Abstract
Official abstract text for this publication.
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 may include 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. A tissue collector may also be provided and is in fluid communication with the lumen of the inner cannula. The inner cannula reciprocates at a rate that is greater than 1000 reciprocations per minute, and variable aspiration may also be provided to the device to control tissue traction and provide fine shaving and debulking.
