Abstract
An ultrasonic surgical tool comprises a substantially planar blade body having a pair of opposed lateral surfaces and a cutting edge. A shank integral on a distal side with the blade body is provided at a proximal side with a connector for operatively linking the blade to a source of ultrasonic mechanical vibrations. The blade body is provided in at least one of the lateral surfaces with a shallow recess which is nearly coextensive with that lateral surface. The blade body has a raised rim surrounding and defining the recess, the rim being narrow on the three sides between the recess and the cutting edge.

11. An ultrasonic surgical tool comprising:
-
a substantially planar blade body having a pair of opposed major faces, said blade body having a peripheral flange extending along three sides of said blade body and defining a recess in at least one of said major faces, said recess being substantially coextensive with said blade body, at least a portion of said flange having a cutting edge or surface; and a shank integral on a distal side with said blade body and provided at a proximal side with a connector for operatively linking the blade to a source of ultrasonic mechanical vibration. - View Dependent Claims (12, 13, 14, 15, 16, 17, 18, 19, 20)
