Abstract

An ultrasonic surgical blade that includes a blade body that has a treatment region. At least one indentation can be formed in the treatment region of the blade body wherein each indentation forms a tissue cutting edge with an outer surface of the blade body. The indentation may comprise one or more holes, lumens, grooves or dimples or a combination of such structures. In various embodiments, one or more aspiration lumens are provided in the surgical blade which may ultimately communicate with an aspiration lumen or passage in an ultrasonic surgical instrument.

Claims

1. An ultrasonic surgical blade comprising:

a substantially spherically-shaped blade body having an treatment region; and

at least one dimple formed in said treatment region of said blade body wherein each dimple forms a tissue cutting edge with an outer surface of said blade body.

2. The ultrasonic surgical blade of claim 1 further comprising an ultrasonic transmission member having a proximal end and a distal end wherein said distal end is coupled to said blade body.

3. The ultrasonic surgical blade of claim 2, wherein said ultrasonic transmission member is configured to transmit at least one of a longitudinal motion, transverse motion and torsional motion from a corresponding source of said longitudinal motion, transverse motion, and torsional motion communicating therewith to said blade body.

4. The ultrasonic surgical blade of claim 3, wherein said ultrasonic transmission member is configured to transmit a combination of said longitudinal motion, transverse motion, and torsional motion to said blade body.
