Problems solved by technology

[0002] The proximal femoral intramedullary nail is the most commonly used treatment device for intertrochanteric fractures in clinic. Tension-resistant trabeculae in the two groups, therefore, cannot completely imitate the physiological and mechanical state, the mechanical stability is poor, and it is prone to re-displacement of fractures and failure of internal fixation

Abstract

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.

Description

technical field [0001] The invention relates to the field of orthopedic medical devices, in particular to a highly mechanically stable nail external guide and internal fixation configuration device. Background technique [0002] The proximal femoral intramedullary nail is the most commonly used treatment device for intertrochanteric fractures in clinic. Therefore, the trabecular bone in the two groups of tensile strength cannot completely imitate the physiological and mechanical state, the mechanical stability is poor, and the redisplacement of fractures and the failure of internal fixation are prone to occur. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a highly mechanically stable nail external guide and internal fixation configuration device with simple structure, safe use, high accuracy and low manufacturing cost. [0004] In order to solve the above problems, the present invention adopts the following te...
