Description
Technical field
The present invention relates to dynamic fixer between a kind of spine, belong to the human body Insertion technical field of medical apparatus and instruments.
Background technology
At present, spinal fusion techniques achieves preferable curative effect, fusion rate in terms for the treatment of neck lumbago and neck lumbar instability
Reach more than 90%.But now there are some researches show, Titanic micro-plates and spinal fusion postoperative existence accelerate Adjacent segment degeneration, interior fixing
The possibility of the complication such as failure, postoperative pseudoarticulation formation.In consideration of it, spinal column dynamically fixing becoming 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
Dynamic stability device and Minor articulus become between dish displacement, cervical disc, pedicle dynamic stabilization system, spinous process or between spine plate
5 types such as shape device.Wherein the implantation wound of dynamic stability device is minimum between spinous process or between spine plate, and safety is the highest, and operation is
Simply, complication is slight, even if unsuccessfully nor affecting on the treatment of its further surgery, thus development in recent years is rapid.Although spine
Between Tu or between spine plate dynamic stability device be implanted in do not sacrifice spinal column Initial stability on the premise of it is dynamically fixed, postoperative can
The load conduction of dispersion Internal immobilization, it is to avoid stress shielding, the distracting force produced between spine can produce relative at operated level
The most convex, make the ligamenta flava of infolding reversely open to reduce its intrusion to canalis spinalis, increase vertebral canal volume, also can recover intervertebral space high
Degree, increases canalis spinalis and the area of intervertebral foramina, the load of unloading rear fibrous ring, reduces corresponding sections Minor articulus load；Postoperative patient
Person recovers rapid, and the remissions such as relapse rate is low, pain are notable, can the plurality of advantages such as early ambulation.But existing spinous process
Between or spine plate between dynamic stability device remain in many defects, if any the anatomic form matching with spinous process the best, some prostheses
Clashing into spinous process and cause abrasion reaction, some connections are complicated (such as dynamic stability device universal between spine plate), the holder volume also having
Cross substantially that wound is big in art, occupy-place is many in postoperative body, installation difficulty (such as dynamic stability device universal between spine), or have solid with combination
Calmly there is the risk got loose, or the bundling belt that utilizes having fixes easy relaxing for a long time, during some installations, prosthese need to press close to spinal dura mater, increases
Added the difficulty of operation technique and Dural damage risk (such as Coflex, distant bottom its barb to U-shaped, work as U-shaped
When spinal dura mater is not pressed close in bottom, the position that its barb is fixed is the most correspondingly away from spinous process root, thus affects fixed effect),
The problems such as some elastic construction resilience forces are weak, vertical support is poor, postoperative elastoresistance damping force weak (such as Coflex), it is difficult to ensure
The lowest complication and good long-term effect.
Summary of the invention
It is an object of the invention to, for above-mentioned the deficiencies in the prior art, it is provided that between the spine of a kind of integral structure dynamically
Holder；Dynamic fixer art is cut between this spine supraspinal ligament, fixed part is fixed on spinous process and vertebral plate, elastic construction position
In spinous process, the both sides in spine gap.Having simple installation in art, spinal dura mater is not imposed in the bottom of prosthese, and prosthese can carry out ten thousand
To elastic movable, elastic construction resilience force is strong, vertical support is strong and postoperative elastoresistance damping force is strong, and fixing reliable, stress divides
Dissipate, few to sclerotin excision, can be installed between spinous process root or spinous process and vertebral plate, moreover it is possible to be applicable to spinous process and cross short or spine spacing is too small
Case.
The present invention is to realize above-mentioned purpose by the following technical solutions:
Between this spine, dynamic fixer includes the first fixed part, the second fixed part, attachment structure and elastic construction, the first fixed part and
The bottom of the second fixed part makes one or more barb；It is characterized in that, the first fixed part and the second fixed part are by even
Access node structure and elastic construction are affixed integral；Described elastic construction is made up of one or more connected U-shaped structures, and first is solid
Determining to make on portion and the second fixed part have fixing hole, the inner side of the first fixed part makes pincers tooth a, the inner side system of the second fixed part
Make there is pincers tooth b；Being cased with circle or arcuate structure in described U-shaped structure, the straight plate part of its U-shaped structure divides long 0～15mm, works as U
When the straight plate part of shape structure divides a length of 0, its U-shaped structure is directly substituted by circular configuration or arcuate structure.
Described U-shaped structure is U-shaped opening upwards and/or downward vertical u-shaped, or U-shaped opening inwardly and/or
Outside horizontal U-shaped, or vertical u-shaped and horizontal U-shaped combination, or one or more vertical u-shaped side connection
Concave arc or convex arc is become to form outward opening or the inside horizontal U-shaped of opening.
Described attachment structure is platy structure, column structure, spring structure or helical structure, described attachment structure
A length of 0～8mm, when a length of the 0 of attachment structure, the first fixed part and the second fixed part are directly affixed by elastic construction
Integral.
Each U-shaped height of described U-shaped structure, size, the thickness of plate, plate spacing are consistent or inconsistent, described U
The biside plate face of each U-shaped of shape structure is parallel or not parallel.
The first described fixed part and the thickness of the height of the second fixed part, size or plate, height are consistent or differ
Cause.
The first described fixed part or the thickness of the plate of the different parts of the second fixed part, height are for consistent or differ
Cause.
It it is plane or in cambered surface at the first described fixed part or the second fixed part and spinous process, vertebral plate sclerotin attaching.
The first described fixed part and the second fixed part surface spraying have the material of induction Bone Ingrowth or carry out voided, spiral shell
Stricture of vaginaization processes.
The present invention having the beneficial effects that compared with prior art:
Between this spine dynamic fixer by elastic construction and attachment structure realize elasticity between spine strut with spinal column stretch bend wait activity, can
The Dynamic Elastic stretching in the wrong, left and right lateral bending and rotation before and after realizing spinal operation sections is stable, moreover it is possible to realize operated level all directions
The dynamic stability that motion and multi-faceted the formed ring of activity comprehensive function turn.Have simple in construction, stress dispersion, implant convenient,
Fixation is reliable, can the universal elastic feature such as movable, can be used for that lumbosacral angle is excessive, spinous process crosses short or that spine spacing is too small case
Etc. advantage.Solve the less case that cannot be used for spine spacing between currently used various dynamic spinous process in inside-fixture art,
Or need spinal dura mater to install bottom prosthese, or there is the risk that the prosthetic component such as screw, buckle gets loose in combinative structure.The most also
Solve between currently used dynamic spinous process or between spine-plate, inside-fixture can not fully realize elastic carrier between spine, elastic construction
Resilience power is weak, elastoresistance damping capacity is the most lasting；And structure is complicated, install operation complexity, the problem that in art, negative damage is big.
