1. A tissue resecting device, comprising:
a housing including an elongated outer shaft extending from a distal end thereof, the outer shaft including a tool portion disposed at a distal end thereof, the tool portion including a window defined therein;
an inner shaft disposed within the elongated outer shaft and including proximal and distal ends, the inner shaft configured to rotate upon actuation thereof, the inner shaft including a cutting member disposed at the distal end thereof in concentric alignment with the tool portion and configured to rotate concomitantly with the inner shaft, the cutting member including:
a series of slots defined in the cutting member configured to facilitate articulation of the cutting member and cut tissue upon rotational engagement with the slots; and
a blade disposed at a distal end of the cutting member configured to cut tissue upon rotational engagement therewith, the blade operably disposed within the window of the tool portion; and
an actuator operably disposed on the housing and configured to articulate the tool portion and the cutting member upon actuation thereof between a neutral position wherein the blade is aligned for radial cutting and one or more articulated positions wherein the blade is aligned for varying degrees of axially-aligned cutting.
