Description

Technical Field

[0001] The invention belongs to the field of specimen collection, and in particular relates to a wax roll specimen collection device for molecular pathology detection. Background Art

[0002] Molecular pathology testing plays a key role in modern medical diagnosis and treatment. Through molecular level analysis of pathological tissue, we can gain in-depth understanding of the disease's pathogenesis, development process and patient prognosis. The wax roll specimen collection device for molecular pathology testing is a tool specifically used to collect wax roll specimens of pathological tissue. In the process of molecular pathology testing, paraffin-embedded tissue is a common source of testing materials. Wax rolls are thin rolls of tissue cut from paraffin-embedded tissue blocks. The purpose of this collection device is to safely and effectively collect wax rolls for subsequent testing and analysis, such as detecting mutations in tumor-related genes.

[0003] A Chinese patent with patent announcement number CN219416938U discloses a wax roll specimen collection device for molecular pathology testing. The device avoids the possibility of cross-contamination such as splashing of wax roll specimens during routine operations by designing a unique plug at the mouth of the test tube. Wax scraps and samples will not stick to the mouth of the tube, avoiding the loss of small samples and the leakage of reagents such as xylene from the tube, which is conducive to environmental cleanliness and safe operation. However, the structure of the device is relatively simple and cannot adapt well to wax rolls of different sizes and shapes.

DETAILED DESCRIPTION

[0042] The present invention will now be described in further detail with reference to the accompanying drawings.

[0043] See also Figure 1-9 As shown, in this embodiment, a wax roll specimen collection device for molecular pathology detection is provided, including a device body 1, which is detachably connected to a cover plate 2, and the device body 1 is divided into a plurality of chambers 12 by a partition plate 6, and each chamber 12 is fixedly connected with a placement tube 14, and a clamping plate 10 is fixedly connected to the top of the placement tube 14 along its circumference direction through an elastic sheet 26, and a driving component 9 is provided in the chamber 12 for driving the plurality of clamping plates 10 to move relative to the entrance direction of the placement tube 14. The driving component 9 includes a movable collar 91, and its sleeve It is provided and movably arranged on the placement tube 14, and a lifting mechanism 92 is provided in the chamber 12 for driving the movable collar 91 to move longitudinally along the placement tube 14. The movable collar 91 is rotatably connected along its circumference direction with a first connecting rod 94 equal to a plurality of clamping plates 10, and a fixed rod 93, which is fixedly connected to the placement tube 14. The fixed rod 93 is arranged equal to the clamping plates 10, and a second connecting rod 95 is movably connected to the fixed rod 93. The two ends of the second connecting rod 95 are respectively hinged to the clamping plates 10 and one end of the first connecting rod 94 away from the movable collar 91.

[0044] The movable sleeve 91 is driven by the lifting mechanism 92 to move upward along the placing tube 14. When the movable sleeve 91 moves, the second connecting rod 95 is driven by the first connecting rod 94 to rotate around the fixed rod 93. The rotation of the second connecting rod 95 further drives the plurality of clamping plates 10 to move relative to the entrance direction of the placing tube 14 to achieve the clamping and positioning of the wax roll specimen. The setting of the elastic sheet 26 enables the clamping plate 10 to maintain a certain elasticity during the movement and to rotate around the placing tube 14. At the same time, it can drive the clamping plate 10 to reset when the movable sleeve 91 moves downward. The overall operation steps are simple. The driving assembly 9 can achieve stable clamping of wax roll specimens of different sizes and shapes, prevent the wax roll from being displaced or falling during the collection and transportation process, and improve the safety and reliability of wax roll collection and transportation. At the same time, the design of the multi-chamber 12 can collect multiple wax roll specimens at the same time, thereby improving the collection efficiency.

[0045] It should be noted that, in the present embodiment, the two ends of the elastic sheet 26 are fixedly connected to the placement tube 14 and the clamping plate 10 respectively, and the lifting mechanism 92 is a mechanism that can drive the movable ring 91 to move and limit the longitudinal direction of the placement tube 14, such as an electric lifting rod, or manually adjust the position of the movable ring 91, and then position it through a positioning pin; secondly, in the present embodiment, the number of clamping plates 10 is three groups, and relatively, the first connecting rod 94, the second connecting rod 95 and the fixed rod 93 are all three. Of course, in other embodiments, the quantity can be adjusted according to actual conditions, and there is no limitation here. The material of the elastic sheet 26 is preferably spring steel, and in other embodiments it can be plastic, etc.; further, the material of the device body 1 and the placement tube 14 is preferably plastic.

[0046] In this embodiment, if Figure 2 , Figure 6 and Figure 8As shown, the lifting mechanism 92 includes a fixed plate 922, which is fixedly connected to the inner wall of the device body 1, and a threaded rod 921 is rotatably connected to the fixed plate 922, and a slider 923 is sleeved and threadedly connected to the threaded rod 921. The first end of the slider 923 is slidably set on the device body 1, and the device body 1 is provided with a slide groove 13 for the slider 923 to slide. The second end of the slider 923 is fixedly connected to the movable collar 91. Specifically, when the movable collar 91 needs to be adjusted, by rotating the threaded rod 921, since the slider 923 is threadedly connected to the threaded rod 921, and the first end of the slider 923 slides in the slide groove 13 of the device body 1, under the rotation of the threaded rod 921, The slider 923 moves along the direction of the threaded rod 921, thereby driving the movable ring 91 to move on the placement tube 14; it should be noted that a toggle groove 11 is embedded in the driving end of the threaded rod 921. The setting of the toggle groove 11 is convenient for the user to insert a specific structure into the toggle groove 11 to drive the threaded rod 921 to rotate under specific circumstances. For example, when it is inconvenient for the user to drive the threaded rod 921 to rotate with his hands, the user can insert a stick-shaped rod body into the toggle groove 11 to drive the threaded rod 921 to rotate. Of course, in other embodiments, the toggle groove 11 can also be a groove body matching a structure such as a screwdriver, which can be adjusted according to actual conditions and is not restricted here.

[0047] In this embodiment, if Figure 6 and Figure 7 As shown, the fixed rod 93 is movably connected to the second connecting rod 95 through the fixed shaft 19. The second connecting rod 95 is provided with a movable groove 18 for the fixed shaft 19 to move. The movable groove 18 is arranged along the length direction of the second connecting rod 95. Specifically, when the second connecting rod 95 rotates, the fixed shaft 19 moves in the movable groove 18, so that the movement of the second connecting rod 95 is more flexible, which can better drive the movement of the clamping plate 10, thereby improving the movement accuracy of the clamping plate 10.

[0048] In this embodiment, if Fig. 9 As shown, a supporting block 20 is fixedly connected to the bottom of the placement tube 14, and a supporting groove 21 is embedded in the supporting block 20. A sponge cover 22 is fixedly connected to the inner wall of the placement tube 14, and a plurality of sponge strips 23 are fixedly connected to the sponge cover 22. Specifically, the supporting block 20 can be made of sponge, silicone, etc. The supporting groove 21 on the supporting block 20 is used to place the wax roll specimen. The sponge cover 22 and the sponge strips 23 can play a role in buffering and protecting the wax roll, preventing the wax roll from being hit or rubbed during the placement process, reducing the damage to the wax roll during the placement process, and improving the quality of the wax roll. At the same time, the presence of the sponge cover 22 and the sponge strips 23 can increase the friction between the wax roll and the placement tube 14, and prevent the wax roll from sliding during the placement process.

[0049] In this embodiment, if Figure 6 and Figure 8As shown, the inner wall of the placement tube 14 between the sponge sleeve 22 and the supporting block 20 is fixedly connected with a plurality of deformable elastic clamps 8 at intervals along the circumference direction thereof, and a driving assembly 9 for driving the plurality of elastic clamps 8 to limit the wax roll specimen in the placement tube 14 is provided in the device body 1, and the driving assembly 9 includes an external gear 71, which is sleeved and rotatably arranged on the outer wall of the placement tube 14, a driving gear 75 meshing with the external gear 71 is sleeved and fixedly connected on the threaded rod 921, and a plurality of movable rods 72, which are movably arranged on the placement tube 14, and the movable rods 72 are connected with the elastic clamps 8. The plurality of movable rods 72 are arranged in equal amounts along the circumference direction of the placement tube 14. The first end of the movable rod 72 is fixedly connected to a push plate 76, and the push plate 76 is fixedly connected to the elastic clamping plate 8. The driving rod 74 is fixedly connected to the second end of the movable rod 72 at one end, and the other end is movably arranged on the outer gear 71. The outer gear 71 is penetrated by a driving groove 73 for the driving rod 74 to move. The driving groove 73 is an arc-shaped groove extending from the inner ring to the outer ring of the outer gear 71. Specifically, when the threaded rod 921 rotates, the driving gear 75 drives the outer gear 71 to rotate, and the outer gear 7 When the drive slot 73 rotates, the drive rod 74 will drive the drive rod 74 to move, so that the drive rod 74 drives the movable rod 72 to move, and the movement of the movable rod 72 pushes the push plate 76, so that the elastic clamping plate 8 is deformed and the wax roll specimen is limited. Through the cooperation of the driving component 9 and the clamping component 7, the wax roll specimen can be fully limited, and the stability of the wax roll can be improved. It should be noted that in this embodiment, the material of the elastic clamping plate 8 is preferably silicone, and in other embodiments it can also be sponge, rubber, etc. At the same time, a material for the movable rod 72 to move is provided through the placement tube 14. Secondly, the moving range of the elastic splint 8 driven by the driving component 9 is matched with the moving direction of the clamping plate 10 driven by the clamping component 7, that is, when the clamping component 7 drives the clamping plate 10 to clamp and position the wax roll specimen, the driving component 9 simultaneously drives the elastic splint 8 to fit the wax roll specimen, that is, to achieve double limiting of the wax roll specimen, improve the stability of the wax roll specimen during transportation, and at the same time be able to adapt to the positioning of wax roll specimens of different sizes. Of course, the sizes and specifications of the components between the driving component 9 and the clamping component 7 can be adjusted according to actual conditions. This is the prior art.

[0050] In this embodiment, if Figure 8 and Fig. 9 As shown, a cavity 17 is defined between the elastic splint 8 and the placement tube 14, and the push plate 76 is located in the cavity 17. The push plate 76 is an arc-shaped structure that can fit with the inner wall of the placement tube 14. Specifically, the cavity 17 provides space for the movement of the movable rod 72 and the push plate 76, so that when the push plate 76 pushes the elastic splint 8, the part of the elastic splint 8 corresponding to the cavity 17 is raised, thereby achieving the clamping and positioning of the wax roll specimen.

[0051] In this embodiment, if Figure 8 and Fig. 9As shown, the clamping plate 10 is an arc-shaped structure, and a sponge plate 24 is fixedly connected to the clamping plate 10. An antistatic coating 25 is sprayed on the sponge plate 24. Specifically, the sponge plate 24 can increase the friction between the clamping plate 10 and the wax roll to prevent the wax roll from sliding during the clamping process, and at the same time play a buffering effect. The antistatic coating 25 can prevent the wax roll from being damaged due to electrostatic adsorption.

[0052] In this embodiment, if Figure 2 , Figure 3 and Figure 4 As shown, an embedding plate 15 with a mouth-shaped structure is fixedly connected to the cover plate 2 along its circumference direction, and an embedding groove 5 for the embedding plate 15 to be embedded is embedded in the device body 1. The cover plate 2 and the device body 1 are detachably connected through the buckle assembly 4. Specifically, by embedding the embedding plate 15 on the cover plate 2 into the embedding groove 5 on the device body 1, the detachable connection between the cover plate 2 and the device body 1 is achieved through the buckle assembly 4. The buckle assembly 4 can easily open and close the cover plate 2, which is convenient for placing and removing wax roll specimens. The design of the embedding plate 15 and the buckle assembly 4 makes the connection between the cover plate 2 and the device body 1 tighter, which can effectively prevent the wax roll specimens from being affected by the external environment. At the same time, the detachable connection facilitates the operation and management of the wax roll specimens. It should be noted that in order to improve the sealing of the connection between the cover plate 2 and the device body 1, a sealing ring can be added at the connection between the two.

[0053] In this embodiment, if Figure 1 and Figure 4 As shown, a resistance block 16 is fixedly connected to the bottom of the cover plate 2 opposite to the entrance of the placement tube 14, and a handle 3 is fixedly connected to the top of the cover plate 2. Specifically, the resistance block 16 can play a certain blocking role after the wax roll is placed, preventing the wax roll from sliding out of the placement tube 14. At the same time, the handle 3 makes it convenient for the operator to lift the cover plate 2 to place and remove the wax roll.

[0054] Working principle:

[0055] By opening the cover plate 2, the wax roll specimen is placed into the placement tube 14 with tweezers. After placement, the threaded rod 921 is rotated. Since the slider 923 is threadedly connected to the threaded rod 921, and the first end of the slider 923 slides in the slide groove 13 of the device body 1, the slider 923 moves along the direction of the threaded rod 921 under the rotation of the threaded rod 921, thereby driving the movable collar 91 to move upward in the placement tube 14. When the movable collar 91 moves, the second connecting rod 95 is driven to rotate around the fixed rod 93 through the first connecting rod 94. The rotation of the second connecting rod 95 further drives the multiple clamping plates 10 to move relative to the entrance direction of the placement tube 14, thereby achieving the clamping and positioning of the wax roll specimen. At the same time, when the threaded rod 921 rotates, the driving gear 75 drives the outer gear 71 to rotate. When the outer gear 71 rotates, the driving groove 73 will drive the driving rod 74 to move, so that the driving rod 74 drives the movable rod 72 to move, and the movement of the movable rod 72 pushes the pushing plate 76, thereby causing the elastic clamping plate 8 to deform and limit the wax roll specimen. Finally, the embedding plate 15 on the cover plate 2 is embedded in the embedding groove 5 on the device body 1, and the cover plate 2 and the device body 1 are connected through the buckle assembly 4. The overall operation steps are simple. The driving assembly 9 can achieve stable clamping of wax roll specimens of different sizes and shapes, preventing the wax roll from being displaced or falling during the collection and transportation process, thereby improving the safety and reliability of wax roll collection and transportation. At the same time, the design of the multi-chamber 12 can collect multiple wax roll specimens at the same time, thereby improving the collection efficiency.
