[0024] Embodiments of the present invention are described in detail below, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and cannot be understood as limiting the present invention.

[0025] Reference below Figure 1-Figure 3 An anchoring device 1 for a skin model according to an embodiment of the present invention is described.

[0026] The anchoring device 1 for a skin model according to an embodiment of the present invention is as follows: Figure 1-Figure 3 As shown, the anchoring device 1 for the skin model may include: a mounting seat 10 and a plurality of limiting columns 20, the plurality of limiting columns 20 are all fixedly mounted on the mounting seat 10, and the plurality of limiting columns 20 are located on the same side of the mounting seat 10, the plurality of limiting columns 20 are arranged along the circumference of the mounting seat 10, and the plurality of limiting columns 20 are all used to be embedded in the skin model to limit the wrinkling of the skin model.

[0027] It should be noted that in the related art, the existing skin models are prone to shrinkage, have poor stability, and have a short effective time, which affects the cost and efficiency of related experiments using the skin models.

[0028] Based on this, the embodiment of the present application proposes an anchoring device 1 for a skin model. When the anchoring device 1 is placed in the up-down direction, the mounting seat 10 is located at the bottom of the anchoring device 1. The mounting seat 10 can be used to support multiple limiting columns 20. The cross-sectional shape of the mounting seat 10 can be circular. Multiple limiting columns 20 can be fixedly connected to the mounting seat 10, and multiple limiting columns 20 can be integrally formed with the mounting seat 10. As an example, the anchoring device 1 can be made by 3D printing. As another example, the anchoring device 1 can be made by injection molding. Along the height direction of the anchoring device 1, multiple limit columns 20 can be located on the same side of the mounting seat 10, and multiple limit columns 20 can be arranged along the circumference of the mounting seat 10. The height of each limit column 20 can be greater than or equal to the thickness of the skin model. Multiple limit columns 20 can be embedded in the skin model. Multiple limit columns 20 can play a role in pulling the skin model, so that the skin model located on the inner side of the multiple limit columns 20 is always unfolded, thereby limiting the shrinkage of the skin model along the circumference of the mounting seat 10, which is beneficial to improve the stability of the skin model, extend the effective time of the skin model, ensure the effectiveness of skin model-related applications, and reduce the impact on related experiments.

[0029] It should be noted that, along the radial direction of the anchor device 1 , the side close to the center of the anchor device 1 is the inner side, and the side away from the center of the anchor device 1 is the outer side.

[0030] As an example, the anchoring device 1 can be used to limit the shrinkage of the dermis model. After the anchoring structure is ultraviolet sterilized, the anchoring structure can be placed in the model carrier first, and then the dermis extracellular matrix hydrogel is added to the model carrier to construct the dermis model. When verifying the specific effect of the anchoring device 1, a comparative experiment of using the anchoring device 1 to construct the dermis model and not using the anchoring device 1 to construct the dermis model can be set. On the 4th day of culturing the dermis model, the dermis model in the model carrier without the anchoring device 1 has shrunk severely, and the area of ​​the dermis model has been greatly reduced, while the dermis model using the anchoring device 1 has not shrunk. On the 14th day of culturing the dermis model, there is no obvious tissue in the model carrier without the anchoring device 1, and the dermis model using the anchoring device 1 still has no obvious shrinkage. Multiple limiting posts 20 are embedded in the dermis model, and multiple limiting posts 20 can be used together to limit the shrinkage of the dermis model. The edge position of the dermis model can always be located outside the anchoring device 1, thereby extending the effective time of the dermis model, which is conducive to improving the stability of the dermis model.

[0031] In some embodiments of the present invention, one end of the limiting column 20 is fixedly connected to the mounting seat 10 , and the limiting column 20 and the mounting seat 10 are perpendicular.

[0032] The limiting column 20 can be arranged perpendicularly to the mounting seat 10, the limiting column 20 can extend along the height direction of the anchoring device 1, one end of the limiting column 20 can be fixedly connected to the mounting seat 10, and the other end of the limiting column 20 can extend in a direction away from the mounting seat 10. Multiple limiting columns 20 can be arranged in the skin model along the thickness direction of the skin model (i.e., the height direction of the anchoring device 1), and multiple limiting columns 20 can play the role of fixing and supporting the skin model. By setting multiple limiting columns 20 perpendicular to the mounting seat 10, the probability of the skin model being offset or deformed can be reduced, which is conducive to improving the stability of the skin model.

[0033] In some embodiments of the present invention, a plurality of limiting posts 20 are parallel to each other.

[0034] Multiple limiting posts 20 can be arranged along the circumference of the mounting seat 10, and the multiple limiting posts 20 are perpendicular to the mounting seat 10, and the multiple limiting posts 20 are parallel to each other, so that the contraction of the skin model in all directions along the circumference of the mounting seat 10 is limited, which is beneficial to maintaining the overall structure and function of the skin model and ensuring the effectiveness of the skin model.

[0035] In some embodiments of the present invention, the limiting column 20 may include: a rod portion 21 and a head portion 22 , the rod portion 21 is connected between the mounting seat 10 and the head portion 22 , and the cross-sectional area of ​​the head portion 22 is greater than the cross-sectional area of ​​the rod portion 21 .

[0036] The rod 21 and the head 22 can be arranged along the height direction of the anchoring device 1, and the rod 21 can be connected between the mounting seat 10 and the head 22, and the rod 21 and the head 22 can be integrally formed. The rod 21 can abut against the skin model, and the rod 21 has the effect of limiting the shrinkage of the skin model. The cross-sectional area of ​​the head 22 is larger than the cross-sectional area of ​​the rod 21, and the head 22 can limit the skin model along the height direction of the anchoring device 1, reduce the probability of the skin model escaping from the head 22, so that the limiting column 20 can always be embedded in the skin model, so that the limiting column 20 can always support the skin model.

[0037] In some embodiments of the present invention, the head 22 is spherical.

[0038] The head 22 can be spherical, and the surface of the spherical head 22 is smooth. When the limiting column 20 is embedded in the skin model and the head 22 abuts against the skin model, the probability of the head 22 damaging the skin model can be reduced. In addition, the spherical head 22 can reduce complex structural designs, making the structure of the limiting column 20 simpler and easier to manufacture and maintain.

[0039] In some embodiments of the present invention, a connecting platform 23 is formed at the end of the rod 21 away from the head 22. The connecting platform 23 is fixedly connected to the mounting seat 10. The cross-sectional area of ​​the connecting platform 23 gradually increases from the limiting column 20 to the mounting seat 10.

[0040] Along the height direction of the anchoring device 1, a connecting platform 23 is formed at the end of the rod 21 away from the head 22. The connecting platform 23 is connected between the rod 21 and the mounting seat 10. The connecting platform 23 can be integrally formed with the mounting seat 10. The connecting platform 23 can play a role in supporting the rod 21, thereby improving the stability of the limiting column 20 when limiting the shrinkage of the skin model. From the limiting column 20 to the mounting seat 10, the cross-sectional area of ​​the connecting platform 23 gradually increases, and the cross-sectional area of ​​the end where the connecting platform 23 and the mounting seat 10 are connected is larger than the cross-sectional area of ​​the end where the connecting platform 23 and the rod 21 are connected. The contact area between the connecting platform 23 and the mounting seat 10 is larger, which can further provide stable support for the limiting column 20.

[0041] In some embodiments of the present invention, the connecting platform 23 is configured as a truncated cone.

[0042] Along the height direction of the anchor device 1, the upper surface of the connecting platform 23 can be connected to the rod 21, and the cross-sectional area of ​​the upper surface of the connecting platform 23 can be equal to the cross-sectional area of ​​the rod 21, so that the connection between the rod 21 and the connecting platform 23 is smooth, which is conducive to improving the structural integrity of the limiting column 20. The lower surface of the connecting platform 23 is connected to the mounting seat 10, and the cross-sectional area of ​​the lower surface of the connecting platform 23 is greater than the cross-sectional area of ​​the upper surface of the connecting platform 23, which increases the contact area between the limiting column 20 and the mounting seat 10, enhances the supporting capacity of the mounting seat 10 to the limiting column 20, and is conducive to improving the stability of the overall structure of the anchor device 1.

[0043] In some embodiments of the present invention, the mounting seat 10 is configured as an annular structure to define a through hole 11 , and a plurality of limiting columns 20 are arranged around the through hole 11 along the circumference of the mounting seat 10 .

[0044] A through hole 11 is formed on the mounting seat 10. The through hole 11 can penetrate the mounting seat 10 along the thickness direction of the mounting seat 10 (i.e., the height direction of the anchoring device 1). The through hole 11 can be coaxially arranged with the mounting seat 10, and the mounting seat 10 can be constructed in a ring shape. When the anchoring device 1 is embedded in the skin model, the experimenter can observe the skin model through the through hole 11, and the mounting seat 10 will not cover the skin model, which is convenient for the experimenter to observe the skin model. A plurality of limiting columns 20 can be arranged around the through hole 11 along the circumference of the mounting seat 10, so as to achieve the effect of limiting the shrinkage of the skin model along the circumference of the mounting seat 10, which is conducive to prolonging the effectiveness of the skin model.

[0045] In some embodiments of the present invention, a plurality of limiting pillars 20 form a plurality of limiting pillar groups, and the plurality of limiting pillar groups are evenly arranged along the circumference of the mounting seat 10 , and each limiting pillar group includes at least one limiting pillar 20 .

[0046] By dividing a plurality of limiting columns 20 into a plurality of limiting column groups, each limiting column group including at least one limiting column 20, it can be achieved that when some limiting columns 20 are damaged, the anchoring device 1 can still play the role of limiting the shrinkage of the skin model, which is beneficial to extending the service life of the anchoring device 1. The plurality of limiting column groups can be evenly arranged along the circumference of the mounting seat 10. As an example, the limiting columns 20 of the plurality of limiting column groups can be located on the same circumference. As another example, the limiting columns 20 of the plurality of limiting column groups can be staggered along the circumference of the mounting seat 10. By setting the plurality of limiting column groups to be evenly arranged along the circumference of the mounting seat 10, the skin model can be subjected to uniform force, which is beneficial to ensure the ductility of the skin model along the circumference of the mounting seat 10.

[0047] In some embodiments of the present invention, each group of limiting column groups includes a plurality of limiting columns 20 , and at least two limiting columns 20 in each group of limiting column groups are staggered along the circumferential direction of the mounting seat 10 .

[0048] Each group of limiting column groups includes a plurality of limiting columns 20. Some limiting columns 20 in each group of limiting column groups can be located on the same circle, and another part of limiting columns 20 in each group of limiting column groups can be located on another circle. The radii of the two circles can be different, and the two circles can be coaxially arranged with the mounting seat 10, so that at least two limiting columns 20 in each group of limiting column groups can be staggered along the circumference of the mounting seat 10. The staggered limiting columns 20 can avoid the force being concentrated on a certain point, so that the skin model can be more evenly stressed, reduce the probability of skin model damage caused by excessive local stress, and enhance the stability of the skin model. Moreover, the central axes of the limiting columns 20 located on the same circle in multiple groups of limiting column groups can be located on the same circle, so that the structures of the multiple groups of limiting column groups are the same, which is conducive to improving the stability of the multiple limiting columns 20 when limiting the shrinkage of the skin model.

[0049] The embodiment of the present application is explained by taking the example that each group of limit column groups includes three limit columns 20, one of the limit columns 20 in each group of limit column groups is staggered along the circumference of the mounting seat 10 with the other two limit columns 20, one of the limit columns 20 in each group of limit column groups is located on the first circle, and the other two limit columns 20 in each group of limit column groups are located on the second circle, the radius of the second circle can be greater than the radius of the first circle, the first circle and the second circle can be coaxially arranged with the mounting seat 10, thereby achieving the effect of at least two limit columns 20 in each group of limit column groups being staggered along the circumference of the mounting seat 10, which is beneficial to improving the supporting ability of the anchoring device 1 on the skin model and improving the stability of the skin model. Each of the multiple groups of limiting column groups has a limiting column 20 located on the first circle, and each of the multiple groups of limiting column groups has two limiting columns 20 located on the second circle. The central axes of the multiple limiting columns 20 located on the first circle can all be located on the first circle, and the central axes of the multiple limiting columns 20 located on the second circle can all be located on the second circle. The structures of the multiple groups of limiting column groups are the same, thereby ensuring that the anchoring device 1 uniformly supports the skin model along the circumference of the mounting seat 10, which is beneficial to improving the stability of the multiple limiting columns 20 when limiting the wrinkling of the skin model.

[0050] In some embodiments of the present invention, the sizes of various parts of the anchoring device can be flexibly adjusted according to the sizes of different skin models, so that the anchoring device can adapt to the structure of the skin model, so that the skin model can better assist subsequent experiments, which is conducive to improving the versatility of the anchoring device.
