Description
Technical Field
[0001] The utility model relates to the technical field of paraffin sectioning, in particular to a tissue wax block sectioning device with a water soaking function. Background Art
[0002] Paraffin section is the most widely used method in the routine histological preparation technology. Paraffin sections are not only used to observe the morphological structure of normal cell tissues, but also the main method for disciplines such as pathology and forensic medicine to study, observe and judge the morphological changes of cell tissues, and have also been quite widely used in the research of many other disciplinary fields. In teaching, most of the section specimens observed under a light microscope are prepared by the paraffin section method. Living cells or tissues are mostly colorless and transparent, and there is a lack of contrast between various tissues and between various structures within cells, making it difficult to clearly distinguish them under a general light microscope; tissues will quickly die and undergo tissue decay after leaving the body, losing their original normal structure. Therefore, tissues need to go through steps such as fixation, paraffin embedding, sectioning, and staining to prevent cell tissue death and enable clear identification of their morphological structure.
[0003] Existing paraffin sectioning usually uses a paraffin sectioning machine, which generally consists of a main body, a stage, a sectioning knife, a hardness adjustment device, a cutting thickness adjustment, and an operating system, etc. The main body is the core part of the entire device, including components such as a motor, a cutting tool, a cutting system, and a lubrication system. The stage is the carrier for cutting samples, usually made of steel plate, with a smooth surface and can accommodate samples of different sizes. The sectioning knife is driven to rotate by the main body and usually consists of a blade and a knife rod, making the cutting more precise and stable. The hardness adjustment device can adjust the force between the sectioning knife and the cutting part according to the properties of the sample to ensure the stability and quality during cutting. The cutting thickness adjustment is achieved by adjusting the angle or other mechanical means, and the appropriate cutting thickness of the sample can be adjusted. The operating system can conveniently control the operation of the device and monitor the usage situation of the device.
[0004] After the existing paraffin sectioning machine slices paraffin, the qualified and unqualified paraffin thin slices are mixed together. At the same time, the paraffin thin slices are in a wrinkled and curled state, making it difficult and laborious for workers to identify them with the naked eye, and the accuracy is difficult to guarantee, affecting subsequent use. Summary of the Utility Model
[0005] In view of this, the purpose of the utility model is to provide a tissue wax block sectioning device with a water soaking function to solve the problem that after the existing paraffin sectioning machine slices paraffin, the qualified and unqualified paraffin thin slices are mixed together, and at the same time, the paraffin thin slices are in a wrinkled and curled state, making it difficult and laborious for workers to identify them with the naked eye, and the accuracy is difficult to guarantee, affecting subsequent use.
[0006] The utility model solves the above technical problems through the following technical means:
[0007] A tissue wax block slicing device with a soaking function, comprising a workbench and a paraffin slicing machine arranged on the workbench. A crawler-type carrier is arranged on the paraffin slicing machine. A camera is arranged on the workbench opposite to the crawler-type carrier. An electrostatic generator for discharging the crawler-type carrier is arranged on one side of the workbench with respect to the crawler-type carrier. The crawler-type carrier includes a crawler body and a driving component for driving the rotation of the crawler body. It also includes an image recognition system, and the camera is electrically connected to the image recognition system.
[0008] Furthermore, the crawler body includes a plurality of alternately distributed adsorption blocks and connection blocks. An installation sleeve is arranged on one side of the workbench with respect to the crawler body. One end of the electrostatic emission rod of the electrostatic generator is located inside the installation sleeve, and the other end extends out of the installation sleeve and faces the crawler body. A contact head for contacting the electrostatic emission rod is arranged on the adsorption block.
[0009] Furthermore, the electrostatic emission rod is slidably matched with the installation sleeve. A spring is arranged between the electrostatic emission rod and the inner wall of the installation sleeve, and both ends of the spring are fixedly connected to the electrostatic generation rod and the inner wall of the installation sleeve respectively.
[0010] Furthermore, an electrostatic protection sleeve is sleeved on the surface of the connection block.
[0011] Furthermore, a water tank and a transfer rod are arranged on the workbench. The water tank is located on one side of the paraffin slicing machine. The transfer rod is used to transfer the qualified paraffin thin slices on the crawler body into the water tank.
[0012] Furthermore, a first electrostatic eliminator and a power component are arranged on the workbench. The first electrostatic eliminator is used to eliminate the static electricity of the crawler body. The power component is used to drive the movement of the transfer rod. The power component includes a rotary motor and a rotating rod. The rotating rod is vertically arranged. The rotary motor is fixedly installed on the workbench. The bottom end of the rotating rod is fixedly connected to the output end of the rotary motor. One end of the transfer rod is fixedly connected to the top end of the rotating rod, and the other end extends horizontally to form a suspended end.
[0013] Furthermore, the transfer rod is electrically connected to the electrostatic generator.
[0014] Furthermore, a second electrostatic eliminator is arranged on the workbench. The second electrostatic eliminator is used to eliminate the static electricity on the transfer rod.
[0015] Furthermore, a collection box is arranged at the bottom of the paraffin slicing machine with respect to the crawler-type carrier. A scraping blade is arranged in the collection box, and the scraping blade contacts the surface of the bottom of the crawler body.
[0016] Advantages of the present utility model: During operation, the paraffin slicer slices the paraffin block to obtain paraffin thin slices. One end of the paraffin thin slice is located on the crawler-type carrier, and the other end adheres to the cutting edge of the cutting blade. The crawler-type carrier generates static electricity through the static electricity generator to adhere to the paraffin thin slice. The driving component drives the crawler body to rotate to pull the curled paraffin thin slice, so that it is displayed relatively flatly under the camera. At this time, the camera takes a picture and transmits the picture to the image recognition system. This image recognition system judges the picture to determine whether it is qualified, effectively avoiding the problem of mixing qualified and unqualified paraffin thin slices together.

Therefore, the terms describing the positional relationship in the drawings are only for illustrative purposes and cannot be understood as a limitation to the present utility model. For those of ordinary skill in the art, the specific meanings of the above terms can be understood according to specific circumstances.
[0025] As Figures 1-4 shown, a tissue wax block slicing device with a soaking function according to the present utility model includes a workbench 1 and a paraffin slicing machine 2 disposed on the workbench 1. A crawler-type carrier is inclinedly disposed on the paraffin slicing machine 2. A camera 5 is disposed on the workbench 1 facing the upper surface of the carrier. An electrostatic generator 4 for discharging the crawler-type carrier is disposed on the workbench 1 on the left side of the crawler-type carrier. The crawler-type carrier includes a crawler body 3 and a drive assembly for driving the crawler body 3 to rotate. It further includes an image recognition system, and the camera 5 is electrically connected to the image recognition system.
[0026] In this embodiment, the camera 5 is installed on the upper surface of the workbench 1 through a support frame. The camera 5 can take pictures of the cut paraffin sections and transmit the image information to the image recognition system. After training, the image recognition system can accurately distinguish good and available sections from unavailable sections. In fact, the driving component can be the driving roller 21, the driven roller 22 and the crank. The driving roller 21 and the driven roller 22 are installed at both ends of the crawler body 3 and are in meshing transmission with the crawler body 3. One end of the crank is fixedly connected to one end of the driving roller 21. By rotating the crank, the driving roller 21, the driven roller 22 and the crawler body 3 can be driven to rotate. In this embodiment, the driving component includes the driving roller 21, the driven roller 22 and the driving motor 13. The driving roller 21 and the driven roller 22 are installed at both ends of the crawler body 3 and are in meshing transmission with the inner side of the crawler body 3. Both ends of the driving roller 21 and the driven roller 22 extend outside the crawler body 3. Support plates 12 are respectively arranged on the paraffin slicer 2 at both ends of the driving roller 21 and the driven roller 22. The driving roller 21 and the driven roller 22 are respectively rotatably installed on the support plates 12 to support the crawler body 3 and make the crawler body 3 in a suspended state. One end of the driving roller 21 passes through the support and is fixedly connected to the output end of the driving motor 13. With such a structural design, when the driving motor 13 rotates, the driving roller 21, the driven roller 22 and the crawler body 3 can be driven to rotate. The steel plate carrier of the traditional paraffin slicer 2 is set to be crawler type so that it can rotate, and then the static generator 4 is used to make it carry static electricity to adhere to the paraffin sections. In this way, when the crawler body 3 rotates, the paraffin sections can be pulled and straightened, which is convenient for the camera 5 to accurately capture their image information.
[0027] The crawler body 3 includes a plurality of alternately distributed adsorption blocks 31 and connection blocks 32. The outer surfaces of the adsorption blocks 31 and the connection blocks 32 are flush to form a carrier. An installation sleeve 6 is arranged on the workbench 1 between the crawler body 3 and the static generator 4. The installation sleeve 6 is fixed on the workbench 1 through a support rod 11. One end of the static emission rod of the static generator 4 is slidably connected in the installation sleeve 6, and the other end extends outside the installation sleeve 6 and faces the crawler body 3. One end of the adsorption block 31 close to the static emission rod is integrally formed with a contact head 311 for contacting the static emission rod. In this embodiment, the contact head 311 is hemispherical. One end of the static emission rod facing the crawler body 3 is integrally formed with a hemispherical rod head. With such a structural design, when the crawler body 3 rotates, the contact head 311 is in good contact with the static emission rod and does not affect the rotation of the crawler body 3. A spring 7 is arranged between the static emission rod and the inner wall of the installation sleeve 6. Both ends of the spring 7 are fixedly connected to the static generation rod and the inner wall of the installation sleeve 6 respectively. With such a structural design, when the crawler body 3 rotates and the adsorption block 31 rotates to the position of the static emission rod, the contact head 311 contacts the static emission rod, and the adsorption block 31 can carry static electricity to adsorb the paraffin sections. At the same time, the spring 7 can ensure that each adsorption block 31 rotating to the position of the static emission rod can contact the static emission rod.
[0028] The surface of the connecting block 32 is sleeved with an electrostatic protection sleeve, so that the connecting block 32 is always free of static electricity.
[0029] In the above embodiment, the adsorption block 31 can be made of an iron block, and the connecting block 32 can be made of an iron block, plastic, etc. Since the size of the existing tissue wax slices is usually (1*1) cm 2 , (1*2) cm 2 or (2*2) cm 2 , therefore, the sizes of the adsorption block 31 and the connecting block 32 can be designed according to actual needs. In this embodiment, the width of the adsorption block 31 is 1-3 mm, the thickness is 2 mm, the width of the connecting block 32 is 17-19 mm, and the thickness is 2 mm. With such a structural design, the combination of one adsorption block 31 and one connecting block 32 can just adsorb the length of a paraffin thin slice, avoiding the whole paraffin thin slice being adsorbed on the surface of the track body 3, which is beneficial to the accuracy of image information and convenient for transferring the paraffin thin slice from the track body 3 to the water tank 8.
[0030] A water tank 8 and a transfer rod 9 are arranged on the workbench 1. The water tank 8 is located on the right side of the paraffin slicer 2. The transfer rod 9 is used to transfer the qualified paraffin thin slices on the track body 3 into the water tank 8. The transfer rod 9 is located at the front end of the paraffin slicer 2.
[0031] A first static eliminator (not shown in the figure) and a power assembly are arranged on the workbench 1. The first static eliminator is used to eliminate the static electricity of the track body 3. In this embodiment, the elimination range of the first static eliminator covers the area of the track-type workbench 1. An arc-shaped static eliminator can be used to surround the area of the track-type workbench 1, or a contact-type static eliminator can be used and installed on the right side of the track body 3. By turning on or off the first static eliminator, the static electricity of the adsorption block 31 on the track body 3 can be effectively eliminated, so that it no longer adheres to the paraffin thin slice. The static electricity of the adsorption block 31 can also be eliminated by moving the first static eliminator closer to or farther away from the track body 3. The power assembly is used to drive the transfer rod 9 to move. The power assembly includes a rotating motor 14 and a rotating rod 16. The rotating rod 16 is vertically arranged. The rotating motor 14 is fixedly installed on the workbench 1 by bolts. An installation plate 15 with an L-shaped cross section is arranged on the workbench 1 at the position of the rotating motor 14. The bottom end of the rotating rod 16 is fixedly connected to the output end of the rotating motor 14. The top end of the rotating rod 16 passes through the installation plate 15 and is rotatably connected to the installation plate 15 through a bearing. One end of the transfer rod 9 is fixedly connected to the top end of the rotating rod 16, and the other end extends horizontally to form a suspended end. The height of the transfer rod 9 is just at the corresponding position of the track body 3. The suspended end of the transfer rod 9 is used to adsorb the paraffin thin slice for transfer. With such a structural design, when the rotating motor 14 rotates, it drives the transfer rod 9 to rotate, and the transfer rod 9 can reciprocate on the surface of the track body 3 and above the water tank 8.
[0032] The transfer rod 9 is electrically connected to the electrostatic generator 4. The electrostatic generator 4 can make the transfer rod 9 charged electrostatically so that it can adsorb the paraffin flakes. A second static eliminator 17 is provided on the workbench 1. The second static eliminator 17 is used to eliminate the static electricity on the transfer rod 9. In this embodiment, the second static eliminator 17 is arc-shaped and installed at the position of the water tank 8.
[0033] The paraffin slicer 2 is provided with a collection box 18 at the bottom of the crawler-type carrier. A scraping blade is provided in the collection box 18. The scraping blade contacts the surface of the bottom of the crawler body 3. The collection box 18 is used to collect unqualified sections. The scraping blade can scrape the unqualified sections from the crawler body 3 and make them fall into the collection box 18.
[0034] In the above embodiment, a control system is further included. The electrostatic generator 4, the first static eliminator, the second static eliminator 17, the camera 5, the drive motor 13, and the rotation motor 14 are all electrically connected to the control system.
[0035] Working principle:
[0036] During slicing, starting from the up-and-down and forward movement of the specimen clamp 19 of the paraffin slicer 2, the crawler body 3 starts to roll and the electrostatic generator 4 is turned on. The rolling speed of the crawler body 3 is synchronized with the moving speed of the specimen clamp 19. After the specimen wax block contacts the blade, each time it moves up and down, the blade will cut out a thin slice from the specimen wax block. When the paraffin contacts the adsorption block 31, it will be adhered electrostatically and then rotate with the crawler body 3. The thin slice is pulled. At this time, the camera 5 takes a picture and transmits the image information to the image recognition system for judgment. If the thin slice is unqualified after being pulled, the crawler body 3 will carry the thin slice to the bottom and discard it. Specifically, the scraper 20 scrapes off the unqualified paraffin thin slices and makes them fall into the collection box 18. If it is judged that the thin slice is qualified after being pulled, the crawler body 3 and the specimen clamp 19 will immediately stop moving. The electrostatic generator 4 disconnects the discharge to the crawler body 3, and the first static eliminator is turned on to eliminate the static electricity on the adsorption block 31 so that it no longer adsorbs the paraffin thin slices. Then the first static eliminator is disconnected, and the transfer rod 9 is driven to rotate by the rotation motor 14. The transfer rod 9 can reciprocate between the crawler and the water tank 8. The transfer rod 9 is connected to the electrostatic generator 4, and the rod head of the transfer rod 9 is charged electrostatically. When the paraffin thin slice is qualified and the crawler body 3 stops moving, the transfer rod 9 immediately rotates to the position of the crawler body 3 and contacts the paraffin thin slice. The paraffin thin slice is adsorbed on the transfer rod 9 due to static electricity. Subsequently, the transfer rod 9 rotates to the position of the water tank 8. Since the second static eliminator 17 is provided at the position of the water tank 8, when the transfer rod 9 moves above the water tank 8, the static electricity is eliminated and the paraffin thin slice falls into the water tank 8.
[0037] The tissue wax block slicing device provided by the present utility model can accurately judge and distinguish qualified and unqualified paraffin thin slices, and automatically transfer the qualified paraffin thin slices into the water tank 8, with high automation degree, greatly accelerating the manufacturing efficiency of paraffin thin slices and reducing the labor intensity of staff.
