Review Article about Laser and its Uses

Abstract

Laser in internal medicine: Let us say that one of the most important achievements made by lasers was controlling intestinal bleeding. After part years Albert Whitman from New York used lasers to treat a 58-year-old patient. of his stomach was removed, no treatment was effective. He developed infections and required blood transfusions several times. The doctor inserted a laser beam into the patient’s stomach, connecting it to an internal endoscope. After identifying the bleeding areas with the endoscope, the doctor focused the laser beams on them. This process took a few minutes. The matter did not stop there, as current research indicates the possibility of blood YesUsing lasers in dangerous and delicate tasks, such as the liver - such as..vessels that may bleed severely during surgery to remove malignant tumors or treat wounds resulting from surgery. About accidents and other injuries, and recent studies on animals have shown that removing part of the liver with laser beams is easy and safe, with minimal bleeding, and no laser complications. It is also possible – by laser beams - to break up gallstones, as surgeons insert a laparoscope through a small hole in the abdomen, and using continuous thermal laser beams, the surgeon can separate the diseased gallbladder from the surrounding liver and pull it out through the small incision. When there are gallstones, they are broken up with shock waves and easily extracted from the gallbladder. Lasers are even used in pharmaceutical tablets and capsules, as the capsule can be punctured with a precise hole in its outer gelatinous shell using a laser, so that the capsule then releases a stable, equal dose of the drug into the blood over a long period.
