A deflectable surgical shaver tool comprises a blade with a rotatable cutting shaft comprising a distal cutting end and a proximal non-cutting end, a fixed outer sheath coaxially surrounding the rotatable cutting shaft, a cutting window at the distal cutting end, and at least a portion that is deflectable. The surgical shaver tool may further comprise an actuator； a handpiece； and a first wire and a second wire, each operatively coupled to the actuator at a proximal end and to the deflectable section at an opposite distal end. The first wire and the second wire are configured to control deflection of the deflectable portion when the actuator is manipulated. This configuration allows for the curvature of the blade to be changed for more efficient surgical procedures and prevents harm to the patient.
