Abstract
An ultrasonic surgical cutting method and apparatus is provided wherein the method and apparatus allows for the cutting of bone from within a hollow pathway such that a cutter associated with the ultrasonic method and apparatus remains sufficiently cool to prevent necrosis of the bone being cut. Furthermore the ultrasonic device and method can be employed in the cutting of soft tissue, wherein a cooled cutter is used to prevent the sticking of soft tissue to the cutting blade of the device during use.
