Abstract
The utility model provides a merging type anchoring bone nail which comprises a nail tip, a nail body and a nail cap. The nail body is composed of a central solid body and an external multi-hole material layer. The merging type anchoring bone nail is made of medical materials which can be implanted into a human body. The nail tip is in a cone shape. The large end of the nail tip changes from 1 mm to 30 mm and can adapt to the needs of bone defect with different sizes. The nail body is placed in the middle of the merging type anchoring bone nail. The nail body is composed of the central solid body and the external multi-hole material layer. The external multi-hole material layer is combined with human body bone tissues and enables the bone tissues to grow in. The external multi-hole material layer is combined with an implanted allograft bone or implanted bone grafting particles or implanted bone cement, so that anchoring is firm. The external multi-hole material layer is provided with a hydroxyapatite coating layer, and the bone tissue can be induced to grow in. The nail cap is of a solid structure so that strike force during an operation can be exerted conveniently.
Description
Technical field
This utility model relates to a kind of orthopaedics implant, refers to especially in operation the bone defect is carried out when body bone, allograph bone or bone cement are filled in advance on the 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 that causes owing to a variety of causes such as sclerotin degeneration, bone tumor, joint overhaul technologies in bone surgery, usually the method that adopts is to implant at the damaged serious position of bone from body or allograph bone piece, osseous granules, bone mud, also has direct employing bone cement to carry out occupy-place and fills; Consider implant stable needs at a specified future date, the doctor who has inserts Kirschner wire with the strength support as implant when implantable bone piece, osseous granules, bone mud or bone cement, but because present employed Kirschner wire mostly is smooth surface, exist the risk of finally from implant, deviating from and lose supporting role because of stressed fine motion.
The utility model content
This utility model provide a kind of and bone bed, implantation from body or allograph bone piece, osseous granules, bone mud and bone cement carry out effective early stage stable knot, grappling firm, and can be in following and bone bed, implantation produce the amalgamation grappling nail that bone merges from body or allograph bone.
For achieving the above object, this utility model amalgamation grappling nail 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, this utility model amalgamation grappling nail, 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; The 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 the 3 D stereo grid: cube, polyhedron, diamond, class are bone trabecular irregularly shaped, and the 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 the outside porous material layer lures and draws bone and grow into; The head of a nail is entity, is convenient to implant hit.
The utility model has the advantages that:
1, this utility model amalgamation grappling nail, 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, the easier sclerotin that enters under identical active force.
2, this utility model amalgamation grappling nail, the 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 the 3 D stereo grid: cube, polyhedron, diamond, class are bone trabecular irregularly shaped; The porous gap is from 30 μ m～3000 μ m; Porous material layer near head can with human body not the defective bone tissue contact, osseous tissue can be grown in the porous material layer, porous material layer can embed mutually with homogeneous allogenic bone, bone grafting granule or bone cement again, grappling is firm; But spraying hydroxyapatite coating on the outside porous material layer induces bone to grow into.
3, this practical amalgamation grappling nail, afterbody is the head of a nail, and head of a nail cross section can be circle with the rivet nut change of shape, and ellipse is square, triangle, polygon; The head of a nail adopts entity structure, is convenient to implant hit.
4, this utility model amalgamation grappling nail 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.

The specific embodiment
Be described further below in conjunction with the implementation of accompanying drawing to this utility model amalgamation grappling nail.
Shown in accompanying drawing 1,2,3, this utility model amalgamation grappling nail, it comprises: nail tip 1, rivet nut 2 and the head of a nail 3, wherein rivet nut 2 is comprised of central entity 4, outside porous material layer 5; Amalgamation grappling nail is made by the medical material of human implantable, and nail tip 1 is taper, and outside diameter changes from 1mm～30mm, can adapt to the different large damaged needs of ossiculum; Be rivet nut 2 in the middle of the amalgamation grappling nail, central entity 4 and outside porous material layer 5 form; Outside porous material layer 5 is combined with body bone tissue, and osseous tissue is grown into, and outside porous material layer 5 is combined with homogeneous allogenic bone, bone grafting granule or the bone cement implanted, makes grappling firm; On the outside porous material layer 5 coating is arranged, can induce osseous tissue to grow into; The head of a nail 3 is entity structure, hits firmly when being convenient to perform the operation.
This utility model amalgamation grappling nail manufacture method: (1) has the amalgamation grappling nail three dimensional design modeling of loose structure in computer; (2) laser selects the metal quick molding methods such as territory sintering or electron beam melting technology directly to generate finished product by metal dust; (3) adopt chemical attack, CVD method to make; (4) adopt machine-tooled method on blank, directly to process.Because described laser selects the methods such as territory sintering or electron beam melting technology, chemical attack, CVD method, machined to be in the industry early known mature technology, no longer does in this article detailed description.
