[0032] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0033] It should be understood that references throughout this specification to "one embodiment" or "an embodiment" mean that a particular feature, structure, or characteristic associated with the embodiment is included in at least one embodiment of the present invention. Therefore, the appearances of "in one embodiment" or "in an embodiment" throughout this specification do not necessarily refer to the same embodiment. Furthermore, these particular features, structures, or characteristics may be combined in any suitable manner in one or more embodiments.

[0034] The present invention provides a centrifugal sediment transfer tool for transferring centrifugal sediment in a centrifuge tube. Figures 1 to 8 As shown, the centrifugal sediment transfer tool includes:

[0035] The tool handle 1 and the carrier 2 are arranged at the end of the tool handle 1. The carrier 2 is in a spoon-shaped structure and is made of a flexible material.

[0036] The carrier 2 includes a first form and a second form. In the first form, the carrier 2 extends into the centrifuge tube, the carrier 2 is in a deformed state, the outer surface of the carrier 2 is attached to the tube wall of the centrifuge tube, and the curvature of the outer surface of the carrier 2 is consistent with the curvature of the inner wall of the centrifuge tube. In the second form, the carrier 2 and the centrifuge tube are in a separated state, and the carrier 2 is in a restored deformation state, wherein the outer surface and the surface of the carrier 2 on which the centrifugal sediment is placed are two opposite surfaces of the carrier 2.

[0037] As can be seen from the above embodiment, in the embodiment of the present invention, due to the tool handle 1 and the carrier 2 provided at the end of the tool handle 1, the carrier 2 is in a spoon-shaped structure and is made of a flexible material. Therefore, when the centrifugal sediment in the centrifuge tube needs to be transferred, the carrier 2 can be inserted into the centrifuge tube and placed in a first shape, that is, the carrier 2 is in a deformed state, so that the outer surface of the carrier 2 is attached to the wall of the centrifuge tube, and the curvature of the outer surface of the carrier 2 is consistent with the curvature of the inner wall of the centrifuge tube, thereby forming a collection cavity for accommodating and limiting the centrifugal sediment. While expanding the contact area between the carrier 2 and the centrifugal sediment, the sediment is prevented from falling off the carrier 2, and during the transportation process, the carrier 2 can be prevented from applying force to the centrifugal sediment, thereby ensuring the integrity of the centrifugal sediment structure. After being transferred out of the centrifuge tube, the carrier 2 can be placed in a second shape, in which the carrier 2 is in a restored deformed state, which is convenient for the next transfer. To sum up, when the centrifugal sediment transfer tool provided by the new embodiment of the present invention is used to transfer the centrifugal sediment, not only can the integrity of the centrifugal sediment structure be guaranteed, but also the carrier 2 can be deformed according to the shape of the centrifuge tube during the transfer process, thereby avoiding the loss of centrifugal sediment due to contact with the centrifuge tube, and ensuring the accuracy of subsequent detection of the centrifugal test object.

[0038] The tool handle 1 and the carrier 2 in the embodiment of the present invention may be separate structures or integral structures, and the embodiment of the present invention does not limit this.

[0039] In some embodiments, the bearing surface of the carrier 2 is provided with a plurality of raised stripes 21, and the plurality of raised stripes 21 are arranged along a first direction, wherein the first direction is the extension direction from the tool handle 1 to the carrier 2, wherein the bearing surface is the surface of the carrier 2 on which the centrifugal sediment is placed.

[0040] In this embodiment, the supporting surface of the carrier 2 is provided with a plurality of raised stripes 21. These raised stripes 21 are arranged along a first direction (the first direction being the direction extending from the tool handle 1 to the carrier 2). The supporting surface is the surface of the carrier 2 on which the centrifugal sediment is placed. This increases the surface friction of the surface of the carrier 2 on which the centrifugal sediment is placed, thereby increasing the friction between the centrifugal sediment and the supporting surface, reducing the centrifugal sediment from sliding on the supporting surface, and preventing the sediment from falling off the carrier 2. It should be noted that the raised stripes 21 are arranged along the first direction, which can be understood as each raised stripe 21 extending along the first direction, i.e., each raised stripe 21 extends from the end of the carrier 2 closest to the tool handle 1 to the end of the carrier 2 away from the tool handle 1. The multiple raised stripes 21 can be arranged at equal intervals. In this way, the centrifugal sediment can be separated from the carrier 2 along the raised stripes 21, preventing the centrifugal sediment from adhering to the supporting surface of the carrier 2.

[0041] In some embodiments, the bearing surface of the carrier 2 is provided with a flexible coating 22 .

[0042] In this embodiment, since the bearing surface of the carrier 2 is provided with a flexible coating 22, the friction force of the surface of the carrier 2 on which the centrifugal sediment is placed can also be increased, thereby increasing the friction force between the centrifugal sediment and the bearing surface, reducing the sliding of the centrifugal sediment on the bearing surface, and preventing the centrifugal sediment from falling off the carrier 2. It should be noted that the flexible coating 22 can be a polyurethane coating, a PTFE coating, a silicone coating, an acrylic coating, a polyethylene coating, etc. In this way, the flexible coating 22 further increases the overall flexibility of the carrier 2, and the flexible coating 22 reduces the stress of the carrier 2 on the centrifugal sediment, thereby ensuring the integrity of the centrifugal sediment structure.

[0043] In some embodiments, the tool handle 1 includes an outer tube 11 and an inner tube 12; the inner tube 12 is movably connected in the outer tube 11, and the size of the inner tube 12 in the first direction and the sum of the size of the inner tube 12 in the first direction are adjustable, wherein the first direction is the extension direction of the axis of the outer tube 11.

[0044] In this embodiment, the inner tube 12 and the outer tube 11 can be movably connected by a threaded connection, or can be movably connected by a sliding connection, or can be movably connected by other driving methods, which are not limited in the embodiments of the present invention. For example, in the case where the inner tube 12 and the outer tube 11 can be movably connected by a threaded connection, an internal thread can be provided on the inner wall of the end of the outer tube 11, and an external thread can be provided on the outer wall of the inner tube 12, and the size of the inner tube 12 in the first direction and the sum of the size of the inner tube 12 in the first direction can be controlled by controlling the number of threads of the threaded connection between the internal thread and the external thread. For example, in the case where the inner tube 12 and the outer tube 11 are movably connected by a driving method, a spring booster can be provided at the end of the inner tube 12, and the expansion and contraction can be achieved by the compression and recovery of the spring provided inside the outer tube 11, thereby adjusting the size of the inner tube 12 in the first direction and the sum of the size of the inner tube 12 in the first direction. In this way, since the size of the inner tube 12 in the first direction and the sum of the sizes of the inner tube 12 in the first direction are adjustable, when the size of the tool handle 1 in the first direction is not enough, or in other words, when the tool handle 1 cannot adapt to the size of the centrifuge tube, the size of the inner tube 12 in the first direction and the sum of the sizes of the inner tube 12 in the first direction can be changed, thereby adjusting the size of the tool handle 1 in the first direction, so that the tool handle 1 can adapt to a variety of application scenarios.

[0045] In some embodiments, the tool handle 1 includes a first straight rod 13, a second straight rod 14 and a flexible curved rod 15; one end of the flexible curved rod 15 is connected to the first straight rod 13, and the other end of the flexible curved rod 15 is connected to the second straight rod 14, and the bending angle of the flexible curved rod 15 is adjustable.

[0046] In this embodiment, the flexible curved rod 15 can be a rod-shaped structure made of a flexible material, such as a rod-shaped structure made of polyester, polyimide, PTFE, fluorinated polymer, etc. The flexible curved rod 15 can also include multiple curved bodies, which are connected end to end. The bending angle of the flexible curved rod 15 can be adjusted by changing the bending angle between two adjacent curved bodies. In this way, because one end of the flexible curved rod 15 is connected to the first straight rod 13 and the other end of the flexible curved rod 15 is connected to the second straight rod 14, the bending angle of the flexible curved rod 15 is adjustable. Therefore, by deforming the flexible curved rod 15, it can be adapted to application scenarios that require the tool handle 1 to bend, thereby unlimitedly limiting the use scenarios of the centrifugal sediment transfer tool.

[0047] In some embodiments, the transfer tool further comprises a push rod structure 3, the tool handle 1 is internally provided with a through hole extending in the first direction, the through hole extends to the carrier 2; the push rod structure 3 comprises a push rod 31 and a push plate 32, the first end of the push rod 31 extends into the inner cavity of the through hole and is connected with the push plate 32, the push plate 32 is located at the aperture of the through hole towards the carrier 2, the second end of the push rod 31 extends out of the aperture of the through hole away from the carrier 2, and the first end and the second end of the push rod 31 are two ends opposite in the first direction, wherein the first direction is consistent with the extension direction of the tool handle 1.

[0048] In this embodiment, since the push rod structure 3 comprises the push rod 31 and the push plate 32, the first end of the push rod 31 extends into the inner cavity of the through hole and is connected with the push plate 32, the push plate 32 is located at the aperture of the through hole towards the carrier 2, the second end of the push rod 31 extends out of the aperture of the through hole away from the carrier 2, and the first end and the second end of the push rod 31 are two ends opposite in the first direction, therefore when it is needed to transfer the centrifugal precipitate placed on the carrier 2 to other parts, such as to the embedding box, the push rod 31 can be used to push the push plate 32 to move in the first direction, so that the push plate 32 pushes the centrifugal precipitate to separate from the carrier 2, thereby realizing the automatic transfer of the centrifugal precipitate while avoiding the centrifugal precipitate from adhering to the carrying surface, thereby ensuring the accuracy of subsequent detection of the centrifugal detection object.

[0049] In some embodiments, the push rod structure 3 further comprises a driving member, the driving member and the second end of the push rod 31 are drivingly connected, wherein the driving member is used to drive the push rod 31 to move in the first direction.

[0050] In this embodiment, the driving member can be a cylinder push rod structure 3, or a motor lead screw structure, or other structures that can realize movement, and the embodiments of the utility model do not limit this. Exemplarily, taking the driving member as the cylinder push rod structure 3 as an example, the push rod of the cylinder can be connected with the first end of the push rod 31, and the push rod of the cylinder can drive the push rod 31 to move in the first direction through the extension and retraction of the push rod. In this way, since the driving member and the second end of the push rod 31 are drivingly connected, the driving member can drive the push rod 31 to move in the first direction, thereby realizing the automatic transfer of the centrifugal precipitate.

[0051] In some embodiments, the cross-sectional shape of the carrier 2 is oval, wherein the cross-sectional shape is the shape of the outline formed by the mouth of the carrier 2.

[0052] In this embodiment, since the cross-sectional shape of the carrier 2 is oval, the cross-sectional shape is the shape of the outline formed by the mouth of the carrier 2, so that the carrier 2 constitutes a one-aperture structure from the end far away from the tool handle 1 to the end close to the tool handle 1, that is, the carrier 2 can form a wrapping cavity structure after deformation, so that the centrifugal precipitate can be collected in the carrier 2, and further avoid the centrifugal precipitate from falling off from the carrier 2.

[0053] In some embodiments, the material of the carrier 2 includes smart memory alloy or elastic polymer.

[0054] In this embodiment, since the smart memory alloy or the elastic polymer has the advantages of high elasticity, high strength, wear resistance and chemical corrosion resistance, when the material of the carrier 2 includes the smart memory alloy or the elastic polymer, not only can the carrier 2 be deformed under the extrusion of external force, but also can be restored after the external force is removed, that is, the carrier 2 can switch between the first mode and the second mode. At the same time, the material of the carrier 2 can avoid reacting with the centrifugal precipitate, thereby ensuring the structural integrity of the centrifugal precipitate.

[0055] It should be noted that the use effect of the centrifugal precipitate transfer tool provided by the embodiment of the utility model is illustrated by taking the preparation process of the cell wax block as an example. When the centrifugal precipitate (cell wax block) in the centrifugal tube needs to be transferred to the embedding box, at least the following effects are achieved: 1. The deformation ability of the carrier 2 when contacting the centrifugal tube effectively expands the contact area with the centrifugal precipitate, which can improve the collection efficiency of the centrifugal precipitate, especially when dealing with trace or fragile samples, can significantly reduce the loss of cell and tissue fragments, and maintain the original integrity of the sample. 2. Since the centrifugal precipitate is reduced in the transfer and embedding process, the structure of the finally prepared cell wax block is more compact and uniform, the deformation and loss of the tissue in the subsequent dehydration and wax immersion process are reduced, and the overall quality and uniformity of the wax block are directly improved, which lays a good foundation for the subsequent slicing and staining steps.

[0056] 3. The accuracy of subsequent detection of the centrifugal precipitate can be ensured.

[0057] As can be seen from the above embodiment, in the embodiment of the present invention, due to the tool handle 1 and the carrier 2 provided at the end of the tool handle 1, the carrier 2 is in a spoon-shaped structure and is made of a flexible material. Therefore, when the centrifugal sediment in the centrifuge tube needs to be transferred, the carrier 2 can be inserted into the centrifuge tube and placed in a first shape, that is, the carrier 2 is in a deformed state, so that the outer surface of the carrier 2 is attached to the wall of the centrifuge tube, and the curvature of the outer surface of the carrier 2 is consistent with the curvature of the inner wall of the centrifuge tube, thereby forming a collection cavity for accommodating and limiting the centrifugal sediment. While expanding the contact area between the carrier 2 and the centrifugal sediment, the sediment is prevented from falling off the carrier 2, and during the transportation process, the carrier 2 can be prevented from applying force to the centrifugal sediment, thereby ensuring the integrity of the centrifugal sediment structure. After being transferred out of the centrifuge tube, the carrier 2 can be placed in a second shape, in which the carrier 2 is in a restored deformed state, which is convenient for the next transfer. To sum up, when the centrifugal sediment transfer tool provided by the new embodiment of the present invention is used to transfer the centrifugal sediment, not only can the integrity of the centrifugal sediment structure be guaranteed, but also the carrier 2 can be deformed according to the shape of the centrifuge tube during the transfer process, thereby avoiding the loss of centrifugal sediment due to contact with the centrifuge tube, and ensuring the accuracy of subsequent detection of the centrifugal test object.

[0058] It should be noted that the various embodiments in this specification are described in a progressive manner, and each embodiment focuses on the differences from other embodiments. The same and similar parts between the various embodiments can be referenced to each other.

[0059] Although alternative embodiments of the present invention have been described, those skilled in the art may make additional changes and modifications to these embodiments once they have learned the basic creative concept. Therefore, the appended claims are intended to be interpreted as including alternative embodiments and all changes and modifications that fall within the scope of the present invention.
