Abstract
A resectoscope having a curved sheath that can be made with different lengths, diameters and radii of curvature to better reach the areas of the bladder that are not accessible with a conventional resectoscope. The device is equipped with a fiber optic scope that follows the curved electrode tube and can transmit images for observing the interior of bladder where the surgical procedure is performed. The device of the present invention further comprises a modified obturator to facilitate the movement of the sheath inside the body, and interior guides on the sheath help move the cutting tool and obturator through the curved portions of the sheath.
