Abstract
A tissue resection device includes a housing, a drive shaft, and a set of cutting inserts arranged in sequence. The cutting inserts are connected in the sequence by off-axis torque couplings so that each cutting insert may lie at an angle to an adjacent cutting insert. Each cutting insert includes at least one cutting edge, and the cutting edges in sequence form a cutting profile which may include a combination of straight and curved sections. The housing may be curved. Rotation of the drive shaft rotates the set of cutting inserts to form a cutting burr.
