Neck Invasive lumbar fusion deviceTechnical field
The present invention relates to a kind of fusion device, especially a kind of neck Invasive lumbar fusion device, for spinal surgery.
Background technology
Intervertebral disc protrusion of cervical vertebra is one of spinal surgery commonly encountered diseases, the effective ways treating intervertebral disc protrusion of cervical vertebraIt is by intervertebral fusion operation, will remove the Intervertebral disk displacement of pathological changes, then put into and intervertebral disc at the vertebral disc portion being removedThe cervical vertebral fusion cage that shape is consistent, makes cervical vertebra reach instant stable, promotes to merge, rebuild and maintain the life of intervertebral height and cervical vertebraReason radian.
The most common cervical vertebral fusion cage needs to coordinate cervical steel plate to use, and during operation, opening is big, complex operation, and due toHaving esophagus and trachea before cervical vertebra, when the steel plate being placed on anterior cervical vertebrae is higher than cervical vertebral surfaces, patient has foreign body sensation, occursThe situation of dysphagia.
Preferably the shape design of Invasive lumbar fusion device should resist fusion device, is beneficial to again merge, and the vertebra of cervical vertebraThere is the inclination of 5 ~ 10 ° surface, and between vertebral body, anterior and posterior height is different, low after front height, if the Invasive lumbar fusion device implanted is difficult to be close toUp and down body of cervical vertebra, is easily caused fusion device and skids off from vertebral body, and once fusion device skids off, and cervical vertebrae physiological radian again hour, willAdjacent phases regression occurs, causes operative failure.Need a kind of intensity and bone close the most clinically and there is good bone conductionProperty and the Invasive lumbar fusion device of osteoinductive.
Summary of the invention
