Abstract
Abstract A rib retracting instrument for mounting on a surgical table employs a rigid, elongated boom member provided with swivel means at the top of the boom member. The swivel means is rotatable about a first axis parallel to the length of the boom member and about a second axis which is perpendicular to the first axis. A manually operable retracting member is connected to the swivel means to rotate therewith in all planes. The retracting member extends through the swivel means for linear movement with respect thereto, the retracting member being adjustable to self-retained position.
