The specific embodiment
For further specifying the present invention, cooperate graphic explanation embodiment as follows with preferred embodiment now:
Among Fig. 1, a kind of double elasticity coefficient backbone replacement device 10 of the present invention, it includes a package assembly 20 and an inner piece 30.
This package assembly 20 is one to have most legs 21 and be connected, and surrounds the accommodation space 23 of an opening 22, and these package assembly 20 front ends are a pointed design 24, so that implant vertebral segments 61 on, (as shown in Figure 2) in the middle of the vertebral segments of vertebral segments 62 down.This inner piece 30 is the setting of suitable these package assembly 20 accommodation spaces 23 shapes, and it is placed in the accommodation space 23 of this package assembly 20 by this opening 22.
Be equipped with most perforation 25 on these package assembly 20 legs 21, reach 30 of this inner pieces and convex with most trips 31, described trip 31 can be fashionable in this package assembly 20 and inner piece 30 biphase covers, is sticked in the described perforation 25.
Again on these package assembly 20 legs 21 outer surfaces, convex with most bars point ribs 26, described sharp rib 26 can be sticked on the vertebral segments 61, vertebral segments 62 of this vertebrae tissue (as shown in Figure 3).
Among Fig. 2, behind the package assembly 20 of this double elasticity coefficient backbone replacement device 10 and the inner piece 30 phase fits, and can be in the rear end of this inner piece 30, movable connection one implanting instrument 40 is so that the application of force and control the position of this double elasticity coefficient backbone replacement device 10 in 62 of this vertebral segments 61, vertebral segments.
This implanting instrument 40 has a screw tooth end 41 and a holding end 42, this inner piece has a screw 32 (referring to Fig. 1), these screw tooth end 41 movable this screws 32 that screw togather reach this holding end 42 and can grip the application of force, but make the combination forward-reverse and the left-right rotation direction of this package assembly 20 and this inner piece 30.
And because this inner piece 30 is that a coefficient of elasticity is made between 100 to 250Gpa material, as titanium alloy, this package assembly 20 is that a coefficient of elasticity is made between 2 to 22Gpa material, as PEEK.These inner piece 30 covers are should behind the package assembly 20, in these implanting instrument 40 these vertebrae tissue 61,62 of implantation, reach by these package assembly 20 these vertebrae tissue of contact near the original coefficient of elasticity 12Gpa of this vertebrae tissue.Because the coefficient of elasticity of this package assembly 20, near vertebral segments 61, the vertebral segments 62 original hardness and the coefficient of elasticity of this vertebrae tissue, so after implantation the vertebral segments 61 of described vertebrae tissue, vertebral segments 62 reason hardness great disparity is not excessive, and wear and tear fast.
Among Fig. 3 a and Fig. 3 b, original intervertebral disc atrophy of 62 of the vertebral segments 61 of described vertebrae tissue, vertebral segments is just implanted this double elasticity coefficient backbone replacement device 10 so that recover this original disc height again.
But hardness and coefficient of elasticity because of this package assembly 20, be for the vertebral segments 61, the vertebral segments 62 that cooperate this original vertebrae tissue designed, so these double elasticity coefficient backbone replacement device 10 integral body are these package assembly 20 single materials full during as if implantation, after implantation if need the shift position, or flip angle, direction, understand, and the disruptive doubt in the back of rotation is arranged because of these package assembly 20 hardness deficiencies.
And if when implanting this double elasticity coefficient backbone replacement device 10 whole be these inner piece 30 single materials entirely, have the too fast problem of aforesaid rate of depreciation again.
Therefore, this double elasticity coefficient backbone replacement device 10, skin and the vertebral segments 61 of this vertebrae tissue, the material that vertebral segments 62 contacts, be this package assembly 20 near its original hardness and coefficient, so that the vertebral segments 61, the vertebral segments 62 growth healings that are more suitable for this vertebrae tissue are provided, and do not wear and tear.And when this double elasticity coefficient backbone replacement device 10 after implantation, in the time of should going up vertebral segments 61, following vertebral segments 62 vertebrae tissue with its sharp rib 26 engagings with rotational angle as far as possible, this inner piece 30 that high rigidity is then arranged again, bear the twisting resistance of this implanting instrument 40, avoid this package assembly 20 breakages, and recover the vertebral segments 61 of this vertebrae tissue, original height of vertebral segments 62 intervertebral disc.
