<p>A combined system aiming at the treatment of anal fistula has been developed. Fistulectomy set contains, a vibrating guide facilitating localisation and cannulation of the fistula tract and a fistulectome which is an electromotor-driven instrument transfering 3 D axial movement by means of spherical joints threaded along the central spiral guide to the blade at the tip. We believe that this set will provide significant advantages in the treatment of anal fistulas namely shortening the hospital stay and convalescance period, reducing the cost of the treatment, minimizing the postoperative morbidity and more importantly, prevention of inadvertant anal incontinance.</p> |
