Abstract

The present invention provides a cervical vertebra implant system. The cervical vertebra implant system is used for implantation between a second cervical vertebra and a seventh cervical vertebra of human body, the cervical vertebra implant system comprises a first implant for supporting and fixing an upper human body cervical vertebra, a connection mechanism, and a second implant for connecting and fixing a lower human body cervical vertebra; and the connection mechanism comprises a first connection member and a second connection member slidably cooperated along a predetermined direction, besides, the direction of the first connection member and a second connection member along the and round the predetermined direction is relatively fixed, the first implant is connected with the first connection member, and the second implant is connected with the second connection member. The cervical vertebra implant system has advantages of easy adjustment and stable and reliable support.

Description

technical field [0001] The invention relates to the field of medical equipment, in particular to a cervical spine implant system. Background technique [0002] As a kind of effective vertebral body substitutes, the artificial vertebral body has been widely used clinically, which has brought great convenience to the treatment of spinal tumors, deformities, trauma and other diseases. The artificial vertebral body can not only better restore the physiological structure of the cervical spine As well as restoring the curvature of the cervical spine, it also has a prominent effect on the reconstruction of spinal stability. [0003] With the development of vertebral body reconstruction and fusion technology, artificial vertebral bodies, as a vertebral body substitute, provide doctors and patients with more treatment options. [0004] In the study, it was found that the artificial vertebral body of the prior art has the following disadvantages in the clinical application process: ...
