High-mechanical-stability nail external-guidance and internal-fixation configuration device

The invention discloses a high-mechanical-stability nail external-guidance and internal-fixation configuration device comprising a guide apparatus, a connecting plate, a connecting screw, an intramedullary nail, a first femoral nail, a second femoral nail, a locking nail, a first femoral nail hole, a second femoral nail hole, a first cylindrical locating pin and a second cylindrical locating pin, wherein the first femoral nail hole and the second femoral nail hole are formed relatively in a triangular manner. The high-mechanical-stability nail external-guidance and internal-fixation configuration device is provided with the first femoral nail hole and the second femoral nail hole for locating, and the two holes are formed relatively in a triangular manner to form a triangular stable structure to imitate physiological and mechanical states and increase the mechanical stability of the whole structure, so that the device is beneficial for natural healing of a fracture site and is improved in accuracy and relatively low in instrument cost.
