Abstract
The utility model discloses a locked intramedullary nail with a distal locating platform. The utility model relates to the locked intramedullary nail, wherein, the distal end of which is provided with the locked intramedullary nail with a locating platform structure. The distal locating platforms can all be arranged in the locked intramedullary nails of the femoral bone, the tibia and the humerus. A structure of the utility model is provided with an intramedullary nail rod, wherein, the near end of which is provided with a lock pin hole, and a distal end is provided with a locking screw hole. The utility model is characterized in that the distal end of the intramedullary nail is provided with the locating platform which can be arranged above or below the distal locking screw hole. When the locked intramedullary nail with the distal locating platform is installed and used, a locating rod for installing the instrument is contacted with the locating platform, and the locating function is stable and reliable. The position of the axle center of the intramedullary nail can be adjusted and controlled according to requirement, and the locked intramedullary nail with the distal locating platform is convenient for the installation of the distal locking screw.
Description
What the interlocking intramedullary nail of this utility model band distal end locating platform related to is the interlocking intramedullary nail that a kind of intra medullary nail far-end has the locating platform structure, belongs to the orthopedic fixation device tool in the medical apparatus and instruments.
At present the shape specification of intramedullary pin has many kinds, but ubiquity far-end location difficulty, and the locating rod end face withstands on very easily slippage on the periphery of intramedullary pin, the shaft core position of intramedullary pin is difficult for adjusting, that have even uncontrollable, far-end two lock screw are difficult to install when causing operation, give rise to trouble.
The purpose of this utility model is to exist weak point that a kind of interlocking intramedullary nail of band distal end locating platform is provided at present interlocking intramedullary nail far-end location, at the interlocking intramedullary nail far-end locating platform is set, the locating rod of installing apparatus withstands on the locating platform, make positioning action reliable and stable, can adjust and control the shaft core position of intramedullary pin on demand, be convenient to the far-end locking screw and install.
The interlocking intramedullary nail of band distal end locating platform takes following mode to realize: the interlocking intramedullary nail of band distal end locating platform has the intramedullary pin bar, be provided with locking nail hole at intramedullary pin bar near-end, far-end has screw hole, be provided with locating platform at intra medullary nail far-end, the far-end locating platform can be located at the top or the bottom of far-end locking screw hole.Femoral interlocking intramedullary nail is owing to the far-end at intramedullary pin is provided with platform, the installing apparatus locating rod is withstood on this locating platform, positioning action is reliable and stable, be convenient to adjust the shaft core position of control intramedullary pin, the far-end locking screw is easy for installation during operation, avoid making operation that difficulty take place because of the position error of apparatus, the interlocking intramedullary nail of band distal end locating platform can comprise intramedullary pins such as femoral interlocking intramedullary nail, tibia interlocking intramedullary nail, humerus interlocking intramedullary nail.
The utility model is described in further detail below with reference to accompanying drawing.
