Steerable Endoscope Tube Structure for Low-Discomfort Navigation

The endoscope shaft is divided into multiple rigid segments that can be independently positioned. Each segment can be rotated or angled relative to adjacent segments, enabling steering capability through a series of discrete, simple mechanical joints rather than a continuous flexible structure.

The endoscope incorporates dynamically adjustable rigid segments that can change their relative angles during insertion and positioning. This allows the device to adapt its shape dynamically to navigate anatomical passages while maintaining the structural integrity of individual rigid components.

By segmenting the shaft into discrete rigid sections with simple interconnections, each component can be manufactured using standard rigid fabrication processes rather than requiring complex flexible tube formation and assembly, significantly reducing manufacturing cost.

The rigid segmented structure with simple mechanical joints can be manufactured more economically than flexible structures, making the overall device more cost-effective while maintaining essential steering functionality.

Each rigid segment maintains full structural strength of solid material, and the segmentation itself creates discrete load-bearing units. The simple mechanical joints between segments preserve strength by minimizing stress concentration points compared to continuous flexible structures.

The dynamic adjustment of rigid segments allows strength to be concentrated where needed in each segment while enabling steering through controlled, localized movements rather than requiring the entire structure to be flexible and weaker.
