中国专利有许多是垃圾，这是路人皆知有口皆碑的事情了。
美国专利会不会好一点？搜索内窥镜（endoscope），一堆一堆的专利，看得人头大。有谁能告诉我哪些专利是有点儿意思的值得浪费一点时间看一遍的？
以下是1992年的一个专利中的若干Description
In recent years, thin, flexible optical fibers have allowed for the remote viewing, photography, biopsy and surgery of organs and tissues. Such thin, flexible optical fibers, also known as fiber optics, are incorporated in endoscopes to enable the transmission of light to illuminate the internal space being viewed and/or enabling the object so illuminated to be viewed. Generally, the viewing capability is accomplished by aligning multiple fibers so that the relative position of each fiber is the same at each end of the bundle. The methods and apparatus transmitting images thereon is well known.
别人已经well know的东西，我就是百思不得其解。
Typical endoscopes presently include a bundle of fiber optics, each having a light transmitting core and an outer cladding. The light enters the end of the core and through internal reflections passes down the core to the other end. A multiplicity of such fiber optics may be gathered together in a bundle along which light passes to illuminate the object at the distal end of the endoscope. A second bundle, arranged in a coherent manner, may also be incorporated to provide a means of viewing the illuminated area at the distal end of the endoscope. Various other channels, as described above, may be provided for the transmission of fluids, the control of miniature tools or surgical instruments or any other desired function. The illuminating bundle, the visualizing bundle and the auxiliary channels are gathered together in a multi-lumen or hollow cylindrical sheath.
看来这个小不点的东西是相当地复杂，结构丰富、五脏俱全。
我感兴趣的，依然，仅仅是里面的光纤是怎么做的。
