt 302, the first rotating rod 301 drives the second rotating rod 305 to rotate through the first bevel gear 303 and the second bevel gear 304, the second rotating rod 305 drives the third rotating rod 307 to rotate through the third bevel gear 306 and the fourth bevel gear 308, and the third rotating rod 307 drives the internal threaded sleeve 311 to rotate on the outside of the translation screw 310 through the third belt 312, so that the internal threaded sleeve 311 rotates on the translation screw 310 while driving the support plate 201 to move toward the direction close to the cutter 601, so that the paraffin-embedded pathological tissue moves toward the direction close to the cutter 601, thereby realizing the automatic sectioning of the paraffin-embedded pathological tissue.

[0034] When the slicing is completed and the unsliced ​​paraffin-embedded pathological tissue needs to be removed, it is only necessary to continue pressing the paraffin-embedded pathological tissue to make the baffle plate 403 continue to move into the positioning frame 401. At this time, the limiting column 408 contacts the inner wall of the limiting groove 409 away from the outer box 405 again. At this time, the elastic force of the elastic plate 407 makes the elastic plate 407 parallel to the mounting plate 406. At this time, it is only necessary to loosen the paraffin-embedded pathological tissue, and the unsliced ​​paraffin-embedded pathological tissue can be ejected from the positioning frame 401 under the elastic force of the first spring 402 and the second spring 411. When it is necessary to clean the cutter 601, the positioning frame 401 and the baffle 403, it is only necessary to rotate the lifting screw 603. The lifting screw 603 rotates on the fixed block 602 and drives the first wedge block 604 to move upward until the first wedge block 604 moves to above the second wedge block 605. At this time, it is only necessary to pull the lifting screw 603 to disengage the cutter 601 from the protective cover 7, so that the cutter 601, the positioning frame 401 and the baffle 403 can be cleaned conveniently, and the protective cover and the elastic rubber plate 5 can also be cleaned conveniently, so as to ensure that the next slice will not be cross-contaminated.

[0035] Compared with the related art, the fully automatic pathological tissue slicing device provided by the present invention has the following beneficial effects: The present invention provides a fully automatic pathological tissue slicing device, which can quickly and conveniently install paraffin-embedded pathological tissue of a specific size through a paraffin pathological tissue block fixing mechanism 4 composed of a positioning frame 401, a first spring 402, a baffle 403, a limit stop box 404, an outer box 405, a mounting plate 406, an elastic plate 407, a limit column 408, a limit groove 409, a limit block 410 and a second spring 411, and can quickly and conveniently remove the paraffin-embedded pathological tissue that has not been sliced ​​from the positioning frame 401 after slicing is completed; The reciprocating motion locking mechanism 2 composed of the support plate 201, the power shaft 202, the connecting plate 203, the lifting rod 204, the return strip 205, the mounting block 206, the lifting rail 207, the rotating seat 208, the motor 209 and the first belt 210 can realize the longitudinal reciprocating motion of the paraffin-embedded pathological tissue, and the first rotating rod 301, the second belt 302, the first bevel gear 303, the second bevel gear 304, the second rotating rod 305, the third bevel gear 306, the third rotating rod 307, the fourth bevel gear 308, the mounting seat 310 and the second belt 311 can realize the longitudinal reciprocating motion of the paraffin-embedded pathological tissue. 09. The horizontal propulsion mechanism 3 composed of the translation screw 310, the internal threaded sleeve 311, the third belt 312, the slide rail 313 and the slider 314 can make the paraffin-embedded pathological tissue approach the cutter 601 while making longitudinal reciprocating motion, so as to cooperate with the cutter 601 to realize the automatic slicing of the paraffin-embedded pathological tissue; the elastic rubber plate 5 and the protective cover 7 cooperate to prevent the debris generated when slicing the paraffin-embedded pathological tissue from falling into the reciprocating motion locking mechanism 2 and the horizontal propulsion mechanism 3, and can ensure that the reciprocating motion locking mechanism 2 and the horizontal propulsion mechanism The normal movement of the propulsion mechanism 3 also avoids the cleaning of the reciprocating locking mechanism 2 and the horizontal propulsion mechanism 3; the cutter mechanism 6 composed of the cutter 601, the fixed block 602, the lifting screw 603, the first wedge block 604, the second wedge block 605, the sliding seat 606 and the sliding block 607 can cooperate with the reciprocating locking mechanism 2 and the horizontal propulsion mechanism 3 to realize automatic slicing of paraffin-embedded pathological tissue, and at the same time can facilitate the cleaning of debris after slicing, thereby avoiding cross contamination of paraffin-embedded pathological tissue during slicing.
