The present invention relates to a tissue removal device with a body tissue for a shaver and remove them. And the support has a passageway therein, a hollow member extending in the shaver is, the longitudinal direction, and the outer cutting window is formed with a fixed blade, the outer tube portion is formed curettes; Have a suction passage therein as a hollow member which is rotatably inserted into the installation shaft in the support passages of the outer tube, in a position corresponding to the outer cutting window of the front end portion of the rotating blade is formed, but opens the suction passage in the lateral direction It provided with a cutting window that is inside and include an inner tube extends out of the rear end of the outer tube.
Body tissue removal shaver of the present invention is composed as described above, by having a curettes to the front end, it may be scratched by abnormal tissue attached flat drop in normal tissue surface in the body, excellent in much tissue removal efficiency, of the outer tube and, while being of a mutually different patterns on the cutting window close to one another form the fixed blade form a downwardly inclined groove, excellent the chopped effect of the tissue, particularly to increase the volume of the tissue to be sucked into the interior of the cutting window of the chopped operation time It can be shortened.
