A surgical cutting instrument including a first tubular member, a second tubular member, a sleeve member, a third tubular member, and an orientation member. A distal section of the first tubular member includes a cutting tip. The distal region of the second tubular member forms a cutting window. The first elongated member is co-axially disposed within the second tubular member such that the cutting tip is selectively exposed at the cutting window. The first and second tubular members are co-axially disposed within the sleeve member. The third tubular member is co-axially disposed around the intermediate section of the first tubular member, the intermediate region of the second tubular member and the sleeve member. The orientation member is rotatable to transmit a rotational force applied to the orientation member to selectively rotate the second and third tubular members relative to the sleeve to effectuate spatial rotation of the cutting window. |

1. A surgical cutting instrument comprising:
a first tubular member having a proximal section, an intermediate section, and a distal section, wherein the distal section includes a cutting tip; a second tubular member having a proximal region, an intermediate region, and a distal region, wherein the distal region forms a cutting window, wherein the first elongated member is co-axially disposed within the second tubular member such that the cutting tip is selectively exposed at the cutting window; a sleeve member having a proximal end and a distal end, wherein the first and second tubular members are co-axially disposed within the sleeve member; a third tubular member, wherein the third tubular member is co-axially disposed around the intermediate section of the first tubular member, the intermediate region of the second tubular member and the sleeve member; and an orientation member rotatable to transmit a rotational force applied to the orientation member to selectively rotate the second and third tubular members relative to the sleeve to effectuate spatial rotation of the cutting window. |
