Description

Technical Field

[0001] The present invention relates to the field of medical detection technology, and in particular to a pathological slice scanner lens driving device and a use method thereof. Background Art

[0002] Pathology slide scanner is a highly specialized medical device used to convert traditional pathology glass slides into high-resolution digital images for pathologists and researchers to observe, analyze and archive on computers. It plays a core role in the field of digital pathology and greatly promotes remote diagnosis, teaching, research and information management of pathology departments.

[0003] When scanning with a pathology slide scanner, the glass slide containing the pathology slide needs to be placed on the stage under the microscope lens, and the drive device is used to adjust the microscope lens to move down and to a suitable position above the glass slide. The position of the glass slide is adjusted by moving the stage to perform a full-scale scan of the pathology slide.

[0004] When a pathology slice scanner is scanning a glass slide, it is necessary to make the microscope lens face the glass slide. If the microscope lens is not facing the glass slide, the imaging focus will deviate, causing the scanned image to become blurred and causing geometric distortion of the image. During long-term use of the driving device, the position of the microscope lens will deviate, which will prevent the microscope lens from facing the glass slide. If the glass slide is not placed horizontally on the stage, the microscope lens will also not face the glass slide. The existing driving device of the pathology slice scanner can generally only adjust the height of the microscope lens, and cannot automatically adjust the position of the microscope lens at multiple angles. Manual adjustment and correction are required. Therefore, the existing driving device has a poor driving effect on the microscope lens. To this end, we propose a pathology slice scanner lens driving device and a method for using it. Summary of the invention

[0018] A method for using a lens driving device for a pathological slice scanner comprises the following steps:

[0019] S1. Place the slide containing the pathological section under the microscope head, adjust the lifting assembly, lower the height of the microscope head, and bring the microscope head close to the slide;

[0020] S2. Use an optical autocollimator to check whether the microscope lens is facing the slide;

[0021] S3, when it is detected that the microscope head is not facing the glass slide, all electric cylinders are started, and each electric cylinder drives the two ball sleeves to move horizontally by pushing and pulling the corresponding transmission components, so that the spherical shaft tube rotates inside the two ball sleeves, so that the microscope head is deflected accordingly;

[0022] In S3, when the electric cylinder pushes and pulls the transmission component, the soft pad is tightly pressed against the first ball above the transmission component.

[0023] The present invention has the following beneficial effects:

[0024] 1. The present invention starts the electric cylinder to push or pull the corresponding transmission components to drive the two ball sleeves to move in the horizontal direction, so that the spherical shaft tube rotates inside the two ball sleeves. According to the verticality error, the microscope lens is deflected and adjusted accordingly until the microscope lens is facing the glass slide, thereby realizing automatic adjustment of the position of the microscope lens, so that the microscope lens can be aligned with the glass slide, which can avoid the problems of geometric distortion of the image and blurring of the image caused by the misalignment of the microscope lens and the glass slide. The design structure is very simple and convenient for adjusting and fixing the position of the microscope lens.

[0025] 2. In the present invention, when the electric cylinder pushes and pulls the transmission assembly, the cushion is tightly pressed against the first ball on the top of the transmission assembly, and the first ball on the bottom of the transmission assembly is pressed against the bottom of the limit frame, which limits the movement direction of the transmission assembly, ensures that the transmission assembly and the ball sleeve only move in the horizontal direction, and prevents the transmission assembly from deviating from the trajectory, resulting in reduced adjustment accuracy. The structure of the first ball arranged above and below the transmission assembly can prevent the transmission assembly from contacting the limit frame and the cushion, making the transmission assembly easier to move, so that the electric cylinder is not easily obstructed in adjusting the ball sleeve position through the transmission assembly.

[0026] 3. In the present invention, the ball head can roll at multiple angles in the ball seat, so that the microscope lens installed at the bottom of the connecting shaft block can be deflected at multiple angles, thereby enabling the microscope lens to be corrected and adjusted at multiple angles. Under the structural coordination of the connecting assembly, when the two ball sleeves are moved in the horizontal direction, the position of the spherical shaft tube can be changed by sliding the spherical shaft tube in the two ball sleeves, thereby enabling the position of the microscope lens to be changed. In this process, the microscope lens always deflects along the center of the ball head, which means that when the positions of the two ball sleeves are fixed, the positions of the spherical shaft tube and the microscope lens are fixed.

DETAILED DESCRIPTION

[0040] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0041] Example:

[0042] See also Figure 1-10 As shown, a lens driving device for a pathological slice scanner comprises a mounting seat 1, a lifting assembly 4 for adjusting the height of a microscope lens 2 is fixedly arranged at the bottom of the mounting seat 1, a connecting assembly 5 for mounting the microscope lens 2 is arranged at the bottom of the lifting assembly 4, a positioning assembly 6 is arranged on the side of the microscope lens 2, a plurality of evenly spaced adjustment assemblies 7 are fixedly arranged below the side of the lifting assembly 4, and an optical autocollimator 18 is fixedly arranged below the side of the microscope lens 2;

[0043] In this device, the optical autocollimator 18 is used to detect whether the microscope lens 2 is facing the glass slide. When in use, the optical autocollimator 18 emits a beam of laser or light, forms a beam of collimated light through the internal collimating lens system, and projects the beam onto the glass slide. When the beam returns and converges again on the graticule plate inside the optical autocollimator 18 and coincides with the starting point, it can be determined that the beam is perpendicular to the plane. If the beam is not perpendicular to the plane, the verticality error can be quantitatively analyzed by reading the scale on the graticule plate.

[0044] The connecting assembly 5 includes a ball seat 51 fixedly arranged below the lifting assembly 4, a ball head 52 movably arranged inside the ball seat 51, and a connecting shaft block 53 fixedly connected to the ball head 52, and the microscope lens 2 is fixedly installed at the bottom of the connecting shaft block 53;

[0045] Based on this structure, the ball head 52 can roll at multiple angles in the ball seat 51, so that the microscope lens 2 installed at the bottom of the connecting shaft block 53 can be deflected at multiple angles, thereby enabling the microscope lens 2 to be corrected and adjusted at multiple angles.

[0046] The positioning assembly 6 includes a spherical shaft tube 61 fixedly arranged on the side of the microscope lens 2, and two ball sleeves 62 movably arranged on the spherical surface of the spherical shaft tube 61. The two ball sleeves 62 are fixedly connected to each other and slide on the spherical surface of the spherical shaft tube 61.

[0047] Based on this structure, with the structural cooperation of the connecting assembly 5, when the two ball sleeves 62 are moved in the horizontal direction, the position of the spherical shaft tube 61 can be changed by sliding the spherical shaft tube 61 in the two ball sleeves 62, so that the position of the microscope lens 2 can be changed. In this process, the microscope lens 2 is always deflected along the center of the ball head 52, which makes it possible that when the positions of the two ball sleeves 62 are fixed, the positions of the spherical shaft tube 61 and the microscope lens 2 are fixed.

[0048] The adjusting assembly 7 includes a mounting module 71 fixedly arranged on the side of the lifting assembly 4, an electric cylinder 72 and a limit frame 73 fixedly arranged on the mounting module 71, a transmission assembly 74 movably arranged inside the limit frame 73, a first ball 75 arranged on the transmission assembly 74, and a cushion 76 fixedly arranged on the top of the inner side of the limit frame 73. The transmission assembly 74 is rolled with evenly spaced first balls 75 on the upper and lower sides. The first ball 75 at the lower side of the transmission assembly 74 is pressed on the inner bottom of the limit frame 73. The first ball 75 at the upper side of the transmission assembly 74 is in conflict with the cushion 76. One end of the transmission assembly 74 is movably connected to the output end of the electric cylinder 72, and the other end of the transmission assembly 74 is movably connected to the sides of the two ball sleeves 62.

[0049] Based on this structure, when the electric cylinder 72 pushes and pulls the transmission assembly 74, the cushion 76 is tightly pressed on the first ball 75 above the transmission assembly 74, and the first ball 75 below the transmission assembly 74 is pressed on the bottom of the limit frame 73, which restricts the movement direction of the transmission assembly 74, ensuring that the transmission assembly 74 and the ball sleeve 62 only move in the horizontal direction, and preventing the transmission assembly 74 from deviating from the trajectory and causing a decrease in adjustment accuracy. The structure of the first ball 75 arranged above and below the transmission assembly 74 can prevent the transmission assembly 74 from contacting the limit frame 73 and the cushion 76, making the transmission assembly 74 easier to move, so that the electric cylinder 72 is not easily obstructed in adjusting the position of the ball sleeve 62 through the transmission assembly 74.

[0050] In the use of the pathology section scanner, in order to solve the problem of the inconvenience of multi-angle position adjustment of the microscope lens 2 when driving the microscope lens 2 in the existing scanner, the present structure detects the alignment of the microscope lens 2 and the glass slide. In the case of misalignment, the electric cylinder 72 is started to push or pull the corresponding transmission assembly 74 to drive the two ball sleeves 62 to move in the horizontal direction, so that the spherical shaft tube 61 rotates inside the two ball sleeves 62. According to the verticality error, the microscope lens 2 is deflected and adjusted accordingly until the microscope lens 2 is facing the glass slide, realizing the multi-angle automatic adjustment of the position of the microscope lens 2, so that the microscope lens 2 can be aligned with the glass slide, which can avoid the problem of geometric distortion of the image caused by the misalignment of the microscope lens 2 and the glass slide, and the image becomes blurred. The present design structure is very simple and convenient for adjusting and fixing the position of the microscope lens 2.

[0051] Among them, the lifting component 4 includes a power cylinder 41 fixedly installed at the bottom of the mounting base 1, and a stabilizing platform 42 fixedly arranged at the bottom output end of the power cylinder 41. A bottom groove 3 is opened at the bottom of the stabilizing platform 42, and a ball seat 51 is fixedly installed inside the bottom groove 3.

[0052] Based on this structure, the power cylinder 41 is a hydraulic cylinder or an electric cylinder, and the power cylinder 41 is used to adjust the height of the stable platform 42 to adjust the distance between the microscope lens 2 and the glass slide.

[0053] The inner wall of the ball seat 51 is fixedly provided with an anti-skid inner layer 8 , the inner side surface of the anti-skid inner layer 8 is a spherical surface, and the inner diameter of the anti-skid inner layer 8 is smaller than the diameter of the ball head 52 .

[0054] Based on this structure, the anti-skid inner layer 8 is a rubber anti-skid pad, and the anti-skid inner layer 8 and the ball head 52 are interference-fitted. The ball head 52 squeezes the anti-skid inner layer 8, so that the ball head 52 is not easy to rotate inside the anti-skid inner layer 8. This also makes it difficult for the connection state of the ball head 52 in the anti-skid inner layer 8 to be disturbed without adjustment, making the device more anti-interference and improving the stability of the device. In addition, the setting of the anti-skid inner layer 8 separates the ball head 52 and the ball seat 51, so that the ball head 52 and the ball seat 51 will not be damaged by friction. The setting of the anti-skid inner layer 8 ensures that when the ball head 52 and the ball seat 51 expand and contract with heat, the rotation of the ball head 52 will not be disturbed by the adaptive deformation of the anti-skid inner layer 8. The problem that the ball head 52 and the ball seat 51 are easily worn and the accuracy is greatly reduced after the expansion and contraction without the anti-skid inner layer 8 is solved. The anti-slip inner layer 8 also has the function of absorbing energy, which can reduce the vibration effect of the ball seat 51 on the ball head 52, thereby effectively improving the anti-interference ability of the microscope lens 2.

[0055] Among them, the outer spherical diameter of the spherical shaft tube 61 is smaller than the diameter of the inner spherical diameter of the ball sleeve 62. The outer spherical surface of the spherical shaft tube 61 is provided with a plurality of evenly spaced notches 9. A second ball 10 is movably arranged inside each notch 9, and each second ball 10 is against the inner spherical surface of the ball sleeve 62.

[0056] Based on this structure, by using the second ball 10 to contact the ball sleeve 62, the relative movement between the spherical shaft tube 61 and the ball sleeve 62 can be made more convenient, avoiding the problem of easy wear when the spherical shaft tube 61 and the ball sleeve 62 are in direct contact.

[0057] Among them, the two ball sleeves 62 are distributed vertically, a limiting ring 11 is integrally arranged at the bottom of the upper ball sleeve 62, a limiting groove 12 matching the limiting ring 11 is opened on the top of the lower ball sleeve 62, the limiting ring 11 is engaged in the limiting groove 12, and a plurality of connecting plates 13 are fixedly arranged on the sides of the two ball sleeves 62, the connecting plates 13 on the upper ball sleeve 62 correspond to the connecting plates 13 on the lower ball sleeve 62 one by one, and the two corresponding connecting plates 13 are fixed by bolts 14.

[0058] Based on this structure, the arrangement of the limiting ring 11 and the limiting groove 12 makes the connection between the upper and lower ball sleeves 62 smoother. The corresponding connecting plates 13 are fixed with bolts 14 to facilitate the installation and fixing of the upper and lower ball sleeves 62 together.

[0059] The transmission assembly 74 includes a cylinder 741, a movable shaft 742, a first connecting frame 743, a second connecting frame 744, a spring 745, and a butt plate 746. Two chambers 15 are provided in the cylinder 741. A spring 745, a movable shaft 742, and a butt plate 746 are provided inside each chamber 15. The butt plate 746 is fixedly provided on the outer side of the movable shaft 742. The spring 745 is sleeved on one end of the movable shaft 742. One end of the spring 745 is in contact with the butt plate 746, and the other end of the spring 745 is in contact with the inner wall of the chamber 15. The other end passes through the cylinder body 741 and is fixedly connected to the first connecting frame 743. The first connecting frame 743 is located at one end of the cylinder body 741. The second connecting frame 744 is fixedly installed at the other end of the cylinder body 741. The second connecting frame 744 is movably connected to the output end of the electric cylinder 72. A plurality of clamping plates 17 are fixedly arranged on the sides of the two ball sleeves 62. The clamping plates 17 on the upper ball sleeve 62 correspond to the clamping plates 17 on the lower ball sleeve 62. The first connecting frame 743 is engaged between the two corresponding connecting plates 13. The first ball 75 is rollingly arranged on the upper and lower parts of the cylinder body 741. The first connecting frame 743 and the second connecting frame 744 are both installed horizontally.

[0060] Based on this structure, the arrangement of the two movable shafts 742 makes the movement of the first connecting frame 743 more stable. The arrangement of the spring 745 and the abutment plate 746 on the movable shaft 742 can buffer the movable shaft 742, reduce the unstable force on the movable shaft 742, so that when the device is disturbed by external vibration, the force on the movable shaft 742 is not easy to fluctuate, which can minimize the vibration of the microscope, avoid affecting the image clarity, and ensure higher scanning quality.

[0061] Each chamber 15 is filled with damping fluid, and the inner side surface of the abutment plate 746 is provided with a plurality of openings 16 evenly spaced apart.

[0062] Based on this structure, the damping fluid has an obstructive effect on the movement of the movable shaft 742 and can further absorb the energy received by the movable shaft 742, thereby reducing the vibration of the movable shaft 742, making the microscope head 2 indirectly connected to the movable shaft 742 less susceptible to interference.

[0063] The mounting module 71 includes a horizontal axis 711 fixedly mounted on the side of the stable platform 42, a first vertical axis 712 and a second vertical axis 713 fixedly mounted at the bottom of the horizontal axis 711, and a horizontal plate 714 fixedly mounted at the bottom of the first vertical axis 712 and the second vertical axis 713. The electric cylinder 72 and the limiting frame 73 are fixedly mounted above the horizontal plate 714, the limiting frame 73 is fixedly mounted at the bottom of the first vertical axis 712, and the electric cylinder 72 is fixedly mounted on the side of the second vertical axis 713.

[0064] A method for using a lens driving device for a pathological slice scanner comprises the following steps:

[0065] S1, placing a glass slide carrying pathological sections under the microscope lens 2, adjusting the lifting assembly 4, lowering the height of the microscope lens 2, and bringing the microscope lens 2 close to the glass slide;

[0066] S2, using the optical autocollimator 18 to detect whether the microscope lens 2 is facing the glass slide;

[0067] S3, when it is detected that the microscope head 2 is not facing the glass slide, all the electric cylinders 72 are started, and each electric cylinder 72 drives the two ball sleeves 62 to move horizontally by pushing and pulling the corresponding transmission assembly 74, so that the spherical shaft tube 61 rotates inside the two ball sleeves 62, so that the microscope head 2 is deflected accordingly;

[0068] In S3 , when the electric cylinder 72 pushes and pulls the transmission assembly 74 , the cushion 76 is tightly pressed against the first ball 75 above the transmission assembly 74 .
