Abstract
A surgical instrument for cutting tissue includes a sleeve, a shaft slidably disposed within the sleeve and defining a longitudinal axis, and a plurality of legs coupled to the shaft and disposed about the longitudinal axis. Each leg has a blade attached to an end portion thereof and each blade defines a cutting edge. The shaft is slidable relative to the sleeve between a collapsed configuration, wherein the legs are disposed within the sleeve, and an expanded configuration, wherein the legs extend distally and radially outwardly from the sleeve. In the expanded configuration, the cutting edge of each blade is disposed in a proximally-facing orientation. Alternatively, the shaft is rotatable relative to the sleeve to rotate the legs about the longitudinal axis, thereby rotating each blade through a circular cutting path defining a different diameter. Methods of cutting tissue are also provided.
