Description
Technical field
The utility model is related to dynamic fixer between a kind of spine, belongs to the human body Insertion technical field of medicine equipment.
Background technology
At present, spinal fusion techniques achieve preferable curative effect, fusion rate in terms for the treatment of neck pain in the back and neck lumbar instability
Up to more than 90%.But it is existing there are some researches show Titanic micro-plates and spinal fusion are postoperative in the presence of acceleration Adjacent segment degeneration, interior fixation
The possibility of the complication such as failure, the formation of postoperative pseudarthrosis.In consideration of it, backbone is dynamically fixed to turn into treats degeneration in recent years
A kind of hot technology of cervical vertebra/lumbar disease, is also one of following important developing direction of spinal surgery, includes artificial total
Disk displacement, between cervical disc, pedicle dynamic stabilization system, spinous process or between spine plate dynamic stability device and Minor articulus into
Shape dress such as puts at 5 types.The implantation wound of dynamic stability device is minimum wherein between spinous process or between spine plate, security highest, and operation is most
Simply, complication is slight, even if unsuccessfully nor affecting on the treatment of its further surgery, thus quickly grows in recent years.Although spine
Between prominent or between spine plate dynamic stability device be implanted in do not sacrifice it is it is dynamically fixed on the premise of backbone Initial stability, it is postoperative can
Disperse the load conduction of Internal immobilization, it is to avoid the distracting force produced between stress shielding, spine can produce relative in operated level
It is convex afterwards, make the ligamentum flavum of infolding reversely open to reduce its intrusion to canalis spinalis, increase vertebral canal volume, can also recover intervertenral space high
Degree, increases area, the load of unloading rear fibrous ring of canalis spinalis and intervertebral foramen, reduces corresponding sections Minor articulus load；Postoperative patient
Person recovers rapid, and recurrence rate is low, the remission such as pain significantly, can early ambulation many advantages, such as.But existing spinous process
Between or spine plate between dynamic stability device remain in many defects, if any, some prosthese not good with the anatomic form matching of spinous process
Being clashed into spinous process causes abrasion to be reacted, some connections complexity (such as universal dynamic stability device between spine plate), fixator volume also
Cross that wound in substantially art is big, occupy-place is more in postoperative body, installation difficulty (universal dynamic stability device such as between spine), or have it is solid with combination
Fixed fixed for a long time easily lax in the presence of the risk for releasing, or the utilization bundling belt having, prosthese need to press close to endorchis during some installations, increasing
The difficulty of operation technique and the risk of Dural damage are added（As Coflex, its barb are distant to U-shaped bottom, work as U-shaped
When endorchis is not pressed close in bottom, the position that its barb is fixed is then correspondingly away from spinous process root, thus influence fixed effect）,
Some elastic construction screen resiliences are weak, vertical support is poor, postoperative elastoresistance damping force is weak（Such as Coflex）The problems such as, it is difficult to ensure
Very low complication and good long-term effect.
The content of the invention
The purpose of this utility model is, for above-mentioned the deficiencies in the prior art, there is provided between a kind of spine of integral structure
Dynamic fixer；Supraspinal ligament is cut in dynamic fixer art between the spine, fixed part is fixed on spinous process and vertebral plate, elasticity knot
Structure is located at spinous process, the both sides in spine gap.With simple installation in art, the bottom of prosthese does not impose the endorchis, prosthese can enter
The universal elasticity activity of row, elastic construction screen resilience is strong, vertical support is strong and postoperative elastoresistance damping force is strong, fixed reliable, should
Power is disperseed, few to sclerotin excision, can be installed between spinous process root or spinous process and vertebral plate, moreover it is possible to suitable for spinous process too short or spine spacing
Too small case.

The utility model beneficial effect compared with prior art is：
Dynamic fixer realizes between spine that elasticity struts to stretch to bend with backbone and waits work by elastic construction and attachment structure between the spine
It is dynamic, the Dynamic Elastic stabilization of in the wrong, left and right lateral bending and rotation is stretched before and after achievable spinal operation sections, moreover it is possible to realize that operated level is each
Direction is moved and multi-faceted activity comprehensive function forms the dynamic stability that ring turns.With simple structure, stress dispersion, implantation side
Just the features such as, fixation is reliable, the universal elasticity of energy is movable, can be used for excessive lumbosacral angle, spinous process too short or spine spacing too small
The advantages of case.Solve the less disease that cannot be used for spine spacing between the various dynamic spinous process that use at present in inside-fixture art
Example, or prosthese bottom need to press close to endorchis installation, or combining structure has the risk that the prosthetic components such as screw, buckle are released.Together
When also solve the dynamic spinous process that uses at present between or spine-plate between inside-fixture can not fully realize elastic carrier, elasticity between spine
Structural resilience power is weak, elastoresistance damping capacity is not lasting；Born and complex structure, installation operation are complicated, in art and damage big asking
Topic.
