Description
Technical field
The invention belongs to medical instruments field, is related to a kind of adjustment height anchor and goes out formula Invasive lumbar fusion device.
Background technology
Vertebra retrogression pathological changes are clinically common spinal surgery diseases, have a strong impact on minimal invasive treatment and work, operation
Treat the final choice frequently as patient.The modus operandi of spinal treatment is developed to relatively more normal at present by simple lumbar discectomy
The interbody fusion seen, and a series of fusion formula is have developed in being perfectly combined between pursuing centrum, as intertransverse fusion melts
Close art, Minor articulus bone graft fusion, H vertebral plate bone graft fusions etc..
In recent years, to improve the success rate of intervertebral fusion operation, outer fixed dependence is reduced, improves and keep the song of backbone
Degree, Invasive lumbar fusion device arise at the historic moment.From Invasive lumbar fusion device be applied to interbody fusion treatment spinal disease and it is successful since,
Various Invasive lumbar fusion devices are come out one after another, and are widely received by clinic.Invasive lumbar fusion device can effectively maintain anterior spinal stable, retain
Disc height, meet backbone heavy burden and require, be advantageous to the rehabilitation of patient.
But the problem of certain also be present in the Invasive lumbar fusion device technology used now, the intervertebral fusion clinically used at present
Device is mostly fixed structure, it is more difficult to grasps vertebral body reconstruction height, secondary adjustment can not be carried out after implantation；And over time or
The motion of patient, Invasive lumbar fusion device, which can loosen, skids off or is implanted into sinking etc., therefore clinically needs to research and develop after one kind is implanted into surely
It is fixed, the Invasive lumbar fusion device of secondary adjustment can be carried out.
The content of the invention
In order to solve the deficiencies in the prior art, it is an object of the invention to provide a kind of adjustment height anchor to go out formula intervertebral fusion
Device, intervertebral height can be adjusted using the Invasive lumbar fusion device, while prevent the slippage of Invasive lumbar fusion device, reduce pedicle screw
Fixation procedure.
To achieve these goals, the present invention adopts the following technical scheme that：
Go out formula Invasive lumbar fusion device the invention provides a kind of adjustment height anchor, including upper main board 1, lower main board 2, be located at
Bone grafting hole 3 on main board, the upper sleeve pipe 9 on upper main board 1, the setting of casing 10 on lower main board 2, positioned at sleeve pipe
Interior vertebra follows closely 11, tightened up a screw on the upper front side wall of main board 1 hole 51 and lower screw hole 61, is inserted in the hole 51 of tightening up a screw
Oncomelania silk 52 is adjusted, is inserted in the lower screw hole 61 and heightens screw 62, has dentalation 523 on the tune oncomelania silk 52, with vertebra
The occlusion of 11 phases is followed closely, adjusts oncomelania silk 52 to drive the motion of vertebra nail 11 by rotating, adjusts oncomelania silk 52 to follow closely 11 phases with vertebra and be engaged place without sleeve pipe
Barrier, described heighten have ring toothing 623, are engaged with the phase of sawtooth 102 on setting of casing 10 on screw 62, spiral shell is heightened by rotation
Silk 62 drives sleeve pipes movement, by the part of screw is hollow structure 7 when lower main board 2 moves so as to change disc height.
Further, the dentalation of the ring toothing 623 for heightening screw 62 and setting of casing 10 is located at a vertical plane
It is interior.
Further, upper main board 1 and the place plane of lower main board 2 collapse from a lateral opposite side, meet the power of interverbebral disc
Learn construction.
