[0002] Pathological examination is a key technology in clinical diagnosis, especially for tumor biological specimens involving surgical resection or biopsy. The method involves processing the diseased tissue into pathological sections and staining it, and then observing the lesion under a microscope. Molecular detection of tumor tissue involves processing solid tumor tissue obtained by surgical resection or biopsy into tissue wax blocks and sections for subsequent tumor tissue sampling and analysis.

[0003] Generally, when slicing and sampling wax-coated tumor tissue, a microtome is used to cut the wax block into continuous long slices, and then a part of the long slice is cut and placed on a glass slide for subsequent operations. Although the existing slicing processing device can complete contactless slicing, it cannot automatically cut and sample and place it on a glass slide. Manual cutting operation is required, which increases the chance of medical staff contacting it and may affect the detection results of the slice. Utility Model Content

Obviously, the described implementation is a part of the implementation of the utility model, not all of the implementations. Based on the implementation of the utility model, all other implementations obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] A pathological section sampling device, such as Figure 1-4As shown, it includes: a slicer 100, a first conveyor belt 110, a guide roller 120, a second conveyor belt 130, a glass slide 140, a receiving mechanism 200, an intercepting mechanism 300 and a disassembling mechanism 400; the first conveyor belt 110 is arranged on one side of the slicer 100; the guide roller 120 is arranged on the side of the first conveyor belt 110 close to the slicer 100; the second conveyor belt 130 is arranged on the side of the first conveyor belt 110 away from the slicer 100; the glass slide 140 is arranged on the second conveyor belt 130; the receiving mechanism 200 is arranged on the first conveyor belt 110, and the receiving mechanism 200 is arranged in coordination with the guide roller 120; the intercepting mechanism 300 is arranged on the first conveyor belt 110, and the intercepting mechanism 300 is arranged in coordination with the receiving mechanism 200; the disassembling mechanism 400 is arranged on the receiving mechanism 200.

[0024] The slicer 100 is used to slice the wax-coated tumor tissue. Because the wax block needs to be cut into continuous long slices, the wax block needs to be cut alternately up and down. Therefore, the receiving mechanism 200 is used to drive the guide roller 120 to move up and down, and then the slice is received to avoid the slice being far away from the first conveyor belt 110, resulting in the slice being broken. Then, when the slice reaches the specified length, the intercepting mechanism 300 is used to cut the slice, and then it moves forward through the first conveyor belt 110 and finally falls to the second conveyor belt 130. When the slice completely falls onto the glass slide 140, the second conveyor belt 130 moves, and then another glass slide 140 is moved to the position of the first conveyor belt 110, and the above steps are repeated, so that the pathological slices can be continuously sampled without manually picking up the samples, thereby reducing the contact between medical staff and the slices; because the fixed plate 252 is used as a cutting pad for the slices for a long time, to prevent it from being damaged and unusable, the fixed plate 252 is configured to be detachable, and the disassembly mechanism 400 is used to disassemble and replace the fixed plate 252.

[0025] In the embodiment of the present utility model, Figure 1-4 As shown, the receiving mechanism 200 includes: a first electric push rod 210, a support block 220, a motor 230, a transmission shaft 240 and a guide member 250; the two first electric push rods 210 are symmetrically arranged on both sides of the first conveyor belt 110; the two support blocks 220 are respectively fixedly connected to the output ends of the two first electric push rods 210; the motor 230 is fixedly connected to one of the support blocks 220; both ends of the transmission shaft 240 are respectively rotatably connected to the two ends of the two support blocks 220 through bearings, and the transmission shaft 240 is transmission-connected to the output end of the motor 230, and the guide roller 120 is fixedly sleeved on the transmission shaft 240; the guide member 250 is arranged on the support block 220.

[0026] In the embodiment of the present utility model, Figure 1-4As shown, the guide member 250 includes: an inclined plate 251, a fixed plate 252 and a rubber abutment plate 253; the two ends of the inclined plate 251 are respectively fixedly connected to the two support blocks 220; the fixed plate 252 is movably connected to the inclined plate 251; one end of the rubber abutment plate 253 is fixedly connected to the fixed plate 252, and the other end of the rubber abutment plate 253 abuts against the guide roller 120.

[0027] Specifically, when the slicer 100 slices the tumor tissue, because the wax block needs to be cut into continuous long slices, the wax block needs to be cut alternately up and down, and the two first electric push rods 210 are started, so that the two first electric push rods 210 drive the two support blocks 220 to move up and down at the same time, thereby driving the guide roller 120 to move up and down. Since the inclined plate 251 is fixedly connected to the two support blocks 220, the guide member 250 is driven to move up and down at the same time, so the rubber abutment plate 253 always keeps abutting against the guide roller 120, and at the same time, the motor 230 is used to drive the transmission shaft 240 to rotate, thereby driving the guide roller 120 to rotate as well. This prevents the pathological slice from staying on the guide roller 120, so that the pathological slice moves downward along the fixed plate 252 and the rubber plate 253 as the guide roller 120 rotates, and finally moves to the first conveyor belt 110 for transmission; the fixed plate 252 and the rubber plate 253 are designed to be integrated, and the fixed plate 252 and the rubber plate 253 are both tilted, and there is no gap between the rubber plate 253 and the guide roller 120, so the slice will move downward in the direction of the fixed plate 252 and the rubber plate 253; the rubber plate 253 is provided with a rubber material to avoid friction between the guide roller 120 and the rubber plate 253 during the rotation process, thereby preventing wear.

[0028] In the embodiments of the present invention, Figure 1-4 As shown, the intercepting mechanism 300 includes: a support frame 310, a second electric push rod 320, a connecting plate 330 and a cutter 340; the support frame 310 is fixedly connected to both ends of the first conveyor belt 110; the fixed end of the second electric push rod 320 is fixedly connected to the support frame 310; the connecting plate 330 is fixedly connected to the output end of the second electric push rod 320; and the cutter 340 is fixedly connected to the connecting plate 330.

[0029] Specifically, the second electric push rod 320 is started to push the connecting plate 330 and the cutter 340 to move up and down. When the length of the slice reaches the specified range, the second electric push rod 320 is started to push the connecting plate 330 and the cutter 340 to move downward to cut the slice. The second electric push rod 320, the connecting plate 330 and the cutter 340 can be tilted, and their tilted cross section is perpendicular to the cross section of the fixed plate 252, which is conducive to cutting.

[0030] In the embodiments of the present invention, Figure 1-4As shown, the disassembly mechanism 400 includes: an L-shaped rod 410, a groove 420, a threaded hole 430, a connecting hole 440 and a fastening bolt 450; the L-shaped rod 410 is fixedly connected to the fixing plate 252; the groove 420 is opened on each support block 220, and the L-shaped rod 410 is inserted into the groove 420; the threaded hole 430 is opened on the side of the support block 220; the connecting hole 440 is opened on the L-shaped rod 410; the fastening bolt 450 is arranged in cooperation with the threaded hole 430 and the connecting hole 440.

[0031] Specifically, when it is necessary to remove the fixing plate 252, loosen the fastening bolts 450 on both sides to remove them from the threaded holes 430 and the connecting holes 440, and then the L-shaped rod 410 is freed from the restriction, so that the L-shaped rod 410 and the fixing plate 252 can be removed from the inclined plate 251. When it is necessary to install the fixing plate 252, first insert the L-shaped rods 410 on both sides of the fixing plate 252 into the grooves 420 on both sides respectively, and then screw the fastening bolts 450 into the threaded holes 430 and the connecting holes 440, and then fix the fixing plate 252 on the inclined plate 251, so as to facilitate the disassembly and replacement of the fixing plate 252 and avoid damage due to being used as a cutting pad for a long time.

[0032] In the embodiment of the present utility model, Figure 1-4 As shown, it also includes: a camera 150 and a heating device, the camera 150 is arranged above the slicer 100; the heating device is arranged below the second conveyor belt 130.

[0033] By setting up a camera 150, the length of the slice can be observed; by setting up a heating device under the second conveyor belt 130, the glass slide 140 can be heated so that the slice melts after being heated and sticks to the glass slide 140, which is convenient for later operations.

[0034] Implementation process: When in use, the slicer 100 slices the wax-wrapped tumor tissue. Because the wax block needs to be cut into continuous long slices, the wax block needs to be cut alternately up and down. When the slicer 100 cuts downward, the first electric push rod 210 drives the guide roller 120 and the guide member 250 to move from top to bottom. When the slicer 100 cuts upward, the first electric push rod 210 drives 120 and the guide member 250 to move from bottom to top, so that the slice is better received to avoid falling directly onto the first conveyor belt 110. The distance between the slice and the first conveyor belt 110 is too far and the slice is broken. Then, as the slice is gradually cut, the slice becomes longer and longer. When the camera 150 observes that the length of the slice reaches the specified range, the second electric push rod 320 is started to push the connecting plate 330 and the cutter 340 to move up and down. When the length of the slice reaches the specified range, the second electric push rod 320 is started to push the connecting plate 330 and the cutter 340 to move downward to cut the slice. After cutting, the slice falls completely onto the first conveyor belt 110. As the first conveyor belt 110 moves, it moves to the side of the second conveyor belt 130 and falls onto the placed glass slide 140. Then, the pathological slice can be sampled without manual picking of samples, thereby reducing the contact between medical staff and the slice.

[0035] It should be noted that the specific models and specifications of the first electric push rod 210, the motor 230, the second electric push rod 320, the camera 150 and the heating device need to be selected and determined according to the actual specifications of the device, so they will not be described in detail.

[0036] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. For those skilled in the art, the present invention may be modified and varied in various ways. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
