Abstract

CET INSTRUMENT A EXTRAIRE DES CORPS DE CANAUX TELS QUE LES URETERES, ARTERES, BRONCHES, ETC., COMPREND UN TUBE FLEXIBLE 1 QUI EST INTRODUIT DANS LE CANAL PHYSIOLOGIQUE ET PRESENTE A SON EXTREMITE COTE APPLICATEUR UN ORGANE DE MANOEUVRE 5 ET A SON EXTREMITE COTE SONDE UN ELEMENT EXPANSIBLE ELASTIQUE 6 QUI EST FIXE, D'UN COTE, A L'EXTREMITE DU TUBE ET, DE L'AUTRE COTE, A L'EXTREMITE D'UN ELEMENT DE COMMANDE 4 ET SE DILATE OU SE RESSERRE SOUS L'ACTION DE L'ORGANE DE COMMANDE 4 ENFILE A TRAVERS LE TUBE 1 ET SOLIDAIRE DE L'ORGANE 5. SUIVANT L'INVENTION, L'ELEMENT 6 EST UN TRONCON DE TUBE TISSE OU TRESSE DONT LES FILS SONT SITUES A UN CERTAIN ECARTEMENT MUTUEL ET PRESENTENT UNE ALLURE SENSIBLEMENT HELICOIDALE LORSQUE L'ELEMENT EST NON DILATE. LORSQUE L'INSTRUMENT A ETE INTRODUIT DANS LE CANAL, ON DILATE L'ELEMENT, LEQUEL RESTE ALORS PERMEABLE AUX LIQUIDES MAIS PERMET D'ENTRAINER LES CORPS A EXTRAIRE LORSQU'ON RETIRE L'INSTRUMENT.THIS INSTRUMENT TO EXTRACT BODIES FROM CHANNELS SUCH AS URETERIAS, ARTERIES, BRONCHES, ETC., INCLUDES A FLEXIBLE TUBE 1 WHICH IS INTRODUCED INTO THE PHYSIOLOGICAL CHANNEL AND PRESENTS AT ITS END APPLICATOR SIDE A OPERATING ORGAN 5 AND AT ITS END SIDE AN ELASTIC EXPANDABLE ELEMENT 6 WHICH IS FIXED ON ONE SIDE AT THE END OF THE TUBE AND, ON THE OTHER SIDE, AT THE END OF A CONTROL ELEMENT 4 AND EXPANDS OR TIGHTENS UNDER THE ACTION OF THE CONTROL UNIT 4 THREADS THROUGH TUBE 1 AND IN PART OF THE UNIT 5. ACCORDING TO THE INVENTION, ELEMENT 6 IS A TRUNCON OF WOVEN OR BRAIDED TUBE WHOSE WIRES ARE LOCATED AT A CERTAIN MUTUAL DISTANCE AND HAVE A SENSITIVELY HELICOIDAL APPEARANCE WHEN UNDILATED ELEMENT. WHEN THE INSTRUMENT HAS BEEN INSERTED IN THE CHANNEL, THE ELEMENT IS DILATED, WHICH THEN REMAINS PERMEABLE TO LIQUIDS BUT ALLOWS TO TRAIN THE BODIES TO BE EXTRACTED WHEN THE INSTRUMENT IS REMOVED.
