Laser tissue welding is a novel technique where 20 % human albumin is put into a wound and 5 Watt Infrared laser of 850 nm is applied over it. At 60 degree centigrade temperature it leads to a formation of a watertight bond of proteins over the tissues by the photo polymerization effect of laser and gives about two weeks of healing in just two minutes. A costly 30 lac rupees machine is used for the purpose which is also not commercially available. I made a hand held laser gun (Photo1,2,3) of same specifications in just Rs 10,000 and successfully achieved the same result. Tissues such as spleen, liver, pancreas, brain and kidneys where sutures do not hold well are indications for this technique. The laser diode is fixed to a large aluminum heat sink for cooling. An on off switch is added for the control of laser. Laser diode is connected to a power supply of 2.3 volts and 5 amperes with an electrical wire.
