We proposed a concept of a handy-type laser surgical unit for use in outpatient, in ward and in open-air field. To investigate the possibility of the concept, a handy-type semiconductor laser surgical unit was developed experimentally using 2-watts power laser diode with no built-in electrical cooling unit (Peltier chip) and a small rechargeable battery. The drive circuit was constructed with only current limit and ACC circuits. The laser diode was cooled with heat sink and simple fan. Laser irradiation was set to stop at 30 degree Celsius by monitoring the temperature of laser diode with thermistor temperature sensor. With this system, 1.18 watts of laser power at the end of optical fiber with both 600 and 900μm core diameter, and about 30 minutes of continuous irradiating time with Ni-Cd battery (4.8V 1,500mA/h) could be obtained with no over heating in laser diode. The result showed that the high power semiconductor laser could be driven with small battery when specially designed. In an animal experiment, small bleeding could be managed with contact irradiation method. This kind of simple laser surgical unit is considered to be useful for the management of small bleedings in clinical.
