Description

Technical Field

[0001] This utility model relates to the field of medical device technology, and in particular to a pathological diagnostic microscope. Background Technology

[0002] The pathological diagnostic microscope is a core piece of equipment for clinical medical pathological testing. It is mainly used for magnified observation of pathological tissue sections and lesion analysis. It is a key instrument for disease diagnosis and pathological analysis and is widely used in hospital pathology departments, medical testing laboratories and research institutions. Its stability and ease of operation directly affect the accuracy of pathological diagnosis results and the efficiency of testing.

[0003] Currently, most commercially available pathological diagnostic microscopes feature a fixed stage with a flexible slide clamping design. Over long-term practical use, this design has revealed numerous technical shortcomings, making it difficult to meet the demands of high-frequency, high-standard pathological examinations. The flexible slides are often in a compressed clamping state, constantly in close contact with the stage to store energy. After prolonged periods of inactivity, they are prone to elastic fatigue and pressure attenuation, or deformation from repeated lifting. This results in an inability to stably clamp the pathological slides during subsequent use, causing specimens to wobble and shift, directly interfering with the field of view and leading to inaccurate diagnostic results. Furthermore, the stages of conventional microscopes are often fixed and non-retractable. Specimen changes require operators to manually reach into the narrow space at the bottom of the eyepiece, which is not only cumbersome and inconvenient, but also time-consuming for batch specimen testing. It also increases the risk of accidentally touching the lens or disturbing the microscope's position, further affecting accuracy. Utility Model Content

[0004] The technical problem to be solved by this invention is that the existing technology has the disadvantages of some components being easily damaged and the operation being cumbersome. To address this, we propose a pathological diagnostic microscope.

[0005] To achieve the above objectives, this application adopts the following technical solution: a pathological diagnostic microscope, including a support stage, an eyepiece assembly mounted on the top of the support stage, mounting plates fixedly connected to both sides of the support stage, a sliding groove formed on the surface of the mounting plate, an L-shaped sliding plate slidably connected to the inner wall of the sliding groove, a support plate fixedly connected to the top of the two L-shaped sliding plates, pressure plates mounted on both sides of the top of the support plate, two support sliding rods slidably connected to the inner wall of the sliding groove, a connecting plate fixedly connected to one side of the two support sliding rods, and a carrying plate fixedly connected to the top of the four support sliding rods.

[0006] Preferably, a magnetic block is fixedly connected to one side of the connecting plate, and a metal block is fixedly connected to one side of the mounting plate.

[0007] Preferably, lifting knobs are installed on both sides of the top of the support platform, and adjustment plates are installed on both sides of the eyepiece assembly. The adjustment plates are slidably connected to the holes around the eyepiece assembly through protrusions.

[0008] Preferably, a plurality of protruding plates are fixedly connected to the front end of the top of the carrier plate, and a long groove is formed on the surface of the carrier plate.

[0009] Preferably, the tablet is designed to be inclined, and the front end of the tablet is curved upwards.

[0010] Preferably, the front corner of the chute is inclined at 45 degrees, and the support slide rod at the rear section of the loading plate is deflected with the bottom of the support slide rod as the center.

[0011] The technical effects and advantages of this utility model are as follows:

[0012] In this invention, the synchronous sliding cooperation of the L-shaped sliding plate, the supporting sliding rod, and the sliding groove, combined with the magnetic locking structure of the magnetic block and the metal block, enables the synchronous pulling and moving of the carrier plate and the supporting plate. The carrier plate can be quickly moved out of the working area of ​​the eyepiece assembly. With the anti-drop design of the protruding plate at the front end of the carrier plate, it is not necessary to manually reach into the narrow space at the bottom of the eyepiece assembly when changing specimens, avoiding accidental contact with the lens or disturbance to the equipment. Moreover, the magnetic locking does not require additional pressing of the unlocking parts, and pulling and resetting can be completed in one step, greatly simplifying the specimen changing steps and shortening the testing time of a single sample. It is especially suitable for batch specimen testing scenarios in pathology laboratories, effectively improving the overall testing efficiency.

[0013] In this invention, designed for use in high-cleanliness and high-disinfection scenarios such as hospitals and pathology laboratories, the high-frequency hand-contact components such as the adjustment knob and lifting knob are designed as detachable magnetic structures. They can be disassembled individually for high-temperature sterilization and deep disinfection, avoiding cross-contamination between different test samples and meeting the hygiene and safety standards of medical testing equipment. At the same time, the deflection and pulling trajectory of the carrier plate is smooth, without jamming or violent shaking, and the operating force is uniform, without disturbing the overall placement of the support platform, further ensuring the safety and standardization of the testing operation.

[0019] The present invention will now be described in further detail with reference to the accompanying drawings and preferred embodiments. These drawings are simplified schematic diagrams, which only illustrate the basic structure of the present invention in a schematic manner, and therefore only show the components related to the present invention.

[0020] Reference Figures 1-4 As shown, this utility model provides a technical solution: a pathological diagnostic microscope, including a support stage 1, an eyepiece assembly 2 installed on the top of the support stage 1, mounting plates 3 fixedly connected to both sides of the support stage 1, a sliding groove 4 opened on the surface of the mounting plate 3, an L-shaped sliding plate 5 slidably connected to the inner wall of the sliding groove 4, a support plate 6 fixedly connected to the top of the two L-shaped sliding plates 5, pressure plates 7 installed on both sides of the top of the support plate 6, two support sliding rods 8 slidably connected to the inner wall of the sliding groove 4, a connecting plate 9 fixedly connected to one side of the two support sliding rods 8, and a carrying plate 10 fixedly connected to the top of the four support sliding rods 8. When the user pulls the carrying plate 10 forward, it drives the multiple support sliding rods 8 on both sides to slide forward along the inner wall of the sliding groove 4. At the same time, the connecting plate 9 follows the support sliding rods 8 forward, pulling the L-shaped sliding plate 5 and the support plate 6 to move. The L-shaped sliding plate 5 follows the support sliding rods 8 to slide linearly along the inner wall of the sliding groove 4, so as to realize the synchronous forward movement of the support plate 6 and the carrying plate 10.

[0021] As the bottom of the L-shaped slide plate 5 slides along the straight groove of the slide 4, the specimen plate 10 and the support plate 6 gradually move away from the working area of ​​the eyepiece assembly 2 and then move to the front end of the bottom of the eyepiece assembly 2, so that the support plate 6, the pressing plate 7, and the specimen plate 10 are completely removed from the obstruction area of ​​the eyepiece assembly 2. During this process, when the support slide rod 8 slides along the inner wall of the slide 4 to the front downward tilting area, the front support slide rod 8 is guided to gradually move down along the tilting part of the slide 4, while the rear support slide rod 8 is always in the straight groove of the slide 4. This makes the two support slide rods 8 on both sides in the front position tilted, so that the specimen plate 10 deflects downward with the rear support slide rod 8 as the center, while the position of the rear support plate 6 remains unchanged. As the specimen plate 10 deflects, the contact point between the front end of the pressing plate 7 and the surface of the specimen plate 10 no longer contacts it after the specimen plate 10 moves downward, which causes the front end of the pressing plate 7 to rebound downward. This is because the pressing plate 7 originally has elasticity and is always in contact with the surface of the specimen plate 10 to achieve the clamping of the specimen.

[0022] This makes the carrier plate 10 and the support plate 6 present a Figure 3In the intermediate state, the pressure plate 7 is in a state of no force and springs down on its own. This is the state of the device when it is not in use. At this time, the pressure plate 7 is in a free state to avoid long-term contact with the carrier plate 10, which would reduce the downward pressure. This solves the problem of elastic fatigue caused by the pressure plate 7 being in a state of compression and energy storage for a long time. It also avoids the situation where the clamping force is insufficient when the device is used again after a long period of inactivity, which would cause the specimen to shake and shift during the test, affecting the accuracy of the final test results.

[0023] When the device needs to be used again to place a specimen for examination, simply place the specimen in the middle of the tilted carrier plate 10, and then push the carrier plate 10 backward to reset it to its initial state. This allows the specimen on the surface of the carrier plate 10 to contact the bottom of the pressure plate 7. The downward elastic force of the pressure plate 7 clamps and fixes the specimen between the pressure plate 7 and the carrier plate 10. Then, push the carrier plate 10 back to the working area of ​​the eyepiece assembly 2. During the reset process, the carrier plate 10 will gradually rise so that the top of the specimen presses against the front end of the pressure plate 7, causing the pressure plate 7 to be squeezed and lifted again, forming a stable clamp and fixation for the specimen placed on the surface of the carrier plate 10. Subsequent testing can then begin. The entire removal and reset process is simple to operate and does not require separate adjustment of the clamping structure, reducing the operational threshold. It also effectively extends the service life of the elastic clamping components and improves the stability of the device's test results.

[0024] Reference Figure 3 and Figure 4 As shown in this embodiment: a magnetic block 11 is fixedly connected to one side of the connecting plate 9, and a metal block 12 is fixedly connected to one side of the mounting plate 3. Since the metal block 12 is made of metal, when the device is in the initial state, the rear side of the magnetic block 11 tightly attracts the metal block 12, fixing the positions of the connecting plate 9 and the support slide rod 8. At this time, the carrying plate 10 is in the working position. When it is necessary to move the carrying plate 10, it is only necessary to pull the carrying plate 10 outward. The pulling force is greater than the magnetic attraction between the magnetic block 11 and the metal block 12, which can move the connecting plate 9 and the carrying plate. The entire plate 10 moves outward, and can be unlocked and pulled without the need for additional pressing of the locking structure, simplifying the operation steps. When the plate 10 is pushed back to its initial working position, the magnetic block 11 will be attracted and fixed by magnetic force after approaching the metal block 12, automatically completing the position locking. It will not cause the plate 10 to shift due to accidental contact during the detection process, thus avoiding any impact on the detection accuracy. The magnetic attraction locking method does not have a complicated buckle structure, and there will be no problem of component wear and jamming even after repeated opening and closing for a long time. It is more durable and easier to maintain.

[0025] Reference Figure 4As shown in this embodiment: Lifting knobs 13 are installed on both sides of the top of the support platform 1, and adjusting plates 14 are installed on both sides of the eyepiece assembly 2. The adjusting plates 14 are slidably connected to the holes around the eyepiece assembly 2 via protrusions. The lifting knobs 13 and adjusting plates 14 serve as the eyepiece magnification and height adjustment knobs, respectively. The installation method adopts a detachable design. The adjusting plates 14 are divided into two, with the relatively close side magnetically fixed, and multiple vertical blocks are set inside to insert and limit their position on the surface of the eyepiece assembly 2. The lifting knobs 13 are inserted on both sides of the top of the support platform 1, and their inner walls are semi-circular, facilitating the disassembly, cleaning, or replacement of frequently touched parts of the device by staff. Furthermore, in usage scenarios with high cleaning and disinfection requirements, such as hospitals and epidemic prevention laboratories, the detachable structure allows for individual high-temperature sterilization or deep disinfection of frequently touched parts such as knobs, avoiding cross-contamination.

[0026] Reference Figure 3 As shown in this embodiment: several protruding plates 15 are fixedly connected to the front end of the top of the carrier plate 10. The surface of the carrier plate 10 is provided with a long groove. The setting of the protruding plates 15 directly prevents the test specimen from falling when the carrier plate 10 is in an inclined state. The long groove makes it easier for the user to pull the carrier plate 10 to move. The protruding plates 15 prevent the specimen from falling. When the pressure plate 7 clamps the specimen, the specimen will automatically slide to the protruding plate 15 when the carrier plate 10 moves forward to release the clamping of the pressure plate 7. Then the staff can easily take out the specimen for replacement.

[0027] Reference Figure 3 As shown in this implementation scheme: the slide 7 is designed with an incline, and the front end of the slide 7 is curved upwards. This special design allows the specimen to naturally fit the clamping surface when placed, preventing the specimen from slipping due to an overly straight clamping angle. The curved upwards front end can also play a preliminary guiding and positioning role for specimens of different thicknesses. Whether it is a regular-sized glass slide or a slightly thicker tissue section, it can smoothly slide into the gap between the slide 7 and the carrier plate 10 along the curved slope. The initial placement can be completed without the need for manual adjustment by the staff. In scenarios where batch testing of samples is required, it can effectively reduce the operation time of a single sample and improve the overall testing efficiency.

[0028] Reference Figure 3 As shown in this implementation scheme: the front corner of the slide 4 is tilted at 45 degrees, and the bottom of the support slide rod 8 at the rear end of the loading plate 10 is deflected with the center of the circle. Through the 45-degree tilted corner design, the loading plate 10 can naturally form a slight tilt angle during the process of pulling out to replace the specimen. Combined with the deflection trajectory with the center of the circle at the bottom, the pulling process will not be stuck. This deflection trajectory allows the staff to pull out the loading plate 10 with more uniform force, and will not cause the entire device to shake due to excessive force, thus ensuring the stability of the device for placing the test sample.
