Abstract:
1. A surgical cutting instrument comprising: a first elongated member having a proximal section and a distal section having a cutting tip; a second tubular member having a proximal region and a distal region forming a cutting window, wherein the first elongated member is co-axially disposed within the second tubular member such that the cutting tip is exposed at the cutting window to cause cutting of tissue therebetween as the first elongated member rotates; a handpiece; a first hub mounted to an exterior of the proximal section of the first elongated member and rotatably coupled to, and disposed entirely within, the handpiece; a second hub mounted to the proximal region of the second tubular member and rotatably coupled to the handpiece, the second hub defining a hub axis; and an actuator assembly coupling the second hub to the handpiece, the actuator assembly including an actuator rotatably mounted to the handpiece such that a portion of the actuator is exteriorly exposed for manual interface by a user and rotates about a rotational axis; wherein the actuator assembly is adapted to translate a movement of the actuator to a rotational movement of the second hub relative to the handpiece to effectuate spatial rotation of the cutting window, wherein the rotational axis is perpendicular to the hub axis.
