Star Trek Now: Lasers Close Incisions

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.

Prof. Katzir set out to find the right temperature for optimal wound healing, and to perfect a device that could maintain this temperature. He is the first to apply the carbon dioxide laser, coupled to optical fibers, for wound closure under a tight temperature control.

“We think plastic surgeons will especially love this invention. Bonding tissues that heal well without scarring is a true art that few people possess,” says Prof. Katzir. This method, he says, will be much easier to master than suturing and will generate a watertight bond, preventing infections and accelerating healing. “It could also become a device for the battlefield, allowing soldiers to heal each other on contact with a laser wand,” says Prof. Katzir

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.)

Those of us who grew up watching the original Star Trek series are seeing Dr. McCoy's medical tools everywhere, from LifeBed Systems Like Star Trek's Sick Bay to Handheld Personal Biosensors.
