Description
Technical field
The present invention relates to a kind of cervical artificial disc, particularly a kind of cervical artificial disc of plain type.
Background technology
Used in Present clinical, cervical artificial disc design structure is complicated, is nearly all in unilateral consideration terms of mechanics
Problem, it is environment, such as patent cn in the complexity that multiple effect many factors are combined together that human body is ignored in these designs
The disclosed artificial intervertebral disk such as 105105890a, cn 103417313 b, the size of these designs and structure are all relatively more multiple
Miscellaneous, the problems such as may produce abrasion, heat when physical activity, come off, and these design handles and upper soleplate and lower end
On the intermediate member of plate cooperation, surface configuration is designed to convex spherical shape, and this intermediate member is the most critical of mechanical function
Part, when physical activity, from upper sections vertebral body power when acting on intermediate member, the direction of power is all to intermediate member
Center position concentrate, and the effect of human intervertebral disc is by external force dispersion and the effect that eliminates, this life with human intervertebral disc
Reason acts on contrast, and these intermediate member outer surfaces are designed to convex spherical type shape, and this makes intermediate member outer be subject to
To centre concentrate version, in clinical practice, intermediate member may deform because of long-term stress or
Rupture, this brings great risk to patient, so that patient is chronically in potential safety hazard.
Technical scheme
The purpose of the present invention exactly overcome disadvantage mentioned above with not enough, and design that a kind of structure is simple, be suitable for Human Physiology
A kind of cervical artificial disc dissected, easy to use in operation process, and it is suitable for the physiology dissection of multiple human bodies.
The technical scheme is that and be achieved in that: it is made up of upper plate, middle disc, lower plate.Upper plate adopts polyethers
Ether ketone material, may also be employed other materials, and the upper surface of upper plate is designed with positioning bar, the effect of upper positioning bar be make upper plate with
Position after the epimere vertebral body contact of human body is fixed, and the upper surface of upper plate and positioning bar upper surface are designed with positioning tooth, on
Plate upper surface can be with coating, and the purpose of coating is to coat the material good with the human body osteogenesis compatibility in upper surface；Under upper plate
End face is round cavity, and the chamber top surface of round cavity is the spherical design in convex, cylindrical cavity smooth surface, this be in order to
Upper surface cooperation with middle disc；The upper surface of middle disc middle plate mat in the form of annular discs and lower surface can be designed to recessed simultaneously
Shape sphere or upper surface are designed to concave ball surfaces lower surface and are designed to plane, and the spill design of this end face can disperse outer masterpiece
With middle disc adopts ceramic material or other materials；The upper surface of lower soleplate is designed with the enclosure of circle, and the effect of enclosure is
The position making middle disc is in the range of this enclosure, and enclosure inner bottom surface is the spherical design or planar design in convex.Lower end
The lower surface of version is designed with lower positioning bar, and the effect of lower positioning bar is that the position after making lower plate contact with the hypomere vertebral body of human body is solid
Determine, the upper surface of lower plate and positioning bar upper surface are designed with lower positioning tooth, and lower plate adopts polyetheretherketonematerials materials, and it may also be employed
Its material, lower soleplate upper surface can be with coating, and the purpose of coating is to coat the material good with the human body osteogenesis compatibility in lower surface
Material.
During use, the circular intracavity on the lower surface of upper plate is inserted on middle disc top, make the upper surface of middle disc with
Cylindrical cavity top surface forms convex-concave mating spherical surfaces smooth up and down, and according to mechanics principle, this can make corpus vertebrae pass to end
The external force of plate, when reaching spill liner upper surface, through this convex recessed spherical engaging structure, makes external force naturally to four
Week dispersion, simultaneously because matching part be smooth convex-concave spherical design so that upper plate and middle disc and middle disc with
The relative motion of lower plate can complete up and down, around etc. 6 directions are carried out.It is clear that the present invention easily designs solution
Determined the problem of stress, can make again patient's cervical region to up and down, the activity in 6 directions such as around, be also adapted to human body simultaneously
Physiological anatomic architecture, from different size size, the people for different ethnic groups and all ages and classes stage uses.
Brief description
Fig. 1 is the three-dimensional appearance figure of preferred embodiment in the present invention, in figure: upper plate (1), upper positioning bar (1a), upper positioning
Tooth (1b), middle disc (2), lower plate (3), lower positioning bar (3a), lower positioning tooth (3b), enclosure (3c).
Fig. 2 is the assembling section of preferred embodiment in the present invention
Fig. 3 is upper plate (1) upward view of preferred embodiment in the present invention
Fig. 4 be in the present invention preferred embodiment lower plate (3) upward view
Fig. 5 is middle disc (2) profile of preferred embodiment in the present invention
Specific embodiments
Referring to Fig. 1, there is upper positioning bar (1a) upper surface on upper plate (1), and the effect of upper positioning bar (1a) is to make upper plate (1)
Position after being contacted with the epimere vertebral body of human body is fixed, and the upper surface of upper plate (1) and upper positioning bar (1a) upper surface are designed with
The upper positioning tooth (1b) of sharp tooth, on these positioning tooth (1b) be in order to increase upper plate (1) with human vertebra sections relative
Fixing, the lower surface of upper plate (1) has been provided with round cavity, and round cavity top surface is the spherical design in convex, round cavity table
Face is smooth, and upper plate (1) upper surface can be with coating, and the purpose of coating is to coat the material good with the human body osteogenesis compatibility in upper surface
Material.Middle disc (2) is in the form of annular discs, middle disc (2) using pottery or other materials, the upper surface of middle disc (2) and under
End face can be designed to smooth concave ball surfaces simultaneously or upper surface is designed to smooth concave ball surfaces lower surface and is designed to plane.
The upper surface of lower plate (3) is designed with the enclosure (3c) of circle, and the effect of enclosure (3c) is to limit middle disc (2) in certain model
Enclose interior movement, spherical design or the planar design that inner bottom surface is in convex is enclosed in enclosure (3c), the circle inner surface of enclosure (3c) is smooth,
The lower surface of lower plate (3) is designed with lower positioning bar (3a), and the lower surface of lower plate (3) and lower positioning bar (3a) surface are designed with point
