Problems solved by technology

In order to solve the problem of loosening and falling off of the cervical spine fixation plate, multiple screws are used in the prior art. Specifically, five screws are embedded in the vertebral body to delay the time of screw loosening. However, this is still a temporary solution, not a permanent cure. The loosening is a matter of time. How to prevent such accidents from happening has not yet been found a good solution.

Abstract

The invention relates to a cervical vertebra fixing device with an odontoid process fusing device, which comprises a main body fixing plate; the main body fixing plate is matched with at least two cervical vertebra fixing screws in a locking manner, wherein one side of the main body fixing plate adhered to the cervical vertebra is provided with a horizontal stretching fusing device which is provided with an axial fusing through hole; bone particles are arranged in the axial fusing through hole; and an odontoid process is arranged on at least one of upper and lower surfaces of the fusing device. Compared with the prior art, the stability and the reliability of the cervical vertebra fixing plate are both greatly enhanced, so that the problem of cervical vertebra fixing plate loosening and falling off from the cervical vertebra can be truly completely eradicated.

Description

technical field [0001] The invention relates to the technical field of medical instruments, in particular to a cervical vertebra fixer, specifically a cervical vertebra fixation plate with an odontoid process fusion device. Background technique [0002] In daily life, cases of partial damage to the cervical spine due to tumors, fractures, infections, etc. occur from time to time. When treating these patients, the current method used is to fix a cervical spine fixation plate by embedding vertebral body screws on the upper and lower vertebral bodies at the damaged site to replace the damaged part of the cervical spine, thereby repairing the damaged vertebral body. Because the cervical spine fixation plate is fixed by screwing into the vertebral body itself, since the neck is a part of the human body that often moves, the screw connection will loosen after a long period of movement, which will bring danger to the patient. In mild cases, the cervical spine needs to be re-fixed. ...
