A tool for corrective treatment of an ingrown toenail with a super elastic wire including a tubular member (1) having a length of about 1-2 cm and being tapered such that a diameter at a root is about 2 mm and a diameter at a tip is about 2 mm. A plurality of holes (4) are formed in the tubular member (1) to be distributed over a whole surface of the tubular member (1). A slit (2) is formed in the tubular member (1) by saw-tooth edges (3) such that the tubular member has a C-shaped cross section. After inserting a side edge (Na) of nail plate (N) is inserted into the tubular member (1) via the slit (2), the tubular member is compressed by a pincher and the saw-tooth edges (3) bite on the nail plate (N) to secure the tubular member to the nail plate (N). One end of a super elastic wire (5) is inserted into one or more suitably selected holes to fix the super elastic wire to the tubular member (1) in an easy, stably and effective manner. An elastic force of the super elastic wire (5) applied to the side edge (Na) of nail plate (N) is not concentrated locally and is distributed substantially over a whole length of the side edge. The inwardly curved side edge of nail plate can be effectively corrected into a flat shape within a short treatment time without causing a serious inflammation and pain. <IMAGE> |
