Description

Technical Field

[0001] This invention belongs to the field of paraffin slicing technology, specifically a slicing device and preparation method for paraffin slices of spotted sea bream. Background Technology

[0002] Paraffin section is the most widely used method in routine histological slide preparation techniques. Paraffin sections are not only used to observe the morphology and structure of normal cells and tissues, but are also the main method used in disciplines such as pathology and forensic medicine to study, observe and judge morphological changes in cells and tissues. They are also widely used in research in many other disciplines.

[0003] Spotted sea bream (Oplegnathus punctatus) is highly popular among consumers due to its delicious meat and high nutritional value. As one of the main aquaculture species in deep-sea farming, it is primarily cultivated using a "land-sea relay farming" model. In recent years, domestic scholars have conducted extensive research on gonadal development, digestive system tissue morphology, and pathogen detection and control. However, due to the differences in tissue morphology and structure, living cells or tissues are mostly colorless and transparent, lacking contrast between various tissues and intracellular structures, making them difficult to distinguish clearly under a light microscope. Furthermore, tissues die and decompose quickly after leaving the organism, losing their original normal structure. Therefore, tissues must undergo fixation, paraffin embedding, sectioning, and staining to prevent cell death and ensure clear identification of their morphology and structure. Conventional paraffin sectioning is complex and makes it difficult to guarantee the integrity of experimental samples. Additionally, existing sectioning devices cannot simultaneously cut spotted sea bream paraffin tissue into sections of the same length, reducing the efficiency of research personnel. Based on this, an efficient and convenient paraffin sectioning device was developed to facilitate the observation of the tissue morphology, distribution, and changes of spotted sea bream, laying the groundwork for research on the behavioral and physiological response mechanisms of spotted sea bream.

[0010] Preferably, the fixing member includes a round rod connected to the round groove, and a round plate is provided on the end of the round rod away from the stabilizing box. The round plate and the stabilizing box are connected by a tension spring.

[0011] Preferably, the directional cutting mechanism includes a drive motor mounted on a directional horizontal plate, a worm gear on the output end of the drive motor, the worm gear meshing with a worm, and a directional base on the worm. The worm has a directional pulley, which is connected to a moving pulley via a directional belt. The moving pulley is connected to a first directional rotating shaft. The first directional rotating shaft has a mating pulley, which is connected to a driving pulley on a second directional rotating shaft via a mating belt.

[0012] Preferably, the slicing unit includes a driven helical gear meshing with a directional helical gear. A driven shaft is mounted on the driven helical gear. The driven shaft passes through the inclined plate on the directional horizontal plate and is connected to the directional gear. The directional gear is connected to the driven gear through a directional gear chain. An auxiliary shaft is provided on the driven gear.

The side of the reset plate away from the bottom plate and the side of the directional horizontal plate close to the bottom plate are connected by a reset spring.

[0014] The present invention also provides a method for preparing paraffin slices of spotted sea bream, comprising the above-described apparatus for preparing paraffin slices of spotted sea bream, including the following steps:

[0015] Step 1: The staff places the paraffin wax to be sliced ​​onto the glass carrier and starts the telescopic motor. The output end of the telescopic motor drives the push plate to move. The sliders on both sides of the push plate slide in the grooves on the sides of the groove, which in turn drives the glass carrier on the transmission racks on both sides of the horizontal and vertical plates to move.

[0016] Step 2: When the telescopic motor drives the transmission rack, the transmission rack meshes with the transmission gear, causing the transmission gear to rotate. At the same time, the transmission gear drives the threaded drive shaft to rotate, and the threaded moving blocks move towards each other. The threaded limit block at the bottom of the threaded moving block slides in the limiting groove on the base plate, so that the threaded moving block moves horizontally and stably.

[0017] Step 3: When the transmission rack moves to the maximum distance, the limiting plate on the limiting block moves into the groove on the side of the glass carrier and fixes the glass carrier. At this time, the limiting spring and the elastic rod are in a compressed state, so that the limiting component can stably clamp the glass carrier and improve the stability of the glass carrier when it is sliced ​​by the fixed vector cutting mechanism.

[0018] Step 4: When the stabilizing component secures the glass carrier, the operator starts the drive motor on the directional horizontal plate. The output of the drive motor drives the worm to rotate, which in turn drives the meshing worm to rotate, which in turn drives the directional pulley on the worm to rotate, causing the connecting pulley on the third directional shaft to rotate; thereby causing the directional helical gears at both ends of the worm, the first directional shaft, the second directional shaft, and the third directional shaft to rotate, and the directional helical gears mesh with the moving helical gears to rotate.

[0019] Step 5: The driven shaft causes the directional gear to rotate. The directional gear drives the driven gear to rotate through the directional gear chain, causing the half-ring gear to rotate. The half-ring gear meshes with the moving rack and moves downward. As the moving rack moves downward, it also drives the cutter to move downward.

[0020] Step Six: When the cutter moves downward, the return spring is in a stretched state, which stabilizes the movement and allows the paraffin placed on the glass carrier to be sliced ​​synchronously and in equal quantities, so that the cutter slices the paraffin on the glass carrier into equal lengths. When the half-turn of the half-ring gear is finished, the return spring resets, which in turn drives the cutter to reset, so that the fixed-vector cutting mechanism is reset, waiting for the next time the staff places the paraffin on the glass carrier for a new slicing operation.

[0021] Compared with the prior art, the present invention has the following beneficial effects:

[0022] (1) The staff places the paraffin wax to be sliced ​​on the glass carrier and starts the telescopic motor. The output end of the telescopic motor drives the push plate to move. The sliders on both sides of the push plate slide in the groove provided on the side of the groove, which in turn drives the transmission racks on both sides of the horizontal vertical plate to move. The glass carrier is placed above the transmission racks. The side of the transmission racks is provided with an extension plate. The extension plate is provided with a transmission limit plate, which limits the movement of the transmission racks. Then the glass carrier on which the paraffin wax is placed is moved to the position, so that the fixed vector cutting mechanism slices the paraffin wax into equal segments on the glass carrier, so that each slice of paraffin wax is of equal length, thereby improving the efficiency of the staff's research.

[0023] (2) When the half-circle rotation of the half-ring gear ends, the reset spring resets, which in turn drives the cutter to reset, thus resetting the fixed-vector cutting mechanism, waiting for the next time the staff to place the paraffin on the glass carrier for new slicing work, which further improves the research efficiency.

[0024] (3) The driven shaft causes the directional gear to rotate, and the directional gear drives the driven gear to rotate through the directional gear chain, causing the half ring gear to rotate. The half ring gear meshes with the moving rack and moves downward. At the same time, the moving rack moves downward and drives the cutter to move downward. At this time, the return spring is in a stretched state, which makes the movement stable. Then, the paraffin placed on the glass carrier is sliced ​​synchronously and equally, so that the cutter slices the paraffin on the glass carrier of equal length, thereby improving the research efficiency of researchers.

[0025] (4) When the transmission rack moves to the maximum distance, the limiting plate on the limiting block moves into the groove on the side of the glass carrier and fixes the glass carrier. At this time, the limiting spring and the elastic rod are in a compressed state, so that the four sets of limiting components can stably clamp the glass carrier, improve the stability of the glass carrier, and further enable the fixed vector cutting mechanism to cut the paraffin more accurately, thereby improving the efficiency of the research.

Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments; based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0040] Example 1, by Figures 1 to 10The invention includes a base plate 1 with a groove 2 on it. A telescopic motor 3 is mounted on the groove 2 and connected to a stabilizing component.

A directional vertical plate 22 is provided on the bottom plate 1, and a directional horizontal plate 23 is provided on the directional vertical plate 22. The directional horizontal plate 23 is connected to the directional vector cutting mechanism.

[0041] The staff places the paraffin wax to be sliced ​​onto the glass carrier 32, starts the telescopic motor 3, and the output end of the telescopic motor 3 drives the push plate 4 to move. The sliders 7 on both sides of the push plate 4 slide in the grooves 8 provided on the side of the groove 2, which in turn drives the transmission racks 12 on both sides of the horizontal vertical plate 5 to move. The glass carrier 32 is placed above the transmission racks 12. The side of the transmission racks 12 is provided with an extension plate 19, and the extension plate 19 is provided with a transmission limit plate 21, which limits the movement of the transmission racks 12. Then, the glass carrier 32 containing the paraffin wax is moved to the position, so that the fixed vector cutting mechanism slices the paraffin wax into equal segments on the glass carrier 32, so that each slice of paraffin wax is the same length, which improves the efficiency of the staff's research.

[0042] The transmission mechanism of this embodiment includes a transmission gear 14 meshing with a transmission rack 12. The transmission gear 14 is connected to a threaded drive shaft 15. Both ends of the threaded drive shaft 15 are connected to a transmission base 16. The threaded drive shaft 15 has a first threaded area 17 and a second threaded area 18, with opposite threads at both ends. Limiting components are provided on the first threaded area 17 and the second threaded area 18. The limiting components include threaded moving blocks 24 disposed on the first threaded area 17 and the second threaded area 18. A threaded limiting block 25 is installed on the side of the threaded moving block 24 near the base plate 1. The threaded limiting block 25 is slidably limited by a limiting groove 26 provided on the base plate 1. Side blocks 27 are provided on both sides of the threaded moving block 24. A limiting block 28 is provided on the side of the side block 27 near the transmission rack 12. A spring rod 29 is provided on the limiting block 28. A limiting plate 30 is installed on the spring rod 29. A limiting spring 31 connects the limiting plate 30 and the side block 27. The connection, the limiting plate 30 and the side block 27 are fixedly arranged in conjunction with the grooves 33 on the side of the glass carrier 32 provided on the top surface of the two transmission racks 12; the stabilizing component includes a stabilizing box 34 provided on the telescopic motor 3, a stabilizing pull plate 35 provided on the stabilizing pull plate 35 near the bottom plate 1 and a stabilizing block 36 installed on the side of the stabilizing pull plate 35. The stabilizing block 36 is connected to the stabilizing groove 38 on the stabilizing box 34 and the telescopic fixed block 37 provided on the telescopic motor 3. The side of the stabilizing box 34 away from the bottom plate 1 and the side of the stabilizing pull plate 35 near the bottom plate 1 are connected by a stabilizing spring 39; the stabilizing box 34, the stabilizing block 36 and the telescopic fixed block 37 are provided with a circular groove 40, and the circular groove 40 is connected to the fixing component; the fixing component includes a circular rod 41 connected to the circular groove 40, a circular plate 42 provided on the end of the circular rod 41 away from the stabilizing box 34, and the circular plate 42 is connected to the stabilizing box 34 by a tension spring 43.

[0043] When the telescopic motor 3 drives the slowing rack 12, the slowing rack 12 meshes with the slowing gear 14, causing the slowing gear 14 to rotate. Simultaneously, the slowing gear 14 drives the threaded drive shaft 15 to rotate. The threaded drive shaft 15 has a first threaded area 17 and a second threaded area 18, with opposite threads at both ends. When the threaded drive shaft 15 rotates, it drives the threaded moving blocks 24 on the first threaded area 17 and the second threaded area 18 to move towards each other. The threaded limiting block 25 at the bottom of the threaded moving block 24 slides in the limiting groove 26 on the base plate 1, ensuring the threaded moving block 24 moves horizontally and smoothly. The fixed movement then drives the limiting block 28 on the threaded moving block 24 to move. When the slowing rack 12 moves to the maximum distance, the limiting plate 30 on the limiting block 28 moves into the groove 33 on the side of the glass carrier 32 and fixes the glass carrier 32. At this time, the limiting spring 31 and the elastic rod 29 are in a compressed state, so that the four sets of limiting components can stably clamp the glass carrier 32, improve the stability of the glass carrier 32, and further enable the fixed vector cutting mechanism to cut the paraffin more accurately, thereby improving the efficiency of the research.

[0044] The fixed-vector cutting mechanism of this embodiment includes a drive motor 44 mounted on a directional horizontal plate 23. A turbine 45 is mounted on the output end of the drive motor 44, and the turbine 45 meshes with a worm gear 46. A directional base 47 is mounted on the worm gear 46. A directional pulley 48 is mounted on the worm gear 46, and the directional pulley 48 is connected to a moving pulley 50 via a directional belt 49. The moving pulley 50 is connected to a first directional rotating shaft 51. A mating pulley 52 is mounted on the first directional rotating shaft 51, and the mating pulley 52 is connected to a driving pulley 55 on a second directional rotating shaft 54 ​​via a mating belt 53. A driven pulley 56 is mounted on the second directional rotating shaft 54, and the driven pulley 56 is connected to a connecting pulley 59 on a third directional rotating shaft 58 via a driven belt 57. Directional helical gears 60 are mounted at both ends of the worm gear 46, the first directional rotating shaft 51, the second directional rotating shaft 54, and the third directional rotating shaft 58, and the directional helical gears 60 are connected to the slicing unit. The slicing unit includes a driven helical gear 61 meshing with a directional helical gear 60. A driven shaft 62 is mounted on the driven helical gear 61. The driven shaft 62 passes through a slant plate 63 on a directional horizontal plate 23 and is connected to a directional gear 64. The directional gear 64 is connected to a driven gear 66 via a directional gear chain 65. An auxiliary shaft 67 is provided on the driven gear 66. The auxiliary shaft 67 passes through an auxiliary L-plate 69 on a reset box 68 and is connected to a semi-ring gear 70. The semi-ring gear 70 meshes with a moving rack 71. The side of the moving rack 71 away from the directional horizontal plate 23 is connected to a cutter 72. The reset box 68 has a reset groove 73. Two reset grooves 73 are connected to a reset plate 74. The side of the reset plate 74 away from the directional horizontal plate 23 is connected to a connecting plate 75. The connecting plate 75 is connected to the cutter 72. The side of the reset plate 74 away from the bottom plate 1 and the side of the directional horizontal plate 23 near the bottom plate 1 are connected via a reset spring 76.

[0045] When the stabilizing component secures the glass carrier 32, the operator activates the drive motor 44 on the directional crossbar 23. The output of the drive motor 44 drives the worm gear 45 to rotate, which in turn causes the meshing worm gear 46 to rotate. This, in turn, drives the directional pulley 48 on the worm gear 46 to rotate. Through the engagement of the directional belt 49, the engaging pulley 52 rotates. Simultaneously, the rotation of the engaging pulley 52, via the engagement belt 53, drives the driving pulley 55 on the second directional shaft 54 ​​to rotate, further causing the connecting pulley 59 on the third directional shaft 58 to rotate. This causes the directional helical gears 60 at both ends of the worm gear 46, the first directional shaft 51, the second directional shaft 54, and the third directional shaft 58 to rotate. The directional helical gears 60 mesh with the driving helical gear 61 to rotate, and through the driven shaft 62, the directional gear 64 rotates. The directional gear 64 drives the driven gear 66 to rotate via the directional gear chain 65, causing the semi-ring gear 70 to rotate. The semi-ring gear 70 meshes with the moving rack 71 and moves downward. As the moving rack 71 moves downward, it drives the cutter 72 to move downward. At this time, the return spring 76 is in a stretched state, which stabilizes the movement and allows the paraffin placed on the glass carrier 32 to be sliced ​​synchronously and in equal quantities. This ensures that the cutter 72 slices the paraffin on the glass carrier 32 into equal length slices, thereby improving the research efficiency of researchers. When the semi-ring gear 70 completes half a rotation of the gear mesh, the return spring 76 returns to its original position, which in turn drives the cutter 72 to return to its original position, thus resetting the directional cutting mechanism. It is ready for the next time the staff places the paraffin on the glass carrier 32 for new slicing work, further improving the research efficiency.

[0046] This embodiment provides a method for preparing paraffin slices of spotted sea bream, including the spotted sea bream paraffin slicing apparatus as described above, and comprising the following steps:

[0047] Step 1: The staff places the paraffin wax to be sliced ​​onto the glass carrier 32, starts the telescopic motor 3, and the output end of the telescopic motor 3 drives the push plate 4 to move. The sliders 7 on both sides of the push plate 4 slide in the grooves 8 provided on the side of the groove 2, which in turn drives the glass carrier 32 on the transmission racks 12 on both sides of the horizontal vertical plate 5 to move.

[0048] Step 2: When the telescopic motor 3 drives the transmission rack 12, the transmission rack 12 meshes with the transmission gear 14, causing the transmission gear 14 to rotate. At the same time, the transmission gear 14 drives the threaded drive shaft 15 to rotate, and the threaded moving blocks 24 move towards each other. The threaded limit block 25 at the bottom of the threaded moving block 24 slides in the limiting groove 26 on the base plate 1, so that the threaded moving block 24 moves horizontally and stably.

[0049] Step 3: When the transmission rack 12 moves to the maximum distance, the limiting plate 30 on the limiting block 28 moves into the groove 33 on the side of the glass carrier 32 and fixes the glass carrier 32. At this time, the limiting spring 31 and the elastic rod 29 are in a compressed state, so that the limiting component can stably clamp the glass carrier 32 and improve the stability of the glass carrier 32 when it is sliced ​​by the fixed vector cutting mechanism.

[0050] Step 4: When the stabilizing component secures the glass carrier 32, the operator starts the drive motor 44 on the directional horizontal plate 23. The output end of the drive motor 44 drives the turbine 45 to rotate, which in turn causes the meshing worm 46 to rotate, thereby driving the directional pulley 48 on the worm 46 to rotate, which in turn causes the connecting pulley 59 on the third directional shaft 58 to rotate. This causes the directional helical gears 60 at both ends of the worm 46, the first directional shaft 51, the second directional shaft 54, and the third directional shaft 58 to rotate, and the directional helical gears 60 mesh with the moving helical gear 61 to rotate.

[0051] Step 5: The driven shaft 62 causes the directional gear 64 to rotate. The directional gear 64 drives the driven gear 66 to rotate through the directional gear chain 65, causing the half ring gear 70 to rotate. The half ring gear 70 meshes with the moving rack 71 and moves downward. As the moving rack 71 moves downward, it also drives the cutter 72 to move downward.

[0052] Step Six: When the cutter 72 moves downward, the return spring 76 is in a stretched state, which stabilizes the movement and allows the paraffin placed on the glass carrier 32 to be sliced ​​synchronously and in equal quantities, so that the cutter 72 slices the paraffin on the glass carrier 32 into equal lengths; when the half-turn rotation of the half-ring gear 70 is finished, the return spring 76 resets, which further drives the cutter 72 to reset, so that the fixed-vector cutting mechanism is reset, waiting for the next time the staff places the paraffin on the glass carrier 32 for a new slicing operation.

9. A method for preparing paraffin slices of spotted sea bream, comprising the slicing apparatus for preparing paraffin slices of spotted sea bream as described in claim 8, characterized in that, Including the following steps: Step 1: The staff places the paraffin to be sliced ​​onto the glass carrier (32), starts the telescopic motor (3), and the output end of the telescopic motor (3) drives the push plate (4) to move. The sliders (7) on both sides of the push plate (4) slide in the groove (8) provided on the side of the groove (2), which in turn drives the glass carrier (32) on the transmission rack (12) on both sides of the horizontal vertical plate (5) to move. Step 2: When the telescopic motor (3) drives the transmission rack (12), the transmission rack (12) meshes with the transmission gear (14), causing the transmission gear (14) to rotate. At the same time, the transmission gear (14) drives the threaded drive shaft (15) to rotate, and the threaded moving blocks (24) move towards each other. The threaded limit block (25) provided at the bottom of the threaded moving block (24) slides in the limiting groove (26) on the base plate (1), so that the threaded moving block (24) moves horizontally and stably. Step 3: When the transmission rack (12) moves to the maximum distance, the limiting plate (30) on the limiting block (28) moves into the groove (33) on the side of the glass carrier (32) and fixes the glass carrier (32). At this time, the limiting spring (31) and the elastic rod (29) are in a compressed state, so that the limiting assembly can stably clamp the glass carrier (32) and improve the stability of the glass carrier (32) when it is sliced ​​by the fixed vector cutting mechanism. Step 4: When the stabilizing component stabilizes the glass carrier (32), the operator starts the drive motor (44) on the directional horizontal plate (23). The output end of the drive motor (44) drives the turbine (45) to rotate. The turbine (45) causes the meshing worm (46) to rotate, which in turn drives the directional pulley (48) on the worm (46) to rotate, causing the connecting pulley (59) on the third directional shaft (58) to rotate. This causes the directional helical gears (60) at both ends of the worm (46), the first directional shaft (51), the second directional shaft (54), and the third directional shaft (58) to rotate, and the directional helical gears (61) mesh with the directional helical gears (60) to rotate. Step 5: The driven shaft (62) causes the directional gear (64) to rotate. The directional gear (64) drives the driven gear (66) to rotate through the directional gear chain (65), causing the half ring gear (70) to rotate. The half ring gear (70) meshes with the moving rack (71) and moves downward. At the same time as the moving rack (71) moves downward, it drives the cutter (72) to move downward. Step 6: When the cutter (72) moves down, the reset spring (76) is in a stretched state, which stabilizes the movement and allows the paraffin placed on the glass carrier (32) to be sliced ​​synchronously and in equal amounts, so that the cutter (72) slices the paraffin on the glass carrier (32) into equal lengths; when the half-turn rotation of the half-ring gear (70) ends, the reset spring (76) resets, further driving the cutter (72) to reset, so that the fixed-vector cutting mechanism resets, waiting for the next time the staff will place the paraffin on the glass carrier (32) for a new slicing operation.
