Intervertebral Fusion Apparatus For Positioning And Combining Vertebrae

Abstract

The present invention provides an intervertebral fusion apparatus for positioning and combining vertebrae, which use a solidifiable material and an intervertebral fusion cage concurrently. By diffusing the solidifiable material from the top or bottom surface of the intervertebral fusion cage, the contact area with vertebrae and hence the stability can be increased. In addition, the intervertebral fusion cage provided by the present invention can further include a wing member connected pivotally on the side and operated concurrently with the solidifiable material to change the shape and thus avoid slipping off the operation opening. By using the intervertebral fusion apparatus, the stability of the intervertebral fusion cage during and after surgeries can be improved effectively. Thereby, the success rate and safety of vertebral fusion surgeries can be increased.

Description

technical field [0001] The invention relates to a spinal operation device, in particular to an intervertebral fusion device positioned and combined with vertebrae. Background technique [0002] As people grow older, the degeneration of hard and soft tissues in the body is inevitable. With the aging of different parts of the body, the degree of impact on daily work and life is also very different. Among them, the aging of the intervertebral disc Lower back pain can be one of the most annoying symptoms. [0003] The intervertebral disc is the connective tissue located between two vertebrae (vertebrae), which acts as a buffer zone between the two vertebrae, slowing down the tension and pressure generated by the movement of the vertebrae, so as to prevent the spine from being subjected to excessive force. injury and pain. The intervertebral disc is generally composed of two parts, the central part is called the nucleus pulposus (nucleus), which mainly provides the ability of t...

AI Technical Summary

Problems solved by technology

[0006] However, the currently used intervertebral fusion device still has some shortcomings that need to be improved urgently.

First of all, the contact area between the current intervertebral fusion cage and the vertebrae is quite small after implantation, which causes the position of the intervertebral fusion cage to deviate during the operation due to the instability of the source of friction, although some The intervertebral fusion cage is designed with serrated top and bottom surfaces to increase the friction between the intervertebral fusion cage and the vertebrae, but the effect is still limited

Furthermore, since the current intervertebral fusion device is implanted in the body from the opening of the intervertebral disc, the height of the intervertebral fusion device is bound to be quite close to the size of the opening. Under good fixation, there is a certain risk that the intervertebral disc will slip out of the surgical opening, which will affect the efficiency of vertebral autogenous restoration in mild cases, and may further compress the nerves and cause unexpected injuries in severe cases
