Intended Use

The MAST QUADRANT™ Retractor System is intended to provide surgeons with instruments such as dilators, retractors, light sources and pedicle access needles used to perform a variety of spinal fixation procedures utilizing a minimally invasive approach.

The MAST QUADRANT™ Retractor System is indicated for visualization of the surgical field in any area of the body cut open during a surgical procedure. When used in the cervical, thoracic, or lumbar spine either from an anterior or posterior direction, for example, the MAST QUADRANT™ Retractors and accessories are intended to aid the surgeon's visualization of the surgical area and allow him/her to perform any type of surgical spinal procedure such as herniated disc repair, visualization of the circumferential decompression of the nerve roots, aiding in the search and removal of nucleus material, spinal fusion, or insertion of spinal implants.

Device Description

The MAST QUADRANT™ Retractor System is a tubular-based retraction system, designed to provide surgeons with the freedom to retract tissue through any combination of distracting or articulating the blades. The MAST QUADRANT™ System includes instruments used to access the spine by dilating the overlying tissues, as well serving as a retracting device to maintain the access. The system can be used in conjunction with microscopes, light sources, cameras, or other visualization aids.
