冠脉搭桥术用CO_2激光低能输出方法研究

An Approach for Getting Low CO_2 Laser Power in Laser-Assisted Microvascular Anastomosis

弱ＣＯ_２激光能量的输出及控制是ＣＯ_２激光冠脉搭桥术的核心技术之一。本文介绍了一种利用普通医用ＣＯ_２激光器获得弱激光能量输出的技术与方法。该方法具有激光输出功率稳定，并可调、输出光斑上能量密度均匀，光斑大小可控的特点，它很好地满足了搭桥仪对激光输出参数的要求；该方法还可应用于其它弱ＣＯ_２激光医疗仪器中。文中对设计原理进行了分析，并给出了设计实例。

Getting low CO2 Laser power is the key technology in laser-assisted microvascular anastomosis. The technology which is used to get low CO2 Laser power from the general CO2 Laser is presented in this paper, lts main advantages are that Laser power on Laser scalper is modifiable, spot size is controllable and energy density on the light spot is uniform. We give the design principle and an example for practical design in this paper.
