Abstract
A resectoscope and a method of use for removing organic tissue, e.g., the prostate gland, from the body of a living being. The resectoscope includes an elongated member having a distal end adapted to be introduced into the body of the being at the situs of organic tissue to be removed via a tubular sheath. The resectoscope includes a laser for producing a laser beam adjacent the distal end of the elongated member to penetrate several millimeters through the surface of the tissue to coagulate. A rotatable cutter, e.g., a pair of angled offset planar blades, is disposed at the distal end of the elongated member and is arranged to be rotated at a high rate of speed by an associated drive assembly to cut the coagulated tissue. A lumen is provided to carry an irrigation liquid to the situs of the tissue. A suction lumen is provided to carry the tissue removed by the cutter so that it can be retrieved for histological examination. A viewing system is also provided and extends through the resectoscope in order to enable the operator to view the lasing and cutting of the tissue.
