Figure 3 Dissection technique around the feeding artery. A and B: The dissection around the feeding artery is enlarged by sealing while clamping with the ultrasonic surgical blade and the tissue pad of the Harmonic ACE, applying the tissue pad to the vessel side in order to decrease the thermal damage to adjacent structures; C and D: It is necessary to force the blade in the direction against the feeding artery when the ultrasonic surgical blade of the Harmonic ACE has to be applied to the feeding artery side; C shows the clamping with the ultrasonic surgical blade and the tissue pad of the Harmonic ACE; D shows the direction that must be forced with sealing.
