Abstract
The invention relates to a device used for hooking, holding and fixing the spinous process of a vertebrae, which comprises a hook assembly that is provided with a side plate connected with a hook body, a sliding groove and a movable hooking component that is on the same side surface on which the hook body is connected with the side plate. The device is characterized in that: the hook assembly is connected with the movable hooking component in a sliding manner; the movable hooking component approaches the hook body; the device hooks and holds a spinous process of the vertebrae with the hook body, and the movable hooking component is moved to hook and hold another adjacent spinous process of the vertebrae; and moreover, the hook body and the movable hooking component are moved from the hook body to enlarge the relative distance between the two spinous processes of the vertebrae for locking and stabilization.
Description
Technical field
The invention relates to a kind of spinal crest of Rauber hook keeps steady and decides device, be meant a kind of have a hook group and a moving hook spare especially, described hook group is colluded earlier and is held a spinal crest of Rauber, and described moving hook spare colludes and hold another spinous process, and keeps steady and decide device away from enlarging between described spinous process the spinal crest of Rauber hook of position.
Background technology
The operation of traditional vertebral disease, when being urged to spinal nerve and producing pain perception as happening part, the mode of treatment is removed implantation " pedicle nail ", should save between vertebrae and draw back, and enlarges and discharges space, hard pressed neural place; Maybe can remove the intervertebral disc between two vertebral segments, again be encased inside one synthetical " artificial intervertebral disk ", recovering outside intervertebral position and the neuropore space, be exactly must spinous process by the vertebrae at vertebra rear between, cut off the ridge opisthodetic ligament, implant " Co-Flax " opening device for vertebrae thorn of a U type; Or wear from the tough interband of spinous process and to implant " X-stop " device for spreading spinous process of etc.ing, make the neuropore space enlargement of will described two vertebral segments encircling, will suffer oppression produces pain and feels spinal nerve release, elimination patient's pain.
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, just have spinal crest of Rauber hook of the present invention to keep steady and decide device creation invention.
Summary of the invention
