Description
Technical field
The present invention relates to a kind of medical instrument, especially a kind of lumbar vertebrae interspinal strutting device.
Background technique
Degenerative lumbar will lead to long-term chronic pain in the loins very intractable, that non-operative treatment is invalid, traditional spinal fusion
Art is to treat the chief surgical method of pain in the loins and lumbar instability, pedicle screw fixation operation and bone morphogenetic protein (BMP)
Using the fusion rate that can help to obtain 90% one 100%, but patient symptom does not obtain the improvement of respective degrees；Furthermore screw
It is fixed that there are potential complication such as Adjacent segment degeneration, screw breakage, pseudarthrosis to be formed with spinal fusion.
Therefore, the theory of surgical treatment is just gradually converted on non-fusion technology.Early stage lumber ertebral disc is moved back
Degenerative disease, facet joint are scorching and intervertebral foramina stenosis nerve is handled caused by being reduced due to disc height, and use is non-rigid
The non-fusion technology that fixed mechanics is supported is a kind of effective technological means.This kind of therapeutic modality and total disc replacement
Special effect is played rapidly in new sublevel segmentation surgical operation strategy together, can postpone or avoid lumbar degenerative disease
The final fusion in stage.The non-fused operation, without the fixation of bone, can retain ridge without being implanted into allograph bone or artificial bone
The anatomical structure of column maintains the motility of backbone and restores its stability, to be easy to perform the operation again.
Non-fusion technology is to treat a kind of lumbago caused effective ways with intermittent claudication of lumbar retrogression, advantage
It is: (1) reduces the motion range of buckling and hyperextension in implantation segment sagittal plain；(2) neural root hole and canalis spinalis are significantly increased
Diameter；(3) reduce the internal pressure of implantation segment interverbebral disc when neutral position and hyperextension position；(4) two sides are reduced
The maximum pressure and average pressure of the articular surface contact area of Minor articulus；(5) adjacent segment have no motion range change and
The sign of interverbebral disc acceleration regression；(6) have not seen the variation of angle between operated level centrum, the variation of interverbebral disc rear height and
The variation of interspinal interstice.
Non-fusion technology is needed using being implanted into non-fused spinous process fixation device between the centrum spinous process of two lumbar vertebraes, simultaneously
A degree of mobility is kept between non-fused spinous process fixation device and upper hypocentrum spinous process.Design common at present is whole
Body is H-shaped, by the left and right sides both wings and lie across the supporter between both wings and form, but it is structure as a whole, left and right both wings it
Between distance fix, when operation, can not do further adjusting, postoperative easy displacement and abjection according to the individual instances of patient.
Summary of the invention
That technical problem to be solved by the invention is to provide a kind of surgical procedures is simple, operation wound is small, postoperative centrum is living
Dynamic property is compared with strong, stability is good, is not easy the lumbar vertebrae interspinal strutting device for shifting and deviating from.
Technical solution used by the present invention solves the above problems is: the device includes the left wing being arranged symmetrically and right flank,
It is structurally characterized in that further include connecting column, withstanding tight block and adjusting bolt, is respectively equipped with lateral left through hole in left wing and right flank
With right through hole, connecting column is placed in right through hole, and withstanding tight block is placed in left through hole, adjust bolt be placed in withstanding tight block and with
The tailing screw flight of connecting column connects.
The invention also includes left pin and right pin, the side of the left wing is equipped with a left side that is vertical with left through hole and communicating
Pin hole, left pin are placed in left pin hole；The side of right flank is equipped with right pin hole that is vertical with right through hole and communicating, right pin
Nail is placed in right pin hole.
The tail portion of connecting column of the invention is recessed circular hole, and circular hole extends the inner bolt matched with adjusting bolt
Hole；Withstanding tight block is made of the pedestal and boss of integral structure, and the outer diameter of boss is less than the outer diameter of pedestal, and the end of boss is placed in
In circular hole；The sets of holes matched with adjusting bolt are equipped in withstanding tight block, adjusting bolt is placed in sets of holes and the interior spiral shell with connecting column
Keyhole is threadedly coupled.
Left through hole of the present invention is from the outside of left wing inwardly successively by the first through hole, the second through hole and third
Through hole composition, wherein the internal diameter of the first through hole is greater than the internal diameter of the second through hole, the internal diameter of third through hole is greater than first
The internal diameter of through hole, and the internal diameter of third through hole is greater than the outer diameter of connecting column tail portion；The pedestal of withstanding tight block, which is placed in first, to be run through
In hole, boss is placed in the second through hole；Left pin is in contact with pedestal, and right pin is in contact with connecting column.
Left wing of the present invention and right flank are equipped with the convex thorn of several evaginations in medial surface relative to each other.
The bar portion of connecting column of the present invention is in four prism type, and head is in cone, and the end on its head is arc-shaped.
Compared with the prior art, the present invention has the following beneficial effects: the device includes left wing, right flank and connecting column, a left side
The distance between the wing and right flank can be adjusted by adjusting bolt, to adapt to the individual instances of each patient；Connecting column position
Between upper and lower spinous process, spinous process up and down is used to support and stablized；Convex thorn and upper and lower spinousprocesses contact in left wing and right flank medial surface,
It is used to help the device to be fixed in centrum, is not easy to shift and fall off.Its action principle is to strut fractional load by spinous process-
Device-spinous process is transmitted, and the distracting force which generates is convex after operated level can be made to occur relatively, makes the ligamentum flavum of infolding
It opens to reduce the intrusion to intraspinal tube, the longitudinal distracting force generated between centrum can increase intervertebral bore dia, to mitigate adjacent vertebra
Regression between body；Sagittal plain mobility is bent and stretched before limitation lesion segment centrum, increases the volume of canalis spinalis and the area of neuraforamen,
Mitigate the pressure of interverbebral disc rear, thus alleviate the pain at leg caused by spinal canal stenosis, buttocks, groin and back etc.,
But it will not influence movement and the pressure conduction of operation adjacent segment centrum.The device for spreading is filled in into supraspinal ligament and Huang in art
Between ligament, left and right can prevent from moving forward, and supraspinal ligament can be provided for instrument and be blocked, and prevent it from moving back；It disperses
Interpyramidal pressure makes lumbar vertebrae be in slight buckling position, allows patient to retain a relatively normal position rather than excessive bends
Song, its merging play the role of stable backbone.The wound face of operation can be greatly reduced using the device, simplify operation stream
The stability of journey, postoperative centrum activity is very good, it is not easy to displacement and abjection, while can be effectively improved to neighbouring section load
The influence of the complication such as increase, regression acceleration, provides a kind of effective means for the rehabilitation of centrum.
