Determine screw；7, anti-skid chequer；8, action pane；9, pouring layer；10, layer of silica gel is contacted；11, connecting hole；12, it is adapted to mouth.
Specific embodiment
The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.
As shown in Figure 1-3, a kind of (3D printing) artificial vertebral body system, including connection centrum mechanism and upper and lower two artificial vertebras
Body mechanism；The connection centrum mechanism includes bionical connection centrum 1；Bionical 1 top of connection centrum and bottom end are provided with honeycomb
The articulamentum 2 of shape；Connection layer of silica gel 3 has been poured in articulamentum 2；The artificial vertebral body mechanism on top includes the connection silicon with top
The bionical hemivertebra 4 that glue-line 3 is fixedly connected；Bionical 4 top middle portion of hemivertebra is provided with thread groove 5；5 internal screw thread of thread groove is connected with
Fixing screws 6；6 lateral surface of fixing screws is along the circumferential direction uniformly provided with vertical anti-skid chequer 7；It opens on bionical hemicone right end top
There is action pane 8；Action pane 8 and thread groove 5 are connected；Bionical 4 top of hemivertebra is provided with cellular pouring layer 9；Pouring layer 9
Contact layer of silica gel 10 is inside poured；Contact 10 top middle portion of layer of silica gel is provided with connecting hole 11；Connecting hole 11 and thread groove 5 are connected；
The artificial vertebral body mechanism of lower part and the artificial vertebral body mechanism structure on top are identical and symmetrical above and below；1 inside of bionical connection centrum and
It is honeycomb structure inside bionical hemivertebra 4；Bone meal is filled in bionical connection centrum 1 and in bionical hemivertebra 4；It is fixed
It is cavity structure inside screw 6；6 top of fixing screws is provided with adaptation mouth 12.
Artificial vertebral body is technically being completed based on 3D printing；
And when replacing first centrum being damaged at by artificial vertebral body implantation patient's damaged vertebral body, artificial vertebral body is being planted
It is fashionable, artificial vertebral body is compressed first, so that artificial vertebral body volume is reduced, and the implantation with artificial vertebral body, to artificial
When centrum is squeezed, bionical hemivertebra 4 is squeezed, bionical hemivertebra 4 is to the connection layer of silica gel on bionical connection centrum 1
3 elastic natures for being squeezed, and connecting layer of silica gel 3 make bionical hemivertebra 4 have certain space amount of compression, to reduce people
The volume of work centrum is conveniently placed at impaired centrum；
It after by the centrum of artificial vertebral body implant damage, removes to the extruding force on bionical hemivertebra 4, to make bionical half
Centrum 4 is restored original volume so that contact layer of silica gel 10 occurs with adjacent centrum respectively by the elasticity for connecting layer of silica gel 3
Contact, then the tools such as spanner rotate fixing screws 6 by action pane 8, the anti-skid chequer 7 of 6 outer surface of fixing screws
Keep the rotation of fixing screws 6 more smooth, fixing screws 6 gradually produced from thread groove 5 in rotation and with adjacent centrum
Contact, and be threaded into centrum, and the adaptation mouth 12 on the cavity structure and fixing screws 6 inside fixing screws 6 makes
Intrapyramidal sclerotin enters in fixing screws 6, and sclerotin is grown in fixing screws 6 and makes the fixation of fixing screws 6 more
Add securely, be threaded into centrum after suitable position in fixing screws 6, artificial vertebral body position is fixed, and bionical hemivertebra 4 and imitative
It is fixed by connection layer of silica gel 3 between raw connection centrum 1, to make artificial vertebral body that there is reasonable physiological camber, to make one
Work centrum has certain activity, excessively stiff so as to avoid artificial vertebral body, keeps the use of patient more comfortable；
It, can be solid by that can be determined by image technologies such as X-rays after fixing screws 6 are separately fixed in centrum
Determine the position of screw 6, then punch to adjacent centrum and position is carried out to fixing screws 6 by insertion chock etc.
It is fixed, to keep the fixation of fixing screws 6 stronger；
After bionical hemivertebra 4 is fixed by fixing screws 6, layer of silica gel is contacted with adjacent centrum respectively, silicon
With human body rejection does not occur for the silica gel material of glue-line, and use is safer, and layer of silica gel has certain elasticity, to make
It obtains layer of silica gel and serves as bionical interverbebral disc, for filling the gap between adjacent centrum and artificial vertebral body, reduce bionical hemivertebra 4
With interpyramidal abrasion, centrum is protected, and makes that there is certain activity between centrum and artificial vertebral body, to tie up
The physiological camber between artificial vertebral body and centrum is held, and absorbs the concussion of backbone, use is more comfortable；
Artificial vertebral body is implanted into the patient it is fixed after, the filling in honeycomb porous structure in bionical hemivertebra 4
Bone meal is induced its growth by environmental factor, and the sclerotin grown is filled in inside bionical hemivertebra 4, makes bionical hemivertebra 4 more
Add securely.
