介绍了一种能够将多种激光耦合在手术显微镜上进行组织焊接和吻合,将普通激光刀变为显微激光刀的小型显微镜耦合器。详述了它的光学机械等系统的原理,并将3种国产激光器耦联于手术显微镜,进行了LAMA动物实验。 A small microscope coupler capable of coupling a variety of lasers on a surgical microscope for tissue welding and anastomosis and transforming an ordinary laser knife into a micro laser knife was introduced. The principle of its optical mechanical system was described in detail. Three kinds of domestic lasers were coupled to the surgical microscope and LAMA animal experiments were performed.
