LASER THERAPY METHOD, HIGHLY LASER BEAM-ABSORBING MEDIA TO BE USED IN THE THERAPY AND LASER THERAPY APPARATUS WITH THE USE OF THE SAME

摘要

The present invention relates to a laser treatment method and a laser treatment apparatus which can cause thermal damage such as evaporation or necrosis due to coagulation to the tissue which is to be subjected to thermal damage in a sure manner regardless of absorption percentage of laser beam due to the color tone or composition of the organic tissue, thereby enabling diffusion of cancer cells due to abnormal high pressure from evaporation of the diseased tissue or the like to be prevented, and the laser treatment method and the laser treatment apparatus have a configuration wherein a laser beam absorption medium is injected between the diseased tissue which is to be the object of laser irradiation and the laser beam output end, and a laser beam is cast onto the aforementioned laser beam absorption medium so as to cause thermal damage such as evaporation or coagulation to the aforementioned diseased tissue which is the object of laser irradiation, and furthermore, in the event of abnormal pressure occurring due to evaporation of the diseased tissue, the aforementioned pressure is vented externally.
