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 等待一个安全、可靠和廉价的光纤系统， 与可视化共线的热化能量的灵活输送， 该活动内情的 因为医学上需要这种设备， 因为它的制造和相关的研究和开发是合适的， 对一个小型的高科技公司来说，商业化是很有希望的。 主动提出就第三阶段研究协议进行谈判， 一些大型的健康相关公司已经提出了这一主题。 根据第一阶段的有利结果和可行性证明， 所提出的方法将研究用于外科光纤的银 更详细的光学制造。 除了理论上的高 transmitting，该材料是无毒的，不吸湿的，柔性的，和 可在中等温度下使用。 一些新的制造 将采用改进措施，使光纤传输降低到1 dB/M以下 损失显示主要是由于分散的中心， 捏造 在提供必要的覆层和端部 窗口将创新地解决，使有效， 原型纤维供外科团队评估。

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.
