Description

Portable ingrown nail correction buckle

Technical field

The present disclosure relates to ingrown nail correction buckles, in particular to a portable ingrown nail correction buckle with precise control and installation.

Background technique

Ingrown nail is a relatively common podiatric disease. If ingrown nails are not corrected, they can easily develop into paronychia. my country has a large population, and the number of people suffering from ingrown nails is huge. There is a large demand for ingrown nail correction products in my country. However, the design and structure of the existing orthodontic devices are unreasonable, resulting in poor practicability, and the complex structure makes it difficult to change the design into Industrialized products. Specifically, the size of the orthosis is limited by the width and length of the toenail, and the thickness of the toenail, the degree of curvature, the difference in shape, the depth of the edge of the toenail into the nail groove and other actual differences, the existing products and technical solutions are It is difficult to adapt to the complex toenail characteristics during the actual installation and wearing process, and it is difficult to realize the original intention and use effect of the technical solution and product structure design. The industrial applicability is very poor; the design is limited by the size of the workpiece, and the handwork cannot be completed well. Installation and adjustment; more complicated structural design is difficult and costly in actual production; the operation is complicated in actual use, the product is difficult to adapt to various types of ingrown nails, and the reliability is poor; the orthosis fits the toenail during the installation operation On the surface, the operating fingers cannot hold the orthosis up and down, and can only rely on the friction force of the end of the fingers to control the assembly of the orthosis. The operator does not have a reliable and effective grip on the orthosis, and cannot apply the up, down, left, and right sides to the orthosis. The precise force of the direction controls the installation process, and it is difficult to complete the installation or to assemble in place.

Therefore, the present disclosure aims to improve the installation structure and facilitate the installation and use of users, and proposes a portable ingrown nail correction buckle to meet the needs of the market.

technical problem

The present disclosure provides a portable ingrown nail correction buckle. The device has strong practicability and is suitable for patients with ingrown nails of various widths, thicknesses, and different curl shapes; wherein, the first fixed elastic piece and the second fixed elastic piece are designed separately.

Beneficial effect

The beneficial effects of the present disclosure are: strong practicability and convenient for practical use. The thin-line auxiliary installation structure solves the shortcomings of small ingrown nails, large fingers and unstable grasping, and it is difficult to wear and operate flexibly; through the thin-line auxiliary installation structure, wear Pull to the middle from time to time, so that the corrective hook of the ingrown nail correction buckle can be hooked tightly to the edge of the toenail during the installation process. The protruding structure of the locking spring piece and the limiting spring piece cooperate to prevent the fixed spring piece connection from shifting during use; The rear ingrown nail correction buckle fits the toenail better, and it is not easy to get out of the hook in daily life. It has the technical effect of faster, more efficient and stable installation.

Furthermore, the present disclosure also has the following technical effects:

1. Under the premise of meeting the flat characteristics of the orthosis and the requirement of 24-hour wear, simplify the complexity of the mechanical structure of the orthosis, and realize the industrial production of the orthosis; the simple mechanical structure also meets the conditions of product reliability and practicability. And the operability of assembly and installation.

2. The necessary auxiliary installation tools and structural design reduce the structural complexity and volume of the orthotic body fixed on the toenail surface; at the same time, it also makes the assembly and installation process operability and the installation result controllable . The size of the ingrown toenail is limited by the size of the toenail. The workpiece of the ingrown toe is too small and too short. It is difficult for the user to grasp the ingrown toenail with his fingers to push the hook of the corrective hook into the edge of the toenail; because the hook needs to be hooked The edge of the toenail, the edge of the toenail is connected with the nail groove meat, so the actual length of the hook can only be about 1.5mm; in the process of hooking the edge of the toenail and installing the ingrown nail correction buckle hook, slightly moving the hook position or other installation operations It may cause the hook to be unhooked, and the edge of the nail can not be stabilized. In actual use, the thickness, curvature, and edge depth of the toenail of different ingrown patients are different, which increases the difficulty for the user to effectively hook the hook into the edge of the toenail, so it is effective The part of the object is pulled toward the middle of the toenail to receive the force to ensure that the hook always hooks the edge of the toenail during installation.

3. After hooking the corrective hooks of the first and second fixing shrapnel into the edge of the toenail, the middle connecting part needs to be clamped, and the first fixing shrapnel and the second fixing shrapnel are pressed down to fit the surface of the toenail for buckling During operation, because the edge of the toenail is curved or even internally hooked, the hook will be subjected to elastic force like the outside, making the hook very easy to unhook; the thin-line auxiliary installation structure can effectively keep the hook from being laterally affected by the middle of the toenail during the installation of the buckle. To ensure that the hook is always hooked to the edge of the toenail and it is not easy to unhook or only part of the length of the hook is hooked into the edge of the toenail, causing the outer back of the hook to reach the next nail groove, causing pain and wearing comfort during daily use.

4. The thin-line auxiliary installation structure can also pull the right and left side correcting steel sheets for snapping operation. Through thin-line traction, the snapping operation is more flexible, and the process of sawtooth snapping into the card interface will not be blocked by the operating fingers. There is no need for blind clamping, and the operation process is visualized; there is no fine-line auxiliary installation structure. Because the workpiece is too small, the operating finger does not have a reliable and appropriate focus on the workpiece. The correcting steel sheet can only be pushed and buckled by the friction of the fingers. It is difficult to achieve accurate and effective control. The workpiece will be disengaged due to lateral and longitudinal displacement. The workpiece will bounce and lose under the action of elasticity, and there is even the risk of accidentally injuring the operator's eyes and face. In the actual use process, most users cannot complete the wearing work for two or three hours with the assistance of others because the workpiece does not have a proper force control point. Some users who can complete the installation and wearing process also find it difficult to hook the hook completely into the edge of the toenail, causing discomfort such as nail pain during the wearing and correction process.

5. The thin-line auxiliary installation structure can effectively assist the installation and exert force while occupying a very small volume of the ingrown nail orthosis. And the structure is simple and reliable, flexible disassembly and assembly, and strong industrial practicability.
