Embodiment is for melting/cutting the safety and efficient system and method for decomposing calculus or other hardness of matter.
Embodiment provides the laser aid comprising combination or single emission wavelength, and at least one in wherein said wavelength sends continuous wave, and decompose calculus in order to melt/to cut, it reduces damaging surrounding tissue by the heat temperature raising limiting calculus, stops blooding simultaneously.Melting of soft tissue can be realized at an operating stage to stop blooding with intracavity simultaneously.Embodiment also can be used for treatment prostatic hyperplasia and merges bladder or calculus of urethra disease, realizes the disposable elimination of focus at a Surgery Platform by the combination of different wave length laser.
According to clinical trial and the testing in vitro of Histological results, 1470nm is the wavelength band of eye-safe, and water has high absorbability to it.When the radiation of high absorption is applied to aqueous medium, hydrone obtains height and Fast Heating, and this extremely high speed and instant heating can cause Quick steam to expand, thus are producing high energy in local.Use the 1470nm that is very easily only absorbed by the water and continuous radiation just can produce the superenergy that can destroy hardness of matter.
When this laser module launches continuous radiation by the optical fiber of output unit to calculus, can be highly absorbed in the target analyte in its around/overwrite media, thus the evaporation causing stone, calculus to destroy and cavitation effect, thus effectively realize calculus melt Sum decomposition, and to excrete with body fluid.Therefore make operation process become feasible, rapidly and wound is little, hurtless measure, healing are very fast, solve the difficult problem on laser medicine.
Wavelength selects 980nm power to be 180W, and this wavelength has excellent absorbability in blood and in water, has (medium) poor absorbability, and it acts on structural infiltration is about 2-3mm, utilizes this feature can effectively realize melting of soft tissue.Utilize it to the low absorbability of water simultaneously, the tissue vaporization relevant to hemostatic effect can be produced and transparently to bleach, therefore it also has and effectively strengthens hemostatic effect.In this example, laser module crosses the continuous radiation of the fibre optical transmission 980nm wavelength of output unit to realize melting of intracavity soft tissue, solidify surrounding tissue simultaneously, realize the hemostasis of tissue, minimum pyrolytic damage is maintained to surrounding tissue, shorten operating time simultaneously, improve procedure efficiency.
