Background technique
Interverbebral disc between the terminal plate of vertebral body of human vertebra is the delicate construction for quite meeting theory of mechanics, its center
Core is a diameter about 1.5cm, and the nucleus pulposus constituted by being full of liquid can bear the pressure of vertebra with deformability
Power, peripheral then be made of the fibrous ring of the crisscross arrangement of multilayer, tough structure can maintain the stability of core, so vertebra
Disk is the natural buffer body of human body, can share the pressure that vertebra is born, avoid spinal cord injury.Human body is often because of carrying heavy goods
Or undue force, long-term fault, the small of the back are caused disc herniation by factors such as gravity impacts, lesser extent person
It will cause fibrous ring to expand but still completely, clinically referred to as disc herniation, degree then cause Anular disruption, vertebra compared with severe one
Core overflows, and is urged to spinal nerve, and clinically referred to as extrusion is de- or prominent.Wherein, more held with the interverbebral disc of older especially
It easily degenerates and causes function abnormal, need to perform the operation.
Wherein, spinal fusion is commonly used for treating the protrusion of the intervertebral disc, the illnesss such as centrum olisthe, it is therefore an objective at two or
Firm bone bridge is created between more vertebraes.When carrying out Intervertebral disc fusion, operation needs to cut with scissors using nucleus pulposus clamp, soleplate
Knife and scraper thoroughly remove the tissue such as nucleus pulposus, fibrous ring and cartilage endplate of bone grafting intervertenral space, appear vertebral bone soleplate, increase
Add bone grafting facial bone contact area, and bone grafting face is made there are enough biomechanical strengths, the intervertebral that then implantation is filled with broken bone melts
Clutch achievees the purpose that bone grafting merges.
General existing expansion instrument only has the function of expansion interbody space, and subsequent soleplate processing needs more
Surgical instrument supports that complex steps expend more operating time, also increase operation risk, and to terminal plate of vertebral body
When reason, different interpyramidal gaps are different, and with the progress that soleplate is handled, intervertenral space can loosen increasing in the process
Greatly, it needs to adjust expansion instrument in time, also affects subsequent terminal plate of vertebral body processing operation to a certain extent.
In view of this, in view of the above problems, it is necessary to which providing a kind of can reach gap between expansion centrum
