Abstract
An ingrown fingernail/toenail correction device using a shape memory alloy, includes a first fixing part configured to be fixed to an ingrown fingernail/toenail, a second fixing part configured to be fixed to the ingrown fingernail/toenail and spaced apart from the first fixing part at a predetermined distance, and a correction part inserted into the first fixing part and the second fixing part and made of a shape memory alloy so that when the correction part reaches a preset temperature, a shape of the correction part returns to a preset shape to provide a corrective force to the first fixing part and the second fixing part.
Claims14
An ingrown fingernail/toenail correction device using a shape memory alloy, the ingrown fingernail/toenail correction device comprising:
- a first fixing part configured to be fixed to an ingrown fingernail/toenail;
- a second fixing part configured to be fixed to the ingrown fingernail/toenail and positioned at a side of the first fixing part;
- a third fixing part configured to be fixed to the ingrown fingernail/toenail and positioned between the first fixing part and the second fixing part;
- and
- correction parts configured to be inserted into the first to third fixing parts and made of a shape memory alloy to ensure that when the correction parts reach a preset temperature, shapes of the correction parts return to preset shapes to provide a corrective force to the first to third fixing parts.
An ingrown fingernail/toenail correction device using a shape memory alloy, the ingrown fingernail/toenail correction device comprising:
- a first fixing part configured to be fixed to an ingrown fingernail/toenail;
- a second fixing part configured to be fixed to the ingrown fingernail/toenail and spaced apart from the first fixing part at a predetermined distance;
- and
- a correction part configured to be inserted into the first fixing part and the second fixing part and made of a shape memory alloy to ensure that when the correction part reaches a preset temperature, a shape of the correction part returns to a preset shape to provide a corrective force to the first fixing part and the second fixing part,
- wherein the first fixing part comprises:
- a first attachment portion configured to be attached to one side of an upper surface of the ingrown fingernail/toenail;
- and
- a first central support portion defined at a center of an upper surface of the first attachment portion,
- wherein one side portion of the correction part is fixedly inserted into the first central support portion,
- wherein the first central support portion comprises:
- a first central support member having a roof tile shape protruding upward from the center of the upper surface of the first attachment portion in a direction perpendicular to the first attachment portion;
- and
- a first central support member hole defined between the first attachment portion and the first central support member, and
- wherein a diameter of the first central support member hole is larger than a diameter of the correction part.
