AI Technical Summary
The existing inflatable structure of the curved fixation device for gastrointestinal endoscopes is easily damaged and is inconvenient to replace, install, and adjust the bending angle.
The endoscope employs two sets of moving circular blocks and one set of fixed circular blocks, combined with an electromagnet design, to achieve angle adjustment and bending length adjustment of the endoscope tip.
It solves the problems of inflation damage and inconvenient installation, and enables flexible angle adjustment and bending length control of the endoscope tip.
