Description

Technical Field

[0001] This utility model relates to the field of pathological tissue processing technology, specifically to an embedding cassette fixation device. Background Technology

[0002] In experimental fields such as biomedicine and pathology, embedding cassette fixation devices are important equipment in the process of tissue sample processing. Existing embedding cassette fixation devices usually adopt mechanical clamping or slot limiting structures, and fix the embedding cassette in a preset position by means of bolt tightening, spring buckle, etc., to ensure that the tissue sample remains stable during embedding, sectioning and other operations, and avoid sample damage or reduction of processing accuracy due to shaking or displacement. This device can achieve the initial positioning and fixation of the embedding cassette, and provide basic support for subsequent experimental operations.

[0003] The existing mechanical clamping structure of the embedding cassette fixing device is prone to bolt loosening and spring clip elasticity weakening after frequent use, resulting in the embedding cassette not being firmly fixed and affecting the stability of sample processing. In addition, the existing slot limiting structure has relatively fixed dimensions, making it difficult to adapt to embedding cassettes of different specifications, resulting in poor versatility. Utility Model Content

[0004] The purpose of this utility model is to provide an embedding cassette fixing device to solve the problems mentioned in the background art. In the mechanical clamping structure of the existing embedding cassette fixing device, after frequent use, the bolts are prone to loosening and the elasticity of the spring clips weakens, resulting in the embedding cassette not being firmly fixed, affecting the stability of sample processing. In addition, the existing slot limiting structure has relatively fixed dimensions, making it difficult to adapt to embedding cassettes of different specifications and resulting in poor versatility.

[0005] To achieve the above objectives, the present invention provides the following technical solution: an embedding box fixing device, including a limiting base, which is the basic bearing structure of the device and provides a stable installation and support benchmark for the entire fixing device. The upper end of the limiting base is provided with an embedding box placement groove, and the embedding box placement groove provides installation space for the embedding box.

[0006] One limiting pin is installed through each end of the limiting base, and one side of the limiting pin abuts against the side wall of the sliding frame. Two sliding frames are provided and slide on the side of the limiting base. Protective pads and limiting push plates are symmetrically placed inside the embedding box placement slot.

[0007] The limiting push plate is engaged with an auxiliary wedge, and the limiting push plate is connected to the output ends of two telescopic columns. The top of the sliding frame is provided with auxiliary sliding columns at equal intervals, and the auxiliary sliding columns are slidably connected to the connecting cover. The connecting cover and the two sliding frames form a U-shaped structure, and the connecting cover has holes.

[0008] By adopting the above technical solution, a three-dimensional fixed structure is constructed through the coordinated use of multiple components such as the limiting base, the embedding box placement groove, the limiting push plate, and the connecting cover.

[0009] Preferably, the limiting base has two holes adapted to the telescopic column, and the holes of the limiting base are connected to the embedding box placement groove.

[0010] By adopting the above technical solution, the inner hole of the limiting base is adapted to the telescopic column and connected to the embedding box placement slot, so that the driving force of the telescopic column can be directly and stably transmitted to the limiting push plate, ensuring that the lateral clamping force is accurate and controllable.

[0011] Preferably, the limiting base has a sliding groove on its side that is slidably connected to the sliding frame, and the top opening of the sliding frame is flush with the side wall of the embedding box placement slot opening.

[0012] Using the above technical solution, the sliding groove on the side of the limiting base cooperates with the sliding frame, and the top opening of the sliding frame is flush with the opening of the embedding box placement slot, so that the sliding frame can slide flexibly and be accurately positioned.

[0013] Preferably, the surface of the limiting push plate is provided with a groove, and the groove of the limiting push plate is engaged with one side of the auxiliary wedge, and the auxiliary wedge is set in an inclined shape.

[0014] Using the above technical solution, the groove of the limiting push plate engages with the inclined auxiliary wedge. When the embedding box is clamped laterally, the inclined wedge can not only apply a stable squeezing force, but also guide the embedding box to finely adjust its position, so as to achieve precise fixation.

[0015] Preferably, the auxiliary slide column is slidably connected to the connecting cover, and the auxiliary slide column has a hole, and a spring for connecting the connecting cover is provided in the hole of the auxiliary slide column.

[0016] By adopting the above technical solution, the spring inside the auxiliary slide column cooperates with the connecting cover, and the elastic force of the spring provides an adjustable top clamping force for the connecting cover.

[0017] Preferably, the connecting cover is arranged parallel to the limiting base, and the connecting cover is provided with a sliding groove that is compatible with the thickened silicone pad.

[0018] Using the above technical solution, the connecting cover is arranged parallel to the upper part of the limiting base and has a sliding groove that is compatible with the thickened silicone pad, so that the thickened silicone pad can be flexibly slid and adjusted in position.

[0019] Preferably, a thickened silicone pad is slidably connected inside the connecting cover, and an opening is provided inside the thickened silicone pad, which is aligned with the opening of the connecting cover.

[0020] The above technical solution, with the openings of the connecting cap and the thickened silicone pad aligned, ensures stable fixation of the top of the embedding box without obstructing the embedding box operation area.

[0021] Compared with the prior art, the beneficial effects of this utility model are: the embedding box fixing device:

[0022] 1. The limiting base serves as the basic load-bearing structure. The embedding box placement slot at its upper end is the initial placement area for the embedding box. During use, the embedding box is placed into the slot. The protective pad, with its own material elasticity and anti-slip properties, initially buffers and restricts the sliding of the bottom of the embedding box, completing the basic positioning. At the same time, the limiting pins at both ends of the limiting base cooperate with the sliding frame on the side. The limiting pins abut against the side wall of the sliding frame to limit the initial position of the sliding frame, ensuring that it is aligned with the opening of the embedding box placement slot before sliding, preparing for subsequent enclosure and fixation.

[0023] 2. After the embedding cassette is initially positioned, the limiting push plate and the telescopic column work together: the output end of the telescopic column pushes the limiting push plate to move towards the embedding cassette. The inclined auxiliary wedge on the surface of the limiting push plate uses a wedge structure to apply lateral pressure to the embedding cassette when it contacts the side of the embedding cassette. On the other hand, it guides the embedding cassette to fine-tune its position so that it is precisely matched with the embedding cassette placement slot and other fixing components. At the same time, the sliding frame on the side of the limiting base can slide along the sliding groove. Its top auxiliary sliding column is slidably connected to the connecting pressure cap. During the movement of the sliding frame, the auxiliary sliding column cooperates with the connecting pressure cap through the internal spring to provide pre-tightening force for the connecting pressure cap, further assisting in clamping the embedding cassette from the side, and completing the lateral fixation with the limiting push plate.

[0024] 3. Once the lateral clamping is in place, the U-shaped structure formed by the connecting cap and the two sliding frames surrounds the embedding cassette from above. The thickened silicone pad, which slides inside the connecting cap, adheres to the top of the embedding cassette thanks to the elasticity of the silicone and its anti-slip properties. The thickened silicone pad is aligned with the opening of the connecting cap to avoid obstructing the embedding cassette's operating area. At the same time, the spring inside the auxiliary slide column continuously provides elastic force, which, together with the connecting cap's own structure, applies a stable clamping force to the top of the embedding cassette, achieving a firm fixation of the embedding cassette in three-dimensional space and providing a stable foundation for subsequent embedding operations.

[0032] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0033] Please see Figures 1-6 This utility model provides a technical solution: an embedding box fixing device, including a limiting base 1, a limiting pin 2, an embedding box placement groove 3, a protective pad 4, a limiting push plate 5, an auxiliary wedge 6, a telescopic column 7, a sliding frame 8, an auxiliary sliding column 9, a connecting pressure cover 10, and a thickened silicone pad 11.

[0034] Among them, the limiting base 1 is the basic bearing structure of the device, providing a stable installation and support benchmark for the entire fixed device. The upper end of the limiting base 1 is provided with an embedding box placement groove 3, and the embedding box placement groove 3 provides installation space for the embedding box.

[0035] One limiting pin 2 is installed through each end of the limiting base 1, and one side of the limiting pin 2 abuts against the side wall of the sliding frame 8. Two sliding frames 8 are provided and slide on the side of the limiting base 1. A protective pad 4 and a limiting push plate 5 are symmetrically placed inside the embedding box placement slot 3. The limiting base 1 has two holes adapted to the telescopic column 7, and the holes of the limiting base 1 are connected to the embedding box placement slot 3. The side of the limiting base 1 has a sliding groove that is slidably connected to the sliding frame 8, and the top opening of the sliding frame 8 is flush with the side wall of the opening of the embedding box placement slot 3.

[0036] Referring to the attached diagrams in the instruction manual Figures 1-6As shown, place the protective pad 4 at the bottom of the embedding box placement slot 3, ensuring a snug fit without misalignment; engage the auxiliary wedge 6 into the groove of the limiting push plate 5, check the engagement firmness, insert the spring into the hole of the auxiliary slide post 9, then connect the auxiliary slide post 9 to the connecting cover 10, insert the two telescopic posts 7 into the corresponding holes in the limiting base 1, ensuring that the output end of the telescopic post 7 is precisely aligned with the limiting push plate 5, embed the two sliding brackets 8 into the sliding grooves on the side of the limiting base 1, and adjust... Position the slide frame 8 so that the top opening is flush with the side wall of the embedding box placement slot 3; install the limiting pin 2 through to both ends of the limiting base 1 so that one side of the limiting pin 2 abuts against the side wall of the slide frame 8, thereby limiting the initial position of the slide frame 8; slide the thickened silicone pad 11 into the groove in the connecting cover 10; adjust the position of the silicone pad so that the opening of the thickened silicone pad 11 is aligned with the opening of the connecting cover 10; and then connect the connecting cover 10 to the auxiliary sliding post 9 at the top of the slide frame 8.

[0037] The limiting push plate 5 is engaged with an auxiliary wedge 6, and the limiting push plate 5 is connected to the output ends of two telescopic columns 7. The limiting push plate 5 has a groove, and the groove of the limiting push plate 5 is engaged with one side of the auxiliary wedge 6. The auxiliary wedge 6 is inclined. The top of the sliding frame 8 is equidistantly provided with auxiliary sliding columns 9, and the auxiliary sliding columns 9 are slidably connected with the connecting cover 10. The connecting cover 10 and the two sliding frames 8 form a U-shaped structure. The connecting cover 10 has a hole. The auxiliary sliding column 9 is slidably connected with the connecting cover 10. The auxiliary sliding column 9 has a hole, and the hole of the auxiliary sliding column 9 is provided with a spring connecting the connecting cover 10. The connecting cover 10 is parallel to the limiting base 1, and the connecting cover 10 has a groove that matches the thickened silicone pad 11. The thickened silicone pad 11 is slidably connected in the connecting cover 10. The thickened silicone pad 11 has an opening, and the opening is aligned with the opening of the connecting cover 10.

[0038] Referring to the attached diagrams in the instruction manual Figures 1-6 As shown, the operator holds the embedding box, aligns it with the embedding box placement slot 3 at the upper end of the limiting base 1, and slowly places it into the slot. The protective pad 4 at the bottom of the slot, due to its own elastic material, adheres to the side wall of the embedding box, and uses its anti-slip properties to increase friction, initially buffering the impact force when the embedding box is placed in, limiting its bottom sliding, completing the basic positioning, and ensuring that the embedding box is stable in the slot.

[0039] After the embedding cassette is positioned, the telescopic column 7 is activated and opened / closed via the control device. The output end of the telescopic column 7 extends, pushing the limiting push plate 5 towards the embedding cassette. The inclined auxiliary wedge 6 on the surface of the limiting push plate 5 moves with the push plate. When it contacts the side of the embedding cassette, the wedge structure generates a bidirectional effect. Using the inclined guide, the embedding cassette is guided to finely adjust its position in the placement slot 3. At the same time, the limiting pins 2 at both ends of the limiting base 1 continuously abut against the side wall of the sliding frame 8, limiting the sliding range of the sliding frame 8. The operator can manually push the sliding frame 8 to slide along the side slide groove. The auxiliary sliding column 9 at the top of the sliding frame 8 moves with the sliding frame 8. Its internal spring is compressed due to the limiting of the connecting cover 10, generating elastic force to provide pre-tightening pressure above the embedding cassette. The connecting cover 10 is subjected to the pre-tightening force and moves towards the embedding cassette, further assisting in clamping the embedding cassette from the side. Together with the limiting push plate 5, it completes the lateral fixation, making the embedding cassette unable to move in the horizontal direction.

[0040] When the lateral clamping is in place, the U-shaped structure formed by the connecting cap 10 and the two sliding frames 8 surrounds the embedding cassette from above. The thickened silicone pad 11 inside the connecting cap 10 adheres to the top of the embedding cassette due to the elasticity of the silicone, increasing friction with the cassette due to its anti-slip properties. The opening of the silicone pad is aligned with the opening of the connecting cap 10 to avoid obstructing the embedding cassette's operating area. The spring inside the auxiliary slide column 9 continuously provides elastic force, which, together with the structure of the connecting cap 10 itself, applies a stable clamping force to the top of the embedding cassette. After the embedding operation is completed, the telescopic column 7 is operated in the opposite direction, causing its output end to retract, which moves the limit push plate 5 away from the embedding cassette. The auxiliary wedge block 6 releases the lateral pressure on the embedding cassette. The sliding frame 8 is manually or pulled back through the linkage mechanism to reset, the auxiliary slide column 9 spring rebounds, and the connecting cap 10 moves upward to release the top clamping. Finally, the embedding cassette is removed, and the surfaces of the protective pad 4, connecting cap 10, and other components are cleaned to remove any residual paraffin or impurities, preparing for the next use.

[0041] Working principle: When using this embedding cassette fixing device, the embedding cassette is placed in the slot. The protective pad 4, with its own material elasticity and anti-slip properties, initially buffers and restricts the sliding of the bottom of the embedding cassette, completing the basic positioning. After the embedding cassette is initially positioned, the limiting push plate 5 and the telescopic column 7 work together: the output end of the telescopic column 7 pushes the limiting push plate 5 to move towards the embedding cassette. The inclined auxiliary wedge 6 on the surface of the limiting push plate 5, with its wedge structure, applies lateral pressure to the embedding cassette when it contacts the side of the embedding cassette, and guides the embedding cassette to fine-tune its position so that it is precisely matched with the embedding cassette placement slot 3 and other fixing components.

[0042] The limiting pins 2 at both ends of the limiting base 1 cooperate with the sliding frame 8 on the side. The limiting pins 2 abut against the side wall of the sliding frame 8, thereby limiting the sliding position of the sliding frame 8. The sliding frame 8 on the side of the limiting base 1 can slide along the sliding groove. The auxiliary sliding column 9 at its top is slidably connected to the connecting cover 10. The auxiliary sliding column 9 cooperates with the connecting cover 10 through an internal spring to provide pressure to the top of the embedding box. As the connecting cover 10 provides the upper pre-tightening force, it further assists in clamping the embedding box. It works with the limiting push plate 5 to complete the lateral fixation. The thickened silicone pad 11 slidably connected inside the connecting cover 10, with the help of the elasticity of silicone and the anti-slip properties of the surface, fits the top of the embedding box. The thickened silicone pad 11 is aligned with the opening of the connecting cover 10 to avoid obstructing the operating area of ​​the embedding box and increase the overall practicality.
