[0002] Hematoxylin and eosin (HE) staining is a commonly used staining method in histological studies to stain tissue sections for observation and analysis of tissue structure and cell morphology. HE staining involves placing the tissue section specimen in a staining chamber and then performing a series of processes including heating, dewaxing, staining, washing, and mounting to ensure uniform and accurate staining. HE staining machines are easy to operate, produce high-resolution staining results, and shorten staining time. Widely used in medical, biological, and pathological diagnostics, it can accommodate tissue sections of different sizes and shapes, reducing manual labor and providing more accurate histological information.

[0012] This invention discloses a slide-stepping transmission device for a pathological tissue individual staining system. Currently, most pathological tissue staining machines on the market use fixed slides. When adding reagents, a sample loading robot moves above the slide to add the sample. Since tissue staining involves multiple steps requiring different reagents to be added at different times, the limited space for the reagent loading robot makes it difficult to install multiple robots. The fixed slide mode also struggles to meet high-throughput requirements. This patent's stepping displacement device allows the reagent loading module to be fixed while the slide moves stepwise. When the slide reaches a predetermined position, the reagent loading module operates. After loading, the slide continues to move stepwise to the next step until all steps are completed. A slide flipping mechanism grips and flips the transported slide, and then a lifting mechanism is provided. The device drives the entire slide lateral displacement mechanism to transport the slides placed on the staining frame module once. Then, it drives the slide lateral displacement mechanism to move down and reset, so as to transport the subsequently reintroduced slides. This completes the step-by-step transmission of the introduced slides. When the slide moves to the end, the corresponding front-pushing mechanism on one side transfers the slide to the other side for back transport. This repeated operation can complete the stable transmission of the slides. The device has a fixed displacement distance and a programmed step time, which ensures consistent staining time and significantly improves staining consistency. At the same time, the staining frame slides adopt a "bow"-shaped step displacement structure, which greatly reduces the size of the instrument and reduces manufacturing costs. This patented device enables the instrument to realize loading and unloading functions more easily, achieving truly fully automated production line operation. Attached Figure Description

The right shift assembly and the left shift assembly mounted on the slider also form a "split" movement.

[0031] In this embodiment, a slide stepping transmission device for a pathological tissue individual staining system is used. Because most pathological tissue staining machines on the market have fixed slides, requiring a sample loading robot to move above the slide to add reagents, and because tissue staining involves multiple steps requiring different reagents at different times, the limited space for the reagent loading robot makes it difficult to install multiple robots. The fixed slide mode also struggles to meet high-throughput requirements. This patent's stepping displacement device fixes the reagent loading module while the slide moves stepwise. When the slide reaches a predetermined position, the reagent loading module operates, and after loading, the slide continues to step forward to the next step until all steps are completed. The slide flipping mechanism 1, which holds the transported slide, is then used by the robot to grip it. The slide is clamped and flipped, and then the entire slide lateral displacement mechanism 6 is driven by the lifting mechanism 5 to transport the slide placed on the staining frame module 2. After that, the slide lateral displacement mechanism 6 is driven to move down and reset, so as to transport the subsequently reintroduced slides. This completes the step-by-step transmission of the introduced slides. When the slide moves to the end, the front deflector mechanism on the corresponding side transfers the slide to the other side for back transport. This repeated operation can complete the stable transmission of the slides. The displacement distance of this device is fixed and the step time is programmed, so the staining time is consistent and the staining consistency is significantly improved. At the same time, the staining frame slide adopts a "bow"-shaped step displacement structure, which greatly reduces the design size of the instrument and reduces manufacturing costs. This patented device can make the instrument realize the loading and unloading function more simply and realize a truly fully automated production line operation.
