Abstract
A kind of titanium net anti-sinking pad, contacts wall including soleplate contact surface, anti-settling stop block with titanium net.Anti-mat entire body is the titanium alloy material identical with titanium net, or is macromolecular material, such as polyether-ether-ketone, carbon fiber etc..Soleplate contact surface is Zoned structure, smooth surface, or coated with porous coating, beneficially Bone Ingrowth.The soleplate contact surface contacted with soleplate under upper vertebral body is for close to planar structure, and the soleplate contact surface that soleplate upper with the next vertebral body contacts is certain inclination angle (has certain angle of inclination with titanium net longitudinal axis, consistent with soleplate inclination angle, be beneficial to attaching).Anti-settling stop block can be square, triangle, trapezoidal etc..Anti-settling stop block is concordant with soleplate contact surface, contacts with titanium net groove, and keeps stable.After implanting, the pressure from soleplate acts on anti-mat, then conducts to titanium net through anti-settling stop block, thus expands the contact area of soleplate and implant, and then realizes preventing titanium heavy target off the net.
Description
Technical field
The invention belongs to the bone surgery surgical medical technique with the apparatus field of clinical medicine, be specifically related to a kind of titanium net and implant hands
The titanium net anti-sinking pad used in art.
Background technology
At present in spinal surgery, Zhui Qian road Subtotal vertebrectomy, titanium net bone-graft fusion and titanium plate internal fixation are
Widely used modus operandi.But, the titanium net used in above-mentioned operation is implanted the hidden danger brought and is the most gradually highlighted, especially titanium
Heavy problem off the net is increasingly paid attention to by spinal surgery doctor.It is reported, the incidence rate of titanium net subsidence problems is up to 30%.
Titanium is off the net heavy can bring serious consequence, including complication such as ligamenta flava gauffer, nerve root canal are narrow, even needs to carry out neck marrow
Secondary pressure etc. with nerve root.Therefore, designing and developing out and prevent titanium off the net heavy, the technical scheme reducing related complication is to have
Necessary.
Summary of the invention
Goal of the invention: the purpose of patent of the present invention is to design a kind of titanium net anti-sinking pad, and its effect is to solve current hands
The titanium heavy various complication caused off the net present in art, as narrow in ligamenta flava gauffer, nerve root canal etc..
Technical scheme:
A kind of titanium net anti-sinking pad, it is characterised in that: described titanium net anti-sinking pad is Zoned structure；Upper surface is soleplate contact
Face；Annulus inwall is that titanium net contacts wall；The anti-settling stop block of circumference uniform distribution is had on described annulus inwall.
Described titanium net anti-sinking pad is the anti-sinking pad that titanium alloy is made.
The anti-sinking pad that described titanium net anti-sinking pad is polyether-ether-ketone or carbon fiber is made.
It is certain angle of inclination that described soleplate contact surface normal contacts wall axis with described titanium net, this angle and the next vertebra
On body, endplate gradient degree matches.
The cross sectional shape of described dust-proof stop block is square, triangle or trapezoidal.
Described soleplate contact surface surface is covered with porous coating.
Described anti-settling stop block top is concordant with soleplate contact surface.
Advantage and effect:
1., to expand implant and soleplate sclerotin contact surface, effectively prevention titanium is off the net heavy, prevents related complication；
2. titanium net anti-sinking pad can merge with soleplate, limits titanium net movable, even if titanium net bone grafting at a specified future date does not merges, it is also possible to prevent
Titanium net shifts.
Accompanying drawing illustrates:
Fig. 1 is top view of the present invention；
Fig. 2 is side view of the present invention；
Fig. 3 is the cross section view of Fig. 2；
Fig. 4 is side view of the present invention (inclination)；
Fig. 5 is the cross section view of Fig. 4.
Figure marks: 1. soleplate contact surface；The most anti-settling stop block；3. titanium net contact wall.
Detailed description of the invention:
As shown in the figure: the present invention is a kind of titanium net anti-sinking pad, and this titanium net anti-sinking pad is Zoned structure；Upper surface is soleplate
Contact surface 1, smooth surface, or coated with porous coating, beneficially Bone Ingrowth；Annulus inwall is that titanium net contacts wall 3, titanium net contact wall 3
Annular surrounds titanium net, and the two fits tightly.The anti-settling stop block 2 that circumference is arranged is had on described annulus inwall.
Anti-mat entire body is the titanium alloy material identical with titanium net, or is macromolecular material, such as polyether-ether-ketone, carbon fiber
Deng.
In operation, two anti-sinking pads are respectively mounted on the soleplate upper with the next vertebral body of soleplate under upper vertebral body, direction phase
Instead.The soleplate contact surface 1 wherein contacted with soleplate under upper vertebral body is for (the most vertical with titanium net longitudinal axis close to planar structure
Directly, it is simple to attach with soleplate), the soleplate contact surface 1 that soleplate upper with the next vertebral body contacts is in certain inclination angle (with titanium net longitudinally
Axis has certain angle of inclination, consistent with soleplate inclination angle, is beneficial to attach).
The cross sectional shape of dust-proof stop block 2 is square, triangle or trapezoidal.Anti-settling stop block 2 is concordant with soleplate contact surface 1, with
Titanium net groove contacts, and keeps stable.After implanting, the pressure from soleplate acts on anti-mat, then conducts through anti-settling stop block 2
To titanium net, thus expand the contact area of soleplate and implant, and then realize preventing titanium heavy target off the net.
The present invention is applicable to the decompression of anterior cervical vertebrae Subtotal vertebrectomy, titanium net is implanted, fusion fixed by titanium plate bolt
(ACCF), to connect soleplate and titanium net, accept stress, prevent titanium net from subsiding and sink to shifting.
The invention is further illustrated by the following examples.
Embodiment 1:
Sterilization paving is single, makees otch, successively enters, and appears vertebral body, and perspective confirms, row Subtotal vertebrectomy reduces pressure, the bone that will cut
Matter is packed into after being trimmed to skeletal grain in titanium net, installs titanium net anti-sinking pad (head end and tail end), keeps sclerotin and soleplate contact surface
Concordant.Implanting titanium net and anti-sinking pad, place titanium plate, screw is fixed and is locked.Flush operation district, places drainage tube, layer-by-layer suture.
Art finishes.
