ABSTRACT: We
present a laser resection technique to be used when biotissue is heated by
laser radiation to the temperature of material softening and then moved apart
by the lateral edge of the optical fiber with a strongly absorbing tip. The
absorbing tip allows the decrease in the power of effective cutting of the
laser scalpel at the wavelength of 0.97 μm. And it changes the resection speed
as well as the characteristics of the damage of the tissues adjacent to the incision
in experiments on model media and experimental animals.
