AI Technical Summary

Technical Problem

Traditional endoscopy can easily cause mucosal damage or perforation during the procedure, lacks real-time biomechanical feedback and intelligent early warning systems, and cannot quantify the operational risks.

Method used

The system employs a perception integration module to acquire multimodal data, performs spatiotemporal alignment and risk scoring through a data processing unit, and combines an active intervention module to adjust the mirror's stiffness or operational resistance. This includes a ring-shaped pressure sensor array, multispectral imaging and a 3D deformation tracking module, and is equipped with a collapsible snake-bone mechanism and an emergency braking latch.

Benefits of technology

It achieves multi-dimensional and accurate perception and real-time early warning of mechanical perforation risk, significantly improving the sensitivity and accuracy of early warning, and constructs a reliable physical-level safety fuse mechanism to effectively prevent mucosal damage and perforation.
