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.
Claims22
An ultrasonic surgical instrument, comprising:
- a cylindrical shaft having a longitudinal axis, the cylindrical shaft including a channel extending from a proximal end to a distal end thereof;
- and
- a blade with a flat or planar blade body that is unitary and continuous with the distal end of the cylindrical shaft, the flat or planar blade body having two major lateral surfaces parallel to one another, the flat or planar blade body including, in at least one of the two major lateral surfaces, a longitudinal groove that is continuous with the channel.
An ultrasonic surgical instrument, comprising:
- a shaft having a longitudinal axis, an outer surface and an end face at a distal or free end of the shaft, the shaft having a longitudinal channel extending to an outlet in the end face;
- a blade connected to and contiguous with the distal or free end of the shaft at the end face, the blade being inclined with respect to the longitudinal axis;
- and
- a connector portion at a proximal end of the shaft and configured to be attached to an electromechanical transducer device,
- the shaft extending in a straight-line or linear configuration from the connector portion to the blade,
- the blade including:
- a pair of major lateral surfaces;
- a through hole extending between the pair of major lateral surfaces, the through hole being located distally of and spaced from the end face of the shaft;
- and
- a groove contiguous and communicating with the through hole.
An ultrasonic surgical instrument, comprising:
- a cylindrical shaft having a longitudinal axis, a cylindrical outer surface, and an end face at a distal or free end of the cylindrical shaft;
- a blade connected to and contiguous with the distal or free end of the longitudinal shaft at the end face;
- and
- a connector portion at a proximal end of the cylindrical shaft and configured to be attached to an electromechanical transducer device,
- the cylindrical shaft extending in a straight-line or linear configuration from the connector portion to the blade,
- the blade including a flat or planar blade body being inclined with respect to the longitudinal axis,
- the flat or planar blade body extending within a cylindrical envelope, inclusive of the cylindrical envelope, that is coaxial and co-cylindrical with the cylindrical outer surface of the cylindrical shaft.
