Fusion and non-fusion adjustable intelligent spine intervertebral implant

Abstract

The invention discloses a fusion and non-fusion adjustable intelligent spine intervertebral implant. The fusion and non-fusion adjustable intelligent spine intervertebral implant comprises a lower prosthesis and a movable upper prosthesis, wherein the lower prosthesis is used for maintaining the physiological curvature of the cervical vertebra; a support body is fixedly arranged on the lower prosthesis, and the upper prosthesis rotates by taking the support body as a rotation center; a plurality of adjusting pieces used for adjusting the rotating angle of the upper supporting body are arranged on the supporting body and used for maintaining or correcting the curvature of the spine; and driving pieces used for driving the number of the adjusting pieces and limiting the stretching amount of the adjusting pieces are installed in the supporting body and the lower prosthesis. The expansion and contraction amounts of the adjusting pieces are controlled through the driving pieces, so that control over the direction and angle of the upper prosthesis is achieved, the rotation center of the prosthesis can be adjusted, intelligent adjustment conversion between fusion and non-fusion can be achieved, intelligent in-vitro adjustment of the rotation center, and the range of motion and the like can be achieved in the non-fusion technology process, therefore, in-vitro noninvasive personalized adjustment is achieved, and the surgical curative effect is improved.

Description

technical field [0001] The invention belongs to the technical field of intervertebral disc prosthesis, and in particular relates to a fusion and non-fusion adjustable intelligent spinal intervertebral implant. Background technique [0002] In spinal diseases, it is often necessary to rebuild the stability of the spine after the lesion is resected or the spine is unstable. The stability of the spine can usually be divided into spinal fusion surgery and non-fusion surgery. [0003] Since the first report by Hibbs and Albee in 1911, spinal fusion has become a widely used technique in spinal surgery. Spinal fusion is the undisputed "gold standard" in operations on spinal degenerative diseases, instability, and spinal deformities. Spinal fusion refers to taking the diseased vertebra as the center, performing bone grafting from the upper normal vertebra in the lesion area to the lower normal vertebra, so that multiple spinal segments can be bonyly fused to form a mechanical whole,...
