Not much has changed in the last 2,000 years when it comes to suturing together cuts and wounds. Even with microsurgery techniques, infection and permanent scarring remain major concerns.
To minimize these dangers, doctors tried using a carbon dioxide laser to seal wounds, but without the ability to control the heat of the laser, the technique created even greater risks. Until now.
Using carbon dioxide lasers to seal wounds inside the body and out with a technique known as “laser welding,” a team of Tel Aviv University researchers have perfected a new device to heat body tissue in a precisely controlled manner. The work of the research team, headed by Prof. Abraham Katzir from TAU’s Applied Physics Group, could change the way surgeons bond cuts on the surface of our skin and inside our bodies during surgery.
