Abstract

A method for ultrasonically treating tissue includes accessing a surgical site with an ultrasonic surgical instrument, dissecting tissue with a first portion of the blade, and sealing tissue with a second portion of the blade. The instrument includes a blade that defines a longitudinal axis. The blade is configured to oscillate along the longitudinal axis to ultrasonically treat tissue.

Claims

1. A method for ultrasonically treating tissue comprising:

accessing a surgical site with an ultrasonic surgical instrument, the instrument including a blade defining a longitudinal axis;

dissecting tissue with a first portion of the blade; and

sealing tissue with a second portion of the blade.

2. The method of claim 1, wherein the blade includes a top portion, a bottom portion, and side segments defined between the top and bottom portions and the first portion is the bottom portion.

3. The method of claim 2, wherein the second portion is the top portion.

4. The method of claim 2, wherein dissecting tissue with the bottom portion includes contacting tissue with a notch defined on the bottom portion.

5. The method of claim 2, wherein sealing tissue includes clamping tissue between the top portion and a jaw pivotally movable relative to the blade.

6. The method of claim 5, wherein sealing tissue includes applying pressure to the tissue.

7. The method of claim 6, wherein applying pressure to the tissue includes clamping the tissue between the top portion and a jaw pivotally movable relative to the blade.
