阅读说明：本技术 柔性内窥镜以及制造其的方法 (Flexible endoscope and method of manufacturing the same ) 是由 尼古拉斯·马修·格尔博 乔治·加里·文特雷拉 于 2016-02-26 设计创作，主要内容包括：内窥镜包括手柄,手柄连接到柔性的、可转向的抗扭结的插入管。内窥镜插入管可以包括轴、邻近轴的远端的较低硬度的部分和定位在较低硬度的部分和中间硬度的部分之间的较高硬度的部分。内窥镜插入管还可以包括第四热塑性塑料层压件部分,其邻近轴的近端并具有较高的硬度。制造内窥镜插入管的方法可以包括：将具有一个、两个或更多个侧部狭槽的心轴和衬里插入轴中,其中衬里定位在心轴和轴之间；使衬里的结合部分结合到轴的内表面；使衬里的其它部分与轴隔开；以及将第一偏转丝插入在轴和衬里的未结合部分之间的间隙中。(The endoscope includes a handle connected to a flexible, steerable, kink-resistant insertion tube. The endoscope insertion tube may include a shaft, a lower durometer section adjacent a distal end of the shaft, and a higher durometer section positioned between the lower durometer section and the intermediate durometer section. The endoscope insertion tube may further include a fourth thermoplastic laminate section adjacent the proximal end of the shaft and having a higher durometer. The method of manufacturing an endoscope insertion tube may include: inserting a mandrel having one, two, or more side slots and a liner into the shaft, wherein the liner is positioned between the mandrel and the shaft; bonding the bonding portion of the liner to the inner surface of the shaft; spacing the other portion of the liner from the shaft; and inserting a first deflection wire in a gap between the shaft and the unbonded portion of the liner.)
