Laser welding of body tissues may provide a means of closing surgical incisions that is better than traditional methods. The technique, pioneered by Professor Abrahim Katzir of Tel Aviv University, can also be used with great efficacy on cuts made inside our bodies during surgery.
Successful clinical trials have already been made on people undergoing gall bladder removal surgery. Following surgery, four cuts were left on the skin of the abdomen, two of which were sutured and two laser-bonded. The results of the trials suggest that the laser-bonded tissues heal faster, with less scarring.
If this sounds like space age medicine, you're right. Fans of Star Trek: The Next Generation will no doubt find this idea familiar. Starting in the 2250's, the laser scalpel was the surgical instrument of choice and was available in different wavelengths for varied cutting strength and depth of cut.
However, as far as Dr. Katzir's work on closing surgical incisions is concerned, I'm more interested in the dermal regenerator.The dermal regenerator was used on a number of occasions in the television show to heal cuts and burns. (Tip to Dr. Katzir - it is also useful in removing scars.)
