Abstract

The invention discloses a multi-unit adjustable intelligent intervertebral fusion device, which comprises a fixed plate, the upper end of the fixed plate is a square structure, the lower end of the fixed plate is an arc-shaped structure, and several adjustment units are evenly arranged on the fixed plate , each adjustment unit includes two adjustment blocks, and the two adjustment blocks are set on both sides of the fixed plate; The edges fit together to form a whole. The present invention innovatively designs a plurality of adjustable units, and by adjusting the different telescopic heights of each adjustable unit to make them fit perfectly with the upper and lower endplates, it can better adjust the curvature of the cervical surgery segment and increase the internal The plant-endplate contact area reduces the gap between the implant and the endplate, thereby avoiding stress concentration and reducing complications such as screw loosening, bone resorption around the implant, and cage sinking.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to a multi-unit adjustable intelligent intervertebral fusion device. Background technique [0002] With the acceleration of the aging population in my country and the changes in the production and lifestyle of modern society (mobile phones, TVs, computers, etc.), the incidence of cervical spondylosis is increasing year by year, which brings a heavy social and economic burden. Patients with cervical spondylosis who fail conservative treatment, seriously affect life and work, suffer unbearable pain, and cervical spondylotic myelopathy should actively undergo surgical treatment. Among them, the most classic method of cervical spine surgery is anterior cervical discectomy, decompression and fusion (ACDF). After the intraoperative discectomy and decompression are completed, the cervical curvature of the patient can be adjusted to a better or even normal state by using the cervic...
