Patent ID: 11246582

Abstract:
A dual-motion rotation and retraction system for forming a pathway to a patient's intervertebral disc space includes a dilator, retractable dual-blade assembly, and dual-motion retractor. The dilator may feature a narrow rectangular, elliptical, or elongated configuration body for insertion parallel to the fibers of the psoas muscle, including an angle of 0 to 90 degrees to the patient's spine. The dual-blade assembly includes opposing blade subassemblies, each having a blade bordered by adjustable wings, along with built-in lighting and video capabilities. The dual-blade assembly may be passed over the dilator at the insertion orientation. The dual-motion retractor may be disposed about the dual-blade assembly and dilator and employed to both rotate the dual-blade assembly and the dilator 0 to 90 degrees to a final rotated orientation parallel to the intervertebral disc space and to retract the opposing blade subassemblies away from one another to create the surgical pathway. Other embodiments are also disclosed.
