Abstract

The invention relates to an integration anchoring bone nail which comprises a nail point, a nail body and a nail cap. The nail body is composed of a central solid body and an external cellular material layer. The integration anchoring bone nail is made of medical materials capable of being implanted into the human body, the nail point is in a conical shape, the diameter of the nail point changes from 1mm to 30mm, and thus the integration anchoring bone nail can be adapted to the needs of bone defects of different sizes. The nail body is arranged in the middle of the integration anchoring bone nail, and the nail body is composed of the central solid body and the external cellular material layer. The external cellular material layer is combined with the bone tissue of the human body, the bone tissue grows into the external cellular material layer, and anchoring is made to be firm by combining the external cellular material layer and implanted allograft bone or bone grafting particles or bone cement. The bone tissue can be induced to grow into the external cellular material layer due to the fact that a hydroxyapatite coating is arranged on the external cellular material layer. The nail cap is of a solid structure, and striking force can be conveniently applied in surgeries.

Description

Amalgamation grappling nail
Technical field
The present invention relates to a kind of orthopaedics implant, refer to especially in operation to bone defect carry out autologous bone, allograph bone or bone cement while filling in advance on implantable bone bed in order to allograph bone or bone cement supports and the amalgamation grappling nail of grappling effect.
Background technology
Damaged owing to often running into the bone causing due to a variety of causes such as sclerotin degeneration, bone tumor, joint overhaul technologies in bone surgery, conventionally the method adopting is at the damaged serious position of bone, to implant autologous or allograph bone piece, osseous granules, bone mud, also has direct employing bone cement to carry out occupy-place filling; Consider implant stable needs at a specified future date, some doctors insert the strength support that Kirschner wire is usingd as implant when implantable bone piece, osseous granules, bone mud or bone cement, but because current used Kirschner wire mostly is smooth surface, exist and finally from implant, deviate from and lose the risk of supporting role because of stressed fine motion.
Summary of the invention
Autologous or allograph bone piece, osseous granules, bone mud and the bone cement that the invention provides a kind of and bone bed, implantation carry out effectively early stage stable knot, grappling firm, and can produce with the autologous or allograph bone of bone bed, implantation the amalgamation grappling nail that bone merges following.
For achieving the above object, amalgamation grappling nail of the present invention adopts following design:
Amalgamation grappling nail, it is comprised of rivet nut and ailhead to it is characterized in that this grappling nail; Rivet nut is divided into central entity and outside porous material layer.Medical material by human implantable is made, and comprises medical metal material, medical high polymer organic material and medical ceramic.
Described amalgamation grappling nail is characterized in that, amalgamation grappling nail of the present invention, and its head is nail tip, adopts tapered design, outside diameter changes from 1mm~30mm, to adapt to the damaged needs that vary in size of bone; Centre is rivet nut, its cross sectional shape can be for multiple: circle, ellipse, triangle, polygon, rivet nut is comprised of central entity and outside porous material layer, central entity can provide strength support, outside porous material layer is 3 D stereo grid: cube, polyhedron, diamond, class are bone trabecular irregularly shaped, and porous gap is from 30 μ m~3000 μ m; Porous material layer can be combined with osseous tissue, and bone is grown into, and can embed mutually with homogeneous allogenic bone, bone grafting granule or bone cement again, and grappling is firm; Spraying hydroxyapatite on outside porous material layer, lures and draws bone and grow into; The head of a nail is entity, is convenient to implant hit.
Advantage of the present invention is:
1, amalgamation grappling nail of the present invention, its head is nail tip, adopts tapered design, outside diameter changes from 1mm~30mm, can adapt to the different large damaged needs of ossiculum; Nail tip adopts conical design, and most advanced and sophisticated pressure reaches the highest, more easily enters sclerotin under identical active force.
2, amalgamation grappling nail of the present invention, centre is rivet nut, its cross sectional shape can be for multiple: circle, ellipse, square, triangle, polygon; Rivet nut is comprised of central entity and outside porous material layer; Central entity can provide strength support, and outside porous material layer is 3 D stereo grid: cube, polyhedron, diamond, class are bone trabecular irregularly shaped; Porous gap is from 30 μ m~3000 μ m; Porous material layer near head can with human body not defective bone tissue contact, osseous tissue can be grown in porous material layer, porous material layer can embed mutually with homogeneous allogenic bone, bone grafting granule or bone cement again, grappling is firm; Can spraying hydroxyapatite coating on outside porous material layer, induction bone is grown into.
3, this practical amalgamation grappling nail, afterbody is the head of a nail, and head of a nail cross section, with rivet nut change of shape, can be circle, and ellipse is square, triangle, polygon; The head of a nail adopts entity structure, is convenient to implant hit.
4, amalgamation grappling nail of the present invention adopts the material of medical human implantable to make, and material can, for metal material, the bioceramic of the human implantables such as titanium alloy, tantalum metal, rustless steel, also can be medical macromolecular materials and make.
