Abstract
A tissue cutting device that is especially suited for neurosurgical applications is disclosed and described. The device includes a handpiece and an outer cannula in which a reciprocating inner cannula is disposed. The inner cannula includes a hinge between a body section and a cutting section that allows the cutting section to pivot when the inner cannula reciprocates within the outer cannula. The inner cannula also includes a bending portion between the proximal end of the inner cannula and the hinge which is bendable with the outer cannula. The device is particularly suited for accessing neurosurgical sites that are not accessible along a linear path.
