Optical fibre devices for sideways delivery of laser light during keyhole surgery

多模光纤通常用于传输高功率激光，该激光从光纤末端发射，在手术期间照射组织。对于静脉输送激光治疗心脏颤动（心脏扑动），我们需要一个侧面定向的照明光束。然而，目前还没有可靠的方法在侧面定向光束中传输高功率激光。利用麦考瑞大学已经开发的紫外线激光光纤加工专业知识，我们建议开发和表征新的基于光纤的设备，这种设备将允许光的可控横向传输。

Mulitmode optical fibres are typically used to deliver high power laser light which is emitted from the end of the fibre to irradiate tissue during surgery. For intravenous delivery of laser light in the treatment of cardiac fibrillation (heart flutter) we require a sideways-directed illuminating beam. However reliable methods of delivering high power laser light in a sideways-directed beam are not currently available. Using the ultraviolet laser fibre processing expertise already developed at Macquarie University, we propose to develop and characterise novel fibre-based devices which would allow controllable delivery of light sideways.
