Abstract

The invention discloses an intervertebral securing device and an intervertebral securing system. The intervertebral securing device comprises a securing plate, wherein the securing plate is provided with a first end and a second end, a first through hole is formed in each of the first end and the second end, a straight pedicle screw penetrates through each first through hole, a second through hole is formed in at least one of the first end and the second end, and an oblique vertebral screw penetrates through each second through hole. According to the intervertebral securing device and an intervertebral securing system disclosed by the invention, two neighboring vertebral joints can be effectively connected and secured, the connection is reliable, and the structure is simple.

Description

technical field [0001] The invention belongs to the field of medical devices, and in particular relates to an intervertebral fixation device and an intervertebral fixation system. Background technique [0002] In the existing spinal surgery process, it is often necessary to connect and fix the two vertebral segments by the principle of tension bands, or to place fusion cages between the vertebrae, or to use the two in combination. The existing connection method is unreliable and cannot be integrated, which will easily lead to loosening, displacement and instability between the two connected vertebrae, which will affect the surgical effect. Contents of the invention [0003] The object of the present invention is to overcome the defects of the prior art and provide an intervertebral fixation device and an intervertebral fixation system. The invention can effectively connect and fix two adjacent vertebrae, and has reliable connection and simple structure. [0004] Its tech...
