Abstract
A surgical instrument includes an elongate hollow probe having first and second apertures (4 and 5) at its distal end portion. An elongate drive shaft disposed within the probe (1) and mounted for rotation about its longitudinal axis within the probe. A cutting tool (2, 34) is located at the distal end of the drive shaft, and is positioned adjacent to the first aperture (4). A bipolar electrosurgical device (3) is located at the distal end of the probe (1) in the region of the second aperture (5). The electrosurgical device includes an active electrode (13) and a return electrode (11) separate and insulated therefrom. A motor (6) is provided for rotating the drive shaft; and suction means is provided for selectively providing a source of suction at either the first apertures (4) or the second aperture (5).
