Abstract
The utility model discloses a kind of new astragalus prosthese, including subtalar joint face, articulatio talonavicularis face and tibial astragaloid joint face, the tibial astragaloid joint face is smooth surface；The new astragalus prosthese that the utility model is provided, with biological function, one side tibial astragaloid joint face is smooth surface, is easy to astragalus and tibial prosthesis flexibly movable；Another aspect subtalar joint face and/or articulatio talonavicularis face are loose structure, are easy to prosthese and calcaneum, the rapid fusion growth of nut bone, with great medical value.
Description
Technical field
The utility model is related to a kind of prosthese, is related specifically to a kind of new astragalus prosthese.
Background technology
Collapse resistance talus necrosis is more because body of talus is destroyed by bearing, bone loss is excessive and can not carry out ankle-joint
Replacement operation.Usually using four joint fusions around talectomy and astragalus, the former is easily caused around astragalus unstable, the latter
Ankle moving is easily caused to be limited.How effectively rebuilding range bone and recovering ankle joint function is that orthopedist's processing is collapse resistance
The subject matter of talus necrosis.Prosthetic replacement there is provided good technique means to rebuild range bone and recovering ankle joint function.
Existing astragalus prosthese normally only plays structural support effect, without biological function.How to develop with biological function
Personalized artificial astragalus prosthese is the subject matter that prepared by astragalus prosthese and clinical practice faces.
Utility model content
In view of this, the purpose of this utility model is to provide a kind of new astragalus prosthese, with biological function, one side
It is easy to astragalus and tibial prosthesis flexibly movable；On the other hand grown again beneficial to prosthese interface and the rapid fusion of calcaneum, nut bone, tool
There is great medical value.
A kind of new astragalus prosthese of the present utility model, including subtalar joint face, articulatio talonavicularis face and tibial astragaloid joint face；Institute
Tibial astragaloid joint face is stated for smooth surface.
Further, the subtalar joint face and/or articulatio talonavicularis face are loose structure.
Further, the articulatio talonavicularis face be provided be used to fixing astragalus and nut bone away from boat fixing hole.
Further, the fixing device that the subtalar joint face is used to fix astragalus and calcaneum provided with least one.
Further, the fixing device is fixed column or/and fixing hole.
Further, the fixed column is two, and the fixing hole is one, and three fixing devices are triangularly arranged.
Compared with prior art, the beneficial effect of new astragalus prosthese of the present utility model is：With biological function,
One side tibial astragaloid joint face is smooth surface, the big tibial astragaloid joint face of mobility is kept low friction, anti-degradation characteristic, and extension is false
The service life of body；Another aspect subtalar joint face and/or articulatio talonavicularis face are loose structure, are easy to prosthese and calcaneum, nut bone
Rapid fusion growth, with great medical value.
Brief description of the drawings
The utility model is further described with reference to the accompanying drawings and examples：
Fig. 1 is the first schematic diagram of the new astragalus prosthese of the present invention；
Fig. 2 is the second schematic diagram of the new astragalus prosthese of the present invention；
Fig. 3 is the 3rd schematic diagram of the new astragalus prosthese of the present invention；
Fig. 4 is the 4th schematic diagram of the new astragalus prosthese of the present invention；
The corresponding title of the mark of each in figure is respectively：Subtalar joint face 1, articulatio talonavicularis face 2, fixed column 3, fixing hole
4th, away from boat fixing hole 5, tibial astragaloid joint face 6.
Embodiment
Fig. 1 is the first schematic diagram of the new astragalus prosthese of the present invention, and Fig. 2 is the second of the new astragalus prosthese of the present invention
Schematic diagram, Fig. 3 is the 3rd schematic diagram of the new astragalus prosthese of the present invention, and Fig. 4 is the dead of the new astragalus prosthese of the present invention
Schematic diagram, as shown in the figure：New astragalus prosthese of the present utility model includes subtalar joint face 1, articulatio talonavicularis face 2 and tibial astragaloid joint
Face 6；The tibial astragaloid joint face 6 is smooth surface.
In the present embodiment, the subtalar joint face 1 and/or articulatio talonavicularis face 2 are loose structure, beneficial to subtalar joint face 1
Grown with calcaneum, articulatio talonavicularis face 2 and the rapid fusion of nut bone.
In the present embodiment, the articulatio talonavicularis face 2 be provided be used to fixing astragalus and nut bone away from boat fixing hole 5, design letter
Singly, it is easily achieved.
In the present embodiment, the fixing device that the subtalar joint face 1 is used to fix astragalus and calcaneum provided with least one, just
In the installation and fixation of prosthese.
In the present embodiment, the fixing device be fixed column 3 or/and fixing hole 4, it is simple in construction, easily fabricated.
In the present embodiment, the fixed column 3 is two, and the fixing hole 4 is one, three fixing device cloth triangular in shape
Put, reliable and stable fixed astragalus and calcaneum.
Principle of the present utility model is that new astragalus prosthese has biological function, and one side tibial astragaloid joint face 6 is smooth
Surface, makes the big tibial astragaloid joint face of mobility keep low friction, anti-degradation characteristic, extends the service life of prosthese；On the other hand
Subtalar joint face 1 and/or articulatio talonavicularis face 2 are loose structure, after prosthese is installed, be easy to prosthese and calcaneum, nut bone it is quick
Fusion growth, with great medical value.
Finally illustrate, above example is only unrestricted to illustrate the technical solution of the utility model, although logical
Cross and the utility model is described with reference to preferred embodiment of the present utility model, but one of ordinary skill in the art
It should be appreciated that various changes can be made to it in the form and details, without departing from appended claims institute
The spirit and scope of the present utility model limited.
