MODES FOR CARRYING OUT THE INVENTION

(9) First Mode of the Invention

(10) The device for correcting ingrowing nails according to the first embodiment as shown in FIGS. 1-4, comprises a base 101 with a first support 102, in which there are mounted two screws 111, 112 for pressing the toe and two hooks 131, 132 which are slidable and pivotable. The hooks 131, 132 are positioned and immobilized in spheroidal joints 133, 134 which are pressed by hook-blocking screws 135, 136. The toe-pressing screws 111, 112 and the hooks 131, 132 are positioned symmetrically with respect to a lever 121 for pressing the nail which is also mounted in the support 102. The nail-pressing lever 121 is positioned pivotably at the axis of the support 102, and the pressing force is regulated by a screw 123 for regulating the pressing of the nail. Moreover, between the nail-pressing screws 111, 112 and the toe there is placed an elastic pad 114. The base 101 further comprises a second support 103 for spatulas, mounted opposite the first support 102. The second support 103 comprises two parts combined by mounting screws 105, between which a spatula 141 is mounted slidably and pivotably. The spatula 141 is immobilized in a spheroidal joint 143 which is tightened by a spatula-blocking screw 145. The handle 146 of the spatula 145 has a coarse surface.

(11) In place of the hooks 131, 132 for lifting the sides of the nail plate there can be used deflecting spatulas for deflecting asides the flesh of the lateral nail folds.

(12) The hooks 131, 132 allow to lift the lateral edges of the nail, which is particularly useful for correcting involuted nails. The spatula 141 allows to lift the front edge of the nail or to form an extension for an inappropriately cut nail, which is particularly effective when correcting a nail ingrowing to the proximal nail fold.

(13) Second Mode of the Invention

(14) A device for correcting ingrowing nails, according to the second embodiment, as shown in FIG. 5, comprises a base 201 with a first support 202 in which there are mounted two toe-pressing screws 211, 212 and two hooks 231, 232 which are slidable and pivotable. The toe-pressing screws 211, 212 and the hooks 231, 232 are positioned symmetrically with respect to a nail-pressing lever 221, which is also mounted in the support 202. A second support 203 for spatulas is mounted opposite the first support 202. In the second support 203 there are mounted nail-lifting spatulas 241, 242 which are mounted slidably and pivotably in spheroidal joints 243, 244 which are tightened by spatula-blocking screws 245, 246. The pressing lever 221 is mounted in the support 202 in a spheroidal joint 222 which is tightened by a lever-pressing screw 233. Soft pads, for example felt circular pads having a diameter of about 2 cm, can be inserted between the toe-pressing screws 211, 212 and the toe, in order to limit the point wise pressure towards the toe.

(15) Along the base 201 there are protrusions 205 compatible with grooves 206 of a plate 204 for placing a foot, and the base comprises an element for blocking the base 201 in the plate 204. The plate 204 has a size of about 20×30 cm and is made of hard plastic.

(16) In place of the hooks 231, 232 for lifting the sides of the nail plate there can be used deflecting spatulas for deflecting asides the flesh of the lateral nail folds.

(17) The nail-manipulation tools are replaceable and can be selected according to the specifics of the nail being corrected. The replaceability of these tools also allows to sterilize the components for each nail to be corrected.

(18) Exemplary embodiments of the nail-manipulation tools are shown in FIGS. 6-9.

(19) The spatulas for lifting the front edge of the nail may have a form 401-403 as shown in FIG. 6. They may have a handle terminated at both ends by an end. One end may be flat. The other ends may have various arched cutouts, to be selected according to the nail being corrected, the ingrowth depth and the shape of the ingrowth.

(20) The deflecting spatulas may have a form 411-412 as shown in FIG. 7. They may have a handle terminated by one flat end and one curved end. These spatulas are used when inflammatory condition occurs at the lateral nail folds. Then, the deflecting spatulas are mounted in the spheroidal joints in place of the hooks. The deflecting spatula is used to deflect the flesh aside and outwards the nail, such as to uncover the lateral edge of the nail. Then, depending on the shape of the missing fragment of the front edge of the nail, a spatula for lifting the front edge of the nail is selected for reconstructing the nail with a hardening material.

(21) The hooks for lifting the nail edges may have a form 421 as shown in FIG. 8. They may have a handle terminated at both ends with hooks of different inclination.

(22) The lever for pressing the middle portion of the nail towards the base may have a shape 431 as shown in FIG. 9, i.e. it may have a handle with ends of different inclination.

(23) Third Mode of the Invention

(24) The device for correcting ingrowing nails according to the third embodiment is shown in FIG. 11. It comprises a cuboid frame with a flat base 301. The frame forms a support 302 made of four vertical bars 351 attached to the base 301, which are joined at the top by two horizontal bars 354 and two top guides 352. A side guide 353 is attached to two neighboring vertical bars 351. A central top guide 355 is mounted to the two top horizontal bars 354. The guides 353, 352 and 355 have openings 360 made therein. In the support 302, in the openings 360 of the top central guide 355 there are mounted toe-immobilizing means 311 and nail-pressing means 321 towards the base. In the openings 360 of the top central guide 355 there is placed a slidable and pivotable spatula 341 for lifting the front edge of the nail. In the top guides 352 there is mounted slidably and pivotably a hook 331 for lifting the lateral edge of the nail. Moreover, in the side guides 353 there are mounded two further means 311 for immobilizing the toe. The positioning of the toe-immobilizing means 311, the spatula 341 and the hook 331 is blocked by blocking pins 370. Along the handle of the lifting spatula 341 there is a row of openings 360.

(25) Features Common to All Modes For Carrying Out the Invention

(26) All the embodiments share the common features such as: means 111, 112; 211, 212; 311 for immobilizing the toe with respect to the base 101; 201; 301 means 121; 221; 321 for pressing the middle portion of the nail towards the base 101; 201; 301, such as a lever 431 slidable and pivotable means 131, 132; 231, 232; 331 for manipulating at the lateral edge of the nail, which may have a form of hooks 421 or deflecting spatulas 411, 412 slidable and pivotable means 141; 241, 242; 341 for manipulating at the front edge of the nail, which may have a form of spatulas 401-403 for lifting the front of the nail
Method For Correction of Ingrowing Nails

(27) The correction of ingrowing nails is carried out as follows. After the toe (or another finger) is positioned in the device, it is immobilized by toe-pressing means 111, 112; 211, 212; 311 and the nail is pressed by the means 121; 221; 321 towards the base. Next, the lateral edge of the nail is manipulated. For example, the lateral edges of an ingrowing nail are lifted by the hooks 131, 132; 231, 232; 331. Alternatively, in case of an inflammatory condition, the flesh along the lateral edges of the nail is deflected aside by deflecting spatulas. Next, by means of one spatula 141; 341 or two spatulas 241, 242 the nail is lifted at its front in order to shape it appropriately. Next, the nail is coated with a hardening material and the material is left to be cured. Preferably, acryl is used as the hardening material, due to its very good adhesion to the nail and high hardness. Acryl is preferably applied as a layer having a thickness of up to 1 mm. Other hardenable materials can be used, such as a hardenable gel. A nail shaped by hooks and spatulas and coated with acryl in the device of the second embodiment of the present invention is shown schematically in FIG. 10. Next, the nail is machined by grinding. The layer of hardenable material keeps the nail in its correct shape and allows its growth without ingrowing. As the nail grows, it can be filed at the front along with the layer of the hardened material. The end portion of the nail, which is free from the hardened layer, is getting appropriately shaped by the front portion which moves forward. After the whole nail grows, when it is properly shortened at the front, the nail usually achieves a correct shape.

(28) In case of an inflammatory condition, the nail shall be first corrected by means of the deflecting spatulas, and after the inflammatory condition is cured, another correction by means of the lifting hooks shall be made to correct an involuted nail.
