Abstract
Abstract An endoscope is provided through which diagnostic, therapeutic or surgical apparatus can be inserted. The endoscope includes a tubular body having an eyepiece at its proximal end portion of a catheter structure and fiber optics extending from its distal end portion. An image at a distal end of the fiber optics is viewable through the eyepiece. A side tube has its distal end portion attached to the tubular body and has its proximal end portion extending towards that of the tubular body. The lumen of the side tube serves for inserting surgical apparatus via said catheter structure into a body cavity, opening or conduit. The side tube and the tubular body define a bisecting plane which substantially bisects the tubular body. A reference plane is perpendicular to the bisecting plane and passes through a longitudinal axis of the tubular body. A handle extends generally on an opposite side of the reference plane from the side tube. The handle includes a back-of-hand engaging portion extending generally along and spaced apart from the tubular body, whereby an operator's hand fits between the tubular body and the handle with the palm of the hand against the tubular body and with the back of the hand against the back-of-hand engaging portion of the handle. Thus, the operator's fingers can position diagnostic, therapeutic or surgical apparatus through said catheter structure.
