[0002] Pathological tissue refers to tissue samples taken from an organism that have abnormal changes in morphology, structure or function. These changes may be caused by disease. Pathological tissue is usually blocky and has a complex internal structure. By sectioning, the tissue can be cut into very thin slices, so that the cell morphology, tissue structure and the relationship between cells of the tissue can be observed more clearly under a microscope, which helps pathologists accurately determine whether the tissue has lesions and the specific characteristics of the lesions, thereby helping to diagnose the disease.

[0003] In the prior art, when making a pathological diagnosis of an organism, it is often necessary to take a certain size of diseased tissue, soak the pathological tissue in paraffin wax for solidification and staining, and then cut it into thin slices suitable for microscopic observation by a pathological slicer.

[0023] In this embodiment, when in use, the slicer body 2, the forward and reverse motor 701 and the controller 3 are electrically connected. The slicer body 2 is an existing mature technology, mainly including a fixing device, a knife holder and a knife feed device. The fixing device and the knife holder are used to fix the pathological tissue. The knife feed device controls the up and down movement of the fixing device and the knife holder through a hand wheel. The initial state of the protective cover 704 is as follows Figure 5 and Figure 7As shown, the shield is placed above the blade of the slicing knife 6, and the blade of the slicing knife 6 is protected by the shield 704, which is arranged in an arc shape.

[0024] Embodiment 2: Figure 4-Figure 8As shown, the cleaning assembly 8 includes a movable plate 801, and four cleaning rods 802 are movably embedded in the movable plate 801. The bottom ends of the four cleaning rods 802 are fixedly installed with limit plates 803, and the bottoms of the four limit plates 803 are fixedly installed with threaded columns 804. The bottom of the movable plate 801 is fixedly connected with two springs 805, and one end of the two springs 805 is fixedly connected with a mounting plate 806. A cleaning plate 808 is arranged at the bottom of the mounting plate 806, and a cleaning sponge 809 is fixedly connected to the cleaning plate 808. Four movable holes 807 are opened on the top of the mounting plate 806, and four threaded grooves 810 are opened on the top of the cleaning plate 808. The outer surfaces of the four threaded columns 804 are movably embedded in the four movable holes 807, and the top of the cleaning plate 808 is opened. Inside the hole 807, the bottom ends of the four threaded columns 804 are respectively threadedly embedded in the four threaded grooves 810, the top ends of the four cleaning rods 802 are movably sleeved with moving blocks 811, the outer surface of the protective cover 704 is provided with a movable hole 709, the inside of the movable hole 709 is fixedly installed with a sliding rod 710, both sides of the inside of the movable hole 709 are provided with limiting grooves 711, the outer surface of the movable plate 801 is movably embedded in the two limiting grooves 711, one end of the sliding rod 710 movably penetrates to the outer surface of the movable plate 801, the outer surfaces of the four cleaning rods 802 are all movably embedded in the movable hole 709, and the mounting plate 806, the cleaning plate 808 and the cleaning sponge 809 are all located inside the protective cover 704.

[0025] In this embodiment, when in use, Figure 5As shown, the cleaning assembly 8 is located at one side of the protective cover 704. When it is necessary to fix the pathological tissue, the moving block 811 is first pushed, and the moving plate 801, the mounting plate 806 and the cleaning plate 808 are driven to move to the top of the slicer 6 through the cleaning rod 802, and then the moving block 811 is pressed downward, and the cleaning rod 802 is pushed downward. Under the limiting action of the limiting plate 803, the mounting plate 806 and the cleaning plate 808 are pushed downward together. At the same time, the spring 805 is pulled by the mounting plate 806 and unfolds downward. When the cleaning plate 808 moves downward , driving the cleaning sponge 809 to move downward, so that the cleaning sponge 809 is sleeved on the blade of the slicer 6, at this time, the two sides of the blade of the slicer 6 are in contact with the two sides inside the cleaning sponge 809, and then maintaining the downward pressing force, pushing the moving block 811 to move, driving the moving plate 801 to slide on the outer surface of the slide bar 710, and then driving the cleaning plate 808 and the cleaning sponge 809 to move, thereby wiping and cleaning the blade of the slicer 6, reducing the influence of dust impurities on the blade of the slicer 6 on the pathological tissue, thereby achieving the effect of cleaning dust. After the cleaning of the slicer 6 is completed, the pressing of the moving block 811 is released, the cleaning rod 802, the mounting plate 806 and the cleaning plate 808 lose the pressing force, the spring 805 loses the pulling force, and starts to rebound. Under the elastic force of the spring 805, the mounting plate 806 and the cleaning plate 808 are pulled upward to reset, thereby separating the cleaning sponge 809 from the slicer 6, and not affecting the normal operation of the subsequent protection component 7. Then, the protection component 7 is started, and the protection cover 704 is rotated into the storage slot 708, and subsequent pathological tissue sectioning work can be carried out.

[0026] The effect and working principle of the whole mechanism are as follows: the slicer body 2 is an existing mature technology, mainly including a fixing device, a knife holder and a knife feed device, the fixing device and the knife holder are used to fix the pathological tissue, and the knife feed device controls the up and down movement of the fixing device and the knife holder through a hand wheel. Figure 5 and Figure 7 As shown, the shield is placed above the blade of the slicing knife 6, and the blade of the slicing knife 6 is protected by the shield 704, which is arranged in an arc shape. Figure 6As shown, when the staff puts the pathological tissue into the knife holder of the slicer body 2 and fixes the pathological tissue by the fixing device, under the protection of the protective cover 704, the staff can avoid accidentally touching the blade of the slicer knife 6 and causing hand injuries, thereby improving safety. After the pathological tissue is fixed, the blade of the slicer 6 is cleaned through the cleaning component 8 to reduce the influence of dust and impurities on the pathological tissue slices, and then the forward and reverse motor 701 is started through the operation button on the controller 3, and the first rotating bar 702 is driven to rotate backward through the output end of the forward and reverse motor 701, and the first fixing rod 703 is driven to rotate backward, and the protective cover 704 and the cleaning component 8 are further driven to rotate backward, so that the protective cover 704 rotates from the top of the slicer 6 to the storage groove 708, and at the same time, the second fixing rod 705 and the second rotating bar 706 are driven to rotate, and the rotating rod 707 is rotated in the rotating hole on the outer surface of the adjustment seat 5, without affecting the forward and reverse rotation of the protective cover 704. When the forward and reverse motor 701 is automatically turned off, the protective cover 704 just rotates from the top of the slicer 6 to the storage groove 708, and does not affect the subsequent up and down movement of the fixing device and the pathological tissue in the slicer body 2. After the protective cover 704 is stored, the knife feed device in the slicer body 2 controls the fixing device and the pathological tissue to move up and down, so that the pathological tissue contacts the slicer 6 for slicing. When a new pathological tissue needs to be replaced, the forward and reverse motor 701 is started again, and the output end of the forward and reverse motor 701 rotates in the opposite direction, driving the first rotating bar 702 and the first fixing rod 703 to rotate forward with the output end of the forward and reverse motor 701 as the center of the circle, thereby driving the protective cover 704 to rotate to the top of the slicer 6 again, thereby protecting the blade of the slicer 6, preventing accidental injury when replacing other pathological tissues, and not affecting the normal slicing work. When it is necessary to fix the pathological tissue, the moving block 811 is first pushed, and the moving plate 801, the mounting plate 806 and the cleaning plate 808 are moved to the top of the slicer 6 through the cleaning rod 802, and then the moving block 811 is pressed downward, and the cleaning rod 802 is pushed downward. Under the limiting action of the limiting plate 803, the mounting plate 806 and the cleaning plate 808 are pushed downward together. At the same time, the spring 805 is pulled downward by the mounting plate 806, and the cleaning plate 808 moves downward, driving the cleaning sponge 809 Move downward, so that the cleaning sponge 809 is sleeved on the blade of the slicer 6, at this time, the two sides of the blade of the slicer 6 are in contact with the two sides inside the cleaning sponge 809, and then keep the force of pressing downward, and push the moving block 811 to move, drive the moving plate 801 to slide on the outer surface of the slide bar 710, and then drive the cleaning plate 808 and the cleaning sponge 809 to move, so as to wipe and clean the blade of the slicer 6, reduce the influence of dust impurities on the blade of the slicer 6 on the pathological tissue, so as to achieve the effect of cleaning dust. After completing the cleaning of the slicer 6, start the protection component 7, rotate the protection cover 704 to the storage slot 708, and then carry out the subsequent pathological tissue slicing work.

[0027] Among them, the slicer body 2, the forward and reverse motor 701 and the controller 3 are all existing technologies, and their components and operating principles are all public technologies, so no excessive explanation will be given here.
