Description
Technical field
The present invention relates to the prominent spreading and stabilizing device of a kind of ridge, be meant a kind of position between a spinal crest of Rauber that is implanted to especially, with about two support group this ridge is strutted between prominent, and again with one fixedly lateral plate link the stable ridge spreading and stabilizing device of dashing forward.
Background technology
Traditional vertebral disease operation, when being urged to spinal nerve generation pain perception as happening part, the mode of treatment has implants " pedicle nail and the connecting rod " 10 shown in Fig. 1 a, this pedicle nail is implanted to the pedicle of vertebral arch place of each vertebral segments, and after being connected with this connecting rod, to save between vertebrae and draw back, and make and respectively save the vertebral segments stay bolt and reset; Expansion also discharges space, hard pressed neural place.This mode can solve the ailing problem of vertebra of a part, but operation need open and operate on the place, and wound is big, risk is higher.Or the intervertebral disc between removable two vertebral segments, be encased inside synthetical " artificial intervertebral disk " 11 shown in Fig. 1 b again, be implanted to the intervertebral position of vertebral segments, its upper and lower vertebral segments support height is resetted, to recover intervertebral position and neuropore space.This mode also can solve the vertebral disease of other types, but also need open big wound operation, and the risk of its function difference, operation is also high.Otherwise be between spinous process by the vertebrae at vertebra rear, cut off supraspinal ligament, implant " Co-Flax " spinous process implants 12 of the U type shown in Fig. 1 c.This spinous process implants 12 is implanted by the position of spinal crest of Rauber, the feasible neuropore space enlargement that two vertebral segments are encircled, and the generation pain that will suffer oppression thinks that spinal nerve discharges, and eliminates patient's pain.But this kind medical implant size dimension is fixed, and need select the size of position between the most suitable this spinous process and use, and need cut off during operation and have suitable importance, links each joint of vertebra, and the supraspinal ligament of pulling force is provided.
But emphasize that now operation is wanted simply, face and hemorrhage is operated in minimizing, or reduce infected probability, success effectively again, so as treat the hard pressed pain of spinal nerve in order to aforementioned every method, do not have in vertebral segments under the prerequisite of other significant problem, as if be not inconsistent with the ratio of dealing with problems, and the empty risk the during operation of increase cutter.
Therefore how simple and easy, effectively address the above problem, reduce infection risk, can effectively expand, and the thinking in space, postoperative stability ridge nervi vertebralis hole etc. as far as possible, the prominent spreading and stabilizing device creation of the ridge invention of this case is just arranged.
Summary of the invention
One object of the present invention is to provide a kind of ridge spreading and stabilizing device of dashing forward.
Another object of the present invention is to provide a kind of fixedly lateral plate of two support group and that comprises, and two support group are expansible to strut position between spinal crest of Rauber, this fixedly lateral plate two support group can be linked the prominent spreading and stabilizing device of fixed ridge.
Another purpose of the present invention is to provide a kind of two support group to be connected in series movably with a slide opening with a protrusion slide rail, with the prominent spreading and stabilizing device of ridge of two support group of a screw tightening locking.
