Abstract
The utility model relates to a prosthetic replacement of bone simulation, in particular to a columnar organization with central bore feeding through in the axial direction. A plurality of concaved and protruding structures of furrows are arranged on the peripheral surface of the columnar organization. On this basis, a plurality of communication holes can be arranged among the furrow structures to communicate with the central bore, and/or the second concaved and protruding structures of furrow can be is arranged in at least one butt end of the above-the columnar organization. This type of prosthetic replacement of bone simulation in this structure can significantly enlarge the contacting surface with the tissue of human body, beneficial to the attachment and growth of human tissue. The prosthetic replacement of bone simulation in this structure can be applied for the renovation of a plurality of bone tissue injury comprising vertebra and long bone.
Description
Technical field
The utility model relates to a kind of implantation that can be used as after human body or the animal bone tissue injury and repair the substitute structure.
Background technology
After the osseous tissue damage of human body or animal body, repairing in the mode of implanting suitable shape substitute, is a kind of therapy rehabilitation means commonly used.The purpose that the osseous tissue substitute is implanted mainly is to provide human body or animal body autologous tissue necessity in the growth repair process to support and attaching structure.Therefore as the structure of repairing substitute, should be able to adapt to as far as possible and satisfy these needs.This class osseous tissue substitute commonly used at present, pay attention to the structure that has similar shapes with the osseous tissue of different parts such as vertebra such as cervical vertebra, thoracic vertebra, lumbar vertebra or long bone of limbs by needing for implant site to be made for respectively, its surface also mostly is and the similar smooth state of actual osseous tissue more.Because the main effect of implanted substitute is for promoting the growth and the reparation of human body autologous tissue, therefore as the planform of bone tissue restoration substitute except that should adapting with the bone structure shape of institute implant site, also should adapt with its significant feature and purpose.
The utility model content
In view of the above, the bionical bone repair that a kind of new structure form is provided of the present utility model makes it can adapt to and bring into play the needs that it promotes that human body adheres to, grows and repairs better.
The bionical bone repair of this utility model, still be the columnar structures of the centre bore that has axial perforation that can make by dense form material that is fit to medical forms such as conventional organic and inorganic or composite and/or porous material etc., this columnar structures can for cylindrical, prismatic, special-shaped column or as the structure of combining form such as " 8 " shape, and the outer peripheral face of its columnar structures is provided with concavo-convex groove structure.Said this concavo-convex groove structure can be in every way or the direction form of extending, wherein more convenient manufacturing and processing be to make the form of said concavo-convex groove structure for extending in the axial direction, and preferably be adopted as some the parallel form that extends axially.After the outer peripheral face of columnar structures is provided with concavo-convex groove structure, can enlarge markedly its surface area, help adhering to and growing of human body autologous tissue, help to merge mutually between dummy and autologous tissue firmly.
Because in actual therapeutic, also often the suitable tissue of self human body is inserted in the centre bore of implanted bone repair, therefore on the basis of said structure, can also in said concavo-convex groove structure, be provided with the access hole that connects with centre bore.These access holes the position is set and/or quantity can be decided as required.The setting of access hole will help growing into, merging between when injected organism tissue in the centre bore and outside organization.
On the said structure basis, further can also be provided with the second concavo-convex groove structure again at least one end of said dummy columnar structures, particularly be provided with this second concavo-convex groove structure in two end faces, also will help increasing and the autologous tissue at its implant site two ends between contact area, help the firm degree that it adheres to, grows and merges.Said this second concavo-convex groove structure that is provided with in the columnar structures end also can be adopted as some the form that be arranged in parallel.Test shows, when two ends of said columnar structures are provided with the second concavo-convex groove structure, the bearing of trend of the second concavo-convex groove structure of its two end faces is with cross one another form, for example one can be for reference embodiment in adopt make the orthogonal form of its bearing of trend for better.
The bionical bone repair that is appreciated that this utility model said structure form can have extensive applicability, applicable to the alternative or reparation to comprising that multiple osseous tissue such as spinal vertebral, long bone damages.
Below, foregoing of the present utility model is described in further detail again by the specific embodiment by the accompanying drawing illustrated embodiment.But this should be interpreted as that the scope of the above-mentioned theme of this utility model only limits to following example.Do not breaking away under the above-mentioned technological thought situation of this utility model, various replacements or change according to ordinary skill knowledge and customary means are made all should be included in the scope of the present utility model.
Description of drawings
Fig. 1 is a kind of version sketch map of the bionical bone repair of this utility model.
Fig. 2 is the end face structure sketch map of Fig. 1.
The specific embodiment
As shown in the figure, this bionical bone repair is the columnar structures 1 that has the centre bore 4 of axial perforation, its outer peripheral face is provided with and extends axially many parallel concavo-convex groove structures 2, in the concavo-convex groove structure 2 and be provided with the access hole 3 that can connect with centre bore 4.Two end faces in columnar structures 1 also is respectively arranged with the second concavo-convex groove structure 5, the second concavo-convex groove structure 5 of each end is some that be arranged in parallel, and the bearing of trend of the second concavo-convex groove structure 5 that is provided with in the two end faces is orthogonal form.
