Hip fracture steel plate fixing model based on hip triangle mechanics stable form

Abstract

The invention provides a hip fracture steel plate fixing model based on a hip triangular mechanics stable form, and belongs to the technical field of hip fracture fixation. Comprising a steel plate, and a guide component and a pre-tightening component are mounted on the steel plate; a first countersink, a second countersink and a plurality of third countersinks are formed in one side of the steel plate. Based on the hip triangle mechanical stability theory, a triangular stable fixing strategy for treating hip fracture is constructed according to the specific triangular form structure of the hip, and overall reconstruction of the upper side edge, the outer side edge and the inner side edge of the hip structure is achieved. After hip fracture is fixed, the requirement for early landing of a patient can be met. Due to the special structural configuration of the fixing model, stress distribution is more dispersed and uniform, stress concentration is avoided, the mode is matched with the mechanical structure of the hip, the fixing effect of the steel plate is improved, the success probability of hip fracture internal fixation is increased, and effective rehabilitation of a patient is guaranteed. In addition, the head nail and the inner side supporting nail are guided through the guiding component, the operation is simple and convenient, and the operation efficiency of medical staff is effectively improved.

Description

technical field [0001] The invention relates to the technical field of hip fracture fixation, in particular to a hip fracture steel plate fixation model based on a hip triangular mechanically stable form. Background technique [0002] The hip is the part where the trunk and the legs are connected, which enables the trunk and the legs to move forward, backward and sideways, because the hip is the center of a series of body movements. When a fracture occurs, it needs to be fixed with an internal fixation plate. Most of the fixation plates used for hip fractures adopt eccentric fixation. This method fails to adapt to the mechanical structure of the hip, which not only reduces the fixation effect, but also leads to the occurrence of fixation failure, which is manifested as fracture and failure of the internal fixation. It needs to be treated by a second operation, which will adversely affect the patient, significantly increase the treatment cost of the patient, and cause seriou...

Problems solved by technology

[0004] The technical problem to be solved by the present invention is to provide a hip fracture plate fixation model based on the hip triangular mechanical stable form to solve the problem of increasing the installation cost of the existing plate fixation structure. Stability, the designed structure increases the work difficulty of the medical staff, reduces the operation efficiency, and in order to increase the support effect of the support nail on the hip bone, most of the support nails and the steel plate are screwed into the bone at a certain angle. The stability and accuracy often require the use of additional guiding devices for guidance, which further increases the difficulty of the work of medical staff
