Embodiment Construction

[0030] It should be noted that, in the case of no conflict, the embodiments in the present application and the features in the embodiments can be combined with each other. The present invention will be described in detail below with reference to the accompanying drawings and examples.

[0031] According to one aspect of the present invention, a kind of vertebral body structure is provided, such as Figures 1 to 4 As shown, the vertebral body structure includes: a first part 100 with a spinous process, a second part 200 with a medullary cavity, and two lamina, the first end of the first part 100 and the first end of the second part 200 pass through a lamina Connection, the second end of the first part 100 and the second end of the second part 200 connect the first part 100 and the second part 200 through another lamina to form a spinal canal 300 .

[0032] The vertebral body structure of the present invention expands the vertebral canal 300 through a "top-lifting" type spinal ...

Abstract

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 [0001] The invention relates to the technical field of artificial prosthesis, in particular to a vertebral body structure. Background technique [0002] Spinal stenosis of the human vertebral body is a common skeletal abnormality, so artificial enlargement of the spinal canal is required. In the prior art, the enlargement of the spinal canal is mainly realized by two means. [0003] The first is to open bone grooves on the outer edge of the bilateral vertebrae, retain the inner plate of one side of the vertebra as the "door shaft", cut off the whole layer of the other side's vertebral body to form the "door opening gap", and then move the vertebral body toward the "door shaft". Shaft" is set off to complete the single door opening action. Then the vertebral support titanium plate was placed between the vertebral body and the lateral mass after the door was opened, and fixing screws were respectively placed on the vertebral body and the lateral mass to maint...
