The blade may comprise a distal cutting end, a distal non-cutting end, and an intermediate portion that extends coaxially from the distal cutting end to the distal non-cutting end. The distal cutting end may be located outside of a housing of the instrument； the distal non-cutting end may be located at a posterior end of a suction portion inside the housing； and the intermediate portion may extend coaxially from the distal cutting portion, completely through a chamber portion of the housing, and to the suction portion to the distal cutting end. This configuration allows for biological material to be cut and aspirated completely through the disposable blade and housing to a suction source, avoiding contamination and improving instrument sterilization for surgeries.2/6 C=% C%4 _ -3 CM, C7%o IMP
