Abstract
A para-spinal retractor for use during surgery which includes a planar ellipsoidal ring and a plurality of retractor blades which mount in the ring. The ring has a series of generally rectangular openings on either side of the major axis, and the blades have upturned rectangular cross-sections to slidably fit the openings. The blades are set in the tissue and rotated to a vertical position so that the ring openings engage the blades to maintain the retraction. The blades have angled facets and sharp tips, and are constructed so that when blades are engaged with the ring the facets project downwardly and towards the center of the ring.
