Medtronic Mast Quadrant Retractor System

The MAST QUADRANT™ Retractor System from Medtronic Sofamor Danek is a tubular, minimally invasive retractor platform that allows surgeons to dilate soft tissues and maintain access to the spine using various combinations of articulated and distracting blades. It integrates with visualization tools such as microscopes, cameras, and lighting to enhance operative field visibility. The system includes dilators, retractors, light sources, and pedicle access needles, supporting a range of spinal procedures—herniated disc repair, circumferential decompression, spinal fusion, and implant placement—via anterior or posterior approaches in cervical, thoracic, or lumbar regions. Designed for adaptability, it is compatible with neuromonitoring and imaging systems to facilitate reproducible, single- or multi-level fusion surgeries.
