Current invention relates to a combined system developed for the purpose of use in the treatment of anorectal fistulas. Fistulectomy Set is a system consisting of fistulectomy units which functions fully controlled and transmitting the pivoted movement which comes from the movement providing and transmitting part to the cutting edge by moving it on a central guide with the help of a motion carrier flexible shaft consisting of hexahedron spheroid parts. It consists of a cannulation apparatus which provides a simultaneous rotation, vibration and reciprocating movement and which detects the fistula trace fully and accurately. With this cutting edge, a channel surrounded by living tissue is obtained by cutting around the fistula trace cylindrically with suitable thickness, and thus cutting the secretory mucosa, dead tissues and fibrotic structures. With the developed system, it is believed that important progress will be made in the treatment of anorectal fistula； an important social and medical problem. It will prevent the loss of labor force, shorten hospital stays, reduce costs and minimize complications of treatment. Most importantly, it will prevent anal incontinence and hence a very important problem will be solved.La présente invention concerne un système combiné mis au point pour les fins d'une utilisation dans le traitement de fistules ano-rectales. L'ensemble de fistulectomie est un système constitué d'unités de fistulectomie et de fixation qui fonctionne totalement commandé sur un axe et transmettant le mouvement de rotation qui vient de la partie de fourniture et transmission du mouvement au bord tranchant en le déplaçant sur un guide central à l'aide d'une tige souple vectrice de mouvement constituée de parties sphéroïdes hexaédriques. Il est constitué d'un appareil de canulation qui fournit un mouvement simultané de rotation, de vibration et de va et vient et qui détecte totalement et précisément le trajet fistuleux. Avec ce bord tranchant, un canal entour
