Abstract

The instrument is designed as an inner pipe (8) provided with a blade (10) integrated in its tip and rotating inside an outer pipe (4) attached to a drive unit (2) accommodated inside the operation handle. A short open stretch (6) at the side of the tip of the outer pipe (4) facilitates the tissue to be pulled into the instrument and to be chopped between the rotating blade (10) and the rim surrounding the opening (6). The blade (10) is provided with a row of holes (14) in order to allow a constant flow of the rinsing fluid, preventing the blade (10) from getting jammed as well as creating a suction effect.
