摘要： A dual function arthroscopic blade provides multiple cutting surfaces of differing cut aggressiveness for selective engagement of the desired cutting blade without retracting the instrument for changing cutting members to apply a different set of cutting edges, or blade. An inner rotating member within a stationary outer cutting member provide cutting edges defined by cutting windows on the inner and outer cutting members, and a rotational drive applies an oscillating rotation such that one of the cutting windows, corresponding to one of the sets of cutting edges, engages an extraction region such as tissue or bone. The use of different sized cutting windows allows variance in the aggressiveness of the cut, and allows selection of another cutting window by rotating the cutting member to align the selected cutting edges without requiring extraction and reinsertion in order to attach a different blade with a different cut aggressiveness.
