Description

Technical Field

[0002] Immunohistochemistry (IHC) is a practical biological experimental technique that uses the principle of specific binding of antigens and antibodies, enzymes, proteins or chemical dyes, to display macromolecular proteins or gene expression in vivo in situ on tissue sections or cell slices. It is widely used in the pathological diagnosis of various diseases such as tumors and inflammation. With the development of digital pathology technology, in order to better perform pathological diagnosis, automated immunohistochemical staining equipment has been put into operation to identify and analyze tissues after the reaction.

DETAILED DESCRIPTION

[0016] The exemplary embodiments of the present disclosure will be described in more detail below with reference to the accompanying drawings. Although the exemplary embodiments of the present disclosure are shown in the accompanying drawings, it should be understood that the present disclosure can be implemented in various forms and should not be limited by the embodiments set forth herein. On the contrary, these embodiments are provided to enable a more thorough understanding of the present disclosure and to fully convey the scope of the present disclosure to those skilled in the art.

[0017] The present application embodiment provides an immunohistochemical reaction system, such as Figure 1 The schematic diagram of the system structure shown in the figure, the system comprises: a tissue sample incubation area 1, a robotic arm 2, a slide holder 3, and a controller 4. Among them, Figure 2As shown, the tissue sample incubation area 1 includes a multi-layer reaction tray 11, and the reaction tray 11 includes a plurality of slide heating areas 111. The slide heating area 111 is provided with a heater 112 aligned with the slide groove 31 on the slide clamp 3. The reaction tray 11 enters and exits the tissue sample incubation area through a conveying device 12 provided on both sides of the tissue sample incubation area; The robot arm is used to clamp the glass slide holder 3 and place it in the glass slide heating area 111 on the reaction tray 11 extending out of the tissue sample incubation area 1 to perform immunohistochemical staining; The slide holder 3 is used to load a plurality of tissue slides; The controller 4 is used to determine the target slide identifier of the target tissue slide, and drive the robotic arm 2 to place the slide clamp 3 carrying the target tissue slide in the target slide heating zone 111 according to the target slide identifier; and control the target heater 112 corresponding to the target slide heating zone 111 to heat according to a preset heating threshold.

[0018] In the embodiment of the present application, in the medical field, immunohistochemical cell tissues, including but not limited to non-diseased tissues or diseased tissues in human organs, are sampled through a glass slide as a tissue sample. At this time, the glass slide groove 31 in the glass slide holder 3 can clamp the glass slide. A glass slide holder 3 includes multiple glass slide grooves 31, and correspondingly, multiple glass slides can be clamped. When the tissue sample needs to be heated and reacted, the glass slide is clamped and moved in the system by the robot arm 2. Among them, the tissue sample incubation area 1 includes a multi-layer reaction tray 11, which is arranged one by one in the tissue sample incubation area 1 according to the structure of each layer. Figure 2 As shown, the reaction tray 11 includes a plurality of glass slide heating zones 111, wherein the glass slide heating zones 111 are provided with heaters 112 aligned with the glass slide grooves 31 on the glass slide holders 3, so that after a glass slide holder 3 is directly placed on the glass slide heating zone 111, the aligned heating zones can directly heat the glass slides in the glass slide grooves 31. The heater 112 is provided on a bridge-shaped table at the bottom of the reaction tray 11, and a cavity is formed with the bridge-shaped table and the bottom for storing dripping medicines. At the same time, a drainage hole 16 is provided at a corner position of the reaction tray 11, such as Figure 2 As shown, the slide heating area 111 in each layer of the reaction tray 11 is arranged in the longitudinal direction, so that the reaction tray 11 can heat multiple slides within the maximum space limit. Figure 2As shown, the reaction tray 11 is also extended out of the tissue sample incubation area 1 through the conveying devices 12 arranged on both sides of the tissue sample incubation area 1, so that the reaction tray 11 can place the slide holder 3 or remove the slide holder 3 after extending out of the tissue sample incubation area 1.

[0019] It should be noted that the reaction system in the embodiment of the present application is triggered by the controller 4. At this time, the controller 4 can be a terminal processor or a server device, and data communication is performed with the mechanical arm 2, the motor 13 and other devices through the communication line. The embodiment of the present application is not specifically limited. Among them, the user can transmit the target carrier identification of the tissue slide on the slide holder 3 to the controller 4 by inputting or taking pictures. The shooting device can also be configured to take pictures of the tissue slide and then produce the corresponding target slide identification for the controller 4 to query and determine. The embodiment of the present application is not specifically limited. Furthermore, the controller 4 can determine the specific position of the slide heating zone 111 according to the target slide identification, that is, determine the target slide heating zone 111 to be placed. At this time, since the tissue sample incubation area 1 includes a multi-layer reaction tray 11, each layer of the reaction tray 11 includes a plurality of slide heating zones 111. When determining the target slide heating zone 111, the idle slide heating zones 111 can be queried one by one. The embodiment of the present application is not specifically limited. After determining the target slide heating zone 111, the controller 4 sends a control instruction to the robot arm 2 to control the continuing arm to move the held target slide clamp 3 to the target slide heating zone 111 for placement, and then control the target heater 112 on the target slide heating zone 111 to heat according to a preset heating threshold. The preset heating threshold includes the heating time and the heating temperature. For example, heating is performed at ±36.5 degrees for 1 day to simulate human body temperature, which is not specifically limited in the embodiments of the present application.

[0020] In addition, in the embodiment of the present application, since the reaction tray 11 is arranged layer by layer, in order to enable the reaction tray 11 to automatically and flexibly extend and retract to prevent the dry slice, the reaction tray 11 enters and exits the tissue sample incubation area 1 through the conveying device 12 arranged on both sides of the tissue sample incubation area 1. Figure 2 As shown, the conveying device 12 includes a shaft wheel and a conveying belt around the two shaft wheels. The motor 13 drives the rear shaft wheel to rotate, and drives the front shaft wheel to rotate through the conveying belt. The front shaft wheel is connected to the reaction tray 11 through transmission, and drives each reaction tray 11 to extend or retract. The time when the motor 13 stops rotating can be controlled by the controller 4 to control the extension and holding time of the reaction tray 11, which is not specifically limited in the embodiment of the present application.

[0021] In another embodiment of the present application, for further definition and explanation, the tissue sample incubation area 1 further includes a motor 13, such as Figure 3 As shown, it is electrically connected to the conveying device 12 and is used to drive the conveying device 12 according to the extension instruction or the entry instruction of the controller 4. The mechanical arm 2 is provided with a clamping claw 5 assembly; the slide holder 3 includes a slide holder body 32 and a slide holder chuck 33, the slide holder chuck 33 is arranged on one side of the slide holder body 32, and the two sides of the slide holder chuck 33 are provided with a card slot 34, and the card slot 34 can be engaged with the clamping claw 5 for clamping; The controller 4 is further used to query the slide heating area 111 in the reaction tray 11 which is in an idle state, and determine the target slide heating area 111 according to the idle state; The controller 4 is further used to determine a conveying path for the robot arm 2 to clamp the target glass slide clamp 3, and after driving the motor 13 to drive the conveying device 12 to extend the reaction tray 11 corresponding to the target glass slide heating zone 111, drive the robot arm 2 according to the conveying path to clamp the glass slide clamp 3 and place it in the target glass slide heating zone 111.

[0022] In order to accurately drive the reaction tray 11 to extend or retract through the controller 4, the tissue sample incubation area 1 further includes a motor 13, which is disposed on the back plate of each layer of the reaction tray 11. Figure 3 As shown, it is electrically connected to the conveying device 12 and is used to drive the conveying device 12 according to the extension instruction or the entry instruction of the controller 4. When the controller 4 determines the target slide heating zone 111 and the corresponding reaction tray 11, it sends a control instruction to the corresponding motor 13 to drive the extension or retraction. The embodiment of the present application does not make specific limitations. At the same time, in order to enable the robot arm 2 to stably hold the slide clamp 3 so that the robot arm 2 can flexibly clamp, a clamping claw 5 component is provided on the robot arm 2. At the same time, as Figure 4 As shown, in order to ensure that the glass slide holder 3 can be stably clamped by the clamping claw 5, the glass slide holder 3 includes a glass slide frame 32 and a glass slide frame clamp 33. The glass slide frame clamp 33 is arranged on one side of the glass slide frame 32. Slots 34 are provided on both sides of the glass slide frame clamp 33 so that the slots 34 and the clamping claw 5 can be engaged and clamped. At the same time, the glass slide frame 32 also includes an elastic clip 35, which is made of elastic metal, one end of which is fixed on the glass slide frame 32, and the other end clamps the glass slide.

[0023] It should be noted that, in order to make the slide heating areas 111 in each layer of the reaction tray 11 be used efficiently, the controller 4 may first query the idle slide heating areas in the reaction tray 11 to determine the target slide heating areas 111 from the idle slide heating areas 111. Specifically, the idle state may be determined based on the heating signal of the heater 112. For screening of all idle slide heating areas 111, the reaction trays 11 may be sorted from top to bottom, and then the idle slide heating areas 111 may be randomly selected from the topmost reaction tray 11. All slide heating areas 111 may also be numbered, and the idle slide heating areas 111 may be sorted in sequence according to the numbers. The embodiment of the present application does not make any specific limitation. After determining the target slide heating zone 111, in order to better control the robot arm 2 to operate in the system environment and improve the moving efficiency, the controller 4 determines the transmission path according to the target reaction tray 11 and the target slide heating zone 111, so that the robot arm 2 can clamp the slide clamp 3 and then move to the target slide heating zone 111 for placement. Among them, the transmission path is a route determined based on the placement position of the target slide heating zone 111 and the clamping position of the target slide clamp 3. The controller 4 determines the placement position of the target slide heating zone 111 and the clamping position of the target slide clamp 3 (for example, the position of the slide clamp 3 that has been repaired in the repair instrument) by loading the moving space coordinates of the robot arm 2, and then optimizes the placement position and the clamping position to obtain the transmission path. The path optimization method is not specifically limited in the embodiment of the present application.

[0024] In the embodiment of the present application, the execution code for generating the transmission path in the controller 4 can be set based on the coordinates provided in the robot arm 2 and the pre-written script code, and the embodiment of the present application does not make specific limitations.

In contrast, the jaw 5 includes a first jaw side 51 and a second jaw side 52. Each jaw side is provided with a plurality of raised surfaces to form a jaw body 53. The raised surfaces form a second angle. At this time, the first angle is complementary to the second angle, so that the slot 34 and the jaw 5 are fit together and clamped by the first angle and the second angle. Figure 5 shown.

[0026] In another embodiment of the present application, in order to further define and illustrate, Figure 6As shown, the system further includes a dripping device 6 for sucking and dripping out medicine; the tissue sample incubation area 1 further includes a medicine refrigeration area 7 and a medicine storage area 88 arranged on the top layer of the reaction tray 11; the medicine refrigeration area 7 is used to provide cold air to the reaction tray 11; the medicine storage area 8 includes a plurality of medicine storage slots 81 for storing medicine bottles; The controller 4 is also used to determine the target medicine and the target dripping amount according to the target slide identification, and drive the dripping device 6 to absorb the medicine from the target medicine bottle and then drip the medicine onto the target tissue slide on the target slide heating area 111.

[0027] In order to efficiently utilize the tissue sample incubation area 1 for immunohistochemical staining, the system further includes a dripping device 6 for sucking and dripping out the reagent. At the same time, in order to efficiently drip, the reagent refrigeration area 7 and the reagent storage area 8 on the top layer of the tissue sample incubation area 1 are Figure 7 As shown, at this time, the medicine refrigeration zone 7 is used to provide cold air to the reaction tray 11, and refrigerant can be used for refrigeration, which is not specifically limited in the embodiment of the present application. At the same time. The medicine storage area 88 includes a plurality of medicine storage slots 81 for storing medicine bottles, and different medicines can be placed in different medicine bottles, which is not specifically limited in the embodiment of the present application. At this time, in order to make the medicine titration accurate and effective, the controller 4 first determines the target medicine and the corresponding target drop amount according to the target slide mark, and then drives the dripping device 6 to absorb the medicine from the target medicine bottle, and then drips the medicine to the target tissue slide on the target slide heating zone 111. Among them, since the slide mark is information for the identity of the standard tissue sample, the controller 4 can pre-store medicines and drop amounts matching different slide marks for query and determination, which is not specifically limited in the embodiment of the present application.

[0028] In another embodiment of the present application, for further definition and explanation, the medicine storage slot 81 includes a first medicine storage slot 811 and a second medicine storage slot 812, wherein the first medicine storage slot 811 is arranged in a honeycomb shape, and the second medicine storage slot 812 is arranged in parallel according to preset rows and preset columns; The controller 4 is further specifically used to determine the suction position of the dripping device 6 according to the target medicine, and determine the dripping position of the dripping device 6 in combination with the target slide heating zone 111; and generate a driving route of the dripping device 6 according to the suction position and the dripping position.

[0029] In order to place more reagents in the tissue sample incubation area 1, the reagent storage tank 81 includes a first reagent storage tank 811 and a second reagent storage tank 812.

In order to enable the dripping device 6 to drip more efficiently and accurately, the controller 4 determines the target medicine and the target dripping amount according to the target slide mark. Specifically, the corresponding dose mapping table can be pre-written in the controller 4, and the correspondence between different slide marks and different medicines and different dripping amounts can be pre-stored, so that the controller 4 can accurately take medicine for storing the medicines and dripping amounts required for the reaction of different slide marks.
