Abstract
An adjustable self retaining retractor ring assembly is provided. The self retaining retractor ring assembly is formed from two half-rings connected together by hinges to form a 360° enclosure or ring. The hinges allow the two half-rings to bend or pivot 180° relative to a plane of the ring. One of the hinges includes a positionable locking mechanism to lock or set the angular orientation of the two half-rings relative to each other. In this manner, fixed angles for the half-rings can be selected and maintained. Each half-ring includes a plurality of axially protruding pegs or posts (relative to a plane of the half-ring) positioned thereabout. The posts are shaped to releasably accept retractors and/or ancillary instruments thereon. Additionally, each post preferably includes a slot configured to allow for the locking of suture material therein.
