Description

Technical Field

[0001] The present invention relates to the field of pathological slicing equipment, and more specifically to a clinical pathological diagnosis sampling and slicing device. Background Art

[0002] When doing drug experiments, in order to study the drug ingredients and therapeutic effects of a new drug, we must first use small animals for the experiment. After the experimental animals are grouped, an experimental animal model is established. The pathological tissue is then cut from the animal model to make tissue blocks. The tissue blocks are then placed in a fixative for fixation. After dehydration, wax immersion, and embedding, they are sliced ​​and finally the slices are placed under a microscope for observation.

[0003] However, in the prior art, when slicing, after slicing the pathological tissue once, the pathological tissue needs to be adjusted manually, and the pathological tissue needs to be pushed manually to the bottom of the blade, which is very inconvenient during operation and has a certain impact on the accuracy of the adjustment.

[0010] Further, the variable pitch mechanism includes a first sleeve rotatably connected to one side of the threaded rod. Three fixing holes are opened at the middle position of the outer surface of the first sleeve. A second sleeve is slidably connected inside the first sleeve. Three second gears are fixedly connected to the outer surface of the second sleeve. A third spring is fixedly connected to the inner surface of the second sleeve. The top of the third spring is fixedly connected with a movable plate. A clamping rod and a pressing rod are respectively fixedly connected to the two sides of the upper surface of the movable plate.

[0011] Further, the tops of the clamping rod and the pressing rod both penetrate and extend out of the inside of the second sleeve.

[0017] Compared with the prior art, the present invention has the following beneficial effects:

[0018] 1. This scheme is provided with a feeding mechanism. When the cutting knife and the cutting knife mounting plate rise, the push rod will contact the right-angled side of the trapezoidal plate and push the trapezoidal plate to rotate, thereby driving the threaded rod to rotate, and the threaded rod drives the placement plate to move through the internal threaded sleeve block. Because the length of the second rack is constant, the number of rotations of the variable pitch mechanism is constant, so that after each slicing is completed, the placement plate moves a certain distance, and the moving distance is the thickness of the slice, which effectively ensures the accuracy of slicing.

[0019] 2. This solution is equipped with an anti-backoff mechanism to prevent the placement plate from moving away from the cutting knife. This can effectively ensure that when the second rack moves downward to drive the pitch-changing mechanism to rotate, the threaded rod will not be driven to rotate through the transmission, thereby effectively ensuring the accuracy of the placement of the plate.

[0020] 3. This solution can adjust the position of the second gear by providing a variable pitch mechanism. The smaller the diameter of the second gear, the more turns the threaded rod makes, the longer the placement plate moves, and vice versa, the shorter the placement plate moves. This can adapt to the needs of different slice thicknesses and can cope with slices of different pathological tissues, greatly improving efficiency and reducing the trouble of replacing different slicing equipment.

[0021] 4. This solution is provided with a grinding mechanism, and the grinding groove continuously rubs back and forth on the blade of the cutting knife, which can continuously grind the blade of the cutting knife, making the blade of the cutting knife sharper. When slicing the pathological tissue, the surface of the pathological tissue can be flatter and smoother, which is convenient for subsequent observation of the pathological tissue.

[0022] 5. This solution is provided with a rotating mechanism, so that the grinding stone rotates while moving, which can not only greatly improve the grinding effect of the cutting knife, but also avoid the wear caused by the use of the same position, which will cause the subsequent grinding effect to deteriorate.

[0023] 6. This solution is equipped with a collection mechanism, and the polished metal debris tube falls into the inside of the collection box for collection, which effectively avoids the splash of debris. At the same time, the cleaning brush is located inside the polishing groove, and the cleaning brush can clean up the debris remaining in the polishing groove in time to avoid the residue of debris. The cleaned debris is collected by the collection box. BRIEF DESCRIPTION OF THE DRAWINGS

[0047] The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention; obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0048] Please refer to Figures 1 to 11 , a clinical pathological diagnosis sampling and slicing device, including a base 1, a mounting frame 2 fixedly connected to one side of the upper surface of the base 1, an electric push rod 3 fixedly connected to the upper surface of the mounting frame 2, a cutting knife mounting plate 7 fixedly connected to the output end of the electric push rod 3, a cutting knife 4 fixedly connected to the lower surface of the cutting knife mounting plate 7, a grinding mechanism 5 fixedly connected to one side of the mounting frame 2, and a feeding mechanism 6 fixedly connected to the front and rear sides of the upper surface of the base 1.

[0049] As Figure 6 , Figure 7 and Fig.10 shown, the feeding mechanism 6 includes an anti-backward mechanism 63 fixed to the front and rear sides of the upper surface of the base 1, a mounting rod 620 fixed to one side of the cutting knife mounting plate 7, and a through hole 65 opened inside the base 1. A U-shaped plate 64 is slidably connected to the outer surface of the anti-backward mechanism 63. A placing plate 61 is fixedly connected to the upper surface of the U-shaped plate 64. Second fixing plates 67 are fixedly connected to both sides of the upper surface of the placing plate 61. A first sliding rod 610 is slidably connected inside the two second fixing plates 67. A fourth spring 69 is sleeved on the outer surfaces of the two first sliding rods 610. An arc-shaped clamping plate 68 is fixedly connected to the side of the two first sliding rods 610 close to each other. A chute 612 is opened at the middle position of the lower surface of the placing plate 61. A fifth spring 613 is fixedly connected to one side of the inner surface of the chute 612. An internally threaded sleeve block 611 is slidably connected inside the chute 612. A threaded rod 62 is threadedly connected inside the internally threaded sleeve block 611. One side of the threaded rod 62 is rotatably connected to a variable pitch mechanism 66. Four third fixing plates 616 are fixedly connected to one side of the outer surface of the threaded rod 62. A second sliding rod 615 is slidably connected inside the third fixing plates 616. A trapezoidal plate 617 is fixedly connected to one side of the second sliding rod 615. A sixth spring 614 is sleeved on the outer surface of the second sliding rod 615. A second rack 619 is hinged to the lower surface of the mounting rod 620. A coil spring 618 is provided at the hinge of the second rack 619 and the mounting rod 620. Four push rods 621 are fixedly connected to one side of the outer surface of the variable pitch mechanism 66.

[0050] The second rack 619 is located directly above the through hole 65. One side of the fifth spring 613 is fixedly connected to one side of the internally threaded sleeve block 611.

[0051] By providing a feeding mechanism 6, when slicing a case, two first sliding rods 610 are pulled to drive two arc-shaped clamping plates 68 to move away from each other, and the processed pathological tissue is placed on the placing plate 61. Then, the two first sliding rods 610 are released, and two fourth springs 69 push the arc-shaped clamping plates 68 to clamp and fix the pathological tissue. At this time, the second rack 619 is rotated around the coil spring 618 to move away from the variable pitch mechanism 66. Then, the threaded rod 62 is rotated, and the placing plate 61 is driven by the internal thread sleeve block 611 to move below the cutting knife 4. When the pathological tissue moves below the cutting knife 4, the second rack 619 is released and contacts and meshes with the variable pitch mechanism 66 under the action of the coil spring 618. At this time, the electric push rod 3 is turned on to drive the cutting knife 4 and the cutting knife mounting plate 7 to move downward, and the cutting knife 4 cuts the pathological tissue. When the cutting knife mounting plate 7 descends, it drives the mounting rod 620 and the first sliding rod 610 to descend simultaneously. The second rack 619 drives the variable pitch mechanism 66 to rotate, and the variable pitch mechanism 66 drives four push rods 621 to rotate. The push rods 621 rotate and contact the hypotenuse of the trapezoidal plate 617, thereby pushing the trapezoidal plate 617 to approach the third fixing plate 616. When the push rods 621 continue to rotate and pass through the trapezoidal plate 617, when the cutting knife 4 and the cutting knife mounting plate 7 descend, the variable pitch mechanism 66 rotates without driving the threaded rod 62 to rotate, thereby avoiding the movement of the placing plate 61 and effectively preventing the pathological tissue from moving during cutting;

[0052] When the cutting knife 4 and the cutting knife mounting plate 7 rise and the cutting knife 4 is separated from the pathological tissue, the second rack 619 meshes with the variable pitch mechanism 66 again, driving the variable pitch mechanism 66 to reverse, so that the variable pitch mechanism 66 drives the four push rods 621 to reverse. The push rods 621 will contact the right-angle side of the trapezoidal plate 617 and push the trapezoidal plate 617 to rotate, thereby driving the threaded rod 62 to rotate. Then, the threaded rod 62 drives the placing plate 61 to move through the internal thread sleeve block 611. Since the length of the second rack 619 is fixed, the number of turns of the variable pitch mechanism 66 is fixed, so that each time after slicing, the moving distance of the placing plate 61 is fixed, and the moving distance is the thickness of the slice, effectively ensuring the accuracy during slicing.

[0053] As Figure 7 - Fig. 9 shown, the anti-backward mechanism 63 includes hollow rods 631 fixed to the front and rear sides of the upper surface of the base 1 and a second thorn rack 636 fixed to the inner top of the U-shaped plate 64. A through groove 632 is provided on the upper surface of the hollow rod 631. Two second fixing rods 635 are fixedly connected to the inner bottom of the hollow rod 631. A second spring 633 is sleeved on the outer surface of the second fixing rod 635. The tops of the two second springs 633 are fixedly connected to a first thorn rack 634. The first thorn rack 634 slides on the outer surface of the second fixing rod 635. The second fixing rod 635 is located inside the through groove 632 and meshes with the first thorn rack 634.

[0054] The above-mentioned embodiment is provided with a feeding mechanism 6, which can automatically load the material during slicing to avoid the problem of accuracy deviation caused by manual loading. However, when the push rod 621 reverses, there will always be a thrust in the direction of the push rod 621, and the threaded rod 62 may rotate at a certain angle, which will cause the placement plate 61 to move, and the distance of the placement plate 61 during subsequent loading will change, resulting in uneven slice thickness.

[0055] By providing an anti-retraction mechanism 63, when the push rod 621 is reversed, the thrust in the direction of the push rod 621 will drive the threaded rod 62 to rotate a certain angle, so that the placement plate 61 moves away from the cutting knife 4, but the first thorn rack 634 and the second thorn rack 636 are meshed with each other, so that when the hollow plate 64 moves on the hollow rod 631, the beveled edge of the teeth on the first thorn rack 634 contacts the teeth on the second thorn rack 636, and the second thorn rack 636 moves toward the direction of the cutting knife 4, so that the beveled edges of the teeth of the first thorn rack 634 and the second thorn rack 636 are meshed with each other. They slide against each other, so that the first thorn rack 634 continuously shakes up and down on the outside of the second fixed rod 635. When the placement plate 61 moves in the opposite direction, the right-angled sides of the second thorn rack 636 and the first thorn rack 634 contact each other, so that the first thorn rack 634 blocks the second thorn rack 636 from moving away from the cutting knife 4, thereby preventing the placement plate 61 from moving away from the cutting knife 4. This can effectively ensure that when the second rack 619 moves downward to drive the pitch change mechanism 66 to rotate, it will not drive the threaded rod 62 to rotate through the transmission, thereby effectively ensuring the accuracy of the placement plate 61 when loading.

[0056] like Fig.10 and Fig.11 As shown, the pitch changing mechanism 66 includes a first sleeve 661 rotatably connected to one side of the threaded rod 62, three fixing holes 664 are opened in the middle position of the outer surface of the first sleeve 661, the second sleeve 662 is slidably connected inside the first sleeve 661, three second gears 665 are fixedly connected to the outer surface of the second sleeve 662, a third spring 668 is fixedly connected to the inner surface of the second sleeve 662, a movable plate 667 is fixedly connected to the top of the third spring 668, and a clamping rod 663 and a pressing rod 666 are respectively fixedly connected to the two sides of the upper surface of the movable plate 667.

[0057] The tops of the latch rod 663 and the pressing rod 666 extend through the interior of the second sleeve 662, the top of the latch rod 663 passes through the interior of the fixing hole 664 and is adapted to the fixing hole 664, the three second gears 665 have different diameters, and the three second gears 665 are all meshed with the second rack 619.

[0058] The above embodiment is provided with an anti-retraction mechanism 63, which can prevent the placement plate 61 from accidentally rotating after each slicing is completed, thereby ensuring that the thickness of each slice is constant. However, different pathological tissues require different slice thicknesses, which causes limitations to the equipment.

[0059] By providing a variable distance mechanism 66, when slicing different pathological tissues, it is necessary to adjust the moving distance of the placement plate 61. The pressing rod 666 is pressed downward to drive the clamping rod 663 to move out of the fixing hole 664 through the movable plate 667, thereby releasing the fixing effect between the first sleeve 661 and the second sleeve 662. At this time, the second sleeve 662 is pulled to drive the second gear 665 to move, and the three second gears 665 can be adjusted to mesh with the second rack 619 respectively. When the second rack 619 is adjusted from the second gear 665 with a large diameter to the second gear 665 with a small diameter, the fifth spring 613 pushes the internal threaded sleeve block 611 to move inside the slide groove 612, driving the threaded rod 62, the first sleeve 661 and The second sleeve 662 as a whole approaches the second rack 619, and the second rack 619 approaches the second gear 665 under the action of the coil spring 618. The second gear 665 is always meshed with the second rack 619. When a larger diameter second gear 665 is required to mesh with the second rack 619, the internal threaded sleeve 611 can be pushed to move inside the slide groove 612 to adjust the position of the second gear 665. The smaller the diameter of the second gear 665, the more turns it makes, the more turns the threaded rod 62 makes, and the longer the distance the placement plate 61 moves. Conversely, the shorter the distance the placement plate 61 moves, so that it can adapt to the needs of different slice thicknesses and can cope with the slices of different pathological tissues, greatly improving efficiency and reducing the trouble of replacing different slicing equipment.

[0060] like Figure 2 - Figure 4 As shown, the grinding mechanism 5 includes a side plate 51 fixed on one side of the mounting frame 2, two pull rods 52 are slidably connected through the middle position of one side inside the side plate 51, a rectangular frame 53 is fixedly connected to one side of the two pull rods 52, a collecting mechanism 55 is sleeved on the lower surface of the rectangular frame 53, grinding stones 56 are fixedly connected to both sides of the upper surface of the rectangular frame 53, grinding stones 56 are rotatably connected to both sides of the inner surface of the anti-backward mechanism 63, a grinding groove 57 is provided on the outer surface of the grinding stone 56, and a rotating mechanism 54 is rotatably connected to one side of the rectangular frame 53.

[0061] The grinding groove 57 and the cutting blade 4 are matched with each other, and the two grinding stones 56 are located on both sides of the cutting blade 4 .

[0062] As the cutting knife 4 cuts for a long time, the cutting knife 4 and the placement plate 61 are constantly in contact, which may cause the edge of the cutting knife 4 to curl. If not handled in time, it may damage the pathological tissue and cause the slice quality to be unqualified.

[0063] By providing a grinding mechanism 5, the surface of the cutting knife 4 that has been used for a period of time can be ground. The two pull rods 52 are pushed to drive the rectangular frame 53 and the grinding stone 56 to move. The rectangular frame 53 approaches the cutting knife 4, so that the cutting knife 4 enters the inside of the grinding groove 57 through the two grinding stones 56. The grinding groove 57 continuously rubs back and forth on the blade of the cutting knife 4, and the blade of the cutting knife 4 can be continuously ground, making the blade of the cutting knife 4 sharper. When slicing the pathological tissue, the surface of the pathological tissue can be flatter and smoother, which is convenient for subsequent observation of the pathological tissue.

[0064] like Figure 2 - Figure 4 As shown, the rotating mechanism 54 includes a transmission shaft 542 rotating on one side of the rectangular frame 53 and a first rack 541 fixed on one side of the side plate 51, and a first gear 543 is fixedly connected to one side of the transmission shaft 542. The first gear 543 and the first rack 541 are meshed with each other, and the transmission shaft 542 passes through the rectangular frame 53 and is fixedly connected to one side of the grinding stone 56.

[0065] The above embodiment can effectively grind the blade of the cutting knife 4 by providing the grinding mechanism 5, but the grinding stone 56 is in a fixed state, so that the grinding position inside the grinding groove 57 remains unchanged, which will cause wear at the grinding position and deteriorate the subsequent grinding effect.

[0066] By providing a rotating mechanism 54, when the rectangular frame 53 drives the grinding stone 56 to move back and forth on the surface of the cutting knife 4, the first gear 543 continuously moves and rotates above the first rack 541, and drives the grinding stone 56 to rotate through the transmission shaft 542, so that the grinding stone 56 rotates while moving, which can not only greatly improve the grinding effect of the cutting knife 4, but also avoid the wear caused by the use of the same position, which will cause the subsequent grinding effect to deteriorate.

[0067] like Figure 3 - Figure 5 As shown, the collecting mechanism 55 includes a first fixing rod 552 fixed at the bottom of both sides of the rectangular frame 53 and a connecting groove 558 opened on the lower surface of the rectangular frame 53, and a collecting box 551 is sleeved inside the connecting groove 558. The two sides of the collecting box 551 are fixedly connected with a first fixing plate 553, and one side of the first fixing plate 553 is fixedly connected with a supporting rod 555. The outer surface of the collecting mechanism 55 is sleeved with a first spring 554, and one side of the first spring 554 is fixedly connected with a hook 556. The bottom of the collecting box 551 is fixedly connected with a cleaning brush 557, and the cleaning brush 557 is located inside the grinding groove 57 and fits tightly.

[0068] The top of the hook 556 is inclined, and the hook 556 is located on the outer side of the support rod 555 and slides.

[0069] The above embodiment is provided with a rotating mechanism 54, which can drive the grinding stone 56 to rotate through transmission when the grinding stone 56 moves, thereby further improving the grinding effect of the cutting knife 4. However, the grinding debris will splash onto the workbench, which will cause contamination to the pathological tissue when the pathological tissue is subsequently sliced.

[0070] By providing a collecting mechanism 55, when the grinding stone 56 grinds the cutting blade 4, the grinded metal debris barrel falls into the inside of the collecting box 551 for collection, effectively avoiding the splashing of debris. At the same time, the cleaning brush 557 is located inside the grinding groove 57, and the cleaning brush 557 can timely clean up the debris remaining inside the grinding groove 57 to avoid the residue of debris. The cleaned debris is collected by the collecting box 551. When the debris inside the collecting box 551 needs to be processed, the two hooks 556 are pushed to slide on the outside of the support rod 555. , the hook 556 is detached from the outside of the first fixing rod 552, and the collection box 551 can be taken out downward from the inside of the connecting groove 558. During installation, the collection box 551 is aligned with the inside of the connecting groove 558 and inserted. The hypotenuse of the hook 556 contacts the first fixing rod 552, which will push the hook 556 to slide on the outside of the support rod 555 and squeeze the first spring 554. When the hook 556 passes through the first fixing rod 552, the first spring 554 pushes the hook 556 to move and get stuck on the outside of the first fixing rod 552, completing the installation of the collection box 551.

[0071] Instructions for use: First, fix the pathological tissue through two arc-shaped clamping plates 68, separate the second rack 619 and the second gear 665 from each other, rotate the threaded rod 62 to drive the placement plate 61 to move through the internal threaded sleeve 611, and drive the pathological tissue to move below the cutting knife 4. The second rack 619 can drive the second gear 665 to rotate as the cutting knife mounting plate 7 rises, and the second gear 665 drives the second sleeve 662 to rotate. Under the cooperation of the clamping rod 663 and the fixing hole 664, the first sleeve 661 synchronously drives the push rod 621 to rotate, and the push rod 621 and the trapezoidal plate 617 cooperate to drive the threaded rod 62 to rotate, so that automatic loading can be performed. When the second rack 619 moves downward and drives the second gear 665 to reverse, the anti-backoff mechanism 63 can prevent the placement plate 61 from moving in the opposite direction, thereby ensuring the accuracy of feeding.

[0072] Then, when different slice thicknesses are needed, the three second gears 665 with different diameters can be adjusted. When the second gear 665 with a smaller diameter is meshed with the second rack 619 for transmission, the second gear 665 with a smaller diameter rotates more times, the threaded rod 62 rotates more times, the placement plate 61 moves a greater distance, and the slice thickness becomes greater.

[0073] Finally, the blade of the cutting knife 4 can be continuously polished by the grinding stone 56, and under the action of the rotating mechanism 54, the grinding stone 56 can rotate to further improve the grinding effect. At the same time, the collection box 551 can collect the grinding debris, and the cleaning brush 557 can clean the debris remaining inside the grinding groove 57.

[0074] The above is only a preferred specific implementation of the present invention; however, the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical solution and its improved conception within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
