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 cutter has at least one radial projection which cooperates with at least one stationary element on the tubular body to cut material drawn into the tubular body. Material that has been processed by the cutter is aspirated through the tubular body for disposal.
