ABSTRACT:
A resecting device for use in tissue removal is disclosed. The resecting device includes a cannula having a hollow and which is sized for introduction into a body. The cannula is formed with at least one, preferably a plurality of, cutting openings each having a cutting edge. The resecting device further includes a rotating mechanism which is connectable through a shaft to the cannula and which serves for rotating the cannula around a longitudinal axis thereof. As a result of such rotation and the cannula's construction, when the cannula is contacted with a tissue, the cutting edges of the cutting openings dissect the tissue and direct the dissected tissue through the openings into the hollow of the cannula.
