NEEDED FIBER OPTICS FOR ENDOSCOPIC CO2 LASER SURGERY

CO2激光在内窥镜手术中的接受和广泛使用 等待安全、可靠、廉价的光纤系统允许 热固化能量的灵活传输与可视化 这件事。因为医学上需要这种设备，而且 因为它的制作和相关的研究开发是适合的 对于一家小型高科技公司来说，商业化是非常有希望的。 主动提出就此谈判第三阶段研究协议 话题已经由大型健康相关公司提出。 基于第一阶段的良好结果和可行性论证， 拟议的方法将研究用于外科纤维的卤化银。 更详细的光学制造。除了它的高度理论性之外 透过率，该材料无毒，不吸湿，灵活，和 可在中等温度下工作。一些新奇的制造 将采用改进措施，将光纤传输降低到1分贝/米以下 损失被证明主要是由于在 捏造。以前在提供必要的覆层和端部时遇到的困难 将创新地解决Windows问题，使其有效、可扩展 用于外科团队评估的原型纤维。

Acceptance and widespread use of the CO2 laser in endoscopic surgery still awaits a safe, reliable and inexpensive fiber optic system to permit flexible delivery of thermalizing energy collinear with visualization of the event. Because of the need for this device in medicine and also because its fabrication and related research and development are suitable for a small high technology firm, commercialization is very promising. Unsolicited offers to negotiate a Phase III research agreement on this topic have been made by large health related companies. Based on favorable results and a demonstration of feasibility in Phase I, the proposed approach will investigate silver halide for surgical fiber optic fabrication in more detail. In addition to its high theoretical transmissivity, the material is non-toxic, non-hygroscopic, flexible, and workable at moderate temperatures. A number of novel fabrication refinements will be employed to reduce, below 1 dB/M, fiber transmission losses shown to be due primarily to scattering centers incurred in fabrication. Prior difficulties in providing necessary cladding and end windows will be innovatively addressed to make effective, expendible prototype fibers for evaluation by surgical teams.
