Researchers from Tel Aviv University have developed a new device to heat body tissue in a controlled manner by using carbon dioxide lasers. This technique, called ‘laser welding’, can be used by surgeons to seal wounds inside as well as outside the body. The research team was headed by Prof. Abraham Katzir from the university’s Applied Physics Group.

Highlights of the new technique
a. In this technique, carbon dioxide laser is used along with optical fibers to close wounds under tight temperature control.
b. Unique optical fibers, made from silver halide and developed at Tel Aviv University, are used here.
c. The laser’s energy is delivered via the fibers to heat the bonded cut and control the temperature.
d. These fibers also make it possible to bond tissues inside the body.
e. Results from clinical trials on people undergoing gall bladder removal surgery were positive.
f. Trials also showed that this technique can be applied to bond cuts on the cornea, bladder, intestines, blood vessels or trachea, tissues inside the body on organs such as the kidney and even in brain surgery.
g. It is ideal for healing soft tissues.
