ABSTRACT:
A laser knife comprises a tubular member adapted to be passed through a forceps channel of an endoscope for insertion into a coeloma, holders disposed at the distal end of the tubular member for holding an affected part within the coeloma which is to be cauterized, a laser radiation transmission member for irradiating the affected part held by the holders with radiation from a laser, and a pad on the holders for accepting the laser radiation subsequent to the completion of the cautery, thus preventing the irradiation of normal tissues with the laser radiation.
