Anterior cervical steel plate fusion fixing system under endoscope

Abstract

The invention provides an anterior cervical steel plate fusion fixing system under an endoscope. Two steel plate forks are arranged on a fixing steel plate body to form an integrated door-shaped structure; a front end of the steel plate fork is provided with an anti-retreating locking buckle and a blade groove, the angle of an inclined blade of the blade groove is 30 degrees, and the steel plate fork can be more firmly fixed in sclerotin; a perspective window is arranged on the fixed steel plate body, the perspective window is round, and threads are arranged in the perspective window, so the fixation steel plate is convenient to embed under an endoscope; an integrated door-shaped structure is adopted, so the steel plate, the vertebral body and the bone grafting block are firmly connected into a whole, and fusion of bone grafting is facilitated. Due to the screw-free integrated design, other split type steel plate screws are prevented from being disengaged from the steel plate, and thedanger of damaging the esophagus is avoided; the screw is small in size, small in stress shielding rate, small in bone damage to the bone contact interface of the fixed segment screw, relatively highin anti-pull-out capacity and suitable for osteoporosis people.

Description

technical field [0001] The invention relates to an endoscopic fusion and fixation cervical spine plate system, which is used for cervical spine surgery and belongs to the technical field of medical devices. Background technique [0002] At present, there are many types of anterior cervical spine plates for domestic medical devices, including conventional anterior cervical spine plates (Skyline). figure 1 , Anterior cervical sliding plate (Atlantis Translational) see figure 2 , Zero-profile anterior cervical intervertebral fusion cage (Zero-p) see image 3 etc., all of which are designed with separate plates and locking screws, which are prone to problems such as thicker plates and loose screws during use; they increase the fusion rate after cervical spine surgery and reduce the failure rate of internal fixation loosening, but the surgical incision and trauma are more traditional. The operation is large and takes a long time. According to literature statistics, 2% to 67% o...
