Scattered in recent years the limitations of multiple foci or the use of heart-cutting, high-temperature continuous output laser therapy, surgery may be open or porous fibers microscope. Its purpose is to output laser power from the center, so that heat to destroy the cancer spread to the surrounding tissue. Conditions which have been placed in the hospital ultrasound and CT B-monitored treatment. Advantage of light wound injury, only needle (7 ~ 8) large, multi-point can be carried out faster treatment of patients suffering mild, and repeatedly do. Foci were damaged by high temperatures fibrosis repair, is the treatment of advanced liver cancer, a promising measure. Reported in the literature based on clinical observation and better than chemotherapy, and used widely in clinical practice. The customer can choose the hot-sell laser pointer  .
Nd: YAG laser surgery of the advantages: hemostatic properties, such as the first portal in the block under the conditions of operation, regardless of vaporization resection of liver cancer, or method, little or no bleeding bleeding artery diameter of 2mm thermal coagulation can be closed; vaporization of multiple liver nodules can be treated, one by one to eliminate cancer, the cancer nodules 1cm in diameter, generally only 1 minute to completely vaporized; with severe cirrhosis of the liver, if the cancer swollen and in the right lobe of the liver, liver cancer, especially small, to do with the laser vaporization or Local excision can be done free of conventional right liver resection, which can retain more of the liver tissue, cirrhosis due to a corresponding reduction in And to do right liver resection caused high mortality. The result of the mutual inspection of laser pointer  matters a lot. 
According to the PN junction reverse characteristics shows that, in a certain range of reverse voltage, reverse current is very small and saturated. At this point, if the light exposure of PN junction, due to the intrinsic excitation of the electron - hole for a limited number of reverse saturation current remains constant, called the photodiode dark current.
Eschar cutting the size of the laser power used when a very important, the laser output power as high temperature and high dissolved into leaving the subcutaneous adipose tissue burning oil easily understood, some articles reported that nitrogen method used to blow the fire, blowing nitrogen also protect the surrounding normal organizations from the less heat damage. Control and power conditioning to the subcutaneous tissue that is not dissolved, without damage to surrounding tissue is very important. Do not power fast, short cut, but according to the burns, the extent of the use of laser power, of course, used in cutting the power, except when eschar.
