PROBLEM TO BE SOLVED: To provide an ingrown nail correcting device which corrects an ingrown nail by exerting effective and stable correcting force for a long period of time by applying leverage effect and simultaneously corrects deformed parts when at least two deformed parts develop in one nail.SOLUTION: A correcting device body 1 is equipped with an activating piece 3 and a lever piece 4 slanting obliquely upward to the back from the activating piece 3 integrally while having a bending fulcrum part 2 as the center and a plurality of hook-shaped locking parts 5 at a distal end of the activating piece 3. Separately from the correcting device body 1, a correcting member 6 each including a correcting piece 9 at a distal end of a short strip 7 for hooking on the ingrown nail and a locking piece 8 at a proximal end for locking on the locking part 5 is used and is connected to the locking part 5 in accordance with the number of deformed parts of the nail to be corrected, and the ingrown nail A is corrected through the correcting member 6 by the leverage effect of the correcting device body 1.COPYRIGHT: (C)2010,JPO&INPIT【課題】テコの作用により巻き爪を長時間に亘って効果的に且つ安定した矯正力でもって矯正することができると共に、一つの爪で2箇所以上の変形部分が生じている場合でもこれらの部分を同時に矯正することができる巻き爪矯正具を提供する。【解決手段】矯正具主体1は、屈折支点部2を中央にして作動片3と該作動片3から後方に向かって斜め上方に傾斜したレバー片4とを一体に設けていると共に、上記作動片3の先端部に複数のフック形状の係止部5を設けてなる一方、この矯正具主体1とは別に、短い条片7の先端に巻き爪に引っ掛ける矯正片9を、基端に上記係止部5に係止させる係止片8をそれぞれ設けてなる矯正部材6を使用し、この矯正部材6を矯正すべき爪変形部分に応じた数だけ上記係止部5に連結し、矯正具主体1のテコの作用で矯正部材6を介して巻き爪Aを矯正する。【選択図】図3
