Description

Technical Field

[0001] This utility model relates to the field of medical optical instrument technology, specifically a protective pathology slide reading microscope. Background Technology

[0002] As a precision optical instrument, the microscope plays a vital role in many fields such as biology, medicine, and materials science. Especially in pathological slide reading, it is a key tool for doctors to diagnose diseases. Its core principle is based on optical imaging. Through the magnification effect of the combination of objective lens and eyepiece, tiny sample details are presented to the observer. The light emitted by the light source penetrates the sample (transmission light microscope) or is reflected from the sample surface (reflection light microscope). After being focused and adjusted by the condenser lens, it is initially magnified by the objective lens to form a real image. This real image is further magnified by the eyepiece and finally enters the human eye or is recorded by the imaging device. The objective lens converter is used to switch between objective lenses with different magnifications to meet the observation needs of different levels of sample detail. The stage is used to fix the sample. By adjusting the focal length, the image of the sample can be clearly presented.

[0003] However, over long-term use, traditional microscopes have gradually revealed some problems affecting their performance and user experience. In terms of objective lens protection, there are obvious shortcomings. For example, the objectives of conventional microscopes are usually directly exposed to the external environment and lack effective protective structures. During daily use, dust, tiny particles, and various impurities in the air can easily adhere to the surface of the objective lens. These contaminants not only affect the transmission and refraction of light, leading to a decrease in image clarity and interfering with the observation and analysis of samples by pathologists, but may also corrode the optical lenses of the objective lens. Long-term accumulation will shorten the lifespan of the objective lens and increase the cost of equipment maintenance and replacement. Utility Model Content

When rotating the objective lens converter, the synchronization rod and push block on the objective lens converter cooperate with the adjustment component to automatically complete the opening and closing of the observation port without additional operation. The whole process is smooth and efficient, saving operation time and improving the work efficiency of pathology slide reading. Attached Figure Description

[0026] 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.

[0027] Example 1, please refer to Figure 1-6 A protective pathology slide viewing microscope includes a microscope body 1, a stage 11 and an objective lens turret 12. The stage 11 is used to hold pathology slides. Multiple objective lens bodies 13 for observing pathology slides are threaded onto the objective lens turret 12. The objective lens turret 12 also has a protective assembly for protecting the multiple objective lens bodies 13. The protective assembly includes a sleeve assembly 2 on the objective lens turret 12, and an adjustment assembly 3 and a shielding assembly 4 disposed within the sleeve assembly 2. Both 13 and adjustment component 3 are located inside the sleeve assembly 2. The sleeve assembly 2 includes a sleeve body 21 and a connecting ring 22. An observation port is provided at the bottom of the sleeve body 21. The shielding component 4 is located in the adjustment component 3 and shields the observation port. The sleeve body 21 is fixedly connected to the objective lens converter 12. The top of the sleeve body 21 is threadedly connected to the connecting ring 22 by bolts. A transparent window 23 is also provided on the side wall of the sleeve body 21 to facilitate observation by the film reader. Both the adjustment component 3 and the shielding component 4 are located at the bottom of the inner wall of the sleeve body 21.

[0028] Specifically, when using this device for slide reading, first place the pathological slide to be observed on the stage 11, rotate the objective lens converter 12 through the gap between the sleeve body 21 and the connecting ring 22, and adjust the objective lens body 13 so that the appropriate objective lens body 13 is moved directly above the pathological slide. During the movement, the objective lens converter 12 simultaneously drives the adjustment component 3 inside the sleeve body 21, so that the adjustment component 3 drives the shielding component 4 to open, opening the observation port. The objective lens body 13 can be adjusted by extending through the observation port.

[0029] After the objective lens turret 12 is rotated into position, the height of the stage 11 is adjusted by rotating the coarse adjustment knob. Once adjusted to the appropriate position, the fine adjustment knob is rotated to finely adjust the objective lens body 13, and the observation of pathological slides can then be performed.

[0030] The transparent window 23 allows viewers to easily observe the magnification of the objective lens 13 and whether the objective lens 13 has been rotated to the correct position.

[0031] Example 2, please refer to Figure 1-7The adjusting component 3 includes a fixed frame 31, the bottom of which is fixed to the bottom of the inner wall of the sleeve body 21. Multiple evenly distributed limiting grooves 32 are provided on the top of the fixed frame 31. An adjusting frame 33 is rotatably connected between the fixed frame 31 and the bottom of the inner wall of the sleeve body 21. A blocking component 4 is located between the fixed frame 31 and the adjusting frame 33. An adjusting groove 34 is provided on the adjusting frame 33. A push rod 35 and a toothed assembly 36 are fixedly connected to the side wall of the adjusting frame 33, and the push rod 35 and the toothed assembly 36 are symmetrically arranged. Two sets of teeth 35 and toothed assemblies 36 are provided on the side wall of the fixed frame 31. The moving groove 37 is adapted to the position of the tooth assembly 36. A reset block 39 is slidably connected in the push rod 35, and a pressure spring is fixedly connected between the reset block 39 and the push rod 35. Multiple sets of synchronizing rods 14 are fixedly connected to the objective lens converter 12, and each set of synchronizing rods 14 is located between two adjacent objective lens bodies 13. The bottom of each set of synchronizing rods 14 is fixedly connected to a push block 15 for pushing the push rod 35 to drive the adjustment frame 33 to rotate. The bottom of the adjustment frame 33 is also fixedly connected to two sets of limiting sliders 38. The bottom of the inner wall of the sleeve body 21 is provided with two sets of limiting sliders. The sleeve body 21 also has a sliding arc groove for block 38, and a limiting block 24 for blocking the movement of the adjusting frame 33 is fixedly connected in the sleeve body 21. The top of the limiting block 24 has an inclined groove that matches the push rod 35 on the adjusting frame 33. A fixing block 26 is also fixedly connected in the sleeve body 21. A return spring 27 for assisting the adjusting frame 33 to reset is fixedly connected to the side of the fixing block 26 near the push rod 35. The other end of the return spring 27 is fixed to the push rod 35. A transmission gear 25 is also provided in the sleeve body 21, and the transmission gear 25 meshes with the tooth set 36 on the adjusting frame 33. The bottom of the drive gear 25 is provided with a connecting seat, and the bottom of the connecting seat is fixed to the bottom of the inner wall of the sleeve body 21. A spring is provided in the connecting seat. The output shaft of the drive gear 25 passes through the connecting seat and is fixed to one end of the spring. The blocking assembly 4 includes multiple sets of blocking plates 41. The top of each set of blocking plates 41 is fixedly connected with a first sliding block 42, and each first sliding block 42 slides on an adjacent limiting groove 32. The bottom of each set of blocking plates 41 is also fixedly connected with a second sliding block 43, and each second sliding block 43 slides in an adjusting groove 34.

[0032] Specifically, when the rotating objective lens turret 12 rotates the appropriate objective lens body 13 to align with the pathological slide on the stage 11, the synchronizing rod 14 on the objective lens turret 12 rotates simultaneously. Initially, the push block 15 contacts the vertical surface of the push rod 35 on the adjusting frame 33. When the objective lens turret 12 drives the synchronizing rod 14 and the push block 15 to rotate, the push block 15 pushes the reset block 39 to move, so that the reset block 39 drives the adjusting frame 33 to rotate through the push rod 35. When the adjusting frame 33 rotates, the toothed assembly 36 on the adjusting frame 33 simultaneously drives the transmission gear 25 to rotate. The transmission gear 25 drives the spring to tighten and store force, while the reset spring 27 is stretched.

[0033] When the adjusting frame 33 rotates, the multiple sets of baffles 41 on the adjusting frame 33 move under the limit of the adjusting groove 34. At the same time, the first sliding block 42 at the top of the baffle 41 slides in the limiting groove 32 on the fixed frame 31, causing the multiple sets of baffles 41 to separate and the observation port at the bottom of the sleeve body 21 to open. At this time, the push rod 35 and the reset block 39 move under the drive of the push block 15 to contact the limiting block 24 inside the sleeve body 21.

[0034] Once the objective lens turret 12 is rotated to its position, the objective lens turret 12 is fixed, and the multiple sets of shields 41 are in the separated state, so that the observation port is always in the open state. At this time, by rotating the coarse adjustment knob and the fine adjustment knob, the stage 11 or the objective lens body 13 can be adjusted up and down to observe the pathological slide.

[0035] After use, remove the pathological slide from the stage 11 and rotate the objective lens turret 12 again to rotate the objective lens body 13 so that it is misaligned with the light aperture on the stage 11. During the rotation, the adjacent push block 15 pushes the push rod 35 to continue rotating. At this time, the reset block 39 is blocked by the limit block 24 and retracts into the push rod 35, allowing the push block 15 to pass over the reset block 39 and continue rotating. After the push block 15 passes over, the reset block 39 pops out of the push rod 35 under the action of the pressure spring. At this time, the push rod 35 reverses and resets under the drive of the reset spring 27 and the spring at the bottom of the transmission gear 25. After the objective lens body 13 is rotated into place, the synchronizing rod 14 and the push block 15 between the two sets of objective lens bodies 13 on both sides of the stage 11 come into contact with the reset block 39 after reset, preparing for the next adjustment.

[0036] Working principle: When using this device to read slides, first place the pathological slide to be observed on the stage 11, and rotate the endoscope converter 12 through the gap between the sleeve body 21 and the connecting ring 22, so that the endoscope body 13 is moved to directly above the slide.

[0037] During rotation, the objective lens converter 12 synchronously drives the adjustment assembly 3 inside the sleeve body 21 to operate: the synchronous rod 14 on the converter drives the push block 15 to rotate, the push block 15 pushes the reset block 39, and drives the adjustment frame 33 to rotate through the push rod 35. The toothed assembly 36 on the adjustment frame 33 drives the transmission gear 25 to rotate, causing the spring spring to tighten and store force. At the same time, the reset spring 27 is stretched. Meanwhile, the adjustment frame 33 drives multiple sets of shielding plates 41 to move under the limit of the adjustment groove 34. The first sliding block 42 at the top of the shielding plate 41 slides along the limit groove 32 on the fixed frame 31. The multiple sets of shielding plates 41 separate, and the observation port at the bottom of the sleeve body 21 is fully opened. At this time, the push rod 35 and the reset block 39 move to contact the limit block 24 inside the sleeve body 21.

[0038] After the objective lens turret 12 is rotated into place and fixed, the observation port remains open. Rotate the coarse adjustment knob to adjust the height of the stage 11, and then rotate the fine adjustment knob to finely focus the objective lens body 13, so that slide observation can be carried out.

[0039] After use, remove the slide and rotate the objective lens turret 12 again to misalign the objective lens body 13 with the light aperture of the stage 11. The adjacent push block 15 pushes the push rod 35 to continue rotating. The reset block 39 is blocked and retracted by the limiting block 24. After the push block 15 passes, the reset block 39 pops out under the action of the pressure spring. The push rod 35 is reversed and reset under the action of the reset spring 27 and the spring spring, so that the shielding plate 41 closes and seals the observation port again.

[0040] Meanwhile, by using bolts to connect the sleeve body 21 to the connecting ring 22, the sleeve body 21 can be separated from the connecting ring 22 by removing the bolts during use, which facilitates the replacement of the objective lens.
