Abstract
An apparatus includes a body assembly, an acoustic waveguide, an ultrasonic blade, and a liquid dispensing feature. The ultrasonic blade is positioned distally relative to the body assembly. The ultrasonic blade is in acoustic communication with the acoustic waveguide. The liquid dispensing feature is positioned distally relative to the body assembly. The liquid dispensing feature is positioned adjacent to the ultrasonic blade. The liquid dispensing feature is configured to deliver a flow of cooling liquid to the ultrasonic blade.
Claims19
An apparatus comprising:
- (a) a body assembly;
- (b) an acoustic waveguide;
- (c) an ultrasonic blade positioned distally relative to the body assembly, wherein the ultrasonic blade is in acoustic communication with the acoustic waveguide;
- wherein the ultrasonic blade defines an opening proximal to a distal end of the ultrasonic blade;
- and
- (d) a liquid dispensing feature positioned distally relative to the body assembly, wherein the liquid dispensing feature is positioned adjacent to the ultrasonic blade, wherein at least a portion of the liquid dispensing feature is positioned within the opening of the ultrasonic blade, wherein the liquid dispensing feature is configured to deliver a flow of cooling liquid to the ultrasonic blade.
An apparatus comprising:
- (a) a body assembly;
- (b) an acoustic waveguide;
- (c) an ultrasonic blade positioned distally relative to the body assembly, wherein the ultrasonic blade is in acoustic communication with the acoustic waveguide, wherein the ultrasonic blade comprises a substantially flat surface along an edge of the ultrasonic blade, wherein the ultrasonic blade comprises an opening through the surface;
- and
- (d) a liquid dispensing feature positioned distally relative to the body assembly, wherein the liquid dispensing feature is positioned adjacent to the ultrasonic blade, wherein a distal end of the liquid dispensing feature is positioned within the opening, wherein the liquid dispensing feature is configured to deliver a flow of cooling liquid to the ultrasonic blade.
