摘要： A guiding apparatus for x-ray-free screw placement by a spinal posterior approach, comprising an interspinous spacer, a slide scale (1), and an angle-changing rod. The apparatus is simple to operate, easy to grasp, and well accepted by physicians. A reliable effect is provided in screw placement. Significantly reduced X-ray exposure is allowed for patients and medical staff. In a small-incision minimally invasive screw placement operation, even without exposing the spinal ligament, a small spike-like protrusion of a base (2) of the interspinous spacer can ensure accurate interspinous positioning across the skin. This is applicable for both minimally invasive and incision surgeries and has a wide range of uses.

摘要： 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.

摘要： An exposure apparatus for a paraspinal muscle clearance approach with a posterior spinal small incision includes a spinous process side vertebral plate retractor and a cooperating vertebral arch outer side retractor is provided. The apparatus can be used to separate a clearance between a multifidus muscle and a longissimus muscle under direct view, easily and atraumatically reach a screw fixation position on a vertebral arch pedicle, expose a facet joint, bluntly separate the multifidus muscle from the vertebral arch, accurately place the retractors, and thereafter locally form a surgical operation tunnel space that externally extends 10 degrees to 15 degrees. A design of angles and structures of retractors effectively protects local soft tissues and prevents a tissue damage while executing traction on local muscles and ensuring an adequate surgical space.
