The laser in surgery.
Current developments in treatments for diseases of the spine and whole body in general is moving towards developing less invasive surgical techniques, called on the international medical language "minimally invasive surgery" which allows to decrease aggression human body, a decrease also of periods of hospitalization, absenteeism and the cost of treatments in general.
One example known for years for the general population would be the development of laparoscopy practiced by almost all the general surgeons, this technique that may resolve abdominal diseases "without opening the abdomen," as was done classically through small holes made in the skin of the abdomen to the introduction of instruments and appliances that let you watch a television camera particularly suited for these operations.
With the development and refinement of laser surgery, the Americans introduced the application of this to treat multiple conditions in the human body, this technology does not fail to astonish scientists and doctors each day to observe the results of operations where is used, and minimal complications observed.
Laser means in English: "light amplification by stimulated emission of radiation" and the start of development was in the decade of the 60s, by Maiman, based on the theories of the atom to develop Einstein in 1917.
In practice, the laser is a concentrated beam of light, which when run on a part of human body tissue has the characteristic of being absorbed by the tissue, resulting in the evaporation or disappearance of the area, this translates that a surgeon can, for example, remove a tumor without touching it with one directing a laser light beam toward the tumor tissue. All this makes traditional metal instruments (forceps, etc..) Much thicker and thicker than a fiber laser are not necessary, being much less traumatic surgery and get a better result.
