Q

When the active jaw of an ultrasonic dissection device is in contact with tissue, the mechanical vibrating motion causes proteins in the tissue to become denatured as hydrogen bonds are broken; as a result

A) The protein molecules become disorganized and form a sticky coagulum, which has the potential to weld and coagulate the smaller bleeding vessels
B) The collagen and elastin in the vessel walls melt, reforming into a permanent, plastic-like seal
C) The flow of electrical current creates high tissue temperatures, leading to rapid expansion of intracellular fluids and cell explosion or vaporization

A

A) The protein molecules become disorganized and form a sticky coagulum, which has the potential to weld and coagulate the smaller bleeding vessels

Q

True or False. The active jaw of an ultrasonic dissection device moves at a set frequency of 55,500Hz. As the power level changes from max to min, the frequency remains the same, but the distance that the active jaw is displaced, becomes longer, thus increasing the coagulation/hemostatic effect.

A

False
