Abstract
An ultrasonic surgical instrument comprises a cylindrical shaft and a blade at a distal or free end of the shaft, the blade being unitary and continuous with the shaft, without an intervening joint. The shaft has a longitudinal axis and the blade includes a flat or planar blade body with a proximal end eccentrically disposed relative to the shaft axis. Thus, the blade body or at least a proximal end portion thereof is disposed eccentrically relative to the shaft. The blade in its entirely may be inclined relative to the shaft axis or extend parallel thereto.
Claims21
An ultrasonic surgical instrument comprising:
- a cylindrical shaft and a blade at a distal of free end of said shaft, said blade being unitary and continuous with said shaft, without an intervening joint.
A method for manufacturing a unitary ultrasonic surgical instrument having a shaft portion and a blade portion at a distal of free end of said shaft, said blade being unitary and continuous with said shaft, without an intervening joint, said method comprising:
- providing a tool blank including an enlarged connector portion at one end and a cylindrical shaft at an opposite end;
- and machining a distal end portion of said shaft on opposing sides thereof to form said shaft portion from said cylindrical shaft and to generate two opposing flats, thereby forming said blade portion as a planar shaft extension or end portion.
