Description
Technical field
The present invention relates to a kind of universal flexible fastening rod, belong to the human body Insertion technical field of medical apparatus and instruments.
Background technology
At present, spinal fusion techniques is at treatment spinal disease, and especially low back pain and lumbar instability aspect achieve good curative effect, and fusion rate reaches more than 90%.But there are some researches show, its clinical efficacy does not reach expected value; And the possibility of the complication such as Titanic micro-plates and spinal fusion existence acceleration Adjacent segment degeneration, Unstable internal fixation, postoperative pseudoarticulation formation.Given this, spinal column is dynamically fixing is becoming a kind of technology that treatment Degenerative lumbar disease is more popular in recent years.Dynamic internal fixation system be implanted in the prerequisite of not sacrificing spinal column Initial stability under it is dynamically fixed, the postoperative load conduction dispersibling Internal immobilization, avoid stress shielding, the distracting force produced between sour jujube can produce relative rear convex at operated level, make the ligamenta flava of infolding oppositely open to reduce its intrusion to canalis spinalis, increase vertebral canal volume, also can recover disc height, increase the load of the area of canalis spinalis and intervertebral foramina, unloading rear fibrous ring, reduce corresponding sections Minor articulus load.Postoperative patient recovers rapidly, and the remissions such as relapse rate is low, pain are remarkable, can the plurality of advantages such as early ambulation, recovery daily life.But the dynamic inner fixer of existing spinal column remains in many defects, if any holder the activity in a direction (as Coflex can only provide stretching of sagittal plain in the wrong) can only be provided; As poor in spring system holder elastoresistance damping capacity, and cost of manufacture is very high; As cylindrical in flexible rod holder, although the elasticity of material itself can be relied on to carry out faint Universal active, its range of activity is less, only has an appointment about 3 degree, stretch the range of activity such as in the wrong, rotation much smaller than human spine, be difficult to ensure very low complication and good long-term effect.
Summary of the invention
The object of the invention is to, for above-mentioned the deficiencies in the prior art, a kind of mutually perpendicular U-shaped distressed structure, torsion connecting plate and cylinder of adopting is provided to form, by tightening nuts and hold-down screw, cylinder is fixed between pedicle of vertebral arch, vertebral body, sour jujube plate and on other position sclerotin of human body, by the vertical u-shaped rotary moveable providing vertical direction, horizontal U-shaped provides the rotary moveable of horizontal direction, reverses connecting plate and provides torsion movement, has the universal flexible fastening rod of Universal active performance.
The present invention realizes above-mentioned purpose by the following technical solutions:
This universal flexible fastening rod is made up of U-shaped distressed structure, torsion connecting plate, cylinder, it is characterized in that: by least one, a vertical u-shaped and horizontal U-shaped is formed described U-shaped distressed structure, when the both sides of U-shaped distressed structure are connected with torsion connecting plate respectively, the other end reversing connecting plate is connected with cylinder respectively; When the side of U-shaped distressed structure be connected with reverse connecting plate time, the opposite side of U-shaped distressed structure is directly and cylinder connection.
Described U-shaped distressed structure is at least manufactured with one in hold-down bars.
When this universal flexible fastening rod adopts two to use side by side, be connected and fixed by connecting rod.
The present invention's beneficial effect is compared with prior art:
The elasticity that the middle part of this universal flexible fastening rod is realized between vertebra internode or other sclerotin by orthogonal U-shaped distressed structure struts, its vertical u-shaped rotary moveable that vertical direction is provided, horizontal U-shaped provides the rotary moveable of horizontal direction, reverses the torsion movement that connecting plate provides axial-rotation; Have the sufficient universal elasticity activity of energy, postoperative elastoresistance damping capacity is strong, can be fixed on the advantages such as lumbar vertebra, thoracic vertebra, the lesion segment of cervical vertebra and the two ends of fracture dislocation.Solving the various dynamic spinal inside-fixtures that use at present can not preservation spinal sufficient elasticity activity or carry out elastic limit to the activity of all directions in all directions, and the problem that elastoresistance damping capacity is weak; Also the static problem being fixedly unfavorable for union of fracture such as existing intramedullary pin and steel plate is solved.
