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:

an ultrasonic transmission member;

a substantially spherically-shaped blade body protruding from said ultrasonic transmission member and having a treatment region;

a first lumen extending at least partially through said ultrasonic transmission member and at least a portion of said blade body;

at least two dimples 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; and

at least one second lumen extending at least partially through another portion of said blade body and intersecting said first lumen for fluid communication therewith, wherein said at least one second lumen is in fluid communication with said at least two dimples.

2. The ultrasonic surgical blade of claim 1, wherein said at least one second lumen extends along an axis that is substantially perpendicular to a longitudinal axis.

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.

5. The ultrasonic surgical blade of claim 1 further comprising an aspiration member communicating with said first lumen.

6. The ultrasonic surgical blade of claim 1, wherein said first lumen is in fluid communication with at least one of an aspiration module and an irrigation module.

7. An ultrasonic surgical instrument, comprising:

a fluid motivation module;

a transducer; and

an ultrasonic surgical blade, comprising;

an ultrasonic transmission member;

a blade body protruding from said ultrasonic transmission member, said blade body including a treatment region, wherein said blade body comprises a substantially spherically-shaped distal portion;

a first lumen extending at least partially through said ultrasonic transmission member and at least a portion of said blade body;

an inlet distal to said transducer, said inlet configured to couple said first lumen to said fluid motivation module;

a plurality of dimples 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; and

at least one second lumen extending at least partially through another portion of said blade body and intersecting said first lumen for fluid communication therewith, wherein said at least one second lumen is in fluid communication with said plurality of dimples.

8. The ultrasonic surgical instrument of claim 7, wherein said at least one second lumen extends along an axis that is substantially perpendicular to a longitudinal axis.

9. The ultrasonic surgical instrument of claim 7, 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.

10. The ultrasonic surgical instrument of claim 9, wherein said ultrasonic transmission member is configured to transmit a combination of said longitudinal motion, transverse motion, and torsional motion to said blade body.

11. The ultrasonic surgical instrument of claim 7 further comprising an aspiration member communicating with said first lumen.

12. The ultrasonic surgical instrument of claim 7, wherein said first lumen is in fluid communication with at least one of an aspiration module and an irrigation module.
