Embodiment Construction

[0031] In order to make the technical problems, technical solutions and advantages to be solved by the present invention clearer, detailed description will be given below with reference to the accompanying drawings and specific embodiments.

[0032] like image 3 , Figure 4 and Figure 5 As shown, the embodiment of the present invention provides a triangular mechanically stable hip fracture fixation device with an adjustable support structure, comprising a steel plate 1, and the steel plate 1 is provided with a guide part, an adjustment part, a limit part and a connecting part. For the anti-loosening part, one side of the steel plate 1 is provided with a support hole 2 .

[0033] The guide member includes two first limit sleeves 3 fixedly mounted on one side of the steel plate 1 symmetrically about the axis of the support hole 2. The two first limit sleeves 3 are axially symmetrical based on the support hole 2, and the two first limit sleeves The sides of the sleeves 3 tha...

Abstract

The invention provides a hip fracture fixing steel plate device with an adjustable supporting structure and a triangular mechanical stable form, and belongs to the technical field of hip fracture fixing. Comprising a steel plate, a guide part, an adjusting part, a limiting part and an anti-loosening part which are connected are arranged on the steel plate, and a supporting hole is formed in one side of the steel plate. The universality of a steel plate fixing model is improved, the difference of the fixing strength of a nail plate system caused by the bone anatomy difference of a patient is avoided, the clinical treatment level of the fracture patient is effectively guaranteed, the installation space of the supporting nails in the hip is effectively increased according to the hip structure, the overall stability effect of the steel plate is improved, and the stability of the whole steel plate is improved. The hip supporting strength of the steel plate fixing model is improved, the strength of the steel plate fixing model is further improved, adverse effects on a patient caused by fixing failure are avoided, and the use risk and the operation frequency of the patient are reduced.

Description

technical field [0001] The invention relates to the technical field of hip fracture fixation, in particular to a hip fracture fixation device with an adjustable support structure in a triangular mechanically stable form. Background technique [0002] The disability rate of hip fracture is as high as 50%. Even after active treatment and rehabilitation training, the mortality rate within 1 year is still 20% to 30%. The surgical treatment of internal fixation is an important treatment method for hip fractures. . [0003] In order to increase the stability of the steel plate and the connection strength of the hip bone, most of the steel plate fixation models used for hip fractures will add support pins, but most of the existing support pins are installed at a vertical angle to the hip bone, which cannot effectively The structure of the bone increases the installation space of the support pin in the hip bone, which reduces the stabilization effect of the support pin, and the exi...
