Finally, Lasers That Heal Wounds Rather Than Creating Them

Generally , when you mean of a hot laser being pointed at your trunk , you ’d anticipate it to create a hole rather than seal off one up . And most of the time , you ’d be correct . But Abraham Katzir , a physicist at Tel Aviv University , has just begun human visitation of healing lasers that promise less scarring , quicker healing and less endangerment of contagion when compare to traditional stiches .

As you could see from the photos to the left field , the laser - cure cut on the bottom heal much better than the suture - sew cut on top . So how do they keep the laser safe and preclude it from doing more legal injury than good ?

To overcome this trouble , Katzir and his colleague develop a laser - base scheme with a feedback grommet that prevents overheating . First , they had to settle the optimal temperature at which build thaw but can still cure ( about 65 degrees Celsius ) . Then the chemical group created a pen - sized tool that incorporates optical fibers : one that transport a carbon dioxide - powered infrared laser to the wounding with pinpoint precision , and another that lead from the penitentiary to an infrared detector , which evaluate the temperature and ensures that the heating system remains within the idealistic range , between 60 and 70 degrees . All a surgeon has to do is move the pen ’s bakshis along the cut , strengthening and seal the dyer’s rocket with a solder of water - soluble protein .
