Embodiment Construction

[0034] Next, the intervertebral fusion device associated with the present invention will be described in detail with reference to the accompanying drawings.

[0035] figure 1 It is an oblique view of an intervertebral fusion device according to an embodiment of the present invention, figure 2 for figure 1 An exploded oblique view of the intervertebral cage shown. also, image 3 for figure 1 Top view of the intervertebral cage shown.

[0036] Such as Figure 1 to Figure 3 As shown, the intervertebral fusion device (100) for intervertebral insertion of this embodiment includes an intervertebral fusion device main body (110) and a rotating member (120) rotatably connected thereto.

[0037] The intervertebral fusion cage main body (110) forms the appearance of the intervertebral fusion cage (100), specifically, it has a certain thickness for being inserted between vertebrae, that is, it is approximately the thickness of an undamaged intervertebral disc. The intervertebral ...

Abstract

The inventive concept relates to a cage inserted between vertebrae, and more particularly, to a cage inserted between vertebrae, which implements an articulated rotary motion and may be stably inserted between vertebrae. A cage inserted between vertebrae according to the inventive concept includes a cage body inserted between vertebrae, and a rotary member connected to the cage body to be rotatable and fastened to an inner rod of a cage inserting apparatus. The rotary member includes a connector connected to the cage body, and a screw thread extending from an end of the connector to protrude toward an outside of the cage body and screw-fastened to the inner rod.

Description

technical field [0001] The invention relates to an intervertebral fusion device, in particular to an intervertebral fusion device which realizes articulation rotation and can be stably inserted when inserted between vertebrae. Background technique [0002] The intervertebral disc is a disk of cartilage interposed between the vertebrae of the spine. It absorbs the weight and impact of the body between the vertebrae except for a part of the cervical spine, and acts as a buffer to disperse the impact like a spring. At this time, the intervertebral disc serves to keep the spine from detaching, and to prevent spinal nerves from being compressed, the two vertebrae are separated to secure the range of spinal joint space and ensure smooth movement of each vertebra. [0003] The above-mentioned intervertebral disc is composed of annulus fibrosus and nucleus pulposus. The annulus fibrosus regulates the movement of the spine, while the inner nucleus pulposus is composed of 70-80% water...
