Abstract
A surgical cutter is provided for removing body tissue during surgery. The surgical cutter includes a cannula having a proximal end and a distal end and a side wall defining an interior region. The distal end of the cannula is positioned inside a patient's body during surgery with the proximal end situated outside of the patient's body. The side wall of the cannula is formed to include an orifice for receiving body tissue. The surgical cutter further includes a first annular wall fixed to the distal end of the cannula and an annular intermediate wall. The first annular wall is arranged to define an annular gap disposed between the first annular wall and the cannula side wall. The annular intermediate wall includes an annular distal edge sized to be received by the gap. The annular intermediate wall and the cannula are arranged for relative axial movement between a first position with the intermediate wall remote from the orifice and a second position with the intermediate wall received in the gap to cut tissue received in the orifice.
