Description

Technical Field

[0001] The present invention relates to the technical field of pathological slices, and in particular to a slice processing device for pathological digital slice analysis. Background Art

[0002] The slice processing device for pathological digital slice analysis is a key device for preparing tissue sample slices in medical laboratories. It cuts biological tissue into thin slices through fine mechanical operations for pathological observation and research under a microscope. The device usually includes a sample clamping system, a slicer, a pusher, a control panel, and a waste slice collector. The device can cut fixed tissue blocks into thin slices of uniform thickness, providing accurate diagnostic basis for pathologists, and plays a vital role in ensuring the quality of pathological slices, improving the accuracy of pathological diagnosis, and improving research efficiency.

[0003] Traditional slicers are widely used in the medical field, but due to the limitations of their structure and working principle, there are often some problems that cannot be ignored. For example, when slicing samples, traditional slicers need to manually assist in stretching and unfolding the sample slices to avoid the inconvenience of sample sampling caused by the accumulation of slices, which has high requirements on the experience and operating ability of the staff. After the existing slicers cut the samples, the edges of the slices cut are connected. The staff needs to first place the interconnected slices on the water surface to suspend them, and then use tweezers and other tools to pull the connection of the slices to separate the connected parts of the slices from each other. Each slice needs to be separated. The operation is cumbersome and it is easy to damage the integrity of the slices. After separating the slices, the staff needs to hold an empty slide and fish the separated slices out of the water, which affects the efficiency of the slicing and sampling operation.

[0037] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific implementation methods of the present invention are described in detail below in conjunction with the accompanying drawings.

[0038] Example 1, reference Figure 1-Figure 16 , which is the first embodiment of the present invention, provides a slice processing device for pathological digital slice analysis, including a slicer body 1, a base fixedly connected to the slicer body 1 for fixing samples, a fixing frame 2 fixedly connected to the top of the base, a support plate 3 arranged in the middle of the base, a blade 4 fixedly connected to the top of the support plate 3, and a water tank 5 fixedly connected to the middle of the base, and also includes a rotating mechanism 6 fixedly connected to the bottom of the fixing frame 2, a separating mechanism 7 fixedly connected to the middle of the support plate 3, and a slice catching mechanism 8 fixedly connected to the bottom of the support plate 3; the rotating mechanism 6 includes a pull rod 61 fixedly connected to the bottom of the fixing frame 2, a cable 62 fixedly connected to the bottom end of the pull rod 61, a roller 63 rotatably connected to the middle of the support plate 3, a sleeve 64 fixedly connected to the end of the cable 62 away from the pull rod 61, a damping plate 65 rotatably connected to the end of the sleeve 64 away from the roller 63, and a bracket 66 rotatably connected to the end of the damping plate 65 away from the sleeve 64. Six annular arrays are fixedly connected to the support shaft 67 at one end of the sleeve 64 near the roller 1 63, the pawl 68 is rotatably connected to the outside of the support shaft 67, the spring 1 69 is fixedly connected to the outer wall of the pawl 68, the two ends of the spring 1 69 are respectively fixedly connected to the inner wall of the sleeve 64 and the outer wall of the pawl 68, the spring 610 is fixedly connected to the end of the sleeve 64 near the pawl 68, the bracket 2 611 is rotatably connected to the outside of the sleeve 64, and the two ends of the spring 610 are respectively connected to the outer wall of the sleeve 64 It is fixedly connected to the inside of bracket two 611, fixedly connected to a cross bar 612 on the side of bracket two 611 close to the pull rod 61, rotatably connected to a pulley 613 at an end of the cross bar 612 away from bracket two 611, rotatably connected to a rotating shaft 614 inside a sleeve 64, and fixedly connected to an end of the rotating shaft 614 away from the damping plate 65, the end of the ratchet 615 away from the rotating shaft 614 is fixedly connected to roller one 63, and the outer side of the roller is slidably connected to the middle part of the cable 62.

[0039] Specifically, by controlling the fixed frame 2 to move up and down, a driving force can be provided for the rotating mechanism 6. The fixed frame 2 moves downward to drive the pull rod 61 to move downward, and the pull rod 61 pulls the cable 62 to drive the sleeve 64 to rotate. While the sleeve 64 rotates, the cooperation of the ratchet and the pawl 68 drives the rotating shaft 614 to rotate, and the rotating shaft 614 drives the roller 1 63 to rotate. While the roller 1 63 rotates, it will drive the cut slice to move toward the direction of the roller 2 71. Since the slice is moved by the roller 1 63 after being cut, it can avoid that multiple slices are piled up in the original place. While the sleeve 64 rotates, the spring 610 will store power. When the fixed frame 2 moves upward, it drives the pull rod 61 to move upward together and releases the tension on the cable 62. At this time, the spring 610 will release energy, driving the sleeve 64 to reverse. While the sleeve 64 reverses, the cable 62 is reeled in, and while the sleeve 64 reverses , driving the pawl 68 to move, and the pawl 68 is squeezed by the ratchet 615 to rotate, thereby releasing the engagement with the ratchet 615. The ratchet 615 and the rotating shaft 614 are constrained by the damping plate 65. When the force applied by the pawl 68 on the ratchet 615 is less than the friction between the damping plate 65 and the rotating shaft 614, the ratchet 615 will not rotate with the rotating shaft 614. Through the rotating mechanism 6, the pathology slicing device realizes the slicing unfolding and transportation functions, so that the device can automatically transfer the cut slices during the slicing process, avoiding the problems of accumulation and adhesion between slices, ensuring the integrity of the slices, reducing manual intervention, and improving the convenience and safety of experimental operations. It not only improves the automation degree of the pathology slicing device, but also improves the work efficiency, reduces the labor intensity of the operator, and provides support for the standardized and efficient operation of the pathology laboratory.

[0040] Reference Figure 12-13 The separation mechanism 7 includes a roller 71 rotatably connected to the bottom of the support plate 3, a gear 72 fixedly connected to the end of the roller 71 close to the ratchet 615, a driven wheel 73 fixedly connected to the end of the gear 72 away from the roller 71, and a driving unit fixedly connected to the end of the driven wheel 73 away from the gear 72.

[0041] Specifically, the slices can be moved by the roller 2 71 so as to unfold and separate the slices.

[0042] Reference Figure 12-14 The driving unit includes a bracket three 74 rotatably connected to the end of the driven wheel 73 away from the gear 72, a driving wheel 75 meshingly connected to the side of the driven wheel 73 close to the shaft sleeve 64, a rotating rod 76 fixedly connected to the end of the driving wheel 75 close to the cable 62, an annular groove 77 provided at the end of the rotating rod 76 close to the driving wheel 75, a bracket four 78 rotatably connected to the outside of the annular groove 77, a sliding sleeve 710 slidably connected to the outside of the rotating rod 76, a transmission component fixedly connected to the top of the rotating rod 76, and a supporting component fixedly connected to the side of the sliding sleeve 710 away from the rotating rod 76.

[0043] Specifically, the driving wheel 75 can transmit the force to the driven wheel 73, thereby achieving the lifting of the carrier 83.

[0044] Example 2, reference Fig.12 and Fig.16 , which is a second embodiment of the present invention, the transmission assembly includes a round pin 79 fixedly connected to the top of the rotating rod 76, a bracket 712 slidably connected to the outside of the sliding sleeve 710, and a driving groove 713 opened on the inner wall of the sliding sleeve 710, and the driving groove 713 is slidably connected to the round pin 79.

[0045] Specifically, the up and down movement of the inclined frame 715 can drive the sliding sleeve 710 to move, and the sliding sleeve 710 drives the driving wheel 75 to rotate.

[0046] Reference Figure 3 and Fig.12 The supporting assembly includes a sliding hole 714 opened at the end of the sliding sleeve 710 away from the rotating rod 76, an inclined frame 715 slidably connected to the inner side of the sliding hole 714, the top of the inclined frame 715 is fixedly connected to the bottom of the fixed frame 2, and a bracket six 716 that is rotatably connected to the end of the roller one 63 and the roller two 71 away from the gear 72.

[0047] Specifically, the fixed frame 2 moves downward while driving the inclined frame 715 downward, and the inclined frame 715 moves by squeezing the sliding sleeve 710. While the sliding sleeve 710 moves, the round pin 79 is squeezed through the driving groove 713. After the round pin 79 is subjected to force, it drives the rotating rod 76 to rotate. While the inclined frame 715 moves up and down, it drives the sliding sleeve 710 to reciprocate in the horizontal direction. Through the action of the driving groove 713, the reciprocating motion of the sliding sleeve 710 is converted into a directional rotation of the rotating rod 76. While the rotating rod 76 rotates, it drives the driving wheel 75 to rotate. The rotation of the driving wheel 75 drives the driven wheel 73 to rotate. The driven wheel 73 drives the gear 72 to rotate. The gear 72 drives the second roller 71 to rotate. While the second roller 71 rotates, the roller 1 63 slices the slices. The slices are transported to the position of roller 2 71, and the rotation speed of roller 2 71 is slightly higher than that of roller 1 63, so roller 2 71 transports the slices to the direction of slide 83, and while transporting, the rotation speed difference between roller 1 63 and roller 2 71 is used to pull the connected slices apart, so that the two adjacent slices are separated. Through the separation mechanism 7, the pathological slice device can separate the slices that are adhered to each other, simplifying the operation process. The mechanism can separate the slices one by one. This automated separation method reduces the manual operation steps and reduces the risk of slice damage caused by human error. The introduction of the separation mechanism 7 not only improves the preparation efficiency of pathological slices, but also ensures the slice quality, providing more reliable samples for subsequent pathological analysis.

[0048] Reference Fig.14 and Fig.15The film scooping mechanism 8 includes guide rails 81 symmetrically fixedly connected to both sides of the support plate 3, a lifting plate 82 slidably connected to the inner side of the guide rails 81, a film carrier 83 placed on the lifting plate 82 close to the support plate 3, a rack 84 fixedly connected to the lifting plate 82 close to the gear 72, and a return unit fixedly connected to the lifting plate 82 close to the rack 84.

[0049] Specifically, the guide rail 81 can constrain the movement trajectory of the lifting plate 82 and limit the maximum moving distance of the lifting plate 82 .

[0050] Reference Figure 4 and Fig.15 The return unit includes a spring 85 fixedly connected to the lifting plate 82 on the side close to the rack 84, and a slide 86 fixedly connected to the end of the spring 85 away from the rack 84. The two ends of the spring 85 are fixedly connected to the lifting plate 82 and the slide 86 respectively.

[0051] Specifically, spring 2 85 can push the lifting plate 82 to reset through its own elastic force. Through the slice catching mechanism 8, the pathological sectioning device realizes the movement of the slide and the catching of the slices, thereby improving the efficiency of slice catching. The automated slice catching operation not only reduces manual intervention, but also ensures the integrity and position consistency of the slices during the transfer process. The introduction of the slice catching mechanism 8 avoids slice damage and position deviation caused by manual operation, thereby improving the preparation quality and speed of pathological sections.

[0052] Reference Figure 6 and Fig.11 A through hole is formed at one end of the pulley 613 close to the cable 62 , and disc-shaped protrusions are formed at both ends of the pulley 613 .

[0053] Specifically, the pulley 613 cooperates with the crossbar 612 through the through hole, and the pulley 613 can rotate in accordance with the winding and unwinding of the cable 62 to reduce the wear of the cable 62. The remaining structure is the same as that of the first embodiment.

[0054] In summary, the working principle of the present invention is as follows: after the sample is clamped on the fixing frame 2, the fixing frame 2 is controlled to move downward, and the fixing frame 2 drives the sample downward. After the sample contacts the edge of the blade 4, the next slice is cut. After the slice is cut, it contacts the roller 63. By controlling the fixing frame 2 to move up and down reciprocatingly, the sample can be cut continuously. After the slice is cut, it will be in the shape of a strip with edges connected to each other. When the fixing frame 2 moves downward, it drives the pull rod 61 to move. The pull rod 61 pulls the cable 62. After the cable 62 is pulled, it drives the shaft sleeve 64 to rotate and unwind. When the shaft sleeve 64 rotates, the mainspring 610 will accumulate force, and the shaft sleeve 64 drives the support shaft 67 and the spring 69 to move together. The support shaft 67 drives the ratchet 68 connected thereto to move. The ratchet 68 moves due to the rotation of the support shaft 67. The ratchet 615 moves vertically along the edge of the ratchet 615, so it will be blocked by the ratchet 615, thereby driving the ratchet 615 to rotate together. After the ratchet 615 rotates, it drives the roller 1 63 to rotate. After the roller 1 63 rotates, it transports the slices in the direction of the roller 2 71. After being transported, the slices will be unfolded in a belt shape to avoid accumulation at the blade 4. When the fixed frame 2 moves up, it drives the pull rod 61 to move up. After the pull rod 61 moves up, the pulling of the cable 62 is released. At this time, the sleeve 64 will be reset under the action of the spring 610. While the sleeve 64 is reset, the cable 62 is reeled in, so that the cable 62 remains taut. While the sleeve 64 is reset, it drives the support shaft 67 to reset. The support shaft 67 drives the pawl 68 to move together. Due to the change in the rotation direction, the pawl 68 will be aligned with the arc of the edge of the ratchet 615. The pawl 68 is in contact with the surface, so the pawl 68 is squeezed by the ratchet 615, and rotates around the support shaft 67 and squeezes the spring 1 69, thereby releasing the meshing with the ratchet 615. The ratchet 615 and the rotating shaft 614 are constrained by the damping plate 65, so they will not reverse with the pawl 68, so that the roller 1 63 can only rotate as the fixed frame 2 moves downward. The fixed frame 2 moves downward and drives the inclined frame 715 to move. The inclined frame 715 moves downward and squeezes the sliding sleeve 710 to move toward the lifting plate 82. The inclined frame 715 moves upward and drives the sliding sleeve 710 to reset. The sliding sleeve 710 drives the round pin 79 and the rotating rod 76 to rotate through the driving groove 713. Through the action of the driving groove 713, the reciprocating motion of the sliding sleeve 710 will drive the rotating rod 7 6 rotates in the same direction, and while the rotating rod 76 rotates, the driven wheel 73 is driven to rotate through the driving wheel 75, and the driven wheel 73 drives the second roller 71 to rotate through the gear 72. The second roller 71 transports the slices coming from the direction of the roller 1 63 to the direction of the carrier 83, and in the process of transportation, the slices are separated by taking advantage of the fact that the speed of the second roller 71 is greater than that of the roller 1 63. While the gear 72 rotates, it drives the rack 84 to move upward, and the rack 84 drives the lifting plate 82 to move synchronously. When the lifting plate 82 moves, it drives the carrier 83 to move together. The middle and lower part of the carrier 83 rises from the water pool and adheres to the slice after contacting it. The slice is fished out by continuously moving the carrier 83 upward. After the lifting plate 82 rises to the limit, the carrier 83 is replaced.Then push the lifting plate 82 to move in the direction of the second spring 85, the lifting plate 82 will squeeze the second spring 85 and drive the rack 84 to move synchronously, the rack 84 will release the meshing with the gear 72 after moving, and then push the lifting plate 82 down, after the lifting plate 82 moves down to the maximum stroke, release the lifting plate 82, the lifting plate 82 will be reset under the action of the second spring 85, and drive the rack 84 to mesh with the gear 72 again, and the gear 72 will rotate and drive the lifting plate 82 to rise again to pick up the slices.

[0055] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention rather than to limit it. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solutions of the present invention may be modified or replaced by equivalents without departing from the spirit and scope of the technical solutions of the present invention, which should all be included in the scope of the claims of the present invention.
