This invention is aimed to solve current screw extraction problem, and empolders structure-changed intramedullary nail to reduce suffering of patients in screw extraction. This wiredrawing intramedullary nail contains: intramedullary nail body, drawn wire and pin hole; its characteristic is that the intramedullary nail body is made of hollow non-corrodible steel; the drawn wire is made of non-corrodible steel and is located in the intramedullary nail body, and its both ends are welded with the inner wall of the nail body ends, accordingly it can guarantee that in screw extraction the broken nail can be extracted from the other osseous side; in both sides of intramedullary nail body there is a pin hole, which is used to insert pin to fix and stabilized the intramedullary nail. This design can largely predigest screw extraction manipulation, ease patients suffering, shorten resume time after screw extraction, thereby benefit more and more patients. |
