Description

Technical Field

[0001] The present invention relates to the technical field of pathological slice scanning devices and proposes an automatic scanning device for medical pathological slices. Background Art

[0002] Pathological examination is a morphological method for examining pathological changes in the body's organs, tissues or cells. It requires cutting a certain size of diseased tissue, making pathological sections through histological methods, and using a digital slicing system to quickly scan the entire slide. The pathological diagnosis is solved through a network communication control system.

[0003] Existing pathology slice scanners usually require doctors to place slides and cover slips on a slide tray, and then the numerical control device moves the scanner's objective lens downward to a suitable position to focus the objective lens. However, during the focusing process, if the objective lens is attached with impurities or is damaged, the objective lens will not be able to refract light correctly, resulting in a focus failure of the objective lens. After the focus failure, a clear magnified image cannot be formed in the scanner, and the numerical control device cannot receive a stop signal and continues to move the objective lens downward, causing the objective lens to contact the cover glass, squeezing the cover glass and then squeezing the slide, causing the slide and cover glass to break at the same time. The broken glass slide (hereinafter referred to as glass slide refers to slide and cover glass) will also scratch the objective lens, affecting the normal use of the objective lens.

Considering that the objective lens may be attached with some impurities or the objective lens may be damaged, resulting in a focus failure. After the focus failure, a clear magnified image cannot be formed in the scanner.

A second elastic member 251 is provided between the push plate 25 and the adjacent fixed pipe 24. The second elastic member 251 is a tension spring. The second elastic member 251 is used to maintain the initial position of the adjacent push plate 25 and drive the push plate 25 to return to the initial position after the movement. The two second elastic members 251 cooperate with each other to increase the volume of the hydraulic oil delivered to the two fixed pipes 24. The area is maintained consistent, a moving rod 26 is fixedly connected to the upper side of the push plate 25, and the moving rod 26 is sealed and slidably connected to the adjacent fixed tube 24.

The second connecting block 23 is provided with an arc groove that is slidably connected to the adjacent fixed block 27 and the adjacent moving rod 26, and the arc groove on the second connecting block 23 is concentric with the fixed plate 6. The push plate 25 drives the adjacent first moving block 8 to move synchronously through the transmission of the adjacent moving rod 26, and then drives the adjacent glass slides to move synchronously, so as to prevent the adjacent glass slides from being squeezed and broken by the objective lens.

[0034] Please combine Figure 2 , Figure 5 and Figure 6Reading this paragraph, the connecting structure includes a liquid storage ring 31, the interior of the liquid storage ring 31 is filled with hydraulic oil, the liquid storage ring 31 is embedded in the left side of the connecting tube 3, and the lower side of the liquid storage ring 31 is slidably connected with a moving ring 32, and the lower side of the moving ring 32 is fixedly connected with a second moving plate 33, the second moving plate 33 is slidably connected to the connecting tube 3, and the second moving plate 33 is embedded with a rolling ball. The left side of the lower part of the connecting tube 3 is rotatably connected with a connecting shaft 34, and the connecting shaft 34 is connected to the rotating shaft of the switch 4 through a universal joint. During the rotation process, the switch 4 drives the connecting shaft 34 to rotate synchronously through the transmission of the universal joint. The connecting shaft 34 is provided with an arc groove that slidably cooperates with the rolling ball on the second moving plate 33. During the rotation process, the connecting shaft 34 drives the second moving plate 33 to move up and down, and then drives the moving ring 32 to move up and down. The angle of the rotation path of the arc groove on the upper part of the connecting shaft 34 is 360°, and the vertical height of the arc groove on the connecting shaft 34 is the same as the height of the moving ring 32, ensuring that the second moving plate 33 can drive the moving ring 32 to move upward to the limit position synchronously when it moves upward to the limit position. The fixed part of the hydraulic telescopic rod 22 is fixedly connected with a sealing block 35, and the right side of the bracket 1 is fixedly connected with a liquid storage pipe 36. The sealing block 35 and the liquid storage pipe 36 are sealed and slidably connected. The upper side of the sealing block 35 and the liquid storage pipe 36 are filled with hydraulic oil. The liquid storage pipe 36 and the liquid storage ring 31 are connected through a connecting pipe. The connecting pipe is located at the lower side of the sealing block 35. When the moving ring 32 moves upward, the hydraulic oil inside the liquid storage ring 31 is transported to the liquid storage pipe 36 through the connecting pipe, so that the sealing block 35 moves upward, thereby changing the position of the fixed part of the hydraulic telescopic rod 22.

[0035] When using this device, the staff places the glass slide between the two fixtures 9, then places the two fixtures 9 and the glass slides thereon on the first first moving block 8, and adjusts them to a suitable position, then the control terminal starts the electric rotating shaft 501, and the electric rotating shaft 501 drives the fixed plate 6 to rotate, and adjusts the position of the first glass slide thereon, until the first glass slide rotates 90°, the control terminal shuts down the electric rotating shaft 501, and places the second glass slide on the second first moving block 8 according to the above operation, then the control terminal continues to start the electric rotating shaft 501 according to the above operation, until the electric rotating shaft 501 rotates 270°, and glass slides are placed on the four first moving blocks 8.

[0036] After the electric shaft 501 rotates 270°, the control terminal turns off the electric shaft 501 and starts the driving device at the same time, and the driving device drives the first movable plate 2 to move downward, and the first movable plate 2 drives the connecting tube 3 to move downward, and the connecting tube 3 drives the switch 4 and the objective lens thereon to move downward synchronously to adjust the focal length of the objective lens to a suitable state. After the focal length of the objective lens is adjusted, the control terminal turns off the driving device and starts the electronic light source at the same time, and adjusts the electronic light source so that the electronic light source can be focused on the objective lens. Then the control terminal starts the shooting device, and the shooting device scans and shoots the sample on the glass slide. During the scanning process, the control terminal changes the position of the fixed disk 6 through the electric slider 5, and then fine-tunes the position of the glass slide to ensure that the objective lens can fully cover the sample during the scanning process of the shooting device on the sample on the glass slide.

[0037] After the scanning of the sample on the glass slide is completed, the control terminal turns off the shooting device and the electronic light source and starts the driving device in reverse, and the driving device drives the first movable plate 2 and other parts connected thereto to reset upward, and the control terminal continues to start the electric rotating shaft 501 (with Figure 1 The electric rotating shaft 501 rotates clockwise), and after the scanned glass slide is transported for 90°, the control terminal shuts down the electric rotating shaft 501 again, and the staff replaces the scanned glass slide and continues to scan the remaining glass slides according to the above operation.

[0038] In the process of the fixed disk 6 driving the first movable block 8 to rotate, the first movable block 8 drives the two adjacent second connecting blocks 23 to rotate synchronously. After the two second connecting blocks 23 on the front side rotate 270°, the two second connecting blocks 23 on the front side rotate to the right side, and the arc grooves on the lower sides of the two second connecting blocks 23 contact the adjacent fixed blocks 27 respectively.

[0039] In the process of the above-mentioned control terminal adjusting the position of the connecting tube 3 through the driving device, when the first movable plate 2 moves downward to the position in contact with the first connecting block 21, the first movable plate 2 drives the first connecting block 21 to move downward synchronously, and the first connecting block 21 drives the telescopic end of the hydraulic telescopic rod 22 to move downward synchronously, so that the telescopic end of the hydraulic telescopic rod 22 retracts into its fixed part, and the hydraulic oil in its fixed part is transported to the two fixed pipes 24 through the connecting pipe.

[0040] The hydraulic oil delivered to the fixed pipe 24 flows between it and the adjacent push plate 25, so that the push plate 25 is squeezed by the adjacent hydraulic oil and moves downward, and the adjacent second elastic member 251 is stretched and stored, and the push plate 25 drives the adjacent moving rod 26 to move downward synchronously, and the moving rod 26 drives the adjacent fixed block 27 to move downward, and the fixed block 27 drives the adjacent second connecting block 23 to move downward, and the second connecting block 23 drives the adjacent first moving block 8 to move downward, and at the same time compresses the two adjacent first elastic members 10, and the first moving block 8 drives the glass slide thereon to move downward synchronously, and at this time, the downward movement speed of the first moving block 8 is the same as the downward movement speed of the connecting tube 3, that is, the downward movement speed of the glass slide is the same as the downward movement speed of the connecting tube 3, so as to avoid the objective lens being unable to focus due to damage or debris attached thereto during the downward movement of the connecting tube 3, causing the connecting tube 3 to continue to move downward, so that the objective lens on the switcher 4 squeezes the glass slide, causing the glass slide to break.

[0041] When the first movable plate 2 contacts the first connecting block 21 (the first connecting block 21 is at the initial position at this time, and when the first movable plate 2 moves downward to the position in contact with the first connecting block 21, the objective lens of the switch 4 moves synchronously to the position in contact with the glass slide, which is the safety position for the switch 4 to move downward), the value detected by the pressure sensor on the first connecting block 21 increases, and the control terminal issues an alarm to remind the staff that the distance the connecting tube 3 moves downward is too large, and the staff shuts down the device, inspects the device, and removes the glass slides on the four first movable blocks 8. Under, until the maintenance of the device is completed, the staff resets the connecting cylinder 3 to the initial position. During the resetting process of the connecting cylinder 3, the squeezing force of the first movable plate 2 on the first connecting block 21 is gradually reduced, so that the pulling force on the two second elastic members 251 is gradually reduced synchronously, and then the two second elastic members 251 are gradually reset to the initial state, and drive the adjacent push plates 25 and other parts connected thereto to reset to the initial position synchronously, and the push plate 25 re-transports the hydraulic oil between it and the adjacent fixed pipe 24 to the fixed part of the hydraulic telescopic rod 22, so that the telescopic end of the hydraulic telescopic rod 22 drives the first connecting block 21 to reset to the initial position.

[0042] In the process of scanning the sample on the glass slide using the device, when it is necessary to switch the high-power objective lens, the staff rotates the switch 4 according to the type of sample to switch the objective lens of the appropriate power. During the rotation of the switch 4, the rotating shaft of the switch 4 drives the connecting shaft 34 to rotate through the universal joint. The second moving plate 33 is limited by the arc groove on the connecting shaft 34 and moves upward with the rotation of the connecting shaft 34. The second moving plate 33 drives the moving ring 32 to move upward synchronously, so that the moving ring 32 moves into the liquid storage ring 31 and the liquid in the liquid storage ring 31 is filled. The hydraulic oil is squeezed into the liquid storage tube 36 through the connecting tube, so that the volume of the hydraulic oil between the liquid storage tube 36 and the sealing block 35 increases, thereby causing the sealing block 35 to move upward, and the sealing block 35 drives the fixed part of the hydraulic telescopic rod 22 to move upward synchronously, and the telescopic end of the hydraulic telescopic rod 22 drives the first connecting block 21 to move upward synchronously, and the position of the first connecting block 21 is adjusted, that is, the distance between the first connecting block 21 and the first movable plate 2 is adjusted, and then the safety position of the objective lens moving downward is adjusted to avoid affecting the focusing process of the high-magnification objective lens.

[0043] At present, when using a pathology scanner, the staff only places the glass slide in the groove on the stage without effectively fixing the glass slide, which makes the glass slide easily shaken by the outside world during the movement, thereby affecting the film quality of the scanner. In this regard, the present invention avoids the above situation through the following operations:

[0044] Example 2: Based on Example 1, please combine Figure 2 and Figure 7-10 Reading this paragraph, it also includes a limit ring 42, the lower side of the inner part of the limit ring 42 is set to be stepped, and the limit ring 42 is divided into two steps (with the tangent point on the right side of the limit ring 42 as the reference point, and Figure 2The top view angle is the reference angle, the limiting ring 42 is provided with a notch at the position of 45°-135° clockwise from the reference point, the limiting ring 42 is the first step at the position of 135°-225° from the reference point, and is the second step at the position of 225°-45°, and the height of the lower side of the first step is greater than the height of the lower side of the second step), the limiting ring 42 is fixedly connected to the electric slider 5, the limiting ring 42 is rotatably connected to the fixed disk 6, the first moving block 8 is slidably connected with symmetrically distributed extrusion blocks 43, the fixed disk 6 drives the extrusion block 43 to rotate through the transmission of the first moving block 8, the extrusion block 43 is extruded and matched with the limiting ring 42, and the extrusion block 43 moves downward due to the extrusion of the step position on the limiting ring 42 during the rotation process, the first moving block 8 is internally slidably connected with a symmetrically distributed second moving block 44, the second moving block 44 is extruded and matched with the adjacent extrusion block 43, and the extrusion block 43 is extruded in the process of moving downward During the process, the adjacent second moving block 44 is driven to move synchronously, and two symmetrically distributed elastic telescopic rods 45 are fixedly connected to one side of the second moving block 44 close to the adjacent fixer 9, and the telescopic end of the elastic telescopic rod 45 is fixedly connected with a push plate 46, and the push plate 46 contacts and cooperates with the adjacent fixer 9. The second moving block 44 drives the adjacent push plate 46 to move synchronously through the transmission of the adjacent elastic telescopic rod 45, and then pushes the center of the two adjacent fixers 9 and the glass slides connected thereto to a position coincident with the center of the adjacent first moving block 8. The elastic coefficient of the first elastic member 10 is greater than the sum of the elastic coefficients of the two adjacent elastic telescopic rods 45, and is used for when the extrusion block 43 contacts the first step on the limit ring 42, the extrusion block 43 moves downward to drive the adjacent second moving block 44 to move, and when the extrusion block 43 contacts the second step on the limit ring 42, the extrusion block 43 drives the adjacent first moving block 8 to move downward synchronously.

[0045] Please combine Figure 8-Figure 10 Reading this paragraph, the first moving block 8 is rotatably connected to four L-shaped plates 51 distributed in a matrix, and a third elastic member 52 is arranged between the L-shaped plate 51 and the adjacent first moving block 8. The third elastic member 52 is a torsion spring. The third elastic member 52 is used to maintain the initial position of the adjacent L-shaped plate 51 and drive the L-shaped plate 51 to reset to the initial position after moving. The L-shaped plate 51 is squeezed and matched with the adjacent fixer 9, and the L-shaped plate 51 is limited and matched with the fixed disk 6. In the process of the first moving block 8 moving downward, the first moving block 8 drives the four adjacent L-shaped plates 51 to move downward synchronously, so that the four adjacent L-shaped plates 51 are limited and rotated by the fixed disk 6. After the L-shaped plate 51 rotates 90°, the L-shaped plate 51 squeezes the adjacent fixer 9, and the four L-shaped plates 51 cooperate with each other to fix the two adjacent fixers 9, and then fix the adjacent glass slides.

[0046] Please combine Figure 8 and Fig. 9Reading this paragraph, a storage shell 61 is fixedly connected to the lower side of the first movable block 8, and the through hole on the first movable block 8 is connected to the adjacent storage shell 61. The lower side inside the storage shell 61 is set to be convex, and the storage shell 61 is made of glass to increase the light-gathering property of the storage shell 61. The storage shell 61 is used to store broken glass slides to prevent pathological samples on the glass slides from leaking after the glass slides are broken.

[0047] In the process of the fixed plate 6 driving the four first moving blocks 8 thereon to rotate, the following is described by taking the rotation process of the front first moving block 8 as an example:

[0048] The first moving block 8 drives the two adjacent squeezing blocks 43 to move synchronously during the rotation process. When the left squeezing block 43 of the two front squeezing blocks 43 rotates to a position in contact with the first step on the limiting ring 42, the left squeezing block 43 moves downward due to the squeezing of the limiting ring 42 as it continues to move. During the downward movement of the left squeezing block 43, the left squeezing block 43 squeezes the adjacent second moving block 44, causing the second moving block 44 to move to the right, and drives the two adjacent elastic telescopic rods 45 to move to the right synchronously. The telescopic ends of the two elastic telescopic rods 45 jointly drive the adjacent push plates 46 to move to the right. The push plates 46 drive the adjacent glass slides to move to the right synchronously through the transmission of the adjacent fixers 9, until the left squeezing block 43 stops moving downward, and the adjacent glass slides stop moving to the right synchronously.

[0049] When the right squeezing block 43 moves to the position in contact with the limiting ring 42, the right squeezing block 43 drives the adjacent glass slide to move synchronously to the left, and the two squeezing blocks 43 cooperate with each other to adjust the position of the adjacent glass slide, so that the glass slide moves to the middle of the adjacent first moving block 8.

[0050] When the squeezing block 43 on the left side rotates to the position in contact with the second step on the limiting ring 42 (at this time, the first moving block 8 on the front side has rotated 90° clockwise, and the glass slide on the front side is located at the left rear part of the fixed plate 6), the left squeezing block 43 continues to move downward due to the squeezing of the second step on the limiting ring 42, and at the same time, the left squeezing block 43 drives the adjacent first moving block 8 and other parts connected thereto to move downward synchronously. At this time, the first moving block 8 drives the four adjacent L-shaped plates 51 to move downward synchronously. In the process of the L-shaped plate 51 moving downward, the L-shaped plate 51 is limited by the fixed plate 6 and rotates, so that the vertical surface of the L-shaped plate 51 rotates to the horizontal plane and contacts the adjacent fixer 9. The adjacent two L-shaped plates 51 cooperate with the adjacent first moving blocks 8 to clamp the adjacent fixer 9, and then fix the adjacent fixer 9 to fix the adjacent glass slide, so as to prevent the position of the glass slide from changing during the scanning process, affecting the scanning result of the sample on the glass slide.

[0051] During the downward movement of the above-mentioned first moving block 8, the first moving block 8 drives the extrusion block 43 on the right to move downward synchronously, and compresses the two adjacent first elastic members 10 until the extrusion block 43 on the right contacts the second step on the limiting ring 42, and the fixed disk 6 has rotated 180° (at this time, the glass slide on the front side rotates to the rear side and is fixed), until the fixed disk 6 rotates 270° (at this time, the glass slide on the front side rotates to the right side), the control terminal shuts down the electric shaft 501, and scans the glass slide on the right side at this time according to the above operation, and the movement process of the remaining extrusion blocks 43 can refer to the above.

[0052] In the above process of scanning the sample rotated to the right glass slide, the light source at the bottom of the device passes through the bottom of the adjacent storage shell 61 and is collected by the tapered portion at the bottom of the adjacent storage shell 61, so that the light source can be quickly collected.

[0053] In the process of the above-mentioned fixed plate 6 driving the glass slide to rotate through the first moving block 8, if the glass slide is broken due to external influences, the broken glass slide falls downward into the adjacent storage shell 61, and at the same time, the two adjacent fixers 9 are respectively subjected to the squeezing force of the adjacent elastic telescopic rods 45, and respectively drive the remaining glass slides thereon to move toward the direction close to the middle of the adjacent storage shell 61, until the two fixers 9 are respectively moved to the position matching the through holes on the first moving block 8, and the fixers 9 drive the remaining glass slides thereon to fall downward into the adjacent storage shell 61, and the storage shell 61 stores the broken glass slides to prevent the broken glass slides from affecting the inspection and scanning of the remaining intact glass slides, and to prevent the pathological samples on the glass slides from leaking after the glass slides are broken, which affects the sterile environment of the device.

[0054] When the broken glass slides are rotated to the front side again, the staff will replace the storage shell 61 storing the broken glass slides and clean the glass slides in the storage shell 61 for next use.

[0055] While the disclosure has been described with respect to only a limited number of embodiments, those skilled in the art, having benefit of this disclosure, will appreciate that numerous other embodiments can be devised which do not depart from the scope of the invention.
