Abstract
A surgical instrument configured to cut tissue includes an outer member and an inner member at least partially received within the outer member. The outer member includes a cutting window near a distal end thereof. A driving assembly is coupled to the inner member and configured to cause the inner member to rotate around and move along a longitudinal axis of the outer member. A controller is configured to control the driving assembly to control at least one of an angular position, an angular velocity, or an angular acceleration of the inner member according a plurality of piecewise continuous profiles. The initial and final angular velocities of the inner member are zero, and the inner member cuts tissue extending into the cutting window.
