Title: DEVICE AND METHOD FOR RESECTING BODY TISSUES
Abstract:
A resecting device for use in tissue removal is disclosed. The resecting device includes a cannula (12) having a hollow (14) which is sized for introduction into a body. The cannula (12) is formed with at least one, preferably a plurality of, cutting openings (22) each having a cutting edge (24). The resecting device further includes a rotating mechanism (26) which is connectable through a shaft (28) to the cannula (12), and which serves for rotating the cannula (12) around a longitudinal axis thereof. As a result of such rotation, the cannula's construction when the cannula (12) is contacted with the tissue, the cutting edges (24) of the cutting openings (22) dissect the tissue, and direct the dissected tissue through the openings (22) into the hollow (14) of the cannula (12).
