Researchers using optical fibers to introduce laser beams in surgery have invented a new diode laser that is ideal for soft tissue surgery, which produces a laser beam that can be introduced with a very thin optical fiber. .
Snoring is not only inconvenient, but also very laborious. For most patients, the existing solution is drug therapy, and surgical removal of the upper jaw and uvula. This operation often uses a carbon dioxide laser, but this device cannot The beam is oriented along the waveguide so that the artificial arm is used to position the beam in the correct position in the patient's mouth.
Researchers at the Fraunhofer Institute in the Aachen laser technology ILT and in the Solid Physical Snow Federation in Freiburg have invented a diode laser suitable for the right wavelength, making this The problem was solved, said ILT project manager Dr. Konstantin Boucke: "This output laser can pass a very fine optical fiber. The surgeon can simply put the flexible fiber into the patient's mouth instead of the surgery. The mirror is used to locate." This diode is special in that its wavelength is 2 microns. Boucke also said: "Light is easily absorbed by biological tissue at this wavelength, and the beam does not penetrate too far. This laser can be used to better control the surgical incision, and it can be switched to the second mode of operation, which emits 800-980 nm of light radiation, which is the ideal wavelength for stopping bleeding, which makes the new laser suitable for any type. Soft tissue surgery, including prostatectomy, can insert fibers into the urethra.
In order to produce a laser that produces this wavelength, researchers must apply unconventional materials, such as gallium germanium compounds, and corresponding optical devices. Cameras are often used to measure laser beams that are insensitive to 2 micron wavelengths.
