Abstract
A surgical instrument is provided having a tubular body including a distal portion, a proximal portion and a mid portion. A cutting member having a cutting edge is longitudinally received within the tubular body for guided reciprocal movement therein between a cutting position wherein the cutting edge extends from the distal portion and a non-cutting position wherein the cutting edge is retracted within the tubular body. A urging mechanism is also provided within the mid portion of the tubular body for urging the cutting member to the cutting position. A vacuum source is coupled to the cutting member at a proximal end thereof and provides a vacuum directed to the distal portion to hold tissue to be cut. A method of cutting the tissue is also provided.
