Description

TECHNICAL FIELD

[0002] The toe nail corrector is mainly applied in the treatment of onychocryptosis. The toe nail corrector is mostly an elastic body made of various materials. When used, an adhesive is applied to the bottom of the toe nail corrector to fix it on the surface of the toe nail. With the help of the elastic body, the toe nail is continuously pulled to change the growth direction, thus achieving the treatment effect.

[0003] However, the toe nail shapes of different patients are generally different. For the toe nail with normal or large surface curvature, the toe nail corrector can ensure the correction effect on the toe nail.

[0046] Referring to Figures 1 to 3 A toe nail corrector 100 according to an embodiment of the present application comprises a corrector body 10, the corrector body 10 is arranged in a curved structure, so that the corrector body 10 has a concave part 11 and a convex part 12 oppositely arranged along the thickness direction of the corrector body 10, the convex part 12 is used to be installed towards the toe nail to be corrected, and the concave part 11 is used to be arranged away from the toe nail, and the corrector body 10 is configured to have elastic performance.

[0047] For example, in order to make the corrector body 10 have excellent elastic performance, the corrector body 10 can be made of any one of stainless steel, nickel-titanium alloy and the like, which can be flexibly selected according to actual needs.

[0048] It is easy to understand that the corrector body 10 is arranged in a curved structure, so that the corrector body 10 is formed into a structure with high ends and low middle.

[0049] In summary, the implementation of the technical scheme of the embodiment will have the following beneficial effects: the toe nail corrector 100 of the present scheme is applied to the treatment occasion of the ingrown toe nail problem of the user, when used, the corrector body 10 is installed on the toe nail with the convex part 12 towards the toe nail to be corrected, because the corrector body 10 is arranged in a curved structure, and the convex part 12 is towards the toe nail while the concave part 11 is away from the toe nail, when installed, the corrector body 10 is pressed (in the direction of the arrow F) to a flat state or even a reverse curved arc state, so that the corrector body 10 can generate greater resilience to the toe nail, thereby forming a more effective pulling correction effect on the ingrown part of the toe nail, and ensuring the treatment ability of the toe nail corrector 100. Figure 2 It is easy to understand that compared with the existing flat structure toe nail corrector 100, the toe nail corrector 100 of the present scheme arranged in a curved structure can generate greater resilience when being pressed and deformed from the curved structure to the flat structure, and this part of resilience additionally acts on the toe nail to be corrected, which can make up for the correction effect caused by the lack of the arc of the flat toe nail.

[0050] It is easy to understand that compared with the existing flat structure toe nail corrector 100, the toe nail corrector 100 of the present scheme arranged in a curved structure can generate greater resilience when being pressed and deformed from the curved structure to the flat structure, and this part of resilience additionally acts on the toe nail to be corrected, which can make up for the correction effect caused by the lack of the arc of the flat toe nail.

[0051] In order to realize the installation of the toe nail corrector 100 on the toe nail to be corrected, in an optional embodiment, the convex part 12 is used to apply adhesive to bond and fix the toe nail corrector 100 on the surface of the toe nail to be corrected.

[0052] The fixing mode of adhesive bonding has simple installation, good connection firmness, does not cause damage to the toe nail, and good user experience. Of course, in other optional embodiments, clamping, vacuum adsorption and the like can be used to replace the installation mode of bonding, which can be selected according to actual needs, and details are not repeated here.

[0053] Please continue to refer to Figures 4 to 12 In another embodiment, the corrector body 10 includes a first part 13 and a second part 14, one end of the first part 13 is connected at an angle with one end of the second part 14. At this time, the sides of the first part 13 and the second part 14 away from the toe nail to be corrected cooperate to form the concave part 11, and the two sides of the first part 13 and the second part 14 facing the toe nail to be corrected cooperate to form the convex part 12, and the overall forming structure of the corrector body 10 is simple.

[0054] Further, on the basis of the above-mentioned embodiments, in another embodiment, the first part 13 is provided with a first rotating part 131 near one end of the second part 14, and the second part 14 is provided with a second rotating part 141 near one end of the first part 13, and the first rotating part 131 is directly connected with the second rotating part 141 or indirectly connected with the second rotating part 141 through a rotating shaft body.

[0055] Through the direct connection of the first rotating part 131 with the second rotating part 141 or the indirect connection of the first rotating part 131 with the second rotating part 141 through the rotating shaft body, when installing, the first part 13 and the second part 14 can be rotated with the center of the rotating structure formed by the first rotating part 131, the second rotating part 141 or the first rotating part 131, the rotating shaft body and the second rotating part 141 as the center of rotation, so as to deform in a flat or reverse curved arc state, so as to produce a better rebound pulling correction effect on the toe nail.

[0056] In addition, in another optional embodiment, the corrector body 10 further includes a connecting part 15 connected between the first part 13 and the second part 14, and the first part 13 and the second part 14 are both bent towards the same side of the connecting part 15. On the one hand, the connecting part 15 connects the first part 13 and the second part 14, avoiding the formation of sharp corners between the first part 13 and the second part 14, which helps to reduce stress concentration and eliminate the potential risk of fracture after long-term compression deformation; on the other hand, the connecting part 15 increases the contact support area with the toe nail to be corrected, so as to more conveniently install, position and bond the toe nail corrector 100.

[0057] Please continue to refer to Figures 5 to 7 Optionally, in some embodiments, the connecting portion 15 is provided in a flat, arched or corrugated structure. In this way, the toe nail corrector 100 can form a series of products with different appearance configurations to meet the different preferences of different users.

[0058] More specifically, when the connecting portion 15 is arched, the concave arch surface is used to face the toe nail to be corrected during installation of the toe nail corrector 100, and the convex arch surface is used to face away from the toe nail.

[0059] However, it should be noted that the connecting portion 15 can also be any other shape configuration in other optional embodiments, which can be designed flexibly according to actual needs, and will not be described here.

[0060] Please continue to refer to Figures 8 to 11 In addition, in another embodiment, the toe nail corrector 100 further comprises a support body 20, the support body 20 is used to abut against the toe nail to be corrected, one end of the first portion 13 close to the second portion 14 is connected with the support body 20, and one end of the second portion 14 close to the first portion 13 is connected with the support body 20. The support body 20 provided can increase the support contact area with the toe nail to be corrected, thereby helping to improve the positioning reliability and bonding firmness of the toe nail correction.

[0061] Alternatively, the toe nail corrector 100 further comprises a support body 20, the support body 20 has an adhesive surface for bonding with the toe nail to be corrected, one end of the first portion 13 close to the second portion 14 is connected with the support body 20, and one end of the second portion 14 close to the first portion 13 is connected with the support body 20. The support body 20 provided can increase the support and bonding area with the toe nail to be corrected, thereby helping to improve the positioning reliability and bonding firmness of the toe nail correction.

[0062] For example, the support body 20 can be connected with the first portion 13 and the second portion 14 integrally or detachably assembled by at least one process such as gluing, clamping, screwing, etc., which can be selected flexibly according to actual needs, and will not be specifically limited here.

[0063] Optionally, the support body 20 is made of a material with certain elastic ability, such as plastic, silicone, etc., so as to have certain elastic deformation performance, adapt to the reverse bending deformation of the first portion 13 and the second portion 14, and prevent the support body 20 from being cracked or even broken due to excessive stress.

[0064] For example, the support body 20 is a rectangular block, and the bottom surface of the support body 20 for bonding with the toe nail to be corrected can also be a flat surface or an inner concave arc surface, which can be selected flexibly according to needs. Alternatively, the support body 20 can also be a cylindrical body or a circular truncated body, or other applicable configurations, which will not be described here.

[0065] In the present application, the first part 13 and the second part 14 can be a rectangular strip structure, or can be a silk, a rod, a bar or other any applicable configuration, which can be flexibly selected according to actual needs.

[0066] Further, in order to more conveniently install and fix the toe nail corrector 100 on the toe nail to be corrected, in an optional embodiment, the toe nail corrector 100 further comprises a first mounting body 30, which is arranged at the first end of the length direction of the corrector main body 10, and the first mounting body 30 has a first adhesive part 31 for bonding with the toe nail to be corrected.

[0067] Alternatively, in another optional embodiment, the toe nail corrector 100 further comprises a second mounting body 40, which is arranged at the second end of the length direction of the corrector main body 10, and the second mounting body 40 has a second adhesive part 41 for bonding with the toe nail to be corrected.

[0068] Please continue to refer to Figures 1 to 13 Alternatively, in yet another optional embodiment, the toe nail corrector 100 further comprises a first mounting body 30 and a second mounting body 40, the first mounting body 30 is arranged at the first end of the length direction of the corrector main body 10, and the second mounting body 40 is arranged at the second end of the length direction of the corrector main body 10, the first mounting body 30 has a first adhesive part 31 for bonding with the toe nail to be corrected, and the second mounting body 40 has a second adhesive part 41 for bonding with the toe nail to be corrected.

[0069] During installation, the first adhesive part 31 of the first mounting body 30 and the second adhesive part 41 of the second mounting body 40 are coated with an adhesive (such as glue), and then the first mounting body 30 and the second mounting body 40 are pressed to the surface of the toe nail, so that the first adhesive part 31 and the second adhesive part 41 can be bonded and fixed with the toe nail, and a larger bonding area is obtained, the installation firmness is improved, and the normal use is not affected due to the excessive rebound force and the disengagement between the toe nail.

[0070] For example, the first mounting body 30 and the second mounting body 40 are both in the shape of a round cake, and the bottom surfaces of the two are formed with an array structure of protrusions, which abut against the surface of the toe nail to play a supporting role.

[0071] Of course, in other optional embodiments, the first mounting body 30 and the second mounting body 40 can also have other shapes and structures, and the bottom surfaces of the two can also have other support and glue hiding structures, which can be flexibly designed according to actual needs.

[0072] Alternatively, in another optional embodiment, the toe nail corrector 100 further comprises an auxiliary mounting body, which is arranged around the outer periphery of the corrector main body 10, and is used to be fixedly bonded with the toe nail to be corrected. That is, the auxiliary mounting body has a ring-shaped bonding surface, which can be bonded and fixed with the toe nail in a ring-shaped surface, and the bonding area is larger, thereby ensuring better installation firmness of the toe nail corrector.

[0073] Please continue to refer to Figure 13 In yet another embodiment, the toe nail corrector 100 further comprises a spring auxiliary member 50, one end of which is connected with the first mounting body 30 and / or the other end of which is connected with the second mounting body 40. When the first part 13 and the second part 14 are reversely bent for installation, the spring auxiliary member 50 is stretched and lengthened, thereby being able to exert an additional spring force on the first mounting body 30 and the second mounting body 40, which is superimposed on the spring force of the first part 13 and the second part 14, so that the spring force acting on the toe nail is larger, thereby obtaining a better toe nail correction effect.

[0074] Alternatively, as an alternative to the above-mentioned embodiment, the toe nail corrector 100 further comprises a spring auxiliary member 50, which is arranged on one side of the concave part 11, and one end of which is connected with one end of the corrector main body 10, and the other end of which is connected with the other end of the corrector main body 10. This embodiment can also obtain substantially the same technical effect as the above-mentioned embodiment, and thus will not be described here.

[0075] Please continue to refer to Figures 1 to 13 In order to facilitate the use of the toe nail corrector 100, the toe nail corrector 100 further comprises a handle 60, which is detachably connected with the first mounting body 30 and / or the second mounting body 40.
