Abstract

The invention relates to an instrument for endoscopic therapy. A cutting tool including a rigid tubular shank is so guided within a tubular longitudinally slotted instrument shank having an essentially oval inner cross section, that the cutting tool may be tilted out of the axis of the instrument shank, whereby a cutter of the cutting tool penetrates the longitudinal slit of the instrument shank and projects beyond the diameter of the instrument shank. In this way by varying the tilting angle of the cutting tool the cutting depth of the cutting tool may be delicately set.
