DETAILED DESCRIPTION

[0015] In the description of the present invention, it should be noted that the terms "center", "up", "down", "left", "right", "vertical", "horizontal", "inside", "outside", etc., indicating directions or positional relationships, are based on the directions or positional relationships shown in the accompanying drawings. They are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific direction, be constructed and operated in a specific direction. Therefore, they cannot be understood as limitations on the present invention.

[0016] In the description of this utility model, it should be noted that, unless otherwise specified or limited, the terms "mounted," "connected," and "connected" should be understood in a broad sense. For example, they may refer to fixed connections, detachable connections, or integral connections. Those skilled in the art will understand the specific meanings of these terms in this utility model based on the specific circumstances.

[0017] Below with reference to the embodiment and the attached Figures 1 to 4 , the technical solution of the utility model is further elaborated.

[0018] Example 1

[0019] A device for autologous cell smear recovery includes: a workbench 1 and a scraper mechanism 2, wherein the workbench 1 is provided with slide grooves 11 on both sides and a glass slide placement groove 12 on the upper end, a glass slide carrier 3 is slidably arranged in the glass slide placement groove 12, the scraper mechanism 2 includes a sliding bracket 21 slidably arranged on the slide groove 11, a mounting bracket 22 fixedly arranged on the sliding bracket 21, and a scraper frame 23 rotatably arranged at the end of the mounting bracket 22, a scraper 24 is slidably arranged on the scraper frame 23, and a collection mechanism 4 is provided at the end of the workbench 1.

[0020] like Figures 1 to 4 As shown, in actual operation, the glass slide to be processed is first placed in the glass slide carrier 3, and then the glass slide carrier 3 is slid into the glass slide placement groove 12 to fix the glass slide. Then, the operator moves the scraper mechanism 2 to align the scraper 24 with the cell smear on the glass slide, and by rotating the scraper holder 23, the scraper 24 moves along the surface of the glass slide to scrape the cell smear. The scraped cell sample then falls into the collection mechanism 4 for subsequent processing and analysis.

[0021] The utility model collects scrapers by pushing and pulling the scraper mechanism 2, and can more fully recycle and reuse the visible components of the cell smear under the premise of avoiding occupational exposure to make cell wax blocks; while avoiding the patient's secondary puncture, immunohistochemistry and molecular pathology tests are carried out through the cell wax blocks to achieve a clear pathological diagnosis.

[0022] As a further preferred embodiment, an arc-shaped slot 221 and a locking bolt 222 threadedly connected to the outer side of the arc-shaped slot 221 are fixedly provided on the side wall at the end of the mounting frame 22. The scraper frame 23 includes a rotating shaft 231 rotatably set at the end of the mounting frame 22 and a mounting frame 232 and an arc-shaped locking arm 233 set on the rotating shaft 231. The upper end of the arc-shaped locking arm 233 is rotatably set in the arc-shaped slot 221.

[0023] Specifically, by rotating the locking bolt 222 , the position of the arc-shaped locking arm 233 in the arc-shaped slot 221 can be adjusted, thereby fine-tuning the contact pressure and angle between the scraper 24 and the glass slide.

[0024] As a further preferred embodiment, an elastic limiting assembly 31 is provided inside the glass slide carrier 3 , and the elastic limiting assembly 31 includes a limiting plate 311 slidably provided inside the glass slide carrier 3 and a spring 312 provided at the side end of the limiting plate 311 .

[0025] Specifically, during the process of installing the glass slide, the elastic limiting component 31 provides stable support and positioning for the glass slide carrier 3 when sliding, ensuring that the glass slide will not shift or fall off during the placement and movement process; and the spring 312 provides elastic force for the limiting plate 311. When the glass slide carrier 3 moves in the sliding groove 11, the spring 312 can buffer the force generated by friction or impact, protecting the glass slide from damage.

[0026] As a further preferred embodiment, a cleaning tube 5 is fixedly provided on the sliding bracket 21. A suitable cleaning agent, such as 95% alcohol, can be injected into the cleaning tube 5 according to the actual working conditions. When the operation is completed, the workbench is disinfected by the cleaning agent, meeting the hospital's requirements for avoiding cross infection.

[0027] As a further preferred embodiment, the collection mechanism 4 includes a first collection tube 41 obliquely arranged at the side end of the workbench 1 and a second collection tube 42 threadedly connected to the end of the first collection tube 41. After the collection is completed, the scraped cell tissue flows into the second collection tube 42 under the action of gravity, and then the second collection tube 42 is turned away from the first collection tube 41 for storage. The structure is simple and the operation is convenient.

[0028] The above describes in detail the preferred embodiments of the present invention. It should be understood that those skilled in the art can make numerous modifications and variations based on the concepts of the present invention without inventive effort. Therefore, any technical solutions that can be derived by those skilled in the art based on the concepts of the present invention through logical analysis, reasoning, or limited experimentation based on the existing technology should be within the scope of protection defined by the claims.
