An electrode assembly is provided for use in a resectoscope, comprising an elongate shaft, at least one arm depending from the shaft, elongate connection means for connecting the arm to a source of electrosurgical energy, and an electrode 35 at the end of the arm. The arm includes a suction lumen extending from a proximal end to a distal end, the distal end of the suction lumen 36 terminating in the general region of the tissue treatment element (electrode) 35, and the proximal end of the suction lumen including second connection means for connecting the suction lumen to a source of suction. A hood 43 may direct material from the treatment electrode 35 to the suction lumen opening 36. The treatment element may be a button electrode, cutting loop, roller electrode or slider electrode. The electrode may depend from two connective arms, each of which is provided with a suction lumen 36. The resectoscope may have its own suction lumen. |
