由光导纤维携载的单色和相干性激光照射,在医学上可用于血管瘤和其他皮肤病变的治疗、溃疡出血部位的止血及视网膜新形成血管的光凝固.最近激光照射试用于吻合动脉节段取得成功.在有肺动脉狭窄的狗中,激光可使肺动脉瓣叶形成孔眼,部分解除了狭窄.激光的一些特性提示它可用来使血管产生可控制的组织损伤.这些特性包括:对组织的光凝固作用,易被某些组织所吸收,能量的输出可控制,光线的方向能准确调节,可经
The monochromatic and coherent laser light carried by the optical fiber is medically useful in the treatment of hemangiomas and other skin lesions, hemostasis in the bleeding site of the ulcer, and photocoagulation of the newly formed blood vessels in the retina. The recent laser irradiation was used in the anastomotic artery section In dogs with pulmonary artery stenosis, the laser creates a perforation in the pulmonary valve leaflet that partially relieves stenosis, and some of the properties of the laser suggest that it can be used to produce controlled tissue damage to the blood vessels, including: Photocoagulation, easily absorbed by some tissues, the output of energy can be controlled, the direction of light can be accurately adjusted by
