KTP/532激光(钾钛磷酸盐激光)是一种新型激光仪。特点为波长532nm固体型激光器产生可见光呈艳绿色,对组织的外侧热损害为0.3～2mm以上,光传送系统用带有接触和不接触的可曲性光导纤维引入鼻内窥镜,可通过内窥镜接近其它激光难到达的区域如鼻窦、鼻侧壁等。KTP/532激光描准光束和内窥镜光束同路,故去除病变准确率高。通常CO_2激光对水和组织吸收较高,组织能量扩散很小,临床主要用于切割和气化。Nd-YAG激光则组织吸收少而能量扩散大,主要用于凝固。KTP/532激光居中,它可通过改变功率、照射时间和光斑大小作切割、气化及凝固。
KTP / 532 laser (potassium titanium phosphate laser) is a new type of laser instrument. Features a wavelength of 532nm solid-state lasers to produce visible light was bright green on the outside of the tissue damage is 0.3 ~ 2mm above, the optical transmission system with contact with and without contact with the flexible optical fiber into the nasal endoscopy, Endoscopy close to other laser hard to reach areas such as sinus, nasal wall and so on. KTP / 532 laser beam and endoscopic beam of the same path, so remove the high accuracy of the lesion. Usually CO2 laser absorption of water and tissue is high, tissue energy diffusion is very small, the clinical mainly for cutting and gasification. Nd-YAG laser tissue absorption less energy diffusion, mainly for solidification. The KTP / 532 laser is centered and can be cut, vaporized and solidified by changing power, exposure time and spot size.
