Which thermal method of hemostasis utilizes intense, focused light?

Laser
Bipolar
Harmonic
Monopolar

The correct answer is: Laser

The thermal method of hemostasis that utilizes intense, focused light is the laser. Lasers work by emitting a concentrated beam of light at a specific wavelength that can precisely cut tissue or coagulate blood vessels without causing significant thermal damage to surrounding tissues. This precision allows for effective hemostasis, as the heat generated can seal blood vessels and minimize bleeding during surgical procedures. The use of lasers is beneficial in various surgical specialties due to their ability to provide a clear surgical field and reduce recovery time for patients. Other methods like bipolar and monopolar techniques work by passing electrical current through tissues to generate heat for hemostasis, while harmonic methods utilize ultrasonic vibrations. However, none of these methods use focused light like lasers do, which sets laser technology apart in its application for hemostatic control.
