Abstract
The invention discloses an improved joint prosthesis which comprises a joint rotary portion, a joint supporting portion and a joint connection portion for connecting the joint rotary portion and the joint supporting portion. The joint prosthesis is made of composite materials, a surface layer of the joint prosthesis is bone morphogenetic protein layer with the thickness ranging from 1mu m to 10mu m, and then a baked porcelain layer and a matrix passivation layer are sequentially arranged. The inside of the joint prosthesis is made of titanium materials. Due to the fact that a plurality of composite layers are arranged outside the joint prosthesis, the biocompatibility and an antiwear characteristic of the joint prosthesis are improved. In addition, the improved joint prosthesis has the advantages of being simple in structure and long in service life.
Description
Technical field
The present invention relates to medical devices, be specifically related to a kind of modified model artificial joint.
Background technology
The joint is the hinge of human motion, since wound or pathological changes, possibility " scrapping ", and at this moment the doctor often will " scrap " arthrectomy, change artificial joint.Human synovial is the great-hearted organ of tool, and the artificial joint of changing all is unvital prosthese.
Artificial joint replacement is the articular surface excision with wear-out failure, and as the dress facing, the implantable artificial joint makes it recover normal level and smooth articular surface.Existing joint adopts materials such as comprising alloy, cochrome, pottery and rustless steel to consist of mostly, but in tissue, the long-time delay, easily is corroded or weares and teares.
Summary of the invention
The technical problem to be solved in the present invention provides a kind of modified model artificial joint, utilizes artificial joint
Surface spraying bone morphogenetic protein layer and ceramic layer, biocompatibility and the antiwear characteristic of increase artificial joint, simple in structure, the characteristics that the life-span is long.
For achieving the above object, technical scheme of the present invention is as follows:
A kind of modified model artificial joint comprises the joint rotating part, articular branches support part and the joint connecting portion that connects joint rotating part and articular branches support part, described artificial joint is made of composite, the top layer is the bone morphogenetic protein layer, and the porcelain layer that sets gradually, the substrate passivation layer.
Preferably, described bone morphogenetic protein layer thickness is 1-10 μ m.
Preferably, described artificial joint inside is made of the titanium material.
By technique scheme, the invention has the beneficial effects as follows:
Because the artificial joint outer setting has a plurality of composite beds, increase biocompatibility and the antiwear characteristic of artificial joint, simple in structure, the characteristics that the life-span is long.
Description of drawings
In order to be illustrated more clearly in the embodiment of the invention or technical scheme of the prior art, the below will do to introduce simply to the accompanying drawing of required use in embodiment or the description of the Prior Art, apparently, accompanying drawing in the following describes only is some embodiments of the present invention, for those of ordinary skills, under the prerequisite of not paying creative work, can also obtain according to these accompanying drawings other accompanying drawing.
Fig. 1 is structural representation of the present invention.
The specific embodiment
For technological means, creation characteristic that the present invention is realized, reach purpose and effect is easy to understand, below in conjunction with concrete diagram, further set forth the present invention.
With reference to Fig. 1, a kind of modified model artificial joint, comprise joint rotating part 1, articular branches support part 2 and the joint connecting portion 3 that connects joint rotating part 1 and articular branches support part 2, described artificial joint is made of composite, the top layer is bone morphogenetic protein layer 4, and the porcelain layer that sets gradually, the substrate passivation layer.
Preferably, described bone morphogenetic protein layer 4 thickness are 1-10 μ m.
Preferably, described artificial joint inside is made of titanium material 5.
Because the artificial joint outer setting has a plurality of composite beds, increase biocompatibility and the antiwear characteristic of artificial joint, simple in structure, the characteristics that the life-span is long.
Above demonstration and described ultimate principle of the present invention and principal character and advantage of the present invention.The technical staff of the industry should understand; the present invention is not restricted to the described embodiments; that describes in above-described embodiment and the description just illustrates principle of the present invention; without departing from the spirit and scope of the present invention; the present invention also has various changes and modifications, and these changes and improvements all fall in the claimed scope of the invention.The claimed scope of the present invention is defined by appending claims and equivalent thereof.
