Fiber Laser For Myringotomy And Middle-Ear Surgery

描述（由申请人提供）：拟议计划的目标是 设计并制造了一个原型2710 nm（2.71 μ m）光纤激光器，用于 鼓膜切开术和中耳手术，并演示其操作。第2710章 nm波长对应于水的吸收光谱中的最大值， 从而降低激光功率要求。目前鼓膜切开术和 中耳手术通常涉及手术刀的使用。鼓膜切开术 中耳手术使用CO2激光器，但这些激光器很大， 并且在对于最大组织而言不是最佳的波长下操作 吸收该项目的主要目的是使 耳鼻喉科社区一种新型的光纤激光器，它体积小得多， 成本高、功率低、更灵活、比CO2激光器更可靠。的 光纤激光器系统将由791 nm二极管激光泵浦组成， 双包层掺铒和镨氟锆酸盐玻璃 (Er Pr：ZBLAN）光纤，其用作2710 nm光纤激光器。 将为该激光器选择市售组件。的 原型光纤激光器将由耳鼻喉科医生在不使用 人或动物受试者。激光器将进一步优化，小型化， 并在第二阶段的动物模型上得到证实。

DESCRIPTION (provided by applicant): The objective of the proposed program is to design and fabricate a prototype 2710 nm (2.71mum) fiber laser for use in myringotomy and middle-ear surgery, and to demonstrate its operation. The 2710 nm wavelength corresponds to a maximum in the absorption spectrum of water, thereby reducing the laser power requirement. Current myringotomy and middle-ear surgery generally involves the use of a scalpel. Some myringotomy and middle-ear procedures utilize CO2 lasers, but these lasers are large, expensive, and operate at a wavelength not optimized for maximum tissue absorption. The primary aim of this project is to make available to the otolaryngology community a new type of fiber laser which is much smaller, less costly, lower power, more flexible, and more reliable than the CO2 laser. The fiber laser system will consist of a 791 nm diode laser pump which is coupled into a double clad, erbium and praseodymium-doped fluorozirconate glass (Er,Pr:ZBLAN) fiber which acts as the 2710 nm fiber laser. Commercially-available components will be selected for this laser. The prototype fiber laser will be evaluated by an otolaryngologist without use of human or animal subjects. The laser will be further optimized, miniaturized, and demonstrated on animal models during Phase II.
