Description

Technical Field

[0001] The invention relates to the technical field of paraffin sections, and in particular to a post-processing device for paraffin sections used in pathology. Background Art

[0002] At present, paraffin section is a commonly used preparation technique in pathology. It makes permanent microscope slide specimens by fixing, dehydrating, transparentizing, waxing, embedding, slicing, staining and sealing tissue samples. This technique is not only used to observe the morphological structure of normal cell tissues, but also the main method for studying, observing and judging the morphological changes of cell tissues in disciplines such as pathology and forensic medicine. Paraffin section can preliminarily judge the nature of tissue lesions, assist clinical diagnosis, and facilitate clinical treatment.

[0003] The processing device for paraffin sections used in pathology is a key tool in pathology research. Its performance and efficiency directly affect the accuracy of diagnostic results and the research process. However, the traditional processing devices currently on the market still show obvious deficiencies in many aspects. First, the lack of automation is a prominent problem. Most of these devices rely on manual operation to fix, transfer and place paraffin slices, which not only increases the burden on staff, but also easily leads to operational errors due to human factors, thus affecting the accuracy of pathological analysis. Secondly, the imperfection of the debris processing mechanism is also a major drawback. If the paraffin debris generated during the slicing process cannot be effectively filtered and collected, it will not only pollute the working environment, but also may interfere with subsequent analysis and reduce the credibility of the diagnosis. Moreover, the positioning accuracy of paraffin slices during transfer and placement needs to be improved. The lack of precise control can easily lead to slice offset and deformation, which will damage the slice quality. Finally, environmental protection and energy-saving considerations should not be ignored. The high energy consumption and potential environmental pollution problems of traditional devices are contrary to the green concept of modern medical equipment. Summary of the invention

[0018] The following will be combined with the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0019] Example 1 like Figure 1 to Figure 11 As shown, a post-processing device for paraffin sections used in pathology includes a main body 10, a wax sheet stretcher 1, a heating auxiliary device 2, and a wax sheet placement device 3. The wax sheet stretcher 1 is installed on the top of the main body 10, the heating auxiliary device 2 is installed inside the main body 10, and the wax sheet placement device 3 is installed on one side of the main body 10; Therefore, the wax sheet stretcher 1 includes a servo motor 11, a negative pressure device 16 and a wax sheet placement block 113. The output end of the servo motor 11 is connected to a coaxially arranged rotating shaft 111 through a coupling. One end of the rotating shaft 111 is fixedly connected to a bent plate 112. The wax sheet placement block 113 is fixedly connected to one end of the bent plate 112. The wax sheet placement block 113 is respectively provided with a first filter 1131 and a second filter 1132. The negative pressure device 16 is fixedly connected to the inside of the main body 10. A negative pressure fan 161 is installed inside the negative pressure device 16. One side of the negative pressure device 16 is fixedly connected to a negative pressure pipe 162. One end of the negative pressure pipe 162 is fixedly connected to one side of the wax sheet stretcher 1.

[0020] like Figure 1 to Figure 6 As shown, a rotating motor 12 is installed internally for rotation of the main body 10, a rotating gear 121 is installed at the output end of the rotating motor 12, a first internal gear 122 is installed internally for rotation of the wax sheet placement block 113, the rotating gear 121 is meshed with the first internal gear 122, the internal sliding assembly of the first internal gear 122 is equipped with four first limiting rods 123 evenly distributed around the circumference, the internal sliding assembly of the main body 10 is equipped with four second limiting rods 124 evenly distributed around the circumference, the tops of the first limiting rods 123 and the second limiting rods 124 are commonly connected to a corner fixing block 125, a micro motor 1251 is installed on one side of the corner fixing block 125, and a clamping plate 1252 is installed at the output end of the micro motor 1251.

[0021] like Figure 1 to Figure 10 As shown, the heating auxiliary device 2 includes a first cylinder 21 and a heating frame 22. The first cylinder 21 is installed inside the main body 10, and the heating frame 22 is installed at the output end of the first cylinder 21. A heater 25 is installed at the bottom of the heating frame 22, and a temperature sensor 26 is installed on the inner wall of the heating frame 22. The bottom of the heating frame 22 is respectively fixedly connected with a water supply pipe 23 and a water outlet pipe 24.

[0022] like Figure 1 to Figure 6 As shown, the first internal gear 122 is provided with four circumferentially evenly distributed "C"-shaped through grooves, and the four first limiting rods 123 are respectively slidably assembled inside the four through grooves. The inside of the main body 10 is provided with four symmetrically arranged sliding limiting grooves, and the four second limiting rods 124 are respectively slidably assembled inside the four limiting grooves.

[0023] In this embodiment, when the device is used, the servo motor 11 is first turned on. The servo motor 11 is started to rotate the rotating shaft 111. The rotation of the rotating shaft 111 causes the bending plate 112 to rotate at an angle, so that the wax sheet placement block 113 is angled, so that the wax sheet placement block 113 and the cut paraffin sheet are fitted together, and the negative pressure fan 161 is started simultaneously. The start of the negative pressure fan 161 applies negative pressure to the wax sheet placement block 113 through the negative pressure pipe 162, so that the wax sheet placement block 113 preliminarily fixes the paraffin sheet. During the fixation of the paraffin sheet, the filter size of the first filter 1131 is larger than the debris on the paraffin sheet, and the paraffin sheet is fixed during the fixation of the paraffin sheet. The paraffin debris on the wax sheet is sent to the second filter screen 1132. The filter size of the second filter screen 1132 is smaller than the debris on the paraffin sheet, and the paraffin debris is collected. Then the servo motor 11 is turned on to rotate, so that the wax sheet placement block 113 is separated from the wax sheet cutting device. After the separation is completed, the micro motor 1251 is turned on. The start of the micro motor 1251 enables the clamping plate 1252 to clamp and fix the four corners of the paraffin sheet. Then the start of the servo motor 11 enables the wax sheet placement block 113 to be sent to the top of the heating frame 22. At this time, the first cylinder 21 is turned on. The start of the first cylinder 21 causes the heating frame 22 to slide. The sliding of the heating frame 22 causes the wax sheet placement block 113 to enter The inside of the heating frame 22 is heated. At this time, the temperature inside the heating frame 22 is kept at about 45 degrees because of the heater 25 and the temperature sensor 26 (the temperature sensor 26 transmits the heat signal inside the heating frame 22 to the external controller, and the external controller controls the heater 25 in real time after receiving the heat signal). After the wax sheet placement frame is heated for a period of time, the rotating motor 12 inside the main body 10 is turned on. The rotating motor 12 starts to rotate the rotating gear 121, and the rotating gear 121 is engaged with the first internal gear 122 to rotate the first internal gear 122. During the rotation of the gear 122, the first limit rod 123 and the second limit rod 124 slide following the positions of the through groove and the limit groove, so that the four corner fixing blocks 125 slide toward the outside of the four corners of the wax sheet placement block 113 respectively, and the four corners slide synchronously, so that the four corners of the paraffin sheet are pulled evenly, and the paraffin sheet is unfolded. The servo motor 11 drives the rotating shaft 111 and the bending plate 112 to achieve precise angle adjustment of the wax sheet placement block 113, which fits tightly with the cut paraffin sheet. The use of the negative pressure fan 161 generates negative pressure on the wax sheet placement block 113 through the negative pressure tube 162, which effectively and preliminarily fixes the paraffin sheet and improves work efficiency.

[0024] Example 2 like Figure 1 to Figure 9As shown, a connecting frame 15 is fixedly connected to the inside of the main body 10, a driving motor 151 is installed at the bottom of the connecting frame 15, a protrusion 152 is installed at the output end of the driving motor 151, a plurality of circumferentially evenly distributed meshing gears 153 are rotatably installed inside the connecting frame 15, a closing plate 154 is fixedly connected to the bottom of the meshing gear 153, a plurality of circumferentially evenly distributed auxiliary balls 155 are rotatably installed inside the connecting frame 15, a second internal gear 14 is rotatably installed inside the connecting frame 15, a plurality of meshing gears 153 are all meshed with the second internal gear 14, an inner groove limit plate 141 is fixedly connected to one side of the second internal gear 14, and the protrusion 152 is slidably assembled inside the inner groove limit plate 141.

[0025] like Figure 1 to Figure 11 As shown, the wax sheet placer 3 includes an angle motor 31 and a glass slide placing plate 36. The angle motor 31 is installed on the top of the main body 10. A rotating plate 32 is installed at the output end of the angle motor 31. A second cylinder 33 is installed on the top of the rotating plate 32. A temporary storage plate 34 is installed at the output end of the second cylinder 33. Four circumferentially evenly distributed negative pressure suction heads 35 are installed on the temporary storage plate 34. The glass slide placing plate 36 is fixedly connected to one side of the main body 10. A glass slide body 37 is arranged on the top of the main body 10.

[0026] like Figure 1 to Figure 9 As shown, the plurality of closing plates 154 are in the shape of a semicircular teardrop with a sharper head and a thicker tail. When unfolded, the plurality of closing plates 154 fit together to form a partition between the main body 10 and the negative pressure tube 162 .

[0027] like Figure 1 to Figure 6 As shown, a rotating motor 13 is installed inside the wax sheet placement block 113 , and an output end of the rotating motor 13 is connected to a coaxially arranged straight shaft 131 through a coupling, and a dirt removal plate 132 is fixedly sleeved on the outer peripheral surface of the straight shaft 131 .

[0028] In this embodiment, based on the same concept as in embodiment 1, before the wax sheet placement block 113 performs negative pressure fixing on the paraffin sheet, the drive motor 151 can be turned on. The start of the drive motor 151 causes the protrusion 152 to rotate, and the protrusion 152 slides in the inner groove limit plate 141, causing the position of the inner groove limit plate 141 to slide, thereby causing the inner circular gear to rotate. The second inner gear 14 rotates by rotating with a plurality of meshing gears 153. The rotation of the meshing gear 153 causes the closing plate 154 to rotate. The rotation of the closing plate 154 causes the negative pressure wind force inside the main body 10 to be adjusted. When the second inner gear 14 rotates, an auxiliary ball 155 assists in the rotation. After the paraffin sheet is extended, the first cylinder 21 is turned on for reset. After the reset is completed, the micro motor 1251 is restarted, and the clamping plate 1252 releases the paraffin sheet. After the release is completed, the negative pressure fan 161 is turned off, and the angle motor 31 is turned on first to cause the rotating plate 32 to rotate the placement block 1 13, then the second cylinder 33 is started, so that the four negative pressure suction heads 35 on the rotating plate 32 touch the four corners of the paraffin sheet, and then the negative pressure suction heads 35 extract the paraffin sheet. After the extraction is completed, the second cylinder 33 is turned on to reset. After the reset is completed, the angle motor 31 is turned on to send the rotating plate 32 to the top of the glass slide placement plate 36, and then the second cylinder 33 is turned on again to make the paraffin sheet touch the glass slide body 37, and then the negative pressure suction heads 35 are released to place the paraffin sheet on the glass slide body. After placement on the wafer carrier body 37, the angle motor 31 and the second cylinder 33 are reset. At this time, the servo motor 11 and the rotating motor 13 are started synchronously. The start of the servo motor 11 causes the wax wafer placement block 113 to rotate at an angle. At this time, the rotation of the rotating motor 13 causes the straight shaft 131 to rotate. The rotation of the straight shaft 131 causes the dirt drop plate 132 to open. The opening of the dirt drop plate 132 causes the paraffin debris and water inside the main body 10 to fall due to gravity, thereby improving the functionality of the equipment.

[0029] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
