Description
Technical field
The utility model is related to a kind of universal flexible rod, belongs to the human body Insertion technical field of medicine equipment.
Background technology
At present, spinal fusion techniques are achieved preferably in treatment spinal disease, especially low back pain and lumbar instability aspect
Curative effect, fusion rate is up to more than 90%.But there are some researches show, its clinical efficacy and not up to desired value；And Titanic micro-plates and
There is the possibility for accelerating the complication such as Adjacent segment degeneration, Unstable internal fixation, the formation of postoperative pseudarthrosis in spinal fusion.In view of
This, is becoming in dynamic fixation treat in recent years a kind of more popular technology of degeneration cervical vertebra/lumbar disease.Fixed system in dynamic
Being implanted in for system do not sacrifice its dynamic is fixed, the postoperative load for dispersibling Internal immobilization on the premise of backbone Initial stability
Conduction, it is to avoid stress shielding, the distracting force produced between spine can produce relative rear convex in operated level, make the ligamentum flavum of infolding anti-
To opening to reduce its intrusion to canalis spinalis, increase vertebral canal volume, can also recover disc height, increase canalis spinalis and intervertebral foramen
The load of area, unloading rear fibrous ring, reduces corresponding sections Minor articulus load.Postoperative patient recovers rapid, and recurrence rate is low, pain
The remissions such as pain significantly, can early ambulation, many advantages, such as recover daily life.But it is fixed in existing backbone dynamic
Device is remained in many defects, if any fixator activity in a direction can only be provided（As Coflex can only provide sagittal plain
Stretch in the wrong）；As spring system elastoresistance damping capacity is poor, its mobility in all directions is the same, and this is with human body not
There are different mobilities incompatible on same direction, and its cost of manufacture is very high；The flexible rod fixator and for example having is in cylinder
Shape or spirality, although the elasticity of material itself can be relied on to carry out faint Universal active, but its scope of activities is less, often only
Have about 3 degree or so, much smaller than human spine stretch it is in the wrong, rotation etc. scope of activities, and its mobility in all directions be it is impartial,
This is not matched that with the physiological activity pattern of human body；A kind of also " universal flexible fastening rod " of applicant's utility model（Patent
Number：ZL 201420723973.3）, the elastic recoil power after its deformation is not good enough, when human spine long-time is in a fixed appearance
During gesture, easily there is elastic extenuation in its elastic part, in addition, there are in a different direction different activities at the position such as human body lumbar vertebrae
Degree, the such as anteflexion mobility of lumbar vertebrae stretch mobility and lateral bending mobility after being significantly greater than, and existing dynamic internal fixation device fails
Fully designing it has in different directions different mobilities, so as to be adapted with the mobility at the position such as human body lumbar vertebrae, or its
Elastic construction rebounds upon deformation power is weak, therefore above-mentioned prior art is difficult to ensure that 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 one kind is using fixed structure and change
Shape structure composition, distressed structure is to reverse the circular configuration or arc knot that fractional open is cased with connecting plate and U-shaped distressed structure
Structure is constituted, and fixed structure is fixed between pedicle of vertebral arch, centrum, spine plate and other portions of human body by tightening nuts and fixing screws
On the sclerotin of position, by U-shaped certain folding and/or rotation, lateral bending activity are provided, then by be cased with U-shaped the circular of fractional open or
Arcuate structure provides further folding and/or rotation, lateral bending activity, reverses connecting plate and provides torsion movement, can be by arranging U
The circular configuration of fractional open or the height of arcuate structure, width, depth are cased with the number or U-shaped distressed structure of deformation structure
The parameters such as degree, thickness designing different mobilities in a different direction, so as to can Universal active again can be with the life of human body
The universal flexible rod that reason activity pattern matches.
The utility model is by the following technical solutions realizing above-mentioned purpose：
