摘要：
A screw-based retractor comprises an elongate rack having a rack axis, a plurality of arms slidably supported for translational movement on the rack, and a plurality of blades, one each supported by a respective arm at a distal portion thereof. At least one of the arms includes at its distal portion a blade releasably attached thereto. Such at least one arm comprises a plurality of links each of which is configured to allow the blade supported by such arm to be moved in plural incrementally discrete positions with each such discrete position being selectively lockable. The blade may have a fixed or variable length. Such blade may be attached to a blade receptacle movably attached to the at least one arm in a manner to provide articulation of the blade receptacle and hence the attached blade about an articulation point spaced from and not located on such arm.
