ABSTRACT:
Disclosed herein is a laser scalpel which uses a krypton beam or a ray of light projected from a mercury lamp having a wave-length in the range of 3,950-4,200A as a guide light converging at the focal point or in the vicinity of the focal point of a laser beam for a surgical operation, for indicating focal point of said laser beam, which is equipped on its manipulator with a radiation detector or detectors enabling the detection of hematoporphyrin or isotopes built up in advance in the site of a tumor at said focus or in the vicinity thereof and to thus detect the tumor site at the time of irradiation of said laser beam for surgical operation and which makes it possible to simultaneously perform both diagnosis and treatment of the tumor.
