Abstract
L'INVENTION EST RELATIVE A UN ENDOSCOPE A PINCE D'EXCISION. LE BUT DE L'INVENTION EST DE PERMETTRE, EN CAS DE BESOIN, DE TRANSFORMER LA PINCE D'EXCISION EN OUTIL DE COAGULATION PAR COURANT HAUTE FREQUENCE SANS RISQUE D'ENVOI DE COURANT A DES ENDROITS NON DESIRES. LA TIGE 5 PORTANT LA PINCE 11 EST POURVUE INTERIEUREMENT D'UNE GAINE ISOLANTE 8 QUI L'ISOLE DE LA TRINGLE DE COMMANDE 7 DE LA PINCE, ET CETTE TIGE 5 EST PROLONGEE PAR UNE RALLONGE RIGIDE ISOLANTE 10 QUI DEPASSE AU-DELA DE L'ENDOSCOPE ET AUTRES OUTILS ANNEXES, PORTE LA PINCE 11 ET EST RACCORDE A LA GAINE 8.THE INVENTION RELATES TO AN EXCISION FORCEPS ENDOSCOPE. THE AIM OF THE INVENTION IS TO ALLOW, IF NECESSARY, TO TRANSFORM THE EXCISION FORCEPS INTO A HIGH FREQUENCY CURRENT COAGULATION TOOL WITHOUT RISK OF SENDING CURRENT TO UNWANTED PLACES. THE ROD 5 CARRYING THE CLAMP 11 IS PROVIDED INTERNALLY WITH AN INSULATING SHEATH 8 WHICH INSULATES IT FROM THE CONTROL ROD 7 OF THE CLAMP, AND THIS ROD 5 IS EXTENDED BY A RIGID INSULATING EXTENSION 10 WHICH EXCEEDS BEYOND THE CLAMP. ENDOSCOPE AND OTHER ATTACHED TOOLS, HOLDING CLAMP 11 AND ATTACHED TO SHEATH 8.
