Abstract

The invention discloses a multi-unit adjustable intelligent interbody fusion cage which comprises a fixing plate, the upper end of the fixing plate is of a square structure, the lower end of the fixing plate is of an arc-shaped structure, a plurality of adjusting units are evenly arranged on the fixing plate, each adjusting unit comprises two adjusting blocks, and the two adjusting blocks are arranged on the two sides of the fixing plate respectively. The adjusting blocks are connected with the fixing plate through the linear moving modules, and the edge formed by the multiple adjusting blocksis attached to the edges of the two sides of the fixing plate to form a whole. The multiple adjustable units are innovatively designed, the adjustable units are perfectly attached to the upper end plate and the lower end plate by adjusting the different telescopic heights of the adjustable units, the curvature of the cervical vertebra operation segment can be better adjusted, the contact area ofthe implant and the end plate is increased, the gap between the implant and the end plate is reduced, and therefore stress concentration is avoided; and complications such as screw loosening, bone resorption around the implant and fusion cage sinking are reduced.

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...
