SURGICAL CUTTING INSTRUMENT

摘要

PROBLEM TO BE SOLVED: To provide a surgical cutting instrument capable of effectuating rotation of a cutting window relative to a handpiece without occupying both of the surgeon's hands.

SOLUTION: The surgical cutting instrument includes: a first tubular member 312; a second tubular member 316; a handpiece 308; a first hub 330; a second hub 350; a third hub 392; and an actuator assembly 310. The first tubular member has a cutting tip 314 and is co-axially disposed within the second tubular member such that the cutting tip is exposed at a cutting window 318. The first hub is mounted to the first tubular member and is movably coupled to the handpiece. The second hub is mounted to the second tubular member and defines a hub axis. The actuator assembly rotatably couples the second hub to the handpiece and includes an actuator. Movement of the actuator is translated to rotational movement of the second hub so as to effectuate spatial rotation of the cutting window.
