Bending tube for endoscope

摘要

A bending tube extends between the flexible tube and the distal end portion of an endoscope, and is subject to a bending control from the control unit of the endoscope for swinging the distal end portion in a desired direction. The bending tube comprises a braided structure and an outer framework. The resulting construction permits the bending tube to bend freely in all directions and prevents the outer shell from being damaged by the framework and also increases the interior space of the bending tube.
