Embodiment Construction

[0018] All terms below are just for the convenience of description, and should not be construed as limiting the invention. Unless otherwise stated, the term "a" or "a" shall be understood to include one or more of the referenced item. The term "arrangement" includes any type of arrangement, such as two-dimensional fiber optic arrangements for deformable image bundles.

[0019] Such as Figure 6 As shown, the present invention relates to a method of producing a leachable fiber bundle 10 suitable for use as an image conductor, a guide for an endoscope, or a guide for transmitting optical signals. The leach fiber bundle 10 includes a large number of optical fibers 12, which may be as small as 10 microns or even smaller. Such as Figure 7 As shown, the leach fiber bundle 10 may be enclosed in a protective covering material 14, preferably a flexible polymeric material. Of course, the covering 14 is not necessary.

[0020] To produce the leached fiber bundle 10, a quantity of o...

Abstract

A mesh (36) is placed around a bundle (32) of fused glass fibers. The bundle is then immersed in a leaching bath (44). The ends of the bundle are protected from the bath fluid by ferrules (34). Some of the glass of the bundle is leached out, so as to provide a flexible fiber bundle.

Description

technical background [0001] The present invention relates to a leachable fiber bundle for optical signal communication commonly used in endoscopes, and more particularly to an improved method of producing such a leachable fiber bundle of high quality and reliability. [0002] It is known to produce image guides, guides for endoscopes, guides for transmitting light signals in the form of leachable fiber bundles. The aforementioned leaching fiber bundle includes a large number of optical fibers, which can be arranged in a regular and orderly manner, and the diameter of each optical fiber is very small, such as 10-100 microns. The leached fiber bundle can be formed by drawing fiber bundle blanks in the form of glass rods and / or tubes with a certain amount of fiber blanks pre-positioned between or on each fiber blank Encapsulated with at least some leachable glass spacers. The optical fibers in the fiber bundle semi-finished product are drawn to the desired size and after the fi...
