Cervical Hook Vertebral Fusion Cage

Abstract

The invention discloses a cervical vertebra uncovertebral joint fusion cage which comprises uncovertebral joint fusion components and a vertebrae inter elastic supporting body. The cross section of the vertebrae inter elastic supporting body is trapezoidal, and the front end of the vertebrae inter elastic supporting body is a small end. The two uncovertebral joint fusion components are connected to two waist outer side surfaces of the vertebrae inter elastic supporting body respectively and are of a cylindrical mesh structure, and baffles are connected to the side faces, away from the vertebrae inter elastic supporting body, of the uncovertebral joint fusion components. The cervical vertebra uncovertebral joint fusion cage can reduce cost, the fusion time is short, the wearing time of a neck collar is shortened, the comfort level of a patient is improved, an end plate does not need to be ground, the surgical time is shortened, and the sinking risk of prostheses after an operation is reduced.

Description

technical field [0001] The invention relates to the field of medical instruments, in particular to a cervical hook vertebra joint fusion device. Background technique [0002] Cervical fusion has been widely used to treat various cervical diseases for more than half a century. Traditional intervertebral cages are expensive, costing tens of thousands of yuan per piece. Traditional intervertebral discectomy and intervertebral bone graft fusion Emphasis on "vertebral fusion"—bone grows and heals from the center of the upper and lower vertebral bodies. However, due to anatomical and physiological reasons, the distance between the upper and lower vertebral bodies, and possible blood supply and other reasons, the "crawling substitution healing journey" of the bone is long and difficult. Difficult, long healing time (patients need to wear a brace for a long time until fusion), and there is a risk of prosthesis subsidence and displacement after destroying the endplate.
