ABSTRACT:
A surgical instrument assembly has an endoscope with an instrument channel and a sheathed elongate tubular member inserted into the instrument channel. The sheath is provided with a distal end portion having at least one resiliently biased, curved portion tending to direct the tip of the distal end portion in a direction angularly offset from the axis of the body insertion tube at its distal end. The elongate tubular member is itself longitudinally slidably positioned within the sheath. The instrument channel exerts forces sufficient to straighten the curved portions of the sheath when the curved portions are positioned within the body insertion tube, proximal of the tube's distal end. An elongate flexible endoscopic instrument is mounted into the tubular member so that an operative tip is located at a distal end of the tubular member.
