Description

Technical Field

[0001] The present invention belongs to the technical field of slicing and pasting, and specifically relates to a pathological section pasting device for cardiovascular medicine. Background Art

[0002] The cardiology department, that is, the cardiovascular medicine department, is a clinical department set up by the internal medicine departments of hospitals at all levels for the diagnosis and treatment of cardiovascular diseases. The diseases treated include cardiovascular diseases such as coronary heart disease, hypertension, sudden death, arrhythmia, heart failure, cardiomyopathy, myocarditis, and acute myocardial infarction.

[0003] In recent years, the diagnostic demand for pathological medicine has been increasing year by year. Most of the diagnoses in pathological medicine rely on pathological sections for judgment. A pathological section is to take a certain size of diseased tissue, make a pathological section by pathological histology methods, further examine the lesion and the occurrence and development process of the lesion under a microscope, and finally make a pathological diagnosis; the specific steps are sampling, fixation, dehydration and clearing, wax impregnation, embedding, sectioning, pasting, dewaxing, staining, and sealing. The current pasting step mostly relies on manual operation, but manual operation is not precise enough and will also lead to a longer time for pasting pathological sections; moreover, when pasting, the cover glass may be placed offset, and when the offset is large, the pasting position needs to be adjusted, further affecting the work efficiency. Therefore, it is necessary to propose a pathological section pasting device for cardiovascular medicine. Summary of the Invention

[0004] The purpose of the present invention is to propose a pathological section pasting device for cardiovascular medicine. By obtaining the position information of the pathological specimen, judging the deviation distance between the position of the pathological specimen and the cover glass, adjusting the position of the center of the pathological specimen based on this deviation distance, ensuring that the center of the cover glass can accurately and automatically align with the central area of the pathological specimen, and automatically pasting through the pasting part, without manual operation, simplifying the operation process, reducing the offset rate of pasting, and improving the accuracy of pasting.

[0005] To achieve the above purpose, the technical solution of the present invention is as follows: A pathological section pasting device for cardiovascular medicine, including a controller, a base, a glass slide, and a cover glass. A frame in a "冂" shape is fixedly connected to the top of the base. A pasting part is fixedly connected to the upper part of the frame, and a camera is installed on the outer side wall of the pasting part; a first electric push rod is installed inside the pasting part, and the output shaft of the first electric push rod penetrates through the bottom of the pasting part and is provided with a fixing component for fixing the cover glass; An adjusting component is provided on the top of the base. The adjusting component includes a driving part and a supporting part. Both the driving part and the supporting part are fixedly connected to the top of the base, and a plurality of connecting plates are fixedly connected between the driving part and the supporting part; a motor is installed inside the driving part, the output shaft of the motor is coaxially fixedly connected with a screw rod, and the end of the screw rod far away from the motor is rotationally fitted with the side wall of the supporting part; a sliding table is threadedly connected to the screw rod; the controller is used to control the operation of the motor, the first electric push rod, and the camera.

[0006] The above scheme achieves the following principles and beneficial effects: Basic principle: In use, a slide containing the pathological specimen is placed on the slide platform, and a coverslip is placed on the fixing component. At the same time, the camera captures an image of the slide and transmits the image information to the controller. Since the positions of the camera and the mounting part remain unchanged, the controller identifies the center position of the pathological specimen on the slide. Based on this position information, it obtains the deviation distance between the center of the pathological specimen and the coverslip, starts the motor, and drives the screw to rotate. The screw drives the slide platform to move, which in turn moves the slide a certain distance, adjusting the position of the pathological specimen directly below the coverslip to ensure that the center of the coverslip is aligned with the center area of ​​the pathological specimen. Then, the controller activates the first electric actuator, which moves the fixing component and the coverslip downward, so that the coverslip and the slide are attached, completing the mounting process.

[0007] Beneficial effects: 1. This application obtains the position information of the pathological specimen, determines the deviation distance between the position of the pathological specimen and the coverslip, and adjusts the position of the center of the pathological specimen based on the deviation distance to ensure that the center of the coverslip can be accurately and automatically aligned with the center area of ​​the pathological specimen. Automatic mounting is performed through the mounting part without manual operation, which simplifies the operation process, reduces the mounting offset rate, and improves the mounting accuracy.

[0008] 2. This application uses a connecting plate to limit the side wall of the slide table, ensuring that the slide table can move stably when the motor drives the screw to rotate, and reducing interference with the glass slide placed on top of the slide table.

[0009] Furthermore, the fixing component includes a negative pressure section, which is fixedly connected to the output shaft of the first electric actuator. A negative pressure pump is installed inside the negative pressure section, and a controller is used to control the operation of the negative pressure pump. A pipe is fixedly connected to the bottom of the negative pressure section, and the output end of the negative pressure pump is connected to the pipe.

[0010] Beneficial effects: When it is necessary to fix the coverslip, start the negative pressure pump. The negative pressure pump generates negative pressure, and the coverslip is placed at the tube body. The negative pressure at the tube body adsorbs the coverslip. After it is fixed, start the first electric push rod. The first electric push rod drives the negative pressure part and the coverslip to move downward, so that the coverslip is attached to the slide, and the mounting is completed.

[0011] Furthermore, the slide has several cavities, and a locking assembly is vertically slidably fitted inside the cavity; the locking assembly includes a connecting rod, and an elastic layer is sleeved and fixed on the outer wall of the connecting rod; the cover glass has several through holes corresponding to the cavities, and the diameter of the through holes is the same as the diameter of the elastic layer when it expands.

[0012] Beneficial effects: When the coverslip and slide are bonded together, if the negative pressure pump is not turned off, a negative pressure will still exist in the tube. At this time, the negative pressure will draw out the gas between the coverslip and slide through the through hole, reducing the possibility of air bubbles being generated during bonding. Air bubble removal is performed at the same time as bonding. Furthermore, under the suction of this negative pressure, the gas between the elastic layer and the connecting rod is also drawn out, making the elastic layer adhere tightly to the side wall of the connecting rod. Under the continuous suction of the negative pressure, the connecting rod is drawn into the through hole of the coverslip. When the negative pressure pump is turned off, the elastic layer resets according to its own elasticity and contacts and engages with the side wall of the through hole. This can increase the stability of the bonding between the coverslip and slide and also seal the through hole to prevent external gas from entering between the coverslip and slide.

[0013] Furthermore, a limit block is fixedly connected to the bottom of the connecting rod.

[0014] Beneficial effect: Under negative pressure, the connecting rod will be attracted and moved upward. In order to prevent the connecting rod from detaching from the cavity, a limit block is designed at the bottom of the connecting rod. When the connecting rod reaches the top of the cavity, the limit block cannot pass through the top of the cavity, thereby limiting the movement distance of the connecting rod.

[0015] Furthermore, the cover glass also has several oblique holes, which are connected to the through holes.

[0016] Beneficial effect: The oblique holes can increase the negative pressure adsorption area between the cover glass and the slide, thereby improving the efficiency of air bubble removal during the mounting process.

[0017] Furthermore, a hollow conveying section is fixedly connected to the bottom of the horizontal end of the frame. The side wall of the conveying section has a placement opening, and an infrared rangefinder is installed on the side wall of the conveying section away from the placement opening. The conveying section has a passage for conveying coverslips. A transfer section is installed inside the conveying section, and a motor for driving the transfer section is installed on the inner side wall of the conveying section. A controller is used to control the operation of the motor and the infrared rangefinder. A pushing assembly for pushing coverslips is provided on the transfer section. A transfer assembly for transferring coverslips is provided inside the conveying section.

[0018] Beneficial effects: Existing coverslips are made of transparent, thin, and flat glass, which is difficult to handle. When a large number of pathological sections need to be prepared, the operator has to repeatedly pick up and drop the coverslips, resulting in repetitive work and low efficiency. Therefore, a conveying unit is designed. The coverslip is placed on the conveying unit through the placement port. Then, the motor is started, which drives the conveying unit to rotate. When the infrared rangefinder measures that the distance between the coverslip and the transfer component is less than 1 cm, the component is activated, pushing the coverslip to the transfer component. The transfer component then transports the coverslip to the bottom of the tube and fixes it under negative pressure.

[0019] Furthermore, the driving component includes a flexible baffle, which is fixedly connected to the conveying part. Several inclined auxiliary plates are hinged to the side wall of the baffle, and iron blocks are installed inside the auxiliary plates. Several electromagnets for attracting the iron blocks are installed on the side wall of the baffle. A controller is used to control the operation of the electromagnets.

[0020] Beneficial effects: When the cover glass is placed on the conveyor through the placement port, the baffle can limit the two sides of the cover glass, increasing its stability on the conveyor; when the infrared rangefinder measures that the distance between the cover glass and the transfer component is less than 1cm, the electromagnet is activated, and the electromagnet attracts the auxiliary plate, which is attracted and rotates. At this time, the cover glass loses its support and tilts onto the transfer component.

[0021] Furthermore, the conveying section has several locking grooves for limiting the position of the cover glass.

[0022] Beneficial effects: To ensure the stability of the coverslip when it moves on the conveyor, the coverslip can be placed in the locking groove. The locking groove can limit the bottom of the coverslip and improve the stability of the automatic continuous conveying of coverslips.

[0023] Furthermore, the transfer assembly includes a second electric push rod, which is fixedly connected to the inner wall of the conveying section. A push plate is fixedly connected to the output end of the second electric push rod, and a pressure sensor is installed on the top of the push plate. The controller is used to control the operation of the second electric push rod and the pressure sensor.

[0024] Beneficial effects: When the pressure sensor senses the pressure information at the top of the push plate, it transmits the information to the controller. The controller controls the second electric push rod to operate based on the information. The second electric push rod drives the push plate to move through the port to the bottom of the tube.

[0025] Furthermore, a protective layer is fixedly connected to the top of the push plate, and the protective layer is made of elastic material.

[0026] Beneficial effect: When the cover glass slide is tilted onto the push plate, the protective layer on the top of the push plate can buffer the tilting force to a certain extent, preventing damage to the cover glass slide when the push plate is tilted, thus affecting its subsequent use.

[0037] Example 1

[0038] The basic implementation examples are as follows: Figures 1-3 As shown: A pathological section pasting device for cardiovascular medicine department, including a controller, a base 1, a glass slide 15 and a cover glass 16. The model of the controller is preferably SPC-STW-S0402CTR. A frame 2 in a "冂" shape is welded and fixed on the top of the base 1. A pasting part 4 is fixedly connected to the upper part of the frame 2 by bolts. A camera is installed on the outer side wall of the pasting part 4, and the model of the camera is preferably KS-JC. A first electric push rod 13 is installed in the pasting part 4. The output shaft of the first electric push rod 13 penetrates through the bottom of the pasting part 4 and is provided with a fixing component for fixing the cover glass 16. The fixing component includes a negative pressure part 5. The negative pressure part 5 is fixedly connected to the output shaft of the first electric push rod 13 by bolts. A negative pressure pump 7 is installed in the negative pressure part 5, and the model of the negative pressure pump 7 is preferably LP-200V. The controller is used to control the operation of the negative pressure pump 7. The bottom of the negative pressure part 5 is fixedly connected to a pipe body 6 by bolts. The output end of the negative pressure pump 7 is communicated with the pipe body 6. An adjusting component is provided on the top of the base 1. The adjusting component includes a driving part 8 and a supporting part 9. Both the driving part 8 and the supporting part 9 are welded and fixed to the top of the base 1. A plurality of connecting plates 10 are welded and fixed between the driving part 8 and the supporting part 9. A motor 14 is installed in the driving part 8, and the model of the motor 14 is preferably 37GB-3530. The output shaft of the motor 14 is coaxially fixedly connected to a screw rod 11 by bolts. One end of the screw rod 11 away from the motor 14 is rotationally matched with the side wall of the supporting part 9. A sliding table 12 is threadedly connected to the screw rod 11. The controller is used to control the operation of the motor 14, the first electric push rod 13 and the camera.

[0039] Place the glass slide 15 with the pathological specimen on the sliding table 12; fix the cover glass 16 through the fixing component. Specifically: start the negative pressure pump 7, and the negative pressure pump 7 generates negative pressure. At this time, the cover glass 16 can be placed at the bottom of the pipe body 6, and the negative pressure at the pipe body 6 adsorbs and fixes the cover glass 16. At the same time, take a picture of the glass slide 15 through the camera and transmit the image information of the glass slide 15 to the controller. Since the positions of the camera and the pasting part 4 are unchanged, after the controller identifies the central position of the pathological specimen on the glass slide 15, based on this position information, obtain the deviation distance between the center of the pathological specimen and the cover glass 16, start the motor 14, and drive the screw rod 11 to rotate through the motor 14. The screw rod 11 drives the sliding table 12 to move, and then drives the glass slide 15 to move a certain distance to adjust the position of the pathological specimen directly below the cover glass 16 to ensure that the center of the cover glass 16 can be aligned with the central area of the pathological specimen; then the controller starts the first electric push rod 13 again, and the first electric push rod 13 drives the negative pressure part 5 and the cover glass 16 to move downward, so that the cover glass 16 and the glass slide 15 are bonded to complete the pasting.

[0040] Embodiment 2

[0041] The difference between this embodiment and the above embodiment is: as shown in the appendix Figures 4-6As shown, the slide 15 has several cavities, and a locking assembly is vertically slidably fitted inside each cavity. The locking assembly includes a connecting rod 19, and an elastic layer 20 is integrally formed on the outer wall of the connecting rod 19. The cover glass 16 has several through holes 17 corresponding to the cavities, and the diameter of the through holes 17 is the same as the diameter of the elastic layer 20 when it expands. When the cover glass 16 and the slide 15 are attached, if the negative pressure pump 7 is not turned off, there will still be negative pressure in the tube 6. At this time, the negative pressure will draw out the gas between the cover glass 16 and the slide 15 through the through holes 17, reducing the possibility of air bubbles being generated during the mounting process, and performing air bubble removal treatment at the same time as mounting. Furthermore, under the suction of the negative pressure, the gas between the elastic layer 20 and the connecting rod 19 is also drawn out, causing the elastic layer 20 to adhere tightly to the side wall of the connecting rod 19. Under the continuous suction of the negative pressure, the connecting rod 19 will also be drawn into the through hole 17 of the cover glass 16. When the negative pressure pump 7 is turned off, the elastic layer 20 resets according to its own elasticity and contacts and engages with the side wall of the through hole 17. Under the action of the elastic layer 20, the stability of the cover glass 16 and the slide 15 when they are attached can be increased, and the through hole 17 can be sealed to prevent external gas from entering between the cover glass 16 and the slide 15.

[0042] A limiting block 18 is integrally formed at the bottom of the connecting rod 19. Under negative pressure, the connecting rod 19 will be attracted and moved upward. To prevent the connecting rod 19 from detaching from the cavity, a limiting block 18 is designed at the bottom of the connecting rod 19. When the connecting rod 19 reaches the top of the cavity, the limiting block 18 cannot pass through the top of the cavity, thereby limiting the movement distance of the connecting rod 19. Several oblique holes are also opened on the cover glass 16, which are connected to the through hole 17. The oblique holes can increase the negative pressure adsorption area between the cover glass 16 and the glass slide 15, thereby improving the efficiency of air bubble removal during mounting.

[0043] Example 3

[0044] The difference between this embodiment and the above embodiments is as follows: (See attached...) Figures 7-9 As shown, a hollow conveyor section 21 is welded and fixed to the bottom of the horizontal end of the frame 2. The side wall of the conveyor section 21 has a placement opening 23. An infrared rangefinder is installed on the side wall of the conveyor section 21 away from the placement opening 23. The infrared rangefinder is preferably a GLM150C. The conveyor section 21 also has a through opening 22 for conveying the cover glass 16. A transmission section 24 is installed inside the conveyor section 21. A motor for driving the transmission section 24 is installed on the inner side wall of the conveyor section 21. The motor is preferably an R130. A controller is used to control the operation of the motor and the infrared rangefinder. The transmission section 24 in this embodiment has the same structure and principle as the conveyor belt machine mechanism in the prior art.

[0045] The conveying section 24 is equipped with a pushing assembly for pushing the cover glass 16; the pushing assembly includes an elastic baffle 25, which is integrally formed with the conveying section 24. Several inclined auxiliary plates 28 are hinged to the side wall of the baffle 25, and iron blocks are installed inside the auxiliary plates 28; several electromagnets 29 for attracting the iron blocks are installed on the side wall of the baffle 25; a controller is used to control the operation of the electromagnets 29; the conveying section 21 is equipped with a transfer assembly for transferring the cover glass 16. The transfer assembly includes a second electric push rod 27, which is fixedly connected to the inner side wall of the conveying section 21 by bolts. A push plate 26 is welded and fixed to the output end of the second electric push rod 27, and a pressure sensor is installed on the top of the push plate 26. The controller is used to control the operation of the second electric push rod 27 and the pressure sensor.

[0046] The cover glass 16 is placed onto the conveying section 24 through the placement port 23. Then, the motor is started, which drives the conveying section 24 to rotate. When the infrared rangefinder measures that the distance between the cover glass 16 and the push plate 26 is less than 1 cm, the electromagnet 29 is activated. The electromagnet 29 attracts the auxiliary plate 28, which is attracted and rotates. At this time, the cover glass 16 loses the support of the auxiliary plate 28 and tilts onto the push plate 26. When the pressure sensor on the push plate 26 senses the pressure information at the top of the push plate 26, it transmits the information to the controller. The controller controls the second electric push rod 27 to operate based on the information. The second electric push rod 27 drives the push plate 26 to move through the port 22 to the bottom of the tube body 6, and then fixes it with negative pressure.

[0047] The conveying section 24 has several locking grooves for limiting the cover glass slide 16. To ensure the stability of the cover glass slide 16 when moving on the conveying section 24, the cover glass slide 16 can be placed in the locking grooves. The locking grooves can limit the bottom of the cover glass slide 16, improving the stability of the automatic continuous conveying of the cover glass slide 16. The top of the push plate 26 is integrally formed with a protective layer made of elastic material. When the cover glass slide 16 is tilted onto the push plate 26, the protective layer on the top of the push plate 26 can buffer the tilting force to a certain extent, preventing damage to the cover glass slide 16 when the push plate 26 is tilted, thus affecting subsequent use.
