Abstract
Description
Technical Field
[0001] This utility model relates to the field of pathology technology, and in particular to a tissue paraffin block knockout-assisted device. Background Technology
[0002] In the field of pathological research, paraffin embedding is a common method for preparing paraffin blocks of pathological tissue. The specific procedure involves injecting molten paraffin into an embedding mold, placing the pathological tissue inside and pressing it to the bottom, covering the mold, and allowing the paraffin to cool and solidify, thus embedding the pathological tissue into a paraffin block. To obtain the paraffin block for subsequent sectioning and observation, it needs to be removed from the embedding mold.
[0003] Currently, traditional methods for removing paraffin blocks have many drawbacks: On the one hand, operators mostly use manual methods, fixing the embedding mold with their fingers and using a knife to pry open the gap between the embedding box and the mold to loosen the paraffin block and remove it. Manually processing one embedding box takes about 8-12 seconds, and processing 50 samples in batches takes 6-10 minutes. Therefore, this method is not only time-consuming and labor-intensive, but also inefficient and difficult to process in batches. On the other hand, during manual operation, it is difficult to maintain a stable and consistent force applied by the hand, which can easily lead to uneven force on the paraffin block. This may not only damage the paraffin block and affect the accuracy of subsequent section observation, but also increase the risk of the operator being injured by sharp objects, posing a significant safety hazard.

[0024] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.
[0025] Reference Figures 1 to 4As shown, this utility model provides a technical solution: a tissue wax block assisted knockout device, including a base frame 1, a support frame 2 fixedly connected to the surface of the base frame 1, placement plates 3 fixedly connected to both sides of the support frame 2, a plurality of placement slots 4 evenly opened on the surface of the placement plates 3, a plurality of fixed rotating rods 5 fixedly connected to the surface of the support frame 2, a movable arm 6 rotatably connected to the top of each of the fixed rotating rods 5, a striking seat 7 rotatably connected to one end of the movable arm 6, a striking ball 8 fixedly connected to the lower end of the striking seat 7, the striking ball 8 being located above the placement slots 4, and a stable support structure is formed by setting the base frame 1 and the support frame 2. The structure utilizes multiple placement slots 4 on the placement plate 3 to achieve batch positioning of inverted embedding frames containing wax blocks, ensuring that the embedding frames and wax blocks are not easily displaced during processing. At the same time, through the coordinated operation of the fixed rotating rod 5, the movable arm 6, the striking seat 7, and the striking ball 8, the striking ball 8 can accurately act on the inverted embedding frames in the placement slots 4. The striking force on the embedding frames is transmitted to the wax blocks, providing a stable force point for the separation and removal of the wax blocks from the embedding frames. This effectively improves the convenience and stability of the process of removing tissue wax blocks from the embedding frames, which is conducive to improving processing efficiency and reducing the labor intensity of manual operation.
[0026] Reference Figure 3 and Figure 4 As shown in this embodiment: the end of the movable arm 6 away from the striking seat 7 is rotatably connected to a lower pressure plate 9. A return spring 10 is provided on the lower surface of the lower pressure plate 9. The lower end of the return spring 10 is fixedly connected to the surface of the support frame 2. The number of lower pressure plates 9 is set to multiple sets, and a connecting plate 11 is fixedly connected between the multiple sets of lower pressure plates 9. A positioning rod 12 is slidably connected to the surface of the connecting plate 11. The lower end of the positioning rod 12 is fixedly connected to the surface of the support frame 2. Two fixing plates 14 are fixedly connected to the surface of the support frame 2. A rotating shaft 15 is rotatably connected between the two fixing plates 14. A triangular cam 16 is fixedly connected to the surface of the rotating shaft 15. The triangular cam 16 is located above the lower pressure plate 9. A servo motor 17 is provided at one end of the rotating shaft 15. The servo motor 17 is mounted on the fixed... The surface of plate 14 is rotatably connected to the lower pressure plate 9 via the end of the movable arm 6 away from the striking seat 7. This, along with the return spring 10 on the lower surface of the lower pressure plate 9 and its fixation to the support frame 2, enables the lower pressure plate 9 to automatically reset after being pressed. The connecting plate 11 and positioning rod 12 between multiple sets of lower pressure plates 9 slide together, ensuring the guiding stability of the lower pressure plate 9's movement. The arrangement of the fixed plate 14, rotating shaft 15, triangular cam 16, and servo motor 17 allows the triangular cam 16 to periodically press down the lower pressure plate 9, which in turn drives the striking ball 8 via the movable arm 6 to regularly strike the inverted embedding frame within the placement slot 4. This effectively improves the automation and consistency of the striking action, ensuring the efficiency and reliability of separating and removing the wax block from the embedding frame, and reducing manual intervention and labor intensity.
[0027] Reference Figure 1, Figure 2 and Figure 3 As shown, specifically, a fixing knob 13 is provided at the connection between the striking base 7 and the movable arm 6. The surface of the fixing knob 13 is provided with anti-slip texture. A sliding groove 18 is provided on the surface of the base frame 1. A slide plate 19 is slidably connected to the inner wall of the sliding groove 18. A receiving box 20 is fixedly connected to one side of the slide plate 19. The receiving box 20 is located below the placement slot 4. By providing a fixing knob 13 at the connection between the striking base 7 and the movable arm 6, the angle of the striking base 7 relative to the movable arm 6 can be adjusted and fixed. The anti-slip texture facilitates the application of force by the operator during manual adjustment, improving the convenience and stability of the adjustment operation. The sliding groove 18 on the surface of the base frame is slidably connected to the slide plate 19. Combined with the receiving box 20 fixed on one side of the slide plate 19 and located below the placement slot 4, it can effectively receive the wax blocks that fall during the knocking process. The inner wall of the receiving box 20 is lined with a sponge pad to prevent the wax blocks from breaking. At the same time, the sliding design of the slide plate 19 facilitates the removal, placement and cleaning of the receiving box 20, further improving the practicality and convenience of the device.
[0028] Working principle: First, the base frame 1 and the support frame 2 form a stable support structure. The operator inverts the embedding frame containing the wax block and places it into the placement slot 4 of the placement plate 3. The placement slot 4 limits the embedding frame, ensuring that it is not easily displaced during the knocking process, thus achieving stable placement of a batch of embedding frames to be processed. After the device is started, the servo motor 17 drives the rotating shaft 15 to rotate, which drives the triangular cam 16 fixed on the surface of the rotating shaft 15 to rotate synchronously. When the protruding part of the triangular cam 16 rotates to above the lower pressure plate 9, it will exert downward pressure on the lower pressure plate 9. After the lower pressure plate 9 is pressed, the force is transmitted through the movable arm 6, causing the movable arm 6 to rotate around the fixed rotating rod 5, which in turn drives the striking seat 7 and the striking ball 8 at the lower end to move downward, accurately striking the inverted embedding frame in the placement slot 4. The striking force is transmitted to the wax block, causing the wax block to separate from the embedding frame. When the protruding part of the triangular cam 16 leaves the lower pressure plate... After step 9, the lower pressure plate 9 returns to its original position under the elastic force of the return spring 10, simultaneously driving the movable arm 6, the striking seat 7, and the striking ball 8 back to their initial positions. This cycle repeats, enabling the striking ball 8 to automatically and regularly strike the embedding frame. During this process, the connecting plate 11 and the positioning rod 12 between the multiple sets of lower pressure plates 9 slide together to ensure the guiding stability of the movement of the lower pressure plate 9 and the movable arm 6, ensuring the consistency and reliability of the striking action. In addition, the operator can adjust the angle of the striking seat 7 relative to the movable arm 6 by loosening the fixing knob 13 at the connection between the striking seat 7 and the movable arm 6 to adapt to the striking requirements of embedding frames of different sizes. After adjustment, tightening the fixing knob 13 will achieve positioning. The anti-slip texture on the surface of the fixing knob 13 improves the convenience and stability of the adjustment operation. The wax blocks that fall during the striking process fall into the receiving box 20 located below the placement slot 4, which can be easily removed for retrieval.
