Abstract

The invention discloses a talus prosthesis including a subtalar articular surface and a talonavicular articular surface. The subtalar articular surface and / or the talonavicular articular surface are of porous structures. The talus prosthesis has biological functions, facilitates quick fusion and growth of the prosthesis and a calcaneus and a scaphoid, and thus has great medical value.

Description

A kind of astragalus prosthese
Technical field
The present invention relates to a kind of prosthese, is related specifically to a kind of astragalus prosthese.
Background technology
Collapse resistance talus necrosis are more because body of talus is subject to bearing destruction, 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 It is easily caused ankle moving to be limited.How effectively rebuilding range bone and recovering ankle joint function is that orthopedist's process 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, not with 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.
The content of the invention
In view of this, it is an object of the invention to provide a kind of astragalus prosthese, with biological function, be easy to prosthese interface with The rapid fusion growth of calcaneum, nut bone, with great medical value.
A kind of astragalus prosthese of the present invention, including subtalar joint face and articulatio talonavicularis face；The subtalar joint face and/or away from Navicular articular surface is loose structure.
Further, the subtalar joint face and/or articulatio talonavicularis face are provided with hydroxyapatite coating layer.
Further, the subtalar joint face is provided with least one fixing device, for fixing astragalus and calcaneum.
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.
Further, the articulatio talonavicularis face is provided with away from boat fixing hole, for fixing astragalus and nut bone.
Compared with prior art, the beneficial effect of astragalus prosthese of the invention is：With biological function, it is easy to prosthese Grow with the rapid fusion of calcaneum, nut bone, while prosthese is easily installed fixation, be easy to clinical practice, with great medical science valency Value.
Description of the drawings
With reference to the accompanying drawings and examples the invention will be further described：
Fig. 1 is the first schematic diagram of the astragalus prosthese of the present invention；
Fig. 2 is the second schematic diagram of the astragalus prosthese of the present invention；
Fig. 3 is the 3rd schematic diagram of the astragalus prosthese of the present invention；
The corresponding title of each mark is respectively in figure：Subtalar joint face 1, articulatio talonavicularis face 2, fixed column 3, fixing hole 4th, away from boat fixing hole 5.
Specific embodiment
Fig. 1 is the first schematic diagram of the astragalus prosthese of the present invention, and Fig. 2 is the second schematic diagram of the astragalus prosthese of the present invention, Fig. 3 is the 3rd schematic diagram of the astragalus prosthese of the present invention, as shown in the figure：The astragalus prosthese of the present invention includes the He of subtalar joint face 1 Articulatio talonavicularis face 2；The subtalar joint face 1 and/or articulatio talonavicularis face 2 are loose structure.
In the present embodiment, the subtalar joint face 1 and/or articulatio talonavicularis face 2 are provided with hydroxyapatite coating layer, are more favorable for Subtalar joint face 1 grows with calcaneum, articulatio talonavicularis face 2 and the rapid fusion of nut bone.
In the present embodiment, the subtalar joint face 1 is provided with least one fixing device, for fixing astragalus and calcaneum, just In the installation and fixation of prosthese.
In the present embodiment, the fixing device is fixed column 3 or/and fixing hole 4, simple structure, easily fabricated.
In the present embodiment, the fixed column 3 is two, and the fixing hole 4 is one, three fixing devices cloth triangular in shape Put, can reliable and stable fixed astragalus and calcaneum.
In the present embodiment, the articulatio talonavicularis face 2 is provided with away from boat fixing hole 5, for fixing astragalus and nut bone, design letter Singly, it is easily achieved.
It is loose structure that the principle of the present invention is the subtalar joint face 1 and/or articulatio talonavicularis face 2 of astragalus prosthese, and prosthese exists After operation, subtalar joint face 1 and loose structure present on articulatio talonavicularis face 2 are beneficial to subtalar joint face 1 and calcaneum, away from Zhou Guan The rapid fusion of nodal section 2 and nut bone grows, thus the astragalus prosthese of the present invention to solve traditional prosthesis low with bone interface fusion rate Technical bottleneck, make Postoperative Bone-prosthese interface rapid fusion, postoperative biological function is recovered to greatest extent, with huge doctor Learn value.
Finally illustrate, above example is only unrestricted to illustrate technical scheme, although by ginseng According to the preferred embodiments of the present invention, invention has been described, it should be appreciated by those of ordinary skill in the art that can To it to make various changes in the form and details, without departing from the present invention that appended claims are limited Spirit and scope.
