Medtronic 9568013 Mast Quadrant Retractor System w/ Case Neurology Spine Ortho

About this product

Half-tube blades hold open a tubular corridor down to the spine, through muscle that dilators have already spread. A knob on the Medtronic Mast Quadrant base swings the blades apart to 30 mm. The 40 mm and 50 mm slots are empty; left and right blade pairs are present in 60 mm, 70 mm and 80 mm. Each is etched in centimeters, so the 60 mm pair reads 6.
