20150366549 | EXPOSURE APPARATUS FOR POSTERIOR SPINAL MINIMALLY INVASIVE SCREW PLACEMENT SURGERY - An exposure apparatus for posterior spinal minimally invasive screw placement surgery includes a transverse process refractor and a facet joint retractor, is provided. The apparatus separates a gap between a multifidus muscle and a longissimus muscle, easily and atraumatically reach a screw placement position on a pedicle, accurately place the retractors, and thereafter locally form a screw placement tunnel space that externally extends 10 to 15 degrees. During a screw placement operation, the distal end of the transverse process refractor can straddle above the transverse process and is antagonistically tractive with the facet joint retractor so as to leave a sufficient space for the screw placement operation and to prompt a needle inlet point and direction for placing a pedicle screw. The distal end of the refractor employs a design of a recessed crescent type, protects local soft tissues during traction, and prevents the tissues from damage. | 12-24-2015 |
