半导体激光的新应用
The New Application of Laser Diode
摘要
半导体激光器(LD)在临床上有着广泛的用途。新型1 470 nm半导体激光与传统的1.06 μm YAG激光相比具有较强的组织吸收率, 与10.6 μm CO2激光相比则具有较高的切割效率, 适用肿瘤切除, 外科手术, 腹腔镜手术等微创手术。1 470 nm半导体激光的能量既能被血红蛋白吸收也能被细胞水吸收, 热量能集中在体积很小的组织内, 迅速汽化分解组织, 在治疗良性前列腺增生和妇科疾病上具有良好的应用前景。
Abstract
Lasers diode have a wide range in clinical use. Compared with the conventional 1.06 μm YAG laser, new 1 470 nm semiconductor laser has a strong tissue absorption rate .Compared with 10.6 μm CO2 laser, new 1 470 nm semiconductor laser has a high cutting efficiency. 1 470 nm semiconductor laser can be used for tumor resection, surgery, laparoscopic surgery and other minimally invasive surgery. 1 470 nm semiconductor laser energy can be absorbed by both hemoglobin and cell water, heat can be concentrated in a small volume of tissue, then tissue can be decomposed rapidly. 1 470 nm semiconductor laser also has a good prospect in the treatment of benign prostatic hyperplasia.
