ABSTRACT:
A laser knife includes a tubular member adapted to be inserted into the coeloma by being inserted into the forceps channel of an endoscope, a pair of oppositely located laser radiation emitter and acceptor members on the distal end of the tubular member, a laser radiation receiving element disposed on the acceptor for accepting laser radiation which is used for purpose of cautery subsequent to the completion thereof and performing a photoelectric conversion of such radiation, a laser radiation transmission member for transmitting laser radiation to the emitter, and a laser radiation isolator interposed between the transmission member and a laser oscillator and responsive to a laser radiation accept signal from the element for interrupting the supply of laser radiation into the transmission member. In this manner, unwanted irradiation of normal tissues with the laser radiation is automatically terminated after a desired affected part has been cauterized.
