Abstract
A surgical extractor for extracting foreign bodies through natural or surgical passages may include a flexible tube that penetrates inside the passages, a longitudinally rigid maneuvering wire that slides in the flexible tube and maneuvers slidably via its proximal end, and wire loops at the distal end of the maneuvering wire that may adopt a trapping position and an extracting position. The wire loops are joined at their distal ends where a tongue is formed in one of the wire loops and configured as a passage through which the other wire loops can pass with play and slide to a limited extent while maintaining squareness with respect to the wire loop having the tongue.
