- Surgical Instrumentation
Background:
- Flexible endoscopy is crucial for gastrointestinal (GI) diagnostics and therapeutics.
- Current tools limit advanced endoscopic surgical interventions.
- Improved instrumentation is needed for complex procedures.
Purpose of the Study:
- To introduce a novel master-slave robotic system for flexible endoscopy.
- To enhance manipulation capabilities during endoscopic procedures.
Main Methods:
