ABSTRACT:
A focal point direct observation type laser scalpel device has a construction wherein laser beams generated by an infrared laser generator and transmitted through an optical fiber adapted for infrared laser beams and visible rays issued from a visible ray source and transmitted through optical fibers adapted for visible rays are passed through one common converging lens system so that recognition of the focal point of the laser beams is accomplished by visual observation of the focal point of the visible rays.
