Endoscope Insertion Tube Optical Code Detection

The patent replaces manual mechanical estimation with an automated optical detection system. Codes are printed on the insertion tube at known intervals, and an optical detector reads these codes to automatically calculate insertion depth, eliminating the need for manual measurement while improving precision.

The patent uses printed codes as visual copies of position information on the insertion tube. These codes serve as a simplified representation of depth data that can be read optically, replacing the need for complex mechanical measurement systems while maintaining high measurement precision.

The patent segments the insertion tube surface with printed codes at known intervals. This segmentation creates discrete, easily detectable position markers that simplify the detection process while enabling precise location measurement through automated optical reading of these segmented markers.

The patent introduces printed codes as an intermediary element between the insertion tube and the detection system. These codes act as a mediator that translates physical position into readable optical signals, enabling automatic detection without requiring complex direct measurement mechanisms.

The patent implements a feedback mechanism where the optical detector continuously monitors the position codes on the insertion tube during advancement. This real-time feedback information about insertion depth and orientation is fed back to the control system, enabling automatic tagging of images and ensuring complete body cavity scanning without requiring complex manual coordination.

The system performs self-service by automatically tracking its own position through the optical detection of codes on the insertion tube. The endoscopy system uses its own advancement motion to trigger automatic location determination and image tagging, eliminating the need for external complex positioning systems while improving scanning efficiency.
