The ability of the combination of semiconductor laser and the laser probe with "fiber tip", which had a processed tip at the fiber, was demonstrated with animal experiment. The equipment constructed with this combination was evaluated clinically with the minor operations.
The laser unit used in this experiment was OSL-1000 (Osada electric industry co. ltd) which is composed with semiconductor laser with one watt continuous output. The fiber tip with needle shape was mainly used.
In animal experiment, skin and muscle of anesthetized rat was used. The skin could be cut with the carbonization at the surface and some coagulation under it. The muscle could be also cut with a little carbonization and some coagulation under it. The cut end of the vessels with less than almost 1mm diameter could be coagulated to make no bleeding.
In clinical, this equipment was applied in 14 cases of minor operations. It was used to stop minor bleeding or fine cutting of the tissue without any bleeding.
This equipment was found out to be useful for minor operation through these experiment.
