Abstract
This utility model total hip replacement type femoral bone end prosthesis, relate to one sclerotin can be made fully to contact and grow into, far-end prosthese can mate medullary cavity more, fully can adapt to the femur of different shape, make to mate the total hip replacement type femoral bone end prosthesis be achieved on hypogenetic femur accurately.Comprise distal femur prosthese and near end of thighbone prosthese, together with described distal femur prosthese is detachably rotatably installed in described near end of thighbone prosthese, rotation fixture is also provided with between described distal femur prosthese and described near end of thighbone prosthese, the far-end of described distal femur prosthese is provided with bifurcated, and the outer surface of described distal femur prosthese is provided with the groove of longitudinal extension.
Description
Technical field
This utility model relates to a kind of type femoral bone end prosthesis for total hip replacement.
Background technology
In orthopaedics hip replacement, there are the patient of particular patients ' partly and congenital hip dysplasia and the patient with epimere fracture in femur, owing to there is deformity or the fracture of near end of thighbone in this some patients, normal full hip-joint prosthese cannot be adopted to replace, assembly type prosthese can only be adopted, distal femur prosthese and the near end of thighbone prosthese of this prosthese have different models respectively, knockdown installation can be carried out, meet different femoral bone cavitas medullaris forms to greatest extent, but the near-end prosthese of existing assembly type prosthese can not make sclerotin fully contact and grow into, far-end prosthese well can not mate medullary cavity, fully can not adapt to the femur of different shape, be not well positioned to meet treatment needs.
Because above-mentioned defect, the design people, actively in addition research and innovation, to founding a kind of total hip replacement type femoral bone end prosthesis, make it have more value in industry.
Utility model content
For solving the problems of the technologies described above, the purpose of this utility model is to provide one and sclerotin can be made fully to contact and grow into, far-end prosthese can mate medullary cavity more, fully can adapt to the femur of different shape, make to mate the total hip replacement type femoral bone end prosthesis be achieved on hypogenetic femur accurately.
Total hip replacement type femoral bone end prosthesis of the present utility model, comprise distal femur prosthese and near end of thighbone prosthese, together with described distal femur prosthese is detachably rotatably installed in described near end of thighbone prosthese, rotation fixture is also provided with between described distal femur prosthese and described near end of thighbone prosthese, the far-end of described distal femur prosthese is provided with bifurcated, and the outer surface of described distal femur prosthese is provided with the groove of longitudinal extension.
Further, the outer surface of described near end of thighbone prosthese is coated with coating comprehensively.
Further, described distal femur prosthese can relative to described near end of thighbone prosthese 360 ° rotation.
By such scheme, this utility model at least has the following advantages: described near end of thighbone prosthese outer surface is provided with coating and is conducive to the abundant contact of sclerotin and grows into; Described distal femur prosthese can carry out the abundant rotation of 360 ° together with being detachably rotatably installed in described near end of thighbone prosthese, to adjust near end of thighbone prosthese forward leaning angle; The far-end of described distal femur prosthese is provided with bifurcated can make far-end prosthese more mate medullary cavity; The groove that the outer surface of distal femur prosthese is provided with longitudinal extension can play and effectively anti-ly revolve effect, also reduces elastic modelling quantity; Together with described distal femur prosthese is detachably rotatably installed in described near end of thighbone prosthese, the replacing of distal femur prosthese and near end of thighbone prosthese different model can be carried out, the femur of abundant adaptation different shape, makes accurate coupling be achieved on hypogenetic femur.
Above-mentioned explanation is only the general introduction of technical solutions of the utility model, in order to better understand technological means of the present utility model, and can be implemented according to the content of description, coordinates accompanying drawing to be described in detail as follows below with preferred embodiment of the present utility model.
Accompanying drawing explanation
Fig. 1 is the structural representation of this utility model total hip replacement type femoral bone end prosthesis.
Detailed description of the invention
Below in conjunction with drawings and Examples, detailed description of the invention of the present utility model is described in further detail.Following examples for illustration of this utility model, but are not used for limiting scope of the present utility model.
Shown in Figure 1, total hip replacement type femoral bone end prosthesis of the present utility model, comprise distal femur prosthese 1 and near end of thighbone prosthese 2, together with described distal femur prosthese 1 is detachably rotatably installed in described near end of thighbone prosthese 2, rotation fixture is also provided with between described distal femur prosthese and described near end of thighbone prosthese, the far-end of described distal femur prosthese 1 is provided with bifurcated 3, and the outer surface of described distal femur prosthese 1 is provided with the groove 4 of longitudinal extension.Described distal femur prosthese can relative to described near end of thighbone prosthese 360 ° rotation.Described distal femur prosthese can carry out the abundant rotation of 360 ° together with being detachably rotatably installed in described near end of thighbone prosthese, to adjust near end of thighbone prosthese forward leaning angle; The detachable rotation that various structures can be adopted in prior art to realize between described distal femur prosthese and described near end of thighbone prosthese is installed, and does not repeat them here; Relatively fixing by what rotate that fixture can realize between distal femur prosthese and described near end of thighbone prosthese after adjusting rotational angle, screw can be adopted to be used as described rotation fixture; The far-end of described distal femur prosthese is provided with bifurcated 3 can make far-end prosthese more mate medullary cavity; The groove 4 that the outer surface of distal femur prosthese is provided with longitudinal extension can play and effectively anti-ly revolve effect, also reduces elastic modelling quantity; Together with described distal femur prosthese is detachably rotatably installed in described near end of thighbone prosthese, the replacing of distal femur prosthese and near end of thighbone prosthese different model can be carried out, the femur of abundant adaptation different shape, makes accurate coupling be achieved on hypogenetic femur.
The outer surface of described near end of thighbone prosthese 2 is coated with coating comprehensively.The coating that described near end of thighbone prosthese outer surface is provided with is conducive to the abundant contact of sclerotin and grows into.
The above is only preferred implementation of the present utility model; be not limited to this utility model; should be understood that; for those skilled in the art; under the prerequisite not departing from this utility model know-why; can also make some improvement and modification, these improve and modification also should be considered as protection domain of the present utility model.
