The invention provides a vertebral body structure which comprises a first part, a second part and two vertebral plates, wherein the first part is provided with a spinous process; the second part is provided with a medullary cavity; the first end of the first part is connected with the first end of the second part through one of the two vertebral plates; the second end of the first part is connected with the second end of the second part through the other vertebral plate; and a vertebral canal is defined by the first part, the second part and the two vertebral plates. Through the application of the technical scheme of the invention, the vertebral body structure can remain complete soft tissue, generates less injury to a human body, is more beneficial to recovery of the human body, avoids changing the structure and the motion mode of a power device for a cervical vertebra (or a thoracic vertebra and a lumbar vertebra), prevents vertebra curvature loss, even kyphosis, and avoids the condition that the motion amplitude of the vertebra is limited obviously.
Description
Technical field
The present invention relates to artificial prosthesis technical field, in particular to a kind of vertebral body structure.
Background technology
The spinal canal stenosis of corpus vertebrae is a kind of common skeleton abnormal condition, therefore needs manually to expand canalis spinalis.Realize the expansion of canalis spinalis mainly through two kinds of means in prior art.
The first to open seam groove in bilateral vertebral body outer rim, retains a pleurocentrum inner panel as " door-hinge ", cuts off opposite side vertebral body holostrome and form " enabling crack between a door and its frame ", then started to " door-hinge " by vertebral body, complete single open-door action.Again vertebral body supporting titanium plate is placed between the vertebral body after enabling and lateral mass, on vertebral body and lateral mass, inserts hold-down screw respectively, to maintain permanent " enabling ", thus realize the expansion of canalis spinalis.
Another kind is the first half of extracing vertebral body, namely with a part for spinous process, installs artificial spinous process part afterwards, replaces the first half of vertebral body, realizes the expansion of canalis spinalis.
But, the first step of above two kinds of methods appears vertebral body structure, peel off by epicentral soft tissue, extensively must peel off paraspinal muscle, cut off muscle at each attachment point of cervical vertebra and all rears ligament structure, heavy damage vertebral body rear muscle ligament complex.Recovery postcentrum forms cicatrix with muscle and ligament and is connected, and change power set structure, the motor pattern of vertebral body completely, cause cervical vertebra (or thoracic vertebra, lumbar vertebra) curvature loss, even kyphosis deformity, cervical vertebra motion amplitude is obviously limited.
Summary of the invention
Main purpose of the present invention is to provide a kind of vertebral body structure, needs to peel off epicentral soft tissue, to the hurtful problem of archecenra to solve expansion canalis spinalis of the prior art.
