Description

Technical Field

[0002] Pathology is a basic medical science that studies the causes, mechanisms, development laws of human diseases, as well as the morphological structure, functional metabolism changes and pathological outcome of the body during the disease process.

[0003] The research of pathology is inseparable from the preparation and observation of pathological slides. Common pathological sections include pathological tissue sections, blood smears, liquid-based cytology, etc.; the preparation methods of different types of pathological sections are different, and the currently commonly used observation methods include real-time observation under a microscope, and scanning into digital slides for observation on a computer screen or various electronic terminal devices.

[0004] In recent years, with the rise of remote consultation and the continuous development of pathological AI artificial intelligence-assisted diagnosis, the application of digital slide technology has become more and more extensive and the demand has become greater and greater. Especially for AI artificial intelligence-assisted diagnosis, the demand for digital slide scanning devices with high efficiency, high stability and high imaging quality is becoming more and more urgent. At present, the throughput of commonly used digital slide scanning devices on the market is continuously developing from low to high, and full-automatic high-throughput digital slide scanning devices have become an urgent need for major hospitals, AI artificial intelligence-assisted diagnosis R & D companies, and third-party inspection institutions.

[0005] At present, most of the high-throughput digital slide scanning devices on the market adopt a basket type and a single-piece loading and unloading method for circular scanning. However, it is difficult for this type of device to adapt to different types of slide sources and preparation processes, and the failure rate and fragmentation rate are high, resulting in sample loss, tense doctor-patient relationships, and continuous customer complaints. This type of device with a high failure rate not only fails to meet the demand for high efficiency, but instead reduces the scanning efficiency and wastes labor costs.

Detailed implementation mode

[0026] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0027] As Figure 1 , Figure 2 and Figure 4 shown, the embodiment of the present application provides a carrier plate type full-automatic digital slice scanning system, including a base 1 and a bracket 2 vertically fixed on the base 1 along the Y-axis direction. A microscopic optical imaging system 6 and a storage bin lifting assembly 7 are arranged in parallel between the bracket 2 and the bottom plate along the Y-axis direction. The storage bin lifting assembly 7 is arranged in two in parallel. A portable carrier plate storage bin 8 is provided at the output end of each storage bin lifting assembly 7. A plurality of chip storage carrier plates 9 can be pulled and pushed in each portable carrier plate storage bin 8. It further includes a scanning motion device 3 that can perform scanning motion below the microscopic optical imaging system 6. The scanning motion device 3 includes an X-axis linear motor 31 arranged on the bottom plate facing the portable carrier plate storage bin 8, a Y-axis linear motor 32 arranged at the output end of the X-axis linear motor 31, a Z-axis automatic positioning platform 33 arranged at the output end of the Y-axis linear motor 32, and a carrier stage 34 arranged on the Z-axis automatic positioning platform 33. An loading and unloading pulling and pushing assembly 4 is arranged on the carrier stage 34, which can pull the chip storage carrier plate 9 in the portable carrier plate storage bin 8 to the carrier stage 34 or push the chip storage carrier plate 9 on the carrier stage 34 back into the portable carrier plate storage bin 8.

[0028] The present invention provides two portable plate storage bins 8, and provides a plurality of storage plates 9 in each portable plate storage bin 8. The plurality of storage plates 9 can be used to place different types of slides, and can adapt to the basic tolerances of slides produced by different manufacturers. The present invention has a relatively wide range of applications. When working, the storage bin lifting assembly 7 can drive the portable plate storage bin 8 to rise and fall so that the plurality of storage plates 9 can be aligned with the loading and unloading pull-push assembly 4 layer by layer. The loading and unloading pull-push assembly 4 pulls the storage plates 9 layer by layer to the carrier 34, and the scanning motion device 3 drives the storage plates 9 The sample on the surface performs a surface scanning motion under the microscope optical imaging system 6, and during the surface scanning motion, the Z-axis automatic positioning platform 33 will also automatically perform micro-movement in the Z-axis direction to realize the dynamic focusing of the microscope optical imaging system 6 on the slide on the film storage carrier 9 to realize the slice scanning of the sample. Finally, the loading and unloading material pulling and pushing component 4 will push the tested film storage carrier 9 layer by layer into the portable carrier storage bin 8. When the slice scanning of one of the portable carrier storage bins 8 is completed, the slice scanning of the other portable carrier storage bin 8 can continue without stopping and waiting.

[0029] The above method can achieve unlimited cyclic loading. Compared with the traditional single-piece loading and unloading method, it is not easy to cause damage to the slide. It also has the advantages of high scanning efficiency and low failure rate, and can better meet the needs of mainstream customers in the current market.

[0030] On the basis of the above, if Figure 3 As shown, the storage bin lifting assembly 7 includes a first linear motor 71 and a support plate 72, a support plate 73 is fixed on the base 1, one end of the first linear motor 71 is fixedly connected to the bracket 2, and the other end is fixedly connected to the support plate 73, the support plate 72 is fixedly connected to the output end of the first linear motor 71 parallel to the base 1, and the portable carrier storage bin 8 is placed on the support plate 72.

[0031] Specifically, the two support plates 72 are arranged back to back and do not interfere with each other when working. When working, the scanning motion device 3 first drives the carrier 34 to move along the Y-axis direction to the side facing the portable carrier storage bin 8, and then moves along the X-axis direction to make it close to the portable carrier storage bin 8. The first linear motor 71 drives the portable carrier storage bin 8 to rise and fall, so that each layer of storage carrier 9 can be maintained at the same horizontal height with the carrier 34, which can facilitate the loading and unloading pulling and pushing components 4 to perform loading and unloading actions.

[0032] The above method makes the loading and unloading of the storage plate 9 more stable and reliable, and can reduce the fragmentation rate of the glass slides during the loading and unloading process.

[0033] On the basis described above, at least two ball head locating pins 721 are provided on the end face of the pallet 72, and positioning holes 82 adapted to the ball head locating pins 721 are provided on the portable carrier storage bin 8. The positioning holes 82 and the ball head locating pins 721 correspond to each other in number and position one by one, and the ball head locating pins 721 can be inserted into the positioning holes 82.

[0034] When the portable carrier storage bin 8 is placed on the pallet 72, the two ball head locating pins 721 can be respectively and limit-inserted into the positioning holes 82.

[0035] In the above manner, through the arrangement of the ball head locating pins 721 and the positioning holes 82, on the one hand, it is convenient to accurately position the portable carrier storage bin 8, and on the other hand, the portable carrier storage bin 8 has good stability and is not easy to slip.

[0036] On the basis described above, as Figure 4 shown, slots 81 are respectively provided on the two inner side walls of the portable carrier storage bin 8 on the same plane, and the two slots 81 form a board carrier storage slot. The board carrier storage slot is longitudinally provided with several, and the chip storage carrier 9 can be pull-push connected in the board carrier storage slot.

[0037] Specifically, the distance between every two board carrier storage slots can be set to different sizes according to the thickness and size of the sample to be measured in actual use.

[0038] In the above manner, through the arrangement of the storage slot, the pull-push of the chip storage carrier 9 is made more convenient and fast.

[0039] On the basis described above, the Z-axis automatic positioning platform 33 is a wedge-shaped Z-axis platform. The wedge-shaped Z-axis platform includes a Z-axis seat, a lifting wedge block longitudinally slidably connected in the Z-axis seat, and a driving wedge block horizontally slidably connected in the Z-axis seat. The opposite surfaces of the lifting wedge block and the driving wedge block are respectively provided with mutually adapted wedge surfaces, and a power element for controlling the horizontal movement of the driving wedge block to cause the longitudinal lifting of the lifting wedge block is provided on the Z-axis seat.

[0040] It should be noted that the above manner is the preferred implementation manner in this embodiment. The Z-axis automatic positioning platform 33 can also be a pneumatic Z-axis platform in the prior art.

[0041] During operation, the power element controls the driving wedge block to perform horizontal movement. Under the action of the wedge surface, the lifting wedge block performs longitudinal lifting to drive the carrier table 34 to lift.

[0042] In the above manner, by adopting a wedge-shaped structure, it is beneficial to improve the movement stability of the Z-axis automatic positioning platform 33.

[0043] On the basis described above, the wedge surface transmission ratio of the driving wedge block and the lifting wedge block is 1:4.

[0044] Specifically, during operation, when the horizontal movement stroke ratio of the driving wedge block is 1, the longitudinal lifting stroke ratio of the lifting wedge block is 4.

[0045] In the above manner, the wedge surface transmission ratio of the driving wedge block and the lifting wedge block is set to 1:4. Compared with the traditional Z-axis positioning platform, its motion resolution is increased by 4 times, which is beneficial to improving its motion accuracy.

[0046] On the above basis, as Figure 5 shown, the loading and unloading pulling and pushing assembly 4 includes a support 41 fixed on the carrier 34, a pulling and pushing linear motor 42 fixed on the support 41, and a linear guide rail slider 44 slidably connected to the support 41. The center lines of the pulling and pushing linear motor 42 and the linear guide rail slider 44 are parallel to each other. A T-shaped pull head 43 is fixedly connected to the telescopic rod of the pulling and pushing linear motor 42. One end of the linear guide rail slider 44 away from the support 41 is fixedly connected to one side of the T-shaped pull head 43. A T-shaped bayonet 91 adapted to the T-shaped pull head 43 is provided on the storage plate 9. The support 41 is further provided with a telescopic limit assembly for limiting the telescopic stroke of the linear guide rail slider 44.

[0047] It should be noted that the pulling and pushing linear motor 42 is a telescopic linear motor.

[0048] During operation, under the guiding action of the linear guide rail slider 44, the telescopic rod of the pulling and pushing linear motor 42 drives the T-shaped pull head 43 to extend. The storage bin lifting assembly 7 drives the portable carrier storage bin 8 to rise, so that the T-shaped bayonet 91 is stuck on the T-shaped pull head 43. The piston rod of the pulling and pushing linear motor 42 contracts, thereby pulling the storage plate 9 onto the carrier 34. When it is necessary to push the storage plate 9 back into the portable carrier storage bin 8, the above steps can be repeated in reverse.

[0049] The above manner has the advantages of simple structure and good pulling and pushing stability.

[0050] On the above basis, the telescopic limit assembly includes an induction piece 45 arranged on the support 41 around the outer periphery of the linear guide rail slider 44, a push-out limit sensor 46 and a retraction limit sensor 47 respectively arranged on the support 41 on one side of the linear guide rail slider 44.

[0051] Specifically, the induction sheet 45 can be an infrared ranging sensor, an ultrasonic ranging sensor, a contact ranging sensor, etc. During operation, it is used to detect the expansion and contraction of the guide rail slider, so as to detect the sliding stroke of the T-shaped pull head 43. The push limit inductor 46 and the retraction limit inductor 47 are both proximity sensors. A push limit trigger point and a retraction limit trigger point are respectively set at the corresponding limit positions of the guide rail slider. When the corresponding limit position is reached, the push-pull linear motor 42 stops working.

[0052] The above method can ensure the position stability of the film storage carrier 9 when it is pulled out and pushed back.

[0053] On the above basis, as Figure 6 shown, the microscopic optical imaging system 6 includes an imaging lens barrel assembly 61 and a light source lens assembly 62. The imaging lens barrel assembly 61 is fixed on the bracket 2 above the stage 34, and the light source lens assembly 62 is fixed on the base 1 below the stage 34. The imaging lens barrel assembly 61 and the light source lens assembly 62 are coaxially arranged. There is a gap for the movement of the stage 34 between the imaging lens barrel assembly 61 and the light source lens assembly 62. A square groove for the light of the light source lens assembly 62 to pass through is provided on the stage 34.

[0054] Specifically, the film storage carrier 9 is made of a transparent material. During operation, the glass slide calibrated with the sample is placed on the film storage carrier 9. The light source lens assembly 62 provides a background light source, and the imaging lens barrel assembly 61 scans and identifies it to convert it into a digital signal.

[0055] In the above method, the light source lens assembly 62 and the imaging lens barrel assembly 61 are modularly arranged, and the imaging lens barrel assembly 61 and the light source lens assembly 62 are coaxially arranged, which is beneficial to improving the scanning and recognition accuracy of the sample.

[0056] On the above basis, as Figure 2 shown, an X-axis auxiliary guide rail 35 is arranged on the bottom plate parallel to the X-axis linear motor 31. An X-axis auxiliary slider is slidably connected to the X-axis auxiliary guide rail 35. One end of the bottom of the Y-axis linear motor 32 is fixedly connected to the output end of the X-axis linear motor 31, and the other end of the bottom is fixedly connected to the X-axis auxiliary slider.

[0057] Through the setting of the X-axis auxiliary guide rail 35, the Y-axis linear motor 32 slides more stably and smoothly along the X-axis.

[0058] The above are only the preferred embodiments of the present invention, and the protection scope of the present invention is not limited to the above embodiments. All technical solutions falling within the concept of the present invention belong to the protection scope of the present invention. It should be noted that for those of ordinary skill in the art, several improvements and refinements made without departing from the principle of the present invention should also be regarded as within the protection scope of the present invention.
