Abstract
An elongate tubular body extends between a rotatable cutter and a control. The cutter is connected to the control with a rotatable element. A vacuum is applied through an annular passage defined between the tubular body and the rotatable element. The control has an indicator that reveals resistance to rotation and/or reduction in flow. Material that has been processed by the cutter is aspirated through the tubular body for disposal. The control enables rotation of the rotatable element only following application of a predetermined level of vacuum.
