Patent ID: 7241299

Claim:
A surgical extractor for extracting foreign bodies through natural or surgical passages comprising: a flexible tube which is able to penetrate inside said passages as far as such a body to be extracted; a longitudinally rigid maneuvering wire which is able to slide in said flexible tube and can be maneuvered slidably, from the outside, via its proximal end; and a plurality of wire loops arranged at the distal end of said maneuvering wire and capable of adopting, under the action of the latter: a trapping position, for which said loops are deployed and form, outside the distal end of said flexible tube, an openwork cage in the at least approximate shape of a globe, each loop forming a meridian plane thereof, and an extracting position, for which said loops are flattened and retracted at least partially inside the distal part of said flexible tube, said wire loops intersecting at their distal ends and being joined to one another there, wherein, at the place of the distal intersection of said wire loops, said surgical extractor comprises a tongue formed in the wire of one of said wire loops and configured in a passage through which each other wire loop can pass with play and slide to a limited extent while maintaining at least approximately its squareness with respect to said wire loop having said tongue.
