It can precisely cut tissue samples into micron-sized slices to meet the needs of pathological and biological research. During the cutting process, it can also protect the integrity and structure of the sample to the greatest extent and ensure the quality of the slices.
[0003] In the process of realizing this utility model, the inventors discovered the following problems in the prior art:
[0004] Existing paraffin slicers require separate adjustment of the positions of the paraffin holder and the blade holder, which increases the operation time and complexity of the paraffin slicer. Utility Model Content
[0005] In view of the above problems, this application provides a paraffin microtome for pathological sections, which solves the technical problem that existing paraffin microtomes require separate adjustment of the positions of the paraffin holder and the blade holder, which increases the operation time and complexity of the paraffin microtome.
[0006] To achieve the above objectives, in a first aspect, this application provides a paraffin microtome for pathological sections, comprising:
[0007] The base has a first groove and two second sliding grooves. The two second sliding grooves are symmetrically arranged on both sides of the first groove. A first slider is slidably arranged in each of the two second sliding grooves. A first rotating rod is rotatably arranged in the base. A second rotating rod is arranged in each of the two second sliding grooves. The first rotating rod is connected to the two second rotating rods through bevel gears. The two second rotating rods are threadedly connected to the two first sliders.
[0008] A housing, which is mounted on the base;
[0009] A paraffin wax holder, the paraffin wax holder being connected to one of the first sliders; and
[0010] The tool holder is connected to another first slider. Through the cooperation of a first rotating rod and two second rotating rods, the paraffin holder and the tool holder are driven to move closer to each other or further away from each other.
[0011] Unlike existing technologies, the technical solution of this application features a base with a first groove and two second sliding grooves symmetrically arranged on both sides of the first groove. A first slider is slidably mounted within each of the two second sliding grooves. A first rotating rod is rotatably mounted within the base, and a second rotating rod is mounted within each of the two second sliding grooves. The first rotating rod is connected to the two second rotating rods via bevel gears, and the two second rotating rods are threadedly connected to the two first sliders. A paraffin wax holder is connected to one of the first sliders, and a tool holder is connected to the other first slider. Through the cooperation of the first rotating rod and the two second rotating rods, the paraffin wax holder and the tool holder are simultaneously driven to move closer or further apart. Thus, only the first rotating rod needs to be rotated to simultaneously move the positions of the paraffin wax holder and the tool holder, reducing the operation time of the paraffin wax slicer and simplifying its operation.
[0012] In one embodiment of this utility model, a first bevel gear is provided at one end of the first rotating rod, and a second bevel gear is provided at one end of the second rotating rod. The first bevel gear meshes with the second bevel gear. The first rotating rod and the two second rotating rods are arranged in a T-shape. The first bevel gear and the second bevel gear are disposed in the first groove.
[0013] Thus, both second rotating rods are equipped with second bevel gears, which mesh with the first bevel gears respectively. By rotating the first rotating rod, the first bevel gear is driven to rotate, and the rotation of the first bevel gear simultaneously drives the two second bevel gears to rotate, thereby driving the two second rotating rods to rotate and causing the two first sliders to move closer to or further away from each other.
[0014] In one embodiment of this utility model, the second rotating rod is provided with an external thread, and the first slider is provided with an internal thread. The internal thread meshes with the external thread, and the second rotating rod drives the first slider to slide relative to each other along the extension direction of the second groove.
[0015] Thus, the second rotating rod extends along the extension direction of the second slide groove. Through the cooperation of the internal and external threads, it can drive the first slider to slide relative to the extension direction of the second slide groove. The size and shape of the first slider match the second slide groove, and the first slider can slide inside the second slide groove.
[0016] In one embodiment of this utility model, a first rotating wheel is provided at the other end of the first rotating rod, and the first rotating wheel is disposed outside the base.
[0017] Thus, the first rotating rod can be rotated by the first rotating wheel, thereby causing the paraffin holder and the tool holder to move closer to or further apart.
[0018] In one embodiment of this utility model, the paraffin sectioning machine for pathological sections further includes a U-shaped plate, a support block, a reciprocating screw, and a rotating shaft. The U-shaped plate is fixedly mounted on one of the first sliders, the reciprocating screw is rotatably mounted on the U-shaped plate, the support block is threadedly mounted on the reciprocating screw, the housing is provided with a first sliding groove, the support block is slidably mounted on the first sliding groove, the paraffin wax holder is mounted on the support block, and the rotating shaft is driven by the reciprocating screw. The rotating shaft drives the paraffin wax holder to rise and fall through the cooperation between the reciprocating screw and the support block.
[0019] Thus, by driving the rotation of the rotating shaft, the reciprocating lead screw can be driven to rotate, causing the support block to move up and down, thereby causing the paraffin wax holder to move up and down, thus enabling the paraffin wax to be sliced.
[0020] In one embodiment of this utility model, the reciprocating lead screw is arranged in a vertical direction, the first slide groove extends in a vertical direction, and the rotating shaft drives the support block to slide up and down in a vertical direction through the reciprocating lead screw.
[0021] In this way, the support block can move up and down vertically within the first groove, which facilitates the movement of the paraffin wax holder up and down.
[0022] In one embodiment of this utility model, a third bevel gear is provided on the rotating shaft, a fourth bevel gear is provided on the reciprocating screw, the third bevel gear meshes with the fourth bevel gear, a through groove is provided on the side of the housing, the rotating shaft passes through the through groove in a horizontal direction, and a turntable is provided at one end of the rotating shaft.
[0023] In this way, the rotating turntable can drive the rotation of the rotating shaft. The rotating shaft drives the reciprocating screw to rotate through the cooperation of the third bevel gear and the fourth bevel gear. At the same time, since the rotating shaft needs to pass through the spiral plate, the spiral plate will move together with the first slider. The rotating shaft needs to move together with the spiral plate and move together in the through groove.
[0024] In one embodiment of this utility model, the turntable is provided with a handle, the handle is provided with a protective pad, the through groove extends along the sliding direction of the first slider, the rotating shaft is disposed in the through groove via a second slider, and the second slider is slidably disposed in the through groove.
[0025] In this way, the rotation of the turntable can be easily driven by the handle. Since the rotating shaft needs to pass through the spiral plate, the spiral plate will move together with the first slider. The rotating shaft needs to move together with the spiral plate. Therefore, the rotating shaft will drive the second slider to move together in the through slot. The rotating shaft will not interfere with the box.
[0026] In one embodiment of this utility model, a cutting blade is provided on the tool holder, and a second groove is provided on the tool holder, the second groove being positioned opposite the cutting blade. A third rotating rod is rotatably disposed within the second groove, and a rotating plate is provided on the third rotating rod. The paraffin microtome for pathological sections also includes a motor, which is disposed on the tool holder, and the output end of the motor is connected to the third rotating rod for transmission.
[0027] In this way, the cutter slices the paraffin wax, and then the slices are pushed into the collection box by a rotating plate.
[0028] In one embodiment of this utility model, the paraffin microtome for pathological sections further includes a collection box. A third groove is provided on the base, and a third slider is provided on the third groove. The collection box is slidably mounted on the base via the third slider, and the collection box is positioned relative to the rotating plate.
[0029] In this way, the slices are collected by the collection box, which can slide relative to the base via the third slider. The extension direction of the third groove is the same as the extension direction of the second groove.

[0053] According to some embodiments of this application, please refer to Figures 1 to 7 This embodiment relates to a paraffin sectioning machine for pathological sections, including a base 1, a housing 3, a paraffin holder 6, and a tool holder 8. The base 1 is provided with a first groove 12 and two second sliding grooves 9. The two second sliding grooves 9 are symmetrically arranged on both sides of the first groove 12. A first slider 11 is slidably arranged in each of the two second sliding grooves 9. A first rotating rod 13 is rotatably arranged in the base 1. A second rotating rod 10 is arranged in each of the two second sliding grooves 9. The first rotating rod 13 is connected to the two second rotating rods 10 through bevel gears. The two second rotating rods 10 are threadedly connected to the two first sliders 11. The housing 3 is arranged on the base 1. The paraffin holder 6 is connected to one of the first sliders 11. The tool holder 8 is connected to the other first slider 11. Through the cooperation of the first rotating rod 13 and the two second rotating rods 10, the paraffin holder 6 and the tool holder 8 are simultaneously driven to move closer to each other or further away from each other.
[0054] In this embodiment, a desktop panel 2 is provided at the bottom of the base 1;
[0055] In some embodiments, the housing 3 has a hollow structure, and the lifting mechanism of the paraffin wax holder 6 is disposed inside the housing 3;
[0056] In some embodiments, the paraffin wax holder 6 is used to fix the paraffin wax, and the knife holder 8 is used to fix the cutting knife. The paraffin wax holder 6 can drive the paraffin wax to move up and down in the vertical direction, closer to or away from the cutting knife, so as to achieve paraffin wax slicing. The slicing process of paraffin wax is a conventional technical means, which will not be described in detail here.
[0057] In this embodiment, a first groove 12 and two second sliding grooves 9 are provided on the base 1. The two second sliding grooves 9 are symmetrically arranged on both sides of the first groove 12. A first slider 11 is slidably arranged in each of the two second sliding grooves 9. A first rotating rod 13 is rotatably arranged in the base 1. A second rotating rod 10 is arranged in each of the two second sliding grooves 9. The first rotating rod 13 is connected to the two second rotating rods 10 through bevel gears. The two second rotating rods 10 are threadedly connected to the two first sliders 11. The paraffin wax holder 6 is connected to one of the first sliders 11. The tool holder 8 is connected to the other first slider 11. Through the cooperation of the first rotating rod 13 and the two second rotating rods 10, the paraffin wax holder 6 and the tool holder 8 are simultaneously driven to move closer to each other or further away from each other.
[0058] In this way, the positions of the paraffin wax holder 6 and the cutter holder 8 can be moved simultaneously by simply rotating the first rotating rod 13, reducing the operation time of the paraffin wax slicer and simplifying its operation.
[0059] According to some embodiments of this application, optionally, a first bevel gear 14 is provided at one end of the first rotating rod 13, and a second bevel gear 15 is provided at one end of the second rotating rod 10.

[0060] Thus, each of the two second rotating rods 10 is provided with a second bevel gear 15, and the two second bevel gears 15 mesh with the first bevel gear 14 respectively. By rotating the first rotating rod 13, the first bevel gear 14 is driven to rotate. The rotation of the first bevel gear 14 simultaneously drives the two second bevel gears 15 to rotate, thereby driving the two second rotating rods 10 to rotate, causing the two first sliders 11 to move closer to each other or further away from each other.
[0061] According to some embodiments of this application, optionally, the second rotating rod 10 is provided with an external thread, and the first slider 11 is provided with an internal thread. The internal thread and the external thread mesh with each other, and the second rotating rod 10 drives the first slider 11 to slide relative to each other along the extension direction of the second sliding groove 9.
[0062] Thus, the second rotating rod 10 extends along the extension direction of the second slide groove 9. Through the cooperation of the internal thread and the external thread, it can drive the first slider 11 to slide relative to the extension direction of the second slide groove 9. The size and shape of the first slider 11 match the second slide groove 9, and the first slider 11 can slide within the second slide groove 9.
[0063] According to some embodiments of this application, optionally, a first rotating wheel 16 is provided at the other end of the first rotating rod 13, and the first rotating wheel 16 is disposed outside the base 1.
[0064] Thus, the first rotating rod 13 can be rotated by the first rotating wheel 16, thereby causing the paraffin wax holder 6 and the knife holder 8 to move closer to or further apart from each other.
[0065] According to some embodiments of this application, optionally, such as Figure 2 and Figure 4 As shown, the paraffin sectioning machine for pathological sections also includes a spiral plate 7, a support block 5, a reciprocating screw 21, and a rotating shaft 19. The spiral plate 7 is fixedly mounted on one of the first sliders 11. The reciprocating screw 21 is rotatably mounted on the spiral plate 7. The support block 5 is threadedly mounted on the reciprocating screw 21. The housing 3 is provided with a first slide groove 4. The support block 5 is slidably mounted on the first slide groove 4. The paraffin wax holder 6 is mounted on the support block 5. The rotating shaft 19 is driven by the reciprocating screw 21. The rotating shaft 19 drives the paraffin wax holder 6 to rise and fall through the cooperation between the reciprocating screw 21 and the support block 5.
[0066] The rotating shaft 19 passes through the side wall of the spiral plate 7 and is connected to the reciprocating lead screw 21 for transmission.
[0067] Thus, by driving the rotation of the rotating shaft 19, the reciprocating screw 21 can be driven to rotate, causing the support block 5 to move up and down, thereby causing the paraffin wax holder 6 to move up and down, thus achieving the slicing of paraffin wax.
[0068] According to some embodiments of this application, optionally, the reciprocating screw 21 is arranged in the vertical direction, the first slide groove 4 extends in the vertical direction, and the rotating shaft 19 drives the support block 5 to slide up and down in the vertical direction through the reciprocating screw 21.

[0070] According to some embodiments of this application, optionally, a third bevel gear 20 is provided on the rotating shaft 19, and a fourth bevel gear 22 is provided on the reciprocating screw 21. The third bevel gear 20 and the fourth bevel gear 22 mesh with each other. A through groove 17 is provided on the side of the housing 3.

[0071] The third bevel gear 20 and the fourth bevel gear 22 are installed inside the spiral plate 7;
[0072] Thus, the rotating turntable 24 can drive the rotation of the rotating shaft 19. The rotating shaft 19 drives the reciprocating screw 21 to rotate through the cooperation of the third bevel gear 20 and the fourth bevel gear 22. At the same time, since the rotating shaft 19 needs to pass through the spiral plate 7, the spiral plate 7 will move together with the first slider 11. The rotating shaft 19 needs to move together with the spiral plate 7. The rotating shaft 19 needs to move together within the through groove 17.
[0073] According to some embodiments of this application, optionally, a handle 25 is provided on the turntable 24, a protective pad is provided on the handle 25, a through groove 17 extends along the sliding direction of the first slider 11, and a rotating shaft 19 is disposed in the through groove 17 via a second slider 18, the second slider 18 being slidably disposed in the through groove 17.
[0074] Thus, the handle 25 facilitates the rotation of the turntable 24. Since the rotating shaft 19 needs to pass through the loop plate 7, the loop plate 7 will move together with the first slider 11. The rotating shaft 19 needs to move together with the loop plate 7. The rotating shaft 19 will drive the second slider 18 to move together in the through groove 17, so that the rotating shaft 19 moves together with the first slider 11. The rotating shaft 19 will not interfere with the housing 3.
[0075] According to some embodiments of this application, optionally, a cutting blade is provided on the tool holder 8, and a second groove 26 is provided on the tool holder 8. The second groove 26 is disposed opposite to the cutting blade. A third rotating rod 28 is rotatably disposed in the second groove 26. A rotating plate 29 is provided on the third rotating rod 28. The paraffin microtome for pathological sections also includes a motor 27, which is disposed on the tool holder 8. The output end of the motor 27 is connected to the third rotating rod 28 for transmission.
[0076] In this way, the cutter slices the paraffin wax, and then the rotating plate 29 moves the slices into the collection box 30.
[0077] According to some embodiments of this application, optionally, such as Figure 1 and Figure 2 As shown, the paraffin microtome for pathological sections also includes a collection box 30. A third groove 31 is provided on the base 1, and a third slider 32 is provided on the third groove 31. The collection box 30 is slidably mounted on the base 1 via the third slider 32, and the collection box 30 is positioned relative to the rotating plate 29.
[0078] Thus, the slices are collected by the collection box 30, and the collection box 30 can slide relative to the base 1 by the third slider 32. The extension direction of the third groove 31 is the same as the extension direction of the second groove 9.
