Description

Technical Field

[0001] This utility model relates to the field of slicing equipment technology, specifically a paraffin slicer with a cutting mark structure. Background Technology

[0002] A paraffin microtome with cutting markers is a precision instrument used in biomedical research and pathological analysis. It is primarily used to cut paraffin-embedded tissue samples into thin sections for microscopic observation and analysis. The existing technology is authorized under publication number CN 222003643. U's patent discloses an adjustable paraffin microtome, including a body with a longitudinal drive structure for adjusting the position of the paraffin sections. At one end of the body opposite the longitudinal drive structure is a section thickness adjustment mechanism for adjusting the thickness of the paraffin sections. The section thickness adjustment mechanism includes a lifting screw, a stepper motor connected to the top of the lifting screw, and a lifting screw slider. While this device can adjust the section thickness of paraffin blocks during use, it lacks marking on the paraffin blocks. This makes it difficult to record and trace specific information about the sections (such as position, thickness, and order). Markings can serve as reference points to help pathologists or researchers quickly locate areas of interest. Without markings, there are no obvious reference points on the sections during subsequent microscopic observation and analysis. Pathologists or researchers need to spend more time and effort to find specific tissue areas, increasing the complexity and difficulty of the operation and reducing the accuracy of diagnostic or research results. Therefore, we propose a paraffin microtome with a cutting marking structure. Utility Model Content

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0018] Please see Figure 1-8 This embodiment provides a technical solution: a paraffin slicer with a cutting mark structure, including a machine body 1, a mounting base 3 is provided on the front side of the bottom wall of the machine body 1, a blade 4 is provided on the rear side of the upper end of the mounting base 3, a connecting base 10 is provided in the middle of the front end of the machine body 1, a protective box 26 is provided on the front side of the upper end of the machine body 1, and a marking mechanism 5 is also included. Marking mechanism 5 includes a mounting rod 51, a drive plate 52, and a cutting assembly 56. The mounting rod 51 is rotatably connected to the middle of the bottom wall of the protective box 26. The drive plate 52 is provided on the lower side of the outer arc surface of the mounting rod 51. The cutting assembly 56 is located inside the protective box 26 and is driven by the drive plate 52. During the rotation of the drive device, the drive plate 52 is rotated through the mounting rod 51, thereby causing the drive plate 52 to move the cutting assembly 56. Through the cooperation of the drive plate 52 and the adjusting rod 564, the positions of the first marking blade 562 and the second marking blade 563 can be adjusted, so as to mark the paraffin block according to the actual situation. The marking can record the slicing information of the paraffin block, and the position, thickness, and order of the slices can be determined based on the marking, ensuring the accuracy of subsequent diagnostic or research results.

[0019] It also includes a controller 2 and control switches 27. The controller 2 is located at the front end of the body 1, and the control switches 27 are respectively located on the left side of the front end of the body 1. The input terminal of the controller 2 is electrically connected to the external power supply. The two sets of control switches 27 are connected in series between the input terminal of the controller 2 and the output terminal of the external power supply, which can regulate the electrical components inside the equipment.

[0020] The marking mechanism 5 includes a servo motor 53, a worm gear 54, a worm wheel 55, and a potentiometer 57. The servo motor 53 is located on the left side of the front end of the protective housing 26. The worm gear 54 is located at the rear end of the output shaft of the servo motor 53. The worm wheel 55 is located on the upper side of the outer arc surface of the mounting rod 51, and the worm gear 54 and worm wheel 55 are meshed together. The potentiometer 57 is located in the middle of the upper end of the protective housing 26. The probe at the lower end of the potentiometer 57 is fixedly connected to the upper end of the mounting rod 51. The input end of the servo motor 53 is electrically connected to the output end of the controller 2. The potentiometer 57 is bidirectionally electrically connected to the controller 2. The output shaft of the servo motor 53 drives the worm gear 54 to rotate. During rotation, the worm gear 54 drives the worm wheel 55 to rotate through meshing. During rotation, the worm wheel 55 drives the drive plate 52 to rotate through the mounting rod 51. During the process, the mounting rod 51 also drives the probe of potentiometer 57 to rotate, which in turn drives the sliding contact inside potentiometer 57 to rotate. At this time, the position of the sliding contact on the resistive body changes. When the sliding contact moves on the resistive body, the resistance value between the sliding contact and the two fixed terminals changes. Then, potentiometer 57 detects the changed resistance value through its internal detection element. Finally, potentiometer 57 calculates the rotation angle of drive board 52 based on the known relationship between resistance value and angle. Afterward, potentiometer 57 transmits the detected information to controller 2 through its built-in data transmission module. Controller 2 receives the detected data through its built-in serial communication port. When drive board 52 rotates 90°, it means that marking blade 2 563 extends to the designated position, while marking blade 1 562 retracts into the designated position.

[0021] The cutting component 56 includes a fixed rod 561, a first marking blade 562, a second marking blade 563, and an adjusting rod 564. The fixed rod 561 is slidably connected to the clearance holes on the left and right sides of the rear end of the protective box 26. The rear ends of the left and right fixed rods 561 are respectively provided with the second marking blade 563 and the first marking blade 562. The front side of the outer arc surface of the two fixed rods 561 is provided with the adjusting rod 564. The left and right ends of the drive plate 52 are provided with adjusting grooves. The adjusting rods 564 are respectively located in the vertically adjacent adjusting grooves. The drive device adjusts the position of the protective box 26 until the second marking blade 563 is aligned with the marking area of ​​the upper left corner of the paraffin block. The second marking blade 563 cuts off a part of the upper left corner of the paraffin block to mark it. The marking can record the slicing information of the paraffin block.

[0022] The machine body 1 has two guide slide pillars 6 on its upper side. The front ends of the two guide slide pillars 6 are slidably connected to the sliding holes on the left and right sides of the rear end of the connecting plate 7. A slide pillar 8 is slidably connected in the guide slide hole in the middle of the upper end of the connecting plate 7. A fixing plate 9 is set in the middle of the lower end of the slide pillar 8. A drive groove is set in the middle of the right end of the fixing plate 9. The fixing plate 9 is located in the connecting groove in the middle of the front end of the machine body 1. A connecting seat 10 is set at the front end of the fixing plate 9. An electric push rod 11 is set in the middle of the rear wall of the machine body 1. The front end of the telescopic end of the electric push rod 11 is fixedly connected to the middle of the rear end of the connecting plate 7. A laser rangefinder 12 is set on the right side of the rear wall of the machine body 1. The laser rangefinder 12 corresponds to the front and rear position of the connecting plate 7. The laser rangefinder 12 is located between the right side of the electric push rod 11 and the left side of the outer arc surface of the guide slide pillar 6 on the right side. The electric push rod 11 is connected to the control... The output of controller 2 is electrically connected, and the laser rangefinder 12 is bidirectionally electrically connected to controller 2. Through the control of controller 2, the electric push rod 11 starts to operate. The telescopic end of the electric push rod 11 extends, thereby causing the electric push rod 11 to drive the sliding column 8 forward through the connecting plate 7 (during the movement of the connecting plate 7, the guide sliding column 6 provides a guiding support, reducing the radial force applied by the connecting plate 7 to the electric push rod 11, preventing the telescopic end of the electric push rod 11 from bending and deforming. The radial force of the electric push rod 11 is borne by the sliding of the guide sliding column 6, and the electric push rod 11 is only subjected to the front and rear axial forces). The sliding column 8 will drive the connecting seat 10 forward through the fixing plate 9, thereby causing the connecting seat 10 to drive the paraffin block forward through the clamp. When the distance between the front end of the laser rangefinder 12 and the rear end of the connecting plate 7 is equal to g, it means that the paraffin block has moved to the designated position.

[0023] The machine body 1 has a central wheel 13 rotatably connected to its right front end. A drive rod 14 is located at the left edge of the central wheel 13, with its left end inside the drive groove. An operating rod 16 is rotatably connected to the right edge of the central wheel 13. A pressure sensor 15 is located on the upper side of the front wall of the machine body 1. The lower end of the pressure sensor 15 probe contacts the upper end of the fixed plate 9. The pressure sensor 15 is bidirectionally electrically connected to the controller 2. The operator rotates the operating rod 16, which in turn drives the drive rod 14 to rotate via the central wheel 13. The central axis of the drive rod 14 is different from that of the central wheel 13, so the drive rod 14 will have lateral and vertical displacements during rotation. During the rotation of the drive rod 14, the drive rod 14 will slide inside the drive groove and rotate relative to the drive groove. When the drive rod 14 rotates downward, the drive rod 14 will drive the connecting seat 10 to move downward through the fixed plate 9. The connecting seat 10 will drive the paraffin block to move downward through the clamp. During the movement of the paraffin block, the blade 4 will contact the paraffin block, thereby slicing the paraffin block.

[0024] Among them: an electric push rod 17 is installed in the mounting groove on the lower left side of the body 1. An adjustment seat 18 is installed at the upper end of the telescopic end of the electric push rod 17. The input end of the electric push rod 17 is electrically connected to the output end of the controller 2. The electric push rod 17 starts to run through the control of the controller 2. The electric push rod 17 adjusts the height of the protective box 26 through the adjustment seat 18. (During the movement of the adjustment seat 18, the mounting groove provides a guide support to reduce the radial force applied by the adjustment seat 18 to the electric push rod 17, and prevent the telescopic end of the electric push rod 17 from bending and deforming. The radial force of the electric push rod 17 is slidably borne by the mounting groove. The electric push rod 17 is only subjected to the vertical axial force.)

[0025] The adjustment seat 18 has a fixed seat 19 on its left side at the front end. A push plate 20 is slidably connected to a groove in the middle of the front end of the fixed seat 19. An electric push rod 21 is located in the middle of the rear wall of the fixed seat 19. The front end of the telescopic end of the electric push rod 21 is fixedly connected to the rear end of the push plate 20. The input end of the electric push rod 21 is electrically connected to the output end of the controller 2. The telescopic end of the electric push rod 21 extends and retracts, thereby driving the marking blade 563 to move forward via the push plate 20. During the subsequent movement (as the push plate 20 moves, the slide groove provides a guide support, reducing the radial force applied by the push plate 20 to the electric push rod 21, preventing the extension end of the electric push rod 21 from bending and deforming, the radial force of the electric push rod 21 is borne by the slide groove, and the electric push rod 21 is only subjected to the front and rear axial forces), when the distance between the rear end of the laser rangefinder 25 and the front side of the body 1 is equal to c, this indicates that the marking blade 2 563 has cut the paraffin block and made contact with the front end of the fixture.

[0026] Among them: a fixed seat 22 is set on the front side of the right end of push plate 20; push plate 23 is slidably connected in the slide groove 2 opened in the middle of the right end of fixed seat 22; a protective box 26 is set on the right end of push plate 23; a laser rangefinder 25 is set in the middle of the rear end of push plate 23, and the laser rangefinder 25 corresponds to the front and rear position of the body 1; an electric push rod 3 24 is set in the middle of the left wall of fixed seat 22; the right end of the telescopic end of electric push rod 3 24 is fixedly connected to the left end of push plate 23; the input end of electric push rod 3 24 is electrically connected to the output end of controller 2; the laser... The rangefinder 25 is bidirectionally electrically connected to the controller 2. Under the control of the controller 2, the electric push rod 24 starts to operate. The telescopic end of the electric push rod 24 extends, thereby causing the electric push rod 24 to drive the protective box 26 to move through the push plate 23. (During the movement of the push plate 23, the slide groove 2 provides a guide support to reduce the radial force applied by the push plate 23 to the electric push rod 24, and prevent the telescopic end of the electric push rod 24 from bending and deforming. The radial force of the electric push rod 24 is borne by the slide groove 2, and the electric push rod 24 is only subjected to the left and right axial forces).

[0027] Among them, a camera 28 is set in the middle of the rear end of the protective box 26. The camera 28 is bidirectionally electrically connected to the controller 2. During the movement of the protective box 26, the optical lens of the camera 28 captures images. Then, the camera 28 converts the captured image data into electrical signals through the built-in image sensor. After that, the camera 28 converts the electrical signals into digital signals through the built-in analog-to-digital converter. Finally, the camera 28 transmits the converted digital signals to the controller 2 through the built-in data transmission module.

[0028] The working principle of the paraffin slicer with a cutting mark structure provided by this utility model is as follows: Before use, select the corresponding clamp according to the paraffin type. Then, fix the clamp to the front center of the connecting seat 10 with fastening screws. Then, fix the paraffin block with the clamp (the clamp can be a mechanical clamp, which usually consists of an adjustable clamping plate and a placement platform. The clamping plate is adjusted by screws or knobs to accommodate paraffin blocks of different sizes and shapes). Then, the operator presses the corresponding control switch 27 according to the size of the paraffin block (press the upper control switch 27 for large sizes and the lower control switch 27 for small sizes). When slicing a large paraffin block, the operator presses the upper control switch 27. At this time, the circuit between the external power supply and controller 2 is closed. The input pin of controller 2 receives the electrical signal generated by the closed circuit, thereby enabling controller 2 to recognize the user's control operation and determine which control switch 27 the user has selected. Based on the user's operation, the servo motor 53 starts running through the control of controller 2. The output shaft of the servo motor 53 drives the worm gear 54 to rotate. During the rotation of the worm gear 54, it drives the worm wheel 55 to rotate through the meshing connection. During the rotation of the worm wheel 55, it drives the drive plate 52 to rotate through the mounting rod 51. At this time, the adjusting rod 564 slides inside the adjusting groove and rotates relative to the adjusting groove, thereby causing the drive plate 52 to move the fixed rod 561 through the adjusting rod 564. At this time, the right... The side fixing rod 561 drives the marking blade 562 forward, and the left fixing rod 561 drives the marking blade 563 backward. During the rotation of the mounting rod 51, the mounting rod 51 also drives the probe of the potentiometer 57 to rotate. The probe drives the sliding contact inside the potentiometer 57 to rotate. At this time, the position of the sliding contact on the resistive element changes. When the sliding contact moves on the resistive element, the resistance value between the sliding contact and the two fixed terminals changes. Then, the potentiometer 57 detects the changed resistance value through its internal detection element. Finally, the potentiometer 57 calculates the rotation angle of the drive board 52 based on the known relationship between the resistance value and the angle. Afterward, the potentiometer 57 transmits the detected information to the driver board 52 through its built-in data transmission module. Controller 2 receives the detected data via its built-in serial communication port. When the drive board 52 rotates 90°, it indicates that the second marking blade 563 extends to the designated position, while the first marking blade 562 retracts to the designated position. Then, the distance between the rear end of the second marking blade 563 and the front end of the fixture is measured (e.g., 'a'). The distance between itself and the machine body 1 is then measured using a laser rangefinder 25. During use, the built-in light source of the laser rangefinder 25 emits a laser beam to the front of the machine body 1. When the laser beam contacts the front of the machine body 1, it is reflected. The laser rangefinder 25 then receives the reflected light and measures the time-of-flight (TOF) or phase difference of the laser beam.This allows for the calculation of the distance between the rear end of laser rangefinder 25 and the front of body 1 (e.g., denoted as b). Laser rangefinder 25 then transmits the detected information to controller 2 via its built-in data transmission module. Controller 2 receives the detected data via its built-in serial communication port. Subtracting the distance between the rear end of marking blade 263 and the front end of the fixture from the distance between the rear end of laser rangefinder 25 and the front of body 1, we can obtain the distance between the rear end of laser rangefinder 25 and the front of body 1 when marking blade 263 contacts the front end of the fixture (e.g., denoted as c, c=ba). Then, through the control of controller 2, electric push rod 324 is opened... Upon initial operation, the telescopic end of the electric actuator 24 extends, causing the electric actuator 24 to move the protective box 26 via the push plate 23. (During the movement of the push plate 23, the slide groove 2 provides a guiding support, reducing the radial force applied to the electric actuator 24 by the push plate 23 and preventing the telescopic end of the electric actuator 24 from bending or deforming. The radial force of the electric actuator 24 is borne by the sliding of the slide groove 2, and the electric actuator 24 is only subjected to lateral axial forces.) During the movement of the protective box 26, the optical lens of the camera 28 captures images. The camera 28 then converts the captured image data into electrical signals using its built-in image sensor. The camera 28 then converts the electrical signals into digital signals using its built-in analog-to-digital converter. Finally, the image is captured... The camera 28 transmits the converted digital signal to the controller 2 via its built-in data transmission module. The controller 2's built-in signal transceiver module receives the image data captured by the camera 28. The controller 2 then performs image recognition. When the protective box 26 moves to the front of the paraffin block, the controller 2 recognizes the paraffin block. Based on the recognition result, it calculates the position and orientation of the upper left corner of the paraffin block. Then, it uses a geometric transformation or coordinate system transformation algorithm to convert the position of the paraffin block into the coordinate system of the protective box 26 (the camera 28 and the protective box 26 typically use different coordinate systems; the vision system is based on image pixels, while the protective box 26 is based on actual physical space. Therefore, it is necessary to convert the position information in the vision system into the coordinate information used by the protective box 26). Afterwards, controller 2, based on the converted coordinates, controls electric actuator 17 and electric actuator 3 24 to operate simultaneously. Electric actuator 17 adjusts the height of the protective box 26 via adjusting seat 18 (during the movement of adjusting seat 18, the mounting groove provides a guide support, reducing the radial force applied by adjusting seat 18 to electric actuator 17, preventing the extension end of electric actuator 17 from bending and deforming; the radial force of electric actuator 17 is borne by the sliding of the mounting groove, and electric actuator 17 is only subjected to vertical axial force). Electric actuator 3 24 adjusts the position of the protective box 26 via push plate 23 until marking blade 2 563 is aligned with the marking area in the upper left corner of the paraffin block. After adjusting marking blade 2 563, the controller 2 then controls the operation.Electric actuators 17 and 34 stop operating, while electric actuator 21 starts operating. The telescopic end of electric actuator 21 extends and retracts, causing it to move the marking blade 263 backward via push plate 10. (During this movement, slide groove 1 provides a guide support, reducing the radial force applied to electric actuator 21 by push plate 120 and preventing bending deformation of the telescopic end of electric actuator 21. The radial force of electric actuator 21 is borne by slide groove 1, and electric actuator 21 is only subjected to axial force.) When the distance between the rear end of laser rangefinder 25 and the front side of the machine body 1 is equal to c, this indicates that marking blade 263 has cut the paraffin block and is in contact with the front end of the clamp. Then the operator removes... The edges of the paraffin block are cut off. Then, under the control of controller 2, the telescopic end of electric push rod 21 extends, causing electric push rod 21 to drive marking blade 563 forward and reset via push plate 20. Marking blade 563 cuts off a portion of the upper left corner of the paraffin block, thus marking it. The mark records the slicing information of the paraffin block, which can be used to determine the slicing position, thickness, and order later. During the slicing process of the paraffin block with the marking structure, the thickness of the paraffin block slice is first set to 'd', then the distance between the paraffin block and blade 4 is measured (e.g., 'e'). Then, the distance between the paraffin block and the rear end of connecting plate 7 is measured using laser rangefinder 12 (e.g., 'f'). The working principle of 12 is the same as that of laser rangefinder 25. Then, by adding the thickness of the paraffin block slice and the distance between the front end of laser rangefinder 12 and the rear end of connecting plate 7, the distance when the paraffin block moves to blade 4 can be calculated (e.g., g, where g = d + e + f). Then, through the control of controller 2, electric push rod 11 starts to operate. The telescopic end of electric push rod 11 extends, thereby driving the sliding column 8 forward through connecting plate 7. (During the movement of connecting plate 7, guide column 6 provides a guide support, reducing the radial force applied by connecting plate 7 to electric push rod 11, preventing the telescopic end of electric push rod 11 from bending and deforming, and guiding the radial force of electric push rod 11.) The sliding column 6 bears the load, while the electric push rod 11 is only subjected to axial forces. The sliding column 8 drives the connecting seat 10 forward via the fixed plate 9, thereby causing the connecting seat 10 to move the paraffin block forward via the clamp. When the distance between the front end of the laser rangefinder 12 and the rear end of the connecting plate 7 is equal to g, it means that the paraffin block has moved to the designated position. Subsequently, the operator rotates the operating rod 16, which drives the drive rod 14 to rotate via the central wheel 13. Since the central axis of the drive rod 14 is different from that of the central wheel 13, the drive rod 14 will have lateral and vertical displacements during rotation. During the subsequent rotation of the drive rod 14, the drive rod 14 will both slide inside the drive groove and rotate relative to the drive groove. When the drive rod 14 rotates downwards...The drive rod 14 drives the connecting seat 10 downwards via the fixed plate 9. The connecting seat 10 then drives the paraffin block downwards via the clamp. During the movement of the paraffin block, the blade 4 contacts the paraffin block, thus slicing it. Since the diameter of the central wheel 13 is larger than the height of the paraffin block, the slicing of the paraffin block is completed when the drive rod 14 rotates to its lowest position. When the drive rod 14 moves upwards, it drives the connecting seat 10 upwards via the fixed plate 9. The connecting seat 10 then drives the paraffin block upwards via the clamp. When the upper end of the fixed plate 9 contacts the lower end of the pressure sensor 15, the fixed plate 9 applies pressure to the pressure sensor 15. This pressure is transmitted to the sensitive element inside the pressure sensor 15, and the change in pressure causes a change in the resistance value of the sensitive element. The change in resistance causes a change in the output voltage of the detection element. The pressure sensor 15 then measures the voltage signal and transmits the detected information to the controller 2 via its built-in data transmission module. The controller 2 receives the detected data through its built-in serial communication port. When the controller 2 receives this signal, it activates the electric push rod 11, extending its telescopic end. This extension causes the electric push rod 11 to move the sliding column 8 forward via the connecting plate 7. The sliding column 8 then moves the connecting seat 10 forward via the fixing plate 9. The connecting seat 10 then moves the paraffin block forward via the clamp. The distance the paraffin block moves is equal to d+g. The operator then continues to rotate the operating rod 16 to slice the paraffin block again.
