Publication number: 20130158359Abstract: A three-blade spinal retractor utilizes adjustable and lockable translating arms with angulating blades to provide triangulated medial/lateral and cephalad/caudal tissue retraction for spinal surgeries via the adjustably lockable translating arms. A medial/lateral translating arm with an angularly adjustable retraction blade co-acts and cooperates with angularly adjacent first and second cephalad/caudal translating arms with angularly adjustable retraction blades for tissue retraction and surgical site access. A plate having a medial/lateral adjustment system adjustably holds the medial/lateral translating arm, a first cephalad/caudal adjustment system adjustably holding the first cephalad/caudal translating arm and a second cephalad/caudal adjustment system adjustably holding the second cephalad/caudal translating arm. The translating arms each have a blade holder that provides angular adjustment of the blade.Type: ApplicationFiled: December 19, 2012Publication date: June 20, 2013Inventors: Daniel Predick, Michael S.
