AI Technical Summary

Technical Problem

The existing cholangioscopes, because the thulium laser probe occupies the only instrument channel, cause conflicts between stone fragmentation and other surgical procedures, prolonging operation time, increasing surgical risks and reducing the convenience of operation.

Method used

Design a disposable cholangioscope with built-in thulium laser. The front end of the endoscope integrates a thulium laser module and an independent instrument channel. The thulium laser probe is retractable, and the camera module is independently arranged, enabling simultaneous operation of stone fragmentation, stone suction, and stone removal.

Benefits of technology

This reduces the number of procedure changes, shortens the operation time, lowers the risk of bile duct wall damage, and improves operational convenience and surgical efficiency.
