Description
Technical field
The present invention relates to medical instruments field, be specifically related to the Invasive lumbar fusion device that merges for spinal vertebral.
Background technology
When the intervertebral disc generation pathological changes of vertebra or when downright bad, just need to carry out the vertebral fusion operation, traditional operation plan is: the Intervertebral disk displacement of pathological changes is removed, then at the intervertebral disc position that is removed, put into the Invasive lumbar fusion device consistent with the intervertebral disc shape.The structure of the Invasive lumbar fusion device that uses at present comprises the Invasive lumbar fusion device body.The shortcoming of this Invasive lumbar fusion device is: the hold of Invasive lumbar fusion device and adjacent vertebrae piece is low, poor stability, thereby need to be sidelong and put a block plate at one of Invasive lumbar fusion device, the two ends of steel plate fix by the screw vertebra piece adjacent with Invasive lumbar fusion device respectively.So not only perform the operation loaded down with trivial details, particularly when the intervertebral disc of human cervical spine need to use above-mentioned Invasive lumbar fusion device, due to esophagus, trachea being arranged before cervical vertebra, after anterior cervical vertebrae is placed the steel plate higher than the cervical vertebra surface, not only bad for human body blood, transport, descendant's the foreign body sensation of making to perform the operation is strong, has also increased the incidence rate of the postoperative generation dysphagias of people.
Summary of the invention
The Invasive lumbar fusion device that the purpose of this invention is to provide a kind of zero incisura,, good stability high with the hold of vertebra.
for achieving the above object, the present invention has adopted following technical scheme: described Invasive lumbar fusion device, comprise the Invasive lumbar fusion device body, Invasive lumbar fusion device body upper, lower surface is respectively by the setting that slopes inwardly gradually after forward direction, on the Invasive lumbar fusion device body, offer at least two groups of intervertebral fusion lock holes, every group of intervertebral fusion lock hole is comprised of two screw hole that can connect the Invasive lumbar fusion device body, the entrance point of one of them screw hole in every group of intervertebral fusion lock hole and leading flank and the upper surface that the port of export is separately positioned on the Invasive lumbar fusion device body, the entrance point of another screw hole and the port of export are separately positioned on leading flank and the lower surface of Invasive lumbar fusion device body, and guarantee that the angular range between the horizontal cross-section of the axial line of each screw hole and Invasive lumbar fusion device body is 37 °～43 °, angular range between the vertical cross-section of the axial line of each screw hole and Invasive lumbar fusion device body is 2 °～3 °.
Further, aforesaid Invasive lumbar fusion device, wherein: the angle between the horizontal cross-section of the axial line of each screw hole and Invasive lumbar fusion device body is 40 °, the angle between the vertical cross-section of each screw hole and Invasive lumbar fusion device body is 2.5 °.
Further, aforesaid Invasive lumbar fusion device, wherein: on the upper surface of Invasive lumbar fusion device body and lower surface, be evenly distributed with respectively some teeth.
Enforcement by technique scheme; the invention has the beneficial effects as follows: and the hold between vertebra is high; and only screw commonly used in operation on vertebra need be tightened along the direction of advancing to follow closely of screw hole; just can Invasive lumbar fusion device is mutually firm with the adjacent vertebrae piece, and screw can embed in the Invasive lumbar fusion device body fully, not only easy to operate; and realized zero incisura; after people are performed the operation, can not produce foreign body sensation, reduce the probability of the postoperative generation dysphagias of people, protect human body blood fortune.
