Endoscopes TRIZ Cases

A subject observation system emits blue region light at 400 to 440 nm combined with wavelength converted yellow fluorescence.

Stereoscopic imaging resolves absolute location precision limits by superimposing graphical indicators on visual data for accurate volumetric assessment.

Segmented positive lenses with controlled curvature radii disperse light rays to reduce heat generation in endoscope illumination systems.

Sliding stopper member locks shaft rotation within connection sleeve to correct bending direction misalignment during surgical procedures.

Merging separate optical channels into one light guide reduces the insertion portion diameter while maintaining dual functionality for stone shattering.

An endoscopic hood integrates a resection wire to enable single-step tissue cutting during mucosal resection procedures.

Segmented bipolar electrode design with coaxial active and neutral electrodes ensures reliable plasma ignition at the distal end.

External receivers analyze phase and time differences of capsule signals to locate the device, resolving ambiguity in physiological data interpretation.

Merging separation functions into the outer casing reduces part count and weight while maintaining board stability.

Flexible polymeric elevator reduces wire guide damage while maintaining structural integrity and fluid flow.

Integrated elongated channel enables simultaneous visualization and stapling, eliminating the need for additional patient incisions.
